Answer:
800
Step-by-step explanation:
52 weeks in a year then multiply 15.40
Answer:
$803
Step-by-step explanation:
cost of electricity for 1 week = 15.40
⇒ cost of electricity for 1 day = 15.40 ÷ 7 = 2.20
⇒ cost of electricity for 365 days = 2.20 x 365 = 803

What is the equation of the line that passes through the point (−8,−7) and has a slope of 1?
Answer:
y = x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 1 , then
y = x + c ← is the partial equation
To find c substitute (- 8, - 7 ) into the partial equation
- 7 = - 8 + c ⇒ c = - 7 + 8 = 1
y = x + 1 ← equation of line

The perimeter is increased by a factor of 21. The perimeter is increased by a factor of 25. The perimeter is increased by a factor of 92.
The perimeter of the rectangle is got increased by a factor of 2. The correct option is A.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In rectangle opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at mid-point.
Given
A rectangle has a width of 12.5 m and a length of 105 m.
We know the perimeter of the rectangle is given by
Perimeter = 2 (Lenght + Width)
Let x be the length and y be the width. Then
Perimeter = 2 (x + y)
If the dimensions are multiplied by 2. Then the effect on the perimeter will be
Perimeter = 2 (2x + 2y)
Perimeter = 2 [2 (x + y)]
The perimeter is increased by a factor of 2.
Thus, option A is correct.

harmaine spent a total of $20 at the grocery store. Of this amount, $9 she spent on fruit. What percentage of the total did she spend on fruit?
Answer:
45%
Step-by-step explanation:
First, let's set up a fraction of how much money she spent for fruit out of the total amount of money she spent.
[tex]\frac{9}{20}[/tex]
For a percentage, we need a fraction out of 100. To do this, we can multiply the fraction by 5/5 (5*20=100). Notice we can only do this since 5/5 is equivalent to 1, so you are technically multiplying the fraction by 1.
[tex]\frac{9}{20}*\frac{5}{5}=\frac{45}{100}[/tex]
A percentage is just the numerator of a number over 100 therefore it is equal to...

Fred is an old man he lived 1\8 of his life as a boy, 1\12 as a youth, 1\2 as a man and 28 years in his old age. How old is Fred now
1. Observe problem
1-(1/8+1/12+1/2)
Make all common denominator
The Least common multiple of 8,12, and 2 is 24
1-((3+2+12)/24)=
1-17/24=
7/24
Therefore, 28 years make up 7/24 of his life.
Simplifying, he grows 4 years for every 1/24 of his life
4 times 24 is 96, so
Fred is 96 currently(that's pretty old)

Juan's bag of apples weighed 31/7 pounds. Ari's bag of oranges weighed 19/3 pounds . Using compatible fractions estimate how muchh heavier Ari's bag is compared to Juan's bag?
Rewrite the fractions to have a common denominator:
Juan: 31/7 x 3 = 93/21
Ari: 19/3 x 7 = 133/21
now you can subtract:
133/21 - 93/21 = 40/21 pounds = 1 and 19/21 pounds heavier

Find the slope of the line that passes through G(−3, 2) and H(7, 2).
PLEASE I DONT HAVE TIME I BEG U
The solution is, the slope of the line that passes through G(−3, 2) and
H(7, 2) is 0.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
given that,
G(−3, 2) and H(7, 2).
now, we have to find, the slope of the line that passes through G(−3, 2) and H(7, 2).
now, we know that,
Slope = (y2-y1) / (x2-x1)
here,
G(-3,2) = (x1,y1)
H(7,2) = (x2,y2)
Substitute these values to find the slope.
Slope = (2-2)/(7-(-3))
= 0/10
= 0
Hence, The solution is, the slope of the line that passes through G(−3, 2) and H(7, 2) is 0.

A vessel sails 41 miles S 45 E. How far south has it sailed?
119 miles
61 miles
29 miles
Answer:
[C] 29 Miles
Step-by-step explanation:
Given that the vessel sails 41 miles S 45° E.
We need to determine the how far south the vessel has sailed.
Let us use the Pythagorean theorem to find the distance of the vessel has sailed.
Thus, we have,
[tex]Cos 0= \frac{adj}{hyp}[/tex]
Substituting [tex]0 = 45[/tex]° , [tex]adj = x[/tex], and [tex]hyp = 41[/tex]
Hence, we get,
[tex]cos[/tex] [tex]45 = \frac{x}{41}[/tex]
Simplifying, we have,
[tex]0.71 = \frac{x}{41}[/tex]
Multiplying both sides by 41, we have,
[tex]29.11 = x[/tex]
Rounding off to the nearest integer, we have,
[tex]29 = x[/tex]
Thus, the vessel has sailed 29 miles South.
Therefore, Option C is the correct answer.
