A factor delivered 284 boxes of books to stores. There are 20 books in each box. How many books did the factor deliver?
Answer:
284*20
Step-by-step explanation:
since there are 284 boxes of each 20 books, 1box = 20 books then 284 boxes = (284*20) books
If factor delivered 284 boxes of books to stores and 20 books in each box then the total number of books deliver by factor are 5680.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that a factor delivered 284 boxes of books to stores.
There are 20 books in each box.
We have to find the number of books the factor deliver
To find this we have to multiply the number of boxes with the number of books in a box
Number of books deliver = 284×20
Two hundred eighty four times of twenty
Number of books deliver =5680
Hence, if factor delivered 284 boxes of books to stores and 20 books in each box then the total number of books deliver by factor are 5680.

find the area of the circle.
diameter=8 inches
Answer:
Area = 32 π in^2
Step-by-step explanation:
Area of the Circle : Area = 2 *π * r^2
diameter = 2 *radius
8 inches = 2 * radius
radius = 8 in/2 = 4 in
radius = 4 in
Area = 2 *π * r^2
Area = 2 *π * (4 in)^2
Area = 2 *π * 16 in^2
Area = 32 π in^2

Does the graph shows a proportional relationship
Answer:
no
Step-by-step explanation:
a proportional relationship when graphed always is a straight line that goes through the origin (0,0)
The graph shown, shows a straight line but the line doesn't go through the origin therefore the graph does not show a proportional relationship.
Note that the origin is where the x and y axis cross , or the bottom right corner of the graph in this case

The function b(t)= 4.891(1.331)^t is an exponential function
The percentage of executives in 2000 is 15.35The percentage of executives in 2001 is 20.43The percentage of executives in 2000The function is given as:
b(t)= 4.891(1.331)^t.
2000 is 4 years from 1996.
This means that t = 4
So, we have:
b(4)= 4.891(1.331)^4
Evaluate
b(4)= 15.35
So, the percentage of executives in 2000 is 15.35
The percentage of executives in 20012001 is 5 years from 1996.
This means that t = 5

given g(x)= cubed root of x-5,on what interval is the function negative?
a. (-infinity,-5)
b. (-infinity,5)
c. (-5,infinity)
d. (5,infinity)
The cube root function is negative on the interval (-∞, 5), so the correct option is b.
When the function is negative?
Here we have the cube root function:
g(x) = ∛(x - 5)
This is a cube root, and it is negative when the argument is negative. So the function will be negative for the values of x such that:
x - 5 < 0
x < 5
So, we can say that on the interval: (-∞, 5) the function g(x) is negative. Then the correct option is b.

One angle of an isosceles triangle measures 74°. What measure is possible for the other two angles?
Answer:
Either 74° and 32°
or 53° and 53°
Step-by-step explanation:
An isosceles triangle has at least two congruent angles.
There are two possibilities in this problem.
1)
The 74° angle is one of the two congruent angles.
Then, one other angle measures also 74°.
The third angle measures 180° - 74° - 74° = 32°
2)
The 74° is not one of the two congruent angles.
Then the other two angles are congruent.
180° - 74° = 106°
The sum of the measures of the two congruent angles is 106°, so each of the two congruent angles measures 53°.
Answer:
Either 74° and 32°
or 53° and 53°
Max went to a shopping mall with $35 in his wallet. He spent two fifths of the money he had in his wallet at the bookstore. How much money, in dollars, did he have left?
$21
$26
$10
$13
Answer:
$21
Step-by-step explanation:
1) Find the amount spent.
"Two fifths" = 2/5
So, he spent 2/5 of 35.
= 2 x 35 / 5
= 70 / 5
= 14
2) Subtract 14 from 35, since 35 is the total amount of money he had.
= 35 - 14
= 21
Answer:
$21
Step-by-step explanation:
Given that:
Max went to a shopping mall with $35 in his wallet.
He spent two fifths of the money he had in his wallet at the bookstore.
To Find:
How much money, in dollars, did he have left?
Solution:
Let the left money that max have = x
Base on the given:
$35-(2/5)×$35=x
⇒ $35-($2×7)=x
⇒ $35-$14=x
⇒ x=$21
Hence, max has $21 left.

Which of the following number CANNOT represent the probability of an event?
A. 0.888
B. 0
C. 4.2
D. 0.39
Answer:
c
4.2 would mean a 420% chance of something happening which doesnt make sense
The number 4.2 cannot represent the probability of an event because it is greater than one.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The probability of an event must be less than or equal to one.
So 0.888 can represent the probability of an event because it is a non-negative number that is less than or equal to one.
0, cannot represent the probability of an event because it is a non-negative number but it is not less than or equal to one. This number represents an impossible event.
4.2, cannot represent the probability of an event because is greater than one which means it represents an event that is certain to occur, which is not a probability.
0.39, can represent the probability of an event because it is a non-negative number that is less than or equal to one.
Therefore, the number 4.2 cannot represent the probability of an event because it is greater than one.

work out size of angle x
Answer:
x = 105 degrees.
Step-by-step explanation:
The small polygon is a regular hexagon so each internal angle = 120 degrees while the large polygon is a regular octagon with internal angle =
135 degrees.
So angle x = 360 - ( 120 + 135)
= 360 - 255
= 105 degrees.
Note we use the fomula T = 180( n - 2) to find total internal angles in an n sided polygon. So for hexagon T = 180(6-2) = 180*4 = 720 so each internal angle in a regular hexagon = 720/6 = 120 degrees.

Last year a company spent a total of £2400 on advertising. This year they spent £2796 What was the percentage increase in their spending on advertising?
Answer:
16.5%
Step-by-step explanation:
[tex] \frac{396}{2400 } \times 100[/tex]The percentage increase in their spending on advertising will be 16.5%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Last year an organization spent a sum of £2400 on publicizing. This year they burned through £2796.
Then the percentage increase in their spending on advertising will be given as,
P = [(2796 - 2400) / (2400)] x 100
P = (396 / 2400) x 100
P = 0.165 x 100
P = 16.5%
The percentage increase in their spending on advertising will be 16.5%.
