Answer:

14 yards of string.

Step-by-step explanation:

Since each kite needs 4 2/3 yards of string and there are 3 kites, we have to multiply 4 2/3 by 3.

So, 4 2/3 × 3 = 14.

Answer:

The slope is 1/4 so the slope intercept form is y=1/4+3

Step-by-step explanation:

To find the slope the easiest way from looking at a graph is just to find the rise over run. From looking at the graph we can see that the next point from 0,3 is 4,4. The y here is increased by 1, which means the rise is 1. The x is increased by 4 so the run is 4. From putting rise (1) over run (4) the slope is 1/4. The formula for slope intercept is y=mx+b. m is slope so we substitue that for 1/4 so now we have y=1/4x+b. Then the b is the y intercept, or, at what point the line crosses the y line. Which in this case is 0,3 so the y intercept would be 3 because that is what height it crosses the y line.

Answer:

5.38 units

Step-by-step explanation:

Because of the base angle theorem converse, This triangle is an isosceles triangle.

Because this is an isosceles triangle, because the leg of the triangle is 5.38 units, that means the other leg has to be 5.38 units

You may be asking, how do I know it's the other leg that's congruent.

Well, the angle opposite to the 90° angle is the hypotenuse, and we want the line segment opposite of the 45° angle. And both the legs are opposite to the 45° angles.

Answer:

x > - 8

Step-by-step explanation:

Given

48 > - 6x

Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.

- 8 < x , thus

x > - 8

Answer:

x >-8

48>−6x

Step 1: Flip the equation.

−6x<48

Step 2: Divide both sides by -6.

[tex]\frac{-6x}{-6}[/tex]< [tex]\frac{48}{-6}[/tex]

x>−8

Answer:

4

Step-by-step explanation:

You need to try out all the numbers.

lets start with 4

if there where 4 red marbles then there would be 9 times as many marbles

so 4 x 9 = 36

Now we add and see if the sum is 40

36 + 4 = 40

We got it on the first try

You can use the same method on more problems like these.

Answer:

C

Step-by-step explanation:

Answer:

The y-intercept is (26, 0)

Step-by-step explanation:

The Y intercept is the point at which the line crosses the  y-axis, or when x is equal to zero. Here when x = 0, y = 26. So the y-intercept is (26, 0). They want to trick you into choosing the slope is -1/6, but that is wrong because id you look at the x-axis it is not going by 1's.

Answer:

24ft²

Step-by-step explanation:

divide up the shape:

big triangle:

(looking for base)

9.8²= 4² + b²

b  = 8.95ft

(finding area)

0.5*8.95*4 = 17.9ft²

small triangle:

(looking for base)

12-8.95=3.05ft

(finding area)

0.5*3.05*4 = 6.1ft²

Whole Shape:

17.9+6.1 = 24ft²

Answer:

72.225 $

Step-by-step explanation:

The price per pack: 5.00 $

When the amount of packs is > 10 :

90 % * 5 $ = 4.50 $ before tax.

The price of 15 packs:

4.50 $ * 15 = 45 + 22.5 = 67.5 $ before tax.

After tax:

107 % * 67.5 $  = 72.225 $ after tax.

The rent in the 5th year is $2120.

The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations. We can find the amount regularly increasing by using arithmetic.

As per the given data:

Cost of the apartment per month during the first year is given, also the increase in rent every year is given.

We have to find out the monthly rent during the 5th year of living in the apartment.

For finding out the monthly rent during the 5th year of living in the apartment:

Rent in first year + Increase in rent in each year × (5 - 1)

= 1400 + 180 × 4

= 1400 + 720

= $2120

The rent in the 5th year is $2120.

Hence, The rent in the 5th year is $2120.

Answer:

a= 12

b=-2

Step-by-step explanation:

12 x -2 = -24

12 - (-2) = 14

12 + (-2) = 10

The two integers are 12 and -2.

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Let x and y be the two integers.

So it is given that,

Product of two integers =  – 24

⇒ xy = - 24   ....(i)

The difference between the two integers =  14

⇒ x - y = 14  ...(ii)

The sum of the two integers = 10

⇒ x + y = 10     ....(iii)

Now adding equation (ii) and (iii) we get,

2x = 24

⇒ x = 12

Putting the value of x in equation (i) we get,

12y = - 24

⇒ y = - 2

So the required integers are 12 and - 2.
