7 (5x +  10) - 10x

7*5x + 7*10 - 10x

35x + 70 - 10x

25x + 70

Answer:  25x + 70

Answer:

Step-by-step explanation:

There is  a point V with ration 6 to 2, therefore we must find the coordinates of point V and the distance from A to V

According to the graph

[tex]c^{2}=x^{2}+y^{2}\\c^{2}=8^{2}+4^{2}\\c=\sqrt{64+16}=8.9.4\\sin\alpha =\frac{4}{8.94}[/tex]

α≅27°

V=2*8.94/6 (ratio 6:2)

V=2.98mile

[tex]sin27=\frac{y}{2.98}\\y=sin27*2.98=1.35\\cos27=\frac{x}{2.98}\\x=cos27*2.98=2.65[/tex]

coordinates of V = (2,65;1.35)

Distance from A to V

[tex]d_{AV}=2.98 miles[/tex]

finally

Mary's mistake is to take the 6 to 2 ratio as the distance traveled from the globe only in the x direction

[tex]\large\boxed{25\%}[/tex]

Assuming that all the sections are the same size, there are four sections of equal size.

Blue would be one out of those four sections, so the probability is 1/4. In decimal form this is .25, and as a percent this is 25%.

Hope this helps!

The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue , 1 red , and 1 orange section is 1/4.

The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue, 1 red, and 1 orange section is 1/4 or 25%.

Total = 1+1+1+1 = 4

Number of blue =1

Therefore, probability =1/4

Answer:

(c)t=p+5

Step-by-step explanation:

total price= item price + gift wrapping cost (given)

gift wrapping cost is constant/unchanged= 5

total price= t

item price=p

therefore by derivation t=p+5 (option c)

Final answer:

The correct equation to represent the store's $5 gift wrapping fee added to the price of an item is C. t = p + 5, where p is the price of the item and t is the total cost with gift wrapping.

Explanation:

The question is asking to find an equation that shows the relationship between the price of an item, represented by p, and its total cost with gift wrapping, represented by t. Given that the store adds a $5 fee for gift wrapping, the correct equation needs to include the original price of the item and the additional gift wrapping fee. Therefore, the total cost t is equal to the price of the item p plus the $5 wrapping fee.

The correct equation representing this situation is C. t = p + 5.

This is because when you start with the initial price of an item p and add a fixed gift wrapping fee of $5, you get the total cost t. It is the sum of the two values: the price of the item plus the additional fixed fee for gift wrapping.

[tex]\large \boxed{\text{D. 126.2 cm}^{2}}[/tex]

Step-by-step explanation:

The area left over for scrap is the area of the circle minus the area of the hexagon.

1. Area of circle

The formula for the area of a circle is

A = πr²

A = π(6)² =  36π = 113.1 in²

2. Area of hexagon

A hexagon consists of six equilateral triangles, each of side a, and we can divide each of them into two right triangles.

So, we can calculate the area of one right triangle and multiply by 12.

The formula for the area of one triangle is

A = ½bh

(a) Height of a small triangle

Per the Pythagorean Theorem,

[tex]\begin{array}{rcr}h^{2} + 3^{2} & = & 6^{2}\\h^{2} + 9 & = & 36\\h^{2} & = & 27\\& = & 3\sqrt{3}\\\end{array}\\[/tex]

(b) Area of a small triangle

A = ½ bh = ½ × 3 × 3√3 = 4.5√3 in²

(c) Area of the hexagon

The hexagon contains 12 small triangles.

A = 12 × 4.5√ 3 = 54√3 ≈ 93.53 in²

3. Area of scrap

A ≈ 113.1 in² - 93.53 in² = 19.6 in²

[tex]A = \text{19.6 in}^{2} \times \left(\dfrac{\text{2.54 cm}}{\text{1 in}}\right )^{2} = \text{126.2 cm}^{2}\\\\\text{The area of the scrap is $\large \boxed{\textbf{126.2 cm}^{\mathbf{2}}}$}[/tex]

Final answer:

Jodie used 2 pints of liquid for her experiment, as she poured 2 cups each of water and milk and there are 2 cups in 1 pint.

Explanation:

Jodie used 4 cups of liquid for her experiment, with 2 cups of water and 2 cups of milk. To convert cups into pints, we use the conversion rate: 1 pint = 2 cups. Therefore, Jodie has used a total of 2 pints of liquid in her experiment (since 4 cups divided by 2 cups per pint equals 2 pints). This demonstrates understanding of volume, which is the amount of space a substance (such as a liquid) occupies and is typically measured in liters, but in this case, we are using pints as a unit of measure.

Answer:

(-11, 3)

Step-by-step explanation:

When you move -8 to the left its on the x-axis and it's on the negative side. Moving it to the left would mean the number is lower than -8. Moving it to the left 3 units would mean its -11. When you move -1 up 4 units it's on the y axis on the negative side in the beginning. Moving it up would mean the number is higher than -1. Moving -1 up 4 units would mean its 3.

A translation moves a point a constant distance in a given direction. Given the point (-8,-1), if it is translated left 3 units and up 4 units, the new point, or image point, is (-11,3).

In mathematics, a translation refers to a geometric transformation that moves every point a constant distance in a specific direction. In this instance, the point (-8,-1) is being moved left 3 units and up 4 units. To implement this translation, you subtract 3 from the x-coordinate and add 4 to the y-coordinate.

So, start with the original point (-8,-1). Subtract 3 from the x-coordinate which gives you -8 - 3 = -11. Then, add 4 to the y-coordinate which gives you -1 + 4 = 3. After the translation, your new point, or image point, is (-11,3).

[tex]P = 50 + 0.68(50) = 50 + 34 = 84[/tex]

84% probability of a meerkat living less than 14.6.

A similar problem is given at https://brainly.com/question/13503878

To estimate the probability of a meerkat living less than 14.6 years, we can use the empirical rule which states that approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

To estimate the probability of a meerkat living less than 14.6 years, we can use the empirical rule which states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

Given that the average lifespan is 13.1 years and the standard deviation is 1.5 years, we can calculate the z-score for 14.6 years using the formula:

z = (x - μ) / σ

where x is the value we want to find the probability for (14.6 years), μ is the mean (13.1 years), and σ is the standard deviation (1.5 years).

Substituting the values, we get:

z = (14.6 - 13.1) / 1.5 = 1.0

Now we can look up the probability corresponding to a z-score of 1.0 in a standard normal distribution table, which is approximately 0.8413. This means that the probability of a meerkat living less than 14.6 years is about 0.8413 or 84.13%.

Answer:

-12/3

Step-by-step explanation:

Answer:An odd number of factors were negative.

it is this because

-3 x -3 x -3 x 3 =-81

-81 x -2= 162

you basically want to end up with a negative number so the -2 will change it back into a positive value.

hope this helps :D

It would be C. An odd number of factors were negative.

We can start off by eliminating A. If all of the numbers were positive: 1 x 2 x 3 x 4 = 24, and 24 ÷ - 2  = -12, since you are still dividing a positive by a negative.

With B- Both problems have you multiplying negative numbers by each other until they cancel out. In B, if you multiply -1 x -2, the negatives cancel out and you get 2. and then, -3 x -4 = 12, negatives cancelling out again, and your last two numbers are going to be positive, so once you multiply them together and multiply by a negative your result will be negative.

D is similar to B. Since we have 4 numbers, two will have to be negative. -1 x 2 x -3 x 4 = 24 since the two negatives will cancel each other out.

the answer is C. An odd number of factors were negative then, since if we have 1 or 3 negative numbers, there will be one left over after the others cancel each other out.

Step-by-step explanation:

When the number of hours increases, the number of miles increases

When the number of hours increases, the number of miles increases.

The rate of change of position of an object in any direction is called as Speed.

As the number of hours changes then the number of miles traveled by the car will be also changed.

Such that number of miles traveled by the car  increases then the  number of hours also increases.

The reason behind this is, the car is traveling at a constant speed of 65 miles per hour, which means it travels longer as the distance is more.

If the number of hours decreases, the number of miles traveled by the car will also decrease by converse, since the car has had little time to cover distance.

Therefore, When the number of hours increases, the number of miles increases.
