Given:

A figure of a right angle triangle.

To find:

The value of x°.

Solution:

The given triangle is a right angle triangle. So, the measure of one angle is 90 degrees.

The measure of other two angles are 3x° and 7x°.

According to the angle sum property of a triangle, the sum of all three interior angles of a triangle is 180 degrees.

Using the angle sum property of the triangle, we get

[tex]90^\circ+3x^\circ+7x^\circ=180^\circ[/tex]

[tex]10x^\circ=180^\circ-90^\circ[/tex]

[tex]10x^\circ=90^\circ[/tex]

Divide both sides by 10.

[tex]x^\circ=\dfrac{90^\circ}{9}[/tex]

[tex]x^\circ=10^\circ[/tex]

Therefore, the value of x° is equal to 10°.

Answer:

C. y= 1.5x

Step-by-step explanation:

Everytime multiply the first number 1.5 (y) by the X variables it gives you another Y variable. For example, 1.5 times 2 = 3. 1.5 times 3 = 4.5. And 1.5 times 4 = 6!

Answer:

The expected rate of return is 6.3%.

The standard deviation is of 11.29%.

Step-by-step explanation:

Expected rate of return

Multiply each rate by its probability. So

[tex]E = 0.1(-20) + 0.2(0) + 0.4(7) + 0.2(15) + 0.1(25) = 6.3[/tex]

The expected rate of return is 6.3%.

Standard deviation:

Square root of the difference squared between each value and the mean, multiplied by the probability. So

[tex]S = \sqrt{0.1(-20-6.3)^2 + 0.2(0-6.3)^2 + 0.4(7-6.3)^2 + 0.2(15-6.3)^2 + 0.1(25 - 6.3)^2} = 11.29[/tex]

The standard deviation is of 11.29%.

Answer: Gas station P

Step-by-step explanation:

When you plot gas station M on the graph all the values are under the line meaning it gas at station M costs less than station G.

Gas station P charges more than gas station M.

A unit rate means a rate for one of something.

Given is a table and a graph,

When we compare each, we get,

Gas station P is charging $20 for 5 gallons, and gas station M charges $19 for same.

Hence, gas station P charges more than gas station M.

Answer:

Lets find volume of smaller cubiod first.

Volume = l x b x h = 24 cm³

Again,

Lets find volume of bigger cuboid.

Volume = l x b x h = 648cm³

Now,

The no. of cuboids that can be made from the bigger cuboid is

= Volume of bigger cuboid / volume of smaller cuboid

= 648/ 24

= 27 cuboids

Answer:

0.03

Step-by-step explanation:

.25% for the tails times .5 for the odd number on the dice times 0.25 for the clubs because it is a 13/52 chance you will pull a clubs and put that all together and you get 0.03125 simplified and you get 0.03

Answer:

0.03

Step-by-step explanation:

The probability of landing on 1 tail is 1/2, since it is 1 out of 2 options, a tail or a head. If you want the probability of two tails, it would be 1/2 * 1/2 = 1/4.

Next we can take the probability of rolling an odd number on a fair die. A fair die has 3 even numbers: 2,4,6; and 3 odd numbers: 1,3,5. Since 3/6 or 1/2 of the numbers are odd, there is a 50% chance that it would roll an odd number.

Finally, drawing a club out of standard deck of cards is 1/4, since there are 4 choices: hearts, spades, clubs, or diamonds. You now get the idea, and you can figure out that the probability would be 1/4.

Our last step is to multiply all the answers we get, since to get all of them at once would lower your chances. 1/4 * 1/2 * 1/4 = 1/32 = 0.03125; rounded to 0.03.

Answer:

[tex]c =\frac{18 + 3 b x}{3}[/tex]

Step-by-step explanation:

3 ( c - b x ) = 18

Solve the brackets.

3c - 3 b x = 18

Take -3 b x to the right side.

3c = 18 + 3 b x

Divide both sides by 3.

[tex]c =\frac{18 + 3 b x}{3}[/tex]

Answer:

The 4th option, 10g + 24 = t

Step-by-step explanation:

It costs 24 dollars per month no matter what.

$10 * the amount of GB you want

Add those two values to get the total cost per month.

In this case you want 5 GB, so substitute the g in the equation for 5. You will get:

10 * 5 +24 = t

50 + 24 = t

74 = t

So it costs 74 dollars per month to get 5 GB.

Answer:

C

Step-by-step explanation:

We want to evaluate the definite integral:

[tex]\displaystyle \int_0^1 (x+2)(3x^2+12x+1)^{1/2}\, dx[/tex]

Again, notice that the radicand is quite similar to the outside factor. So, we can use u-substitution again. We will let:

[tex]\displaystyle u=3x^2+12x+1[/tex]

Then:

[tex]\displaystyle \frac{du}{dx}=6x+12[/tex]

Hence:

[tex]\displaystyle du=6x+12 \, dx[/tex]

And we can divide both sides by 6:

[tex]\displaystyle \frac{1}{6}\, du=x+2\, dx[/tex]

Note that the limits of integration of our original integral (from x = 0 to x = 1) is in the domain of x. Since we changed variables, we should also change the limits of integration to u. So:

[tex]u(0)=3(0)^2+12(0)+1=1[/tex]

And:

[tex]u(1)=3(1)^2+12(1)+1=16[/tex]

Hence, our new limits of integration is from u = 1 to u = 16.

Perform the substitution:

[tex]\displaystyle =\int_{1}^{16} u^{1/2}\Big(\frac{1}{6}\, du\Big)[/tex]

Simplify:

[tex]\displaystyle =\frac{1}{6}\int_1^{16}u^{1/2}\, du[/tex]

Integrate:

[tex]\displaystyle =\frac{1}{6}\Big(\frac{2}{3}u^{3/2}\Big)\Big|_{1}^{16}[/tex]

Simplify:

[tex]=\displaystyle \frac{1}{9}\Big(u^{3/2}\Big|_1^{16}\Big)[/tex]

Evaluate:

[tex]\displaystyle =\frac{1}{9}\Big(16^{3/2}-1^{3/2}\Big)=\frac{1}{9}(64-1)=7[/tex]

The answer is C.
