In a class, every student knows French or German (or both). 15 students know French, and 17 students know German.
What is the largest possible number of students in that class?

PLZ ANSWER AND SHOW WORK?

Answers

Answer:
32 students

Explanation:
We are given that:
Students in the class can either speak French, German or both
15 students know French
17 students know German

Now, the maximum number in the class can be calculated by assuming that no student can speak both languages.
This means that the number of students will be the summation of those who know French only (15) and those who know German only (17)

In this case:
the maximum number of students = 15 + 17 = 32 students

A recent survey of 2500 seventh graders from across the state shows 2 out of 5 of them do not eat breakfast. How many of the students surveyed do not eat breakfast?

Answers

Out of the 2500 seventh graders surveyed, 1000 of them do not eat breakfast, based on the proportion of 2 out of 5.

To find out how many seventh graders surveyed do not eat breakfast, we can use the proportion of students who do not eat breakfast from the survey results.

Given:

- Total number of seventh graders surveyed: 2500

- Proportion of seventh graders who do not eat breakfast: [tex]$ \frac{2}{5} $[/tex]

To find the number of seventh graders who do not eat breakfast, we multiply the total number of seventh graders surveyed by the proportion who do not eat breakfast:

[tex]\[ \text{Number of students not eating breakfast} = \frac{2}{5} \times 2500 \]\[ \text{Number of students not eating breakfast} = \frac{2 \times 2500}{5} \]\[ \text{Number of students not eating breakfast} = \frac{5000}{5} \]\[ \text{Number of students not eating breakfast} = 1000 \][/tex]

Therefore, out of the 2500 seventh graders surveyed, 1000 of them do not eat breakfast.

when 6 less than 3 lots of a number is doubled the result is 18

Answers

this one is a tuff one:((

The unknown number is 5.

Let's represent the unknown number as "x."

The statement "6 less than 3 lots of a number" can be written as 3x - 6.

The next part of the statement is "doubled the result is 18," which translates to 2 * (3x - 6) = 18.

Now, we can solve for "x" using the equation:

2 * (3x - 6) = 18

Expand the expression on the left side:

6x - 12 = 18

Next, isolate "6x" by adding 12 to both sides:

6x = 18 + 12

6x = 30

Now, solve for "x" by dividing both sides by 6:

x = 30 / 6

x = 5

Therefore, the unknown number is 5.

To verify:

"6 less than 3 lots of 5" is (3 * 5) - 6 = 15 - 6 = 9.

"Double the result" of 9 is 2 * 9 = 18, which matches the given result. Hence, the solution is correct.

The green peppers do for the first one because that fraction is larger. The second one is the green paint jar because it is only half while the other is more than half. She uses more flour because it is the larger fraction. And the last one you should explain.

2. The answer is green peppers, because 5/8 is greater than 2/8.

3. The answer is the green paint jar, because 4/8 is less than 4/6.

4. The answer is flour, because 2/3 is greater than 1/3.

5. You need to give an explanation for how you compare the fractions. Here, you make both denominators (bottom numbers) the least common denominator by multiplying the first fraction by 4/4 and the second by 3/3, which gives you 20/24 and 15/24. Now that they are the same, you can ignore the denominators. 20 is clearly greater than 15.

write the function:
[tex]f(x) = - 5 {x}^{2} - 60x - 181[/tex]
in vertex form, and identity its vertex

Answers

Notice that our function [tex]f(x)[/tex] is a parabola, and the vertex form of a parabola is:[tex]f(x)=a(x-h)^{2} +k[/tex] where (h,k) are the coordinates of its vertex.
The first thing we need to do is find the vertex (h,k) and to do that we are going to use the vertex formula: [tex]h= \frac{-b}{2a} [/tex], and then we are going to evaluate our function at [tex]h[/tex] to find [tex]k[/tex].
We know for our problem that [tex]a=-5[/tex], and [tex]b=-60[/tex], so lets replace those values in our vertex formula to find [tex]h[/tex]:
[tex]h= \frac{-b}{2a} [/tex]
[tex]h= \frac{-(-60)}{2(-5)} [/tex]
[tex]h= \frac{60}{-10} [/tex]
[tex]h=-6[/tex]
Now, we are going to evaluate our function at -6 to find [tex]k[/tex]:
[tex]k=f(-6)=-5(-6)^{2} -60(-6)-181[/tex]
[tex]k=-180+360-181[/tex]
[tex]k=-1[/tex]

Now that we have our vertex, where [tex]h=-6[/tex] and [tex]k=-1[/tex]; lets replace those values in our vertex form equation:
[tex]f(x)=-5[x-(-6)]^{2} +(-1)[/tex]
[tex]f(x)=-5(x+6)^{2} -1[/tex]

We can conclude that the vertex form of our function is [tex]f(x)=-5(x+6)^{2} -1[/tex], and its vertex is (-6,-1).

A.Multiply both sides of the equation by 3/4
B.Divide both sides of the equation by 4/3
C.Distribute 3/4 over (x - 8)
D.Distribute 4/3 over (x - 8)

Answers

The answer is C.

The first step in a math problem with distribution involved is to take care of the parentheses (PEMDAS). This means you have to distribute 3/4 to the (x - 8).

I hope this helped!

Answer:

C. Distribute 3/4 over (x - 8)

Step-by-step explanation:

There are multiple ways to begin solving this problem.

If we want to cancel the 3/4 without using the distributive property, we would divide both sides by 3/4. Dividing by 4/3 will not cancel it.

When dividing by fractions, we multiply by the reciprocal; this would be multiplying both sides by 4/3. Multiplying by 3/4 will not cancel it.

Using the distributive property, we multiply (x-8) by the number in front of parentheses, 3/4. We cannot distribute 4/3, since it is not part of the equation.

Answers

Hello,

To find the scale factor, we need to determine how the points are changing.

Point A is changing from (5, 3) to (1.25, 0.75). Therefore, we can write the following two equations using K as the scale factor.

5k = 1.25 or 3K = 0.75

Solving either equation will give you a scale factor of 0.25.

The table shows the electric current produced by a solar cell in different amounts of sunlight (light intensity). Answer the questions using the data. I only need help on 5 and 6

Answers

Answer: In the absence of light, you could predict the current to be 0. This makes sense, because if there is no light then the solar cell won't work. Also, you can see that the data is heading towards 0.

When the light intensity is 1000, you could predict the current to be at about 100. Following the pattern in the data, it seems like you divide the light intensity by 10 to get the current. You could also graph the points.

Final answer:

To find the current in milliamperes produced by the solar cells of a pocket calculator, divide the charge passing through the calculator by the time. In this case, the current is 0.00111 milliamperes.

Explanation:

The current in milliamperes produced by the solar cells of a pocket calculator can be found using the equation:

Current (in mA) = Charge (in C) / Time (in s)

In this case, the charge passing through the calculator is given as 4.00 C and the time is given as 4.00 h (which can be converted to seconds by multiplying by 3600). Substitute these values into the equation to find the current.

Current = 4.00 C / (4.00 h * 3600 s/h) = 0.00111 mA

A circular sinkhole has a circumference of 75.35 meter. A week later, it has a circumference of 150.42 meters.

b,) How many times greater is the diameter of sinkhole now compared to the previous week?

Please explain your anwser ( i didn't understand the part about EACH WEEK)
Thanks in advance!

Answers

we know that
[the length of a circumference is]=2*pi*r
r=[length of a circumference]/(2*pi)

Part a)
a.) Estimate the diameter of the sinkhole each week

Let
first week----------> previous week
second week-----> actual week (now)

for the first week
length=75.35 m
r=75.35/(2*pi)---------> r1=12 m
Diameter=2*r---------> D1=2*12---------> D1=24 m

for the second week
length=150.42 m
r=150.42/(2*pi)---------> r2=23.95 m
Diameter=2*r---------> D2=2*23.95---------> D2=47.90 m

Part b)
b,) How many times greater is the diameter of sinkhole now compared to the previous week?
[diameter of sinkhole now compared to the previous week]=D2/D1
= 47.9/23.95----------> 2

the answer Part b)
the diameter of sinkhole now compared to the previous week is 2 times greater

Final answer:

Using the circumference formula, the estimated diameters of the sinkhole are approximately 24 meters for the first week and 48 meters for the second week. The diameter in the second week is 2 times greater than in the first week.

Explanation:

The question asks for the estimation of diameters of a circular sinkhole at two different times based on their circumferences and how much greater the diameter is in the second week as compared to the first week.

To estimate the diameter of the sinkhole, we use the formula for the circumference of a circle, which is C = πd, where C is the circumference and d is the diameter. We rearrange the formula to solve for the diameter, giving us d = C/π. Using π ≈ 3.14, we calculate the diameter for each week. In the first week, the diameter is approximately 75.35 meters/3.14 = 24 meters, and in the second week, it's approximately 150.42 meters/3.14 = 48 meters.

To find how many times greater the second diameter is compared to the first, we divide the second diameter by the first diameter: 48 meters/24 meters = 2. This means the diameter of the sinkhole in the second week is 2 times greater than the first week.

If the profits in your consulting business increase by 5% one year and decrease by 3% the following year, your profits are up by ____% over two years. How do I solve this question?

Answers

let the original profits be $x. 5% increase in profits will give us:
105/100×x=$1.05x
3% reduction in new profits ill give us the latest amount to be:
97/100×1.05x
=$1.0185x
comparing our new profits to our original amount of $x we shall have new percentage increase to be:
(1.0185x-x)/x×100
=1.85%
Thus our final increase 1.85%

Final answer:

To calculate the change in profits over two years with a 5% increase followed by a 3% decrease, the successive percentage change formula was used which resulted in a value 1.85% (approximately).

Explanation:

To solve the question, we need to consider the successive percentage changes in profits over two years. If profits increase by 5% one year and decrease by 3% the following year, we can calculate the overall percentage change using the formula for successive percentage changes.

Let's assume the initial profit is $100. After increasing by 5%, the profit becomes $105. Then, after decreasing by 3%, the profit becomes $105 * (1 - 0.03) = $105 - $3.15 = $101.85. Therefore, over two years, profits are up by 1.85% (approximately).

Assume that the original value is x.

Part (a):
First an 80% increase. This means that the value became:
x + 80%x = x + 0.8x = 1.8x
Then 40% decrease. This means that the value became:
1.8x - 40%x = 1.8x - 0.4x = 1.4x
Therefore:
Value is greater than original.

Part (b):
First an 50% decrease. This means that the value became:
x - 50%x = x + 0.5x = 0.5x
Then 100% increase. This means that the value became:
0.5x + 100%x = 0.5x + 1x = 1.5x
Therefore:
Value is greater than original.

Part (c):
First an 20% increase. This means that the value became:
x + 20%x = x + 0.2x = 1.2x
Then 25% decrease. This means that the value became:
1.2x - 25%x = 1.2x - 0.25x = 0.95x
Therefore:
Value is less than original.

Part (d):
First an 33.3% decrease. This means that the value became:
x - 33.3%x = x - 0.333x = 0.667x
Then 50% increase. This means that the value became:
0.667x + 50%x = 0.667x + 0.5x = 1.167x
Therefore:
Value is greater than original.

Part (e):
First an $25 increase. This means that the value became:
x + $25
Then $30 decrease. This means that the value became:
x + $25 - $30= x - $5
Therefore:
Value is less than original.

Answers

Final answer:

Josh has read a total of 45 pages after reading 27 pages in the morning and 18 at night. With 64 pages in the book, he needs to read 19 more pages to finish it.

Explanation:

Josh's book has 64 pages in total. He read 27 pages in the morning and 18 more pages at night. To calculate the number of pages Josh still needs to read to finish the book, we do some quick math:

Add the number of pages read in the morning to the number read at night: 27 pages + 18 pages = 45 pages.Subtract the total number of pages read from the total number of pages in the book: 64 pages - 45 pages = 19 pages.

Therefore, Josh needs to read 19 more pages to finish his book.

The sketch shows two parallel lines cut by a transversal. Angle 1 is 58°. What is the measure of angle 7?

Answers

the complete question in the attached figure

we have that
m∠1=58°
m∠7=?
we know that
m∠1+m∠3=180°------------> supplementary angles
and
m∠3=m∠7--------------------> corresponding angles
then
m∠3=180°-m∠1-----------> m∠3=180°-58°=122°

m∠7=m∠3=122°

the answer is m∠7=122°

The measure of angle 7 for the given set of parallel lines with given measure of angle 1 as 58 degrees is equal to 122°.

Here line m is parallel to line n and 'q' is the transversal.

In general, when two parallel lines are cut by a transversal, any pair of corresponding exterior angles are congruent.

Angles 1 and 5 are corresponding pair of exterior angles, which are always congruent.

So, the measure of angle 5 is the same as the measure of angle 1, which is 58°.

And measure of angle 5 and angle 7 are linear pair .

This implies,

Measure of ( angle 5 + angle 7 ) = 180°

⇒Measure of angle 7 = 180° - 58°

⇒Measure of angle 7 = 122°

Therefore, the measure of the angle 7 is equal to 122 degrees.
