The answers are 2460, 37,000, 3670 and 5000
Step-by-step explanation:
- Step 1: Find the answers for each by multiplying.
24.6 × 100 = 2460 (moved one decimal point)
37 × 1000 = 37,000
0.367 × 10000 = 3670 (moved three decimal points)
0.005 × 1000,000 = 5000 (moved three decimal points)
Answer:
WAIT WHAT
Step-by-step explanation:
Answer: The slope is -5x
Explanation; because it has an X next to it. the one without a variable (x) is the b value or the y-intercept.
Answer:
d. 175 square inches
Step-by-step explanation:
If we assume the base is square and all triangular faces are congruent, then the lateral area of the figure is that of four triangles. Each triangle has an area that is half the product of its base and height:
A = (1/2)bh = (1/2)(7 in)(9 in) = 31.5 in^2
The area of the square base is the product of its length and width, both of which are 7 in.
A = lw = (7 in)(7 in) = 49 in^2
So, the total surface area is that of the base plus the four sides:
surface area = (49 in^2) + 4(31.5 in^2) = 175 in^2 . . . . . matches choice D
Answer:
Volume of prism 1: 104 cubic inches
Surface area of prism 2: 650 square inches
Step-by-step explanation:
To find the volume of prism 1, set up a proportion using the side lengths and the volume of prism 2.
The ratio of the side lengths will be your scale factor. When finding volume using scale factor, you need to cube the scale factor. The numerator in the proportion are from prism 1 and the denominator is prism 2. Prism 1 is the numerator since it is the new image and we are solving for it's volume.
To find the surface area of Prism 2, we are going to setup another proportion, but this time we are going to square the scale factor since we are finding area. Prism 2 will be the numerator and prism 1 will be the denominator.
