therefore, he drove 60.5 mph

Answer:

The number is -1.

Step-by-step explanation:

Let the number be represented by n.

Then "9 is added to twice a number and this sum is multiplied by 6" is represented by 2n + 9, and

" the number is multiplied by 7 and 14 is added to the product" is

7n + 14.

Then the complete equation is 2n + 9 = 7n + 14.

We must solve this for n.  To accomplish this, subtract 2n from both sides, obtaining 9 = 5n + 14.  Then subtract 14 from both sides, obtaining

-5 = 5n.  Then n must be -1.

Answer:

D) |x| = a and |y| = b

Step-by-step explanation:

Given the numbers x = a and y = –b

Absolute function always gives the output as a positive number

Absolute function of |-x|= x

For example |5|= 5  and |-5| = 5

Given x=a

|x| = |a| = a, so |x| = a

Given y=-b

|y| = |-b| = b , so |y| = b

Hence, |x| = a and |y| = b

Answer:

Step-by-step explanation:

An estimate is usually a guess, but I somehow think that's not what you want.

She starts with 4 2/3 cups of batter. When she divides it into two, one of the batters has 2 1/4 cups. That's the one she puts blueberries in.

The other batter is the one you are interested in. How big is it?

Estimate: One

The estimated size would be 4 2/3 - 2 1/3 = 2 1/3 which is an estimate. It is just taking the closest number to use so you don't have to grab your calculator.

Actual Size: Two

4 2/3 - 2 1/4 is the size of the second batter. Since 2/3 is greater than 1/4 you need only subtract the whole numbers and then the fractions.

Whole number subtraction: 4 - 2 = 2

Fraction subtraction: 2/3 - 1/4

Find the Lowest common multiple between 3 and 4: It is 12. 3 and 4 are prime to each other. They have nothing in common.

So the actual size of the batter containing the walnuts is 2 5/12

81[tex]w^{4}[/tex] - 16 ← is a difference of squares

• a² - b² = (a - b)(a + b)

81[tex]w^{4}[/tex] = (9w²)² → a = 9w² and 16 = 4² → b = 4

= 3z(9w² - 4)(9w² + 4)

9w² - 4 ← is also a difference of squares with a = 3w and b = 2

= 3z(3w - 2)(3w + 2)(9[tex]w^{4}[/tex] + 4)

Answer:

1.  A = 59

2.  A = 43

Step-by-step explanation:

If we have a right triangle  we can use sin, cos and tan.

sin = opp/ hypotenuse

cos= adjacent/ hypotenuse

tan = opposite/ adjacent

For the first problem, we know the opposite and adjacent sides to angle A

tan A = opposite/ adjacent

tan A = 8.8 / 5.2

Take the inverse of each side

tan ^-1 tan A = tan ^-1 (8.8/5.2)

A = 59.42077313

To the nearest degree

A = 59 degrees

For the second problem, we know the  adjacent side and the hypotenuse to angle A

cos A = adjacent/hypotenuse

cos A = 15.3/21

Take the inverse of each side

cos ^-1 cos A = cos ^-1 (15.3/21)

A = 43.23323481

To the nearest degree

A = 43 degrees

Answer:

G(-1, 3)

Step-by-step explanation:

You need to try each point in the given equation to see which one does not work.

The definition of the function is that it has two different expressions. The upper expression is used for values of x that are less than or equal to -1.

For values of x less than or equal to -1, the expression is f(x) = 2x + 3.

Look at point F. Its x-coordinate is -1.5. Since -1.5 is less than or equal to -1, use the upper expression. Plug in -1.5 for x and find f(-1.5).

f(x) = 2x + 3

f(-1.5) = 2(-1.5) + 3 = -3 + 3 = 0

That gives point (-1.5, 0), so point F is on the graph of f(x).

Now let's look at point G(-1, 3). For point G, x is -1. Since -1 is also less than or equal to -1, you still use the upper expression for x = -1.

f(x) = 2x + 3

f(-1) = 2(-1) + 3 = -2 + 3 = 1

The point that contains x-coordinate -1 is point (-1, 1). Point G is (-1, 3), so point G is not on the graph of function f.

You already know the answer is point G, but let's continue to show how the other two points are part of the graph of the function.

Point H is (0, 4). For this point, the x-coordinate is 0. The lower expression is used for x greater than -1, and 0 is greater than -1, so you must use the second expression. Now we evaluate the function at x = 0 using the second expression.

f(x) = 4 + x

f(0) = 4 + 0 = 4

giving us point (0, 4).

Point H is (0, 4), so point H is on the graph of the function.

Now we do point J(4, 8). Like for point H, the x-coordinate of point H is greater than -1, so you use the second expression.

f(x) = 4 + x

f(4) = 4 + 4 = 8

giving point (4, 8).

Point J is (4, 8), so it is on the graph.

The only point not on the graph is point G.

Answer: C. 45

Step-by-step explanation:

1. You know that there are 6 tulips for every 9 daisies. Then, if there are 30 tulips, you can write the following expresion, where [tex]x[/tex] is the number of daisies when there are 30 tulips:

[tex]\frac{6}{9}=\frac{30}{x}[/tex]

2. Then, you must solve for x as following:

[tex]6x=30*9\\6x=270\\x=\frac{270}{6}\\x=45[/tex]

3. Therefore, the answer is 45 daisies.

By creating and solving a ratio based on the given relationship of 6 tulips to 9 daisies, it is determined that if there are 30 tulips, there must be 45 daisies in the flower garden. Thus, the correct choice to the student's question is option C) 45 daisies.

To solve this problem, we can set up a ratio based on the information given: there are 6 tulips for every 9 daisies. The ratio of tulips to daisies is therefore 6:9. If there are 30 tulips, this ratio must be multiplied by a certain factor to reach 30. To find this factor, we divide 30 (the actual number of tulips) by 6 (the number of tulips in the ratio), giving us a factor of 5. We then multiply the daisy part of the ratio (9) by 5 to find the actual number of daisies.

6 tulips : 9 daisies = 30 tulips : x daisies
30 / 6 = 5
9 daisies * 5 = 45 daisies

Therefore, if there are 30 tulips in the garden, there are 45 daisies, which corresponds to choice C.

Answer:CD

Step-by-step explanation:

There is a line from A-B and the fastest way to get there is to go "down" c

Answer: The answer is (A) CD.

Step-by-step explanation: We are given to choose the correct option that represents the distance from point D to AB.

We know that the distance between a point and a line is the length of the perpendicular drawn from the point to the line.

So, here CD will be the required distance from point D to AB, because CD is perpendicular from point D to AB.

Thus, (A) is the correct option.

Step-by-step explanation:

1. Assuming the expression is:

[tex]3 \cdot \sqrt{22} \cdot \sqrt{58} \cdot \sqrt{18}[/tex]

Express the radicands as multiplication of prime numbers:

[tex]3 \cdot \sqrt{11 \cdot 2} \cdot \sqrt{2 \cdot 29} \cdot \sqrt{3^2 \cdot 2}[/tex]

Distribute the radicals over the multiplication where a power is present:

[tex]3 \cdot \sqrt{11 \cdot 2} \cdot \sqrt{2 \cdot 29} \cdot \sqrt{3^2} \cdot \sqrt{2}[/tex]

[tex]3 \cdot \sqrt{11 \cdot 2} \cdot \sqrt{2 \cdot 29} \cdot 3 \cdot \sqrt{2}[/tex]

[tex]9 \cdot \sqrt{11 \cdot 2} \cdot \sqrt{2 \cdot 29} \cdot \sqrt{2}[/tex]

Apply the inverse of distributive property of radicals over multiplication:

[tex]9 \cdot \sqrt{11 \cdot 2 \cdot 2 \cdot 29\cdot 2}[/tex]

[tex]9 \cdot \sqrt{11 \cdot 2^2 \cdot 29\cdot 2}[/tex]

[tex]9 \cdot \sqrt{11 \cdot 29\cdot 2} \cdot \sqrt{2^2} [/tex]

[tex]9 \cdot \sqrt{638} \cdot 2 [/tex]

[tex]18 \cdot \sqrt{638}[/tex]

2. Assuming the expression is:

[tex](2 x^4 y^{-3})^{-1}[/tex]

Distribute the exponent over the multiplication

[tex]2^{-1} \cdot {(x^4)}^{-1} \cdot {(y^{-3})}^{-1}[/tex]

[tex]\frac{1}{2} \cdot x^{-4} \cdot y^{3}[/tex]

[tex]\frac{1}{2} \cdot \frac{1}{x^4} \cdot y^{3}[/tex]

[tex]\frac{y^{3}}{2 x^4}[/tex]

3. Assuming the expression is:

[tex]\frac{2 x^4y^{-4}z^{-3}}{3 x^2 y^{-3} z^4}[/tex]

Group by similar terms and simplify:

[tex]\frac{2}{3} \cdot \frac{x^4}{x^2} \cdot \frac{y^{-4}}{y^{-3}} \cdot \frac{z^{-3}}{z^4}[/tex]

[tex]\frac{2}{3} \cdot x^2 \cdot y^{-1} \cdot z^{-7}[/tex]

[tex]\frac{2 x^2}{3 y z^{-7}} [/tex]

Answer:

Step-by-step explanation:

The table tells you that for every 1 package, you have 16 tortillas. Thus, the function is y = 16x.

y = amount of tortillas and x = number of packages

To find the number of packages for 64 tortillas, divide 64 by 16-- which gives you 4. Instead of "3" packages, change that number to "4".

To find the amount of tortillas in 8 packages, multiply 8 by 16-- which gives you 128 tortillas. Instead of "46", replace that amount with 128.

Divide 144 tortillas by 16, which gives you 9. The answer you gave is correct.

Multiply 10 packages by 16, which gives you 160-- your answer is also correct here.

Final answer:

After evaluating each set of points for the inequality y ≤ 8x – 3, it is found that set C satisfies the inequality for all its points, making it the correct set of points containing the solutions to the inequality.

Explanation:

The student's question is related to solving a linear inequality, specifically finding which set of points satisfies the inequality y ≤ 8x – 3.

To find the correct set of points that contain the solutions to this inequality, we must check each pair of (x, y) coordinates provided in the options. A coordinate pair is a solution to the inequality if substituting the x and y value into the inequality makes it a true statement.

B. {(3,22), (2,3), (8,27)}

C. {(4,29), (–6,–58), (7,19)}

Answer:

Total bill including the tip = $156.86  .

Step-by-step explanation:

Given:Bill at a restaurant came to $136.40 the patrons decide to leave a 15% tip .

To find:  What is the total bill including the tip.

Solution: we have given that

A restaurant bill came = $136.40 .

Tip percentage = 15% of bill

Tip cost = 15% of $136.40 .

Tip cost = $20.46 .

So, total bill including the tip = $136.40 + tip cost

                                                 = $136.40 + $20.46

                                                  = $156.86 .

Therefore , Total bill including the tip = $156.86  .

The ratios 8/7 and 9/7 are not equivalent. Using cross multiplication, we find that the cross products are different, signaling that these two ratios are not equivalent.

To determine whether the ratios 8/7 and 9/7 are equivalent, we can cross multiply. In this case, if the two products are equal then the ratios would be equivalent.

Cross multiplication is a method used to test if two ratios are equivalent. It involves multiplying the numerator of the first fraction by the denominator of the second fraction and comparing that product with the product of the denominator of the first fraction and the numerator of the second fraction. If the two products are equal, then the two fractions are equivalent.

Using this method, the cross products of the ratios 8/7 and 9/7 are (8 * 7) and (9 * 7), which are 56 and 63, respectively. Since these two products are not equal, the two ratios are not equivalent.

Since we are given that l and m are parallel, we can use the property of alternate exterior angles.

This property states that when two lines are cut by a transversal, the alternate exterior angles are congruent.

In the diagram, we see that ∠A and 2x+15 ∘  are alternate exterior angles. Therefore, we have:  

∠A=2x+15 ∘

We are also given that ∠A=75 ∘ .

Substituting this value into the equation above, we get:

75 ∘ =2x+15 ∘

Solving for x, we get:

2x=75 −15 ∘

2x=60 ∘

x= 60/2 ∘

x=30∘

Therefore, the value of x is 30 ∘ .
