Answer:

Approx : 14.0294372515

Step-by-step explanation:

There are 2 congruent right triangles in this trapezoid. The hypotenuse and adjacent side lengths are 19 and 17 respectively. Using the Pythagorean Theorem, 19^2-17^2 is 72. The square root of 72 is approximately 8.48528137424. That is the length of the portions on the bottom that don't include the length x. 8.48528137424*2 is approximately 16.9705627485. 31-16.9705627485 gives you the length of the side x.

What is the perimeter of JKL?

Answers

Answer:

The perimeter of JKL is 60 units.

Step-by-step explanation:

The two tangents of a circle formed by a vertex outside the circle will always be the same distance, this means that JA = JB = 13, LA = LC = 7, and KB = KC = 10. JL = JA + LA = 20, KL = LC + KC = 17, and JK = JB + KB = 23. So the perimeter of triangle JKL is 20 + 17 + 23 = 60 units.

5 subtracted from 3 times a number x gives 7.

Answers

Answer:

3x-5=7

3x=7+5

x=12/3

x = 4

Answer:

Step-by-step explanation:

3 times a number x: 3*x = 3x

5 subtracted from  3x = 3x - 5

Equation: 3x - 5 = 7

Solution:

    Add 5 to both sides

3x - 5 + 5 = 7 + 5

         3x = 12

Divide both sides by 3

        3x/3 = 12/3

x = 4

A dozen donuts cost $2.99. To the nearest cent, what is the cost of 1 donut?

Answers

Answer:

that person is correct, each donut is only .25 cents because every 4 donuts are $1, multiply 4 by 3 and you get 12, 12=dozen. Since the total price is $3 it makes sense that each donut in .25 cents and every 4 donuts $1

HOPE THIS HELPS AND HOPE THIS MAKES SENSE!!!!!!!

If a dozen donuts cost $2.99 then the cost of one donut is approximately $0.25.

What is Division?

A division is a process of splitting a specific amount into equal parts.

Given that a dozen donuts cost $2.99.

We have to find the cost of 1 donut

As there are 12 donuts in a dozen, so to find the cost of one donut.

1 dozen donuts = 12 donuts.

One dozen donuts equal to twelve donuts.

To find the cost of 1 donut we need to divide the cost of a dozen by 12, because we are splitting the cost two point nine nine among twelve donuts.

$2.99 ÷ 12

Two point nine nine is divided with twelve we get zero point two five.

= $0.25

Therefore, the cost of one donut is approximately $0.25 to the nearest cent.

Answers

Answer:

Many options - 4/6 or 2/3 or 0.66

Step-by-step explanation:

When dividing fractions, we use KCF (keep, change, flip) so our new equation is 1/2 x 4/3. Just multiply! Your answer should be 4/6, and if it needs to be simplified, the answer is 2/3. The answer as a decimal is 0.66 !

Answer:You first would do 1/2 x 4/3 becuase when dividing numbers you use the keep change and flip method. So 1/2 you keep, you change the division sign into a multiplication sign and then 3/4 you flip into 4/3. After that you should have 1/2 x 4/3 and that gets you 4/6. So 4/6 would be your answer but simplified it would be 2/3. - Hope this helps!



Kaylee surveyed 920 of the students in her school about their favorite color. 95% said

their favorite color was blue. How many students' favorite color was blue?

Answers

Answer:

x = 874

Step-by-step explanation

Set up your equation like this: Part/whole = percent/100

Assign the variable x to the unknown part of the equation and add in the known numbers:

So in this situation it would be: x/920 = 95/100

Solve for x:

100 times X = 920 times 95. (cross multiply)

That leaves you with 100x = 87,400

Divide both sides by 100:

x = 874

X, Y and Z are partners in a firm in the ratio of 1/2 :1/3:1/6
Y retires from business and
X and Z purchase his share of profit in the ratio of 3:2. Find out new ratio ​

Answers

Answer:

6:2

Step-by-step explanation:

X share from old ratio is 1/2

Y share from old ratio is 1/3

Z share from old ratio is 1/6

Now, we are told Y retires and that X and Z purchase his shares.

Thus;

Amount X took from Y = 1/2 × 1/3 = 1/6

Amount Z took from Y = 1/6 × 1/3 = 1/18

Thus, new share of X is now; 1/6 + 1/2 = 2/3

New share of Z is now; 1/18 + 1/6 = 4/18 = 2/9

Ratio is now X:Z = 2/3 : 2/9 = 6:2
