What is the product of -8 1/3 and 3 2/5

Mathematics
1 answer:

-28 1/3

To get this, first, transform the mixed numbers into improper fractions. To do this, multiply the denominator and the whole number then add to the numerator.

Once this is done, set up the equation of -25/3 x 17/5 and cross multiply - -25 and 17 then 3 and 5. Don't forget that the 25 is negative so the product of the numerators will be negative!

Once this is done, you'll have a larger negative improper fraction. You'll need to transform it into a mixed number. To do this, find how many times 15 goes into 425 (28). The remainder will be the fraction or 1/3. Make sure to simplify the fraction!

Hope this helps!

Find the volume of a pyramid with a square base, where the side length of the base is 15.9\text{ cm}15.9 cm and the height of th
jeka94

Answer: 1,162.9 cm3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a square pyramid: 1/3 x base area x height

Where

base area = base side length ^2

Replacing with the value given:

Base area = 15.9^2

base area : 252.81 cm2

Back with the volume formula:

V = 1/3 x base area x height

Replacing with the values given and solving for V (volume)

V = 1/3 x 252.81 x 13.8 = 1,162.9 cubic centimeters

Feel free to ask for more if needed or if you did not understand something.

Jenny works in a picture framing shop. She has a function f(x) equals X +2 that find the size of a square frame, given a picture
Iteru [2.4K]

Given:

The function for size of a square frame is

f(x)=x+2

where, x is the side length of the picture.

The function for the price in dollars for the frame is

p(x)=3x

To find:

The single function for the price of a picture with an edge length of x.

Solution:

We know that, for a picture with an edge length of x.

Size of a square frame = f(x)

Price in dollars for the frame = p(x)

Single function for the price of a picture with an edge length of x is

(p\circ f)(x)=p(f(x))

(p\circ f)(x)=p(x+2)       [\because f(x)=x+2]

(p\circ f)(x)=3(x+2)           [\because p(x)=3x]

Let the name of this function is c(x). So,

c(x)=3(x+2)

Therefore, the required function is c(x)=3(x+2).

In the following figure, the value of x is____
zubka84 [21]

Answer:

x ≈ 8.3 ( to the nearest tenth )

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos41° = \frac{adjacent}{hypotenuse} = \frac{BC}{AB} = \frac{x}{11}

Multiply both sides by 11

11 × cos41° = x, thus

x ≈ 8.3
