A music store sold 10 to the third CDs and ten to the second CDs players if each CD costs $12 and each CD player costs $35, what was the stores total earnings

Answers

Answer 1

10^3 CDs with CD = $12 then total CDs earnings is (10^3)(12) = $12,000
10^2 CD players with CD plater = $35 then total CD player earnings is (10^2)(12) = $1,200
Total store earnings = ($12,000 + $1,200) = $13,200

For the first option, since when x is going down (to the left) the function is going up, it's not approaching 0. For the second option, since when x is going up (to the right) it's going up, it's not approaching negative infinity (negative infinity is all the way down). For the third one, since when x is going down the y values are climbing, we can assume that the function's values go to positive infinity. For the last one, since when x=0 y=0, when x=0 the function does not go to infinity

The sum of five consecutive numbers is -20. Which is the least of these five numbers?

Answers

Since the numbers are consecutive, they can be represented by:
x, x+1, x+2, x+3, x+4

Their sum is -20 = x+x+1+x+2+x+3+x+4. Result: -20=5x+10, or 5x=-30, or x = -6.

Then the numbers are -6, -5, -4, -3 and -2. These do add up to -20, as required.

The smallest of these is -6.

Consecutive numbers means 1,2,3 or 102,103,104 etc.

2,3,4,5,6 add to 20
So -2, -3, -4, -5, -6 add to -20

-6 is the least of the 5 consecutive numbers which sum to-20

Solve the equation. What is the value of x? x-6.8=356.3

Answers

the answer is 363.1 i used a calculater to find the answer. so 356.3+ 6.8 = 363.1 so x=363.1

To solve the equation x - 6.8 = 356.3, add 6.8 to both sides to isolate x, resulting in x = 363.1.

To solve the equation x - 6.8 = 356.3, we need to isolate the variable x. To do this, we can add 6.8 to both sides of the equation, effectively moving the 6.8 from the left side to the right.

Step-by-step:

Add 6.8 to both sides: x - 6.8 + 6.8 = 356.3 + 6.8Simplify both sides: x = 363.1

The value of x is 363.1.

For every 240 days of milking, cow's milk production decreases by 2.

Which shows the average change in cow's production?

A. -120 gallons per day
B. - (1/120) gallons per day
C. 1/20 gallons per day.
D. 120 gallons per day.

Answers

It's B. 1/120 gallons per day

The solution is Option B.

The slope / average change in cow's production is m = - 1/120 gallons per day

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of the equation A is

For every 240 days of milking, cow's milk production decreases by 2

So , the value of y = 2 gallons

The value of x = 240 days

Now , the slope of the equation is given as

Slope m = y/x

And , The slope of a line is a measure of its steepness, slope is calculated as "rise over run" or change in y divided by change in x

Substituting the values in the equation , we get

Slope m = 2/240

Slope m = 1/120

Since the cow's milk production decreases by 2 , the slope will be negative

So , slope m = -1/120 gallons / day

Hence , the average change in cow's production is -1/120 gallons / day

The answer would be 1.324

One and three hundred twenty four thousandths expressed as a decimal numeral is [tex]1.324[/tex].

To express "one and three hundred twenty four thousandths" as a decimal numeral, follow these steps:

Understand the components:

• "One" represents the whole number part.

• "Three hundred twenty four thousandths" represents the fractional part.

Express the whole number part as a decimal:

• The whole number "one" is simply [tex]1[/tex].

Convert the fractional part to a decimal:

• "Three hundred twenty four thousandths" means 324 out of 1000, which can be written as the fraction [tex]\frac{324}{1000}[/tex].

• To convert [tex]\frac{324}{1000}[/tex] to a decimal, divide 324 by 1000. This gives us [tex]0.324[/tex].

PLEASE HELP ...... Geometry Homework, I'll give brainliest

Answers

There are a few facts we'll need to hold onto for this problem:

- Supplementary angles (two angles that form a straight angle when added) add to 180°
- The interior angles of a triangle add to 180°
- Sides opposite congruent angles in a triangle are also congruent
- Alternate interior angles are congruent when formed by a transversal through two parallel lines

With that in mind, let's get to the problem. First, what data have we been given?

Let's drop another point on the ground to the left of point T called S, so we can get all of this data together. We know that:

[tex]AB = 2.4\ mi\\\overrightarrow{ST}||\overrightarrow{AC}\\\angle{ATS}=40\textdegree\\\angle{BTS}=80\textdegree[/tex]

We don't know the measure of ∠ATB, but we do know that it shares the larger angle ∠BTS (which is 80°) with ∠ATS (which is 40°). Since ∠ATB + ∠ATS = ∠BTS, we can clearly see that ∠ATB must also be 40°, so now we have the new data that ∠ATB = 40° to work with.

Next, notice that ∠BTS and ∠CBT are alternate interior angles, and the lines they rest on, [tex]\overrightarrow{ST}[/tex] and [tex]\overrightarrow{AC}[/tex], are parallel. This implies that ∠BTS and ∠CBT are congruent, which makes ∠CBT = 80°.

∠CBT and its neighboring angle ∠ABT, when combined, form a straight angle, making them supplementary to one another. This means that ∠CBT + ∠ABT = 180°, or 80° + ∠ABT = 180°. Subtracting 80° from both sides, we see that ∠ABT = 100°.

We're almost done; we now bring our attention now to the triangle formed by the points ABT. What do we know about this triangle? We're given that one of its sides, AB, is equal to 2.4 mi; most recently, we determined that one of its angles, ∠ABT, was equal to 100°; and even earlier, we found that the second one of its angles, ∠ATB, was equal to 40°. We have two angles and a side, which, as I'm about to demonstrate, is more than enough for our purposes. If we've found the measures of two angles of triangle ABT, we can use the fact that a triangle's interior angles add to 180° to find the third angle, ∠BAT. We have:

∠ABT + ∠BTA + ∠BAT = 180°

Substituting ∠ABT and ∠BTA for the values we found for them:

100° + 40° + ∠BAT = 180°
140° + ∠BAT = 180°
∠BAT = 40°

We now know that ∠BAT and ∠BTA are congruent, which means that the triangle BTA is isoceles. This means that the sides opposite those angles will also be congruent. The side opposite ∠BTA is the line segment AB, which we know to be 2.4 mi, which means the side opposite ∠BAT, BT - the side we've been looking for - must also be 2.4 mi.

74=53-7x I have to solve for x and havent quite grasped the concept of algebra

Answers

If 74 = 53-7 • x you have to figure out the rest of the problem by working backward.
53 - 7 = 46
So you have to divide 74 and 46 to get x.
74/46 = 1.6086
You then multiply 1.6086 and 46 which is 73.995 which rounds to 74.
53-7 = 46; 74/46 = 1.6086; 1.6086 • 46 = 74

If seven pencils cost $.84 find the cost of 10 pencils

Answers

Salutations!

If seven pencils cost $.84 find the cost of 10 pencils?

Lets solve this!

To solve this question, you need to first divide .84 ÷ 7 which gives you the answer 0.12. Then multiply 0.12 with 10 which gives you the cost of 10 pencils. 0.12 is the cost of only one pencil.

Lets forms this into statements ---

Cost of 7 pencils = $ .84

Cost of 1 pencil = $ 0.12

Cost of 10 pencil equals = .84 ÷ 7 = 0.12

= 0.12 × 10 = 1.2

Cost of 10 pencils is $1.2

Hope I helped (:

Have a great day!

Final answer:

To calculate the cost of 10 pencils when seven pencils cost $0.84, you find the price per pencil by dividing $0.84 by 7, which equals $0.12 per pencil. Then, multiply $0.12 by 10 to get the total cost of 10 pencils, which is $1.20.

Explanation:

To answer the question, we first need to find the cost of one pencil. Since seven pencils cost $0.84, we can divide that amount by seven to get the cost of one pencil.

Here is the calculation:

Cost of seven pencils = $0.84

Cost of one pencil = $0.84 ÷ 7

Cost of one pencil = $0.12

Now that we know the cost of one pencil, we can find the cost of 10 pencils by multiplying this amount by 10.

Here is the calculation:

Cost of 10 pencils = $0.12 × 10

Cost of 10 pencils = $1.20Therefore, the cost of 10 pencils is $1.20.
