What is the area of this figure? 5 in 6 in 15 in 16 in 10 in 20 in
Answer:
230 in.²
Step-by-step explanation:
20 · 10 = 200 in.²
5 · 6 = 30 in.²
200 in.² + 30 in.²
Answer:
230 sq in
Step-by-step explanation:
You can find entire area (20 x 16) and subtract out the area of the missing piece (15 x 6)
20 x 16 = 320
15 x 6 = 90
320 - 90 = 230
Huey can wash 6 cars or mow 3 lawns in one hour. Dewey can wash 3 cars or mow 3 lawns in one hour. Louie can wash 3 cars or mow 6 lawns in one hour. They each work 8 hours per day. If two of them wash cars and one mows lawns then at most they can wash cars and mow lawns. Enter whole numbers.
At most, they can wash 96 cars and mow 96 lawns.
To determine the maximum number of cars they can wash and lawns they can mow, we need to consider the work rates of each person and the total number of hours they work.
Huey can wash 6 cars or mow 3 lawns in one hour, so in 8 hours, he can wash 6 \(\times\) 8 = 48 cars or mow 3 \(\times\) 8 = 24 lawns.
Dewey can wash 3 cars or mow 3 lawns in one hour, so in 8 hours, he can wash 3 \(\times\) 8 = 24 cars or mow 3 \(\times\) 8 = 24 lawns.
Louie can wash 3 cars or mow 6 lawns in one hour, so in 8 hours, he can wash 3 \(\times\) 8 = 24 cars or mow 6 \(\times\) 8 = 48 lawns.
Since two of them wash cars and one mows lawns, the maximum number of cars they can wash is the sum of the maximum cars each person can wash, which is 48 + 24 + 24 = 96 cars.
The maximum number of lawns they can mow is the sum of the maximum lawns each person can mow, which is 24 + 24 + 48 = 96 lawns.

calculate the size of angle AEF
Answer:
Accuate Angel 230 digre
Answer:
90 degrees
Step-by-step explanation:
The sum of the measures of interior angles in a quadrilateral is 360 degrees. A quadrilateral is any shape that has 4 sides. ABCD is a square, and squares have 4 sides, so the sum of the angles inside of the square will be equal to 360. A square has 4 angles, each with equal measure, so to find the measure of one angle, divide 360 by 4: 360/4=90. Each angle in a square measures 90 degrees.Triangle DEF is an equilateral. This means that each side is equal, but it also means that each angle will be equal too. The sum of the measure of interior angles in a triangle is 180 degrees, and a triangle has 3 angles, therefore you can find the measure of each angle in an equilateral by dividing 180 by 3: 180/3=60. Each angle in an equilateral triangle measures 60 degrees.The measure of a straight line is always 180 degrees. CDF is a straight line, and it is made up of 3 angles:-Angle CDA
-Angle ADE
-Angle EDF
Since the measure of CDF has to be 180 degrees, the measures of angles CDA, ADE, and EDF must add up to 180.Angle CDA is an angle of a square, so it is equal to 90 degreesAngle EDF is an angle of an equilateral triangle, so it is equal to 60 degrees.The angles must add up to 180, so 90+60+ADE=180You can subtract 90 and 60 from 180 to find the measure of ADE: 180-90-60=30The question tells us that triangle ADE is isosceles. There is a theorem called base angles theorem, and it states that if two sides of a triangle are equal in length, then the two angles opposite from them will be equal in measure. Using this theorem, we can find that the measure of angle ADE is equal to the measure of AED. We already found out that ADE is 30 degrees, so AED is also 30 degrees. But the angle we are looking for is AEF:AEF is made up of angles AED and DEF, so the measures of angles AED+DEF=AEF. DEF is part of the equilateral triangle, so we know it is 60 degrees. We already found that AED is 30 degrees, so add 30 and 60 degrees: 30+60=90. AEF is 90 degrees.Viola makes gift baskets for Mother’s Day.

A bank offers two credit cards. card a gives 1.5% cash back on every purchase. card b gives 2% cash back on every purchase but has a $95 annual fee. when is card b a better deal than card a? (assume no interest is paid on purchases.)
Card B is a better deal than Card A when the total annual purchases exceed $4,750. This is because the additional 0.5% cash back on Card B compensates for the $95 annual fee.
To determine when Card B becomes a better deal than Card A, we need to compare the cashback earnings of both cards and take into account the annual fee of Card B.Card A offers a flat 1.5% cash back on every purchase, while Card B offers a higher 2% cash back but also has a $95 annual fee.
To find the break-even point, we need to calculate the difference in cash-back earnings between the two cards and equate it to the annual fee:
2% - 1.5% = 0.5% cash back difference
To cover the $95 annual fee, the total annual purchases must generate an additional 0.5% cash back compared to Card A:
0.5% of x = $95
Solving for x, we find that the total annual purchases must exceed $4,750 for Card B to be a better deal than Card A. At this threshold, the additional 0.5% cash back on Card B compensates for the annual fee, making it a more advantageous option for the cardholder.

What is a Two Way Table?A two-way table displays the frequencies or relative frequencies of two categorical variables. One category is represented by rows, while the other is represented by columns.
How to solve the question?In the question, we are asked to complete the two-way table as per the given information.
In the first row, second column:
The box needs the data for the number of spenders who want to become savers.
In the provided information, we have been told that of the 140 people who identified themselves as spenders, 78 said they would continue being spenders, while the rest said they would like to be savers.
Thus, the number of spenders who want to be savers = 140 - 78 = 62.
Hence, entry is 62.
In the first row, third column:
The box needs the data for the number of people who now want to continue as savers, or become one.
This can be shown as the sum of the first two readings of the row.
Thus, the total number of people who now want to continue as savers, or become one = 112 + 62 = 174.
Hence, entry is 174.
In the second row, first column:
The box needs the data for the number of savers who want to become spenders.
In the provided information, we have been told that of the 120 people who identified themselves as savers, 112 said they would continue being savers, while the rest said they would like to be spenders..

Find the equation of the line that
is parallel to y = 4x + 1 and
contains the point (1, 1).
y = [? ]X + [ ]
The equation of a line is:
\( \displaystyle \large{y - y_1 = m(x - x_1)}\)
Since the line has to be parallel to line y = 4x+1. Hence, m = 4.
\( \displaystyle \large{y - y_1 = 4(x - x_1)}\)
Given point is (1,1). Let this be the following:
\( \displaystyle \large{(x_1,y_1) = (1,1)}\)
Substitute the point in.
\( \displaystyle \large{y - 1 = 4(x - 1)}\)
Convert the equation in a slope-intercept form or function form.
First, distribute 4 in the expression.
\( \displaystyle \large{y - 1 = 4x - 4}\)
Add 1 on both sides.
\( \displaystyle \large{y - 1 + 1 = 4x - 4 + 1} \\ \displaystyle \large{y = 4x - 3}\)
Hence, the line that is parallel to y = 4x+1 and passes through (1,1) is y = 4x-3
the average rain fall in cuba in the summer is 5.3 inches per month. if cuba gets 6.3 inches in june and 7.1 in july how much rain do they need in august to exceed their average
Answer:
They need more than 2.5 inches.
Step-by-step explanation:
average = 5.3
June: 6.3
July: 7.1
August: x
The average of the amounts for June, July, and August is
(6.3 + 7.1 + x)/3
To exceed the average, the average must be greater than 5.3.
(6.3 + 7.1 + x)/3 > 5.3
Multiply both sides by 3.
6.3 + 7.1 + x > 15.9
x + 13.4 > 15.9
Subtract 13.4 from both sides.
x > 2.5
Answer: They need more than 2.5 inches.

Hannah's debt-to-equity ratio when her liabilities was $30,000 (excluding her mortgage of $100,000 ) and her net worth is $45,000 is 0.75.
Debt-to-equity ratio is a financial ratio that measures the proportion of total liabilities to shareholders' equity. To calculate the debt-to-equity ratio for Hannah, we need to first calculate her total liabilities and shareholders' equity.
We are given that Hannah has liabilities of $30,000 excluding her mortgage of $100,000. Therefore, her total liabilities are $30,000 + $100,000 = $130,000.
We are also given that her net worth is $45,000. The net worth is calculated by subtracting the total liabilities from the total assets. Therefore, the shareholders' equity is $45,000 + $130,000 = $175,000.
Now we can calculate the debt-to-equity ratio by dividing the total liabilities by the shareholders' equity.
Debt-to-equity ratio = Total liabilities / Shareholders' equity = $130,000 / $175,000 = 0.74 (rounded to two decimal places)
Therefore, Hannah's debt-to-equity ratio is 0.74, which is closest to option 0.75.

a) The complete beta (ß) decay reaction for 60Co is 60 (superscript) 27 (subscript) Co → 60 (superscript) 28 (subscript) Ni + -1 (superscript) 0 (subscript) e.
b) The complete beta (ß) decay reaction for 18F is 18 (superscript) 9 (subscript) F → 18 (superscript) 10 (subscript) Ne + -1 (superscript) 0 (subscript) e.
Beta (ß) decay is a type of radioactive decay in which a beta particle, which can be either an electron or a positron, is emitted from the nucleus of an atom. It occurs when a neutron is converted into a proton or vice versa, along with the emission of a beta particle.
In the first given example, the beta (ß) decay of 60Co is represented as 60 (superscript) 27 (subscript) Co → 60 (superscript) 28 (subscript) Ni + -1 (superscript) 0 (subscript) e. This means that a cobalt-60 nucleus (with 27 protons and 33 neutrons) decays into a nickel-60 nucleus (with 28 protons and 32 neutrons) by emitting a beta particle, which is represented by -1 (superscript) 0 (subscript) e.
Similarly, in the second given example, the beta (ß) decay of 18F is represented as 18 (superscript) 9 (subscript) F → 18 (superscript) 10 (subscript) Ne + -1 (superscript) 0 (subscript) e. This indicates that a fluorine-18 nucleus (with 9 protons and 9 neutrons) decays into a neon-18 nucleus (with 10 protons and 8 neutrons) by emitting a beta particle.

What is the domain? I need help on this problem
The domain of the function \(f(x) = \sqrt{\frac{1}{3}x + 2\) is (d) x ≥ -6
How to determine the domain of the functionFrom the question, we have the following parameters that can be used in our computation:
\(f(x) = \sqrt{\frac{1}{3}x + 2\)
Set the radicand greater than or equal to 0
So, we have
1/3x + 2 ≥ 0
Next, we have
1/3x ≥ -2
So, we have
x ≥ -6
Hence, the domain of the function is (d) x ≥ -6
