Answer: There is 1.587 ounces of sodium chloride that he will need.

Step-by-step explanation:

Since we have given that

Quantity of sodium chloride in grams = 45 grams

We need to find the number of ounces of sodium chloride.

As we know that

1 ounce = 28.35 gram

So, 1 gram = \dfrac{1}{28.35}\ ounce

So, 45 grams = \dfrac{45}{28.35}=1.587\ ounces

Hence, there is 1.587 ounces of sodium chloride that he will need.

Harrison has 30 cds in his music collection. If 40% of the cds are country and 30% are pop, how many are other types of music
Pavel [41]
Well you have to find out how many cd is 40% and 30% 
30% = 30x.3=9
40% = 30x.4=16
now add 16 and 9
16+9=25 now subtract 25 from 30 and see that you have 5 cd of a different type of music to find that as a % divide 5 by 35 to get .14 I rounded it to the nearest hundreth now move the decimal over 2 spots to get 14%

Which story represents the equation six sevenths times one fourth?
Vesnalui [34]

Answer:  (C) Victoria has six sevenths of a pizza. She ate one fourth of it for dinner. How much pizza did Victoria eat for dinner?

Step-by-step explanation: One clue is "of" in the story and which matches "times" in the equation sentence. The question is is about multiplication.

Words such as "more" "and" & "total" are usually clues that the question is about addition. "Give" "take" "difference" & "have/are left" are clues that there is subtraction in the process.

Simplify this expression: 3(x + 4.5) + 2(2.6x – 3) 1. Distribute the 3 and 4 through the parentheses: 3(x) + 3(4.5) + 2(2.6x) -
Alex Ar [27]
In order to combine like terms, they have to first be organized. First combine the terms with the variable x, then the terms with no variables.

3x+13.5+5.2x-6
3x+5.2x=8.2x
13.5-6=7.5

The final simplified expression is 8.2x+7.5.

Mice21 [21]

Answer:

The Mean is not equal to $31,129.

Step-by-step explanation:

Consider the provided information.

The mean is $31129

Thus, the null hypothesis H_0: \mu = 31129

Alternative hypothesis H_a: \mu \neq 31129

A random sample of 15 firstyear CMAs in Denver produces a mean salary of $32,279, with a standard deviation of $1,797.

Thus the value mean of sample is 32279, standard deviation is 1797 and number of samples are 15.

Now use the 2 sided t-test.

t=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

Now substitute the respective values in the above formula.

t=\frac{32279-31129}{\frac{1797}{\sqrt{15}}}

t=\frac{1150}{464}

Test Value = 2.4785  approximately

Now, find the corresponding p-value in your t-table with DF(degree of freedom) 14.

p = 0.0265  

as the value of  p < 0.05, so you reject null hypothesis.  

Thus, the Mean is not equal to $31,129.

A carpenter is making a backyard deck. In the measurements, he has determined that he needs to make a support triangle with an a
s2008m [1.1K]

Answer:

base = 3x - 1

height = x

area of triangle = (1/2)bh

22 = (1/2)(3x-1)(x)

44 = (3x-1)(x)

44 = 3x^2-x

0 = 3x^2-x-44

0 = 3x^2-12x+11x-44

0 = (3x^2-12x)+(11x-44)

0 = 3x(x-4)+11(x-4)

0 = (x-4)(3x+11)

x = {-11/3, 4}

throw out the negative solution (extraneous) leaving

x = 4 m (height)

.

Base:

3x - 1 = 3(4) - 1 = 12 - 1 = 11 

Step-by-step explanation:

I hope it will help you
