Answer:

55, 125 and 125

Step-by-step explanation:

In this question, we are asked to find the other 3 angles in an intersection.

Please check attachment for what the diagram of the intersection might look like.

The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.

since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]

These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.

The area of a trapezoid is 864 cm2. It has a height of 24 cm, and the length
Darina [25.2K]

Answer:

Length of other base = 42 cm

Step-by-step explanation:

h = 24 cm

One of its base a = 30 cm

Area=864cm^{2}\\\\\frac{(a+b)*h}{2}=864\\\\\frac{(30+b)*24}{2}=864\\\\(30+b)*12=864\\\\30+b=\frac{864}{12}\\\\30+b=72

b = 72 - 30

b = 42 cm

Is x+1/2=x-1/2 true?
Sedaia [141]

\frac{x+1}{2}=\frac{x-1}{2} is not true

Step-by-step explanation:

We need to find if \frac{x+1}{2}=\frac{x-1}{2} is true?

Solving:

\frac{x+1}{2}=\frac{x-1}{2}

Cross Multiplying

2(x+1)=2(x-1)

2x+2=2x-2

2x-2x=-2-2

0=-4

Since both sides of the equation are not equal, so there is no solution.

So, \frac{x+1}{2}=\frac{x-1}{2} is not true.

Maxwell’s vegetarian tacos require 34 tablespoons of chili powder for every 12 pounds of vegetables. How much chili powder will
Crazy boy [7]

Answer:

2 1/4

How?

Set up a proportion. The proportion will be teaspoons of chili powder over pound of vegetables.

Because of the above, the first proportion will be:

x is 3/4 and y is 1/2. Across from that proportion make another one

x is "n" because you're trying to figure out how much chili powder you need. y is 1 3/4.

Multiply 3/4 and 1 3/4, which is 9/16. Then, divide 9/16 and 1/2, which is 9/8. Simplify it to 1 1/8, and Maxwell will need 1 1/8 teaspoons of chili powder.
