Sketch a rectangle and label its dimensions that meets the following conditions perimeter 18 area 20
Answer:
4 units by 5 units
Step-by-step explanation:
To solve this problem, then we must develop two equations; one for the perimeter and another for the area of the rectangle.
The perimeter of a rectangle = 2(L +B)
The area of a rectangle = L x B
Let the length be represented by L while the breadth is denoted by B. Then, our equations are
2L + 2B =18 --- eq 1
and
LB = 20 ----- eq 2
From eq 2, then L = 20/B
We shall substitute this in equation 1 such that
2(20/B) + 2B =18
= 40/B + 2B = 18
= 40/B + 2B/1 = (40 + 2B^2) /B =18
We do cross multiplication by multiplying both sides of the equation by B.
We get
40 + 2B^2 = 18B
We then rearrange the equation as 2B^2- 18B + 40 = 0
Dividing both sides by 2, we get B^2- 9B =20 =0
We shall get the roots of the equation to be -4 and -5. Why?
-4B-5B =-9 and -4x-5 =20
Thus, B^2- 9B =20 =0 can be reworked as
(B-4) (B-5)= 0 From B-4=0, B= 4
From LB =20, If B =4, then L =20/4 = 5
From B-5=0; B=5
From LB =20, If B=5, L = 20/5 = 4
Thus, the dimensions of the rectangle are 5 units and 4 units.

Find the total cost to the nearest cent.
$9,000 car: 5% sales tax
Answer:
$9,450.00
Step-by-step explanation:
to take sales tax, you convert the % into a decimal ( in this case 5% is equal to 0.05) and multiply that by the cost of the product:
9,000 x 0.05 = 450
that is the amount that you pay in tax. In order to get the entire total add that amount to the original price:
9,000 + 450 = 9,450

Which input value produces the same output value for the two functions on the graph?
x = −1
x = 0
x = 3
x = 4
Answer: x = 4
Step-by-step explanation:
Given : A coordinate grid with 2 lines.
One line, labeled f(x) passing through (- 3, 3), (0, 3), and the point (4, 3). (i)
The other line is labeled g(x) and passes through (- 4, -3), (0, 0), and the point (4, 3). (ii)
We generally denote x values as input values and y values as output values.
From (i) and (ii), the common point on both lines = (4,3)
Here, input value = 4
Output value = 3
Hence, the input value produces the same output value for the two functions on the graph : x=4

On a coordinate plane, a solid straight line has a positive slope and goes through (negative 4, negative 3), (0, negative 1), and (2, 0). Everything to the left of the line is shaded.
On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 4, negative 3), (0, negative 1), and (2, 0). Everything to the left of the line is shaded.
On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 4, negative 3), (0, negative 1), and (2, 0). Everything to the right of the line is shaded.
Answer:
Option 3
Step-by-step explanation:
Given : Linear inequality [tex]2y>x-2[/tex]
To find : Which is the graph of linear inequality ?
Solution :
Linear inequality [tex]2y>x-2[/tex]
First we figure out the slopes and coordinates through which it pass.
The linear equation is [tex]2y=x-2[/tex]
The general slope form of line is [tex]y=mx+c[/tex]
Where, m is the slope and c is the y-coordinate
Re-write the equation [tex]y=\frac{1}{2}x-1[/tex]
On compare,
Slope is positive [tex]m=\frac{1}{2}[/tex]
The y-coordinate is (0,-1)
For x-coordinate put y=0,
[tex]2(0)=x-2[/tex]
[tex]x=2[/tex]
The x-coordinate is (2,0).
Now, Plotting the linear inequality and mark the point (-4,-3).
Refer the attached figure below.
We get, On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 4, negative 3), (0, negative 1), and (2, 0). Everything to the left of the line is shaded.
Therefore, Option 3 is correct.
Final answer:
The correct graph of the linear inequality 2y > x - 2 will be represented by a dashed line with a positive slope, where the shaded area is above the line representing all points where y is greater than 0.5x - 1. Thus, option 3 is correct.
Explanation:
The graph of the linear inequality 2y > x – 2 must be represented by a dashed line because the inequality is strict (does not include the line itself). First, we should identify whether the line is dashed or solid and the slope of the boundary line from the equation. Since it is a 'greater than' and not 'greater than or equal to' inequality, the line will be dashed. Now let's rearrange the inequality to the slope-intercept form, which is y = mx + b, to find the slope and y-intercept:
2y > x – 2
y > 0.5x - 1
Here, the slope (m) is positive, which is 0.5, and the y-intercept (b) is -1. Therefore, the line rises by 0.5 on the y-axis for every increase of 1 on the x-axis. The y-intercept tells us the line will cross the y-axis at (0, -1). Hence, the line will have a positive slope, and the shaded region should be above the dashed line indicating all points where the y-values are greater than those on the line.
What’s the volume of a cone with a radius of 3cm and a height of 4.5cm
Answer:
42.41
Step-by-step explanation:
V=π[tex]r^{2}[/tex][tex]\frac{h}{3}[/tex]=π * [tex]3^{2}[/tex] * ≈ 42.4115
The volume of a cone with a radius of 3cm and height of 4.5cm is approximately 42.41 cubic centimeters.
The volume (V) of a cone can be found using the formula: V = (1/3)πr²h, where r is the radius of the base and h is the height of the cone. To find the volume of a cone with a radius of 3cm and a height of 4.5cm, we substitute these values into the formula:
V = (1/3)π(3cm)²(4.5cm)
Calculating this further:
V = (1/3)π(9cm²)(4.5cm)
V = (1/3)π(40.5cm³)
V ≈ (1/3)(3.14159)(40.5cm³)
V = 42.41cm³
Therefore, the volume of the cone is approximately 42.41 cubic centimeters.

Hanna shops for socks that cost $2.99 for each pair and blouses that cost $12.99 each. Let x represent the number of pairs of socks purchased, and let y represent the number of blouses purchased. Which equation models the purchases she made with $43.92?
x + y = 15.98
x + y = 43.92
43.92x - 2.99y = 12.99
2.99x + 12.99y = 43.92
Answer:
2.99x + 12.99y = 43.92
Step-by-step explanation:
Because, 2.99 is for each pair of socks and she bought x number of that. Same for 12.99 (Y).
In conclusion her total was 43.92 and she could have bought many socks as she'd like and blouses.

What else would need to be congruent to show that ABC = XYZ by ASA?
Given:
Z=C
CB=ZY
A. Y=B
B. AC=XZ
C. BC=YZ
D Z=A
The answer would be A because line CB is equivalent to ZY tight? And angles Z and C are congruent. We also know that they are congruent by a ASA relationship, so then angles Y and B are congruent, the answer is A.
To establish that triangles ABC and XYZ are congruent by ASA, we need two pairs of angles and one pair of sides to be congruent. Given that angle Z equals angle C, side CB equals side ZY, the missing piece is option D: Z equals A.
Explanation:In the problem statement, we're given that triangle ABC = XYZ by ASA, which stands for Angle-Side-Angle congruence. To establish this, we require two angles and one side of the triangle to be congruent. The given details tell us that angle Z is congruent to angle C, and side CB is congruent to side ZY.
To complete the ASA proof, we need another pair of angles to be congruent. Based on the options presented in the question, option D Z=A will fulfill this requirement, thereby proving ABC = XYZ by ASA.

you only have a 1/4 measuring cup and a recipe calls for 8 3/4 cups of flour how many 1/4 cups would you need to use?
Answer:
35 cups are needed.
Step-by-step explanation:
We have to divide 8 3/4 by 1/4.
Convert to improper fraction.
8 3/4 = [(8*4) + 3] / 4
= 35 / 4.
35/4 / 1/4
= 4*35 / 4
= 35 cups.
To measure out 8 3/4 cups of flour using a 1/4 measuring cup, you would need to use 35 1/4 cups.
Explanation:To determine how many 1/4 cups you would need to use, you can divide the total amount of flour required by the size of the measuring cup. In this case, the recipe calls for 8 3/4 cups of flour. So, you would divide 8 3/4 by 1/4.
When you divide a fraction by another fraction, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1/4 is 4/1, which is the same as 4. So, 8 3/4 ÷ 1/4 is equal to 8 3/4 * 4, which is 35.
Therefore, "you would need to use 35 1/4 cups to measure out 8 3/4 cups of flour".

Change the denominator (the bottom number of the fraction) into something both can go into. 4 can go into 8 and 8 can go into 8. Rewrite the fractions beside the actual numbers. Example: /8 and /8 then remember, 4 goes into 8 two times. So do 1x2=2. Then remember 8 goes into 8 1 time so do 3x1=3. Add the two fractions 3/8+2/8= 5/8. Then add the whole numbers as well. 7+3+5/8= 10 5/8. I know that it's really confusing explaining it through words but if you ever need further explanation don't hesitate to ask! :)
