Step-by-step explanation:

Answer:

x = 8

z = 86

Step-by-step explanation:

6x + 46 = 13x - 10        (Because they're vertical angles)

6x - 13x = -10 - 46

-7x = -56

x = 8

6x + 46

6(8) + 46

94

z + 94 = 180

z = 86

Answer:

45 points

Step-by-step explanation:

Average= sun of all numbers/ no. of numbers

33= (23+35+27+48+18+35+x)/7

33= 186+x/7

33×7= 186+ x

231= 186+x

x= 231- 186

x= 45

Answer:

45 points, he scored 45 points in game 7

Step-by-step explanation:

Right now, the average, or mean, is (23 + 35 + 27 + 48 + 18 + 35)/6 = 31

The number plus 23 + 35 + 27 + 48 + 18 + 35 and then divided by 7 should equal 35, that number is 45

(23 + 35 + 27 + 48 + 18 + 35 + 45)/7 = 33 = 231/7 = 33 = 33 = 33

To find the mean, you add all the numbers and then divide it by the amount of numbers there.

Answer:

d ≈ 1732 ft

Step-by-step explanation:

Angle of elevation = Angle of depression

Following this truth,

m∠PAQ (Angle of depression) = m∠APB (Angle of elevation) = 30°

By applying tangent rule in the given triangle ABP,

tan(30°) = [tex]\frac{AB}{PB}[/tex]

[tex]\frac{1}{\sqrt{3}}=\frac{1000}{d}[/tex]

d = 1000√3

d = 1732.05

d ≈ 1732 ft

Answer:

16 Miles/Hours

Step-by-step explanation:

Average speed is the total distance covered divided by the total time

In that case we have a distance of 4 miles

Time is 15 minutes and in order to convert from minutes to hours we divide by 60 and it becomes 0.25 hours

So 4/0.25 is 16 Miles/Hours

Answer:

3

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

Answer:

The mistake they made was they switched the slope and y-intercept.

The correct answer is y=2x+7 because when we write an equation in slope intercept form (y=mx+b) you replace m with the slope and b with the y-intercept.

Hope this helps! <3

Answer:

Find the solutions below

Step-by-step explanation:

Given the equation

y = -x^2 + 2x + 7

y = -2x+2

Equating both expressions

-x^2 + 2x + 7 = -2x + 2

-x^2 + 2x + 7 + 2x - 2 = 0

-x^2 + 4x + 5 = 0

Multiply through by -1

x^2 - 4x - 5 = 0

Factorize

x^2 - 5x + x - 5 = 0

x(x-5)+1(x-5) = 0

(x+1)(x-5) = 0

x+1 = 0 and x - 5 = 0

x = -1 and 5

when x = -1

y = -2x+2

y = -2(-1)+2

y = 2+2

y = 4

when x = 5

y = -2(5)+2

y = -10+2

y = -8

Hence the solutions are (-1, 4) and (5, -8)

b) y = x^2-3x-27

y = x - 6

Equating both expressions

x^2-3x-27 = x - 6

x^2-3x-27 - x + 6 = 0

x^2-4x-21 = 0

x^2 - 7x + 3x - 21 = 0

x(x-7)+3(x-7) = 0

(x+3)(x-7) = 0

x = -3 and 7

when x = -3

y = -3-6

y = -9

when x = 7

y = 7 - 6

y = 1

Hence the required solutions are (-3, -9) and (7, 1)

Answer:

Equation B, 10 + 5.50n = y.

Step-by-step explanation:

N is the pounds of shrimp that were purchased. This has no set value, it can change at any time.

Since each pound of shrimp is $5.50, if you wanted to buy 10 pounds of fish you'd pay $55.

If I wanted to write an equation to find the total amount of money that I'd need to pay for n pounds of shrimp, I would use the equation 5.50n. (I don't know if this makes sense lol I'm terrible at explaining ;-;)

Now, it states that he wants an extra 10 dollars to pay for expenses. On top of the 5.50n, he wants an extra $10.

You need to add 10 to 5.50, in order to get the total amount, or y.

The final equation is going to be 5.50n + 10 = y, or choice B.

Answer:

1-    10% of -80 is -8.  

2-    28 is 4% of 700.

3-   25% of a number is equal to 1/4 or 0.25 of it.

4-    13% of a number is equal to 0.13 of it.

5-    15 is 12.5% of 120.

Step-by-step explanation:

1. 10% of ________- 8

2.28 is 4% of _________

3.25% of ________

4.13% of______

5.15 is 12.5% of _____

To determine the missing numbers in the statements, the following calculations must be performed:

1-

10 = -8

100 = X

100 x -8 / 10 = X

-800 / 10 = X

-80 = X

Therefore, 10% of -80 is -8.

two-

4 = 28

100 = X

100 x 28/4 = X

2800/4 = X

700 = X

Therefore, 28 is 4% of 700.

3-

25% of a number is equal to 1/4 or 0.25 of it.

4-

13% of a number is equal to 0.13 of it.

5-

12.5 = 15

100 = X

100 x 15 / 12.5 = X

1500 / 12.5 = X

120 = X

Therefore, 15 is 12.5% of 120.

3x + 24 = 180

3x = 180 - 24

3x = 156x = 156/3

x=52

Answer: D) 14.3%

Step-by-step explanation:

Conditional probability formula:

[tex]P(B |\text{given that A}) =\dfrac{P(A\ and\ B)}{P(A)}[/tex]

So, The probability he or she was dissatisfied, given that he or she had hip surgery = [tex]\dfrac{\text{Number of persons are dissatisfied and has hip surgery}}{\text{Total persons have hip surgery}}[/tex]

From the table, the number of persons who are dissatisfied and has hip surgery = 15

Total persons have hip surgery = 105

Required probability = [tex]\dfrac{15}{105}\approx0.143[/tex]

In percent, Required probability = 14.3%

Correct option D) 14.3%

Answer:

The slope is just 2/3 and the y intercept is (0,3)

Given:

The x and y axis are tangent to a circle with radius 3 units.

To find:

The standard form of the circle.

Solution:

It is given that the radius of the circle is 3 units and x and y axis are tangent to the circle.

We know that the radius of the circle are perpendicular to the tangent at the point of tangency.

It means center of the circle is 3 units from the y-axis and 3 units from the x-axis. So, the center of the circle is (3,3).

The standard form of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where, (h,k) is the center of the circle and r is the radius of the circle.

Putting [tex]h=3,k=3,r=3[/tex], we get

[tex](x-3)^2+(y-3)^2=3^2[/tex]

[tex](x-3)^2+(y-3)^2=9[/tex]

Therefore, the standard form of the given circle is [tex](x-3)^2+(y-3)^2=9[/tex].

I think its answer B) B
