The sum of the measures of angle M and angle R is 90°.

1 answer:

3 0

X=5

55+(5x+10)=90

(this is a right triangle since all three angles must add up to 180 degrees)

55+5x+10=90
65+5x=90
-65 -65
——————
5x=25

(get the x alone by dividing both sides by 5)

x=5

Answer:

Amira used 4 balloons for each balloon animal.

Step-by-step explanation:

From the table, we can conclude that:

For 20 animals being sold by her, the leftover balloons were 180.

Then there is an increase in the number of animals being sold. She now sells 29 animals. So, the increase in animals being sold is given as:

29 - 20 = 9.

So, 9 more animals were sold. The balloons used for these 9 animals can be obtained by taking the difference of the leftover balloons for the two days.

The difference of the leftover balloons = 180 - 144 = 36.

So, 36 balloons were used for selling 9 more animals.

Similarly, there is an increase of another 9 animals when 38 animals were sold as 38 - 29 = 9. Also, the balloons used in this case is 36 only as the difference of the leftover balloons is 36.

144 - 108 = 36

Therefore, we conclude that for selling 9 balloon animals, Amira used 36 balloons.

Number of balloons used for 9 balloon animals = 36

∴ Number of balloons used for 1 balloon animal = $\dfrac{36}{9}=4$ (Unitary method)

Thus, Amira used 4 balloons for each balloon animal.

Can someone please help me? Thank you!

Answer:

Step-by-step explanation:

1) $5^{\frac{2}{3} }$ is in exponential form.

Now, radical form is $\sqrt[3]{5^{2} }$

2) $5^{\frac{1}{2} }$ is in exponential form.

Radical form is $\sqrt{5}$

3) $3^{\frac{2}{5} }$ is in exponential form.

Radical form is $\sqrt[5]{3^{2} }$

4) $3^{\frac{5}{2} }$ is in exponential form.

Radical form is $\sqrt{3^{5} }$

To find the inverse function, swap x x and y y , and solve the resulting equation for x x . If the initial function is not one-to-one, then there will be more than one inverse. So, swap the variables:

y=−x2−36 y = − x 2 − 36

becomes

x=−y2−36 x = − y 2 − 36 .

Now, solve the equation

x=−y2−36 x = − y 2 − 36 for y y .

y=−x−36‾‾‾‾‾‾‾‾√ y = − x − 36y=−x−36‾‾‾‾‾‾‾‾√ y = − − x − 36

ANSWER y=−x−36‾‾‾‾‾‾‾‾√ y = − x − 36 y=−−x−36‾‾‾‾‾‾‾‾√
