3 tacos cost 18 dollars. Complete the table to show the cost of 4, 5, and 6 tacos at the same rate.

Now I figured out the cost of each taco, but I need help completing the table.

Answers

Answer:

The rate is 6 for all of them

Step-by-step explanation:

The rate would be the price for one taco, so you divide the cost by the number of tacos you're getting.

Answers: Well 1 taco is 6$. 4 tacos is 24$. 5 tacos is 30$. 6 tacos is 36$.

Substitution 8th grade math homwork. 1 question
First person to get it answer gets reward

Answers

Answer: (5, 11)

Step-by-step explanation:

y = 2x + 1

x + y = 16

Substitute 2x + 1 for y in 'x + y = 16'

x + y = 16

x + (2x + 1) = 16

3x + 1 = 16

Subtract both sides by 1

3x = 15

Divide both sides by 3

x = 5

Now to find y

Since we know what x is, we can use one of the equations and substitute 5 for x. I'll use both to show that you get the same answer.

Second equation:

x + y = 16

5 + y = 16

Subtract both sides by 5

y = 11

First equation:

y = 2x + 1

y = 2(5) + 1

y = 10 + 1

y = 11

The solution would be (5, 11)

Answer:

(5, 11) point form

Answer:The nail would be at the same height since trees grow at their tops.

Step-by-step explanation:

Answer:

speed of growth of tree = 5cm/year

Years after John Came = 10 years

c) The rock's maximum height is 50 feet.

d) It takes 6 seconds for the rock to land on the ground.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, f(x_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]f(x_{v})[/tex]

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]\bigtriangleup = b^{2} - 4ac[/tex]

In this question:

The height of the ball after t seconds, in feet, is given by:

[tex]h(t) = -2t^2 + 4t + 48[/tex]

Which is a quadratic equation with [tex]a = -2, b = 4, c = 48[/tex]

a) What is the initial height?

This is [tex]h(0) = 48[/tex]. So the initial height of the rock is of 48 feet.

b) How many seconds does it take to reach the maximum height?

This is the value of t at the vertex. So

[tex]t_{v} = -\frac{b}{2a} = -\frac{4}{2(-2)} = 1[/tex]

It takes 1 seconds for the rock to reach maximum height.

c) What is the rock's maximum height?

This is the height of the ball after 1 second. So

[tex]h(1) = -2(1)^2 + 4(1) + 48 = 50[/tex]

The rock's maximum height is 50 feet.

d) How many seconds does it take to for the rock to land on the ground?

This is t for which [tex]h(t) = 0[/tex], so we solve the quadratic equation.

[tex]\bigtriangleup = (4)^2-4(-2)(48) = 400[/tex]

[tex]t_{1} = \frac{-4 + \sqrt{400}}{2*(-2)} = -4[/tex]

[tex]t_{2} = \frac{-4 - \sqrt{400}}{2*(-2)} = 6[/tex]

Time is a positive measures, so it takes 6 seconds for the rock to land on the ground.

In the diagram below, ZGRS - ZART, GR = 36, SR = 45, AR = 15, and RT = 18. G 36 А 15 R S T 45 18 Which triangle similarity statement is correct? A AGRS ~AART by AA B AGRS ~AART by SAS C AGRS - AART by SSS D) AGRS is not similar to A ART.

Answers

Answer: the answer is D

The triangle GRS is not similar to the triangle ART because the ratio of the corresponding sides is not in the same proportion option (D) is correct.

What is the similarity law for triangles?

It is defined as the law to prove that the two triangles have the same shape but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same propertions and the corresponding angles are congruent.

We have two triangles:

ΔGRS and ΔART in which:

GR = 36 units, SR = 45 units, AR = 15 units, and RT = 18 units

To check the similarity take the ratio of the corresponding sides.

[tex]\frac{36}{15} =\frac{45}{18}[/tex] (after simplification)

[tex]\frac{12}{5} \neq \frac{15}{6}[/tex]

As we can see the ratio of the corresponding sides is not in the same proportion.

Thus, the triangle GRS is not similar to the triangle ART because the ratio of the corresponding sides is not in the same proportion option (D) is correct.

A store owner purchased 70 soccer balls for $24.50 each. The store owne sold 40 of the soccer balls for $39.75 each. The remainder of the soccer balls were sold for $29.50 each. How much profit did the store owner earn?

Answers

Answer:

The stores profit was $757

Step-by-step explanation:

70 x 24.50=1715

they spent 1715 on 70 soccer balls.

They sold 40 of the soccer balls for 39.75 each.

so 40 x 39.75=1590

Then the the remainder of the soccer balls would be 30 since they only started with 70

so they sold 30 soccer balls for 29.50 each.

30 x 29.50= 882

So add 882+1590=2472

then take that number and subtract it from 1715

2472-1715=757 So in profit they made $757 dollars.
