Step-by-step explanation:

Answer:

Vertex angle = 124°

Step-by-step explanation:

m<BAC = m<BCA (base angles of isosceles ∆ are congruent)

7x + 1 = 5x + 9

Collect like terms

7x - 5x = -1 + 9

2x = 8

divide both sides by 2

x = 4

Vertex angle = 180 - ((7x + 1) + (5x + 9)) (sum of triangle)

Plug in the value of x

Vertex angle = 180 - ((7*4 + 1) + (5*4 + 9))

Vertex angle = 180 - (29 + 29)

Vertex angle = 124°

Answer:

B Barney stops less than a foot from the car.

Step-by-step explanation:

From the information given:

The initial speed of barney [tex]v_o[/tex] = 25 mph

Coefficient of friction [tex]\mu[/tex] = 0.7

Recall that

1 mph = 0.447 m/s

Then

[tex]v_o[/tex] = 25 × 0.447 m/s

[tex]v_o[/tex] = 11.175 m/s

The force of friction acting on the barney is expressed as:

[tex]F = \mu N \\ \\ F = \mu mg[/tex]

[tex]ma = \mu mg[/tex]

[tex]a = \mu g[/tex]

a = 0.7 × 9.8 m/s

a = 6.86 m/s²

Since the force acts in an opposite direction to the motion of Barney, Thus the acceleration must also be negative.

a = -6.86 m/s²

Now;

Suppose Barney stops after traveling a  distance (s), so that the final speed is zero.

Then;

Using the kinematic equation;

[tex]v^2 - v_o^2 = 2as[/tex]

[tex]0 - (11.17)^2 = 2 \times (-6.86) s[/tex]

[tex]-124.76 = -13.72 s[/tex]

[tex]s = \dfrac{124.76}{13.72}[/tex]

s = 9.09 m

Recall that;

1 m = 3.28 ft

So;

s = 9.09 m = 9.09 × 3.28 ft

s = 29.81 ft

∴

The distance traveled by the Barney is 29.81 ft which implies that Barney stops less than a foot from the car.

Answer: 33 1/3%

Step-by-step explanation:

Percentage increase of the shirt will be calculated as:

= Price Increase / Old price × 100%

Price Increase = $20 - $15 = $5

Old price = $15

Percent increase = Price Increase / Old price × 100%

= 5/15 × 100

= 1/3 × 100

= 33 1/3%

Answer:

it would be -25% because 15 is less than 20

Answer:

$88 in total

Step-by-step explanation:

x = number of hours

y = total cost to rent the snowboard.

$25 is already guaranteed

25 + 15.75x = y

since it is 4 hours from 8:30 a.m. to 12:30 a.m. you put 4 into x.

25+15.75(4) = y

88 = y

Answer:

69

Step-by-step explanation:

4x3=12

9x5=45

2x6=12

45+12+12=69

Answer:

x = 5

Step-by-step explanation:

The interior angles of a triangle always have to add up to 180 degrees.

This means you can form an equation with the three angles you have:

(10x - 4) + (8x + 3) + 91 = 180

Then, solve:

[tex]10x-4+8x+3+91=180[/tex]

combine like terms

[tex]18x+90=180[/tex]

subtract 90 from both sides

[tex]18x = 90[/tex]

divide both sides by 18

[tex]x = 5[/tex]

Answer:

6^5 or 6 to the power of 5

Step-by-step explanation:

This is because 6*6 is 36 which is equal to 6^2  and 6*6*6 is 6^3   6*6*6*6 is 6^4 and finally we have 6*6*6*6*6 which is 6^5.

sorry guys i need points lol

Answer:

Angle x would be 87 degrees.

Step-by-step explanation:

Angles inside of a triangle add up to 180 degrees. So 51+42=93 and if you subtract 93 from 180, you get 87.

Answer:

PLATO / EDMENTUM :)

Step-by-step explanation:

Answer:

2.5

Step-by-step explanation:

The minimum value is the minimum y-value a function includes. In this case, since you can see the function is periodic (it repeats itself periodically, hence periodic) and the smallest y-value the function encounters is 2.5 (doesn't go below this value), the minimum y-value is 2.5. I hope this made sense. If not, feel free to let me know.

Answer:

x=-5

Step-by-step explanation:

25 - 3x = 40

-3x + 25 =40

-3x +25--25=40-25

-3x=15

-3x÷-3=25÷-3

x=-5

Answer:

not a function

Step-by-step explanation:

not a function because the x value repeats twice in x=3

Answer:

Not a function

Step-by-step explanation:

A function can't be a dot graph, and it also needs a stronger pattern.

Answer:

3

Step-by-step explanation:

3 is the slope. Since it is y/x, then it is 9/3, which is simplified to 3/1.
