Answer The Following Question With Explanation

Answers

Answer 1

Answer:

The answer's D.

Step-by-step explanation:

If 40 questions were put in and only 50% of them were used then only 20 questions were used. If you need 40 more questions and 80% of the qustions were used, then she wrote 50 questions.

Answer 2
Answer:  D) 50

========================================================

Explanation:

There are 60 questions total.

Amita made 40 questions, but only 50% were considered "good" to be used. So that means 0.50*40 = 20 questions were used.

This means 60-20 = 40 questions remain, and this must be the amount of "good" questions that Meena provided.

We're told that 80% of Meena's questions were considered "good". Let x be the total number of questions she provided.

80% of x = (number of "good" questions Meena offered)

0.80x = 40

x = 40/0.80

x = 50

Therefore, Meena wrote up 50 questions.

In the last month, the ratio between Davis's monthly expenditure and his monthly salary was 3 : 7. What percentage of his monthly income did he save last month?

Answers

Answer: 57%

Step-by-step explanation:

Davis's monthly expenditure and his monthly salary was 3 : 7.

This means that for every $7 he received, he spent $3 out of it.

The amount he saved is therefore:

= 7 - 3

= $4

For every $7 received, he saved $4.

Percent = 4/7

= 57%

The sum of the measures of the angles below is 180∘. A triangle is shown. The first angle measures x degrees. The second angle measures two x minus ten degrees. The third angle measures x plus ten degrees. What is the measure of each angle? Write and solve an equation.

Answers

Answer:

First Angle: 45 degrees, Second Angle: 80 degrees, Third Angle 55 degrees

Step-by-step explanation:

180∘= x+ 2x-10∘+ x+10

180∘=4x

x=45∘

2x-10=80∘

x+10=55∘

The measure of the interior angles of the triangle are 45°, 80° and 55°

respectively.

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sum of all the interior angles in a triangle is 180°.

Given, a triangle has interior angles x°, (2x - 10)° and (x + 10)°.

∴ x + (2x - 10) + (x + 10) = 180°.

4x = 180°.

x = 45°.

Answers

Answer:

45

Step-by-step explanation:

Like last question an isosceles has two angles that are the same. The square indicates a right angle so h=90

180-90=90

90/2=45 so G and E equal 45

Because you are given that one angle measures 90 degrees, this is an isosceles right triangle. Therefore, the other two angles must be equal, and  add up to 90 degrees because an isosceles right triangle is exactly half of a square. Also, all angles in a triangle must add up to 180 degrees. Because of these rules, we can completely ignore the expression for angle G and sufficiently say it is 45 degrees.

in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC. calculate area of triangle ABC.​

Answers

Answer:

solution :

in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC.

now ,

in rt angle tirangle ADC,

angleACD=45 degree, angle DAC=45 degree now,

in triangle ABD,

angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)

angle BAD+75+30=180

angle BAD=180-165      therefore,angle BAD=15

angle BAC =15+45=60

Answer:

69°

Step-by-step explanation:

180 - 21 -90 = 69

hope this helps...

Answer: The missing angle is 69°

Step-by-step explanation: When all the angles have their vertex on a straight line, they must add up to 180° They are "supplementary" angles.

The "box" in the corner of an angle is a symbol for "right angle" so that is a way to have a "given" 90°

Knowing that, you can add the "given" 90° + 21° to get 111°

Subtract 111° from 180° to find Angle a:

180 - 111 = 69

Jane has 1 quarter, 3 dimes, and 4 nickels. What percent of dollar does Jane have?

i know the answer is 44% but can someone please explain how i got 44%??

Answers

Answer:

ok so I'm English not a hundred percent sure on your break down of money......so if I'm right in thinking that a nickel = 5 cents, dime = 10cents and a quarter =25cents

you add the amounts together

so 25 + 30 +20 = 75 cents.

there are 100 cents in a dollar so 100/100 X 75=75%

I have no idea how you got to 44%
