Tammy brought 3 apps for $2.40. At the same price, how much would 10 apps cost​

Mathematics
1 answer:
vitfil [10]3 years ago
3 0

Answer:

The answer is $8.00.

Step-by-step explanation:

First, you have to find how much for each app so you have to divide by 3 :

3 apps = $2.40

1 app = $2.40 ÷ 3

1 app = $0.80

Next, you have to multiply it by 10 :

1 app = $0.80

10 apps = $0.80 × 10

10 apps = $8.00

What is this aneswer to this question 8(x-4)10x
FrozenT [24]
I can't tell you the answer but I can tell you what to do. First you have to take what is in parentheses first. x-4... But I think you made this up because your not supposed to put 10× but the 8(x-4) that makes sense but the last part doesn't..

Solve for r.<br> P=q+r+s
ddd [48]

In linear equation, The value of the r is a P-q-s.

According to the statement

We have to find that the value of the r .

So, For this purpose, we know that the

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.

From the given information:

The equation is a :

P=q+r+s

This a type of the linear equation then

P=q+r+s

Now, rearrange the terms

P-q-s = r

Then the value of the r is

r = P-q-s .

So, In linear equation, The value of the r is a P-q-s.

You randomly survey students about whether they like hamburgers or hot dogs. of 129 students who like hamburgers, 46 like hot do
Ludmilka [50]

 Here is the two-way table and the marginal frequencies in bracket:                          

                                 Like hamburger    do not like hamburger      Total

Like hot dog                    46(0.16)             54 (0.10)                        100(0.36)

Do not like hot dog          83(0.30)           95 (0.34)                        178(0.64)

Total                                 129 (0.46)             149 (0.54)                  278(1)

<h3>What is the two-way table?</h3>

Number of people who like hamburger but do not like hot dog = 129 - 46 = 83

Number of people who do not like hamburger and do not like hot dog = 149 - 54 = 95

Total number of people who like hot dog = 46 + 54 = 100

Total number of people who do not like hot dog = 83 + 95 = 178

Total = 100 + 178 = 278

The marginal frequency can be determined by dividing each number by the total number of people in the survey.

  • marginal frequency of people who like hot dog = 100 / 278 = 0.36
  • marginal frequency of people who do not like hot dog = 178 / 278  = 0.64
