Answer:

Function 2, because Steve spends $5 each week and Ada spends $4 each week

Step-by-step explanation:

Function 1 shows a rate of change of using two points

(x1, y1) = (40,1)

(x2,y2) = (36,2)

m = (y2-y1)/(x2-x1) = (36-40)/(2-1) = -4

The rate of change is decreasing or spending at $4 per week

Function 2 shows an equation y=mx+b; where m is the slope or the rate of change

m=-5

The rate of change is decreasing or spending at $5 per week

Answer: its C

Function 2, because Steve spends $5 each week and Ada spends $4 each week

Answer:

[tex]\huge\boxed{\sf 126\° \ OR \ 145 \°}[/tex]

Step-by-step explanation:

m∠4 + m∠7 = 180    (Adjacent Angles of a parallelogram)

Given that m∠4 = x + 45, m∠7 = x² + 45

x + 45 + x² + 45 = 180

x² + x + 90 = 180

x² + x = 180 - 90

x² + x = 90

x² + x - 90 = 0

Using mid-term break formula

x² + 10x - 9x - 90 = 0

x(x+10) - 9(x+10) = 0

(x - 9)(x + 10) = 0

Either,

x-9 = 0       OR      x+10 = 0

x = 9          OR        x = -10

[tex]\rule[225]{225}{2}[/tex]

Now,

m < 7 = x² + 45

For x = 9

m < 7 = (9)² + 45

m < 7 = 81 + 45

For x = -10

m < 7 = (-10)² + 45

m < 7 = 100 + 45

Answer:

75

Step-by-step explanation:

125 × 0.40 = 50

125 - 50 = 75

Decrease number by 40% of its value.

Percentage decrease = 40% × 125

New value

125 - Percentage decrease

125 - (40% × 125)

125 - 40% × 125

(1 - 40%) × 125

(100% - 40%) × 125

60% × 125

60 ÷ 100 × 125

60 × 125 ÷ 100

7,500 ÷ 100

=75

Answer:

The shadow of the windmill will be 24 yards long

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ A bell tower that is 60 yards tall casts a shadow 32 yards long

∴ The tall = 60 yards and the shadow = 32 yards

∵ A windmill is  45 yards tall

∴ The tall = 45 yards

→ By using the ratio method

→ Tall  :  Shadow

→  60   :  32

→  45   :  x

→ By using the cross multiplication

∵ x × 60 = 45 × 32

∴ 60x = 1440

→ Divide both sides by 60

∵ [tex]\frac{60x}{60}=\frac{1440}{60}[/tex]

∴ x = 24

∴ The shadow of the windmill will be 24 yards long

Answer:

a. angle 6 and angle 7

b. angle 6 and angle 8

c. angle 3 and angle 1

Step-by-step explanation:

linear pair is two angles that share a base and and add up to 180

vertical angles is the pair of opposite angles formed by two intersecting lines

congruent is the same measure

Answer:

see explanation

Step-by-step explanation:

(a)

A linear pair of angles, are adjacent to each other and sum to 180°

There are 8  linear pairs in the diagram, they are

1 and 2 / 2 and 3 / 3 and 4 / 4 and 1 / 5 and 6 / 6 and 7 / 7 and 8 / 8 and 5

(b)

There are 4 vertical angles in the diagram

1 and 3 / 2 and 4 / 5 and 7 / 6 and 8

Note that vertical angles are congruent

Other congruent angles are

2 and 6 / 3 and 7 / 1 and 5 / 4 and 8 ( All corresponding angles )

4 and 6 / 3 and 5 ( are Alternate angles )

(6) QP = QR therefore, triangle QPR is an isosceles triangle.

Since QPR is an isosceles triangle, the base angles are equal.

angle P + angle R + 80 = 180

2x + 80 = 180

2x = 100

x = 50.

That is just the measure of the base angle.

Now take triangle TSR.

Since R = 50, due to angle sum property, we can come up with this equation:

50 + 85 + x = 180

x = 180 - 135

x = 45 <- That's the answer.

(8) Take triangle PSQ, you get angle P = 70 degrees using the angle sum property and algebra.

Now take triangle PSR and you get angle P in the triangle as (180 - 100) / 2 = 40.

Since P = 70, and P in the smaller triangle is 40, 70 - 40 would be the answer.

x = 30 degrees <- That's the answer :D

Answer:

The value of one box in the tape diagram will be 21 square feet

Step-by-step explanation:

Here, we have the total ratio added as 4 + 3 + 2 = 9

So the area of one box on the tape diagram will be the combined area divided by the total square feet

Mathematically, that will be;

189 square feet/9 = 21

Answer:

y - 2 = 3 (x - 4) - Point-Slope form.

y = 3x - 10 - Slope-intercept form.

Step-by-step explanation:

I will solve by using the formula:

y - y1 = m (x - x1)

Substitute:

y - 2 = 3 (x - 4)

This is the answer written in point-slope form.

I will put it into slope-intercept form.

Distribute:

y - 2 = 3x - 12

add 2 to both sides:

y = 3x - 10

Point (4 , 2) with a slope of 3 as an equation written in slope-intercept form looks like:

y = 3x - 10

The equation in point-slope form is y = 3x - 10 for the line that passes through the point at (4,2) with the given slope m=3.

The slope of a line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

Given that line that passes through the point at (4,2)

Let the equation in point-slope form would be

⇒ y - y₁ = m(x -x₁ )

Here, slope m = 3, x₁ = 4 and  y₁ = 2

Substitute the values in the equation, and we get

⇒ y - 2 = 3 (x - 4)

⇒ y - 2 = 3x - 12

Add 2 to both sides of the equation

⇒ y = 3x - 10

Hence, the equation in point-slope form is y = 3x - 10 for the line that passes through the point at (4,2) with the given slope m = 3.

Given:

Amount deposited on birth = $10,000.

Interest rate = 5% compound quarterly.

To find:

The balance on the person's 18th birthday.

Solution:

The formula for amount is

[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]

where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.

Substitute P=10000, r=0.05, n=4, t=18 in the above formula.

[tex]A=10000\left(1+\dfrac{0.05}{4}\right)^{4(18)}[/tex]

[tex]A=10000\left(1+0.0125\right)^{72}[/tex]

[tex]A=10000\left(1.0125\right)^{72}[/tex]

[tex]A=24459.2026814[/tex]

[tex]A\approx 24459.20[/tex]

Therefore, the balance on the person's 18th birthday is $24459.20.

Answer: No. It's not proportional

Step-by-step explanation:

The direct proportion in mathematics is expressed as:

y = kx

where

y = $200

k = constant

x = $7.50

We then solve for k

y = kx

200 = 7.50k

k = 200/7.50

k = 26.67

Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.
