Answer:

8 grape and 16 cranberry

Step-by-step explanation:

To find this, we need to know what one-third of 24 boxes are; we'd then do 24 divided by 3, which is equal to 8. One-third of them were grape so we know 8 are grape. Cranberry makes up the other two-thirds; two-thirds is equal to one-third times 2. 8 (one-third) times 2 is 16, giving our answer of 16 cranberry.

Answer:

mr peterson bought 8 boxes of grape juice and he bought 16 boxes of cranberry juice

Rate of change of a function

1. From x = 1 to x = 4

2. From x = 5 to x =8

Then,

Rate of change for first condition

∆x/∆t = (x2-x1) / (t2-t1)

∆x/∆t = (4-1) / (t2-t1)

∆x/∆t = 3 / (t2-t1)

Rate of change for second condition

∆x/∆t = (x2-x1) / (t2-t1)

∆x/∆t = (8-5) / (t2-t1)

∆x/∆t = 3 / (t2-t1)

The rate of change are equal, it shows that the slope are equal.

So, it is a straight line function.

Since it has equal rate of change..

Answer:

Step-by-step explanation:

Given:

250 students And respective percentage of students who are having dogs and cats.

To Find:

60% said that they have a cat. Of the students who have a cat, 70% also have a dog. Of the students who do not have a cat, 75% have a dog

Solution:

Taking each condition as follows:

60% of 250 have cats

i.e   0.6 *250= 150 students have cats

So 150 students of that 70% has dogs

i.e 0.7*150=15*7=105 students have dogs

Now 40 % of 250 dont have cats

i.e  0.4*250=100 students dont have cats

So  Of which 75 % have dogs

i.e 0.75*100= 75 students will have dogs.

Answer:

Mme Q spent more time answering emails from students by 10 minutes

Step-by-step explanation:

Here we have

Time spent by Mme Q in answering mails on Friday given by

5/6 Hour = 50 minutes and

7/12 Hour = 35 minutes

Total time spent on Friday = 85 Minutes or

5/6 + 7/12 = 17/12 Hours

Time spent by Mme F in answering mails on Friday given by

1/2 Hour = 30 minutes and

3/4 Hour = 45 minutes

Total time spent on Friday by Mme F = 75 Minutes or

1/2 + 3/4 = 5/4 Hours

Therefore, Mme Q spent more time answering emails from students by 85 - 75 = 10 minutes.

-3 = 2 + b

-2   -2

 -1 = b

3.) Equation

y = 2/3x - 1

Write an inequality

Since y must be below the line, that means y is less than the equation used to find the line.

y < 2/3x - 1

Answer: He is able to carry 40 letters

Step-by-step explanation: The total weight the mail carrier is allowed is 30 pounds, whereas each letter weighs 12 ounces.

What we need to do is simply find the rate of conversion between an ounce and a pound.

By conversion, 1 ounce equals 0.0625 pounds, that is;

1 ounce = 0.0625 pounds

Therefore 12 ounces would be 0.0625 times 12 which equals, 0.75 pounds. This means one letter weighs an equivalent of 0.75 pounds. If the mail carrier is allowed to carry a total of 30 pounds, then he can carry;

No of letters = Total weight allowed/weight of one letter

No of letters - 30/0.75

No of letters = 40

Hence the mail carrier is able to carry 40 letters.

Your Answer is C. He can carry 40 letters.

Answer: [tex]BC=14.8[/tex]

Step-by-step explanation:

By definition, an Isosceles triangle has two equal sides and its opposite angles are congruent.

Observe the figure attached, where the isosceles triangle is divided into two equal right triangles.

So, in this case you need to use the following Trigonometric Identity:

[tex]sin\alpha =\frac{opposite}{hypotenuse}[/tex]

In this case, you can identify that:

[tex]\alpha =\angle BAD=\angle CAD=18\°\\\\opposite=BD=CD=x\\\\hypotenuse=AB=AC=24[/tex]

Substituting values, and solving for "x", you get:

[tex]sin(18\°)=\frac{x}{24}\\\\24*sin(18\°)=x\\\\x=7.416[/tex]

Therefore, the length of BC rounded to nearest tenth, is:

[tex]BC=2(7.416)=14.8[/tex]

20% of a = 11

[tex]\frac{20}{100}[/tex] a = 11

[tex]\frac{1}{5}[/tex] a = 11

a = 55

I hope this helps! If you have any questions, feel free to ask.

Answer.

2.2

Why:

in percents you always put the percent above 100% ( so it'll look like this---- 20/100) and your number that is left out would be 11 so you put it by your percent like this----20         a

                               100        11

so now you do divide and multiply: you divide 20 by 100 and multiply by 11 to get a which is 2.2

Answer:

Angle E should be 105 degrees.

Step-by-step explanation:

Since a triangle equals 180, you subtract 47° and 28° from that and come up with 105°.

The angle E is 105 degrees when  Angle D is 28 degrees. Angle F is 47 degrees.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Let the triangle be DEF.

Angle D is 28 degrees. Angle F is 47 degrees.

We need to find the angle E

By angle sum property we know the sum of three angles of a triangle is 180 degrees.

28+47+x=180

75+x=180

Subtract 75 from both sides

x=180-75

x=105 degrees.

Hence, the angle E is 105 degrees when  Angle D is 28 degrees. Angle F is 47 degrees.

Step-by-step explanation:

The correct statement about histograms is that data is organized in equal intervals. A histogram represents data through bars of different heights, corresponding to their frequency, grouped into specified ranges.

In regards to histograms in mathematics, the true statement is: C. Data is organized in equal intervals. A histogram is a type of graphical representation that organizes a group of data points into a specified range. The data is portrayed via bars of different heights, where each bar groups numbers into ranges. These bars touch each other where the height of each bar corresponds to its frequency of data points. Unlike bar charts, histograms do not display data in separate categories, but as continuous data grouped into ranges, hence they are arranged in equal intervals.

Answer:

Step-by-step explanation:

A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A linear equation is special because: It has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction

The given equation y = x² - 1 is not a linear equation.

Linear equations are algebraic equations that have only one constant and are only of the first degree.

We know that linear equations are of the only first-order(linear) term, but since the given equation has the second-order(linear) term.

Hence, the given equation y = x² - 1 is not a linear equation.

To find the probability of getting all 4 cards that are queens, we calculate the number of favorable outcomes and the total number of possible outcomes. The probability is the number of favorable outcomes divided by the total number of possible outcomes.

To find the probability of getting all 4 cards that are queens, we need to calculate the number of favorable outcomes (4 queens) and the total number of possible outcomes when 4 cards are dealt from a shuffled deck of 52 cards.

The total number of possible outcomes can be calculated using combinations. We can use the formula C(n, r) = n! / (r!(n-r)!), where n is the total number of items (52 cards) and r is the number of items to be selected (4 cards). So, C(52,4) = 52! / (4!(52-4)!) = 270,725.

The number of favorable outcomes is 4 since we want all 4 cards to be queens.

Therefore, the probability is the number of favorable outcomes divided by the total number of possible outcomes: P(all 4 cards are queens) = 4/270,725 = 0.00001475 (rounded to 5 decimal places) or approximately 0.0015%.
