Answer:15 meters higher

Step-by-step explanation: 30-30+15

15 meters higher from the start of the ride are they after these 20 seconds.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Let's say they were initially at level x from ground

After the first 20 seconds.

Level = x + 30

Then plunges down

So,

Level = x + 30 - 30 = x level.

Now 15-meter rise

So,

Level = x + 15

Now level from initial = (x + 15) - x = 15 meter.

Hence "15 meters higher from the start of the ride are they after these 20 seconds".

Given:

Gracie is sharing 75 marshminnows among 4 of her friends.

Each of her friends gets  the same number of marshminnows, and she gives them as many marshminnows as possible.

To find:

The remaining number of marshminnows she has.

Solution:

We have,

Total number of marshminnows = 75

Number of friends = 4

Divide 75 by 4.

[tex]4|\overline{75}|{18}\\ -4\\\text{\quad }\overline {35} \\ -32\\\text{\quad }\overline {\ 3\qaud }[/tex]

Here, quotient is 18 and remainder is 3. It means, each friend can be get maximum 18 marshminnows and the number of remaining marshminnows is 3.

Therefore, the correct option is B.

Answer:

-2 ≤x ≤10

Step-by-step explanation:

the domain refers to the x

the x is in between -2 and 10

Answer:

no

Step-by-step explanation:

because she just has one less so all she need to do is get one more and then she'd have enough

Answer:

yes, she has enough ribbon.

Step-by-step explanation:

find common denominator for 2 2/3 and 2 3/4 which is 12

2 2/3 becomes 2 8/12 [what she needs]

2 3/4 becomes 2 9/12 [what she has]

she has 1/12 more than she needs.

Answer:

16. Adults = $12

17. 750 ml

18. $9

19. 96 students

20. 5/6x

Step-by-step explanation:

16.

A child pays = $9

Bus fee = 1/3 of $9

= 1/3× 9

= $3

Admission fee for a child= amount paid - bus fee

= $9 - $3

= $6

What was the admission fee for adults, if children get in for haprice

Children = 1/2 of adults

$6 = 1/2 × adults

Adults = 6÷ 1/2

= $12

Adults = $12

17.

Leaking rate = 10 ml per minutes

One and quarter of an hour

1 hour = 60 minutes

Quarter of an hour = 15 minutes

Total time = 75 minutes

Air lost in 75 minutes = 10 ml × 75

= 750 ml

18. 4 glasses for $3

1 dozen of glasses = 12

12 glasses = $x

4 = 3

12 = x

Cross product

4*x = 3*12

4x = 36

x = 36 / 4

= 9

x = $9

19.

Total students = x

1/2x = soccer

Rugby = 1/2 of 1/2x

= 1/2 * 1/2x

= 1/4x

24 = 1/4x

x = 24÷1/4

= 24 × 4/1

x = 96 students

20.

Total petrol = x

Petrol in the tank = 1/2x

Petrol used = 1/3 of 1/2x

= 1/3 × 1/2x

= 1/6x

Petrol remaining after the trip = x - 1/6x

= 6x-x/6

= 5/6x

Answer:

D is the correct choice

Step-by-step explanation:

To get the y-intercept, we write the equation in the standard form

The standard form is ;

y = mx + b

So we have to rewrite the equation this very form

Thus, we have that;

0.05y = 0.4x + 1.25

we simply isolate the y value

To do this, we divide through by 0.05 and the y-intercept value will be ;

1.25/0.05 = 25

Answer:

constants

Step-by-step explanation:

Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.

Answer:

175.84 m

Step-by-step explanation:

Given that:

A circular garden which has a radius of 28 m.

[tex]\pi[/tex] = 3.14

To find:

The fencing required to enclose the circular garden ?

Solution:

Here, we are given a circle and its radius.

We are required to find the perimeter of the circle in order to find the fencing required to enclose the circular garden..

Formula for finding the perimeter of a circle is:

Perimeter = [tex]2\pi r[/tex]

where [tex]r[/tex] is the radius of the circle.

Using the given values in the formula:

Perimeter = [tex]2\times 3.14 \times 28[/tex] = 175.84 m

Therefore, 175.84 m of fencing is required.

Answer:

No the soultion is not equal to 1 1/4

The solution to the given question is either 6 3/4 or  4 /27

Step-by-step explanation:

Let

3(+9)=(4−7+7)x

27 = 4x

x= 27/4

x= 6 3/4  is the answer

or

Let

3(+9) x=(4−7+7)

27x = 4

x= 4/27

The plus sign inside the bracket indicates that 3 is multiplied with positive nine and -7 and +7 are cancelled and 4 is left behind.

If x is on the left side the answer will be 6 3/4  and if it is on the right side the answer is 4/27 .

In both cases the answer is not equal to 5/4 .

5/4 means 1 1/4 which is not equal to either 6 3/4 or 4/27

Answer: The five exponent properties are

Product of Powers: When you are multiplying like terms with exponents, use the product of powers rule as a shortcut to finding the answer. It states that when you are multiplying two terms that have the same base, just add their exponents to find your answer.

Power to a Power: When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. ... Then multiply the two expressions together. You get to see multiplying exponents (raising a power to a power) and adding exponents (multiplying same bases).

Quotient of Powers: When you are dividing like terms with exponents, use the Quotient of Powers Rule to simplify the problem. This rule states that when you are dividing terms that have the same base, just subtract their exponents to find your answer. The key is to only subtract those exponents whose bases are the same.

Power of a Product: The Power of a Product rule is another way to simplify exponents. When you have a number or variable raised to a power, it is called the base, while the superscript number, or the number after the '^' mark, is called the exponent or power.

Power of a Quotient: The Power of a Quotient rule is another way you can simplify an algebraic expression with exponents. When you have a number or variable raised to a power, the number (or variable) is called the base, while the superscript number is called the exponent or power

You can use these any way you want to rewrite an equation.

have this same question -_-

Answer:

18

Step-by-step explanation:

Note that 75% = 75/100 = 3/4, so 3/4 of the marbles must be blue. Let x be amount of blue marbles added. We can write an equation using this.

75% = 3/4 = (3 + x blue marbles)/(3 + 4 + 3 + x total marbles) = (3+x)/(10+x)

Multiplying by 4(10 + x) on both sides:

3(10 + x) = 4(3+x)

30 + 3x = 12 + 4x

18 = x

Therefore, we must add 18 blue marbles for 75% of the marbles to be blue.
