Please I Need Help. Find The Measure Of The Angle DCB In The Rhombus ABCD.

Answers

Answer 1

Answer:

53

Step-by-step explanation:

its the same to DAB because it is in the opposite side to the DAB

Answer 2

Answer:

Step-by-step explanation:

In Rhombus, diagonals are angle bisectors.

So, ∠DAC = ∠CAB

∠A = ∠DAC+∠CAB

    = 53 + 53

∠A = 106

In Rhombus, opposite angles are equal.

∠DCB = ∠A

∠DCB = 106°

y=-9/2x-10

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-8)/(-2-(-4))

m=-9/(-2+4)

m=-9/2

y-y1=m(x-x1)

y-8=-9/2(x-(-4))

y-8=-9/2(x+4)

y=-9/2x-36/2+8

y=-9/2x-18+8

y=2(x - 1)

Step-by-step explanation:

y=2 x -2

swap sides so that all variable terms are on the left hand side

2x - 2 =y

add 2 to both sides

2x = + 2

Divide both sides by 2.

2 x = y + 2

Dividing by 2 undoes the multiplication by 2.

x = y + 2

Neil has 2 pounds of grapes. He uses some to make a fruit salad. Now Neil has 8 ounces of grapes. How many ounces of grapes does Neil use for the fruit salad?

Answers

Answer:

Neil uses 24 ounces of grapes for the fruit salad.

Step-by-step explanation:

Quantity of grapes = 2 pounds

Use 1 pound = 16 ounces

So,

Quantity of grapes = 2(16) = 32 ounces

Neil uses some grapes to make a fruit salad. Now Neil has 8 ounces of grapes.

Quantity of grapes that Neil use for the fruit salad = [tex]32-8=24[/tex] ounces

Therefore,

Neil uses 24 ounces of grapes for the fruit salad.

On which number line do the points represent negative seven and one over two and +1? (4 points)

Answers

Answer:

A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers.
