Answer:

  (a)  4x+89.95=628.35; x = $134.60

Step-by-step explanation:

The total cost (628.35) is the cost per cavity (x) times the number of cavities (4), added to the flat fee (89.95). The equation for that is ...

  4x +89.95 = 628.35

The solution to that is ...

  x = (628.35 -89.95)/4 . . . . . subtract the constant, divide by 4

  x = 134.60

Step-by-step explanation:

If she ran 5 miles on Friday, and 20 in the whole week, you can make the equation:

5 + x = 20

x = 15

Answer:

Friday

Step-by-step explanation:

If 6 days ago was Wednesday, that means 6 days ago was Thursday. Every seven days, it will be Thursday again, so we can do 701/7 and see how many weeks fit equally. It is 100 weeks and 1 day. That means that Thursday would be in 100 weeks, or 700 days. Since there is one day left, it would be Friday. Friday is your answer.

The day after 701 days from today if, 6 days ago was Wednesday is Friday, so option C is correct.

One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components.

Given:

If 6 days ago was Wednesday,

If 6 days ago was Wednesday, then it will be Thursday today,

Calculate the day after 701 days as shown below,

The day = 701 / total days

As you can see, the Thursday will be repeated after 7 days,

Here, 1 will be the reminder, then one day after Thursday will be Friday.

Thus, after 701 days, it will be Friday.

Answer:

the anwser is 242

Step-by-step explanation:

I dont see a q anywhere but you would sub p and 9 and do the equation so times 10 and 9 and then distribute 22 or in your calculator jus enter 22(90-79) and you would get 242

Answer: 3) x = 87°; y = 93°; z = 63°

Step-by-step explanation:

x + 33 + 60 = 180 since they form a triangle.

x + 93 = 180

Subtract 93 from both sides

x = 87°

x and y are linear pairs so they're supplementary.

y + x = 180

y + 87 = 180

Subtract 87 from both sides

y = 93°

z + y + 24 = 180 since they also form a triangle

z + 93 + 24 = 180

z + 117 = 180

Subtract 117 from both sides

z = 63°

Step-by-step explanation:

Y= 5/2X -1/4

X= 1/10

0.85(a + 60) ≤ 85

0.85a + 51 ≤ 85

-51 on both sides

0.85a ≤ 34

/0.85 on both sides

Given:

[tex]\sigma_A=3[/tex]

[tex]n_A=6[/tex]

[tex]\sigma_B=5[/tex]

[tex]n_B=4[/tex]

[tex]\overline{x}_A=\overline{x}_B[/tex]

To find:

The variance. of combined set.

Solution:

Formula for variance is

[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x})^2}{n}[/tex]      ...(i)

Using (i), we get

[tex]\sigma_A^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{n_A}[/tex]

[tex](3)^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]

[tex]9=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]

[tex]54=\sum (x_i-\overline{x}_A)^2[/tex]

Similarly,

[tex]\sigma_B^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{n_B}[/tex]

[tex](5)^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]

[tex]25=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]

[tex]100=\sum (x_i-\overline{x}_B)^2[/tex]

Now, after combining both sets, we get

[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x}_A)^2+\sum (x_i-\overline{x}_B)^2}{n_A+n_B}[/tex]

[tex]\sigma^2=\dfrac{54+100}{6+4}[/tex]

[tex]\sigma^2=\dfrac{154}{10}[/tex]

[tex]\sigma^2=15.4[/tex]

Therefore, the variance of combined set is 15.4.

Given:

The equation is

[tex]\dfrac{3}{2}+b=\dfrac{7}{4}[/tex]

To find:

The value of b.

Solution:

We have,

[tex]\dfrac{3}{2}+b=\dfrac{7}{4}[/tex]

Subtracting both sides by [tex]\dfrac{3}{2}[/tex], we get

[tex]b=\dfrac{7}{4}-\dfrac{3}{2}[/tex]

[tex]b=\dfrac{7-2(3)}{4}[/tex]

[tex]b=\dfrac{7-6}{4}[/tex]

[tex]b=\dfrac{1}{4}[/tex]

Therefore, the value of b is [tex]\dfrac{1}{4}[/tex].
