Write an equation to represent "33 is 15 less than k."

Answers

Answer: k - 15 = 33

Step-by-step explanation:

So basically you just translate the problem into math form. 33 is a #, is is an = sign so, 33 = so far. Then 15 is less than k, which is not 15 - k but k - 15. There's a difference. Say k is 30, so 30 - 15 and not 15 - 30. So then you have 33 = k - 15, then I just switched it around to look better and done.

k-15=33

Adrien has 4 liters of milk. He drinks y liters each day.

a) If Adrien has x liters of milk left after one week, express x in terms of y.

b) State the independent and dependent variables in the question

Answers

Answer:

A) X = 4 - 7Y

B) Independent Variable: Y, Dependent Variable: X

Step-by-step explanation:

Explanation for A:

We form a simple equation, knowing that if he drinks y liters each day after one week it would be 7Y. Then, we'd subtract it from 4

So equation would be X = 4 - 7Y

Explanation for B:

The independent is Y because doesn't change or get affected by another variable, and the dependent variable is X because depending on the value of Y, X will change accordingly.

Regan and her friends shared a Big Dipper sundae at Skylight Ice Cream Shop. The 3 of them split the bill, and each person paid $3.75.
Let b represent the total cost of a Big Dipper sundae. Which equation models the problem?

Answers

Answer: B=$3.75×3

Explanation: we want the full price of the Big Dipper so the equation will equal to B, there were 3 friends that split the bill $3.75 each so if we multiple 3.75 by 3 we will get the total cost of the Big Dipper which is $11.25

The solution is: b=$3.75×3, the equation models the problem, when b represent the total cost of a Big Dipper sundae.

Here, we have,

____ kilometers

Answers

Answer:

3.602 km.

Hope this helps!

Answer: If t would be the number of days, d the distance they built and x the total they built, then the relationship would be x = td.

Step-by-step explanation: If they build a certain amount of road every day, then in two days, they're gonna build twice that much road, in three days triple, etcetera. Therefore you just need to multiply the amount of days they work with the amount of road they build in a day.

Ximena conducts a survey on how students spend their money.
Sample: 80 students randomly chosen as they leave the school.
Question: Do you spend the majority of your money keeping up with today's hottest music or on other things?
Claim: Students spend the majority of their money buying music.

Answers

Answer:

The claim that students spend the majority of their money buying music is not valid. The survey Ximena conducted is not representative of the entire population of students, as it only surveyed 80 students randomly chosen as they left the school.

Question 2(Multiple Choice Worth 2 points)
(Experimental Probability MC)

In a repeated experiment, Kim rolled a fair die twice. The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36. Predict how many times the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.

3
9
10
18

Answers

Answer is simply 3 :)))))))

9 the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36.

As, Expected number of outcomes = theoretical probability * number of trials

Expected number of outcomes = 3/36 x 108

= 9

Thus, the required value is 9.

#SPJ2

surface area of cuboid

Answers

Answer:

Volume equals 60

Step-by-step explanation:

volume = (width)(height)(length)

volume= (2.5)(4)(6)

volume= 60

The amount of glass used is equivalent to the surface area of the glass surfaces.

As the problem is specifying the top of the aquarium is open, we'll assume that it is not included for the surface area calculations.

[tex]A=2 (2.5 \times 4) +2(6\times4)+(6\times2.5)[/tex]

The first term represents the area of two 2.4 x 4 faces of the aquarium. The second term is the area for the two 6 x 4 faces. The last term is for the 6 x 2.5 base of the aquarium, and it is not multiplied by 2 as we are not including the top of the aquarium.

[tex]=2 \times 10 + 2\times24 + 15[/tex]

[tex]=83 \text{ ft}^2[/tex]

The aquarium has a surface area of 83 square feet. Hence, 83 square feet of glass was used to build the tank.
