Answer 1

Answer:

1) x=−y-2

2)x=−y+2

Step-by-step explanation:

Let's solve for x.

y=−x−2

Step 1: Flip the equation.

−x−2=y

Step 2: Add 2 to both sides.

−x−2+2=y+2

−x=y+2

Step 3: Divide both sides by -1.

x=−y−2

Let's solve for x.

3x+3y=6

Step 1: Add -3y to both sides.

3x+3y+−3y=6+−3y

3x=−3y+6

Step 2: Divide both sides by 3.

x=−y+2

A crate weighing 500 pounds was delivered to the gym & set on the floor. To

move it, we need to get a set of dolly wheels under the edge. If we use a 15 foot

pry bar to lift the edge and place a 12 high fulcrum back 2 feet from the box,

how much downward force will need to be applied to the bar to raise the crate?

Answers

The downward force that will be needed to be applied to the bar to raise the crate is 389.65N.

How to calculate the force?

From the information given, we'll first need to find the length of BC. This will be:

BC = 15 - (✓2 + ✓1)

BC = 15 - ✓5

The weight of the box will be:

= mg = 500 × 32.174 = 16087.05ft/s²

The force will then be:

= (16087.05 × ✓5)/(15 - ✓5)

If H is the circumcenter of triangle JKL then true statement is JH ≈ LH.

What is Property of Circumcenter?

The circumcenter of a triangle is the point of intersection of the perpendicular bisectors of the triangle's sides. It is the center of the circumcircle, which is the circle passing through all three vertices of the triangle.

The circumcenter is equidistant from the three vertices of the triangle.

This means that the distance from the circumcenter to each vertex is the same.

i.e., the distance of point H is equal from J, K and L.

Then, the length of each of is equal which is

Is 2/3 < 5/8? Help me with this

Answers

Answer:

No its 2/3 > 5/8

Step-by-step explanation:

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as:

2/3 = 0.667

5/8 = 0.625

Then, we compare the two decimal numbers to get the answer.

0.667 is greater than 0.625. So 2/3 > 5/8

Answer:

No, 2/3 is bigger than 5/8

Step-by-step explanation:

If you convert 2/3 into a deciamal it is 0.666

and if you convert 5/8 into a decimal it is 0.625

therefore 2/3 is the bigger fraction and the statement is not correct.

O 114 cm?

Answers

Answer:

Volume of the cylinder is 87.9 cm³

Step-by-step explanation:

Given that Radius of the cylinder is 2 cm and height is 7 cm. To find Volume of the Cylinder we will substitute the value of height and radius in given formula:

[tex] \\ \: \: \dashrightarrow \: \: { \underline{ \boxed { \pink{ \pmb{ \mathfrak{ Volume_{(Cylinder)} = \pi r^2h}}}}}} \\ \\ [/tex]

Substituting the required values:

[tex] \\ \: \: \dashrightarrow \sf \: \: Volume = 3.14 \times {(2)}^{2} \times 7 \\ \\ [/tex]

[tex]\: \: \dashrightarrow \sf \: \: Volume = 3.14 \times 4 \times 7 \\ \\ [/tex]
