what is the unit rate for the cost of a salad at the salad bar?

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

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:

The original number of cars in parking Lot A was 72 cars and the original number of cars in parking Lot B was 36 cars

Step-by-step explanation:

Let

x----> original number of cars in parking Lot A

y----> original number of cars in parking Lot B

we know that

x=2y ----> equation A

(x-10-13)=y+13 ----> equation B

substitute equation A in equation B and solve for y

(2y-10-13)=y+13

(2y-23)=y+13

2y-y=13+23

y=36 cars

Find the value of x

x=2y -----> x=2(36)=72 cars

therefore

The original number of cars in parking Lot A was 72 cars

The original number of cars in parking Lot B was 36 cars

Parking Lot B initially had 36 cars, and Parking Lot A had twice that amount, which is 72 cars. After 10 cars left Parking Lot A, and 13 cars were transferred from Parking Lot A to B, both lots ended up with the same number of cars.

The question asks us to solve a word problem involving the principle of algebraic equations to determine the number of cars in two parking lots. Let's refer to the number of cars in Parking Lot B as x. Therefore, Parking Lot A has 2x cars since it has twice as many cars as Parking Lot B.

According to the problem, after 10 cars leave Parking Lot A and 13 cars move from A to B, both lots end up with the same number of cars. We can set up the following equation to represent this scenario:

Initial condition: A has 2x cars, B has x cars.

10 cars leave A: A now has 2x - 10 cars.

13 cars move from A to B: A now has (2x - 10 - 13) cars, and B now has (x + 13) cars.

Both lots have the same number of cars: 2x - 10 - 13 = x + 13.

Solving the equation:

2x - 23 = x + 13

2x - x = 13 + 23

x = 36

Therefore, Parking Lot B initially had 36 cars, and Parking Lot A had 72 cars (2×36).

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.

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.

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.

Samuel should is looking to find the area of his basement in order to cover it with carpet.

An area is calculated by multiplying two dimensions (so answers A and D are not it).

Best solution is to divide the area into two large rectangles then ADD them together to get the total area.

The only scenario where he could have subtracted something based on his plan is if he would have multiplied the 10m by the 12m then subtracted the area that is not part of his basement (7mx8m).  He would have achieved the same result of course, but by going a different way.

The answer choice is D because sin7pi/6 which it’s exact form is -1/2 the only answer choice which the same exact form is D.

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

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

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.

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.
