A tabletop in the shape of a trapezoid has an area of 5,550 square centimeters. Its longer base measures 115 centimeters, and the shorter base is 85 centimeters . What is the height?
Answer:
55.5 cm
Step-by-step explanation:
[tex]h=2*\frac{A}{a+b} \\\\h=2*\frac{5550}{115+85} \\\\h=2*\frac{5550}{200} \\\\h=2*\frac{111}{4} \\\\h=55.5[/tex]

Determine which of the transformations applied to Circle A could be used to prove Circle A is similar to Circle B. Select Yes or No for each transformations.
THE ANSWER I PUT WAS WRONG!!!
Answer:
Step-by-step explanation:
Circle A has center (-2, 3)
Circle B has center (2, -2)
Circle A can be mapped to Circle A' by a translation:
Center Rule of translation New center
(x, y) (x+4, y-5)
A(-2, 3) A'(-2+4, 3-5) A'(2, -2)
Circle A with radius r 1=2
Circle B with radius r 2=3
Scale factor= r 2/r 1 = 3/2 = 1.5
Since any two circles can be translated to have the same center, the dilation r2/r1 proves the circles are similar where r1 and r2 are the radii of the circles.
The Circle A' and circle B both have center (2, -2). Then circle A' can be mapped to circle B by a dilation with center (2, -2) and a scale factor 3/2=1.5. So circle A and circle B are similar.
Therefore: Translation right 4, down 5, and then a dilation of 1.5 is true.
Translation down 5, right 4, and then a dilation of 1.5 is true.

Sylvie needs $110 for a concert ticket. She already has $16 and she can earn the rest by working 10 hours at her job. If h represents her hourly earnings, which of the following equations can be solved to find Sylvie’s hourly earnings? Select all that apply
A 110 - 16 = 10h
B 110 = 16h + 10
C 16 = 110 - h
D 110 = 16 + 10h
E 110 + 16 = 10h
Answer:
Option A and D
Hope this helps!
Answer:
D
Step-by-step explanation:
16 +10h = 110 is the equation because it uses 10h to represent the hourly wages and you need $110. Therefore, with the starting $16, if you use the hourly $10 rate you can come to your answer using the equation.
At the start of a party, a drink dispenser contains 9 1.2 quarts of iced tea. After the party only 7 cups of tea remain. How many cups of iced tea did people drink during the party?
Answer: 31 cups
Step-by-step explanation:
We should note that 1 quarts = 4 cups
Therefore, 9 1/2 quarts = 9 1/2 × 4 = 19/2 × 4 = 38 cups
Since only 7 cups of tea remained.after the party, the number of cups of iced tea that the people drank during the party will be:
= 38 - 7
= 31 cups of iced tea
A circular garden has a circumference of 50 yards. Lars is digging a straight line along a diameter of the garden at a rate of 4 yards per hour. How many hours will it take him to dig across the garden? Use 3.14 for π and round the diameter to the nearest whole number, if necessary.
Answer:
8
Step-by-step explanation:
The first step is to calculate the radius
r= C/2π
= 50/2×3.142
= 50/6.284
= 7.96
Hence the diameter to the nearest whole number is 8
Rick is currently 72 inches tall. He wants to compare himself to his friend who is 5 feet and 11 inches tall. How many inches taller is Rick than his friend?
Answer:
1 inch
Step-by-step explanation:
We would have to convert rick's friends height to inches
1 feet = 12 inches
Friend's height = (12 x 5) + 11 = 71 inches
Difference in height = 72 - 71 = 1

If we plug in the values for A and B we get 9(1/3^2)+3(5)-10. Then using simple math and order of operations, we get 6.
write the equation of the line in slope intercept form given a table
Answer:
y=3x+1
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y intercept
the formula for slope (m) is given as (y2-y1)/(x2-x1)
we can pick any 2 points to use to find the slope. For example, let's use (2,7) and (3,10)
label the points:
x1=2
y1=7
x2=3
y2=10
now substitute into the formula:
m=(y2-y1)/(x2-x1)
m=(10-7)/(3-2)
m=3/1
m=3
the slope of the line is 3
here's our equation so far:
y=3x+b
now we need to find b (y intercept)
because the line will pass through any of the points given on the table, we can use any one of the given points to solve for b
Let's take (2,7) though since it's the first point
substitute 2 as x and 7 as y in the equation
7=3(2)+b
7=6+b
1=b
so our equation is y=3x+1

Janet has a 65 dollar budget to buy paper goods and plastic cutlery for an impromptu birthday party. She determines that the paper goods will cost 37.50 . How many sets of cutlery can she purchase if each set costs 0.75? (She cannot buy a partial set of cutlery.)
Janet can buy 36 sets of cutlery.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Janet has a 65 dollar budget to buy paper goods and plastic cutlery for an impromptu birthday party
the paper goods will cost 37.50
We need to find the difference of 65 dollars and 37.50 to determine the amount left to purchase cutlery
65-37.5
27.5
As by given, each cutlery set costs 0.75.
We need to divide 27.5 by 0.75 to find number of cutlery sets
27.5/0.75=36.6
Hence, Janet can buy 36 sets of cutlery.
