What is the product?

Let's try all of the possible answer choices.

Any result that is even, we cross off the list. Otherwise we have our answer.

If c = -8, then c-8 = -8-8 = -16 which is even. Cross this off the list

If c = 0, then c-8 = 0-8 = -8, which is even. Cross this off the list.

If c = -5, then c-8 = -5-8 = -13, which is odd. We have our answer

If c = 10, then c-8 = 10-8 = 2, which is even. Cross this off the list

Answer:

log 5 5

= 1.

Step-by-step explanation:

Use the logarithm law  loga b - loga c = loga b/c:

log5 125 – log5 25

= log5 125 / 25

= log5 5.

= 1.

The expression log5 125 - log5 25 simplifies to 1.

To combine the logarithms log5 125 and log5 25 as one logarithm and simplify, we can use the properties of logarithms. Specifically, we'll use the property that states logb(x) - logb(y) = logb(x/y). Applying this property, we have:

log5 125 - log5 25 = log5 (125/25)

We simplify the fraction 125/25 to get 5. So, we have:

log5 (125/25) = log5 5

The logarithm of a number to the base of itself is always 1, so:

log5 5 = 1

Therefore, the expression log5 125 - log5 25 simplifies to 1.

Answer:

She needs  15 Strawberries and 6 Oranges to make 12  servings of fruit salad

Step-by-step explanation:

Strawberries : (12 x 10)/ 8 = 15

Oranges: (12 x 4)/8 = 6

12 servings = 8 and half of 8 (8+4=12)

15 strawberries =10 and half of 10 (10+5=15)

Step-by-step explanation:

no but you are very close

you forgot to put the x next to the -4

because if you left it like that than it would be a horizontal line going through the y-axis at -4

the x is very important since it is the input value while y is the output

so y depends on the x

Answer:

Answer:

The trip is 50miles far

Step-by-step explanation:

If they have travel 15miles which is equal to 30% of the trip.

To find how far the trip is.

Let x represent the trip in miles

Therefore:

30% of x is 15miles

30/100 * x = 15miles

x = 15 miles ÷ 30/100

x = 15 miles * 100/30

x = 1500miles/30

x = 50miles

Answer:

The surface area of a conical grain storage tank that has a height of 41 meters and a diameter of 16 meters is[tex]1250.9 m^2[/tex]

Explanation:

Height of the conical grain storage tanks =41 m

Diameter of the conical grain storage tank=16 m

Hence radius = diameter/2=8 m

Suppose h is height and r is radius

Formula used:  

Surface area of a cone= A

A= [tex]\pi rl +\pi r^2[/tex]

= πr(l+r)

Where[tex]l =(r^2+h^2)^1^/^2[/tex]

=[tex]\pi r(r+(h^2+r^2)^1^/^2)[/tex]

Putting the values

=[tex]3.14 \times 8\left(8+\left(41^{2}+8^{2}\right)^{1 / 2}\right)[/tex]

=1250.9368

=[tex]1250.9 m^2[/tex]

[tex]1250.9 m^2[/tex] is the surface area of a conical grain storage tank

Answer:

y = 2

Step-by-step explanation:

When line is horizontal, all points on this line have the same value of y.

In this case , all points have to have y = 2.

y = 2, is an equation of horizontal line.

The equation of  line y = 2 represents the horizontal line passing through (-1,2).

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have given a point (-1, 2) on a coordinate plane.

The distance from origin (0, 0) and (0, 2) is 2

And line y = 2 represents the horizontal line that passes through (-1, 2)

Thus, the equation of  line y = 2 represents the horizontal line passing through (-1,2).

For this case we must solve the following system of equations:

[tex]3x-3y = -3\\2x-y = -5[/tex]

To solve we follow the steps below:

We multiply the second equation by -3:

[tex]-6x + 3y = 15[/tex]

Thus, we have the equivalent system:

[tex]3x-3y = -3\\-6x + 3y = 15[/tex]

We add the equations:

[tex]3x-6x-3y + 3y = -3 + 15\\-3x = -3 + 15\\-3x = 12\\x = \frac {12} {- 3}\\x = -4[/tex]

We look for the value of the variable "y":

[tex]2 (-4) -y = -5\\-8-y = -5\\-y = -5 + 8\\-y = 3\\y = -3[/tex]

Thus, the solution of the system is given by:

To find the probability of at least one defective microscope in a batch of 50, we first calculate the probability of all 50 being non-defective and then subtract this from 1. The resulting probability of having at least one defective microscope in the batch is approximately 7.96%.

The question is about finding the probability that one of the first 50 microscopes manufactured by LabTech is defective. Given the probability of a microscope being defective is 0.17%, we can calculate this by multiplying the probability of a single microscope being defective by the total number of microscopes.

Firstly, convert the 0.17% to a decimal by dividing by 100, which gives us 0.0017. This is the probability of a single microscope being defective. Then, to find out the probability of at least one out of 50 being defective, we would consider the opposite - the probability of all 50 microscopes being non-defective. If one microscope has a 0.0017 chance of being defective, it has a 1-0.0017 = 0.9983 chance of being non-defective.

The chance of all 50 microscopes being non-defective is [tex](0.9983)^{50} = 0.9204.[/tex] Therefore, the probability of at least one out of 50 being defective is 1 - 0.9204 = 0.0796 or 7.96%.

Final answer:

The probability that at least one of the first 50 microscopes manufactured is defective is calculated using the complement rule, by subtracting the probability of none being defective from 1, the answer is 0.082

Explanation:

To find the probability that at least one of the first 50 microscopes LabTech manufactures is defective, we use the complement rule. The probability that a microscope is not defective is 1 - 0.0017 (since 0.17% as a decimal is 0.0017). To find the probability that none of the microscopes out of the 50 produced are defective, we raise this to the power of 50:

P(no defective microscopes) = [tex](1 - 0.0017)^{50[/tex]

Then, to find the probability that at least one microscope is defective, we subtract this from 1:

P(at least one defective microscope) = [tex]1 - (1 - 0.0017)^{50[/tex]

P(at least one defective microscope)= 1-0.918= 0.082

Explanation:

1/5 of the tiles are indian red

3/10 of the tiles are Tuscan blue

1/6 of the tiles are eucalyptus

x of the tiles are sand, where x is some fraction

The four fractions listed above add to 1. The "1" refers to a whole back splash, in which you can think of "1" as "100%"

-----------

We have the fractions 1/5, 3/10 and 1/6

To combine these fractions, we need a common denominator. In this case, the lowest common denominator (LCD) is 30 as this is the LCM of the denominators 5, 10, and 6.

Let's get each fraction to have a denominator of 30

1/5 = (6/6)*(1/5) = 6/30

3/10 = (3/3)*(3/10) = 9/30

1/6 = (5/5)*(1/6) = 5/30

-----------

So effectively we have these fractions: 6/30, 9/30, and 5/30

They add to the unknown fraction x to get 1

Let's solve for x.

-----------

(1/5) + (3/10) + (1/6) + x = 1

(6/30) + (9/30) + (5/30) + x = 1

(6/30 + 9/30 + 5/30) + x = 1

(6 + 9 + 5)/30 + x = 1

20/30 + x = 1

2/3 + x = 1

x + 2/3 = 1

x+2/3-2/3=1-2/3 ... subtract 2/3 from both sides

x = 1 - 2/3

x = 3/3 - 2/3

x = (3 - 2)/3

x = 1/3

1/3 of the tiles are the color of sand

Final answer:

One third of the tiles will be the color of sand. This is found by adding the fractions of the other colors, simplifying, and subtracting from one whole set of tiles.

Explanation:

To find the fraction of the tiles that will be the color of sand, we first need to calculate the total fraction of tiles that have already been assigned colors: Indian red, Tuscan blue, and eucalyptus. Then we subtract this total from 1, which represents the whole set of tiles, to find the remaining fraction for the sand-colored tiles.

Adding these fractions:

Now, we convert 10/15 to a simplified fraction:

To find the fraction for sand-colored tiles, subtract the total colored fraction from 1:

Therefore, one third of the tiles will be the color of sand.

Answer:

24.5% are green

Step-by-step explanation:

a) The quantities vary directly

b) The constant of variation is 2.5

Step-by-step explanation:

Lets us revise the direct and inverse variation

∵ 16 factory workers made 40 pieces in a certain amount of time

- If the number of worker increased, then the number of pieces

   increased in the same certain time, if the number of worker

   decreased, then the number of pieces also decrease in the

   same certain time

∴ The the number of workers and the number of pieces produce

   vary directly

∴ Number of pieces produced = k × number of worker

a) The quantities vary directly

∵ The number of worker = 16

∵ The number of pieces produced = 40

- Substitute these values in the equation of variation above

∴ 40 = k × 16

- Divide both sides by 16

∴ k = 2.5

b) The constant of variation is 2.5
