Step-by-step explanation:
If there are 4 fewer blue pens in a box than black pens, and there are 15 black pens in each box, then that means there are 11 blue pens in each box.
So then, how many blue pens are in 3 boxes? There are 33 blue pens in 3 boxes, you can find this out by multiplying, 11 by 3.
the numerical answer is:
11 x 3 = 33
or, 3 x ( 15 - 4)

Value of x ?
X/2=8.5
Answer:
x=17
Step-by-step explanation:
to find x use this
[tex]\frac{x}{2} =8.5[/tex]
x=8.5*2=17
Answer:
x=17
Step-by-step explanation:
To solve the equation, we want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
x/2=8.5
x is being divided by 2. The opposite of division is multiplication. Multiply both sides by 2.
2*x/2=8.5*2
x=8.5*2
x=17
To check the solution, substitute 17 in for x in the original equation.
Original equation: x/2=8.5
Substitute 17 in for x: 17/2=8.5
17/2=8.5
8.5=8.5
This is true, so we know that x is equal to 17.

An exterior angle of a regular polygon is 72°.
(i) what is the size of each interior angle of the polygon?
(ii) Find the number of sides of the polygon.
Answer:
Exterior angle = 72⁰
As polygon is regular , each interior angle = 180⁰ - 72⁰ = 108⁰
Number of sides :
As the sum of exterior angles is 360⁰ :
n × 72⁰ = 360⁰

Bob Tina and Hadley went running. Bob ran for 3/8 hour, Tina ran for 3 4/9 hours, and Hadley ran for 4 19/29 hours. Which running times can be written as improper fractions
Answer: 3 4/9 and 4 19/29
Step-by-step explanation: Mixed fractions can be converted into improper fractions. Example: 3 1/2=
3×2+1= 7/2
So, 3 4/9= 3×9+4= 31/9
4 19/29= 4×29+19= 135/29

An improper fraction is one in which the numerator is bigger than the denominator, which means the value of the fraction is more than ' 1 ' .
Bob petered out after only 3/8 of an hour. This number is less than ' 1 ', so if it's left in the form of hours, it can't be an improper fraction. If Bob wants his effort to look more impressive, he might try to describe his performance as 22.5 minutes. THAT number could be written as an improper fraction, (45/2 minutes), but somebody would be sure to notice his trick, and they would laugh at him.
Tina and Hadley both ran longer than 1 hour, so both of them could write their times directly as improper fractions, without any deceptive monkey business.
Tina . . . 3-4/9 hours . . . 31/9 hours
Hadley . . . 4-19/29 hours . . . 135/29 hours

You have to solve for y
Answer:
[tex]y = 2 \sqrt{5} [/tex]
Step-by-step explanation:
[tex]y^{2} = ef = 5 \times 4 = 20[/tex]
[tex]y^{2} = 20[/tex]
[tex] \sqrt{y} = \sqrt{20} [/tex]
[tex]y = 2 \sqrt{5} [/tex]
Which two transformations can be used to
obtain the graph of y = 3(x - 5)2 from the
graph of y = x2?
F. A vertical compression and a translation
5 units left.
G. A vertical stretch and a translation
5 units left.
H. A vertical compression and a translation
5 units right.
J. A vertical stretch and a translation
5 units right.
We have been given that that function [tex]y=3(x-5)^2[/tex] is obtained from the graph of [tex]y=x^2[/tex]. We are asked to find the two transformations that can be used to obtain the transformed function.
We will use transformation rules to solve our given problem.
[tex]f(x-a)\Rightarrow\text{Graph shifted to the right by a units}[/tex], where a is any positive number.
We can see that the value of a is 5 for our given function, therefore, graph is shifted to right by 5 units.
Now we will use scaling rules.
[tex]f(x)\Rightarrow a\cdot f(x)[/tex]
If [tex]a>1[/tex], then function is stretched vertically by a factor of 'a'.
If [tex]a<1[/tex], then function is compressed vertically by a factor of 'a'.
We can see that value of a is 3. Since 3 is greater than, so function will be stretched vertically by a factor of 3.
Therefore, the function can be obtained by a vertical stretch and translation of 5 units to right and option J is the correct choice.

Answer:
35 degrees
Step-by-step explanation:
a triangle has 180 degrees so 70 + 75 + x = 180
solve for it and you get 35 degrees.
Answer:
x = 35
Step-by-step explanation:
We know that the sum of all the angles inside a triangle is 180°. We can solve for x by setting up the simple equation x + 70° + 75° = 180°
You would then use subtraction to get x by itself by subtracting 70° and 75° from the left and right side of the equation.
This would leave you with the answer, x = 35°
A science teacher collects 18 pints of lake water for a lab she is teaching. The lab requires each student to use 4 fluid ounces of lake water. If 52 students are participating, how many pints of lake water will the teacher have left over?
Answer:
The teacher will have 5 pints left.
Step-by-step explanation:
One pint has 16 fluid ounces, therefore if the teacher got 18 pints he has a total of:
lake water = 18*16 = 288 fluid ounces
If each student use 4 fluid ounces, and there are 52 students the class will use:
used = 52*4 = 208 fluid ounces
And the remainder will be:
remainder = 288 - 208 = 80 fluid ounces
remainder = 80/16 = 5 pints
The teacher will have 5 pints left.
To qualify for the postcard rate for postage, a postcard must be less than 4 1/2 inches high. Elayne has a postcard that is 4 7/8 inches high. How much is her postcard over the height limit?
Answer:
3/8 inches
Step-by-step explanation:
The postcard must be less than 4 1/2 inches high.
Elayne's postcard is 4 7/8 inches high.
We need to subtract the limit from the height of her postcard to know how high it is above the limit:
4 7/8 - 4 1/2 = 3/8
Her postcard is higher than the limit by 3/8 inches.
The answer is 3/4 or 1 1/2 inches.

The product of two rational numbers is (-28/81). If one of them is (-2/3), the find the other.
Answer:
The other rational number is [tex]\dfrac{14}{27}[/tex].
Step-by-step explanation:
First rational number is [tex]\dfrac{-2}{3}[/tex]
Let other rational number is [tex]\dfrac{x}{y}[/tex]
The product of two rational numbers is [tex]\dfrac{-28}{81}[/tex]

Step-by-step explanation:
The low temperatures for the week in Carrollton, in degrees Fahrenheit (°F), were 17, 41, 11, 14, 11, 13, and 15. What is the mean of the temperatures without the outlier?
Answer:
The mean of the temperatures is 13.5 without the outlier.
Step-by-step explanation:
To find the mean, you add all of the numbers in your data set and divide that by how many numbers you added.
Before we do this, we must first identify the outlier and remove it from our calculations since it is asking us to find the mean without it. 41 is the outlier because it is a considerably larger number than the other numbers in the data set.
Equations: 11 + 11 + 13 + 14 + 15 + 17 = 81
81 ÷ 6 = 13.5

What is the surface area of the rectangular prism below?
15
A. 525 units2
B. 432 units2
C. 490 units2
D. 496 units2
Answer:
B ( 432 units^2)
Step-by-step explanation:
Total surface area= 2*(6*6)+ 4*(15*6)
There are 2 squares at each end of the same size so total area will be 2*(6*6)
If we look at the rectangles( bottom, top and the sides), we can see that all are of same dimensions and there are 4 of them so it's 4*(15*6)
In short, total surface area= 2*(6*6)+ 4*(15*6) = 432 units^2
