Tory sold 50 balloons for School Spirit Day. He raised $37.50. He wrote this equation to show how much he charged for each balloon.
= 37.50
What mistake did Tory make in writing his equation? What is a correct equation and its solution?
A. He divided b by 50 instead of by 37.50. A correct equation is = 50. Its solution is $1,875.
B. He divided b by 50 instead of dividing 50 by b. A correct equation is = 37.50. Its solution is $1.33.
C. He divided b by 50 instead of multiplying b by 50.A correct equation is 50b = 37.50. Its solution is $0.75.
D. He divided b by 50 instead of setting up a proportion. A correct equation is = . Its solution is $1,875.
Answers
Answer:
Answer is C $0.75
Step-by-step explanation:
50b = 37.50
divide both sides by 50
50 cancels out b is by itself.
37.50 divide by 50= 0.75
The mistake Tory made is he divided b by 50 instead of multiplying b by 50. A correct equation is 50b = 37.50. Its solution is $0.75.
What does division mean?Division is a mathematical operation that involves the grouping of a number into equal parts using another number. The sign used to denote division is ÷.
The equation that represents the total amount raised: total balloons sold x cost of one balloon
b x 50 = 37.50
b = 37.50/ 5-
b = $0.75

Step-by-step explanation:
[tex]\frac{5}{3}= \frac{20}{y}[/tex]
Cross multiply.
5 × y = 3 × 20
5y = 60
5y ÷ 5 = 60 ÷ 5
y = 12
The width is 12 cm. Moving onto the time.
[tex]\frac{12}{4} =\frac{y}{1}[/tex]
Cross multiply.
4 × y = 12 × 1
4y = 12
4y ÷ 4 = 12 ÷ 4

Answer:
A) 26°
Step-by-step explanation:
The angle x decreases at a rate that is 12 times the rate of increase of angle y.
x = 360 -12y
We want x = 2y, so ...
2y = 360 -12y
14y = 360
y = 360/14 ≈ 25.71 ≈ 26
The integer angle closest to y is 26°.

increase in inches of snow from 2020 to 2021?
Answers
To find the answer, you need to subtract the total inches of snow in 2021 by the total inches of snow in 2020.
So 38 -20= 18
Therefore, from 2020 to 2021. The snow increased by 18 inches.

Foresters want to estimate the average age of trees in a stand. Determining age is cumbersome, because one needs to count the tree rings on a core taken from the tree. In general, though, the older the tree, the larger the diameter, and diameter is easy to measure. The foresters measure the diameter of all 1132 trees and find that the population mean equals 10.3. They then randomly select 20 trees for age measurement
Answers
Answer:
hello your question has some missing information attached below is the missing information
answer : mean ratio of estimate = 117.62
standard error ( SE ) = 3.9765
Step-by-step explanation:
Given data : n = 20, μx = 10.3 , N = 1132
∑ age ( yi) = ( 125 + 119 + --------- + 99 ) = 2148
∑ ( Y - rX)^2 = 6116.728
mean of age ( y ) = ∑ y / 20 = 2148 / 20 = 107.4
mean of diameter ( x ) = ∑x /20 = 188.1 / 20 = 9.405
∴ ratio estimate = y /x = 107.4 / 9.41 = 11.4195
i) The mean of ratio estimate
= 11.4195 * μx = 11.4195 * 10.3 = 117.6204
ii) determine the standard error ( SE )
calculate ; [tex]s^{2} _{r}[/tex] = 1 / ( n-1 ) * ∑ (Y - rX)^2 = 1/19 ( 6116.728 ) = 321.933
Var ( μr ) = [ ( N - n ) / N*n ]*[tex]s^{2} _{r}[/tex] = [ ( 1132 - 20 ) / (1132*20) ] * 321.933
= 15.81226
therefore the SE = √15.81226 ≈ 3.9765
