The original price of a pair of shoes is $45. The sale price is 20% off the original price. What is the amount off of the original price?

Answer: $40.50

Step-by-step explanation:

Since 15% of his total earnings was from raking leaves. The earning from taking leave will be:

= 15% × $90

= 0.15 × $90

= $13.50

Earnings from mowing lawns = $36

The earnings from walking dogs will be:

= $90 - $36 - $13.50

= $40.50

Answer:

The slope of the line is 2.

Step-by-step explanation:

you can simply do this by using the method rise/run. You count how much it takes to get from one point to the other. Go Upwards twice and to the right once which gives you 2/1 which is 2.

Answer:

The average speed of the train = 30 miles per hour

Step-by-step explanation:

Given

To determine

what is its average speed?

The average speed of the train can be calculated using the formula

Average Speed = Total Distance / Total time

                           =  270 / 9

                           = 30 miles per hour

Therefore, the average speed of the train = 30 miles per hour

Answer:

a² + 5a - 8

Step-by-step explanation:

If the construction paper has a length of a² + 7a - 3, and Katelyn cut a piece 2a + 5 long, the amount of construction paper that would be left is,

a² + 7a - 3 - (2a + 5)

= a² + 7a - 3 - 2a - 5

collecting like terms, we have

= a² + 7a - 2a - 3 - 5

simplifying, we have

= a² + 5a - 8

Answer:

Step-by-step explanation:

Answer:

by phythagoras theorem

(c+b)^2=(8)^2+(6)^2

(b+c)^2=64+36

(b+c)^2=100

b+c=√100

b+c=10.

by phythagoras theorem

(8)^2=(a)^2+(b)^2

64-b^2=a^2. {1}

by phythagoras theorem

(6)^2=(a)^2+(c)^2

36-c^2=a^2. {2}

In equation 1 and 2,

64-b^2=36-c^2

64-36= -c^2+b^2

28= b^2-c^2

28=(b+c)(b-c)

28=10(b-c)

b-c=28/10

b-c=2.8.

b+c=10

b-c=2.8

subtract both equations

c=3.6

option A is correct.

Answer:

5p-5

Step-by-step explanation:

Answer: See explanation

Step-by-step explanation:

Slope = 4 - 3 / 0 - (-4) = 1/4

Slope = 1/4

Point slope form: y - y₁ = m (x - x₁)

y₁ = 3

x₁ = -4

y - 3 = 1/4 ( x - [-4])

y - 3 = 1/4 (x + 4)

y - 3 = 1/4x + 1

Add 3 to both sides

y = 1/4x + 4

Standard Form: Ax + By = C

Point slope form- y = 1/4x + 4

Standard form:

y = 1/4x + 4

Subtract 1/4x from both sides

-1/4x + y = 4      or   1/4x - y = -4

Slope intercept form: y = mx + b

m = 1/4

y-intercept = 4

y = 1/4x + 4

Hope this helped!

Answer:

The answer to the question is A

Answer:

40

Step-by-step explanation:

(2x+1/(2x))^5 *(2x -1/(2x))^5

= ((2x)^2 -1/(2x)^2)^5 (a+b)*(a-b) =a2-b2

= (4x^2-1/4(x)^2)^5

now

x =4x^2. ,a = 1/4(x)^2 ,n =5

we have

general term = Cr *x^r *a^(n-r)

= Cr * (4x^2)^r * (1/4(x)^2)^(n-r)

= Cr *4^r * X^2r * 1/( 4^(n-r) *x^(2n-2r)

= Cr * 4^r/4^(n-r) * x^(2r)/x^(2n-2r)

= Cr * 4(2r-n) *x(4r-2n)

now for x^2

4r-2n = 2

4r -10=2

4r =12

r = 3

now for coeff

C(5,3) * 4^(2*3-5)

5!/(3!*(5-3)!) * 4

5*4/(2*1)*4

The number of times getting 6's, when the dice is rolled 600 times is 100.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, the dice is rolled 600 times.

If you roll a fair, 6-sided die, there is an equal probability that the die will land on any given side. That probability is 1/6. This means that if you roll the die 600 times, each face would be expected to appear 100 times.

Therefore, number of times getting 6's, when the dice is rolled 600 times is 100.

Answer:

m∠1 is 49° and m∠3 is 49°

Step-by-step explanation:

In the given figure

∵ There are 2 parallel lines

∵ A transversal cuts them

∴ ∠4 and ∠8 are corresponding angles

→ Corresponding angles are equal in measures

∴ m∠4 = m∠8

∵ m∠8 = 131°

∴ m∠4 = 131°

∵ ∠1 and ∠4 formed a pair of linear angle

∵ The sum of the measures of the linear angles is 180°

∴ m∠1 + m∠4 = 180°

→ Substitute ∠4 by 131°

∴ m∠1 + 131° = 180°

→ Subtract 131 from both sides

∵ m∠1 + 131 - 131 = 180 - 131

∴ m∠1 = 49°

∵ ∠1 and ∠3 are vertically opposite angles

∴ m∠1 = m∠3

∵ m∠1 = 49°

∴ m∠3 = 49°
