1. ∠C ≅ ∠B  by definition of congruency

2. m∠Y by definition of obtuse angle

3. ∠C ≅ ∠A by definition of congruency

Answer:

2/3

Step-by-step explanation:

I think you meant y=2/3x+4 because what you wrote is not the right way to right that equation, but anyways the slope of the parallel line is 2/3 because lines that are parallel have the same slope.

I hope this helps!

Answer:

-63

Step-by-step explanation:

Answer:54 = t + 9

Step-by-step explanation:

Answer:

h(2) = 8

Step-by-step explanation:

We are told that the function h(x)= -x² + 6x Models the path of water in a fountain in meters

Since the function is h(x)= -x² + 6x.

It means h(2) will be;

h(2) = -(2²) + 6(2)

h(2) = -4 + 12

h(2) = 8

Answer:

O weight in kilograms = 25 x 3.5 ÷ 2.2

Step-by-step explanation:

As a butcher, you sell beef in 3.5-pound packages. You anticipate needing 25 packages for the next two days.

Therefore, the total number of pounds for the 25 packages =

3.5 pound packages × 25

= 87.5 pounds

We are told that : The wholesaler from whom you purchase large pieces of meat measures the weight of the beef in kilograms.

Note that:

2.2 pounds = 1 kg

Hence:

87.5 pounds =

= 87.5÷ 2.2

= 39.772727273 kg

He needs to buy 39.772727273kg from the wholesaler

The equation can you use to determine the weight of the beef, in kilograms, that you need to purchase from the wholesaler is:

O weight in kilograms = (25 x 3.5) ÷ 2.2

Answer:

This is true

Step-by-step explanation:

28 = 28 is what you will get if you put N into the equation.

Answer:

Your answer is: 28 = 28

The left side  28  is equal to the right side  28 , which means that the given statement is always true.

You have to plug in both n's with a 6, so your equation would be ↓ 4(2(6)-5)=3(6)+10

Answer:

Correct choice: C. [tex]x=\pm\sqrt{10}\mathbf{i}[/tex]

Step-by-step explanation:

The quadratic equation to solve is:

[tex]x^2+10=0[/tex]

Since this equation is incomplete, we can solve it without using the quadratic solver formula.

Subtracting 10:

[tex]x^2=-10[/tex]

Taking square root:

[tex]x=\pm\sqrt{-10}[/tex]

Recall the square root of a negative number leads to imaginary solutions where the Unit Imaginary Number (i) is used, where:

[tex]\mathbf{i}=\sqrt{-1}[/tex]

The solutions to the equation are:

[tex]x=\pm\sqrt{10}\mathbf{i}[/tex]

Correct choice: C. [tex]x=\pm\sqrt{10}\mathbf{i}[/tex]

Answer:

3/10 of the renaming full pizza has pepperoni

Step-by-step explanation:

Here, we want to calculate how much of the remaining pizza had pepperoni.

From the question, 1/2 has pepperoni and 1/2 is plain without pepperoni

she eats 1/5 of the pizza having pepperoni, this means that she is actually left with some parts is the half having pepperoni

The actual of the half remaining with pepperoni will be 1/2 - 1/5 = 3/10

This means that 3/10 of the remaining full pizza has pepperoni

Answer:

25

Step-by-step explanation:

23+24+25=72

hope i helped!! :)

( if it is right, pls mark brainliest!!)

Answer:

25

Step-by-step explanation:

let x represent the first consecutive number.

let x+1 represent the second consecutive number.

let x+2 represent the third consecutive number.

x + x+1 + x+2 = 72

3x + 3 = 72

3x = 72 - 3

3x = 69

3x/3 = 69/3

x= 23

first number= x = 23

second number = x+1

= 23+1

=24

third number= x+2

=23+2

=25

the largest of these numbers is 25

Answer: The slope is [tex]\frac{1}{2}[/tex].

Step-by-step explanation:

1. You set up your Slope Formula [tex]M=\frac{y2-y1}{x2-x1}[/tex].

2. Substitue your points into the formula.[tex]M=\frac{1--1}{6-2}[/tex].

3. Once you substitute, you will solve the equation[tex]M=\frac{2}{4}[/tex].

4. Simplify the equation if you have to [tex]M=\frac{1}{2\\}[/tex].

Solve for  x  by simplifying both sides of the equation, then isolating the variable.

Answer:

a) vertical angles

b) same side interior angles

c)alternate interior angles

Step-by-step explanation:

vertical angles are angles that are across from each other and they are congruent

interior angles are angles that are in between the parallel lines and when they are on the same side it means that they are on the same side of the transversal

interior angles are angles that are in between the parallel lines and when they are on different sides it means that they are on opposite sides of a transversal, this is called alternate interior angles

Answer:

Mass of bread crumb is 20 times the mass of the ant..

Step-by-step explanation:

Mass of an ant = [tex]4\times 10^{-6}[/tex] kg

Ant carries a weight of bread crumb to its anthill.

Mass of the bread crumb = [tex]8\times 10^{-5}[/tex] kg

Ratio of their masses,

[tex]\frac{\text{Mass of the ant}}{\text{Mass of bread crumb}}=\frac{4\times 10^{-6}}{8\times 10^{-5}}[/tex]

[tex]\frac{\text{Mass of the ant}}{\text{Mass of bread crumb}}=\frac{1}{2\times 10^{(-5+6)}}[/tex]

[tex]\frac{\text{Mass of the ant}}{\text{Mass of bread crumb}}=\frac{1}{20}[/tex]

Mass of the bread crumb = 20×(Mass of the ant)

Therefore, mass of the bread crumb is 20 times the mass of the ant.

Answer:

75 ounces

Step-by-step explanation:

39/13=3  so each candy bar weighs 3 ounces each so 25*3=75

Answer:

75 ounces

Step-by-step explanation:

39 divided by the amount of candy bars (13) is 3. Which means each candy bar weighs 3 ounces. So 3 times 25 is 75.

Umm...... Okay then..?
