Chris wants to order DVD’s over the internet.Each dvd cost $15.99 and shipping the entire order costs $9.99.If he can spend no more than $100,how many DVD’s could he buy (please so all work)

Answers

Answer: There are 3 DVD s that can be bought with under $100.

Step-by-step explanation:

Since we have given that

Cost of DVD = $15.99

Cost of Shipping = $ 9.99

Total cost per DVD would be

$15.99 + $9.99 = $ 25.98

Amount he has to spend no more than $ 100.

So, number of DVDs would be

100 ÷ 25.98 = 3.84

Hence, there are 3 DVD s that can be bought with under $100.

Chris can order 3 DVDs over the internet, if he spent $100.    

Given here,  

Cost of DVD = $15.99  

Shipping Cost = $ 9.99

Amount spend = $ 100.

Total cost per DVD,  

$15.99 + $9.99 = $ 25.98

 

So, number of DVDs would be buy,  

100 ÷ 25.98 = 3.84

Therefore, Chris can order 3 DVDs over the internet, if he spent $100.

What is a Triangle?

A triangle is a polygon with three sides, angles and vertices.

The triangle is classified into various types on the basis of the angle and on the basis of the equality of the length of the sides, as obtuse , acute and right angled triangle and scalene, isosceles and equilateral triangle.

A polygon is called regular if it has all sides equal.

The figure shows a triangle.

The two sides of the triangle are 5-2x and -4x+9

When all the sides of the triangle is equal, it is called an equilateral triangle.

5-2x = -4x +9

Taking the like terms on one side,

-2x +4x = 9 -5

2x = 4

x = 2

The measure of each side is,

5 - 2*2 = 1

-4x +9 = -4 * 2 +9 = 1

The side length is 1 unit.

The perimeter of a triangle is the sum of all sides, as all the sides are equal, the perimeter is equal to 3 * side.

Naomi is two-thirds as tall as her father. If Naomi is 54 inches tall, how tall is her father?

Answers

54/2*3
=27*3
=81
answer is 81 inches

Answer:

Naomi's father is 81 inches tall.

Step-by-step explanation:

Naomi is two-thirds as tall as her father.

Let "x" be the Naomi's father height.

Naomi is 54 inches tall.

[tex]\frac{2}{3}.x = 54[/tex]

We need to solve for x.

To solve for x, multiply both sides by the reciprocal of [tex]\frac{2}{3}[/tex].

The reciprocal of [tex]\frac{2}{3}[/tex] is [tex]\frac{3}{2}[/tex].

[tex]\frac{3}{2} . \frac{2}{3} . x = 54.\frac{3}{2}[/tex]

x = [tex]54.\frac{3}{2}[/tex]

x = 27.3

x = 81

So, Naomi's father is 81 inches tall.

in order for Brady to earn a b in his biology course, his test scores must average at 80%. ON the first 5 tests, he has an average of 77%. There is one test remaining in the course. What is the minimum score Brady needs to earn on the last test to receive a b in the class?

Answers

In order for him to have a 77% on his first 5 tests, that means the total amount of points earned on those 5 tests was 385 points out of 500 points.
(77*5 out of 5*100 points)
So if we want to add a test and have a 80% average this is what we have to do:
(385+x)/6 = 80 (multiply by 6 on both sides)
385 + x = 480 (minus 385 on both sides)
x = 95

Answer:

Brady needs to earn a 95% on the final test

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Before we can actually solve this we need to create a formula that calculates the grade of the last test in order to get an average of 80%. Since he got a 77% average for his first 5 tests, we can multiply 0.77 by 5, add the final test and then divide by the total amount of tests taken. Like so,

[tex]0.80 = \frac{(0.77*5)+x}{6}[/tex]

[tex]0.80 = \frac{3.85+x}{6}[/tex] .... multiply both sides by 6

[tex]4.8 = 3.85+x[/tex] ... subtract both sides by 3.85

[tex]0.95 = x[/tex]

Finally, we can see that Brady needs to earn a 95% on the final test in order to increase his overall average to 80%.

The minimum height for riding on the Super Screaming Spinner at the theme park is 52 inches. Which of the following expressions shows the height to ride?

A. h < 52
B. h ≤ 52
C. h > 52
D. h ≥ 52

Answers

Answer:

D )Expression for height to ride is h ≥ 52

Step-by-step explanation:

Given : The minimum height for riding on the Super Screaming Spinner at the theme park is 52 inches.

To find : Which of the following expressions shows the height to ride.

Solution : We have given that

Minimum height of spinner = 52 inches.

It state that  height of spinner for riding at least  52 it mean it must be 52 or greater than 52

Therefore, D )Expression for height to ride is h ≥ 52

Answer:  Option 'D' is correct.

Step-by-step explanation:

Since we have given that

The minimum height for riding on the Super Screaming Spinner at the theme park is 52 inches.

So, Let the height to ride be 'h'.

We have mentioned that value of h is must be greater than or equal to 52 inches.

So, it becomes,

[tex]h\geq 52\ inches[/tex]

Hence, Option 'D' is correct.

What is the value of p? 3+17p=−32−11p

Answers

3+17p=−32−11p
17p + 11p = -32 - 3
28p = -35
    p = -35/28
    p = -5/4
or 
    p = -1 1/4

The value of p in this equation 3 + 17p = -32 - 11p is -5/4. To find the value of p, we need to solve the equation: 3 + 17p = -32 - 11p

First, let's gather all the terms involving p on one side of the equation:

17p + 11p = -32 - 3

Now, combine the p terms:

28p = -35

Now, isolate p by dividing both sides of the equation by 28:

p = -35 / 28

To simplify the fraction, we can divide both the numerator and denominator by the greatest common divisor (GCD) of 35 and 28, which is 7: p = -5/4

So, the value of p is -5/4.

When Mr. J. Raff took his two children to the zoo, their tickets cost $8.75. The next family in line was Mrs. Ella Fant with Grandpa and the five Fant kids. Their tickets cost a total of $19.75. How much does the zoo charge for each adult and for each child?

Answers

A + 2K = 8.75
2A + 5K = 19.75
Change the first expression so that we can subtract the As
2A + 5K = 19.75
2A+4K= 17.50
If the signs are the same, subtract one expression from another
K= 2.25
substitute K into any expression to get A
A+4.50= 8.75
Subtract 4.50
a=4.25


K=$2.50
A= $4.25


Final answer:

The zoo charges approximately $4.42 for each adult and $0.92 for each child.

Explanation:

To determine the cost of an adult ticket, we can subtract the cost of the children's ticket from the total cost. Let's set up a system of equations using variables for the cost of an adult ticket (a) and the cost of a child ticket (c):

a + 2c = 8.75

a + 5c = 19.75

Multiplying the first equation by 5 and subtracting the second equation from it, we get:

5a + 10c - a - 5c = 43.75 - 19.75

4a + 5c = 24

Now we can solve this system of equations to find the values of 'a' and 'c'.

Multiplying the first equation by 4 and subtracting the second equation from it, we get:

4a + 8c - 4a - 20c = 35 - 24

-12c = -11

c = -11 / -12

c = 11 / 12

Substituting the value of 'c' back into the first equation, we get:

a + 2 * (11 / 12) = 8.75

a + 11 / 6 = 8.75

a = 8.75 - 11 / 6

a = 53 / 12

So, the zoo charges approximately $4.42 for each adult and $0.92 for each child.

The explanation provides a step-by-step process to determine the minimum trips required for the miners to cross the river.

To determine the minimum number of trips required for the miners to cross the river, we need to carefully consider the constraints given.

First, A and B can cross together because the maximum combined weight of their cargoes is 90 kg (40 + 50) which is less than 100 kg.

Then, A returns alone, carrying B's cargo, leaving B and C on the other side. B and C cross together as the combined weight of their cargoes is 40 kg (20 + 20) which is less than 100 kg.

Finally, B returns and takes A's cargo, crossing with C's cargo. In total, the minimum number of trips needed is 9 (Option A).
