Answer:
47.3 grams
Step-by-step explanation:
Given: A solution contains 4.3 grams of salt per liter.
To find: Amount of salt in 11 liters of the solution
Solution:
Amount of salt in 1 liter of the solution = 4.3 grams
So, amount of salt in 11 liters of the solution = 11 × Amount of salt in 1 liter of the solution = 11 × 4.3 = 47.3 grams
Hence, 11 liters of the solution contains 47.3 grams of salt.
Answer: 47.3

what is the solution for the inequality -3x + 2 < 11?
Start by subtracting 2 from both sides.
This gives us -3x < 9.
Now, divide both sides by -3.
However, when you divide both sides of an inequality by a negative number, you must switch the direction of the inequality sign.
So we have x > -3.

Another candle has a volume of 75 cubic inches and a height of 6 inches. What is the radius, in inches, of this candle? Round your answer to the nearest inch. Use 3.14 for π.
Answer: 3 inches
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cone = 1/3 x π x radius^2 x height
Replacing with the values given:
75 = 1/3(3.14) r^2 (6)
Solving for r:
75 / (1/3 (3.14) 6) = r^2
75/ 6.28 = r^2
11.94 = r^2
√11.94 =r
3.45 inches = r
3 inches = r

Given the following exponential function, identify whether the change represents growth or decay , and determine the percentage rate of increase or decrease y =550(1.075)x
Answer:
It is growth and the percentage rate of increase is 7.5%
Step-by-step explanation:
The exponential equation is as follows;
y = 550(1.075)^x
Now, I can identify that the exponential equation is that of growth.
This is because what is in the bracket i.e can be represented as 1+ 0.075
The 0.075 represents the margin of increase as we move on from one value to another
The percentage rate can be gotten by expressing 0.075 as a percentage
That would be expressing is as a fraction
This is just 7.5/100 which means what we have is 7.5%

At 7 p.m. the temperature was 5° F. At midnight the temperature was -7° F. What was the change in temperature?
Answer:
Change in temperature was 12 degrees
Step-by-step explanation:
If you start with five degrees and end into negative 7 degrees, you can find the result within two steps
5 degrees minus 5 = 0 degrees
then, 0 degrees minus 7 = -7 degrees
Because you subtracted 5 from five, and 7 from seven, you add those two values together
7 + 5 = 12 degrees
So the change in temperature was 12 degrees

The sum of a rational number and an irrational number produces an irrational number.
Answer:
True
Step-by-step explanation:
Example: sqrt(5) (which decimals continue forever) will mean that if you did 5+sqrt(5) it would still have those decimals.
Answer:
True. By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal, so the result is irrational.

Solve for q.
–15 − 18q = –20q + 15
q =
Answer:
q = 15
Step-by-step explanation:
→First, add 18q to both sides:
-15 - 18q = -20q + 15
-15 = -2q + 15
→Subtract 15 from both sides:
-30 = -2q
→Divide both sides by -2:
15 = q
We first want to get q on its own then solve like shown:
-15-18q=-20q+15
Now add 15 to both sides and add 20 q to both sides.
2q=30
Now divide 30 by 2.
q=15

the zero of the polynomial 6x power 2 + 19 X - 77 is
Answer:
The zeros of the polynomial are x = 7 or x = -11/2
Step-by-step explanation:
The zeros of a polynomial refers to the solution of the polynomial.
6x^2 + 19x -77
6x^2-14x+ 33x -77
2x(x-7) + 11(x-7)
= (2x + 11)(x-7)
2x + 11 = 0
x-7 = 0
2x = -11
x = -11/2 = -5.5
and x-7 = 0
x = 7
So the zeros of the polynomial are x = 7 or x = -11/2
Cam is making a party hat, shown at left, in the shape of a cone for his
birthday. The circumference of the part of his head where the hat will
rest is 56 centimeters (cm). If the height of the hat is 25 cm, which of
the following is closest to the volume of Cam's hat, measured in cubic
centimeters (cm)?
Answer:
V≈2,080cm^3 Hope I helped :)
Step-by-step explanation:
The volume of a cone of radius r and height h is:
V=1/3πr^2h
Since the circumference of Cam's head is 56
2πr=56
r=56/2π
r=28/π
The volume of the hat is therefore:
V=1/3π(28/π )^2(25)
V=1/3((28)^2/π)(25)
V=1/3(19,600/π)
V≈2,080cm^3
The volume of the Cam's hat measured in cubic centimetres is 2081 cm³
Volume of a cone:The volume of a cone is as follows:
v = 1 / 3 π r²hwhere
h = height
r = radius
The circumference of the part of his head where the hat will rest is 56 cm. Let's find the radius
circumference = 2πr56 = 2 × π × rr = 28 / πh = 25 cm
V = 1 / 3 × π × (28 / π )² × 25
V = 1 / 3 × π × 784 / π² × 25
V = 19600 / 3π
V = 19600 / 9.42
V = 2080.67940552
V ≈ 2081 cm³

Latrell wants to paint his bedroom ceiling to look like the sky. He wants it to be 85% blue and 15% white. If he needs 4.25 gallons of blue, how many gallons of white does he need?
Answer:
0.75 gallons
Step-by-step explanation:
As the statement indicates that Latrell wants the bedroom ceiling to be 85% blue and 15% white and you know that he needs 4.25 gallons of blue which represents the 85%, you can use a rule of three to find the amount that represents the 15% to know the gallons of white that he needs:
4.25 gallons → 85%
x ← 15%
x= (4.25*15)/85
x=0.75
According to this, the answer is that if Latrell needs 4.25 gallons of blue, he needs 0.75 gallons of white.
