Answer:

the answer is 3 im like 50 50 with that but i tried

hope this helped

Step-by-step explanation:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 7 by 3 and keep only what is to the left of the decimal point:

7 / 3 = 2.3333 = 2

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

 7 - (3 x 2) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 7/3 as a mixed number is:

2 1  

       3   well 2 and 1/3rd

Find the measurement of E<br> •56<br> •132<br> •51<br> •63
Burka [1]

Answer:

∠ E = 56°

Step-by-step explanation:

the external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ MGF is an exterior angle of the triangle , then

10x + 12 = 5x - 4 + 76

10x + 12 = 5x + 72 ( subtract 5x from both sides )

5x + 12 = 72 ( subtract 12 from both sides )

5x = 60 ( divide both sides by 5 )

x = 12

Then

∠ E = 5x - 4 = 5(12) - 4 = 60 - 4 = 56°

A can of tuna has a volume 18pi cm3 and a height of 2 cm. Find the area of the label that wraps around the entire can and does n
Sphinxa [80]

Answer:

The area of the label is 12\pi\ cm^{2}

Step-by-step explanation:

step 1

Find the radius

we know that

The volume of the cylinder (can of tuna) is equal to

V=\pi r^{2} h

In this problem we have

V=18\pi\ cm^{3}

h=2\ cm

substitute and solve for r

18\pi=\pi r^{2} (2)

Simplify

18=r^{2}(2)

r^{2}=9

r=3\ cm

step 2

<em>Find the lateral area of the can</em>

The lateral area of the cylinder (can of tuna) is equal to

LA=2\pi rh

we have

r=3\ cm

h=2\ cm

LA=2\pi (3)(2)=12\pi\ cm^{2}

Use the x-intercept method to find all real solutions of the equation -9^3-72^2-96x+36=3x^3+x^2-3x+8
Vadim26 [7]

Answer:

 x ≈ 0.290640965127

Step-by-step explanation:

y subtracting the right side of the equation, we get a function that is zero at a real solution for x. The only x-intercept is at approximately 0.290640965127.

___

The graph shows the x-intercept to be 0.2906. The value above was obtained by Newton's method iteration. The roots of this cubic will all be irrational.
