i tried 7 and it didn't work
so i used a hint - it's 6!
6 pies are more in 60 to 89 cherries than 90 to 119 cherries, a bar graph is a graphical depiction of information, amounts, or numbers using bars or strips.
What is the bar graph?They are employed to contrast and compare various data kinds, frequencies, or other measurements of several categories of data.
here, we have,
The calculation of the bar graph in the given question.
For 60 - 89 cherries there are 10 pies
For 90 -119 cherries there are 4 pies
10 -4 = 6 pies
The image for the graph is attached below.
When displaying sections of data, bar charts should be used. As long as there aren't too many categories to compare, vertical bar charts can be useful for comparing several categories or discrete data, such as age groups, classes, schools, etc. They are quite helpful for time series data as well.
Therefore, there are 6 more pies in the 60 -89 cherries category than in the 90-119 category.

HELPP 10 POINTS Here's a graph of a linear function. Write the equation that describes that function.
Answers
Answer:
y = (3/2)x+1
Step-by-step explanation:
Slope intercept form is y=mx+b where m represents the slope and b represents the y-intercept. As we can see on this graph, the line intersects the y axis at (0,1). Therefore, the y-intercept is 1. Now, we can choose another point to find the slope. I'll choose (2,4). To reach (2,4) from the y-intercept, we have to go up 3 units and right 2 units. Therefore, the slope is 3/2.
Our equation of the line is: y = (3/2)x+1
Write the equation that describes that function.
Answer:
y = (3/2)x+1

3 equal angles
so the triangle is equilateral => 3 equal sides
4x-10 = 3x+2
x = 12
or
4x-10 = 5x-22
-x = -12
x = 12
or
5x - 22 = 3x + 2
2x = 24
x = 12
x = 12
Answer:
The value of x = 12
Step-by-step explanation:
This is an equilateral triangle and the sides of an equilateral triangle are equal .
By putting the two sides of the triangle equal , we can find out the value of x
=> 4x - 10 = 3x +2
=> 4x - 3x = 2 + 10
=> x = 12

Step-by-step explanation:
By using PGT

=> 5² +x² +2(5)(x) = 49+x²
=> 25 + x² + 10x = 49 +x²

Store A sells a watch for $50 and offers a 5% discount. Store B sells
a
the same watch for $60 and offers a 20% discount. From which store
should you buy, and why?
O Store B, $4.00 cheaper
O Store B, $9.50 cheaper
O Store A, $0.50 cheaper
O Store A, $9.50 cheaper
Answers
Answer:
(c) Store A, $0.50 cheaper
Step-by-step explanation:
When a price is discounted by a rate d, the multiplier of the price is (1 -d).
Store AThe discounted price is $50 × (1 -0.05) = $50×0.95 = $47.50
__
Store BThe discounted price is $60 × (1 -0.20) = $60×0.80 = $48.00
__
The price at Store A is less by ...
$48.00 -47.50 = $0.50
shop = 5 ÷ 100 × 50 = 2.5
shop = 20 - 60 × 100 = 12
shop = $50 - 2.5 = $ 47.5
Shop = $60 - 12 = $48
then, we have to minus $48 .00 with $ 47.50 we get :-= $48 .00 - $ 47.50 = $0.50
Store A, $0.50 cheaper-8(-2-7r)=-208

Answers
Answer:
x=6
Step-by-step explanation:
6(2x -11) 15 =21
6 × 2x = 12x
6 × -11 = -66
12x -66 + 15 = 21
-66 + 15 = -51
12x -51 = 21
-51 + 51 = 0
21 + 51 = 72
12x = 72
12x ÷ 2 = 0
72 ÷ 12 = 6
