Hana has some blue paint. She wants to lighten the shade, so she mixes in 1
cup of white paint. The color is still too dark, so Hana keeps mixing in 1 cup of
white paint at a time. After adding 4 cups, she decides the color is too light.
Answer:
The answer is below
Step-by-step explanation:
Hana has some blue paint. She wants to lighten the shade, so she mixes in 1 cup of white paint. The color is still too dark, so Hana keeps mixing in 1 cup of white paint at a time. After adding 4 cups, she decides the color is too light.
How would she express the amount of paint to add to be between too dark and too light.
Solution:
After adding a cup of white paint, the color is still dark, she adds the second cup of paint and the color is still dark. She adds the third cup of paint and the color is still dark but when she adds the fourth cup of white paint, the color became too light.
This means that the amount of paint to add to be between too dark and too light is between the third and fourth cup.
Let w represent the amount of paint to add to be between too dark and too light. Hence:
3 < w < 4

A 35-foot tall pole is leading towards a building. To stop the pole from leaning further, a 48-foot long cable is secured from the top of the pole to a stake in the ground opposite of the building. If the stake is 30 feet from the pole, what angle does the cable make with the pole?
Round the answer to the nearest tenth.
9514 1404 393
Answer:
38.5°
Step-by-step explanation:
A triangle solver can give an answer easily. The angle is 38.5°.
__
The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.
C = arccos((a² +b² -c²)/(2ab))
Here, we have a=35, b=48, c=30, so the angle is ...
C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°
The angle the cable makes with the pole is about 38.5°.

simplify the expression a² • 3a and explain your steps pls
Answer:
3a^3
Step-by-step explanation:
Ok I got you bud now the the first thing to notice that they're all the same variable. so the way I learned to look at is like this
1a^2 x 3a^1
so the reason I put it like this is so I remember that in front of every variable is a coefficient. so you would first multiply the coefficient
3x1=3
3
then multiply the a's you have one a that is being squared and one a to the first power so since your multiplying them you just add the exponents
a^1 + a^2 = a^3
so when you put it all together it says 3a^3
hope this helps
An Eurasian lynx travled 46 miles. It took the
cat 43 days. to cover this distance How many miles per
day did it travel.
Answer:
A Eurasian lynx covered 1.07 miles per day.
Step-by-step explanation:
The distance traveled by a Eurasian lynx = 46 miles
The days to cover the 46 miles distance = 43 days
Divide the total distance miles by the total number of days to determine the miles per day.
Thus,
Miles per day = Tota distance / Totdal days
= 46 / 43
= 1.07 miles per day
Thus, An Eurasian lynx covered 1.07 miles per day.

Step-by-step explanation:
the seventh grade class is putting on a variety show to raise money. it cost 700 dollars to rent the banquet hall that they are going to use. if they charge 15 dollars for each ticket, how many tickets do they need to sell in order to raise 1000 dollars. Write an inequality and a solution to the inequality.
Answer:
Since the question is partial, i will assume 2 scenarios:
They need to raise 1000 income
They need to make 1000 as profit
If $1000 as income:
Each ticket costs $15, so tickets would bring them $1000 income. Fractional ticket is not possible, so rounding gives us 67 tickets as the answer.
If $1000 as profit:
Their cost of renting is $700. We know that .
So, . So, to raise $1700, we need tickets. Fractional ticket is not possible, so rounding gives us 114 tickets as the answer.
ANSWER:
If need to raise atleast $1000 as income, they need to sell 67 tickets.
If need to raise atleast $1000 as profit, they need to sell 114 tickets.
The most probable answer would be 114 tickets

What is the slope of the line 3x – 9y = 4?
Answer:
Slope = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Write the equation in y =mx + c form
3x - 9y = 4
-9y = -3x + 4
[tex]y = \frac{-3x}{-9}+ \frac{4}{-9}\\\\y =\frac{x}{3} - \frac{4}{9}\\m = \frac{1}{3}[/tex]

Is 3/6 divided by 5 greater than 1?
It is not greater than one.
When you divide 3/6 by 5, your quotient is 0.1, which has a value that is less than 1.
Hope this helps!
- sahira :>
Step-by-step explanation:
3/6 divided by 5
The numbers in 3/6 divided by 5 are labeled below:
3 = numerator
6 = denominator
5 = whole number
To make it a fraction form answer, you keep the numerator and multiply the denominator by the whole number to make a new denominator:
3/6 times 5 = 3/30
Thus, the answer to 3/6 divided by 5 in fraction form is:
3/30
to make the answer to 3/6 divided by 5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
3/30 = 0.1
The answer is rounded to the nearest four decimal points if necessary.
3/30 can be simplified to 1/10

(11x + 8) + (8x + 12) =27
Answer:
11x + 8 +8x +12 =27 (drop the parenthesis, there's no actual need for them)
19x +20 =27 (i combined like terms and then subtracted 20 from both sides)
19x = 7 (divide both sides by 19 to get x alone)
x= 7/19 or 0.36842105 (the answer)

Find the surface area of the 3D solid. Round to one decimal place.
Answer:
172.5
Step-by-step explanation:
The formula for the surface area of a right circular cone (the following shape) is πr( r + √h^2 + r^2). Since the radius (r) is already given (3) and the height (h) is already given (15), you just replace each r with 3 and h with 15. After solving this out, you should get 172.45, which rounds to 172.5 to the first decimal place
