Answer:

44.11

Step-by-step explanation:

you can use SOH-CAH-TOA to find the answer.

T has adjacent and hypotenuse shown in the figure.

thus you can write it as,

$cos(x) = 28 \div 39$

$x = cos^{ - 1} (28 \div 39)$

$x = 44.11$

(you can round the answer differently )

Answer: Hi I think that I can help you with your problem!

Let which means

Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.

To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.

So, we can rewrite as:

......(1)

Now, let us multiply the above with 10.

....... (2)

Now, let us subtract (1) from (2):

So, in simplified fractions:

Y = 3x +1; domain = {-1, 0, 1}<br> HELP PLEASE

ser-zykov [4K]

We have to put values of domain to find range

$\\ \ast\sf\longmapsto y=3x+1$

$\\ \ast\sf\longmapsto D_R=[-1,0,1]$

$\\ \ast\sf\longmapsto y=3(-1)+1=-3+1=-2$

$\\ \ast\sf\longmapsto y=3(0)+1=0+1=1$

$\\ \ast\sf\longmapsto y=3(4)+1=12+1=13$

Now

$\\ \ast\sf\longmapsto R_R=[-2,1,13]$

What would be the order?

Oduvanchick [21]

Answer:

<em>17/2, 8.8 with bar on right 8, |-9|, sqrt(82)</em>

Step-by-step explanation:

sqrt(82) = 9.05538...

17/2 = 8.5

8.8 with bar on right 8 = 8.8888888...

|-9| = 9

In order from least to greatest: 17/2, 8.8 with bar on right 8, |-9|, sqrt(82)

Everett and marie are going to make fruit bars for their family reunion. they want to make four times the amount the recipe make

meriva

Okay, since the problem states that they're going to make 4 times the recipe and the recipe is 2/3, You have to multiply 2/3 x 4/1 which equals to 8/3, When you convert it into a mixed numbe you have 2 2/3, Hope I helped.
