Answer: D. 38x + 1,450 > 4,000

Step-by-step explanation:

It has to be greater than 4,000 so A makes no sense

The parentheses are in the wrong place completely changing the meaning for B

C disregards the info we have about how she's already typed 1,450 words

The answer has to be D

Oliga [24]

Answer:

B. 48

100-52 = 48

Step-by-step explanation:

When you are finding the range you are taking the lowest and highest numbers and finding the difference. So you would put the numbers in order from least to greatest then find the highest and lowest amounts.

The cone shown has a height of 5 inches and a
Slav-nsk [51]

Answer:

Therefore approximate Volume of Cone is 11.78 inch³.

Step-by-step explanation:

Given:

Cone Shape :

Height = h = 5 inches

Radius = r = 1.5 inches

To Find:

Volume of Cone = ?

Solution:

Formula for Volume of Cone is given by

\textrm{Volume of Cone}=\dfrac{1}{3}\pi (Radius)^{2}\times Height

Substituting the given values we get

\textrm{Volume of Cone}=\dfrac{1}{3}\pi r^{2}\times h

\textrm{Volume of Cone}=\dfrac{1}{3}\times 3.14\times (1.5)^{2}\times 5=11.775\ inch^{3}

Therefore approximate Volume of Cone is 11.78 inch³.

Solve the following system of equations using substitution <br> x = 4 <br> 2x + 4y = 36
DiKsa [7]
Just plug in 4 for the x

2*4 +4y =36
8+4y =36
4y =36-8
4y=28
y= 28/4
y=7

Write an equation in which the quadratic expression 4x^2-26x+42 equals 0. Must show all work to receive credit.
Masteriza [31]

Answer:

(a) (x + 3)(2x + 7) = 0

(b) These solutions mean that for these two x values, f(x) is equal to 0. It's also where the graph of f(x) crosses the x-axis.

Step-by-step explanation:

(a) We set 4x² -26x + 42 equal to 0:

4x² -26x + 42 = 0

Let's divide both sides by 2 to simplify this a bit:

2x² - 13x + 21 = 0

Now, we need factors a and b of 2 and c and d of 21 such that ac + bd = -13. The factors of 2 are: 1 and 2, so let's say a = 1 and b = 2. The factors of 21 are: (1, 21), (3, 7), (-1, -21), and (-3, -7). We see that if c = -7 and d = -3, this works:

ac + bd = 1 * (-7) + 2 * (-3) = -7 - 6 = -13

So, the factored form is:

(x - (-3))(2x - (-7)) = 0

(x + 3)(2x + 7) = 0

(b) So now we need to solve this. Set each of the two parenthetical expressions equal to 0:

x + 3 = 0

x = -3

AND

2x + 7 = 0

x = -7/2

These solutions mean that for these two x values, f(x) is equal to 0. It's also where the graph of f(x) crosses the x-axis.
