Answer:

[tex]65s = 390[/tex]

Step-by-step explanation:

Given

[tex]Books = 390[/tex]

[tex]Shelf = 65[/tex]

Required

Write an expression for the scenario

1 shelf can hold 65 books.

s shelves can hold 65s books.

So:

[tex]s\ shelves - 390[/tex]

Substitute 390 for s shelf

[tex]65s = 390[/tex]

Answer:

-3

Step-by-step explanation:

3x+(2-4x)

3*5+(2-4*5)

15-18

-3

To solve this problem you must apply the proccedure shown below:

1. You have the the 13.5​-m fire truck ladder is leaning against a wall and the ladder makes an angle of 39 degrees 45 ' with the horizontal.

2. Then you have:

39 degrees 45'=39.75°

Sin(39.75°)=d/13.5

d=13.5xSin(39.75°)

d=8.63

Answer:

The correct answer is given by option a.

Step-by-step explanation:

Rational roots theorem:

In the rational roots theorem, we take the leading coefficient(which multiplies the term of x with the highest exponent) and the independent term(which does not multiply any value of x).

The possible roots have the format p/q, in which p are the factors of the independent term, and q are the factors of the leading coefficient.

In this question:

Leading coefficient: 3

Independent term: 15

Factors of the independent term: {1, 3, 5, 15} -> p

Factors of the leading coefficient: {1,3} -> q

Possible roots:

All possible values, positive or negative, in which p is divided by q. So

[tex]\pm \frac{1}{1}, \pm \frac{1}{3}, \pm \frac{3}{1}, \pm \frac{3}{3}, \pm \frac{5}{1}, \pm \frac{5}{3}, \pm \frac{15}{1}, \pm \frac{15}{3}[/tex]

So, without the repeated terms, they are:

[tex]\pm \frac{1}{3}, \pm \frac{5}{3}, \pm 1, \pm 3, \pm 5, \pm 15[/tex]

The correct answer is given by option a.

Answer:

Step-by-step explanation:

There are multiple solutions.

If each section has n seats, the floor has 22,180-85n seats.

22,180/85 ≅ 260.9, so each section has at most 260 seats.

If each section has 260 seats, the floor has 22,180-85×260 = 80.

what is the approximate square root to 115

10.7

Step-by-step explanation:

this is the ans

20

160/8=20

88/8=11

i hope this one helps !!

Answer:

20,020 in. on the plans

Step-by-step explanation:

To get from 11 in. to 88 in. (from plans to real life), you multiply by 8.

Therefore, to get from 160,160 to ?? (from real-life to plans), you would divide by 8.

160,160 / 8 = 20,020

To check, you can multiply 20,020 by 8 to go from plans to real-life measurements; 20,020 • 8 = 160,160)

The amount Kate spent $ 56 of the $ 140 she had.

To find out how much Kate spent, we need to calculate 2 / 5 of the total amount she had, which was $ 140.By multiplying fractions we mean the product of a fraction with another number or a fraction. The product of such multiplication could be a fraction or a whole.

To do this, we can multiply $ 140 by the fraction 2 / 5:

= $ 140 * 2 / 5

= $280 / 5

= $ 56

Therefore, Kate spent $ 56 of the $ 140 she had.

Answer:

The unknown is 44

Step-by-step explanation:

We need to solve for x in the proportion given by :

11 / 1 = x / 4

multiply both sides by 4 to isolate x

11 * 4 / 1 = x

x = 44

Answer:

(B) The volume of a rectangular pyramid is 1/3 the volume of a rectangular prism. The volume of the rectangular pyramid is 66 cm3.

Step-by-step explanation:

Volume of a rectangular prism:

The volume of a rectangular prism is given by:

[tex]V_R = A_{b}*h[/tex]

In which [tex]A_b[/tex] is the base area and h is the height.

Volume of a pyramid:

[tex]V_P = \frac{A_{b}*h}{3}[/tex]

Relation:

From this, given the same base and the same height, the volume of the pyramid will be a third of the rectangular prism.

A rectangular prism has a volume of 198 cm³

So the volume of the pyramid is 1/3 of this, that is, 198/3 = 66 cubic centimers.

The correct answer is given by option B.
