On Friday, Tyler came up with the expression t= -0.5(1-2h) to represent the temperature change. His math teacher came up with the expression t= 4(2h+2) - 7h - 8.5 for the same day. Are these expressions equivalent or not?

Answer:

There are always two possible outcomes H (heads) and T (tails) but the possible combination outcomes are HH, TT, HT, and TH

Subtract x from both sides;

2x-x=x+9-x

Simplify;

x=9

The sales team must sell 8 more computers than they sold last month to receive the bonus.

Last month the sales team of Electronic Mania sold 27 computers.

If they sold 30% more computer than they sold last month, they would get a bonus.

First we find the 30 percent if 27

27 × 30/100

= 8.1

Let m be the total number of computers sold.

So, the total number of computers sold would be,

m = 27 + 8.1

m = 35.1

m ≈ 35

Therefore, they need to sell 35 computers in total.

Answer:

C is the correct answer

From the graph we can see that at the given interval [-6,0] the graph decreases from left to right.

Initially the y-values is a little over 3 and then it decreases to about 0.5 at the end of the interval.

Thus, the graph of the function over the interval [-6,0] is decreasing.

Answer:

B is the right answer

Step-by-step explanation:

Answer:

x = -7

Step-by-step explanation:

3x + 13 = -2x - 22

subtract 13 from both sides

3x = -2x - 35

Add 2x to both sides

5x = -35

Divide each side by 5

x = -7

Answer:

Volume of smallest container = 3141.6 cm³

Volume of middle sized container = 6283.2 cm³

Volume of largest container = 9424.8 cm³

Step-by-step explanation:

The formula to find the volume of a cylinder = πr²h

The height of each cylinder in a set of food-storage containers is 30 cm.

The radius of the largest container is 10 cm.

Step 1

We can find the volume of the largest cylinder

= r = 10cm

h = 30cm

Volume of largest cylinder = π × 10² × 30

= 9424.8 cm³

Step 2

We find the volume of the smallest container

We are told in the question:

The volume of the smallest container is one-third the volume of the largest container.

Hence

Volume of Smallest container = 1/3 (9424.8 cm³)

= 3141.6 cm³

Step 3

The volume of the middle-sized container is two-thirds the volume of the largest container.

Hence,

Volume of the middle sized container =

2/3 (9424.8 cm³)

= 6283.2 cm³

Therefore, the volume of each container is

Volume of smallest container = 3141.6 cm³

Volume of middle sized container = 6283.2 cm³

Volume of largest container = 9424.8 cm³

Answer:

3d^2

Step-by-step explanation:

First, find the GCF of 6 and 27, which is 3.

Factors of 6: 1, 2, 3, 6

Factors of 27: 1, 3, 9, 27

Then, find the greatest value of the variable d^3 and d^2, which is d^2. Since this is a variable, we just need to take out the highest degree accompanying the variable.

27(d^2)

6d(d^2)

Combine both of your findings to get 3d^2.

Step-by-step explanation:  Are you looking to work out and calculate how to multiply 3/8 by 3/4? In this really simple guide, we'll teach you exactly what 3/8 times 3/4 is and walk you through the step-by-process of how to multiply two fractions together.

Answer:

A. 45.7

Step-by-step explanation:

Side a = 8

Side b = 7.8

Side c = 11.17318

Angle ∠A = 45.725° = 45°43'31" = 0.79806 rad

Angle ∠B = 44.275° = 44°16'29" = 0.77274 rad

Angle ∠C = 90° = 1.5708 rad = π/2

=======================================================

Explanation:

Apply the tangent ratio and inverse tangent function (aka arctangent) to get the following

tan(angle) = opposite/adjacent

tan(x) = 8/7.8

x = arctan(8/7.8)

x = 45.7252242990592

x = 45.7

Subtract: 9/10 - 3/10

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 10) = 10. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 10 = 100. In the following intermediate step, cancel by a common factor of 2 gives 3/5. In other words - nine tenths minus three tenths is three fifths.

Solved equation is, x = 4/3 + 2y/3

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

here we have,

Write equation

6x - 4y = 8

Then,

Solve for x

Add 4y to both sides: 6x = 8 + 4y

Divide both sides by 6: x = 8/6 + 4y/6

Answer: y=1/4x-6

Step-by-step explanation:

The slope formula is y=mx+b

M- represents the rise over run.

B- represents where the line crosses over the y-axis.

So once you input the numbers you get 1/4 for m and -6 for b.

Answer:

we have :

(a+b+c)² = a² + b² + c² + 2(ab+bc+ca)

a+b+c= 9

and

ab+bc+ca = 26

Substituting the values in the above formula,

We get,

9² = a² + b² + c² + 2×26

81 = (a² +b² +c²) + 52

(a² +b²+c²) = 81-52

(a²+ b² + c²) = 29 is a required answer.
