Answer 1

Answer:

Z=20 Degrees

Step-by-step explanation:

We know that all of the angles of a triangle add up to 180, so:

65+55+ Angle A = 180

Simplify:

120+ Angle A = 180

Subtract 120 from both sides:

Angle A = 60

If you look at the bottom you can see that the 15 turns into 5, meaning it is being divided by 3, so:

60/3=20

Z=20 Degrees

Answer 2

Answer:

Angle E is 60 degrees

Step-by-step explanation:

So z is an angle.

That would be point E.

This triangle was dilatated so we can match it up with the larger one. In a dilation, angle measures do not change. So matching up the points E would be equal to A, which of course it the only one with an angle measure not given.  

All you have to do is add up the two angle measures and subtract that by 180 (total of all angles combined).

So 65+55=120

180-120=60

Angle A is 60

Which makes angle E 60 as well

Hope that helps!

Herb’s mom is a seamstress. She hems shirts, pants and dresses. For each item she hems she gets paid $1.50. If she hems 45 pieces of clothing each day, how much money would she make after working 30 days?

a.) $2,025

b.) $135

c.) $67.50

Answers

Answer: $2025

Step-by-step explanation:

$1.50. x 45= 67.5 items per day. 30  days is 30 x 67.5= $2025

Answer:

a) $2025

Step-by-step explanation:

The equation you would do is

[tex](45(1.50))30[/tex]

by multiplying 45 and 1.50, you get the price of how much money she makes after one day. in order to find 30 days, just take the product of that equation and multiply it by 30 to get $2025

Given:

[tex]\overline{AE}\cong \overline{DE}, \overline{AB}\cong \overline{DC}[/tex]

To prove:

[tex]\Delta ABE\cong \Delta DCE[/tex]

Solution:

In triangle AED,

[tex]\overline{AE}\cong \overline{DE}[/tex]

Two sides of triangle AED are equal, it means triangle AED is an isosceles triangle. The base angles of an isosceles triangle are equal. So,

[tex]\angle A\cong \angle D[/tex]

In triangle ABE and triangle DCE,

[tex]\overline{AE}\cong \overline{DE}[/tex]         (Given)

[tex]\angle A\cong \angle D[/tex]        (Base angles of an isosceles triangle are equal)

[tex]\overline{AB}\cong \overline{DC}[/tex]        (Given)

Two corresponding sides and their included angles are congruent. So, triangles are congruent by SAS postulate of congruence.

[tex]\Delta ABE\cong \Delta DCE[/tex]           (By SAS postulate of congruence)

Hence proved.

Marcus bought a booklet of tickets to use at the amusement park. He used 50% of the tickets on rides, 1/10 of the tickets on video games, and the rest of the tickets in the batting cage. Marcus says he used 38% of the tickets in the batting cage. Do you agree? Complete the explanation.

Answers

Answer:

no

If he used 50% on ticket for rides, the remaining tickets he would have is (100% - 50%) 50%.

He used 1/10 on video games. Converting 1/10 to percentage gives 10%.

The total percentage of tickets used is 60%. He should have 40% to spend on batting cages

A vehicle travels 180 miles in 4 hours. At this rate, how many miles will the vehicle travel in 6 hours?

Answers

Answer:

270 miles

Step-by-step explanation:

Divide 180/4 = 45

45 * 2 = 90

180 + 90 = 270

A vehicle can travel 180 miles in 4 hours, then in 6 hours, the vehicle will travel 270 miles.

What is an arithmetic operation?

The four fundamental operations of arithmetic are addition, subtracting, multiplying, and dividing two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the data given in the question,

Distance travelled by the vehicle = 180 miles

Time is taken to travel 180 miles = 4 hours

Distance travelled in 1 hour = 180/4 = 45 miles

Then,

Distance travelled in 6 hours = 6 × 45 = 270 miles.

A snowboard was $180 but marked as 30% off. There is a state tax of 7.5%. How much would you pay for the snowboard

Answers

Answer:

180(.30)=54, 180-54=126, 126(0.075)=9.45+126=135.45

Step-by-step explanation:

The total is $135.45.

Answer:$135.45

Step-by-step explanation:

180X .30 = 54 dollars off

180-54 =126 so the board on sales costs $126

Adding the tax

126x.075 = 9.45 is the tax due

126+9.45 = 135.45
