Step-by-step explanation:

3/12 7/10

Make the Denominators same

3*5/12*5 = 15/60

7*6/10*6 = 42/60

Common Denominator is 60

Let a= x^2 +4. Rewrite the following equation in terms of a and set it equal to zero.

swat32

Answer:

C and G

Step-by-step explanation:

(x^2+4)^2+32=12x^2+48 is written as $(x^2+4)^2+32=12x^2+48$ .

We can simplify the expression using the term a by replacing x^2 + 4 with a.

$(x^2+4)^2+32=12x^2+48\\(x^2+4)^2+32=12(x^2+4)\\a^2 + 32 = 12a\\a^2 - 12a + 32 = 0$

This factors into (a-4)(a-8). Solve by setting each factor equal to 0 and solve for a.

a-4 = 0 a=4

a-8=0 a=8

Of the 50 students in the cafeteria, 7 have red hair. Suppose there are 750 students in the school. Write a proportion that coul

gulaghasi [49]

Given:

Of the 50 students in the cafeteria, 7 have red hair.

Total number of students = 750

To find:

The proportion that could be used to predict the number of students who have red hair.

Solution:

Let x represent the number of students who have red hair.

The ratio of student having red hair to the total number of students are

$Ratio_1=\dfrac{7}{50}$

$Ratio_2=\dfrac{x}{750}$

The number of students having red hair is proportional to the total number of students. So, the above ratios are equal.

$\dfrac{x}{750}=\dfrac{7}{50}$

Multiply both sides by 750.

$\dfrac{x}{750}\times 750=\dfrac{7}{50}\times 750$

$x=7\times 15$

$x=105$

Therefore, the required equation is $\dfrac{x}{750}=\dfrac{7}{50}$ and the number of students who have red hair is 105.

Find the missing side lengths

MAXImum [283]

Answer:

u is 17√2 and v is 17

Step-by-step explanation:

To find u:

${ \bf{ \sin( \theta) = \frac{opposite}{hypotenuse} }}$

feed in the terms:

$\sin(45 \degree) = \frac{17}{u} \\ \\ u = \frac{17}{ \sin(45 \degree) } \\ \\ u = 17 \sqrt{2}$

To find v:

$\cos( \theta) = \frac{adjacent}{hypotenuse}$

feed in the terms:

$\cos(45) = \frac{v}{u} \\ \\ v = u. \cos(45) \\ v = (17 \sqrt{2} )÷( \sqrt{2} ) \\ v = 17$

Write an expression that represents the volume of a rectangular-shaped box with a length 3 inches less than its height and a wid

slava [35]

Answer: h(h-3)(h+4)

Step-by-step explanation:

To find the volume of rectangular-shaped box we will have to multiply the length by the width by the height.

Given the statements we can determine the length with the equation

L = h -3 where l is the length and h is the height.

the width can also be represent by the equation

w = h + 4

The height is is h and the length is h- 3 and the width is also h+4 so the expression will be h(h-3)(h+4)
