Answer:
39
Step-by-step explanation:
Let one angle be x
Then,
Its complementary angle will be =(90-x)
ATQ,
x-(90-x)=12
x-90+x=12
x+x=12+90
2x=102
x=102/2
x=51
Thus,
x=51
(90-x)=(90-51)=39

Answer:
4sqrt(2) + 1
Step-by-step explanation:
Well you know that cos 0 is 1
this means that a+b = 9
cos 60 is 1/2
this means 1/2 a + b = 5
a = 8
b = 1
now plug in for x = 45
cos 45 = sqrt(2)/2
In its first year a manufacturer had a financial loss of 3,000 in its second year the manufacturer had a financial loss of 500 How much greater in dollars was the financial loss in the first year than the financial loss in the second year
Answer:
[tex]D = \$2500[/tex]
Step-by-step explanation:
Given
Represent the financial los s in the first year as F1 and the second year as F2
[tex]F_1 = \$3000[/tex]
[tex]F_2 = \$500[/tex]
Required
How much is greater is F1 than F2
What this question implies is that; the difference between both finan cial losses be calculated;
Represent the difference with D
[tex]D = F_2 - F_1[/tex]
Substitute values for F1 than F2
[tex]D = \$3000 - \$500[/tex]
[tex]D = \$2500[/tex]
Hence, the calculated difference is $2500

A. 8 in.
B. 9 in.
C. 9.5 in.
D. 10 in.
E. None correct
Answer:
b) 9 in
Step-by-step explanation:
To find median arrange the data in ascending order and count the number of data's. if the total number of data is odd number, then (n/2)th term is the median.
If the total number of data is even, then Average of (n/2)th term and (n/2)+1 th term is the median
Ascending order:

The length of a rectangle is 7 inches less than its width. The perimeter of the
rectangle is 54 inches. Find the length and the width of the rectangle. Explain your
reasoning.
Answer:
8 in.
Step-by-step explanation:
Perimeter of a rectangle, P = 2(L + W)
Value of P = 46.
Length is 7 inches less than the width. This translates to L = W - 7
Substitute L = W - 7 into the perimeter equation, you get
46 = 2(W - 7 + W)
46 = 2(2W - 7)
46 = 4W - 14
4W = 60
W = 60 / 4 = 15 in
L = W - 7 = 15 - 7 = 8 in
The width and length of the rectangle in inches are 17 and 10 respectively.
What is perimeter ?Perimeter is the sum of the lengths of all the sides of a given plane figure.
According to the given question the length of a rectangle is 7 inches less than its width.
Assuming the width of the rectangle is x inches.
∴ From the given data length of the rectangle is ( x - 7) inches.
Given perimeter is 54 inches.
We know perimeter of a rectangle is 2( length + breadth).
∴ 2{ x + ( x - 7) } = 54.
2 { 2x - 7 } = 54
4x - 14 = 54
4x = 54 + 14
4x = 68
x = 17.
So, the width of the rectangle is 17 inches and length of the rectangle is (17 - 7) inches which is 10 inches.

Answer:
230 capsules.
Step-by-step explanation:
The following data were obtained from the question:
Taste >>>>>>>>>>> Frequency
Volluto >>>>>>>>>> 12
Livanto >>>>>>>>>> 7
Ristretto >>>>>>>>> 23
Cosi >>>>>>>>>>>> 3
Other >>>>>>>>>>> 5
Next, we shall determine the total frequency.
This is illustrated below:
Total frequency = 12 + 7 + 23 + 3 + 5
Total frequency = 50
Finally, we shall determine the number of Ristretto in 500 capsules.
This can be obtained as follow:
Number of Ristretto = Frequency of Ristretto /total frequency x total capsule
Frequency of Ristretto = 23
Total frequency = 50
Total capsule = 500
Number of Ristretto = 23/50 x 500
Number of Ristretto = 23 x 10
Number of Ristretto = 230.
Therefore, the number of Ristretto in the 500 capsules is 230.

The number of customers to visit a local small businesses 51,200 and has been continuously declining at a rate of 3.8 each year what is the approximate number of customers that visit the business in 14 years
Answer:
=30076 customers
Step-by-step explanation:
Number of customer= 51,200
rate of declination=3.8 %= 0.038
We will use the expresion below in calculating the approximate number of customers that visit the business in 14 years.
A=Pe^(rt)
Where P=initial amt,
r=annual rate of growth or decline,
A=amount after t years.
37800=Pe^.017t
51200=Pe^0.038
P= 51200/e^(0.038*14)
But e^(0.038*14)= 1.7023
P= 51200/1.7023
P=30076
Approximate number of customers that visit the business in 14 years≈30076

Sharika can finish the work in 6 days and Palkey can do the same work in 8 days. They both worked together for for 2 days then Palkey left the work. How many days will Sharika take to finish the remainig work.
Answer:
Sharika needs 2.5 days to finish the remaining work
Step-by-step explanation:
Sharika can do a work in 6 days palkey can do it in 8 days
Then the amount of work sharika can do in 1 day = 1/6
And the amount of work palkey can do in 1 day = 1/8
The amount of work both of them can do together in 1 day = 1/6 + 1/8
= 7/24
The amount of work both of them can do together in 2 day = (2× 7/24)
= 7/12
Since Palkey left the work,the amount of
work remaining for Sharika to do alone = (1 - 7/12 )
= 5/12
The number of days Sharika take to finish the remainig work. = (5/12 ÷ 1/6 )
= 5/2 days
Therefore, Sharika needs 2.5 days to finish the remaining work.
given the relation y=x+2, if the input is 3, what is the output
Answer:
The output is 5
Step-by-step explanation:
y=x+2,
Let x =3
y = 3+2
y = 5
The output is 5
Answer:
5
Step-by-step explanation:
We are given the relation:
y=x+2
The input is also called "x", and the output is also known as "y". We want to find the output, or y, when x is equal to 3.
Therefore, we must substitute 3 in for x and solve.
y= x+2 at x=3
y=3+2
Add 3 and 2.
y=5
If the relation is y=x+2 and the input is 3, then the output is 5.

A 11 L solution that was 25 % vinegar was mixed with a 12 L solution that was 67 % vinegar. Find the new concentration of vinegar.
Answer:
46.91%
Step-by-step explanation:
The first solution contains 11 * 0.25 = 2.75 L of vinegar
The second solution contains 12 * 0.67 = 8.04 L of vinegar
When mixed together, that adds up to 8.04 + 2.75 = 10.79 L of vinegar
The total volume of the combined solutions is 11 + 12 = 23 L of solution
So the new concentration is 10.79/23 ≈ 0.4691 ≈ 46.91%

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled.
Answer:
Value of miles traveled (m) = 13 mile
Step-by-step explanation:
Given:
Equation
3.00 + 0.50 m = 9.50
Find:
Value of miles traveled (m)
Computation:
3.00 + 0.50 m = 9.50
0.50 m = 9.50 - 3.00
0.50 m = 6.50
m = 6.50 / 0.50
m = 13
Value of miles traveled (m) = 13 mile
Answer:
The question is not complete, below is the complete question:
A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled.
Which statement shows the meaning of the driver's equation? Check all that apply.
a.) Three dollars added to $0.50 is the same as $9.50.
b.) Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.
c.) Three dollars more than the quotient of $0.50 and the number of miles is nine dollars and fifty cents.
d.) The product of the number of miles and the sum of $3 and $0.50 is equal to $9.50.
e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
Answers
The correct answers are:
b
e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
Step-by-step explanation:
The formula written by the driver is: 3.00 + 0.50 m = 9.50
where m = number of miles travelled
This means that when the product of 0.50 and the number of miles travelled 'm' is added to $3, the result is 9.50
And this is the same explanation as the following options:
a.) Three dollars($3) plus $0.50 times the number of miles is equal to nine dollars and fifty cents($9.50).
e.) e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents;
note that 50 cents is the same as $0.50
