In Rectangle ABCD, m

Answers

Answer 1

Answer:

m∠ACD = 24°

Step-by-step explanation:

Measure of the interior angles of a polygon = [tex]\frac{(n - 2)\times 180}{n}[/tex]

Therefore, measure of the interior angles of a rectangle = [tex]\frac{(4 - 2)\times 180}{4}[/tex]

= [tex]\frac{360}{4}[/tex]

= 90°

m∠BCD = 90°

Since, m∠BCD = m∠BCA + m∠ACD

90° = 66° + m∠ACD

m∠ACD = 90° - 66°

= 24°

Therefore, measure of angles ACD is 24°.

What is the quadrilateral?

The definition of a quadrilateral is a planar form with four sides, four vertices, and four angles. Concave and convex are the two primary kinds.

If all the sides of the quadrilateral are identical, then the quadrilateral will be a square.

In the square, each angle will be a right angle. And the diagonals of the square intersect at a right angle.

Thus, the measure of the angle ∠GQE will be 90°. Then the correct option is C.

The diameter of a circle is 6 yards. What is the circle's circumference?

Answers

Step-by-step explanation:

formula for circumference of the cricle = 2πr

π = 3.14

r= radius of the circle

diameter of the circle = 6

radius of the circle = d/2 = 6/2= 3

circumference = 2πr

= 2×3.14×3

= 18.84

circumference of the given circle is 18.84 yards.

You need to decide whether to hire three landscapers or hire just two but buy a faster mower; both options will deliver the same revenue. If landscapers cost you $18 an hour and work 2000 hours a year, and the new mower will cost $8,000, which option will be cheaper for you over the next three years?

Answers

Answer:

I think buying a new mower will be a much more financial sound decision because it can last 3 years, however, if you hire landscapers it will cost significantly much more money than buying a new mower.

Step-by-step explanation:

Reason for this is that:

$18×2000 hours= $36,000 each year

For three years: $36,000×3=$108,000

which is more than $8,000

Hence, buying a new mower would be the better solution.

The points ( 2,4) and (5,y) lie on the same line. If the slope of the line is -IA, what is the value of y

Answers

Answer:

y = 1

Step-by-step explanation:

Correct question

The points ( 2,4) and (5,y) lie on the same line. If the slope of the line is --1, what is the value of y

The formula for calculating slope of a line is expressed as;

m = y2-y1/x2-x1

Substitute the given point

y - 4/5-2 = -1

y-4/3 = -1

y-4 = -3

y = -3+4

y = 1

Hence the value of y is 1

The ratio of money in Terry's bank account to Faye's bank account was 3:5.
Terry then put £220 in his account and Faye withdrew £300 from her account.
They now had the same amount in their accounts.
How much did Terry initially have?

Answers

Answer:

They initially had £1250 altogether.

Explanation:

Given : The ratio of money in Terry's bank account to Faye's bank account was 3:7.

Let the money in terry's bank account be 3x and the money in Faye's account be 7x.

if Terry put £220 in his account and Faye withdrew £300 from her account.

Money in Terry's account = 3x+200

Money in Faye's account = 7x -300

They now had the same amount in their accounts.

Now Initially ,

Amount in Terry's account = 3x= 3(125) = £ 375

Amount in Faye's account = 7x =7 (125)= £ 875

Combined amount = £ 375 + £ 875 = £1250

Hence, they initially had £1250 altogether.

If the product of two rational numbers is (-9/16) and one of them is (-4/15) find the other number.

Answers

Given:

The product of two numbers is (-9/16).One of the numbers is (-4/15)

To find: The other number.

Answer:

Let's assume the unknown number to be 'x'.

(-4/15) × x = (-9/16)

× = (-9/16) ÷ (-4/15)

When we divide a fraction by another fraction, the divisor will be taken in its reciprocal form.

x = (-9/16) × (-15/4)

x = 135/64

Therefore, the other number is 135/64.

Abe has some nickels and some pennies. If the pennies were nickels and the nickels were pennies, he would have 80 cents less than he has now. The difference between the number of nickels and the number of pennies that he has

A) Is 12

B) Is 20

C) Is 24

D) Is 28

E) Cannot be Determined

Answers

Answer:

B) Is 20

Step-by-step explanation:

Let X represent the number of pennies.

Let Y represent the number of nickels.

We know that X + 5Y = (Y + 5X) + 80.

4Y = 4X + 80

Y = X + 20

Hence, the difference between the number of pennies and the number of nickels is 20.
