Answer:

5/12(poetry) + 2/5(biographies) = 25/60 + 24/60 = 49/60

60/60 - 49/60= 11/60

11/60 are the remainder of the books in the shipment.

Step-by-step explanation:

(x − 25) = 7

    +25  +25

        x = 32

5x + 15 = 28

     -15     -15

    5x =  13

     /5     /5

x= 13/5

(4x + 15)=24

Answer:

Apply the distributive property to the left-hand side of the inequality.

Step-by-step explanation:

Using PEMDAS, what you need to do first is clear!

P -> parentheses ( distribute, clear them out, etc. )

E -> exponents

M -> multiplication

D -> division

A -> addition

S -> subtraction

Going in order, you would apply the distributive property first to clear out the parentheses.

Formula used,

Area of rhombus = Base × height

Substituting the values,

\( \longrightarrow\)Area = 18 × 15.5

\( \longrightarrow\) Area = 279 cm²

Therefore, 279 cm² is the area of the rhombus .

Answer:

D) 279 cm²

Step-by-step explanation:

Area of a rhombus formula:
\(A=bh\)

This formula is also used for squares and rectangles.

So, we can substitute in our values such as:

A=(18)(15.5)

simplify

A=279

Now, add our label and units:

A=279 cm²

Answer

the area of the entire rocket is  44

area of the triangle=6

area of the rectangle=30

area of the trapezoid=8

Step-by-step explanation:

triangle= bxh/2 so 4x3= 12/2= 6

rectangle= bxh so 3x10=30

trapizoid= A=a+b2h so 3+5= 8/2= 4x2= 8

6+30+8=44

Answer:

96in³

Step-by-step explanation:

Area of trapezium = ½ X (sum of parallel sides) X distance between them

= 1/2 (4 + 12) X 6

= 1/2 X 16 X 6

= 48.

volume = 2 X 48

= 96in³

Answer:

60 in

Step-by-step explanation:

15 x 4= 60

Answer:

Hello,

Area -

You have to times the height and the width

Width is top and Height is the side

Take 15 x 6 = 90 cm

Perimeter -

(This parts a little hard for me)

Then I think you have to do...

The perimeter of a parallelogram is the distance around the outside of the parallelogram

A parallelogram has four sides with opposite sides being congruent.

The formula for finding the perimeter is Side A + Side B + Side A + Side B.

(But here's a tip the side are the same because they are the same height)

Answer:

The answer is correct

Step-by-step explanation:
Disclaimer: x will represent b

The reason that it is correct is because it says that "each also buys a healthy snack bag". If we look at the problem, we know that each friend needed a ticket to get in, which cost 6.75. Let's say that the price of the Healthy Snack Bag is x. We know that four friends go together, and each has to pay a ticket. So we have

4 Friends each get a healthy snack bag with the price of x and a ticket that costs 6.75.

So the price that each friend had to pay was 6.75(ticket) + x(snack)
All four friends needed to do that, so we have 4 of the top equation. That can simplify to 4(6.75+x). It also says that the total cost of all 4 of them was 37. So 4(6.75+x) = 37. By using the distributive property, you get 27+4x=37.
With some simple algebra, and by isolating x, you get x = 2.5.

Answer:

\(≈134 \: {cm}^{2} \)

Step-by-step explanation:

Given:

r (radius) = 2,4 m

h (height) = 6,5 m

π = 3.14

Find: A (surface area) - ?

\(a(surface) = 2\pi {r}^{2} + 2\pi \times r \times h\)

\(a(surface) = 2 \times 3.14 \times ({2.4})^{2} + 2 \times 3.14 \times 2.4 \times 6.5 ≈134 \: {cm}^{2} \)

Answer: 134 square meters

Step-by-step explanation:

Answer is 25 degrees.

Answer:

k=12

Step-by-step explanation:

Top left angle is 84 degrees also, due to alternate interior angles cut by the transveral.

2 sides are congruent, leaving bottom left corner angle also 84 degrees.

Write an equation to solve for k:

84+84+k=180

simplify

168+k=180

subtract 168 from both sides

k=12

Answer:

33.3%

Step-by-step explanation:

There are 3 sections the spinner can land on, and only one meets the requirement (less than 3, so the 2 section is the only one). Therefore the chance of landing on 2 is 1/3, or 0.333...... which can be converted into percentage by multiplying it by a hundred.

-0.333..... x 100 = 33.33333....

Answer: .28, .16, 0, .34

Step-by-step explanation:

The length of segment NB is 0.833

From the question, we have the following parameters that can be used in our computation:

The rectangle

The area of the rectangle is

Area = (20 + x) * 10

The area of MNBC is

Area  = 1/2 * 10 * (x + 20 + x - 5)

Area  = 5(2x + 15 )

The area of the quadrilateral MNBC is 40% of the total area of the rectangle

So, we have

5(2x + 15) = 40% * (20 + x) * 10

5(2x + 15) = 4* (20 + x)

When evaluated, we have

x = 0.833

Answer:

X=1

Step-by-step explanation:

The total area of the rectangle is 20x10=200

so the area of MNBC is: 40%x200=80

MC= 20-5=15

so (x+15).10/2=80 (according to the trapezoidal area formula)

x=1

so the answer is 1

2.1 | 1 Cabin | How: Divide 10.5 by 5 and you get 2.1
14.7 | 7 Cabins | How: Multiply 2.1 and 7 and you get 14.7

I Hope This Helped :D

Answer:

2.1 and 14.7

Step-by-step explanation:

If 10.5 hectares are used for 5 cabins then how many are used for 1?

To put it simply,

10.5 hectares = 5 cabins

x = 1 cabin

You can cross multiply to obtain the answer:

10.5 = 5x

x = 2.1 hectares

Similarly, the same method can be applied in order to achieve the other unknown value:

10.5 hectares = 5 cabins

x = 7 cabins

After cross multiplying,

73.5 = 5x

x = 14.7 hectares
