Hadi earned $120.00 from his job yesterday. Today he expects to earn 15% less than yesterday and tomorrow he expects to earn 15% more than today. What is the combined amount Hadi expects to earn for three days

Answers

Yesterday Hadi earned: $120

Today he will earn: $120*85% = $102
(You times the amount yesterday by 85% because you want to find the 15% less of 100% of the amount he's earned yesterday. Therefore, to find 15% less than yesterday you multiply it by 85% (100% - 15%) )

Tomorrow he will earn: $102*115% = $117.30
(Same thing here, however you are finding 15% more than 100% today. Therefore, you multiply the amount he earned today it by 115% (100% + 15%) )

To find the amount he earns for the three days you must add the amount earned of yesterday, today and tomorrow earned from the working above.

Therefore, Hadi expects to earn:
Yesterday + Today + Tomorrow = 120 + 102 + 117.30 = $339.3
Yesterday Hadi earned: $120

Today he will earn: $120*85% = $102
(You times the amount yesterday by 85% because you want to find the 15% less of 100% of the amount he's earned yesterday. Therefore, to find 15% less than yesterday you multiply it by 85% (100% - 15%) )

Tomorrow he will earn: $102*115% = $117.30
(Same thing here, however you are finding 15% more than 100% today. Therefore, you multiply the amount he earned today it by 115% (100% + 15%) )

To find the amount he earns for the three days you must add the amount earned of yesterday, today and tomorrow earned from the working above.

Therefore, Hadi expects to earn: 
Yesterday + Today + Tomorrow = 120 + 102 + 117.30 = $339.3

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.A triangle has 2 congruent sides. The angle between the 2 congruent sides is labeled x. The angles opposite of the 2 congruent sides each measure 65 degrees.


Find the measure of x in the triangle. Show all your work.

Answers

Answer:

Therefore,

Measure of x is 50°.

Step-by-step explanation:

Given:

Let name the Triangle as ΔABC,as shown in the Figure below ,such that

AB ≅ AC    ..... triangle has 2 congruent sides

∠A = x   .....angle between the 2 congruent sides is labeled x

∠B = ∠C = 65°  .....angles opposite of the congruent sides

To Find:

measure of x = ?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

\angle A+\angle B+\angle C=180\°

Substituting the values we get

x+65 + 65 = 180\n\nx=180-130=50\°

Therefore,

Measure of x is 50°.

The NYC Parks Department is designing a rectangular athletic field for a new park in Brooklyn. The width of the field needs to be 10 feet shorter than the length, and the perimeter of the field needs to be 80 feet. What is the length of the new field?

Answers

Answer:

Length = 25feets

Step-by-step explanation:

Let the length l = x

Width w = x - 10

Perimeter = 80

And Perimeter = 2(l + w)

:- 80 = 2{x + (x - 10)}

80 = 2{x + x - 10}

80 = 2(2x - 10)

80 = 4x - 20

4x = 80 + 20

4x = 100

x = 100/4

x = 25ft
