38. Find the value of x in isosceles trapezoid ABCD.
Given: AC = 3x - 16 and BD = 10x-86

Answer:

1, 4, 3, 5, 6

Step-by-step explanation:

5(5x² - 9x) = 45x + 40 ← distribute parenthesis on left side

25x² - 45x = 45x + 40 ← subtract 45x + 40 from both sides

25x² - 90x - 40 = 0 ← factor out 5 from each term

5(5x² - 18x - 8) = 0

5(x(5x + 2) - 4(5x + 2))

5(x - 4)(5x + 2)

Answer:

The order is: 1, 4, 3, 5, 6

Step-by-step explanation:

5(5x² - 9x) = 45x + 40

25x² - 45x = 45x + 40

25x² - 90x - 40 = 0

5(5x² - 18x - 8) = 0

5(x(5x + 2) - 4(5x + 2)

5(x - 4)(5x + 2)

The order is: 1, 4, 3, 5, 6

Answer:

The axis of symmetry of this parabola will be the line x=−b2a .

Step-by-step explanation:

Graph the parabola y=x2−7x+2 .

Compare the equation with y=ax2+bx+c to find the values of a , b , and c .

Here, a=1,b=−7 and c=2 .

Use the values of the coefficients to write the equation of axis of symmetry .

The graph of a quadratic equation in the form   y=ax2+bx+c has as its axis of symmetry the line x=−b2a . So, the equation of the axis of symmetry of the given parabola is x=−(−7)2(1) or x=72 .

Substitute x=72 in the equation to find the y -coordinate of the vertex.

y=(72)2−7(72)+2    =494−492+2    =49 − 98 + 84     =−414

Therefore, the coordinates of the vertex are (72,−414) .

Answer:

[tex]\huge\boxed{\sf y = 3}[/tex]

Step-by-step explanation:

Given Equation:

4 + 3y = 6y - 5

Add 5 to both sides

4 + 5 + 3y = 6y

9 + 3y = 6y

Subtract 3y to both sides

9 = 6y - 3y

9 = 3y

Divide 3 to both sides

3 = y

y = 3

Answer:

a²+b²=c² so you take 15² =225. then you take 8²=64 then you add 225+64=289. Then you find the √289 That equals 17

Explanation:

The key thing to focus on is the phrasing "starting at the age of 8"

Specifically, your teacher wants the starting height when Mia was 8 years old. That height being 52 inches.

The 7 inches refers to how much she had grown over the 2 years, which is part of the rate of change (and will be part of the slope).

Side note: 52 inches = 4 ft, 4 inches

Answer:

28

Step-by-step explanation:

2*28 = 56

3*28 = 84 -10 = 74

74+56+50 = 180

180 degrees in a triangle

Answer:

$1107.55

Step-by-step explanation:

3,589.90 x .0590/12 = $17.65

3,589.90 + 17.65 =3,607.55

3,607.55 - 2,500 = $1,107.55

Answer:

Answer will be zero , since the value of x and y are zero and any value multiply with zero will be zero only .

Answer:

x = 110

y = 102

z = 82

Step-by-step explanation:

Angles that create a line are equal to 180

x + 70 = 180

x = 110

y + 78 = 180

y = 102

A quadrilateral's angles add up to 360

110 + 78 + 90 + z = 360

278 + z = 360

z = 82

About 112 students eat lunch 4th period

Step-by-step explanation:

250*.45 = 113

112.5 rounded is 112 because there can not be any half students

This is because there are 3 red + 5 yellow = 8 non-blue marbles out of 3+4+5 = 12 total. This leads to the fraction 8/12 and it reduces to 2/3.

Answer:

Step-by-step explanation:

Because nintendo price=300$

He has 215$

1 chore he does=7$

Meaning if he did 10 chores he get's 70$ added so he did 10 now he has 285$ If he does 2 more chores that is 14$ more added.

So he now has 299$ so he done 12 chores and he needs 1 more dollar so if he did 1 more he gets 306$ and that was the least amount of chores he could do if he wanted 300$

And there's your answer

The monthly cost for 17 hundred of cubic feet is $52.13.

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the bill paid for x HCF of water.

The slope is 1.45, hence m = 1.45.

The monthly cost for 13 HCF is $46.33, hence:

46.33 = 1.45(13) + b

b = 27.48

y = 1.45x + 27.48

For 17 HCF:

y = 1.45(17) + 27.48 = 52.13

The monthly cost for 17 hundred of cubic feet is $52.13.

Answer: C

Step-by-step explanation:

I would solve this by calculating the percentage of dislikes that makes up to this amount of likes:

First one, "The True Science of Parallel Universes" would be:

5/300)*100 = 1.66

Second one, "did the Past Really Happen?" would be:

7/400)*100 = 1.75

The first one has less dislikes compared to likes. So "The True Science of Parallel Universes" is the video that is better liked

Since, Marie has $60,000 in a savings account that earns 7% interest per year.

Find: How much will she have in 4 months.

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: solution[/tex]

Step 1: Find the money for the 7% rate

=> [tex] 60000 \times \frac{7}{100} [/tex]

=> [tex] \frac{60000}{1} \times \frac{7}{100} [/tex]

cancel the two zeros of 60,000 and 100

=> 600 × 7

=> 4,200

Add 4,200 to 60,000

=> 64,200

per year = 64,200

Now, divide 64,200 by 12

since 12 months to make one year

=> 64,200 ÷ 12

=> 5,350

now multiply it by 4 months she gets 5350 per month

=> 21,400

Answer:

4 1/4 in.

Step-by-step explanation:

Highest record: 24 ft. 6 3/4 in.

John's best long jump: 24 ft. 2 1/2 in.

convert 1/2 to have denominator of 4...

1/2 x 2/2=2/4

subtract from highest record...

3/4-2/4=1/4

add to whole numbers...

6-2=4

4+1/4= 4 1/4
