Answer:

d)  XY = 15.75

Step-by-step explanation:

XY is the median of the trapezoid

XY = (DC + AB) ÷ 2

XY = (13.4 + 18.1) / 2

Answer:

9, 13, 17

Step-by-step explanation:

The difference between the greatest value and the least is 8, the range.

Add the three numbers to total 39, then divide by 3 to get the mean, 13.

3(x - 2) + 1 = 2(x - 4) + x + 13

3x - 6 + 1 = 2x - 8 + x + 13

3x + 7 = 3x + 5

3x + 7 = 3x + 5

Answer:

The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5

Step-by-step explanation:

Let

x ------> the number of pounds of apples

(x-2) -----> the number of pounds of grapes

we know that

Solve for x

so

therefore

The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5

Answer:

4.5 pounds of apples

2.5 pounds of grapes

Step-by-step explanation:

a = # of apples

(a - 2) = # of grapes

1.68a + 2.48(a - 2) = 13.76

1.68a + 2.48a - 4.96 = 13.76

4.16a = 18.72

a = 4.5; Apples

(a - 2) = 2.5;  Grapes

Answer:

x=14

Step-by-step explanation:

x-4=⅓(6x-54)

x-4=2x-18

x+14=2x

x=14

Answer:

14

Step-by-step explanation:

STEP1:

1 Simplify — 3

Equation at the end of step1:

1 (x - 4) - (— • (6x - 54)) = 0 3

STEP2:

STEP3:Pulling out like terms

 3.1     Pull out like factors :

   6x - 54  =   6 • (x - 9) 

Equation at the end of step3:

(x - 4) - 2 • (x - 9) = 0

STEP4:Equation at the end of step 4

14 - x = 0

STEP5:

Solving a Single Variable Equation:

 5.1      Solve  :    -x+14 = 0 

 Subtract  14  from both sides of the equation : 

                      -x = -14

Multiply both sides of the equation by (-1) :  x = 14

Answer:

z = 5

Step-by-step explanation:

m = ∆y/∆x = y₂-y₁/x₂-x₁

0 = y₂-y₁/x₂-x₁ = 5 - z / -7 - 9 = 5 - z / -16 →

5 - z / -16 = 0 → 5 - z / -16 × -16 = 0 × -16 → 5 - z = 0 →

5 - z - 5 = 0 - 5 → -z = -5 → z = 5

Answer:

1500/100 x 4 = 60

60 X 5 = 300

interest earned $ 300

total balance $1800

Answer:

x,x+1,x+2

Step-by-step explanation:

x+2[x+1]+3[x+2]= -76

x+2x+2+3x+6= -76

6x+8=-76

6x=-76-8

6x= -84

x= -84/6

x= -14

Is the square root of 64 rational or irrational? The square root of 64 is a rational number if 64 is a perfect square. It is an irrational number if it is not a perfect square. Since 64 is a perfect square, it is rational number. This means that the answer to "the square root of 64?" will have no decimals. √ 64 is a rational number

simple version:yes its rational

Answer:

2.79

Step-by-step explanation:

Given

With reference angle 21°

hypotenuse (h) = 3

base (b) = x

Now

cos 21° = b / h

0.93 = x / 3

x = 0.93 * 3

x = 2.79

Answer:

180 dollars

Step-by-step explanation:

if it was discounted by 30 percent, that means 126 is 70 percent of the orin=inal price. If you divide 126 by 70, you get 1.8 is the money worth 1 percent. Multiply 1.8 by 100 to get the original price, and you end up with 180 dollars.

Complete question is;

A cash register contains coins. 10 pennies, 11 nickels, 13 dimes, and 6 quarters. A cashier will randomly choose two coins one at a time without replacement. What is the probability that the cashier will choose a penny first, followed by a dime?

Answer:

1/12

Step-by-step explanation:

We are told there are 10 pennies, 11 nickels, 13 dimes, and 6 quarters.

Thus total number of coins = 10 + 11 + 13 + 6 = 40 coins

Probability of picking a penny first is;

10/40 = 1/4

After which we will have 39 coins left.

Probability of a dime after that will be 13/39 = 1/3

Thus,probability of picking a penny first then a dime will be; ¼ × ⅓ = 1/12
