Decide which of the following is a reasonable answer for 3/7 x8

Answer: x^2+5

Step-by-step explanation:

x is the unknown variable which is representing the number squared and then you add 5 to complete expresssion.

Answer:

x² + 5

Step-by-step explanation:

Given statement:

We know the following:

    1. "number squared" ⇒ A number multiplied to the same number.

    Let the number be known as "x". Then;

        [tex]\implies x \times x[/tex]

        [tex]\implies \underline{x^{2}}[/tex]

   2. "added to 5" ⇒ Addition between number, squared and 5.

   Let the number be known as "x". Then;

        [tex]\implies (x)^{2} + 5[/tex]  [tex](\text{number, squared} \implies x^{2} )[/tex]

        [tex]\implies \boxed{x^{2} + 5}[/tex]

Therefore, the expression that represents the statement is x² + 5.

Answer:

I believe it's the first one

Answer:

The First one and the third one

Step-by-step explanation:

All you have to do is the distributive property and multiply 7 times 3x and 7 times 2 to get 21x + 14. Then you add like terms for the third one and get x2+5.

Answer:

the MAD to this set is 6.75

Step-by-step explanation:

The process is pretty long on how to find the MAD but here it goes.First you find the mean of the set( 70 )then you find the distances between all the numbers and the mean( 68 is 2 values away from being 70 so that would be 2) than you add all the distances together than divide that number by the amount of values are in the set.

hope that makes sense have a good day

Answer:

199.51$

Step-by-step explanation:

10 x 12 = 120$

25 x 5 = 125$

5 x 8 = 40¢

1 x 11 = 11¢

30 + 50 = 80$

120$ + 125$ + 40¢ + 11¢ + 80$ = 325.51$

325.51$ - 44$ = 281.51$ - 25$ = 256.51$ - 12$ = 244.51$ - 15$ = 229.51$ - 30$ = 199.51$

Answer:

V≈83.78

Step-by-step explanation:

The formula to find the volume of a cone is V=πr(squared) h/3

Steps

V= π (4)^2  5/3

V= π (16)  1.66666666667

V = 50.2654824574 * 1.66666666667

v= 83.7758040958

Round

V = 83.78

Answer:

The volume of cone is 83.73m³.

Step-by-step explanation:

To find the volume of the cone we use Formula:

[tex] \sf V = \frac{1}{3} \pi {r}^{2} h \\ \\ \implies \: \frac{1}{3} \times 3.14 \times {4}^{2} \times 5 \\ \\ \implies \frac{1}{3} \times 15.70\times 16 \\ \\ \implies \: \frac{1}{ \cancel3} \times \cancel{251.20} \\ \\ \implies \sf \pink{83.73 {m}^{3} }[/tex]

Hence, the volume of cone is 83.73m³.

Answer:

  (b)  y = 4x +15; y = 10x -2

Step-by-step explanation:

It is often sufficient to check for reasonableness in the offered answers. That is the case here.

__

The offered answer choices differ in the combinations of slope. The offered slopes (x-coefficients) are 4 or 1/4, 10 or 1/10, so it is sufficient to determine if the slope is greater than 1 in each case.

The slope is the ratio of the change in y to the change in x. It will be greater than 1 if y changes by a larger number than x does.

x-values in this table change by 4-2 = 2. y-values change by 31 -23 = 8, which is more than 2. The slope is greater than 1 for the first equation. (It is 8/2 = 4.)

The first two x-values in this table differ by 0-(-1) = 1. The first two y-values differ by -2-(-12) = 10, which is more than 1. The slope is also greater than 1 for the second equation. (It is 10/1 = 10.)

The x-coefficients in the answer choices are ...

  a) 1/14, 1/10 . . . incorrect

  b) 4, 10 . . . . correct

  c) 1/4, 10 . . . . partly correct

  d) 4, 1/10 . . . . partly correct

Answer:

mode = 88

Step-by-step explanation:

Answer:

84 months

Step-by-step explanation:

Maria is 7 years old, there are 12 months in a year, multiply 12 by 7.

12 * 7 = 84

Maria is 84 months old

Answer:

Maria is 84 months old.

Multiply the years(y) by every 12 months that pass(m).

[tex]y * m = 84[/tex]

note that y is 7, and m is 12, because we count every 12 months that pass for 7 years.

A and C are congruent.

Step-by-step explanation:

Answer:

The trapezoids and the irregular figures at the top left.

Step-by-step explanation:

Congruent means "in agreement or harmony." So that means in math congruent means "the same" and the trapeziods were both the same and so were the irregular figures.
