110ft²

Area of figure=(10×8)+(1/2×6×8)

=80+24

=112 ft²

=110 ft² (to nearest tenth)

Answer:

Step-by-step explanation:

To overestimate the area would mean that you completely enclose the circle in squares; an 8 x 8 square to b exact. The area of a square with sides measuring 8 is 64. The overestimation is 64.

To underestimate the area would mean that you only count the squares that are completely inside the circle. That would be a 6 x 6 square (even though the 6th squares are a tiny bit outside the circle). A square with sides of 6 has an area of 36. The underestimation is 36.

Answer:

Step-by-step explanation:

Range is y thing, where as domain is an x thing. The way you state a range (or a domain, for that matter) is to start from the low point on the graph and go up to the high point. Our graph doesn't have a starting point; therefore, the "low" end of the graph comes up from -∞. The high point on the graph maxes out at 3. Therefore, the proper way to state the range (depending upon whether you use set-builder or not) is

R = (-∞, 3] or another way to state this is

R = {y | y ≤ 3} which reads "y such that y is less than or equal to 3".

Answer:

[tex]2.51\:\mathrm{rad/s}[/tex]

Step-by-step explanation:

Angular speed is given by [tex]\omega=\frac{\Delta \theta}{\Delta t}[/tex], where [tex]\Delta \theta[/tex] is angle change in radians and [tex]\Delta t[/tex] is elapsed time.

Since the hammer makes one full rotation in 2.5 seconds, it is travelling 360 degrees or [tex]2\pi[/tex] radians every 2.5 seconds.

Thus, we have:

[tex]\omega=\frac{2\pi}{2.5}\approx \boxed{2.51\:\mathrm{rad/s}}[/tex]

Answer: [tex]3^{\circ}C[/tex]

Step-by-step explanation:

Given

The temperature on Monday was [tex]-5^{\circ}C[/tex]

By Tuesday, it becomes [tex]-2^{\circ}C[/tex]

Change in temperature is the difference between the two temperatures.

[tex]\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C[/tex]

Therefore, the change in temperature is [tex]3^{\circ}C[/tex].

Answer:

The wood from the birch tree has a greater density than the wood that came from the cypress tree.

Step-by-step explanation:

Density formula: mass/volume

2 times 4 times 3=24 meters for the volume

Birch tree: 16/24 is the density

3 times 5 times 2=30 meters for the volume

Cypress tree: 15.3/30 is the density

If we convert the densities of each piece of wood to decimal it will be easier to determine which has a greater density.

So birch tree: 0.6 repeating is the density

Cypress tree: 0.51 is the density

Therefore the wood that came from the birch tree has a greater density than the wood that came from the cypress tree.

Answer:The ratio of the number of red balls to yellow balls in a bag is 4:5 there are 270 balls in the bag

Step-by-step explanation:

As per linear equation, there are 120 red balls and 150 yellow balls in the bag.

A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.

Given, the ratio of the number of red balls to yellow balls in a bag is 4:5. There are 270 balls in the bag.

Let, there are 4x red balls in the bag.

Therefore, there are 5x yellow balls in the bag.

Now, (4x + 5x) = 270

⇒ 9x = 270

⇒ x = 270/9

⇒ x = 30

The number of red balls = 4x = 4 × 30 = 120.

The number of yellow balls = 5x = 5 × 30 = 150.

To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value –

The mean absolute deviation of the number of siblings in the data given is: 1.33.

Find the mean, the calculate the average of the difference of each data point and the mean.

Given the data:

0, 2, 4, 1, 3, 5, 0, 1, 1, 0, 3, 2, 4, 0, 1, 3, 2, 1, 6, 2, 1, 0, 1, 3

Mean = 1.9167

Mean absolute deviation = [(0 - 1.9167) + ( 2 - 1.9167) + ( 4 - 1.9167) + ( 1 - 1.9167) + ( 3 - 1.9167) + ( 5 - 1.9167) + ( 0 - 1.9167) + ( 1 - 1.9167) + ( 1 - 1.9167) + ( 0 - 1.9167) + ( 3 - 1.9167) + ( 2 - 1.9167) + ( 4 - 1.9167) + ( 0 - 1.9167) + ( 1 - 1.9167) + ( 3 - 1.9167) + ( 2 - 1.9167) + ( 1 - 1.9167) + ( 6 - 1.9167) + ( 2 - 1.9167) + ( 1 - 1.9167) + ( 0 - 1.9167) + ( 1 - 1.9167) + ( 3 - 1.9167)]/24

Answer:

x=8

Angles = 120

Step-by-step explanation:

The angles are corresponding angles and corresponding angles are equal when the lines are parallel

14x+8 = 16x -8

Subtract 14x from each side

14x+8-14x = 16x-14x -8

8 = 2x-8

Add 8 to each side

8+8 = 2x-8+8

16 =2x

Divide by 2

16/2 = 2x/2

8 =x

The angles are equal

14x+8 = 14(8) +8 = 120

Given:

2 angles,

14x + 8

16x - 8

To find:

The value of x

Steps:

Since the 2 lines are parallel and there is an intersecting line, then the angles are corresponding to each other. So,

14x + 8 = 16x - 8

Bringing the like terms together, we get

8 + 8 = 16x - 14x

    16 = 2x

    2x = 16

      x = 16/2

      x = 8

So,

14x + 8 = 14(8) + 8 = 112 + 8 = 120°

16x - 8 = 16(8) - 8 = 128 - 8 = 120°

Therefore, the value of x is 8 and the measure of the angles is 120° for both as both angles are corresponding angles

Answer:

it is about 3.78 if you round to the nearest hundredth

Answer:

First, we know that a single liter of milk weighs around 1.032 kg.

Then 7 kilograms of milk is equivalent to (almost) 7 liters of milk.

Now, this is reasonable?

Well, for a typical person, the consumption is between 0.5L and 0.75L

So 7kg of milk may less of what a typical family consumes in a week, but is not an outlier (for example, 30kg of milk or 1kg of milk per week are outliers, which are "nonreasonable") so 7 kg is a reasonable amount of milk.

Now, if the question only refers to the units he used (kg instead of liters) this does not matter, as we know, mass and volume are two different, but equivalent, ways of describing a known matter, as these are related by the density:

Density = mass/volume.

So, for a known material, if you know the mass that you have, you also know the volume.

Then using kg is reasonable in this situation.

Answer:

19 Five is not tangent to the circle.

20 Eight is tangent to the circle.

Step-by-step explanation:

In order for one of the legs to be a tangent to a circle, the length must be part of a right angle triple.

I don't think the diagram on the left is, but I'll check it.

5^2 + 12^2 =

25 + 144 =

169

square root of 169 is 13

The length of the hypotenuse should be 13 not 14. Fourteen does not make Pythagorean triple. 13 would. So the line 5  units long does not make a tangent to the given circle.

The diagram on the right is a different story. 6 8 and 10 do make a Pythagorean triple, even though the two diagrams are not the same.

The radius and the distance to the external point  form a right angle.

The Pythagorean triple is

6^2 + 8^2 = 10^2

36 + 64 = 100  

100 = 100

Answer:

P(A or B) = 25%

Step-by-step explanation:

P(B) = 15%

P(A or B) = P(A) + P(B) - P(AB)

Answer:

the probability is 50% or 1/2 (equally likely and equally unlikely)

That is because it does not state the amount of socks inside the draw; meaning the answer has to be theoretical.

If the probability is the same, than it has to equal to 100

so we can conclude that 1/2 of the drawer is blue socks and 1/2 is white socks.
