Rewrite in simplest terms: 9w-3(-w-8)
Answer:
\(12w+24\)
Step-by-step explanation:
\(9w−3(−w−8)\)
\(9w+(−3)(−w)+(−3)(−8)\)
\(9w+3w+24\)
\((9w+3w)+(24)\)
\(12w+24\)
Hope it is helpful.....In the simplest form we can write the expression as - 12(w + 2).
We have the following expression -
9w - 3(- w - 8)
We have to write it in simplest form.
Expand the following expression -Δ = (x - α)(x - β)Expanding we get -
Δ = x(x - β) - α(x - β)
Δ = \(x^{2}\) - βx - αx + αβ
According to the question, we have -
9w - 3(- w - 8)
Simplifying it, we get -
9w + 3(w + 8)
9w + 3w + 24
12w + 24
12(w + 2)
Hence, in the simplest form we can write the expression as - 12(w + 2).

Make 4 \(\frac{2}{5}\) an improper fraction. To do that multiply the denominator, 5 by 4, which gets you 20. Then add the numerator, 2, to get 22. put the original denominator back into the fraction, and you get \(\frac{22}{5}\) . If you divide that by \(\frac{2}{5}\) , you would get 11 because you divide the numerator and the denominators cancel each other out since they are both the same number, and 22 ÷ 2 = 11.

John has a cookie jar that contains 5 chocolate cookies, and 10 oatmeal cookies. He will draw two cookies from the jar one at a time without replacing the first cookie. What is the probability that John gets a chocolate cookie on his first draw and an oatmeal cookie on his second draw?
Answer:
ughhhhh
Step-by-step explanation:
To calculate the probability of John drawing a chocolate cookie on his first draw and an oatmeal cookie on his second draw without replacement, we need to consider the total number of cookies and the number of favorable outcomes.
Total number of cookies = 5 (chocolate) + 10 (oatmeal) = 15
For the first draw, John has 5 chocolate cookies out of 15 total cookies, so the probability of drawing a chocolate cookie on the first draw is 5/15.
After the first draw, there will be 14 cookies remaining in the jar (4 chocolate and 10 oatmeal).
For the second draw, John wants to draw an oatmeal cookie. Out of the 14 remaining cookies, there are 10 oatmeal cookies. So the probability of drawing an oatmeal cookie on the second draw, given that a chocolate cookie was drawn on the first draw, is 10/14.
To calculate the overall probability, we multiply the probabilities of each individual draw:
Probability = (5/15) * (10/14) = 50/210 = 5/21
Therefore, the probability that John gets a chocolate cookie on his first draw and an oatmeal cookie on his second draw is 5/21.

A cake recipe calls for the following dry ingredients: 3 ½ cups of flour, 2 ⅔ cups of sugar, and 1 ¾ cups of cocoa. To the nearest cup, how much dry ingredients will be used?
The amount of dry ingredients used in the cake recipe is approximately 7 cups.
To find the total amount of dry ingredients used in the cake recipe, we need to add up the amounts of flour, sugar, and cocoa.
3 ½ cups of flour is equal to 3 cups plus 0.5 cups, or 3 cups and 8 ounces.
2 ⅔ cups of sugar is equal to 2 cups plus 0.67 cups, or 2 cups and 10.72 ounces.
1 ¾ cups of cocoa is equal to 1 cup plus 0.75 cups, or 1 cup and 12 ounces.
Adding these amounts together, we get:
3 cups and 8 ounces + 2 cups and 10.72 ounces + 1 cup and 12 ounces = 6 cups and 14.72 ounces
To the nearest cup, this is equal to 7 cups.
Therefore, the amount of dry ingredients used in the cake recipe is approximately 7 cups.

The speed of a passenger train is 8 mph faster than the speed of a freight train. The passenger train travels 280 miles in the same time it takes the freight train to travel 240 miles. Find the speed of each train.
The speed of the freight train is 30 mph, and the speed of the passenger train is 30 + 8 = 38 mph.
We have,
Let's denote the speed of the freight train as x mph.
Since the speed of the passenger train is 8 mph faster, we can denote the speed of the passenger train as (x + 8) mph.
To find the speeds of each train, we can use the formula:
Speed = Distance / Time
For the passenger train: (x + 8) = 280 / t, where t is the time taken to travel 280 miles.
For the freight train: x = 240 / t, where t is the time taken to travel 240 miles.
Since the times taken for both trains are the same, we can set the two equations equal to each other:
(x + 8) = 280 / t = x = 240 / t
Cross-multiplying the equation, we have:
(x + 8) t = x (280 / t)
xt + 8t = 280
xt - x = 240
Simplifying the equation, we get:
xt - x = 240
x(t - 1) = 240
Dividing both sides by (t - 1):
x = 240 / (t - 1)
Substituting the value of x in the first equation:
(x + 8) = 280 / t
240 / (t - 1) + 8 = 280 / t
Simplifying the equation, we get:
240t + 8(t - 1) = 280(t - 1)
240t + 8t - 8 = 280t - 280
248t - 8 = 280t - 280
280 - 8 = 280t - 248t
272 = 32t
t = 272 / 32 = 8.5
Substituting the value of t in the equation for x:
x = 240 / (t - 1) = 240 / (8.5 - 1) = 30
Therefore,
The speed of the freight train is 30 mph, and the speed of the passenger train is 30 + 8 = 38 mph.

The coordinates of the reflected point P' will be (4, -3).
When a point is reflected over the x-axis, its y-coordinate changes sign.
In this case, the point P has coordinates (4,3).
To reflect it over the line x=3, we need to keep its x-coordinate the same and change its y-coordinate to its opposite.
So, the x-coordinate of the reflected point will still be 4, but the y-coordinate will become -3.
Therefore, the coordinates of the reflected point P will be (4, -3).

If you can buy one bunch of seedless green grapes for $2, then how many can you buy with $18?
If you can buy 1 bunch of seedless green grapes for $2, then $18 we can buy 9 bunches.
The concept used here is a simple division to find out how many bunches of seedless green grapes can be purchased with a given amount of money.
In this case, we know the cost of one bunch of seedless green-grapes ($2) and we are given a total amount of money ($18) that we can spend on grapes. We can use division to find out how many bunches we can buy with that amount.
⇒ Number of bunches = ($18)/($2) per bunch,
⇒ Number of bunches = 9 bunches;
Therefore, with $18, you can buy 9 bunches of seedless green grapes.

Answer:
Area is 364
Step-by-step explanation:
A parallelogram's area is equal to base times height. So it doesn't depend on the angle at all, as long as the base and height are constant.
That means that the area of the parallelogram on the left is the same as if it was a rectangle (an extension of the rectangle part on the right).
This brings us to the answer - the area is the same as the area of a 14x26 rectangle.
14*26=364
Alternatively, let's compute the area of the rectangle on the right:
18*14 = 252
And the area of the parallelogram
14 * (26-18) = 14*8 = 112
And the area of the composite figure is 252+112 = 364

Answer:
At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0
Step-by-step explanation:
At midnight, the temperature was 43.7°F. In the morning, the temperature was −3.6°F.
We can say that −3.6 lie on the LHS of a number line while 43.7 lie on RHS of the number line and 0 at the mid.
43.7°F is above 0 and 3.6°F is below 0.
At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0 . Hence, the correct option is (d).
For the question of total area of the cuboid is 200cm^.
I understand where we divide 150 by 4.
But why do I need to multiply by 5, when there are 6 faces.
You need to multiply by 5 instead of 6 because each pair of opposite faces on a cuboid has the same area, so by considering one face from each pair, you ensure that you don't count any face twice.
When calculating the total surface area of a cuboid, you need to understand the concept of face pairs.
A cuboid has six faces, but each face has a pair that is identical in size and shape.
Let's break down the reasoning behind multiplying by 5 instead of 6 in the given scenario.
To find the surface area of a cuboid, you can add up the areas of all its faces.
However, each pair of opposite faces has the same area, so you avoid double-counting by only considering one face from each pair. In this case, you have five pairs of faces:
(1) top and bottom, (2) front and back, (3) left and right, (4) left and back, and (5) right and front.
By multiplying the average area of a pair of faces by 5, you account for all the distinct face pairs.
Essentially, you are considering one face from each pair and then summing their areas.
Since all the pairs have the same area, multiplying the average area by 5 gives you the total surface area.
When dividing 150 by 4 (to find the average area of a pair of faces), you are essentially finding the area of a single face.
Then, by multiplying this average area by 5, you ensure that you account for all five pairs of faces, providing the total surface area of the cuboid.
Thus, multiplying by 5 is necessary to correctly calculate the total surface area of the cuboid by accounting for the face pairs while avoiding double-counting.
