Referring to the figure, if each block is 1 cubic unit, what is
the surface area of the rectangular prism?
a. 1/122 square units c. 84 square units
b. 61 square units d. 122 square units

Answer:

B.  14.2, 3.2

Step-by-step explanation:

diameter: 9 (count each box as 1)

d/2 = radius  --> radius: 4.5

Area of a circle= πr^2

A= 63.6172

A/r = 63.6172/4.5 = 14.1

A/r^2= 63.6172/(4.5)^2 = 3.14

Answer:

b

Step-by-step explanation:

[tex] \bf \implies {7}^{2} - 8 \times 2 - 16[/tex]

[tex]\bf \longrightarrow(7^{2} - 8)(2)- 16[/tex]

[tex]\bf \longrightarrow(49 - 8)(2) - 16[/tex]

[tex]\bf \longrightarrow(41)(2) - 16[/tex]

[tex]\bf \longrightarrow82 - 16[/tex]

[tex]\bf \longrightarrow66[/tex]

[tex]\bf \longrightarrow {7}^{2} - 8(2 - 16)[/tex]

[tex]\bf \longrightarrow49 - 8(2 - 16)[/tex]

[tex]\bf \longrightarrow49 - (8)( - 14)[/tex]

[tex]\bf \longrightarrow49 - ( - 112)[/tex]

[tex]\bf \longrightarrow161[/tex]

[tex]\bf \longrightarrow {7}^{2} - ((8)(2) - 16)[/tex]

[tex]\bf \longrightarrow49 - ((8)(2) - 16)[/tex]

[tex]\bf \longrightarrow49 - (16 - 16)[/tex]

[tex]\bf \longrightarrow49 - 0[/tex]

[tex]\bf \longrightarrow49[/tex]

[tex]\bf \longrightarrow {7}^{2} - (8)(2) - 16[/tex]

[tex]\bf \longrightarrow49 - (8)(2) - 16[/tex]

[tex]\bf \longrightarrow49 - 16 - 16[/tex]

[tex]\bf \longrightarrow49 - 32[/tex]

[tex]\bf \longrightarrow17[/tex]

Thus, Option A , Option B and Option C don't expressed the value of 17.

Therefore, The correct option is D) which expressed the value of 17.

Answer:

Well if your asking for the coordinates its obviously (-3,5) and (3,-1)

Step-by-step explanation:

just look at the lines and do x then y

Answer:

5(8-4)

Step-by-step explanation:

You need to do the subtraction first, so put it in parenthesis because otherwise subtraction comes after multiplication if you follow PEMDAS, then put a five outside to multiply it by the difference of 8 and 4.

Answer: 5 x (4-8) or 5(4-8)

Step-by-step explanation:

First, put 4-8 in brackets, because you need to do it first and without brackets you would do the multiplication first (because of BEDMAS). Then, you would multiply your subtraction by 5.

Hope this helps :)

Answer:

10

Step-by-step explanation:

We need to find out how many gallons of gas will be pumped when the total is $25 plus or minus $0.50. So what we do is $25 divided by $2.50 which will give us how many times the gas has been pumped. The answer to that is 10 which means the gas has been pumped 10 times.

Answer: 0.375

Step-by-step explanation:

Width= 1÷4= 0.25

Length= 1÷2=0.5

=(0.25x0.5)x3

=0.125x3

=0.375

Answer: v=-5/8

Step-by-step explanation:

v - 1/2 = -9/8

(v - 1/2 = -9/8)*8      ==> multiply the equation by 8 to get rid of fractions

8v - 8*1/2 = -9

8v-8/2=-9

8v-4=-9

8v=-5

v=-5/8

Answer: v=-5/8

Answer:

Rewrite 3/4 as 9/12, 9/12 is greater than 7/12, and I think they just want you to circle the fraction that aren't in the columns

Step-by-step explanation:

3 has the > sign

It's fox season! - Ash the Fox

Answer: 3 is > (greater than)

Step-by-step explanation:

Write [tex]\frac{3}{4\\}[/tex]  as   [tex]\frac{9}{12}[/tex] to make both denominators the same

How?

[tex]\frac{9}{12}[/tex]  > [tex]\frac{7}{12}[/tex],

(> means "is greater than")

If you want to just fill the blanks, here are the answers:

Just fill the blanks from left to right. The answers are:

Question #1.

12

[tex]\frac{9}{12}[/tex]

>

Question #2.

a)

[tex]\frac{9}{12}[/tex]  >    [tex]\frac{8}{12}[/tex]

so,  

[tex]\frac{3}{4\\}[/tex] > [tex]\frac{2}{3\\}[/tex]

b)

[tex]\frac{25}{40\\}[/tex] < [tex]\frac{28}{40\\}[/tex]

so,

[tex]\frac{5}{8\\}[/tex] < [tex]\frac{7}{10\\}[/tex]

Question #3.

[tex]\frac{3}{10\\}[/tex] > [tex]\frac{2}{10\\}[/tex]

How?

[tex]\frac{1 x2}{5 x2\\}[/tex]

So,

[tex]\frac{3}{10\\}[/tex] > [tex]\frac{1}{5\\}[/tex]

Step-by-step explanation:

Answer:0.125

Step-by-step explanation:

Answer:

19.28 kilometers

Step-by-step explanation:

40 percent *48.2

= (40/100)*48.2

= (40*48.2)/100

= 1928/100 = 19.28

Now we have: 40 percent of 48.2 = 19.28

Question: What is 40 percent of 48.2?

We need to determine 40% of 48.2 now and the procedure explaining it as such

Step 1: In the given case Output Value is 48.2.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 48.2 = 100%.

Step 4: In the Same way, x = 40%.

Step 5: On dividing the pair of simple equations we got the equation as under

48.2 = 100% (1).

x = 40% (2).

(48.2%)/(x%) = 100/40

Step 6: Reciprocal of both the sides results in the following equation

x%/48.2% = 40/100

Step 7: Simplifying the above obtained equation further will tell what is 40% of 48.2

x = 19.28%

Therefore, 40% of 48.2 is 19.28
