A student answers 75% of the questions on a math exam correctly. if he answered 60 questions correctly, how many questions are on the exam?​

Answer:

Step-by-step explanation:

The formula for slope is

(y2-y1)/(x2-x1)

1. (1-5)/(-1-(-2) = -4/1 = -4

2. (3-1)/(7-(-1) = 2/8 = 1/4

3. (3-5)/7-(-2) = -2/9

Hope this helps! :)

Answer:

Step-by-step explanation:

First you find the coordinates. Once you have your starting point, you use the slope in the equation to start graphing the line. Since the numerator is negative, the line is going down. The denominator is a 1 so it will be going 1 unit to the right. The x intercept would be the first point of contact on the x axis, which would be (1,0)

Answer:

x intercept = 6, 0

y intercept = 0, 2

Step-by-step explanation:

Answer: 6

Step-by-step explanation:

Given: Amount of sugar he has = [tex]\dfrac34[/tex] pounds

Amount of sugar is required for each batch = [tex]\dfrac18[/tex] pounds

Now, the  greatest number of batches of cookies the baker can make with the [tex]\dfrac34[/tex] pounds of sugar = [tex]\dfrac{\dfrac{3}{4}}{\dfrac{1}{8}}=\dfrac{3}{4}\times\dfrac{8}{1}[/tex]

[tex]=3\times2=6[/tex]

Hence, the greatest number of batches of cookies the baker can make = 6

1. 30+35

2. 60+5

3. 66-1

Answer:

The minimum package Stan need to buy  so that all his guests get a party favor is 4 packages.

Step-by-step explanation:

Given;

total number of guest in the party = 20

number of party favor needed = 20 party favors

1 package = 6 party favor

then, 2 package = 12 party favor

         3 package = 18 party favor

         4 package = 24 party favor

24 party favor will serve all the guest.

Therefore, the minimum package Stan need to buy  so that all his guests get a party favor is 4 packages.

Answer:

y = 20- 1.50x

Step-by-step explanation:

x represents each day.

Answer:

x = 16

Step-by-step explanation:

1/2(x-4) = 1/3(x+2)

Multiplying through by the LCM,6 to take off the denominators;

6 × 1/2(x-4) = 6 × 1/3(x+2)

Simplifying;

3(x-4) = 2(x+2)

3x -12 = 2x + 4

Grouping like terms;

3x - 2x = 4 + 12

x = 16

Answer:

100a + 400 ≤ 6500

Step-by-step explanation:

The office building contains 6500 ft² of space. Each employee has a cubicle that  takes up to 100 ft². The entryway also takes up to 400 ft². The inequality that can be use to find the possible number of cubicles is expressed below.

Let

number of employee/cubicle = a

Total space of the office building =  6500 ft²

The entryway has already occupied 400 ft² of the office building space. Each employee has one cubicle which takes up to 100 ft² of the office building space. The space occupied by the cubicle in the office building can be calculated when you multiply the number of cubicle/employee by 100(size of each cubicle) This will be 100 × a = 100a. The total number of space occupied by the cubicles plus the already space taken by the entryway will be less than or equal to the total space of the office building. Therefore,

100a + 400 ≤ 6500

Answer:

100a + 400 ≤ 6500

Step-by-step explanation:

The space occupied by the cubicle in the office building can be calculated when you multiply the number of cubicle/employee by 100(size of each cubicle)

32 is the answer I am writing more so I have enough characters to submit

Answer: The answer to this basic math question with the given basic math expression is 32.

Step-by-step explanation: Mmmm, that was extremely easy, so anyway, here are 4 basic steps in order to evaluate the given basic expression:

Step 1. First, let's input the original basic equation that looks in the basic equation form like this: [tex]9+9+9+5.[/tex]

Step 2. After we input the original basic equation, next, let's add 9 and 9 that looks in the basic equation form like this: [tex]18+9+5.[/tex]

Step 3. Then, after we add 9 and 9, let's add 18 and 9 that looks in the basic equation form like this: [tex]27+5.[/tex]

Step 4. Last but not least is after we add 18 and 9, finally, let's add 27 and 5 altogether, and therefore your answer to this basic math question with the given basic math expression is 32.

I hope that my full given answer with my full given step-by-step explanation is very helpful to your own basic math question with the given basic math expression, please mark me as Brainliest, take care, always be safe, and have a great rest of the day and good night! :D

Answer: At 5:00 pm the second train catch up with the first train.

Step-by-step explanation:

Let t = Time taken by first train.

Time taken by second train = t-2

Speed of train 1 = 45 mph

Speed of train 2 = 55 mph

Since, Distance = speed x time

Then, [tex]45t= 55(t-2)[/tex]

[tex]\Rightarrow\ 45t= 55t-110[/tex]

[tex]\Rightarrow\ 55t-45t=110= \\\\\Rightarrow\ 10t=110\\\\\Rightarrow\ t=11[/tex]

After 11 hours, time = 8+11 =17(12+5)i.e. 5 : 00 pm.

Hence, At 5:00 pm the second train catch up with the first train.

answer:

f(x)=2x-10

y=2x-10

interchanging value of x and y,

x=2y-10

y=(x+10)/2

Answer:

(-4,-1,1,9)

Step-by-step explanation:

The range of domain refers to the set of possible input values, of all the input values. hence the range is the set of possible output values.

the given function is g(x)= x to the 2nd power -2--------expressed mathematically is

[tex]g(x)= x^-2[/tex]

The range of input values are (-2,-1,1,3)

what is expected of you is to put the input values as x in the given function and the output is the result.

so for -2

g(-2)=(-2)^-2=-(-2*-2)=-(4)=-4

the output is -4

so for -1

g(-1)=(-1)^-2=-(-1*-1)=-(1)=-1

the output is -1

so for 1

g(1)=(1)^-2=(-1*-1)=1

the output is 1

so for 3

g(3)=(3)^-2=(-3*-3)=9

the output is 9

Therefore all the outputs are (-4,-1,1,9) which is the range of the domain

Step-by-step explanation:

The time taken by the teams to finish the game is 6 hours.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that The Lakeside Legends, a broomball team, joined a 16-team league. They played each of their 15 opponents 3 times. Every broomball game lasts for exactly 2 hours.

The time taken will be calculated as,

Time = 3 x 2

Time = 6 hours
