Answer:

5

Step-by-step explanation:

Area of bedroom = 13 1/3 square yards

Area of bed = 2 2/3 square yards

Unit Rate = Area of bedroom / Area of bed

Unit Rate = (40 / 3 ÷ 8/3)

Unit Rate = 5

Answer:

AC = 12.6

AB = 49.8

C = 73°

Step-by-step explanation:

(B/sin(14)) = (52/sin(93))

B = (52*sin(14))/sin(93)

B = 12.6

(C/sin(73)) = (52/sin(93))

C = (52*sin(73))/sin(93)

C = 49.8

Answer:

54/40 = 1.35 or 135%

Step-by-step explanation:

Your answer will be D.

So, you have the angles 12, 9, 6, and 3. You may see that the place that 6 is makes this a non perfect square. When you have this problem simply add the number on top of it with the number that makes this problem.

For instance...

[tex]\boxed{6+3=9}[/tex]

So, when finding area you must multiply the 2 lengths with each other.

So here our bottom length is also 12. Thus, we must multiply 9 and 12 together.

For instance...

[tex]\boxed{9*12=108}[/tex]

Answer:

1.5 inches

Step-by-step explanation:

1 inch = 16 miles

x = 24 miles

Cross multiply

16x = 24*1          

Divide by 16

x = 24/16

x = 3/2 = 1.5

Answer:

1. 50%

2. 3%

3. 20%

4. 200%

Step-by-step explanation:

Here, we want to find the worth of each coin as a percentage of $1

We simply divide the worth by $1 and multiply by 100%

$1 is same as 100 cents

Thus;

1. 50 cent

= 50/100 * 100% = 50%

2. 3 cents

= 3/100 * 100% = 3%

3. 20 cents

= 20/100 * 100% = 20%

4. $2

= 2/1 * 100% = 200%

Answer:

x=12, y=-3

Step-by-step explanation:

Plug (-4y) in for x in the top equation. The equation will now read 2(-4y) + 7y = 3. Distribute the 2 into the perenthecies getting: -8y+7y=3. -8+7 is -1 giving -y+3. Divide by -1 making y = -3. Plug -3 back into the top equation and solve for x: 2x + 7(-3)=3. 2x-21=3. 2x=24. x=12.

Answer:

1. The estimate of the proportion of mosquitoes in the area that carry the disease is approximately 0.1606 or 16.06%

2. To check for accuracy of the of the value of proportion of disease carrying mosquito in the area

Step-by-step explanation:

The given parameters are;

The number of mosquitoes in the sample = 137

The number of mosquitoes that carry the disease = 22

1. The estimate of the proportion of mosquitoes in the area that carry the disease = (Number of mosquitoes with the disease)/(The number of mosquitoes in the sample)

The estimate of the proportion of mosquitoes in the area that carry the disease = 22/137 ≈ 0.1606 or 16.06%

2. The reason the scientist run the simulations to find additional possible proportions of mosquitoes in the area that carry the disease is to check for variability and accuracy of the proportion of disease carrying mosquito in the area.

1. The proportion of mosquitoes in the region that carry the illness is estimated to be 16.06%.

2. To ensure that the proportion of disease-carrying mosquitos in the region is accurate.

A ratio is an ordered pair of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two ratios are specified to be equal.

Given data;

There were 137 mosquitos in the sample,[tex]\rm N_s[/tex]

The number of disease-carrying mosquitos is,[tex]\rm N_m[/tex]=22

The estimated proportion of disease-carrying mosquitos in the region is found as;

[tex]\rm D_m=\frac{N_m}{N_s} \\\\ \rm D_m=\frac{22}{137} \\\\ D_m=16.06 \ %[/tex]

2. The scientists used simulations to determine alternative probable proportions of disease-carrying mosquitos in the region in order to check for variability and accuracy in the proportion of disease-carrying mosquitos in the area.

Hence,the proportion of mosquitoes in the region that carry the illness is estimated to be 16.06%.

Answer:

D

Step-by-step explanation:

D

Answer: A is the answer

Step-by-step explanation:

Step-by-step explanation:

y = kx, where k is a real constant.

When x = 6, y = -12:

(-12) = (6)k

Therefore k = -2.

Hence y = -2x.

The direct variation of Y with X is Y = -2X.

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics. Simple algebraic equations with merely addition or multiplication to differential equations, exponential equations with exponential expressions, and integral equations are examples of different types of equations. They are employed to represent a number of physics laws.

As per the given data:

Y varies directly with X.

Y equals -12 when X equal 6.

Let's consider the equation Y = kX:

∴ -12 = k(6)

k = -2

Y = -2X

Hence, the direct variation of Y with X is Y = -2X.

Answer:

add them together and set them equal to 180

Step-by-step explanation:

They are both supplementary angles, so 15x+85+20x-10=180, so combine like terms=>35x+75=180

subtract 75 from both sides=>35x=105

divide both sides by 35 to get x alone=>x=3

plug that in for 20x-10

20(3)-10

=>60-10

=>50

Answer:

  Bob

Step-by-step explanation:

The "steepness," or slope, of the mountain is the ratio of height to horizontal distance to the base:

  Joe's mountain slope = 1200/1500 = 0.8

  Bob's mountain slope = 900/1000 = 0.9

Bob's mountain has a greater slope than Joe's. Bob climbed the steeper mountain.

Answer:

Transitive property of segment congruence

Step-by-step explanation:

The reflexive, symmetric, and transitive properties are the criterion for an equivalence relation. In terms of congruence,

In terms of general equivalence relations,

That's the transitive property.

The fact that congruence is transitive means exactly what you have written: if A is congruent to B and B is congruent to C, then you can "bridge" from A to C.

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

The value of x and y is 1 and -3.

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

Example:

2x + 4y = 6 is an equation.

2x = 4 is an equation.

4x - 6x + 6x = 6 is an equation.

We have,

x - y = 4 _____(1)

4x + y = 1 _____(2)

From (1) we get,

x = 4 + y ____(3)

Putting (3) in (2) we get,

4x + y = 1

4 (4 + y) + y = 1

16 + 4y + y = 1

16 + 5y = 1

Subtract 16 on both sides.

5y = 1 - 16

5y = -15

Divide both sides by 5.

y = -3

Now,

Putting y = -3 in (3) we get,

x = 4 + y

x = 4 - 3

x = 1

Thus,

The value of x and y is 1 and -3.

Answer:

A.

Step-by-step explanation:

The coordinates are currently on the top left, which means one of the coordinates are negative. If you look at the chart, you can see that the X-axis is negative, and X is first on a coordinate plane. (X,Y) So, if the negative coordinate is X, and X goes first, then there's no other choice than to choose A, which is the only answer choice that has a negative X-axis in their coordinate plane!
