Answer:
a- 30
b- 90
Step-by-step explanation:
150 learn math
120 learn english
150+120 is 270
270 - 240 = 30
so 30 students learn both.
120 - 30 = 90
so 90 learn english only

How far the penguin can walk in 1 second
Not known. This varies because it depends on if the penguin is going full speed or not, and the size or even just the penguin itself because not all penguins walk the same speed.

Answer:
34.61Step-by-step explanation:
Find the diagram attached
From the diagram;
Hypotenuse = 81.9
Angle of elevation = 65degrees
Required
The value of x (Adjacent)
Using the SOH CAH TOA identity
cos theta = adjacent/Hypotenuse
cos 65 = x/81.9
x = 81.9cos65
x = 81.9(0.4226)
x = 34.61
Hence the value of x to the nearest hundredth is 34.61

The lenths of the 2 legs of right triangle abc show below are given in inches. The midpoint of ab is how many inches from A ?
Answer:
Option B
Step-by-step explanation:
The complete question is attached
As we can see in the image , ABC is a right angle triangle
Thus as per Pythagorean theorem, to find line AB
AB2 = 322 + 242
AB2 = 1024 + 576
AB2 = 1600
Taking square root of both the sides, we get –
AB = √1600
AB = 40
The mid point of AB = AB/2 = 40/2 = 20
At a pet store, there are 30 aquariums.
Of the 30, 20 have fresh water with
15 fish each. The other 10 aquariums
have salt water with 6 fish each. Which
equation could be used to find f, the
total number of fish at the pet store?
Answer:
f = (20 × 15) + (10 × 6)
Explanation:
You are just find how many fish are salt water and how many freshwater and adding them together. The total number of aquariums is irrelevant in this case.

Answer:
5x - 68 = x
Step-by-step explanation:
number = x
5x - 68 = x
Solve for x:
5x - 68 = x
-68 = x - 5x
-68 = -4x
68 = 4x
x = 68/4
x = 17
Answer:
55x-68 = x

Annabel is comparing the distances that two electric cars can travel after the battery is fully charged. Car A (miles) Car B (miles) Mean 145 200 Median 142 196 IQR 8 4 MAD 6 2 Part A Use the measures of center to make an inference about the data. Use the drop-down menus to complete your answer. Car A can travel further than Car B after the battery is fully charged. Part B Based on the data, which car performs most consistently? Explain. A. Car A because the measures of center are smaller for Car A than for Car B. B. Car B because the measures of center are smaller for Car B than for Car A. C. Car A because the measures of variability are smaller for Car A than for Car B. D. Car B because the measures of variability are smaller for Car B than for Car A.
Answer:
Car B can travel further than Car A after the battery is fully charged.
D. Car B because the measures of variability are smaller for Car B than for Car A.
Step-by-step explanation:
Car B can travel further than Car A after the battery is fully charged because Car A has lesser mean and median than Car B.
Median divides the data into two halves. A smaller median means that there is lesser mileage of Car A than Car B.
There are two measures.
Measure of center tells us how much near or far the data is spread from the center.
The mean , median and mode are the measures of center.
Car A has less mean , median telling us that it traveled less.
Measure of Variability tells us how data changes with a single value.
Smaller MAD means the data is denser at the mean. Car B has lesser MAD.
Smaller IQR tells us that data is closer to the middle of the data.
Car B has smaller IQR .
So car B traveled consistently as it has smaller IQR and MAD
D. Car B because the measures of variability are smaller for Car B than for Car A.
Answer:
Car B can travel further than Car A after the battery is fully charged.
D: Car B because the measure of variability is smaller for Car B than for Car A.

if a triangle is dilated with a scale factor of 3, how do the sizes for the pre-image and image compare?
Answer:
Please check explanations
Step-by-step explanation:
When we dilate a particular figure, we are simply increasing the dimensions of its sides
By dilating the pre-image by a factor of 3, we are simply increasing the dimensions of it by a multiple of 3
so say for example, the base of the pre-image has a measure of 4 ft, the base of the image which is the pre-image dilated by a scale factor of 3 will be 4 ft * 3 = 12 ft
What this mean is that we have succeeded in tripling the dimension of the pre-image to give the dimension of the image

Find the perimeter of the object
Help step by step please!
Answer:
29.42 units
Step-by-step explanation:
1) Find the perimeter around the semi-circle
To do this, we find the circumference of the circle using the given diameter:
[tex]C=\pi d[/tex] where d is the diameter
Plug in 6 as the diameter
[tex]C=\pi (6)\\C=6\pi[/tex]
Divide the circumference by 2
[tex]\frac{6\pi }{2} \\= 3\pi[/tex]
Therefore, the perimeter around the semi-circle is 3π units.
2) Find the perimeter around the rest of the shape
Although it's impossible to determine the lengths of the varied sides on the right side of the shape, we know that all of those vertical sides facing the right add up to 6. We also know that all of those horizontal sides facing up add up to 7. Please refer to the attached images.
Therefore, we add the following:
7+6+7
= 20
Therefore, the perimeter around that area of the shape is 20 units.
3) Add the perimeter around the semi-circle and the perimeter around the rest of the shape
[tex]20+3\pi \\= 20+9.42\\= 29.42[/tex]
Therefore, the perimeter of the shape is approximately 29.42 units.
I hope this helps!

An experiment was conducted by some students to explore the nature of the relationship between a person's heart rate (measured in beats per minute) and the frequency at which that person stepped up and down on steps of various heights. Three rates of stepping and two different step heights were used. A subject performed the activity (stepping at one of the three stepping rates at one of the two possible heights) for three minutes. Heart rate was then measured at the end of this period. The variables "stepping rate" and "step height" are the
A. factors.
B. levels.
C. controls.
D. units.
E. response variables.
Answer:
A. factors.
Step-by-step explanation:
The correct option is - A. factors.
Reason -
The variables "stepping rate" and "step height" are the factors because a activity is performed in which stepping at one of the three stepping rates at one of the two possible heights for three minutes.
The activity is based on both the variables stepping rate and step height.
