Volume means length x width x height and since it has already found the length and width, you multiply that by 4. So, 24 x 4 = 96
Answer:
32
Step-by-step explanation:
so volume =1/3 area of base times hieght that would be
1/3*96

The approximated circumference of the circle is 15.7 inches. Then the correct option is C.
What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The diameter of the circle is 5 inches. Then the circumference will be
[tex]\rm Circumference = \pi D\\\\Circumference = \pi \times 5\\\\Circumference = 15.707 \approx 15.7\\[/tex]

1/6+1/6= 2/6, both divided by 2 gives you 1/3
1/3+1/3= 2/3
Good luck luv
Hope this helps
Answer:
2/3
Step-by-step explanation:
To add fractions with different denominators, change the denominator to the least common multiple of the denominators.
The denominators here are 6, 3, and 6. The least common multiple of these three numbers is 6. Now, convert each of the fractions into fractions with a denominator of 6, specifically only 1/3.
1/6+2/6+1/6
Now add up the numerators,
1/6+2/6+1/6 = 4/6
Simplify.
4/6 = 2/3

If f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to
If function f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to f(x+3)= 2x^2 +9x +13.
Degree of polynomial is two so it will have only two solution
f(a)=0 if x=a
or
f(b)=0 if x=b
so put X=x+3
we will get
2[x+3]^2 - 3[x+3] + 4 = 2x^2 +9x +13
so if f(x+3)= 2x^2 +9x +13
The highest degree of a polynomial's monomials with non-zero coefficients is referred to as the polynomial's degree in mathematics. A term's degree is a non-negative integer and is calculated by adding the exponents of all the variables that occur in it.
The highest exponent of a polynomial's variable is referred to as the polynomial's degree. • A polynomial of degree zero is a constant polynomial. Zero polynomial is the name given to the constant polynomial f(x) = 0.

Finding slope intercept
Answer: the equation is y=3x+4
Step-by-step explanation:
The equation to the promblem is y=3x+4 becuase the y intercept is 4 and the slope is going up by 3.
What are the x- and y-intercepts for the graph of the equation y = 4 - 2x?
Select one:
X-intercept = 2; y-intercept = 4
x-intercept = -2; y-intercept = 4
x-intercept = 4; y-intercept = -2
X-intercept = 4; y-intercept = 2
Answer:
X intercept is -2
Y intercept is 4
Answer:
The first one, [tex]x[/tex]-intercept [tex]=2[/tex]; [tex]y[/tex]-intercept [tex] = 4[/tex]
Step-by-step explanation:
The [tex]x[/tex]-intercept is where [tex]y=0[/tex], so we can solve for it with the following equation:
[tex]0=4-2x→2x=4→x=2[/tex]
So the answer is the first one, but just to make sure, you can solve for the [tex]y[/tex]-intercept because their [tex]x[/tex]-values always equal to [tex]0[/tex] as well:
[tex]y=4-2(0)→y=4-0→y=4[/tex].

Complete the equation of the line whose y intercept is (0,-1) and slope of 4
Answer:
y = 4x - 1
Step-by-step explanation:
y + 1 = 4(x + 0)
y = 4x -1
Answer:
y = 4x - 1
Step-by-step explanation:
All you want to do is put the equation into the form y = mx + b where m is the slope and b is the y-intercept (an example would be y = 2x + 1 which would have 2 is the slope and 1 is the y-intercept)
Since you have:
slope or m = 4
y-intercept or b = -1
The equation would be y = 4x - 1

Solve the equation 4(h + 1.5) = -6.
h=
Answer:
h=3 is the answer
Step-by-step explanation:
The required solution to the given equation 4(h + 1.5) = -6 is
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question as:
4(h + 1.5) = -6
To solve the equation 4(h + 1.5) = -6, we need to isolate the variable "h". We can do this by performing the following steps:
First, we need to get rid of the parentheses around "h + 1.5". We can do this by multiplying everything inside the parentheses by 4:
4(h + 1.5) = 4h + 6
Next, we need to get rid of the coefficient of 4 in front of "h". We can do this by dividing both sides of the equation by 4:
4h + 6 = -6
h + 1.5 = -1.5
Finally, we can subtract 1.5 from both sides of the equation to isolate the variable "h":
h = -1.5 - 1.5
h = -3
Therefore, the value of "h" that satisfies the equation is -3.

O she needs to buy more baseboard, she doesn't have enough
O 4.95 inches
O 28.05 inches
O5.05 inches
Answer: 4.95 inches
Subtract: 36 - 31.05 = 4.95
Step-by-step explanation:
Whoever created this question hasn't done much real electrical work!
An outlet (also known as a receptacle) usually requires about 4 to 6 inches of wire within the junction box to make the connections, depending on what else may be connected in the box. We don't have to measure to 0.05 of an inch. The insulation may have to be stripped precisely to 3/8, 1/2 or 5/8 inch for connections.
The electrician used 3 feet of cable between junction boxes, and had 8 ¹/₂ inches pulled through the junction box. She needed 4 inches to connect the receptacle. How much the excess did she have to cut off?
