Blank # 2
Blank # 3
Answer:
The kitchen requires 288 sq. ft. of tile
The master bathroom requires 180 sq. ft. of tile
In total, we will spend $1170
Step-by-step explanation:
The area of the kitchen is length * width:
Area of Kitchen = [tex]18*16=288[/tex] sq. ft.
The area of the master bathroom is length * width:
Area of Master Bathroom = [tex]12*15=180[/tex] sq. ft.
The kitchen requires 288 sq. ft. of tile
Question 2: " How many square feet of tile will I need for the bathroom?"The master bathroom requires 180 sq. ft. of tile
Question 3: "If the tile costs $2.50 per sq ft, how much money will I spend on tile?"In total, we require [tex]288+180=468[/tex] sq. ft. of tiles. If $2.50 is charged per square feet, in total we will spend:
[tex]468*2.5=1170[/tex] dollars
You'll need 288 square feet of tile for the kitchen, 180 square feet for the bathroom, and the total cost for the tile will be $1170.
To calculate the amount of tile needed for the kitchen and the master bathroom, you first need to determine the area of each room. Area is calculated by multiplying the length by the width of the room.
For the kitchen:
Length = 18 feet
Width = 16 feet
Area = Length x Width = 18 ft x 16 ft = 288 square feet
For the master bathroom:
Length = 15 feet
Width = 12 feet
Area = Length x Width = 15 ft x 12 ft = 180 square feet
To calculate the total cost of the tile:
Cost per square foot = $2.50
Total area = Area of kitchen + Area of bathroom = 288 sq ft + 180 sq ft = 468 square feet
Total cost = Total area x Cost per square foot = 468 sq ft x $2.50 = $1170
Quadrilateral ABCD is located at A(−2, 2), B(−2, 4), C(2, 4), and D(2, 2). The quadrilateral is then transformed using the rule (x + 2, y − 3) to form the image A'B'C'D'. What are the new coordinates of A', B', C', and D'? Describe what characteristics you would find if the corresponding vertices were connected with line segments.
Answer:
A' (0, -1)
B' (0, 1)
C' (4, 1)
D' (4, -1)
Step-by-step explanation:
We have the following points of a quadrilateral ABCD:
A(−2, 2), B(−2, 4), C(2, 4), and D(2, 2)
and the rule of the translation is given by:
(x, y) ---> (x + 2, y − 3)
which means that each point will move means 3 units to the left and 4 units upwards.
So the points after transformation will be:
A(−2, 2) ---> (-2+2, 2-3) ---> A' (0, -1)
B(−2, 4) ---> (-2+2, 4-3) ---> B' (0, 1)
C(2, 4) ---> (2+2, 4-3) ---> C' (4, 1)
D(2, 2) ---> (2+2, 2-3) ---> D' (4, -1)
If we plot these points on a graph and join the corresponding vertices with line segments, then we will see that all the the lines will be parallel to each other since they followed the same rule of transformation.
The new coordinates of the transformed vertices A', B', C', and D' are:
A' (0, -1)
B' (0, 1)
C' (4, 1)
D' (4, -1)
To find the new coordinates of the transformed vertices A', B', C', and D', you need to apply the transformation rule (x + 2, y - 3) to the original coordinates of A, B, C, and D.
A' = (x + 2, y - 3)
A' = (-2 + 2, 2 - 3)
A' = (0, -1)
B' = (x + 2, y - 3)
B' = (-2 + 2, 4 - 3)
B' = (0, 1)
C' = (x + 2, y - 3)
C' = (2 + 2, 4 - 3)
C' = (4, 1)
D' = (x + 2, y - 3)
D' = (2 + 2, 2 - 3)
D' = (4, -1)
So, the new coordinates of the transformed vertices A', B', C', and D' are:
A' (0, -1)
B' (0, 1)
C' (4, 1)
D' (4, -1)
Now, let's describe the characteristics of the quadrilateral ABCD and its image A'B'C'D' when the corresponding vertices are connected with line segments:
Quadrilateral ABCD:
A(−2, 2), B(−2, 4), C(2, 4), and D(2, 2)
ABCD is a trapezoid with two parallel sides (AB and CD) and two non-parallel sides (BC and AD).
The trapezoid is located in the first quadrant.
Image A'B'C'D':
A'(0, -1), B'(0, 1), C'(4, 1), and D'(4, -1)
A'B'C'D' is also a trapezoid with two parallel sides (A'B' and C'D') and two non-parallel sides (B'C' and A'D').
A'B'C'D' is located in a different position due to the transformation. It has been shifted 2 units to the right and 3 units down.
The transformation (x + 2, y - 3) has effectively shifted the entire quadrilateral 2 units to the right and 3 units down in the coordinate plane. The basic shape and characteristics of the trapezoid are preserved, but its position in the plane has changed.

1)Meesha has a pocket full of change consisting of dimes and quarters. The total value is $3.15. There are 7 more quarters than dimes. How many of each coin are there?
2)How much pure bleach must be combined with a solution that is 4% bleach to make 12oz of a 12% bleach solution?
Please help me
Answer:
1) 11 quaters and 4 dimes
Step-by-step explanation:
1) 11 quaters = 2.75
4 dimes = .40
$2.75 + .40 = 3.15
Final answer:
Meesha has 4 dimes and 11 quarters. To make a 12oz 12% bleach solution, 1 ounce of pure bleach must be combined with a 4% solution.
Explanation:
Solving Coin and Bleach Solution Problems
Problem 1: Coin Combination
Meesha has dimes and quarters adding up to $3.15, with 7 more quarters than dimes. To solve this, let's denote the number of dimes as d and the number of quarters as q. We have two equations based on the problem statement:
0.10d + 0.25q = 3.15 (The total value in dollars.)
q = d + 7 (There are 7 more quarters than dimes.)
Substituting the second equation into the first gives:
0.10d + 0.25(d + 7) = 3.15
This simplifies to:
0.10d + 0.25d + 1.75 = 3.15
Combining like terms:
0.35d = 3.15 - 1.75
0.35d = 1.40
Dividing both sides by 0.35 gives:
d = 1.40 / 0.35 = 4
Therefore, there are 4 dimes and substituting back:
q = 4 + 7 = 11 quarters.
Problem 2: Mixing Bleach Solutions
To make a 12oz 12% bleach solution from a 4% solution, let's denote the amount of pure bleach needed as b ounces. The amount of 4% solution would then be 12 - b ounces. The equation representing the mixture is:
(12 - b) * 0.04 + b = 12 * 0.12
This simplifies to:
0.48 - 0.04b + b = 1.44
0.96b = 0.96
b = 0.96 / 0.96 = 1 ounce of pure bleach is needed.
Use the substitution method to solve the system of equations

The height of a triangle is 2 less than 5 times its base. If the base of the triangle is x feet, and the area of the triangle is 12 square feet, which equation models this situation?
A. 5x2 − 2x − 24 = 0
B. 5x2 − 2x − 6 = 0
C. 5x2 − 2x − 12 = 0
D. 25x2 − 10x − 24 = 0
Answer:
A. 5x^2 − 2x − 24 = 0
Step-by-step explanation:
height = 5b-2
b =x
We can rewrite the height as
h = 5x-2
We know the formula for area of a triangle
A = 1/2 bh
A =1/2 x * (5x-2)
Distributing the x
A= 1/2 (5x^2 - 2x)
We know A =12
12 = 1/2 (5x^2 - 2x)
Multiply each side by 2
12*2 = 2*1/2 (5x^2 - 2x)
24 = 5x^2 - 2x
Subtract 24 from each side
24-24 = 5x^2 - 2x-24
0 = 5x^2 - 2x-24
Answer:
C. 5x^2 − 2x − 24 = 0

write an equation in slope- intercept form y=mx=b of the line through point p(6,7) with slope -2
Answer:
The equation would be y = -2x + 19
Step-by-step explanation:
To find this, we can use the point and the slope in point-slope form. The we solve for y.
y - y1 = m(x - x1)
y - 7 = -2(x - 6)
y - 7 = -2x + 12
y = -2x + 19
To write an equation in slope-intercept form, use the formula y = mx + b. In this case, substitute the given point and slope into the equation.
Explanation:To write an equation in slope-intercept form, we need to use the formula y = mx + b, where m is the slope and b is the y-intercept. In this case, we are given a point P(6,7) and a slope of -2. We can substitute these values into the equation to find the y-intercept.
Using the point-slope form of the equation: y - y1 = m(x - x1), we substitute x1 = 6, y1 = 7, and m = -2. This gives us the equation: y - 7 = -2(x - 6).
Distributing the -2 on the right side of the equation, we get: y - 7 = -2x + 12. Finally, we can rearrange the equation to slope-intercept form by isolating y on one side: y = -2x + 12 + 7, which simplifies to y = -2x + 19.

Answer:
2A/h - b1 = b2
Step-by-step explanation:
A = 1/2 h ( b1+b2)
We want to solve for b2
Multiply each side by 2
2A = 2* 1/2 h ( b1+b2)
2A = h ( b1+b2)
Divide each side by h
2A / h = h/h ( b1+b2)
2A / h = b1+b2
Subtract b1 from each side
2A/h - b1 = b1 + b2 -b1
2A/h - b1 = b2

Quadrilateral ABCD is a parallelogram if both pairs of opposite angles are congruent. Prove that quadrilateral ABCD is a parallelogram by finding the measures of the opposite angle pairs?
A) 95°, 85°
B) 105°, 75°
C) 115°, 65°
D) 125°, 55°
Answer:
See below
Step-by-step explanation:
For a parallelogram m < A = m < C so:-
75 + 5x = 87 + 3x
2x = 12
x = 6
and m< A = 75 + 30 = 105
and m < C = 87 + 18 = 105
Now if the other 2 angles are = 75 degrees( that is the same side angles add up to 180 degrees) we have proved that it is a parallelogram.
m < B = m < D
111 - 6x = 39 + 6x
-12x = -72
x = 6
m < B = 111 - 36 = 75 and m < D = 39 + 36 = 75
So this has been proved.
To prove that quadrilateral ABCD is a parallelogram, solve for x to find the values that make the opposite angles congruent. Plug in the values of x to find the measures of the opposite angle pairs. None of the given answer choices are correct.
Explanation:To prove that quadrilateral ABCD is a parallelogram, we need to show that both pairs of opposite angles are congruent. We are given the measures of the angles using variable expressions. We can set the expressions for opposite angles equal to each other and solve for x to find the values of x that make the opposite angles congruent. Finally, we plug in the values of x to find the measures of the opposite angle pairs.
Step 1: Set the expressions for opposite angles equal to each other: 75 + 5x = 39 + 6x and 111 - 6x = 87 + 3xStep 2: Solve the equations for x. For the first equation, subtract 5x and 39 from both sides to get -64 = x. For the second equation, subtract 87 and 3x from both sides to get 24 = 9x. Divide both sides by 9 to get x = 8/3.Step 3: Plug in the values of x into the expressions for the opposite angles to find their measures. For angle A, substitute x = -64 into 75 + 5x to get 75 + 5(-64) = -205. For angle D, substitute x = -64 into 39 + 6x to get 39 + 6(-64) = -375. For angle B, substitute x = 8/3 into 111 - 6x to get 111 - 6(8/3) = 89. For angle C, substitute x = 8/3 into 87 + 3x to get 87 + 3(8/3) = 95.Step 4: Check if the opposite angles are congruent. Angle A and angle C have measures of -205 and 95, respectively, which are not congruent. Angle B and angle D have measures of 89 and -375, respectively, which are also not congruent.Since the opposite angles are not congruent, we cannot conclude that quadrilateral ABCD is a parallelogram. Therefore, none of the given answer choices (A) 95°, 85°, (B) 105°, 75°, (C) 115°, 65°, or (D) 125°, 55°, are correct.

Trever and Marisa together have 28 t shirts to sell if marissa has 4 fewer t shirts than trevor find how many t shirt Trevor has
Answer:
Trevor has 16 number of shirts
Step-by-step explanation:
We have been given that Trevor and Marisa together have 28 t shirts to sell if Marissa has 4 fewer t shirts than Trevor
let the number of shirts Trevor have be x
And since, Marissa has 4 fewer than Trevor so number of shirts Marissa will have be x-4
Hence, according to question equation becomes:
x+x-4=28
We will solve for x to find the number of t shirts Trevor has
2x -4 =28
2x = 32
x =16
Hence, Trevor has 16 number of shirts

Alaina is selling wreaths and poinsettias for her chorus fundraiser. Wreaths cost $27 each poinsettia cost $20 each. If she sold 15 poinsettias and made $543, how many wreaths did she sell?
Answer:
The number of wreaths Alaina sells is 9 .
Step-by-step explanation:
As given
Alaina is selling wreaths and poinsettias for her chorus fundraiser.
Wreaths cost $27 each poinsettia cost $20 each.
If she sold 15 poinsettias and made $543.
Let us assume that the number of wreaths Alaina sells = x
As the number of poinsettias Alaina sells = 15
Than the equation becomes
27x + 15 × 20 = 543
27x + 300 = 543
27x = 543 - 300
27x = 243
[tex]x = \frac{243}{27}[/tex]
x = 9
Therefore the number of wreaths Alaina sells is 9 .
Alaina sold 9 wreaths. After calculating the revenue from poinsettias ($300), the remaining amount ($243) was divided by the cost of one wreath ($27) to find the number of wreaths sold.
To determine how many wreaths Alaina sold, we first need to calculate the total revenue from selling 15 poinsettias. Since each poinsettia costs $20, we multiply 15 by $20:
15 poinsettias x $20/poinsettia = $300Now, subtract the total revenue from poinsettias from the total amount made:
$543 total made - $300 from poinsettias = $243 remainingThis remaining amount must be from the sale of wreaths. Since each wreath costs $27, we divide $243 by the cost of one wreath:
$243 / $27 per wreath = 9 wreaths soldTherefore, Alaina sold 9 wreaths.

b&b inc. has ordered machine parts and receives a charge of $15 for shipping and handling plus $20 per part. write an equation that represents the cost c of ordering p parts.
Answer:
C = 15 + 20*p
Step-by-step explanation:
Cost for ordering = shipping and handling plus cost per part * number of parts
C = 15 + 20*p
The linear equation representing the cost of ordering machine parts from B&B Inc. is c = 15 + 20p. This accounts for a fixed shipping cost of $15 and a variable cost of $20 per part.
Explanation:The subject of this question is linear equations in Mathematics. B&B Inc. is ordering machine parts and incurs a fixed shipping and handling cost of $15, plus a variable cost of $20 per part. The equation representing this situation can be developed with 'c' representing the total cost and 'p' representing the number of parts ordered. Considering the fixed and variable costs, the equation would be c = 15 + 20p where $15 is the fixed shipping and handling cost, and $20p represents the variable cost which depends on the number of parts ordered.
