find the measure of angle theta. Round to 3 significant digits.
Answer: θ = 48.2°
Step-by-step explanation:
The left side of the given triangle is a right triangle with base (adjacent to θ) = 2 and hypotenuse = 3
\(\cos \theta = \dfrac{adjacent}{hypotenuse}\\\\\\\cos \theta=\dfrac{2}{3}\\\\\\\theta =\cos^{-1}\bigg(\dfrac{2}{3}\bigg)\\\\\\\theta = 48.1896\)
rounded to three significant digits = 48.2°
The measure of angle theta is 48.2 degrees.
What is cosine of an angle?In a right angled triangle, the cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.
According to the given question
We have a right triangle
Let the be ABC in which ∠ACE = θ
And, AE is a perpendicular bisector so CE = 4/2
Now in right angled triangle ACE, the cosine of θ is given by
cosθ = length of the adjacent side/ hypotenuse
⇒ cosθ = \(\frac{CE}{AC}\)
⇒cosθ = \(\frac{2}{3}\)
⇒ θ = \(cos^{-1}( \frac{2}{3} )\)
⇒ θ = 48.2 degrees
Hence, the measure of angle theta is 48.2 degrees.

Step-by-step explanation:
hello can someone help! i will make them brainliest!
Answer:
B ( 92 degrees)
Step-by-step explanation:
1. Find y
In order to find z, we need to find y.
All triangles add up to 180 degrees, so y would be
180 - (48 + 44) = 88
y is 88 degrees
2. Find z
So now we know y is 88, we can find z
The circle of all angles of y and z = 360 ( because full angle)
so our equation is:
(88 + z)2 = 360
Divide by 2
88 + z = 180
z = 92

if i have to do 60 hours in 5 weeks how many mintues do i do a day
Answer:
102 minutes
Step-by-step explanation:
If you have to work 60 hours in five weeks, there are seven days in a week so I multiply 7 by 5 (5 being the number of weeks) and I divide that by 60, getting 1.7 hours a day, which is 102 minutes. Hope this helped!
Answer:
Hey there!
60 hrs in 5 weeks is equal to 3600 minutes in 35 days.
So, each day you would have to do 102.86 minutes.

A cylindrical cake is made in a pan that has a diameter of 10
inches and a height of 2 inches. What is the total surface
area of the icing on the cake?
141.37 square inches
Answer:
about 141.4 square inches
Step-by-step explanation:
You want the area of icing on a cake that is 10 inches in diameter and 2 inches high.
IcingThe icing on a cake covers the lateral surface area and the area of the circular top. In terms of diameter, the sum of those areas is ...
icing area = πdh +(π/4)d² = πd(h +d/4)
icing area = π(10 in)(2 in + (10 in)/4) = π(10 in)(4.5 in)
icing area = 45π in² ≈ 141.4 in²
The area of icing on the cake is about 141.4 square inches.

Find the best measure of variability for the data and determine which player was more consistent.
Player B is the most consistent, with an IQR of 3.5.
Player B is the most consistent, with a range of 10.
Player A is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 5.
Answer: Player B is the most consistent, with an IQR of 3.5.
Step-by-step explanation:
For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).
For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).
Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

Is 4/5 divided by 1/3 greater than 1
Answer:
Yes
Step-by-step explanation:
It's 12/5 or also 2.4
Answer:
yes
Step-by-step explanation:
remember how to do fraction operations :
a/b / c/d = a×d / b×c
that is why you can also say it is the same as the multiplication with the upside-down fraction
a/b / c/d = a/b × d/c = a×d / b×c
in your case here
4/5 / 1/3 = 4/5 × 3/1 = 12/5
and that is definitely greater than 1.
21 is less than w+6 solve the inequality for w
Step-by-step explanation:
21<w+6
honestly I think im wrong because I didn't really get the question, sorry
Answer:
15 < w
Step-by-step explanation:
We are given the expression "21 is less than w + 6" and are asked to solve this inequality for "w".
To do so, we first need to create the actual inequality, if 21 is less than w + 6, then the sign we should use is the less than sign (<).
21 < w + 6
Now we solve for w, which is by isolating w :
21 < w + 6
Subtract 6 from both sides :
15 < w

A vine grows 7.5 feet every 5 days. Is the length of the vine on the last day proportional to the number of days of growth? Explain.
Answer:
yes since it grows at a constant rate at 7.5 feet/5 days so it should be proportional if you treat it as an algebraic equation and solve for the rate of 1 day's growth but that gives an assumption that no factors would affect the growth and it'll always grow at that exact rate

A gardener uses a total of gallons of gasoline in one month. Of the total amount
of gasoline, was used in his lawn mowers. How many gallons of gasoline did the
gardener use his lawn mowers in one month?
Answer:
D. 36.9
Explanation:
three-fifths of 61.5 is 36.9!
Answer:
D. 36.9
Step-by-step explanation:
The total amount of gallons the gardener typically uses in a month is 61.5 gallons. Since the gardener used 3/5 gallons, we know that 5/5 is 61.5 gallons. So you would have to divide 61.5 by 5 in order to get 1/5 of the gallons which would be 12.3. Then you have to multiply the 12.3 by 3 in order to get 3/5 of how much the gardener used which is 39.9 gallons. I hope this helped!

Step-by-step explanation:
Look at the image below.what is the area of the parallelogram
The area of the parallelogram given in the image is 72 square units.
The area of a parallelogram is taken as base × height because it can be divided into two different parts and then reshuffled to make a rectangle, whose area is also base × height.
We know that the area of a parallelogram = base × height ......(i)
Also, we are given quantities for base = 6 units
and height = 12 units
So, putting the values in equation (i), we get
⇒ area = base × height
⇒ area = 6 × 12
⇒ area = 72 square units
So, the area of the parallelogram given is 72 square units.

The area of the rectangle below is 90 cm². Form a quadratic equation involving n and solve it to find the value of n.
Answer:
2n² + 5n - 102 = 0
n = 6
Step-by-step explanation:
The formula for the area of a rectangle is:
\(\boxed{A=w \cdot l}\)
where w is the width and l is the length.
From inspection of the given rectangle:
w = (n + 4)l = (2n - 3)Given that the area of the rectangle is 90 cm², then A = 90.
Substitute the values of A, w and l into the formula:
\(\implies 90=(n+4)(2n-3)\)
Switch sides:
\(\implies (n+4)(2n-3)=90\)
Expand the left side of the equation using the FOIL method:
\(\implies 2n^2-3n+8n-12=90\)
\(\implies 2n^2+5n-12=90\)
Subtract 90 from both sides:
\(\implies 2n^2+5n-12-90=90-90\)
\(\implies 2n^2+5n-102=0\)
To solve a quadratic in the form ax² + bx + c, find two numbers that multiply to ac and sum to b.
\(\implies ac=2 \cdot (-102)=-204\)
\(\implies b=5\)
Two numbers that multiply to -204 and sum to 5 are:
17 and -12Rewrite b as the sum of these two numbers:
\(\implies 2n^2+17n-12n-102=0\)
Factor the first two terms and the last two terms separately:
\(\implies n(2n+17)-6(2n+17)=0\)
Factor out the common term (2n + 17):
\(\implies (n-6)(2n+17)=0\)
Apply the zero-product property:
\((n-6)=0 \implies n=6\)
\((2n+17)=0 \implies n=-8.5\)
n = -8.5 is an extraneous solution since this solution gives negative side lengths, which is impossible.
Therefore, the only valid value of n is n = 6.
\(\hrulefill\)
Check by substituting the found value of n:
\(\textsf{Width}=6+4=10\; \sf cm\)
\(\textsf{Length}=2(6)-3=9\; \sf cm\)
\(\textsf{Area}=10 \cdot 9=90\; \sf cm^2\)
