Michael drinks 355 milliliters of orange juice and puts 6 centiliters of syrup on his pancakes for breakfast. How many milliliters of liquid did he consume?
Answer:
415 milliliters
Step-by-step explanation:
Given,
The quantity of orange juice she consumes = 355 milliliters,
And, the quantity of syrup she consumes = 6 centiliters,
Since, 1 centiliters = 10 milliliters
⇒ The quantity of syrup she consumes = (10×6) milliliters = 60 milliliters
Thus, the total liquid she consumed = The quantity of orange juice she consumes + the quantity of syrup she consumes
= 355 + 60
= 415 milliliters
Marvin is trying to finish 1/2 of his test every 2/3 hour. How many hours will it take Marvin to complete his whole test
It will take Marvin 4/3 hours to complete his entire test.
Time taken to complete 1/2 of test = 2/3 hours
The total fraction of the test can be represented as 1
Therefore,
If 1/2 of test = 2/3 hours
1 of test = x
We can solve for x using cross multiplication :
1/2x = 2/3
Multiply both sides by 2 to isolate x
(1/2x × 2) = (2/3 × 2)
x = 4/3 hours
The number of hours it will take to complete the whole test is 4/3 hours

Theo needs to measure 3/4 cups of water. He has a 1/8 cup measuring cup. How many 1/8 cups are in 3/4 cup?
The number of 1/8 cups in 3/4 cup is given by the equation A = 6 cups
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of cups be represented as A
Now , the equation will be
The amount of the bigger cup = 3/4
The size of the measuring cup = 1/8
So , the number of cups A = amount of the bigger cup / size of the measuring cup
Substituting the values in the equation , we get
The number of cups A = ( 3/4 ) / ( 1/8 )
On simplifying the equation , we get
The number of cups A = ( 3/4 ) x 8
The number of cups A = 3 x 2
The number of cups A = 6 cups
Therefore , the value of A is 6 cups
Hence , the number of cups is 6 cups

There are 21 students in one class and 19 in another. The lab has 34 computers. How many students will need to share a computer when both classes are in the lab at the same time ?
A total of 6 students from the combined classes of 21 and 19 students will need to share computers in a lab with 34 computers available.
The question involves determining how many students will need to share a computer when both classes with 21 and 19 students, respectively, are in a computer lab with 34 computers at the same time. To solve this, you can add the number of students in both classes to get the total number of students, and then subtract the number of available computers to find out how many students will need to share.
Adding the two classes together, 21 + 19, we get a total of 40 students. Since there are 34 computers, we subtract this from the total number of students: 40 - 34 equals 6. Therefore, 6 students will need to share a computer.

Alina spent no more than $45 on gas for a road trip. The first gas station she used charged $3.50 per gallon and the second gas station charged $4.00 per gallon. Which inequality relates the number of gallons of gas she bought at the first station, x, the number of gallons of gas she bought at the second station, y, and the total amount she paid? What are the possible values of y? 3.5x + 4y ≥ 45, y ≥ 11.25 3.5x + 4y ≥ 45, 0 ≤ y ≤ 10.375 3.5x + 4y ≤ 45, 0 ≤ y ≤ 11.25 3.5x + 4y ≤ 45, y ≥ 10.375
Answer:
The correct option is 3.
Step-by-step explanation:
Let the number of gallons of gas she bought at the first station be x and the number of gallons of gas she bought at the second station be y.
It is given that the first gas station she used charged $3.50 per gallon and the second gas station charged $4.00 per gallon.
Total cost is defied as
[tex]T=3.50x+4.00y[/tex]
Alina spent no more than $45 on gas for a road trip.
[tex]T\leq 45[/tex]
[tex]3.50x+4.00y\leq 45[/tex] .... (1)
If she bought all number of gallons from the second station, then
[tex]4y\leq 45[/tex]
Divide both sides be 4.
[tex]y\leq 11.25[/tex]
Number of gallon can not negative.
[tex]0\leq y\leq 11.25[/tex] .... (2)
Inequality (1) relates the number of gallons of gas and inequality (2) represent all the possible values of x.
Therefore, the correct option is 3.
Answer:
3.5x + 4y ≤ 45, 0 ≤ y ≤ 11.25 (c)
If h(x) = −2x − 10, find h(−4). −2 −18 −3 −16
Answer:
The correct option is (a) i.e.
h(-4) = -2
Step-by-step explanation:
The mathematical expression is given as :
[tex]h(x)=-2x-10[/tex]......(1)
Where
h(x) is dependent on x
We need to find the value of h(x) at x = -4 . Putting the value of x in equation (1) we get :
[tex]h(-4)=-2(-4)-10[/tex]
[tex]h(-4)=8-10[/tex]
h(-4) = -2
The value of h(-4) is -2. So, the correct option is (a). Hence, this is the required solution.
what is 2 1/2 divided by 1/3
The value of the 2¹/₂ divided by 1/3 is equal to 15/2, or 7¹/₂
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
So, we can rewrite the expression as:
2¹/₃ ÷ 1/3 = (5/2) ÷ (1/3)
Now, we multiply the first fraction by the reciprocal of the second fraction:
(5/2) ÷ (1/3) = (5/2) × (3/1)
Multiplying the numerators and denominators, we get:
(5 × 3) ÷ (2 × 1) = 15/2
Therefore, 2¹/₂ divided by 1/3 is equal to 15/2, or 7¹/₂.

The price of a pair of pants is $29.95 and the sales tax is 5%.
What is the total cost of the pair of pants?
Please help me I NEED HELP BAD
To find the total cost of a pair of pants priced at $29.95 with a 5% sales tax, calculate $29.95 multiplied by 0.05 for the tax amount, add that to the original price, and the total cost including tax is $31.45.
To calculate the total cost of a pair of pants with a sales tax, you first need to determine the amount of tax to be added to the price. Here's how you can do it:
Convert the sales tax rate from a percent to a decimal by dividing by 100. For a 5% sales tax, you get 0.05.
Multiply the price of the item by the decimal sales tax rate to find the amount of sales tax. So, $29.95 imes 0.05 = $1.4975.
Round the sales tax to the nearest cent, giving us $1.50.
Add the sales tax to the original price of the item. Therefore, $29.95 + $1.50 = $31.45, which is the total cost with tax.
