Perform the indicated operation 2 3/8 x 5 3/4

Butoxors [25]

Hello!

Change each mixed number to an improper fraction to make it easier

2 3/8 = 19/8

5 3/4 = 23/4

Now, multiply

19/8 × 23/4 = 437/32 = 13 21/32

Answer ⇒ 13 21/32

Yo please help

Answer:

Options 1, 3 and 4 are true

Step-by-step explanation:

The legs EF and DF of the right triangle DEF have lengths of 24 units and 7 units, respectively. By the Pythagorean theorem,

$DE^2=EF^2+DF^2\\ \\DE^2=24^2+7^2\\ \\DE^2=576+49\\ \\DE^2=625\\ \\DE=25\ units$

Find trigonometric functions:

$\sin \angle D=\dfrac{\text{Opposite leg}}{\text{Hypotenuse}}=\dfrac{EF}{DE}=\dfrac{24}{25}$

$\cos \angle E=\dfrac{\text{Adjacent leg}}{\text{Hypotenuse}}=\dfrac{EF}{DE}=\dfrac{24}{25}$

$\tan \angle D=\dfrac{\text{Opposite leg}}{\text{Adjacent leg}}=\dfrac{EF}{DF}=\dfrac{24}{7}$

$\sin \angle E=\dfrac{\text{Opposite leg}}{\text{Hypotenuse}}=\dfrac{DF}{DE}=\dfrac{7}{25}$

Thus, options 1, 3 and 4 are true

Write a linear equation in slope-intercept form: 5y – 3x + 20 = 0

Arturiano [62]

Slope intercept form is y = mx+ b

So in order to turn 5y-3x + 20 = 0 into Slope intercept form, all we need to do is solve for y!

Let's do it!

add 3x to the right side of the equation

5y - 3x + 20 = 0

5y + 20 = 3x

move 20 to the right side

5y = 3x - 20

Divide both sides of the equation by 5

y = 3/5x - 4

This is our answer!

I hope I helped! Leave a comment if you have any questions or concerns
