D. When you do the math, the results to everything should be t=9. D is the only outlier. Therefore, D is the answer in this case.
First you must find the scale.
Divide 4 by 0.8.
You get 5.
Divide 7 by 1.4.
That also gives you 5.
This means the scale drawing is 5 times smaller than the real dimensions.
On the scale drawing, the kitchen is 2.4 by 2.8 inches.
All you have to do is multiply both of these by 5 and change it to feet.
2.4 x 5 = 12
2.8 x 5 = 14
So the dimensions of the kitchen are 12 feet by 14 feet.
Solve using the foil method (first, outside, inside, last).
(m + 5)(m - 3)
Your steps using foil should look like:
- m * m
- m * -3
- 5 * m
- 5 * -3
After multiplying, rewrite your expression.
m² - 3m + 5m - 15
The last step to simplifying this expression is to combine like terms, which are -3m + 5m.
<h3>m² + 2m - 15</h3>
Answer:
1) 59.7 2) 7.1
Step-by-step explanation:
1)The diameter of a circle is 19 m. Find the circumference to the nearest tenth
The equation to find the circumference for a circle is C=2πR or C = πD. The diameter is equal to 2r so that is why the equation works either way. Now we will plug in the numbers. C =19π. This is approximately equal to 59.6902604182 which is approximately equal to 59.7
2)AND the diameter of a circle is 3ft. Find its area to the nearest tenth.
As stated before the diameter is equal to 2r. The area of a circle is calculated using the equation πr^2. First we need to find the radius which is 1/2D. 3/2 = r or 1.5 = r. Now we can plug all values in. A = π1.5^2 which equals to 2.25π which equals to 7.06858347058 which is approximately 7.1.
