Answer:

hey this is the answer

Step-by-step explanation:

x= -12,y= -3

Step-by-step explanation:

First, let's get out common denominators.

8/12 and 3/12.

We have 5/12.

That's your answer.

Answer:

pi*486mm ^3

Step-by-step explanation:

The equation of a hemisphere is half of that of a sphere, therefore it is 2/3pi*radius^3

We must calculate radius, which is just diameter/2 so 18/2 or 9

We can remove pi, as you want this measured in pi cubic millimeters.

this leaves us with (2/3)*9^3 which is 486cm

Henceforth, the final answer is pi*486 cubic millimeters.

Answer:

Answer is C on Ed

Step-by-step explanation:

Answer:

C.Ralph would save more, since he has $30,000 more in principal

Step-by-step explanation:

The amount of interest each will pay (or save) on his loan is proportional to the amount of principal. Since Ralph's principal of $98000 is more than David's principal of $68000, Ralph will save more by paying off the loan early.

Answer:

Part 1) and Part 2) in the procedure

Step-by-step explanation:

step 1

Find the measures of angles

we know that

The sum of the angles A, B and C must be equal to 360 degrees

Using a protractor

The measures of angles are

∠A=140°

∠B=100°

∠C=120°

step 2

Ordered the measures of the angles from least to greatest

1) ∠B=100°

2) ∠C=120°

3) ∠A=140°

Answer:

Step-by-step explanation:

The perimeter is the arc length plus the two radius lines.

Arc length is:

s = (θ/360) 2πr

So the perimeter is:

P = (θ/360) 2πr + 2r

Given that θ=135 and r = 11:

P = (135/360) 2π(11) + 2(11)

P = 8.25π + 22

P ≈ 47.9

So the perimeter is greater than 47.5 cm.

A nine cubic millimeters

The volume of a cube with each dimension being 3 mm is obtained by multiplying the length, width, and height which results in 27 cubic millimeters. So the correct answer is C) 27 cubic millimeters.

To solve for the volume of a cube, the formula Volume = Length x Width x Height is used. In the case given, all three dimensions (length, width, and height) are 3 mm. This results in Volume = 3 mm x 3 mm x 3 mm which simplifies to 27 cubic millimeters.

Hence, the correct option is C) 27 cubic millimeters.

Answer:

The last option choice [(1,3), (2,6), (3,9), (4,12)

Step-by-step explanation:

The key idea to understand in a function/relation is that each input can only have one output. Inputs are your x-variables and outputs are your y-variables.

In the first relation, you see the two points (3,4) and (3,5). 3 is your input [since its x] , however, it gives you two outputs [y's], 4 and 5. So you can cross out the first option.

In the second relation, look at the points (3,4) and (3,3). Again, both have the same input 3, but different outputs, 4 and 3. So you can cross out the second option.

In the third relation, look at all of the points. They all share a common input, 1, but different outputs, 2, 3, 4, and 5. So you can cross out the third option too.

Lastly, look at the last relation. They all have different inputs but the key thing to look at here is that each input only has one corresponding output. Thus, this is the right answer.

I hope this helps!

Answer:

x > -5

Step-by-step explanation:

-5(x+7)<-10

Divide each side by -5.  Remember to flip the inequality

-5/-5(x+7)>-10/-5

x+7 > 2

Subtract 7 from each side

x+7-7>2-7

x > -5

Answer:

x = -10

Step-by-step explanation:

-3/4 (x+2) = 6

Multiply each side of the equation by -4/3 to clear the fraction

-4/3 *-3/4 (x+2) = 6*-4/3

(x+2) = 2*-4

x+2 = -8

Subtract 2 from each side

x+2-2 = -8-2

x=-10

So, from the division, we have to equal right triangles, which on leg is 6, and its angle is 80°, being the height the other leg.

Now, to find the height, we have to use trigonometric reasons, specifically, the tangent reasons because involves a relation with both legs

Step-by-step explanation:

Probability is the ratio of the favorable event to the total number of events. Then P(A|B) is 0.40.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

This Venn diagram shows sports played by 10 students.

Let event A = The students play basketball.

Let event B = The student plays soccer.

Then the probability of the will be

[tex]\rm P(A|B) = \dfrac{P(A \cap B)}{P(B)}\\\\\\P(A|B) = \dfrac{\dfrac{2}{10}}{\dfrac{5}{10}}\\\\\\P(A|B) = \dfrac{2}{5} = 0.40[/tex]

Thus, P(A|B) is 0.40.

Step-by-step explanation:

Keep track of every 1, 2, 3, or 4 rolled in 30 rolls and repeat this process 100 times to represent the days the temperature is above 80°F in June.

The BEST way to perform the simulation in this scenario would be to keep track of every 1, 2, 3, or 4 rolled in 30 rolls, as these represent the number of days the temperature is above 80°F in June. Repeat this process 100 times.

By simulating the number of days the temperature is above 80°F in June for 30 rolls and repeating it 100 times, you will obtain a larger sample size and a more accurate estimate of the probability. This approach allows for more data points and reduces the impact of random variations that can occur in smaller sample sizes.

Therefore, option 3 is the best way to perform the simulation: Keep track of every 1, 2, 3, or 4 rolled in 30 rolls and repeat this process 100 times to represent the days the temperature is above 80°F in June.

Answer:

1 and 3

Step-by-step explanation:

To simplify 4(6r+3) + 2(r + 2), distribute the coefficients, combine like terms, resulting in the simplified expression 26r + 16.

To simplify the expression 4(6r+3) + 2(r + 2), we need to distribute the multiplication over the addition inside the parentheses and then combine like terms.

Distribute the 4 into the first set of parentheses: 4 × 6r = 24r and 4 × 3 = 12.

Do the same with the 2 into the second set of parentheses: 2 × r = 2r and 2 × 2 = 4.

Now, combine the individual terms: The expression becomes 24r + 12 + 2r + 4.

Combine like terms (24r and 2r) and constants (12 and 4): 24r + 2r = 26r and 12 + 4 = 16.

The simplified expression is therefore 26r + 16.

Answer:

2in

Step-by-step explanation:

Let's call the original side "x". so x² (area of a square) is = x² (as we can't simplify it). Then we got a 4 added to each side. So now we redefine each side as "x+4". So now we can make an equation of the area of the square. x² + 4² = 36. Now you realize that 36 is 6² so you write it. x² + 4² = 6² . Since everything is now a square just square root everything (√) So Now x + 4 = 6. Now you have a 1st degree equation now solve simple math. x = 6 - 4 = 2. The side of original square is 2in

Answer:

a = 70°

Step-by-step explanation:

a and 110 form a straight angle, thus

a + 110 = 180 ( subtract 110 from both sides )

a = 70°

Answer:

a =70

Step-by-step explanation:

Angle a and 110 are supplementary, which means they add to 180 degrees

a+ 110 = 180

Subtract 110 from each side

a+110-100=180-110

a = 70
