Sally: 10h + 20

Jerry 9h + 50

h = hours

Answer:

Question 4: x = 106

Question 5: x = 118

Step-by-step explanation:

Question 4: The exterior angles of a triangle are going to add up to 360.

128 + 126 = 254

360 - 254 = 106

x = 106

Question 5: The exterior angles of a polygon add up to 360 (a quadrilateral is a polygon).

A right-angle = 90

90 + 34 = 124

360 - 124 = 236

236 / 2 = 118

x = 118

Answer:

Radius = 14 cm, Circumference = 88 cm

Step-by-step explanation:

d = 28 cm

r = 1 / 2 * 28

 = 14 cm

Circumference = 2πr

                         = 2 * 22 / 7 *  14

                         = 2 * 22 * 2

                         = 88 cm

Hope it helps :)

Answer:

Since QPR is an isoscelese triangle, QP and PR are congruent.

Therefore PR = 8

My guess for ST is z=1. So (5z = 5) and( 2z = 2). Then add 3 to 2 and you get 5. So ST = 5

Answer:

Step-by-step explanation:

[tex]\frac{3}{x+3}-\frac{4}{x-3}=\frac{3*(x-3)}{(x+3)(x-3)}-\frac{4(x+3)}{(x-3)(x+3)}\\\\=\frac{3*x-3*3}{(x+3)(x-3)}-\frac{4*x+4*3}{(x+3)(x-3)}\\\\=\frac{3x-9}{x^{2}-3^{2}}-\frac{4x+12}{x^{2}-3^{2}}\\\\=\frac{3x - 9 -(4x + 12)}{x^{2}-3^{2}}\\\\=\frac{3x-9-4x-12}{x^{2}-9}\\\\=\frac{-x-21}{x^{2}-9}\\\\[/tex]

[tex]\frac{3}{x+3}-\frac{4}{x-3}=\frac{5x}{x^{2}-9}\\\\\frac{-x-21}{x^{2}-9}=\frac{5x}{x^{2}-9}\\\\-x-21=\frac{5x}{(x^{2}-9)}*(x^{2}-9)\\[/tex]

-x - 21 = 5x

Add 'x' to both sides

-x -21 +x = 5x + x

        -21 = 6x

6x = -21

x = -21/6

   = -7/2

x = -3.5

Answer:

(x + 8) + (x + 8) + (x + 3) + (x + 3)

and

4x + 22

Two equivalent expressions to represent the perimeter of the boat dock are P = 2[(X + 8) +(X + 3)] or P = 4X + 22.

"A perimeter is a measurement of the outside of a shape. In order to find a perimeter, we have to find the sum of all the sides of the shape."

Given

Length of the dock = (X + 8) feet

Width of the dock = (x + 3) feet

A rectangle have length and width.

So the perimeter of the rectangle is 2(length + width)

Formula to find the perimeter of shape

Perimeter of the shape = Sum of all the sides of the shape

P = (X + 8) +(X + 3) + (X + 8) +(X + 3)

⇒ P = 2[X + 8 +X + 3]

⇒ P = 2[2X + 11]

⇒ P = 4X + 22

Hence, two equivalent expressions to represent the perimeter of the boat dock are P = (X + 8) +(X + 3) + (X + 8) +(X + 3) or P = 4X + 22.

Step-by-step explanation:

"cos" by itself is meaningless. It needs an argument.

cos(x°) = 5/36

x° = arccos(5/36) ≅ 82.2°

Answer:

D'(1,5)

Step-by-step explanation:

If you rotate a point 180 counter-clockwise around the origin, then it makes the x and y coordinates negative. In this case, it would make the coordinates positive because both coordinates are already negative. The answer would be D'(1,5).

Step-by-step explanation:

Answer:

The correct answer is = p = 15 and q = 6.

Step-by-step explanation:

Given:

Perimeter of rectangle = 42 cm

p - q = 9 cm

length = p

width = q

we know:

Perimeter of rectangle= 2(l+w)

solution:

42 = 2(P+q)

21= p+q

Difference of p and q = 9 cm.

Then, P+q=21 .... 1

P-q=9 ....2

Adding both 1 and 2

2P = 30

P= 15cm and

q = 15-9

= 6cm

Answer:

  a. 38

  b. 95

  c. 57

Step-by-step explanation:

In this context, you can consider "of" to mean "times." It can also be helpful to think of % as meaning /100.

a.  p = 20% × 190

  p = 20/100 × 190 = 38 . . . . you have 38 pennies

__

b. 190 = 200% × r

  190 = 200/100 × r . . . . replace % with /100

  190 = 2 × r . . . . . . . . . simplify the fraction

  190/2 = r = 95 . . . . you have 95 rare coins

__

c. n = 60% × r

  n = 60/100 × 95 = 57 . . . . you have 57 nickels

translate it 6 units to the left and 3 units up

Answer:

The coordinates of C are (15,16)

Step-by-step explanation:

As we can see, point C lies half the distance of AB

So we can use the midpoint formula to get the coordinates of C

we have this as:

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

(x1,y1) = (3,2)

(x2,y2) = (27,30)

Thus, we have

(x,y) = (3 + 27)/2, (30 + 2)/2

(x,y) = 30/2 , 32/2

(x,y) = (15,16)

Answer:

D. 25% decrease

Step-by-step explanation:

Since it's clear that they read less books to find how much it decreased we multiply 100 with 15 then divide it by 20

100 × 15 ÷ 20 = 75 this result shows a 25% decrease.

Answer:

  $50.40

Step-by-step explanation:

Adding the tax multiplies the amount by 1+8.1% = 1.081.

Adding the tip multiplies the amount by 1+17% = 1.17.

Then the amount with tax and tip is ...

  $39.85 × 1.081 × 1.17 = $50.40

The Smith family paid $50.40 for the meal.

Answer:

  (c)  h(x) = (3x +4)(2x +1)

Step-by-step explanation:

The answer choices differ in the values they create for the last two terms of the trinomial. The last term (+4) is created by all of the choices except the first one.

The middle term (11x) is only created by the third choice:

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

  = 6x^2 +3x +8x +4

  = 6x^2 +11x +4 . . . . matches the given h(x)

Answer:

1/ -6=12+1/3a

Rewrite the equation as 12+1/3a=−6.

12+1/3a= −6

Combine 1/3 and a.

12+a/3= −6

Move all terms not containing a to the right side of the equation.

a/3= −18

Multiply both sides of the equation by 3.

3⋅a/3=3⋅ −18

Simplify both sides of the equation.

a= −54

2/ -6 =12 -1/3a

Rewrite the equation as 12−13a=−6.

12−1/3a=−6

Combine a and /13.

12−a/3=−6

Move all terms not containing a to the right side of the equation.

−a/3=−18

Multiply both sides of the equation by −3.

−3⋅(−a/3)=−3 ⋅−18

Simplify both sides of the equation.

a=54
