A mason will lay rows of bricks to build a wall. The mason will spread 3/8
inch of mortar on top of all but the last row of bricks. The finished wall will be 1/8
inches less than 4 feet high. Answer parts a and b below.

The mason wants to lay the bricks so that the shortest edge of each brick is vertical. How many rows of bricks are​ needed? Show your work.

Let b equal the number of rows of bricks. The total height of the bricks in inches is equal to _______ times _______
The total height of the mortar is equal to ______ times ______
Their sum is equal to the height of the wall or ______ inches.
If I write this as an equation and solve for​ b, then the result is ______ of bricks

The base is 30.

Hopefully I got this correct, not 100%

Answer: 30 ft

Step-by-step explanation:

Area of a triangle= (bh)/2

* multiply both sides by 2

2A=bh

*divide by h

(2A)/h=b

*substitute values

(2x120)/8=b

240/8=30

Answer: $251,535 is the total cost for all the laptops.

Step-by-step explanation:

615×409= 251,535

Answer:

[tex]total\ cost=\$251,535[/tex]

Step-by-step explanation:

For this exercise it is important to analize the information provided in the exercise.

According to the exercise, the of cost each computer is:

[tex]cost=\$409[/tex]

You know that the school district purchased 615 new laptops for their mobile labs; therefore, in order to calculate the total cost for all the laptops purchased, you must multiply the cost of one laptop ($409) by 615.

Therefore, you get that the total cost is the following:

[tex]total\ cost=(\$409)(615)\\\\total\ cost=\$251,535[/tex]

Answer:1.0

Step-by-step explanation: 0.999 repeating is not a whole number like 1.0

Answer:

1.0

Step-by-step explanation:

Look at where the numbers are placed, in regards to the decimal point.

If a number is 1 place before a decimal point (For example 5.0) it is in the ones place.

If a number is 1 place after a decimal point (For example 0.1) It is in the tenths place.

Any numbers that are to the right the decimal are smaller than numbers to the left!

Answer:

210

Step-by-step explanation:

Since the three numbers have no factors in common, you can get the LCM by multiplying all three numbers.

Answer:

N(p) = 22 + 10p

In graphing the function, N(p) = 22 + 10p

would be the slope and 10;

and 22 would be the y-intercept.

Step-by-step explanation:

Let p represents the number of transactions.

Each transaction is worth 10 points, then p transactions are worth 10p points.

Customers automatically earn 22 points when they sign up.

The total amount of points is

N(p) = 22 + 10p

In graphing the function, N(p) = 22 + 10p

would be the slope and 10;

and 22 would be the y-intercept.

The evaluation of the given mathematical expression 7•(x-8)-3 for x = 5 results in -24.

To evaluate the variable expression 7•(x-8)-3 for x = 5, we substitute the value of x into the expression.

This becomes 7•(5-8)-3, which simplifies to 7•(-3)-3, or -21-3. Therefore, the evaluation of the given expression for x = 5 is -24.

Answer:

15

Step-by-step explanation:

We can multiply powers with the same base

x^4⋅x^2=(x⋅x⋅x⋅x)⋅(x⋅x)=x^6

Properties of exponents are rules used to simplify mathematical expressions involving exponents. Examples are Power of a Power which means adding exponents when multiplying two expressions with the same base, and Quotient of Powers which is subtracting exponents when dividing two expressions with the same base.

The question is about the properties of exponents. In mathematics, the properties of exponents refer to the rules that guide how expressions involving exponents are handled. For example, when you multiply two expressions with the same base, you add the exponents (also known as the Power of a Power property). So, an exponent like x^3 * x^2 simplifies to x^(3+2) = x^5.

Another example is the quotient of powers property, where you subtract the exponents when dividing two expressions with the same base. So, an expression like x^5 / x^3 simplifies to x^(5-3) = x^2.

These are just a couple of the basic properties of exponents. Other properties include the power of a product, the power of a quotient, zero exponent, and negative exponent. Each of these properties follows specific rules to simplify the expression involving exponents.

Answer:

b) 91

Step-by-step explanation:

Step 1: Multiple marks by its weights

Homework average: 95 x 20% = 19

Quiz average: 90 x 20% = 18

Test average: 87 x 40% = 34.8

Final exam: y x 20% = 0.2y

Step 2: Add all weighted averages and find y

19+18+34.8+0.2y = 90

71.8 + 0.2y = 90

y = 18.2/0.2

y = 91

Therefore, Anna needs to score minimum 91 in the final exam so that she can score a 90 in class.

Answer:

12.50x+30

Step-by-step explanation:

Answer:

[tex]y = 12.5x + 30[/tex]

Step-by-step explanation:

We are given the following information in the question:

Cost of a holiday meal = $12.50

Delivery fee = $30

Cost(y) represents the amount a holiday meal including delivery for x people.

[tex]cost = (\text{Cost of meal}\times x) + \text{Delivery chareges}[/tex]

Putting all the values,

[tex]y = 12.50\times x + 30\\y = 12.5x + 30[/tex]

The above equation gives the total amount of holiday meal for x people including the delivery charges.

Answer:

18+t<26

t={1,2,3,4,5,6,7}

Step-by-step explanation:

18+t<26

alright, so you know that she will run less than 26. That means she cannot run 26 or 27 or any more miles than that.

She can run 19, 20, 21, 22, 23, 24, or 25 miles in total from her starting point which is 18.

She already ran 18 miles. If she ran one more it would be 19, if she ran 2 more it could be 20. But she CAN NOT pass 25 miles. (it is not less than OR equal to)

so let me put it like this:

18+1<26 yes because 18+1=19 which is less than 26

18+2<26 yes because 18+2=20 which is less than 26

18+3<26 yes because 18+3=21 which is less than 26

18+4<26 yes because 18+4=22 which is less than 26

18+5<26 yes because 18+5=23 which is less than 26

18+6<26 yes because 18+6=24 which is less than 26

18+7<26 yes because 18+7=25 which is less than 26

18+8<26 NOOO because 18+8=26 which is NOT less than 26 (it's equal, not less than)
