The figure shows a blueprint of a dining room, kitchen, and living room. Each square has a side length of 1/4 inch. Tile costs $7 per square foot. What is the cost of the tile for the kitchen?
The cost of the tile for the kitchen is $___
Answers
Answer:
The cost of the tile for the kitchen is $1,680
Step-by-step explanation:
step 1
we know that
The scale drawing is [tex]\frac{1}{16}\frac{in}{ft}[/tex]
The dimensions of the kitchen in the blueprint are
L=3(1/4)=3/4 in
W=5(1/4)=5/4 in
step 2
Find the actual dimensions of the kitchen
Divide the dimensions of the kitchen in the blueprint by the scale drawing
L=(3/4)/(1/16)=12 ft
W=(5/4)/(1/16)=20 ft
The area is equal to
A=(12)(20)=240 ft²
step 3
Find the cost of the tile for the kitchen
7(240)=$1,680
Answer:
Cost of the tiles for the kitchen is $1680
Step-by-step explanation:
From the figure attached,
Dimensions of the kitchen = 5 small squares by 3 small squares
Since 1 small square = [tex]\frac{1}{4}[/tex] inch
So the dimensions of the kitchen in inches = [tex]\frac{5}{4}[/tex] inches by [tex]\frac{3}{4}[/tex] inches
Map Scale has been given as
1 inch = 16 ft
Therefore actual dimensions of the kitchen will be
[tex]\frac{5}{4}\times 16[/tex] ft by [tex]\frac{3}{4}\times 16[/tex] ft
= 20 ft by 12 ft
Area of the kitchen = 20×12
= 240 ft²
Per square feet tile cost = $7
So the cost of tiling 240 ft² will be = 240 × 7
= $1680
Therefore, cost of the tiles for the kitchen is $1680

Replace x with 3 and solve for Y.
If y equals 8 in both equations, then it is a solution.
y = -5(3) +1 = -15+1 = -14
-14 does not equal 8 , so it is not a solution.
No because -5• 3 +1 does not equal 8 makings it impossible for it to work for that equation. Then 3•3-2 doesn’t equal 8 either so (3,8) is not a solution for these equations
A rectangle's length and width are in a ratio of 5:2. The area is 160 square centimeters. What are the length and width?
If you could solve this please do so asap
Answers
Answer: The length and width are 20 square centimeters and 8 square centimeters
Explain: 20:8 can be reduced to 5:2 as a ratio. 20 times 8 equals 160.
Answer:
length = 20 cm and width = 8 cmStep-by-step explanation:
l - length
w - width
length and width are in a ratio of 5:2
[tex]\dfrac{l}{w}=\dfrac{5}{2}[/tex] cross multiply
[tex]2l=5w[/tex] divide both sides by 2
[tex]l=\dfrac{5w}{2}[/tex]
the area is 160cm²
[tex]lw=160[/tex]
We have the system of equations:
[tex]\left\{\begin{array}{ccc}l=\dfrac{5w}{2}&(1)\\lw=160&(2)\end{array}\right[/tex]
Substitute (1) to (2):
[tex]\left(\dfrac{5w}{2}\right)(w)=160\\\\\dfrac{5w^2}{2}=160\qquad\text{multiply both sides by 2}\\\\5w^2=320\qquad\text{divide both sides by 5}\\\\w^2=64\to w=\sqrt{64}\\\\w=8[/tex]
Put the value of w to (1):
[tex]l=\dfrac{(5)(8)}{2}=\dfrac{40}{2}=20[/tex]
Write the number 7 ones 9 tens 9 hundreds
Answers
Answer:
997
From right to left, the place values are, ones, tens, hundreds, thousands, etc.
The number with '7 ones', '9 tens', and '9 hundreds' is written as 997 in numeral form, by combining the values of each digit based on their place value.
When writing the number that consists of '7 ones', '9 tens', and '9 hundreds', we are dealing with a three-digit number where each place value represents a power of 10. To construct the number, we consider the value each digit represents:
The '9 hundreds' means 9 × 100 (which is 900).
The '9 tens' means 9 × 10 (which is 90).
The '7 ones' means 7 × 1 (which is 7).
Adding these values together, we have 900 (hundreds) + 90 (tens) + 7 (ones), which equals 997. This is the decimal representation of the number expressed by the student.
Therefore, the number 7 ones 9 tens 9 hundreds written in numeral form is 997.
Divide 4200 by a multiple of 10 so that the quotient is also a multiple of 10
Answers
Answer:
4200 divided by 10
Step-by-step explanation:
To make 4200 a multiple of ten after dividing it by a multiple of ten, we first find the number of 5's in 4200 to see how many 10's go into 4200. Since 4200 = 6*7*2*2*5*5, we see that there are 2 fives. This means that there are two tens too. Since we have to keep 4200 a multiple of ten after dividing it by another 10. So the only possible way to do that is dividing 4200 by 10.
Dividing 4200 by the power of 10, 100, results in the quotient 42, which is also a multiple of 10. This is achieved by moving the decimal point two places to the left in the number 4200 due to the two zeros in the power of 10.
Explanation:In this mathematics problem, you are asked to divide 4200 by a multiple of 10 such that the result, or quotient, is also a multiple of 10. The key to this problem lies in understanding the concept of dividing by powers of 10.
When you divide a number by a power of 10, you move the decimal point to the left by as many places as there are zeros in the power of 10. So if you wanted to divide 4200 by a multiple of 10 so that the result is also a multiple of 10, you might choose 100 (10^2) as your divisor. Why? Because there are two zeros in the power of 10, which means you move the decimal point two places to the left in the number 4200.
So when you divide 4200 by 100, you get 42 which is a multiple of 10. Therefore, 4200 divided by a multiple of 10 (100 in this case) gives a quotient (42) that is also a multiple of 10.

Gayle and Jerry had some money. After their mother gave each of them $20, Gayle had twice as much money as Jerry and Jerry had $50 less than Gayle. How much money did Gayle have at first?
Answers
Answer:
$100
Step-by-step explanation:
To find out how much money Gayle initially had, we solved the two equations provided by the problem: G + 20 = 2(J + 20) and J + 20 = G + 20 - 50. Solving these equations, it was found that Gayle initially had $90.
Explanation:The question is asking us to figure out how much money Gayle had before their mother gave them each $20. Let's denote the amount of money Jerry initially had as J and the amount of money Gayle initially had as G. According to the problem, after the mother gave them $20 each, Gayle had twice the amount of Jerry's, which mathematically translates to G + 20 = 2(J + 20). Likewise, Jerry had $50 less than Gayle, which can be written as J + 20 = G + 20 - 50. Thus we are given a system of two equations that we can solve simultaneously.
Both equations can be simplified to G = 2J + 20 and J = G - 50. By substituting J = G - 50 in the first equation, we can solve for G to get G = 2(G - 50) + 20 which further simplifies to G = $90. Thus, Gayle initially had $90.

Answers
Answer:
Plain rolls: $16
Shinny rolls: $20
Step-by-step explanation:
So, we have 2 equations to start with, let p = plain rolls and s = shinny rolls:
1) 8p + 10s = 328
2) 9p + 2s = 184
We need to isolate one variable, usually I go for the one with the lowest multiplicative... so let's go for the '2s' and isolate the s from equation 2.
2s = 184 - 9p
3) s = (184 - 9p) / 2
And let's place that s equivalent into the first equation:
8p + 10 (184 - 9p)/2 = 328
8p + 5(184 - 9p) = 328
8p - 45p + 920 = 328
-37p = -592
p = 16
Then we go into any of the 3 equations to get the value of s. Let's take the 3rd equation, it will be simpler:
s = (184 - 9p) / 2 = (184 - 9*16) / 2
s = (184 - 144)/2 = 40/2 = 20
Then last step, we enter the values for s and p in one of the first equations to validate it. We haven't worked with first equation, so let's use that one:
8p + 10s = 328
8 (16) + 10 (20) = 328
128 + 200 = 328
328 = 328

To find the weight of Carmen's pet rabbit, an equation is set up: 2w - 1 = 9, where w represents the unknown weight of Carmen's rabbit. Solving the equation, we find that Carmen's rabbit weighs 5 pounds.
Explanation:To find the weight of Carmen's pet rabbit, we first need to translate the given information into a mathematical equation. The problem states that Angelo's pet rabbit weighs 1 pound less than twice the weight of Carmen's pet rabbit and Angelo's rabbit weighs 9 pounds. Let's denote the weight of Carmen's rabbit as w. The relationship can be written as:
2w - 1 = 9
To solve for w, we add 1 to both sides of the equation:
2w - 1 + 1 = 9 + 1
2w = 10
Now, we divide both sides by 2 to get the weight of Carmen's rabbit:
2w / 2 = 10 / 2
w = 5
Therefore, Carmen's pet rabbit weighs 5 pounds.

twice the difference of a numbrr and 8 is equal to 2.twice the difference of a number and 8 is equal to 2
Answers
Answer:
2(x-8)=8
x=12
Step-by-step explanation:
The equation for the given statement is 2(x-8)=2.
The given statement "Twice the difference of a number and 8 is equal to 2
What is an equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, the difference between a number and 8 can then be written as 'x-8'. Twice that amount would be 2(x-8). If it's equal to 2, you can say 2(x-8)=2.
Therefore, the equation for the statement is 2(x-8)=2.
