Help pls I don’t remember how to do this so how do u find x, y, and z in this

Answers

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°

Hope this helped!

aning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and
ue of x, the cost of each cavity filling?
4x+89.95=628.35; X = $134.60
4(89.95) + X = 628.35
X = $268.55
4x+89.95=628.35; X= $179.58
A(89.95)+ x = 628.35
X = $538.40

Answers

9514 1404 393

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

If 6 days ago was Wednesday, what day will it be 701 days from now?

A Wednesday
B Thursday
C Friday
D Saturday
E Sunday

show work!!

Answers

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.

What is division?

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.

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].

Step-by-step explanation:

Set A of six numbers has a standard deviation of 3 and set B of four numbers has a standard deviation of 5. Both sets of numbers have an equal mean. If the two sets of numbers are combined, find the variance.​

Answers

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.
