Answer:

[tex]5\[/tex]

Step-by-step explanation:

Let x be cost of 1 eraser.

[tex]5 +4x=25[/tex]

[tex]4x=20[/tex]

[tex]x=5[/tex]

Answer:

The buyer bought four erasers and a magazine for $25.

The cost of each magazine is $5

The cost of an eraser is x dollars

The cost of 4 erasers is 4x

Step-by-step explanation:

Cost of the Erasers + Cost of the Magazine = Total Cost

4x + $5 = $25

Subtract 5 from both sides to isolate the term with the variable.

4x + 5 -5 = 25 -5

4x = 20

The last thing you do is you divide it by 4 on both sides to isolate the variable.

x = 20/4 = $5

Answer:

[tex]x = 42[/tex]

Step-by-step explanation:

Given

The diagram above

Required

Find x

When two parallel lines are divided in such a way as it is in the above figure;

x and 138 are said to be supplementary angles

The rule about supplementary angles is that, they add up to 180

In other words,

[tex]x + 138 = 180[/tex]

To solve this, we subtract 138 from both sides

[tex]x + 138 - 138= 180 - 138[/tex]

[tex]x = 180 - 138[/tex]

[tex]x = 42[/tex]

Hence, the value of x when solved using the properties of parallel lines is: [tex]x = 42[/tex]

Answer:

28.13 cm

Step-by-step explanation:

The first step we need to do is create the segment AC.

Then, we can find its length using the law of cosines in the triangle ABC:

b^2 = a^2 + c^2 - 2*a*c*cos(B)

b^2 = 8^2 + 6^2 - 2*8*6*cos(95)

b^2 = 64 + 36 - 96*(-0.0872)

b^2 = 108.37

b = 10.41 cm

Then, in the triangle ADC, we can use the Pythagoras' theorem to find the length of DC:

DC^2 + DA^2 = AC^2

DC^2 + 25 = 108.37

DC^2 = 83.37

DC = 9.13 cm

So the perimeter of ABCD is:

Perimeter = AB + BC + CD + DA

Perimeter = 6 + 8 + 9.13 + 5 = 28.13 cm

Answer:

The perimeter of the shape is 28.13 cm

Step-by-step explanation:

First of all, we will have to draw a line from point A to point C. This will divide the shape into two parts, both of which are triangles.

We will use the dimensions of the newly formed triangle ABC to get the side AC.

The cosine formula will be apt for this purpose:

[tex]AC^{2}=AB^{2}+BC^{2}-(2 \times AB\times BC\times cos \theta)[/tex]

[tex]AC^{2}=6^{2}+8^{2}-(2 \times 6\times 8\times cos( 95))=108.37[/tex]

[tex]AC=\sqrt{108.37}=10.41 cm[/tex]

Now we have AC as 10.41 cm,

we can see that AC forms the hypothenuse of the right-angled triangle ADC.

From Pythagoras' theorem,  DC can be calculated as

[tex]DC =\sqrt{AC^{2}- AD^{2}}[/tex]

[tex]DC =\sqrt{10.41^{2}- 5^{2}}= 9.13 cm[/tex]

Therefore the perimeter of the shape is 8 + 5 + 9.13 + 6 =28.13 cm

The perimeter of the shape is 28.13 cm

Step-by-step explanation:

If the volume of the box is 9. The possible side lenths are:

V = L x W x H

9 = 3 x 3 x 3.

What I did was estimated how 9 could be split up into 3 so that it’ll make sense for L x W x H.

Answer:

The rate of change represents the number of stamps that is added each month.

The rate of change is 3

The initial value represents the number of stamps she had before she started adding 3 every month.

The initial value is 8

Step-by-step explanation:

The rate of change is 3 because that is how many stamps are added each month.

The initial value is 8 since that was the original amount she had before adding stamps every month.

Answer:

Answers are below

Step-by-step explanation:

The rate of change represents the number of stamps added every month.

The rate of change is 3.

The initial value represents how stamps she had before adding more.

The initial value us 8.

Answer:

V = 5(12)(7) which is F.

Step-by-step explanation:

V = LWH

L = 12

W = 5

H = 7

12 * 5 * 7

Answer:

if you need to find the area, the answer is 420, I think All in all the answer is F <last one>

Step-by-step explanation:

I think the first thing you do is L x W (12 x 5), which is 60. Then you do 60 x H (60 x 7), and you will get 420.

I am not entirely sure if I got it right.

Answer: D

Step-by-step explanation:

Answer:

a + b = 1 or 4

Step-by-step explanation:

The integer = 3a5b

The factors of the integer includes 5 and 6

∴ 5 × 6 = 30 is a factor of the integer hence 10 is also a factor which gives b = 0

We check for factors of four digit numbers with the first digit = 3, last digit = 0, penultimate to the last digit = 5 and divisible by 30

We have a50 divisible by 30, which gives, a5 divisible by 3 which includes

15 and 45 hence a can be 1 or 4 and a + b = 1 + 0 = 1 or  4 + 0 = 4.

Answer:

Step-by-step explanation:

Required:How much more rain fell in Dubaku's town than in Elliot's town?

8 centimeters of rain fell in Dubaku's hometown

2.36 centimeters of rain fell in Elliot's hometown

We are asked to find how much more rain fell in Dubaku's town than in Elliot's town so it is calculated as the difference between the rain in both of there towns and is given by:

Answer:

3.26

Step-by-step explanation:

Rounding to the nearest hundredth means round to the nearest two decimal places.

To do this, all we need to look at is the 3rd decimal place.

Since 4 is not 5 or greater, that means we must round down, no matter how close it is to 5.

Therefore, the answer should just be 3.26

Answer:

3.26

Step-by-step explanation:

You round the second place after the decimal (6) by the place after it (4).

If the place after the number you need to round is a 5 or up, the decimal you round goes up one, if it is a 4 or lower it stays the same.

E.G. if 3.2649 was 3.2659 the hundreds would be rounded to 3.27. Since it's a 4, the six stays the same at 3.26.]
