Ms. Mor ris has 35 tests to grade this weekend. Mrs. Cook has 80% more tests than that to grade this weekend. How many tests does Mrs. Cook have to grade?
Answer:
Mrs. Cook has to grade 63 tests.
Step-by-step explanation:
In order to find the answer, first you have to calculate 80% of the number of tests Ms. Morris has:
35*80%= 28
Then, you have to add the number that represents 80% to the number of tests Ms. Morris has to grade:
35+28=63
According to this, the answer is that Mrs. Cook has to grade 63 tests.

Yesterday, Ian walked 2/3 of a mile. Today, he walked 1/5 of a mile. How far did he walk altogether?
Answer:
1.4km
Step-by-step explanation:
2/3 + 1/5
Find the LCM of the denominators
(5x2)+(3x1)/15
Clear brackets:
5x2=10
3×1=3
Therefore, we have
10+3/15=13/15
In total, he has walked 13/15 of a mile
1 mile is 1.609344 km
Therfore, he walked 13/15×1.609344 km=1.4km approximately.
OR
2/3 of 1mile is 2/3×1.609344 km
=1.07km
1/5 of 1 mile the next day is 1/5×1.609344 km
=0.32km
Total distance 1.07+0.32=1.39 approximately 1.4km
Ian walked 13/15 miles altogether.
What is fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given:
Yesterday, Ian walked 2/3 of a mile.
Today, he walked 1/5 of a mile.
To find the number of miles, he walks altogether:
The sum of both the fractions,
2/3 + 1/5
= (2 x 5 + 3 x 1) / 15
= (10+3) / 15
= 13/15
Therefore, he walks 13/15 miles.

What are the values of x and y that make the equations true?
Equation A
(x + yi) + (4 – 7i) = 3 – 4i
Equation B (x + yi) - (-6 + 14i) = 18 + 2i
In equation A, x= ____ and y= ____
In equation B, x= ____ and y= ____
Answer:
In equation A, x= -1 and y= 3
In equation B, x= 12 and y= 16
Step-by-step explanation:
Given the expression
(x + yi) + (4 – 7i) = 3 – 4i
We are to find the value of x and y
Expand the equation;
(x + yi) + (4 – 7i) = 3 – 4i
x + yi + 4 – 7i = 3 – 4i
x+4+yi-7i = 3 - 4i
x+4 + (y-7)i = 3-4i
Equate the real part
x+4 = 3
x = 3-4
x = -1
Equate the imaginary part;
y - 7 = -4
y = -4 + 7
y = 3
In equation A, x= -1 and y= 3
For equation B:
(x + yi) - (-6 + 14i) = 18 + 2i
x+yi+6-14i = 18+2i
x+6+(y-14)i = 18+2i
x+6 = 18
x = 18-6
x = 12
Equate the imaginary part;
y - 14 = 2
y = 2 + 14
y = 16
Hence In equation B, x=12 and y= 16
Answer:
In equation A, x= -1 and y= 3 In equation B, x= 12 and y= 16
Step-by-step explanation:
Given the expression
(x + yi) + (4 – 7i) = 3 – 4i
We are to find the value of x and y
Expand the equation;
(x + yi) + (4 – 7i) = 3 – 4i
x + yi + 4 – 7i = 3 – 4i
x+4+yi-7i = 3 - 4i
x+4 + (y-7)i = 3-4i
Equate the real part
x+4 = 3
x = 3-4
x = -1
Equate the imaginary part;
y - 7 = -4
y = -4 + 7
y = 3
In equation A, x= -1 and y= 3
For equation B:
(x + yi) - (-6 + 14i) = 18 + 2i
x+yi+6-14i = 18+2i
x+6+(y-14)i = 18+2i
x+6 = 18
x = 18-6
x = 12
Equate the imaginary part;
y - 14 = 2
y = 2 + 14
y = 16
Hence In equation B, x=12 and y= 16

What is 332 to the power of-6 times 332 to the power of 3
When multiplying the same number is raised to different exponents add the exponents together:
332^-6 x 332^3 = 332^(-6 +3) = 332^-3
Then when a number is raised to a negative exponent, change the exponent to a positive value and make the number a fraction, as the denominator, with 1 as the numerator:
332^-3 = 1/332^3
1/332^3 = 1/36594368

Answer:
One serving of Grapefruit juice has 41 more mg of Vitamin C than one serving of Tomato juice
Step-by-step explanation:
This question is asking for a comparison of the amount of Vitamin C is Grapefruit juice, 86 mg, and Tomato juice, 45 mg. Because the question is worded so that whichever juice has the most Vitamin C is put first, Grapefruit juice must be put first. The next part is asking for the difference in the amount of Vitamin C between Grapefruit and Tomato juice, which can be found by simplifying an expression such as 86-45. This leaves the answer being 41, which will be put in the second box. Finally, the third box is asking for the juice with the lowest amount of Vitamin C, which is the tomato juice.

Rick is buying $115 tennis racket from a sporting good store. If the racket is on sale for 35% off in sales tax is 8% how much will he pay in total
Answer:
$80.73
Step-by-step explanation:
First, find 35% of 115.
35% as a decimal is 0.35 (35/100)
0.35 x 115 = 40.25
Now, subtract 40.25 from 115.
115 - 40.25 = 74.75
Now, to find the sales tax, find 8% of 74.75.
8% as a decimal is 0.08 (8/100)
0.08 x 74.75 = 5.98
Now, subtract add 5.98 to 74.75
5.98 + 74.75 = 80.73
