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]

[tex]1\frac{2}{3}[/tex]

Step-by-step explanation:

The slope of a line is the change in a line, or the, [tex]\frac{rise}{run}[/tex] in a line. One can find the slope of a line using the formula,

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

30

Step-by-step explanation:

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:

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.

Answer:

The war started mainly because of four aspects: Militarism, Alliances, Imperialism and Nationalism. This is because big armies become potential threats to other countries, other countries started forcing alliances in order to secure land. ... The overall cause of World War was the assassination of Archduke Franz Ferdinand.

Step-by-step explanation:

Answer:

B)

15 ≥ 3x + y

8 ≥ x + y

Step-by-step explanation:

Strawberries= 3x

Blueberries= y

At least symbol= ≥

15 ≥ 3x + y (Plans to spend AT LEAST $15 so this has to be 15 ≥)

8 ≥ x + y (Plans to spend  AT LEAST 8 pints so this has to be 8 ≥)

The required, system of inequalities can be used to determine the number of pints of strawberries are 3x + y ≥ 15 and x + y ≥ 8. Option A is correct.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
Since Sonya plans to spend at least $15 on berries and strawberries are on sale for $3 per pint, the cost of buying x pints of strawberries would be 3x dollars. Similarly, the cost of buying y pints of blueberries would be y dollars since they are on sale for $1 per pint. Therefore, we have:

3x + y ≥ 15 (Sonya plans to spend at least $15)

x + y ≥ 8 (Sonya plans to buy at least 8 pints of berries)

So the system of inequalities that can be used to determine the number of pints of strawberries, x, and the number of pints of blueberries, y, that Sonya should buy is:

A) 3x + y ≥ 15

x + y ≥ 8

So, option A is the correct answer.

#SPJ2

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: 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

Step-by-step explanation:

Radius = half the diameter = AB/2

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:

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, y) = (7, -1)

Step-by-step explanation:

The expression for x makes it easy to use that for substitution.

  3(-7y) +y = 20

  -20y = 20 . . . . . collect terms

  y = -1 . . . . . . . . . divide by -20

  -7(-1) = x = 7 . . . use y in the second equation to find x

The solution is (x, y) = (7, -1).

Answer:

the answer

the ratio x:y is 25:18

Step-by-step explanation:

we know that

the length of Q is 25% more than the length of p

so

length Q=1.25*40--------> 50 cm

the area of Q is 10% less than the area of p

Area Q=50*y

Area P=40*x

so

50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18
