Answer:
9 inches
Step-by-step explanation:
Perimeter of equilateral triangle = 3x
Perimeter of square = 4x
3(x + 6) = 9 + 4x
3x + 18 = 9 + 4x
-x = -9
x = 9

find the corret measure of 6
Answer:
∠3 = 102°
Step-by-step explanation:
║A straight line always equals 180°. So all we need to do is subtract 78° ║from 180° for the missing angle.
180 − 78 = 102
∠3 = 102°
Further explanation:
║The image shows two slanted lines across one vertical line. If we visualize ║a circle around the point where the slanted line intercepts with the vertical ║line, we can solve this.
[we only need one line to work with, because both lines are parallel]
║That circle you visualized divides the intercept into four sectors. One of ║those sectors, or angles, is labled 78°. We need to find the angle measure ║underneath the labled sector. The sector in the bottom right corner has ║the same angle measure as the labled sector, which is 78°. The sector ║labled ∠3 has the same angle measure as the sector in the upper right.
[a full rotation around an angle is always 360°]
║This can be easily solved by subtracting 78° from 180° to get the angle ║measure for the upper right sector, which is equivalent to ∠3. Using basic ║subtraction, 180° − 78° = 102°. We can prove this by multiplying 78° by 2, ║multiplying 102° by two, and adding the products.
78 ⋅ 2 = 156
102 ⋅ 2 = 204
204 + 156 = 360
║Because the sums equal 360°, we can determine the answer is true.

What is 50% of 40
Thank you
Answer:
20
50% of 40 is 20 because half of 40 is 20
Answer:
20
Step-by-step explanation:
1) Change 50% into a decimal
50% ⇒ 0.5
2) Multiply 0.5 by 40
0.5 × 40 = 20
Therefore, 50% of 40 is 20.

Which best explains why an iceberg floats? Water expands and becomes denser when it freezes. Water contracts and becomes denser when it freezes. Water expands and becomes less dense when it freezes. Water contracts and becomes less dense when it freezes.
Answer: Water expands and becomes less dense when it freezes.
Step-by-step explanation:
When a solid is less dense than liquid that it is put in, it will float.
This is the case with icebergs. When water freezes, the molecules move away thereby expanding and increasing the volume of the water.
The larger the volume of an object, the smaller it's density.
The iceberg will therefore have a lower density that enables it to float.
Answer:
C: Water expands and becomes less dense when it freezes.

A manufacturer is considering building a new and better mousetrap. She estimates the probability that the new mousetrap will be successful is . If it is successful, it would be able to make $120,000. Of course, she would make nothing if it were unsuccessful. The development costs for the mousetrap are $98,000. What is the expected value?
8,000
-$8,000
$22,000
-$32,000
Answer:
$22,000
Step-by-step explanation:
Subtract the development cost from the amount it would make.
And boy, that's one expensive mousetrap.

When rounding to the nearest hundred thousand, the weight of a blue whale was rounded to 500,000 pounds. What is the least the blue whale could actually weigh?
Answer:
450,000 pounds
Step-by-step explanation:
to round off to the nearest hundred thousand, look at thousand figure - If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
to be rounded off to 500,000, it means that the thousand figure has to be between 50,000 - 99,000
the least figure would thus be 450,000

The $24.75 is the sale price after reducing the original price by 10%.
Calculate the original price
Answer: $ 27.50
Step-by-step explanation:
We know that $24.75 is (100%-10%) = 90% of the original price.
24.75/90 = 0.275 (to find one percent)
0.275 x 100 = 27.5 (100%, the original price)

You rent an apartment that costs $1200 per month during the first year, but the rent
is set to go up 12% per year. Write a recursive formula to show what the rent is during
the nth year of living in the apartment.
Answer:
So first we have to figure out what $1200 per month for 12 months is since it was a year. 1200x12=14,400 a year which is outrageous for an apartment just saying.
Then we find out what 12% of the 1200 is and then add it to 1200.
To find the percentage of that we need to know how many times 12 fits into 100% 12 fits into 100 a total of 8.33333333333 times.
So now we divide 1200 by 8.33333333333 to see what 12% of it is.
1200 divided by 8.33333333333 is 144. So 1200+144=1344.
Now since one of the nine years has passed already we only have 8 remaining.
Now we see what 1344 a month for 12 months is 16,128 a year.
Now we multiply 16,128 by 8 to get the outcome of 8 more years. So 16,128x8=129,024
