Please help me 4⅗ ÷ ⅕ =

Answers

Answer:

23

Step-by-step explanation:

just used a calculator

23

Let’s start by making the mixed number an improper fraction. To do this you multiply the whole number by the denominator and add the numerator.

4 x 5 + 3 = 23

No we have 23/5 divided by 1/5

We have common denominators but you don’t need them for multiplying and dividing fractions. To discuss fractions you just go across, but there’s a thing. You have to flip the second fraction then you can multiply instead of divide.

So

23/5 x 5/1

23 x 5 = 115

5 x 1 = 5

115/5

This can be simplified to 23 because 5 divided by 115 is 23.

Answers

Answer:

[tex]x=\frac{n}{p}m[/tex]

Step-by-step explanation:

Since we have two variables on the left side (x and p), and they are being divided, we need to do the opposite in order to get it to the other side. Therefore, we multiply both sides of the equation by m.

Doing that, we get

[tex]\frac{x}{m} m=\frac{n}{p}m\\\\\\So,x= \frac{n}{p}m\\[/tex]

The probability that record drawn randomly from a standard deck of 52 cards is a four

Answers

Answer:

1/13

Step-by-step explanation:

no.of sample space n(S) = 52

no.of favourable cases n(E) = 4

probability of getting a four p(E) = n(E) / n(s)

or, 4/52

or 2/26

or 1/13

therefore,the probability of getting a four is 1/13.

Find the surface area and the volume of the prism .​

Answers

Answer:

[tex]14 + 4 + 5.5 + 3 + 5.5 {?}^{2} [/tex]

Answer:

Step-by-step explanation:

We have 2 congruent large prisms and one small one.

Volume of a large one= 2*2*14 = 56 cm^3.

Volume of smaller one = 4*3*2 = 24 cm^3.

So volume of the whole prism

= 2*56 + 24

= 136 cm^3.

Surface area of a large one = 3*2*14 + 2*2*5.5 + 2*2*2 = 114

Surface Area  of smaller one = 4*3*2 + 2*2*4 =  40

So surface area of the whole prism

= 2 * 114 + 40

= 268 cm^2.

NEED HELPS ASAP PLS AND THANK U

Answers

Answer:

D)  

Step-by-step explanation:

y = 12x.

A) x=8, so that y = 12(8) = 96.  It's on the line

B) x = 10, so that y = 12(10) = 120.  It's on the line

C) x = 15, so that y = 15(12) = 180.  It's on the line

D) x = 18, so that y = 18(12) = 216, not equal to 206.  So, the point is not on the line.

The perimeter of a regular pentagon is 4 1/7

cm. Find the length of its each side​

Answers

Answer:

29/35 cm for each of the 5 sides

Step-by-step explanation:

The perimeter is the length of all the sides added together.  A pentagon has 5 sides.  So you'd need to divide 4 1/7 by 5.

It might be easier to divide 4 by 5 and then divide 1/7 by 5 then add the two numbers together.

4/5 = 0.80 or 8/10

1/7 divided by 5  is written as (1/7) / (5/1)

When you divide a fraction by a fraction, you flip the fraction in the denominator over and multiply the new fractions.

So (1/7) / (5/1)  turns into   1/7  x  1/5 = 1 / 35

Adding 8/10 + 1/35, you first need to find the common denominator which would be 70.

8/10 would turn into 56/70

1/35 would turn into 2/70

Add them together now and you get 58 / 70.  This can be reduced down to

29 / 35.

Before doing the question let's recall that their are two types of shapes mostly , irregular and regular . Regular shapes have all their sides equal while irregular doesn't have. And here The given shape is pentagon so it will have 5 sides . Also , it's perimeter is given i.e sum of it's all sides , If we assume it's one side to be s then perimeter will be (s+s+s+s+s) more conveniently 5s . Now , heading to our question ,

[tex]{:\implies \quad \sf 5s=4\dfrac{1}{7}}[/tex]

[tex]{:\implies \quad \sf 5s=\dfrac{4\times 7+1}{7}}[/tex]

[tex]{:\implies \quad \sf 5s=\dfrac{28+1}{7}}[/tex]

[tex]{:\implies \quad \sf 5s=\dfrac{29}{7}}[/tex]

[tex]{:\implies \quad \sf s=\dfrac{29}{7\times 5}}[/tex]
