A rectangle is 6yards longer than it is wide. Find the dimensions of the rectangle if it’s area is 187 square yards
Answer:
Width = 11 yards
Length = 17 yards
Step-by-step explanation:
First of all, the length of the rectangle is 6 yards longer than the width, this means, length = width + 6 yards. This dimensions can be represented on figure 1, where w is width, and l, for length.
We know the area of a rectangle is A = width x length
For our case 187 = w . (w + 6)
Using the Distributive Property for the multiplication we obtain
[tex]187 = w^{2} +6w[/tex]
[tex]w^{2} +6w-187 =0,[/tex]
Using the quadratic formula [tex]w=\frac{-b\±\sqrt{b^{2}-4ac } }{2a}[/tex] where a = 1, b = 6, c = - 187 and replacing into the formula, we will have:
[tex]w=\frac{-6\±\sqrt{6^2-4(1)(-187)} }{2(1)}[/tex]
[tex]w=\frac{-6\±\sqrt{36+748} }{2}=\frac{-6\±\sqrt{784} }{2}=\frac{-6\±28}{2}[/tex]
We have two options: [tex]w=\frac{-6+28}{2}=\frac{22}{2}=11 yards[/tex]
Or
[tex]w=\frac{-6-28}{2}=\frac{-34}{2}=-17 yards[/tex] But a distance (width) can not be negative so, this answer for w must be discarded.
The answer must be width = 11 yards.
To find the length [tex]l =\frac{187}{11}=17 yards[/tex]

[tex]\begin{array}{cc}\text{Zac's score}&\text{Natan's score}\\ 6&1\\7&3\\8&5\\9&7\end{array}[/tex]
Step-by-step explanation:
Nathan's score is 11 less than 2 times Zac's score.
Let Z points be Zac's score and N points be Natan's score. then
2 times Zac's score = 2Z
11 less than 2 times Zac's score = 2Z -11
So, N = 2Z - 11
1. If Z=6, then [tex]N=2\cdot 6-11=12-11=1[/tex]
2. If Z=7, then [tex]N=2\cdot 7-11=14-11=3[/tex]

Write the equation of the line in slope-intercept form that is parallel given the equation and point.
Answer:
[tex]y = \frac{4x}{5}+\frac{42}{5}[/tex]
Step-by-step explanation:
In order for two lines to be parallel, they must have the same slope. So, we know that the slope of the other line is 4/5.
We're given an ordered pair, so we can solve for [tex]b[/tex] in the (slope-intercept form) equation [tex]y = mx + b[/tex]
[tex]2 = \frac{4}{5}(-8) + b\\2 = \frac{-32}{5}+b\\b = 2 + \frac{32}{5}\\ b = \frac{42}{5}[/tex]
[tex]y = \frac{4x}{5}+\frac{42}{5}[/tex]

Part 1) 9 and 1 over 2 divided by 1 over 4
Part 2) 18, because the number of catalogs is 72 over 5 divided by 4 over 5
Part 3) 3.2
Part 4) 3.6 with bar over 6
Part 5) 4 over 7 and 4 over 9
Part 6) 43 over 9
Part 7) Benny spent to go to the summer camp $280.00
Part 8) $124
Part 9) (−$11) ⋅ 12
Part 10) -27 ft
Step-by-step explanation:
Part 1)
Let
x ------> the number of days
we now that
The total distance jogged must be equal to the distance jogged each day multiplied by the number of days
[tex]9\frac{1}{2}=\frac{1}{4}x[/tex]
Solve for x
[tex]x=\frac{9\frac{1}{2}}{\frac{1}{4}}[/tex]
therefore
The number of days is
9 and 1 over 2 divided by 1 over 4
Part 2)
Let
x ----> the number of catalogs
we know that
To find out the number of catalogs, divide the wide of the shelf by the thick of each catalog
[tex]x=\frac{\frac{72}{5}}{\frac{4}{5}} =\frac{72}{4}= 18\ catalogs[/tex]
therefore
18, because the number of catalogs is 72 over 5 divided by 4 over 5
Part 3) Convert 16 over 5 to a decimal
we know that
[tex]\frac{16}{5}=16(\frac{1}{5})=16(0.2) =3.2[/tex]
Part 4) How can 33 over 9 be expressed as a decimal?
we know that
[tex]\frac{33}{9}= 3.666666...[/tex] ----> is a repeating decimal
therefore
3.6 with bar over 6
Part 5) Which of the following numbers can be expressed as repeating decimals?
Verify each case

Verify each case
case a) 43 over 9
[tex]\frac{43}{9}= 4.77777...[/tex]
case b) 49 over 9
[tex]\frac{49}{9}= 5.444444...[/tex]
case c) 35 over 9
[tex]\frac{35}{9}= 3.888888...[/tex]
case d) 32 over 9
[tex]\frac{32}{9}= 3.55555...[/tex]
therefore
43 over 9
Part 7)
we know that
1)Benny deposited $92.50 into his account every month for 10 month
so
[tex]\$92.50(10)=\$925.00[/tex]
2) He used $36.50 every month to pay for art lessons
[tex]\$925.00-10(\$36.50)=\$560.00[/tex] -----> total money left in his account after 10 months
3) After 10 months, he used 1 over 2 of the total money left in his account to go to a summer camp for artists
so
[tex](1/2)(\$560)=\$280.00[/tex]
therefore
Benny spent to go to the summer camp $280.00
Part 8)
we know that
1) Mini earned $160 during the summer doing chores
2) She bought 3 dresses worth $12 each using her chore money.
so
[tex]3(\$12)=\$36[/tex]
To find out how much money was left, subtract $36 from the amount earned during the summer doing chores
[tex]\$160-\$36=\$124[/tex]
therefore
$124
Part 9)
we have
1 year=12 months
Let
x ----> the total deductions for the year
we know that
The total deductions for the year is equal to the Ryan's tennis club membership multiplied by the number of a months in a year
so
[tex]x=(-\$11)12=-\$132[/tex]
therefore
(−$11) ⋅ 12
Part 10)
we know that
The total depth of a submarine is 45 ft
[tex]15\%=15/100=0.15[/tex]
15% of 45 ft is
(0.15)(45)=6.75 ft
using proportion
Find out the deep after 4 minutes
Let
x ----> the deep after 4 minutes
[tex]\frac{6.75}{1}\frac{ft}{min}=\frac{x}{4}\frac{ft}{min}\\\\x=6.75(4)\\\\x=27\ ft[/tex]
therefore
-27 ft

The nail must be shorter than 1 3/8 inches in order to fit. Which number below is less than 1 3/8?
Final answer:
1 mm is less than 1 3/8 inches. An inch is 25.4 millimeters, therefore 1 mm is much smaller than 1.375 inches (equivalent to 1 3/8 inches). The correct answer is option (a).
Explanation:
To answer this question, we need to first understand that 1 3/8 inches is a mixed number, meaning it is made up of a whole number and a fraction. In this case, it is 1 plus 3/8 of an inch. We can convert it into a decimal to compare with other measurements easily, and 1 3/8 inches is equal to 1.375 inches. Now we will compare it with the provided options.
1 mm - 1 millimeter is less than 1 3/8 inches because there are 25.4 millimeters in one inch. Therefore, 1 mm is much smaller than 1.375 inches.
So in this scenario, option (a) 1 mm is less than 1 3/8 inches.

you spend?
Answer:
$3.10 per gallon
Step-by-step explanation:
You are trying to find how many dollars per one gallon.
You divide $68.30 by 22 so you can get dollars per one gallon.
68.30 ÷ 22 = 3.10
Therefore it cost $3.10 per gallon you spend.

Final answer:
You spent $3.10 per gallon of gas.
Explanation:
To determine how many dollars per gallon of gas was spent, we can divide the total cost by the number of gallons. The question states that the total cost for 22 gallons of gas is $68.30.
So we perform the following calculation:
Cost per gallon = Total cost / Number of gallons
Cost per gallon = $68.30 / 22 gallons
Now, dividing $68.30 by 22 gives us:
Cost per gallon = $3.10
Therefore, the cost was $3.10 per gallon.

8(2x+3x+2)= -4x+148
Step-by-step explanation:Step 1: Simplify both sides of the equation.
8(2x+3x+2)=−4x+148
(8)(2x)+(8)(3x)+(8)(2)=−4x+148(Distribute)
16x+24x+16=−4x+148
(16x+24x)+(16)=−4x+148(Combine Like Terms)

40x+16=−4x+148
Step 2: Add 4x to both sides.
40x+16+4x=−4x+148+4x
44x+16=148
Step 3: Subtract 16 from both sides.

x=3
answer: x=3
The solution to the equation 8(2x+3x+2) = -4x + 148 is x = 3.
Explanation:To solve the given equation, let's start by simplifying both sides. First, we distribute the 8 to each term within the parentheses on the left hand side of the equation: 8(2x + 3x + 2) = 16x + 24x + 16 = 40x + 16. The equation then reads:
40x + 16 = -4x + 148.
Next, let's bring all terms involving x together on one side of the equation and constants on the other. We have:
40x + 4x = 148 - 16,
which gives us:
44x = 132.
Finally, to isolate x we divide both sides of the equation by 44 and we get:

if angle 1 and angle 2 form a linear pair. if m<1=5x+9 and m<2=3x+11, find the measure of both angles
Answer: [tex]m\angle 1=109\°\\m\angle 2=71\°[/tex]
Step-by-step explanation:
It is important to remember the definition of "Linear pair angles".
By definitiion "Linear pair angles" are two angles which are adjacents and supplementary.
Based on this, we know that the angles [tex]\angle1[/tex] and [tex]\angle2[/tex] are supplementary, which means that they add up to 180 degrees.
So, knowing that:
[tex]m\angle 1=5x+9\\m\angle 2=3x+11[/tex]
We can write the following expression and solve for "x":
[tex](5x+9)+(3x+11)=180\\\\8x=180-20\\\\x=\frac{160}{8}\\\\x=20[/tex]
Therefore, substituting, we get that the measures of the angles [tex]\angle1[/tex] and [tex]\angle2[/tex] are:
[tex]m\angle 1=5(20)+9=109\°\\\\\\m\angle 2=3(20)+11=71\°[/tex]
Measures of both the angles are 109° and 71°. We found the measures of two angles forming a linear pair, then solving the equation 8x + 20 = 180, which gives x = 20. Substituting x finds the angles.
If angle 1 (∡1) and angle 2 (∡2) form a linear pair, their measures add up to 180° because linear pairs are supplementary angles. Given that the measures are m∡1 = 5x + 9 and m∡2 = 3x + 11, we can set up the equation:
5x + 9 + 3x + 11 = 180Combine like terms:
8x + 20 = 180Subtract 20 from both sides:
8x = 160Divide both sides by 8:
x = 20Now, substitute x back into the expressions for
∡1 and ∡2:
Therefore, the measures of the angles are :
∡1 = 109° and ∡2 = 71°.
The length of a rectangle is 6 inches longer than it’s width. The perimeter is 96 inches. Find the dimensions (length and width) is the rectangle
Final answer:
To find the dimensions of the rectangle, we used the perimeter formula and set up equations to solve for the width (21 inches) and length (27 inches), given that the length is 6 inches longer than its width and the perimeter is 96 inches.
Explanation:
To solve for the dimensions of the rectangle when the length is 6 inches longer than its width and the perimeter is 96 inches, we need to set up two equations based on the perimeter formula for a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
Let w represent the width of the rectangle. Then, the length of the rectangle is w + 6 inches. By substituting these into the perimeter formula, we get:
96 = 2(w + 6) + 2w96 = 2w + 12 + 2w96 = 4w + 1284 = 4ww = 21Now that we know the width is 21 inches, we can find the length by adding 6 inches to the width:
Length = Width + 6 = 21 + 6 = 27 inchesTherefore, the dimensions of the rectangle are 27 inches in length and 21 inches in width.
Final answer:
To find the dimensions of the rectangle, we used the perimeter formula and set up equations to solve for the width (21 inches) and length (27 inches), given that the length is 6 inches longer than its width and the perimeter is 96 inches.
Explanation:
To solve for the dimensions of the rectangle when the length is 6 inches longer than its width and the perimeter is 96 inches, we need to set up two equations based on the perimeter formula for a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
Let w represent the width of the rectangle. Then, the length of the rectangle is w + 6 inches. By substituting these into the perimeter formula, we get:
96 = 2(w + 6) + 2w
96 = 2w + 12 + 2w
96 = 4w + 12
84 = 4w
w = 21
Now that we know the width is 21 inches, we can find the length by adding 6 inches to the width:
Length = Width + 6 = 21 + 6 = 27 inches
Therefore, the dimensions of the rectangle are 27 inches in length and 21 inches in width.
Triangle J is shown below. James drew a scaled version of Triangle J using a scale factor of 4 and labeled it
Triangle K
Triangle J
What is the area of Triangle K?
Answer:
160 not 16
Step-by-step explanation:
The area of Triangle K is 4 times the area of Triangle J.
Explanation:The area of Triangle K can be determined by using the scale factor of 4. Since the scale factor determines how lengths are scaled, the area of a figure is scaled by the square of the scale factor. In this case, the scale factor is 4, so the area of Triangle K will be 4 times the area of Triangle J.
Let's say the area of Triangle J is A. Then, the area of Triangle K will be 4A.
Therefore, the area of Triangle K is 4 times the area of Triangle J.

Store B advertises that it is reducing the refrigerator’s price by $150. When Stephanie compares the sale prices of the refrigerator in both stores, she concludes that the sale prices are equal. What is the refrigerator’s original price? Write and solve an equation.
Answer:
150 dollhairs
Step-by-step explanation:
Answer:
Refrigerator’s original price = 1000 $
Step-by-step explanation:
Let the original price of refrigerator be r.
Store A advertises that the refrigerator is on sale for 15% off the original price.
[tex]\texttt{Price of refrigerator in store A = }r-\frac{15}{100}r=0.85r[/tex]
Store B advertises that it is reducing the refrigerator’s price by $150.
Price of refrigerator in store B = r - 150
Stephanie compares the sale prices of the refrigerator in both stores, she concludes that the sale prices are equal
That is
0.85r = r - 150
0.15r = 150
r = 1000$
Refrigerator’s original price = 1000 $

Find Sn for the given arithmetic series.
a1 = 22, d = –8, n = 21
To find Sn for the given arithmetic series with a1 = 22, d = –8, and n = 21, you can use the formula Sn = (n/2)(2a1 + (n - 1)d). Substituting the values into the formula gives Sn = -2418.
Explanation:To find the sum of an arithmetic series, you can use the formula:
Sn = (n/2)(2a1 + (n - 1)d)
where Sn represents the sum of the series, a1 is the first term, d is the common difference, and n is the number of terms.
In this case, a1 = 22, d = -8, and n = 21. Substituting these values into the formula gives:
S21 = (21/2)(2(22) + (21 - 1)(-8)) = (21/2)(44 + 20(-8)) = (21/2)(44 - 160) = (21/2)(-116) = -2418
Therefore, the sum of the arithmetic series is -2418.
Final answer:
The sum of the first 21 terms (Sn) of the arithmetic series with a first term of 22 and a common difference of -8 is -1222.
Explanation:
To find Sn for the given arithmetic series where the first term a1 = 22, the common difference d = –8, and the number of terms n = 21, we can use the formula for the sum of the first n terms of an arithmetic series:
Sn = ½ n (2a1 + (n - 1)d)
Plugging in the given values:
Sn = ½ × 21 (2 × 22 + (21 - 1)× (–8))
Simplify further to find:
Sn = ½ × 21 (44 – 160)
Sn = ½ × 21 × (–116)
Sn = 10.5 × (–116)
Sn = –1222
Thus, the sum of the first 21 terms of the series is –1222.
