How can a student find how much sand a sandbox can hold if it is 50 inches wide, 67 inches long, and can be filled up to 9 inches deep?
A.
use [2(50) × 2(67) × 2(9)] in3
B.
use (50 × 67 × 9) in3
C.
use (50 + 67 + 9) in3
D.
use [2(50) + 2(67) + 2(9)] in3
Answer:
B
Step-by-step explanation:
You would use the formula Length×Width×Height
In this question the length would be 67 in
The height would be 9 in
And the width would be 50 in
The unit of measure is inches
Cubed because this is a 3-dimesional shape
So the answer would be (50×67×9) in³

Beth's fitness tracker shows that she logged 4,300 steps at work today. beth wants to get
more steps in, so she goes for a jog after work. the fitness tracker shows she averages 100
steps per minute while jogging. you can use a function to approximate the total number of
steps she will have logged today after she jogs for x minutes after work.
Answer:
[tex]4300 + 100x[/tex]
Step-by-step explanation:
The [tex]4300[/tex] represents the base amount of steps she took during work. Even if she jogs 0 minutes, this will not change.
The [tex]100x[/tex] represents how many steps she will take from jogging. The [tex]100[/tex] is how many steps she will take per minute, and the [tex]x[/tex] is the number of minutes she will jog.
Adding these together will give us our function [tex]4300 + 100x[/tex] to see how many steps she will log.
That is the answer

The steps to translate the triangle ABC to A'B'C' are Shifted 3 units right and 2 units up.
The correct option is (B).
What is Coordinate Geometry?By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.
As per the given diagram:
We are given the diagram of two triangles drawn on a graph.
With the help of the graph, we can easily figure out the coordinates of each point of the triangle.
The steps to translate the triangle will be the same as that to translate any vertices of the triangle.
Let us consider A:
Coordinates of A = (2, 5)
Coordinates of A' = (5, 7)
For translating A to A':
3 units in +ve x direction. {right}
2 units in +ve y direction. {up}
Hence, The steps to translate the triangle ABC to A'B'C' are Shifted 3 units right and 2 units up.

Which measure of variability is the most appropriate for this set of values? OA range OB. interquartile range OC. mean absolute deviation OD. absolute deviation O E. either interquartile range or mean absolute deviation
The most appropriate measure is absolute deviation, as we know absolute deviation can help us gain a more representative notion of spread option (D) is correct.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
We have data shown in the picture.
As we know, Quartiles or ranges are useful, but they are limited because they skip a lot of data in the group.
For a data set like the one in this question, where the items are close in difference, absolute deviation can help us gain a more representative notion of spread.
Thus, the most appropriate measure is absolute deviation, as we know absolute deviation can help us gain a more representative notion of spread option (D) is correct.

Julianna has thirty two pieces of candy in a candy jar. Julianna only has two kinds of candy,
jolly rangers and twix. For every four twix bars, she has two pieces of jolly rangers. How many
pieces of each candy are in the candy jar?
a. The number of twix bars is 21
b. The number of jolly rangers is 11.
Julianna has thirty two pieces of candy and has four twix bars for every two jolly rangers, we need to find the ratio of candy bars.
What is the ratio of candy bars?Let
x = number of twix bars and y = number of jolly rangers.Since for every four twix bars, she has two pieces of jolly rangers, the ratio of candy bars is
x:y = 4:2 = 2:1
a. Number of twix barsThe number of twix bars is 21
The number of twix bars x = ratio of twix bars/total ratio × total number of candy bars
So, x = 2/(1 + 2) × 32
= 2/3 × 32
= 64/3
= 21.33
≅ 21
So, the number of twix bars is 21
b. Number of jolly rangersThe number of jolly rangers is 11.
The number of jolly rangers y = ratio of jolly rangers/total ratio × total number of candy bars
So, y = 1/(1 + 2) × 32
= 1/3 × 32
= 32/3
= 10.66
≅ 11
So, the number of jolly rangers is 11.
