Pens cost $0.20 each. Pencils cost $0.15 each. Write an algebraic expression that represents the total cost of buying p pens and n pencils. (Will give brainliest if correct)
Answer:
y=0.20p + 0.15n
Step-by-step explanation:
I believe this is correct I am 90% positive that it is right.
The algebraic expression will be C = 0.20 p + 0.15 n
It is given that a pen cost $0.20 and a pencil cost $0.15.
We have to give expression for total cost of p pens and n pencils.
What will be the value if 2 times of x is added to x ?
The value will be 3x.
Cost of 1 pen = $0.20
Cost of p pens will be ;
= 0.20 p
Cost of 1 pencil = $0.15
Cost of n pencils = 0.15 n
If total cost is represented by C then ;
C = 0.20 p + 0.15 n
Thus , the algebraic expression will be C = 0.20 p + 0.15 n

Rhode Island has a population of about 60,000 8th graders in the state. New Jersey has a total of 920,000 8th graders. Calculate the difference in Rhode Island and New Jersey's state's population of 8th graders. Express your final answer in scientific notation.
Answer:
8.6 × 10^5
Step-by-step explanation:
New Jersey 8th graders = 920,000
Rhode island 8th graders = 60,000
Difference in Rhode island 8th graders and New Jersey 8th graders population
= 920,000 - 60,000
= 860,000
Answer in scientific notation
860,000
The decimal point will move 5 places in
= 8.6 × 10^5
On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with the number a. For example b = 2a equals negative 2 and StartFraction 3 Over 4 EndFraction. when a = –2a equals negative 2 and StartFraction 3 Over 4 EndFraction.. Which equation represents this direct variation between a and b?
Answer:
B
Step-by-step explanation:
The equation that represents this direct variation between a and b is:
b = -a. See explanation below.
What is a Direct variation?
Direction Variation is best defined as an equation in which one variable equals a constant times the other can be used to express a mathematical relationship between two variables.
Hence it is correct to state that The equation that represents this direct variation between a and b is: b = -a

solve for x please
Answer: 53°
Step-by-step explanation: If two parallel lines are cut by
a transversal, then same-side interior angles are supplementary.
So if we know one of our angles measures 127,
our other angle will measure 180 - 127, which is 53.
So x is 53 degrees.
Remember, whenever you have two parallel lines cut by a transversal,
same-side interior <'s are supp. or the sum of their measures is 180 degrees.

6 lumberjacks can cut down 15 mahogany trees in 2 hours. How much longer will
it take 8 lumberjacks to cut down 35 mahogany trees working at the same rate?
B. 1}hr
c.hr
A. 3hr
D. 21hr
9514 1404 393
Answer:
3.5 hr
Step-by-step explanation:
We assume that "the same rate" means effort per tree is a constant. "Effort" is measured as the product of lumberjacks and hours. Then ...
(lumberjacks)(hours)/trees = (6)(2)/15 = (8)(t)/35
Multiplying by 35/8, we have ...
(35/8)(12/15) = t = (3·4·5·7)/(2·3·4·5) = 7/2 = 3.5
It will take 8 lumberjacks 3.5 hours to cut down 35 trees.

If the measure of the third angle of the triangle is 45 ° more than three time the measure of either of the other two angles, find the measure of each angle of the triangle. (Recall that the sum of the measures of the angles of a triangle is 180°.)
Answer:
The first and second angles are 27° and the third angle is 126°.
Step-by-step explanation:
We have that the third angle (β) is 45° more than three times the measure of either of the other two angles (θ):
[tex] \beta = 45 + 3\theta [/tex] (1)
Also, the sum of the measures of the 3 angles is 180°:
[tex] \beta + \theta + \theta = 180 ^{\circ} [/tex] (2)
By entering equation (1) into equation (2) we have:
[tex] 45 + 3\theta + \theta + \theta = 180 [/tex]
[tex] 5\theta = 180 - 45 [/tex]
[tex] \theta = 27 [/tex]
Hence, the third angle is:
[tex] \beta = 45 + 3\theta = 45 + 3*27 = 126 [/tex]
Therefore, the first and second angles are 27° and the third angle is 126°.

Answer:
(7w + 9x)(7w - 9x)
Step-by-step explanation:
Given expression;
49w² - 81x²
Now to solve the problem;
49w² - 81x² = 7²w² - 9²x²
Using differences of two squares;
x² - y² = (x + y)(x - y)
So;
7²w² - 9²x² = (7w + 9x)(7w - 9x)

A map’s scale is 1 inch: 3.5 miles. If the actual distance between two places is 77 miles, then they will be ____ inches away from each other on the map.
==================================
Work Shown:
(1 inch)/(3.5 miles) = (x inches)/(77 miles)
1/3.5 = x/77
1*77 = 3.5*x ..... cross multiply
77 = 3.5x
3.5x = 77
x = 77/3.5
x = 22
22 inches on paper correspond to 77 miles in real life.
