[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]

3. If Z=8, then [tex]N=2\cdot 8-11=16-11=5[/tex]

4. If Z=9, then [tex]N=2\cdot 9-11=18-11=7[/tex]

Thus, four other possibilities are

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.

Don't forget to rate as Brainliest

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.

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 $

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:

Combine like terms:

Subtract 20 from both sides:

Divide both sides by 8:

Now, substitute x back into the expressions for
∡1 and ∡2:

Therefore, the measures of the angles are :
∡1 = 109° and ∡2 = 71°.

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

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.

44x+16−16=148−16

44x=132

Step 4: Divide both sides by 44.

44x

44

=

132

44

x=3

answer: x=3

The solution to the equation 8(2x+3x+2) = -4x + 148 is x = 3.

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:

x = 3

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]

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

Answer:

160 not 16

Step-by-step explanation:

The area of Triangle K is 4 times the area of Triangle J.

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.

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.

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.

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.
