Answer:

Number of week they have same amount = 4 week

Step-by-step explanation:

Given:

Amount Joe have = $14

Joe's saving per week = $10

Amount Josh have = $26

Josh saving per week = $7

Find:

Number of week they have same amount

Assume;

Number of week they have same amount = a

So,

(14 + 10a) = (26 + 7a)

3a = 12

a = 4

So,

Number of week they have same amount = 4 week

Answer:

B

Step-by-step explanation:

Remark

I'm not sure why (f + g)x is there at all. All you are instructed to do is add the two given functions together.

Solution

(f+g)y = 5x^2 - 2y + 1 - 3y^2 - y - 2

(f+g)y = 2y^2 - 3y - 1

That's B

sorry if it is wrong

Answer:

4

Step-by-step explanation:

30*4=120 because 12=3*4 and 30*4 is basically 3*4*10, and since it's asking for the scale factor, we test to see if 12*4=48, which it does.

Answer:

First box, fourth box, sixth box

Step-by-step explanation:

Positive in division means either both numbers are positive or negative

The two dot plots are missing, so i have attached it.

Answer:

The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles

Step-by-step explanation:

From the attached image, we are told to compare the means for each plot to the nearest tenth.

Mean = Σx/n

Now, from the image, total number of miles run by the 14 students at the beginning of the school year is;

(1 × 7) + (2 × 8) + (4 × 9) + (4 × 10) + (2 × 11) + (1 × 12) = 133

Mean of miles run at the beginning of the school year = 133/14 = 9.5 miles

Again, from the table, total miles run at the end of the school year = (2 × 8) + (2 × 9) + (4 × 10) + (3 × 11) + (3 × 12) = 143

Mean of miles run at the end of the school year = 143/14 = 10.2 miles

Thus;

The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles

You just literally mark the graph, you see the 1st points (2,12) go on the X axis to 2, then go up to 12 and mark that as a point. and continue with this tactic with the rest.

Answer:

I think this is correct. <3

Answer:

A

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

1. P(E)>P(D) (Event E is more likely to occur, therefore it has a greater probability)

2. P(E)>0.5 (The probability of event D is given as 0.5, so rewrite P(D) in the inequality)

3. 0.5 is equal to 0.5 and 0.1 is less than 0.5, so you can rule out options A and D

4. This leaves us with options 1.5 and 0.9, but it is impossible to have a probability that is greater than equal to one, so you can immediately rule out B

5. After this elimination process, the only remaining answer is C) P(E)=0.9

Answer:

largest ∡ = 81°

Step-by-step explanation:

44 + 3x - 11 + 4x - 7 = 180

7x + 26 = 180

7x = 154

x = 22

4(22)-7 = 81

Answer:

y = 9°

Step-by-step explanation:

Vertical Angles law

63° = 11y - 36

63+36 = 99

11y = 99

y = 9

Answer:

√{99×33×3}=√{33×3×33×3}=√(33²×3²)=±33×3=±99

Answer:

99

Step-by-step explanation:

Cause 33×3=99 ,and the function of the root is to get the number that we multiply it ti itself

For example [tex]\sqrt{4}[/tex] =2 cause 2×2=4 ,so[tex]\sqrt{2*2}[/tex] =[tex]\sqrt{4}[/tex] which is =2

so [tex]\sqrt{99^{2} }[/tex] =99

Answer:

Step-by-step explanation:

Let the number be 'x'

Half a number = [tex]\frac{1}{2}x[/tex]

Half a number increased by the quotient of p and t

[tex]\frac{1}{2}x+\frac{p}{t}[/tex]

Answer:

y = 1/2x + 1

Step-by-step explanation:

The slope is the change in y over the change in x. The line goes down one and two left, making the slope 1/2.

The line crosses the y axis at positive  1 and that is the y-intercept.

Answer:

1.  42/x

2.  14 students

Step-by-step explanation:

1.  42 divided by x

    x=students on trip last year

2. 42 divided by 3

    42/3=14 students this year

[tex] \implies \sf \boxed{ \sf7.71}[/tex]

The remainder is 5 when 54 is divided by 7.

Division in mathematics is the process of dividing an amount into equal parts. For instance, we may split a group of 20 people into four groups of 5, five groups of 4, and so on.

Given:

We have to divide 54 by 7.

So, the division is

                            7 | 54 | 7

                                  49

                              -_____

                                     5

Then, the remainder is 5 because we do not have number further and 5 is smaller than divisor.
