Question

Anita Read 24 Pages Of Her Book In 12 Minutes . How Long Will It Take Her To Read 34 Pages ?

Solution 1

17 minutes In order to solve this you make a porportion: 24/12=34/x You do (34×12)÷24 34×12=408 408÷24= 17 ~JZ Hope IT helps you

Question

A circular pizza has a diameter 10cm.what is the approximate area of the pizza?(use pi=3)

Solution 1

You would multiply 10 times \pi (3.14) and get 31.40 cm squared

Solution 2

Radius= 1/2 diameter= 1/2(10)= 10/2= 5

Circle Formula for Area= πr^2

C= πr^2

= (3)(5)^2

square 5; when squaring, multiply the number by itself one time

= 3(5*5)

= 3(25)

= 75 cm^2

ANSWER: The approximate area is 75cm^2 (using 3 for π).

Hope this helps! :)

Question

Yesterday's low temperature was − 2 . 5 ∘ C −2.5 ∘ Cminus, 2, point, 5, degree, C. Today's low temperature is 5 55 times as low as yesterday's low temperature.

Solution 1

The temperature today would be -12.5 degrees.

If today's temperature is 5 times as low as yesterday's temperature, you just have to multiply it by 5.

-2.5 x 5 = -12.5

If today's temperature is 5 times as low as yesterday's temperature, you just have to multiply it by 5.

-2.5 x 5 = -12.5

Question

The set of all numbers on the number line are called the ____________. A number that has an equivalent terminating or repeating decimal is called a(n) _______________.
A number that has an equivalent decimal that is non-repeating is called a(n) _______________.
Any number that can be written as a fraction of integers is a(n) ______________.

Solution 1

The set of all **numbers **on a number line is called the "**Real Numbers**".

Any **number **that can be represented as the **ratio **of two **integers **and where the **denominator **is not zero is referred to as **rational**.

The **set **of all **numbers** on a **number **line is called the "**Real Numbers**".

A **number **that has an **equivalent terminating **or repeating **decimal **is called a "**Rational Number**".

A **number **that has an **equivalent** **decimal** that is non-repeating is called an "**Irrational Number**".

Any **number **that can be **written **as a **fraction **of **integers **is a "**Rational Number**".

Hence, the **set **of all **numbers** on a **number **line is called the "**Real Numbers**".

Question

The drawing is composed of a rectangle and a semicircle 18 cm 22 cm

Solution 1

What do you need?

The perimeter is L + w + L + perimeter of a semicircle.

L = 22 cm

W = 18 cm

Perimeter can be one of two answers. You need to specify where the semicircle is. Formula for semicircle is

pi * r

r = 18/2 = 9 or

r = 22/2 = 11

So the perimeter of the semi circle is pi * 9 = 25.12 The total Perimeter = 22 + 22 + 18 + 25.12 = 87.12

It can also be 22 + 18 + 22 + 34.54 = 96.54 There are even more possiblities for perimeter. I would have the same problem if you asked about area.

Why not put more details in and I'l give you the correct answer. Here is what we need to know

1. Where is the circle on the 22 cm side or the 18 cm side?

2. What are you looking for: perimeter or area? As soon as you answer these I'll be back.

Question

What are the variables and coefficients on the problem 5.4 times 2 + 2.8 times 2

Solution 1

So remember that variables are variable or in other words they can change like x

coeficients are things that yo uknow like 2,5,3/5

so since all of them are numbers, all of them are coeficients

coeficients are things that yo uknow like 2,5,3/5

so since all of them are numbers, all of them are coeficients

Question

What is the height of a building in meters if it takes a rock 3.8 seconds to drop from its roof

Solution 1

height = 70.756 m

x = ut + 0.5at²

where:

x is the distance that we want to calculate

u is the initial velocity of the body = 0 (assuming the body starts from rest)

a is the acceleration due to gravity = 9.8 m/sec²

t is the time taken = 3.8 seconds

x = ut + 0.5at²

x = 0(3.8) + 0.5(9.8)(3.8)²

x = 70.756 m

Hope this helps :)

Question

arnold calculated his mean score after three rounds of golf.he noticed that his score in the first round was 3 strokes below the mean and his score in the second round was 1 stroke below the mean if Arnold’s mean score was 72 what was his score in the third round

Solution 1

Mean = 72

First round = 72-3 = 69

Second round = 72-1 = 71

Third round = 76

Explanation:

Total score = 72*3 = 216

69+71+x = 216

140+x = 216

x = 76

First round = 72-3 = 69

Second round = 72-1 = 71

Third round = 76

Explanation:

Total score = 72*3 = 216

69+71+x = 216

140+x = 216

x = 76
