64° + 76° + (2x+14)° = 180° (angle sum of triangle)
140° + 2x+14° = 180°
2x=180 ° - 14 ° -140°
2x=26°
x=13°
Answer:
x = 13
Step-by-step explanation:
the sum of the triangle angles always adds up to 180 degrees, otherwise it is not a triangle.
64 + 76 = 140
180 - 140 = 40.
therefore, the last angle must equal 40 degrees.
2 * x + 14 is the equation we need to us to get to 40 degrees.
40 - 14 = 26
26 / 2 = 13
therefore, x equals 13
now, is we want to check our answer to make sure it is correct,
2 * 13 + 14 = 26 + 14
26 + 14 = 40
76 + 64 = 140
180 - 140 = 40
therefore, it works.
good luck my friend!

Last month I had 8 guppies. This month I have 20 guppies. What is the percent of increase in guppies from last month to this month?
Answer: 150% increase
Step-by-step explanation:
percent of increase: new/old × 100%-100%
--------------
new/this month: 20 puppies
old/last month: 8 puppies
new/old×100%-100%
=20/8×100%-100%
=2.5×100%-100%
=250% -100%
=150% increase

Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30

Which ordered pair is the solution to the system of equations? {x+2y=−8y=12x−2
Answer:
\(\left( -\dfrac{4}{25}, -\dfrac{98}{25} \right)\)
Step-by-step explanation:
\(x+2y=-8 \\\\y=12x-2\)
Substitute:
\(x+2(12x-2)=-8\)
Expand:
\(x+24x-4=-8\)
Simplify:
\(25x=-4\)
Divide both sides by 25:
\(x=-\dfrac{4}{25}\)
Plug this back into one of the original equations to find y:
\(-\dfrac{4}{25}+2y=-8 \\\\\\2y=-7 \dfrac{21}{25}=-\dfrac{196}{25} \\\\\\y=-\dfrac{98}{25}\)
The ordered pair that represents this solution is therefore:
\(\left( -\dfrac{4}{25}, -\dfrac{98}{25} \right)\)
Hope this helps!

= 9/4 ÷ (3/8 × 2/1)
= 9/4 ÷ (6/8)
= 9/4 ÷ (3/4)
=9/4 × 4/3

48 cm : 56 cm as a fraction in simplest form
Answer: 6:7
Step-by-step explanation:
48:56
DIVIDE BY 8 ON BOTH SIDES
6:7
Answer:
6/7
Step-by-step explanation:
To express 48 cm : 56 cm as a fraction in simplest form, we need to find the greatest common factor (GCF) of 48 and 56 and divide both terms by it.
The prime factorization of 48 is 2 x 2 x 2 x 2 x 3, and the prime factorization of 56 is 2 x 2 x 2 x 7.
The GCF of 48 and 56 is 2 x 2 x 2, which is 8.
Therefore, we can simplify 48 cm : 56 cm as:
48 cm : 56 cm = (48/8) cm : (56/8) cm = 6 cm : 7 cm
So, 48 cm : 56 cm as a fraction in simplest form is 6/7.

What is the volume, in cubic inches, of a cone that has a radius of 9 inches and a height of 16 inches? Use 3.14 for π (pi), and round to the nearest hundredth.
Answer:
The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.
Substituting the given values, we get:
V = (1/3) x 3.14 x 9^2 x 16
Calculating this expression gives us:
V = 1810.08 cubic inches
Rounding to the nearest hundredth gives us:
V ≈ 1810.08 cubic inches (rounded to two decimal places)
Therefore, the volume of the cone is approximately 1810.08 cubic inches.
Answer:
1363.04
Step-by-step explanation:
V = (1/3) * 3.14 * 9^2 * 16
Simplifying:
V ≈ 1363.04 cubic inches
Which figure has exactly one line of symmetry? A rhombus, pentagon, rectangle and triangle are shown. A. Rhombus B. Pentagon C. Rectangle D. Triangle
Answer: The figure that has exactly one line of symmetry is B. Pentagon.
Step-by-step explanation: A line of symmetry is a line that divides a figure into two congruent halves that are mirror images of each other. A figure can have zero, one, or more lines of symmetry depending on its shape and orientation. To find the lines of symmetry of a figure, we can use a paper folding method or a reflection test. A paper folding method involves folding the figure along a line and checking if the two halves match up exactly. A reflection test involves reflecting the figure over a line and checking if the image coincides with the original figure.
Using either method, we can see that:
A. Rhombus has two lines of symmetry: one diagonal and one vertical.
C. Rectangle has two lines of symmetry: one horizontal and one vertical.
D. Triangle has either zero or three lines of symmetry depending on the type of triangle. An equilateral triangle has three lines of symmetry: one vertical and two bisecting the angles. An isosceles triangle has one line of symmetry: the perpendicular bisector of the base. A scalene triangle has no lines of symmetry.
B. Pentagon has either zero or five lines of symmetry depending on the type of pentagon. A regular pentagon has five lines of symmetry: each passing through a vertex and the midpoint of the opposite side. An irregular pentagon has no lines of symmetry.
Therefore, the only figure that has exactly one line of symmetry is B. Pentagon, but only if it is an isosceles pentagon.

Every day, Ed's orange juice stand uses 2/3 of a bag of oranges. How many days will 2 2/3 bags of oranges last?
Answer:
4 days
Step-by-step explanation:
2 2/3 ÷ 2/3
2 2/3 = \(\frac{3}{3}\) + \(\frac{3}{3}\) + \(\frac{2}{3}\) = \(\frac{8}{3}\) (\(\frac{3}{3}\) is another name for 1)
\(\frac{8}{3}\) ÷ \(\frac{2}{3}\) = \(\frac{4}{1}\) = 4

the ratio of males to females at a camp is 5 to 4. If there are 40 males at the camp, how many females are there?
Answer:
5 males : 4 females
40 males : X females
5/40 =4/X
(cross multiplication)
5x = 4*40
5x = 160
(divide both sides by 5)
X = 32
therefore, there are 32 females at the camp

On Monday April 1, Michelle collected 6 seashells. She collected 6 more each day until the end of the month. Her friend Karen collected 8 seashells on April 1 and 8 more shells each day until the end of the month. what is the first date they will have collected the same number of shells?
Answer: April 4th
Step-by-step explanation: Make multiples of each number. 6, 12, 18, 24 then 8,16,24. both numbers meet at 24, but Michelle simply takes longer. Since Michelle collects 6 every day and 6x4 =24, the answer is April 4th

Answer:
9m-8
Step-by-step explanation:
you need to group like terms and solve
Answer:
9m - 8
Step-by-step explanation:
We know that,
( - ) × ( - ) = ( + )
( + ) × ( + ) = ( + )
( - ) × ( + ) = ( - )
Accordingly, let us solve it now.
10m + ( – 8 ) + 9m + ( – 10m )
Solve the brackets.
10m - 8 + 9m - 10m
Combine like terms.
