Answer:

0.87

Step-by-step explanation:

Out of a total number of 100 questions, Daniel is said to have answered 87.

We first express this as a fraction.

Total number of questions he answered divided by total number of quiz questions

= 87/100

As a decimal, 87 divided by 100 = 0.87.

You can easily get this by using the calculator.

Thank you!

Step-by-step explanation:

Answer:

x = 0 and y = 4.

Step-by-step explanation:

The given equations are :

4x+2y=8 ...(1)

x+y=4 ...(2)

Multiply equation (2) by 2.

2x+2y=8 ...(3)

Subtract equation (3) from (1).

4x+2y-(2x+2y)=8-8

4x+2y-2x-2y=0

2x = 0

x = 0

Put the value of x in equation (2).

0+y=4

y = 4

So, the value of x and y are 0 and 4.

Answer:

See explanation

Step-by-step explanation:

∠POR is congruent to ∠VOE because they are vertical angles

∠PRV is congruent to ∠RVE because alternate interior angles are congruent when the lines are parallel.

VO is congruent to OR which is given

Therefore, ΔPRO is congruent to ΔEVO by the angle-side-angle theorem

So, PR is congruent to VE because corresponding parts of congruent triangles are congruent

Answer:

  commutative property

Step-by-step explanation:

The commutative property of multiplication lets you swap the order of the operands (7*3) and 8 to make them have the order 8 and (7*3).

Answer:

5.3

Step-by-step explanation:

a² + b² =² c²               the Pythagorean theorem

RQ² + RS² = QS²            Solve RS

6² + RS² = 8²

RS² = 64 -36

RS² = 28

RS = √28                  28 is slightly > 25   and since  √25 =5

RS = 5.3                    actually 5.2915  to a few more significant digits

Answer:

240 minutes or 4 hours

Step-by-step explanation:

So if it takes Erica 80 minutes to analyze the company's monthly credit card statements, she will get 30/80 of it done in 30 minutes.

If it takes Alexa 2 hours to analyze the company's monthly credit card statements, she will get 30/120 of it done in 30 minutes.

Add 15 to each of the fractions because they analyze the company's monthly credit card statements with Mack for 15 more minutes.

So you have 45/80 and 45/120.

Now add both fractions by finding the lowest common denominator which is 240.

135/240 + 90/240 = 225/240

So Mack did the remaining 15/240.

Now to find how long it would take him to analyze the company's monthly credit card statements by himself divide 240 by 15 which is 16.

Then multiply

15 x 16 = 240

so it would take him 240 minutes or 2 hours.

Answer:

15 (3rd option)

Step-by-step explanation:

Circumference formula=2 x pi x r(radius)

So, 30 pi = 2 pi r

Next, isolate the r(radius)

30 pi / 2 pi = r

The 2 pi's cancel out and leaves 30/2

r=15

Answer:

SA = r (PI)   + r (PI) 2

Step-by-step explanation:

The surface area of the solid figure would be; SA = πrl + πr²

The total surface area of a cone is given by:

The Surface area of the cone =[tex]\pi r(r+\sqrt{h^2+r^2} )[/tex]

where r is the radius of the cone, h is the height of the cone, l is the length of the cone

Since it is known that Right circular cone is the cone in which the line joining peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.

Length = [tex]\sqrt{h^2+r^2}[/tex]

Therefore, we can conclude that;

The total surface area of the cone is given by the following formula;

SA = πrl + πr²

Answer:

63

Step-by-step explanation:

use tangent formula

[tex] \tan(40) = \frac{h}{75} [/tex]

Answer:

h ≈ 62.9 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{75}[/tex] ( multiply both sides by 75 )

75 × tan40° = h , then

h ≈ 62.9 ft ( to 1 dec. place )
