slope , m = 3 .y -intercept , b =7

Answers

Answer:

The slope is 3 and the y-intercept is 7. The equation of the line is 3y - 7.

Step-by-step explanation:

The equation of the line works such that y = mx + b where m is the slope and b is the y-intercept. Thus,

slope = m

         = 3

y-intercept  = b

                   = 7

In ABC, the interior angle at A is 51° and the exterior angle at B is 119º. The interior angle at C measures
A 51°
B 68°
C 90°
D 39°

Answers

Answer:

68 degrees

Step-by-step explanation:

To get the interior angle, we use an important triangle principle

The principle is that the sum of the opposite interior angles equal the exterior angle

Let the second interior angle be x

x + 51 = 119

x = 119-51

x = 68

Answers

Answer:

Total area ≈ 0.082 ​

Step-by-step explanation:

Round answers to three decimal places.

Area of 1st rectangle = 0.032

Area of 2nd rectangle =25 x 0.000863

= 0.022

Area of 3rd rectangle = 0.014

Area of 4th rectangle = 0.008

Area of 5th rectangle = 0.004

Area of 6th rectangle = 0.002

Total area = 0.082 ​

Rounding up to 3 decimal places: this means 3 numbers after the decimal point

Area of 1st rectangle ≈ 0.032

Area of 2nd rectangle ≈ 0.022

Area of 3rd rectangle ≈ 0.014

Area of 4th rectangle ≈ 0.008

Area of 5th rectangle ≈ 0.004

In fixed deposit, a bank gives 10% interest compounded annually for senior citizens. How many complete years will it take for a sum of money to be more than double.

Answers

Answer: 8 years

Step-by-step explanation:

You can find this out use the Rule of 72. By dividing 72 by the fixed interest rate, you can estimate the amount of time it will take for an investment to double in size:

= 72/10

= 7.2 years

= 8 complete years

Example:

Assume they invested $1,000. Interest rate is 10%.

Amount after 8 years will be:

= 1,000 * (1 + 10%)⁸

=$2,143.59

Investment is now more than double.

11. The price of a bottle of water at a store decreases from $1.65 to $1.40. Rounded to the nearest
tenth of a percent, what is the percent decrease in the price of the bottle of water?
A. 15.2%
B. 17.9%
C. 45.9%
D. 54.1%

Answers

Answer:

A. 15.2%

Step-by-step explanation:

Subtract the new price from the old one to find the dollar amount that the water bottle price was reduced.

[tex]1.65-1.40=0.25[/tex]

The price was reduced by 25 cents, but we need to find the percentage. To do that, we divide the price reduction by the original price.

[tex]0.25/1.65=0.152[/tex]

And then move the decimal place over two spots (multiply by 100)

15.2

Percent decrease in the price of the bottle of water is 15.2% (Approx.)

Given that;

Older price of bottle = $1.65

New price of bottle = $1.40

Find:

Percent decrease in the price of the bottle of water

Computation:

Percent decrease in the price of the bottle of water = [(1.65 - 1.40) / 1.65]100

Percent decrease in the price of the bottle of water = [(0.25) / 1.65]100

Percent decrease in the price of the bottle of water = [(0.25) / 1.65]100

Percent decrease in the price of the bottle of water = 15.2% (Approx.)

Malcolm is filling bags with rice. He starts with a 5 1/4 pound container of rice and fills each bag with 5/8 pound of rice. How many bags of rice can malcolm fill??

Answers

Answer:

part 1: Divide 5 1/4 pound by 5/8 pound

part 2: 8 bags

part 3: 2/5 of another bag

Step-by-step explanation:

total number of bags that can be filled equals total rice divided by the amount of rice per bag

=5 1/4 divided by 5/8

=(21/4)/(5/8)                   turn the mixed number into improper fraction

=(42/8)(5/8)                      common denominator

=42/5

=8.4 bags, but can only fully fill 8 bags

2/8 pounds of rice are left over after filling 8 bags, and 2/8 pounds is equal to

2/5 of another bag

(2/8)/(5/8)

The parallelogram shown below has an area of 21 units?.

Find the missing base.
b=
units

Answers

Answer:

The missing base b is 3 units

Step-by-step explanation:

The parallelogram has two different bases, b1 and b2Each base has a height perpendicular to it from the base parallel to ith1 is the height of b1 and h2 is the height of b2The formula of the area of the parallelogram is A = b1 × h1 = b2 × h2

Let us solve the problem

In the given figure

The given figure is a parallelogram

∵ The line of length 7 is perpendicular to the base that parallels to base b

∵ The base b has a height of 7 units

→ By using the formula of the area above

∵ A = b1 × h1

b1 = b and h1 = 7 units

∵ The parallelogram has an area of 21 square units

A = 21

→ Substitute the value of A and h in the rule of the area

21 = b × 7

∴ 21 = 7b

→ Divide both sides by 7

3 = b

The missing base b is 3 units

What is the measure of the third angle

Answers

58

a right triangle is 90 degrees so you subtract 32 from 90 to find the remainder

Answer:

The third angle is 58 degrees

Step-by-step explanation:

In a triangle all three angles add up to 180 degrees. If you know two sides, add them up then subtract the sum from 180. This will leave you with the last angle measurement.

In a right triangle we always know there is one angle that has a measure of 90 degrees. So now we know two angles 90 and 32.

90 + 32 = 122

180 - 122 = 58
