Skye's Ice Cream Shoppe is Mario's favorite place to get ice cream. Unfortunately, because he was late arriving, his friends had already ordered. He did not know what they had ordered for him. They told him that is was either a waffle cone or a sundae and that the ice cream flavor was apricot, chocolate, or blackberry.

What is the probability he will get a sundae?


A.25%

B. 85%

C. 50%

D.90%

Answers

Answer:

C. 50%

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

They told him that is was either a waffle cone or a sundae

Two options, one of which is a sundae

So 1/2 = 0.5 = 50% probability he will get a sundae, and the answer is given by option C

A consistent, dependent system of equations is a system with __________. (1 point)

only one line
intersecting lines that have different slopes and different y-intercepts
intersecting lines that have the same slope but different y-intercepts
intersecting lines that have the same slope and the same y-intercept

Answers

Answer:

Option A. Intersecting lines that have different slopes and different y-intercepts.

Step-by-step explanation:

we know that

A system of two linear equations can have one solution, an infinite number of solutions, or no solution.

If a system has at least one solution, it is said to be consistent

If a consistent system has exactly one solution, it is independent

If we have intersecting lines that have different slopes and different y-intercepts

then

will have one solution

therefore

The system will be consistent independent

Answer:

hope this helps

Explain why the two figures below are not similar. Use complete sentences and provide evidence to support your explanation. PLSS HELPP ASAP

Answers

Answer/Step-by-step explanation:

The corresponding segments of two similar figures are always proportional to each other. I'm other words, the ratio of their corresponding segments are equal.

The figures shown above in this question are not similar figures because their segments are not proportional to each other.

This is because:

DE/KL ≠ FG/MN

DE = 2 units

KL = 1 unit

FG = 1 unit

MN = 1 unit

DE/KL = 2/1 = 2

FG/MN = 1/1 = 1

Thus, DE/KL ≠ FG/MN.

Therefore, the figures are not similar.

which value of a makes the following equation true
(x+a)^2=x^2+16x+64

Answers

Answer:

The value of a is 8.

Step-by-step explanation:

In the expression, x² + 16x + 64, 64 is a perfect square of 8 so if you factorize it, you will get :

x² + 16x + 64

= x² + 8x + 8x + 64

= x(x + 8) + 8(x + 8)

= (x + 8)²

(x + a)² = (x + 8)²

a = 8

Our hero, Captain Gravity, is being pulled into a black hole at an acceleration of 20mi/h^2, where x is the distance between his ship and the black hole in miles. Right now he is 300 miles away, but he was not paying attention to his instruments, so he is already moving toward the black hole at 100mi/h. His thrusters give him a constant acceleration of 30mi/h^2 in any direction. Evaluate the following as true or false. Captain Gravity will get sucked into the black hole.

a. True
b. False

Answers

Answer:

False

Step-by-step explanation:

Captain Gravity pulls towards the black hole, if his thruster is pointed towards the black hole than the speed will accelerate. In this case the speed will decelerate below from 20 mi/h to 10m/hr. This will reduce the speed and there will be at least 3 hours to stop the movement towards black hole.

Find the value of X

Answers

Answer:

180 = (7x +5)+(3x -5 ) + 90

180 = 10x +90

10x = 90

x= 9

The required value of variable "x" is 9 which is determined by the property of the interior angles of the triangle.

What is a Triangle?

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbol Δ.

The triangle is given in the question which has :

(3x - 5) and (7x + 5)

We know that the sum of all interior angles of the triangle is always 180 degrees.

As per the property of interior angles,

⇒ 180 = (7x +5)+(3x -5 ) + 90

Rearrange the terms of  variable "x" and combine them,

⇒ 180 = 10x +90

⇒ 10x  = 180 - 90

⇒ 10x = 90

⇒ x = 90/10

⇒ x = 9

Therefore, the required value of variable "x" is 9.

Noah and Lin both solved the equation 14a-2(a-3). Do you agree with either of them?​

Answers

Answer= yes because we are solving for a and 3 divided 1/3=6

Step-by-step explanation:

Substituting a=-12 into the original equation yields a true statement, so their solutions are correct.

Answers vary. There are at least two solution paths to this equation: you can divide each side by 5 first, then collect like terms, or you can distribute and collect like terms, then continue to solve.

Answers vary. There are still two solution paths to this equation, but one is much simpler than the other. Since not all the terms are multiples of 4, dividing first by 4 will give a fractional coefficient of x on one side. Therefore, distributing first and then collecting like terms and solving is the simpler solution path.
