Answer:

√88

Step-by-step explanation:

a^2 + 9^2=13^2

a² = 13² - 9²

a² = 169 - 81

a² = 88

Take square root of both sides

a = √88

Answer:

4

Step-by-step explanation:

31 - 6 = 25

25/4 = 5

because its LESS than that, it has to be lower than 5, therefore its 4.

Kim should be 12 years old.

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, Josh is 6 years older than 4 times Kim's age and the sum of their ages is less than 31.

From the information, let's consider Josh's age be J and that age Kim's be K

As given,

J = 6 + K ..............(i)

And,

J+K < 31

Substituting in eq(i)

6+K+K < 31

2K < 25

K < 25/2

K < 12.5

Since, Kim's age should be less than 12.5

Hence, Kim's age is 12 years.

Answer:

13.884 grams

Step-by-step explanation:

From the question:

1 carat = 0.2 grams

The highest priced diamond = 69.42 carats.

Hence:

1 carat = 0.2 grams

69.42 carats = x grams

x grams = 69.42 × 0.2 grams

x grams = 13.884 grams

Hence, the weight of the highest priced diamonds is 13.884 grams.

Answer:

-12

Step-by-step explanation:

Ok so I'm guessing that's a -4 but if its not, please correct me.

y= -5 is going to be plugged into 2y+2-4

This means that 2(-5)+2-4=?

2(-5) is the equivalent to 2 times -5, which is -10 (you solve multiplication first because order of operations)

Now, 2-4=-2

So using this, let's combine both equations!

-10+-2=?

?=-12

It's a lot of steps but they get easier the more you do them <3

The number of boys attended are 49.

For the given question.

Let the number of girls be 'x' = 63.

Let the number of boys be 'y'.

The ratio of girls to boy is 9:7.

Thus,

x/y = 9/7

Boys  = ?

y = 7x/9

Put x = 63

y = 7×63/9

y = 49

Answer:

h(n)=0−9(n−1)

Step-by-step explanation:

From the recursive formula, we can tell that the first term of the sequence is 0

and the common difference is -9

This is the explicit formula of the sequence:

h(n)=0−9(n−1)

Note that this solution strategy results in this formula, however, an equally correct solution can be written in other equivalent forms as well.

Step-by-step explanation:

If you add the numbers above, they equal the number 18,090 which makes them equivalent.

Step-by-step explanation:

the difference of 2x and 15 is less than or equal to the

sum of 4x and 17

i.e.,

2x - 15 < 4x + 17

if you want to find ahead then

2x - 15 = 4x + 17

2x - 4x = 17 + 15

- 2x = 32

x = - 32/2

x = - 2

Answer:

55 degrees :)

Step-by-step explanation:

all triangles add up to 180 degrees.

we already have 70 degrees and since <S = <R they are the same # of degrees.

subtract 70 from 180 and we get 110.

divide 110 by 2=55

<S 55

Answer:

4,923.75ft²

Step-by-step explanation:

The area of the backyard = Length * width \

Area of the backyard = 75 3/4 * 81 1/4

Area of the backyard = 303/4 * 325/4

Area of the backyard = 6,154.6875ft²

If 3/4 of the fence is finished, the area of the finished part is expressed as;

Finished part = 1/5 * 6,154.6875

Finished part = 1,230.9375ft²

Part left unfinished = 6,154.6875-1,230.9375

Part left unfinished  = 4,923.75ft²

y = 13/8

Step-by-step explanation:

Here are the steps I did:

1. y - 7/8 = 3/4 x 2/2

2. y - 7/8 + 7/8 = 6/8 + 7/8

3. y = 13/8

Answer:

Y in (-oo:+oo) Y- (7/8) = 3/4 // - 3/4. Y- (7/8)- (3/4) = 0. Y-7/8-3/4 = 0. Y-13/8 = 0 // + 13/8. Y = 13/8. Y = 13/8.

Answer:

You will graph a function with the equation being y = 4x - 3, to plot this function read step by step explanation.

Step-by-step explanation:

First we have to find the equation of the line so we do....

24x - 6y = 18

24x = 18 + 6y

6y = 24x - 18

y = 4x - 3

Now that we know the equation we just have to find two point by using this equation and connect them between each other in order to graph the function represented by this equation. For example

For x = 0

y = 4x - 3

y = -3

So we know that there is a point (0, - 3)

For x = 1

y = 4x - 3

y = 4 - 3

y = 1

So we know that there is a a point  (1, 1)

Connect the two point and you will get the function graph
