OKAY! So, this problem can also be written as 17/3 + 15/4. That can be converted to 64/12 + 45/12, which is 109/12. that is 9 and 1/12.

Well you need to make 5 2/3 and 3 3/4 into improper fractions by doing the sum 3 x 5 + 2 over the original number. e.g 3 3/4 4 x 3 = 12 + 3 = 15 15/4

Do that for both and then add them together by creating the same bottom number (you can do this by multiplying the two bottom numbers) then add the top numbers but don't change the bottom numbers.

17/3 +15/4

68/12 + 45/12 = 45 + 68 = 113/ 12

The area of the square is 100 square centimeters. What is the area of the circle?

swat32

Answer:

Since the question is incomplete, see the figure attached and the explanation below.

Explanation:

Since the figure is missing, I enclose the figure of a square inscribed in a circle.

Since the <em>area of a square</em> is the side length squared, you can determine the side length:

Area = (side length)²

100 cm² = (side lenght)²

$side\text{ }length=\sqrt{100cm^2}=10cm$

From the side length, you can find the diagonal of the square, which is equal to the diameter of the circle, using the Pythagorean theorem:

diagonal² = (10cm)² + (10cm)² = 2 × (10cm)²

$diagonal=\sqrt{2\times (10cm)^2}\\ \\ diagonal=10\sqrt{2} cm$

The area of the circle is π (radius)².

radius = diameter/2 = diagonal/2

$area= \pi \times (5\sqrt{2}cm)^2=50\pi cm^2$

Im so confused right now. how do I do this?

Sedbober [7]

Step-by-step explanation:

V= L×W×H
you only need to know one side to figure out the
volume of a cube
volume is in 3Dimensions
Multiple the sides in any order
which side you call length, width, or height doesn't matter

that's how you find the answer.

does that help?

Solve for ppp. 16-3p=\dfrac23p+516−3p= 3 2 p+516, minus, 3, p, equals, start fraction, 2, divided by, 3, end fraction, p, plus

Ksivusya [100]

Given:

The given equation is:

$16-3p=\dfrac{2}{3}p+5$

To find:

The value of p.

Solution:

We have,

$16-3p=\dfrac{2}{3}p+5$

Multiply both sides by 3.

$3(16-3p)=3\left(\dfrac{2}{3}p+5\right)$

$48-9p=2p+15$

Isolating the variable terms, we get

$48-15=2p+9p$

$33=11p$

Divide both sides by 11, we get

$\dfrac{33}{11}=p$

$3=p$

Therefore, the required solution is $p=3$ .

Solve the system by the substitution method.<br> x-2y = -2<br> y = - 3x + 8

aliina [53]

x-2y = -2

x-2(-3x+8)=-2

mutiply the bracket by -2

(-2)(-3x)=6x

(-2)(8)=-16

x+6x-16=-2

7x-16=-2

move -16 to the other side

sign changes from -16 to +16

7x-16+16=-2+16

7x= -2+16

7x= 14

divide both sides by 7

7x/7=14/7

x=2

Find y by using the substitution method

y=-3x+8

y=-3(2)+8

-6+8
