There are about 7 x 10^6

Step-by-step explanation:

3.5*2029249= 7102347

rounds to 7000000= 7 x 10^6

Answer:

7.102347 times [tex]10^{6}[/tex].

Step-by-step explanation:

Alright.  This is an inanely large amount of words, as a drill for scientific notation.  The first step is, since the mystery book has 2,029,242 words, to turn this into a single digit multiplied by a power of ten - 2.029242 times [tex]10^{6}[/tex] (apologies for the weird font change in the middle).  The science fiction book is 3.5 times larger - multiply 2.029242 on a calculator (unless you really like suffering for some reason; then do it by hand) - it comes out as 7.102347.  Thus, the answer is 7.102347 times [tex]10^{6}[/tex].

i need help with these

Answers

Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)

Answer:

twelve decreased by twice a number > 12 - 2x

8 times the sum of number and 4 > 8 (x + 4)

12 - 2x = 8 (x + 4)  then 12 - 2x = 8x + 32 (distributive property)

12 = 10x + 32 (add 2x to both sides)

-20 = 10x (subtract 32 from both sides)

x = -2 (divide both sides by 10)

Which expression is equivalent to (a^8)^4

A. a^2
B. a^4
C. a^12
D. a^32

Answers

Answer:

[tex]D. \ \boxed{a^{32}}[/tex]

Step-by-step explanation:

[tex](a^{8})^{4}=a^{8\cdot4}=a^{32}[/tex]

because

[tex](a^{x})^{y}=a^{x\cdot y}[/tex]

When you have two exponents and you are multiplying you have to multiply the exponents so you have to:

8*4=32


Therefore the answer is D: a^32

What is the height of the prism??

Answers

The answer would be 1.75 or 70

Answer:

3

Step-by-step explanation:

A rectangular prism has a length of 8 inches and a width of 6 inches. The lateral area is 84 square inches. What is the height of the prism?

Find the perimeter of the base.

P = 2l + 2w Perimeter of a rectangle

P = 2(8) + 2(6) Substitute: l = 8 and w = 6

P = 28

Use the formula for lateral area.

L = Ph

84 = (28)h Substitute: L = 84 and P = 28

h = 3 Solve for h.

The height of the prism is 3 inches.

a. 24 yd 2
b. 96 yd 2
c. 50 yd 2
d. 90 yd 2

Answers

Answer:

The answer is 96 yd 2

Step-by-step explanation:

First for the triangle bases, you multiply the 3 by 4 and divide by 2 to get one base which is 6, then double it to get the other base on the top to get a total of 12. Then you just find the area of the other sides of the prism by multiplying the lengths and widths.

5x7=35

4x7=28

3x7=21

then you add all of the total values together:

35+28+21+12=96
