Answer:

68°

Step-by-step explanation:

To find the angles represented by the percentages , you should have in mind that the total sum of all angles in the pie-chart equals 360°

The percentages given are;

The total percentages for the items

[tex]=34+8+11+12+15+20=100[/tex]

To get the angles represented by each percentage

Angle x=item/100 ×360°

Where x is the angle of an item in the circle graph

Calculating angles for carrot and potatoes

[tex]C=\frac{11}{100} *360=39.6\\\\\\P=\frac{8}{100} *360=28.8\\\\\\P+C=39.6+28.8=68.4[/tex]

The combined angle will be 68.4°

For this case we must simplify the following expression:

[tex]\frac {\frac {4t ^ 2-16} {8}} {\frac {t-2} {6}} =[/tex]

Applying double C we have:

[tex]\frac {6 (4t ^ 2-16)} {8 (t-2)} =[/tex]

Simplifying:

[tex]\frac {3 (4t ^ 2-16)} {4 (t-2)} =[/tex]

We take common factor 4 from the parentheses of the numerator:

[tex]\frac {3 * 4 (t ^ 2-4)} {4 (t-2)} =[/tex]

We simplify:

[tex]\frac {3 (t ^ 2-4)} {(t-2)} =[/tex]

We factor the numerator:

[tex]t ^ 2-4 = (t + 2) (t-2)[/tex]

We rewrite the expression:

[tex]\frac {3 (t + 2) (t-2)} {(t-2)} =[/tex]

We simplify:

[tex]3 (t + 2) =\\3t + 6[/tex]

Answer:

[tex]3t + 6[/tex]

Answer:

[tex]y=-0.10x+60[/tex]

Step-by-step explanation:

Let

y -----> gallons of water remaining in the barrel

x-----> number of minutes elapsed

we know that

Water leaks out of the barrel at a rate of 1 gallon every 10 minutes

so

[tex]1/10=0.10\frac{gal}{min}[/tex]

The linear equation that represent this situation is  

[tex]y=-0.10x+60[/tex]

Answer: D is correct dotted and shaded below

Step-by-step explanation:

It’s a dotted line because the symbol is < or >

Everything below the line will be shaded because it’s y<, if it were y> then everything would be shaded above

Answer:

A shaded region below a dashed boundary line

Step-by-step explanation:

Conveniently it has been established, that in inequalities graph dashed lines indicate that all the points ∈ line expressed by y< -1/2x+5 part of the inequality are not included. So we represent by shaded regions below dashed lines.

If this inequality was then expressed by y<= -1/2x +5 then a solid line would then represent.

Answer:

180°

Step-by-step explanation:

(8y+17)°=(6x-7)°

(3x-29)°+(8y+17)°=180°

so,

(3x-29)°+(6x-7)°=180°

To solve the expression (6x-7)+(3x-29), we combine like terms. The 'x' terms (6x + 3x) sum up to 9x and the constants (-7 and -29) sum up to -36. Therefore, the simplified expression is 9x - 36.

The student wants to solve the expression (6x-7)+(3x-29). To do this,  you should combine like terms, which means you should add together the terms that have the same variable.

Step 1: Add the 'x' terms together. This would give us 6x + 3x which equals 9x.

Step 2: Then add the constants together, in this case -7 and -29, you get -36.

So, the simplified result of the expression (6x-7)+(3x-29) is 9x - 36.

Step-by-step explanation:

Area of the shape =

136 =  6 * 14 + (h/2)(12 + 14)      where the last part is the area of the trapezoid.

Answer:

x = 98

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

∠x is an exterior angle and

∠GFH and ∠FHG are the 2 opposite interior angles, hence

x = 53 + 45 = 98

The value of x is 98 degree.

If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

∠GFH and ∠FHG are the 2 opposite interior angles to exterior angle 'x',

x = 53 + 45

x = 98

Hence, the value of x is 98 degree.

Answer:

Possible values of dimensions are (24,16,2) or (24,8,4)

Step-by-step explanation:

We are given the volume of the Cuboid and length . We are required to find the possible values of width and height from this information.

Let us say that the width is x and height is y

Length = 24

Volume of a cuboid = length * width * height

Volume = 768

768=24*x*y

[tex]xy=\frac{768}{24}\\xy=32\\[/tex]

xy=32

Now the possible factors of 32

32=1*32 ( Which shall not be taken into consideration as length is already given as 24 and width or height can  not be more length)

32=2*16

32=4*8

Hence the possible values width are 8, 16 and that of height 4 and 2

Hence the possible values of dimensions are (24,16,2) or (24,8,4)

The correct answer is option C.  -6x³ - 6x

Step-by-step explanation:

It is given an expression,

(4x³ + 3x² - 6x) - ( 10x³ + 3x²)

To find the simplified form

(4x³ + 3x² - 6x) - ( 10x³ + 3x²) = 4x³ + 3x² - 6x - 10x³ - 3x²

 = 4x³ - 10x³ + 3x² - 3x² - 6x

 = -6x³ + 0 - 6x

 = -6x³ - 6x

C

Step-by-step explanation:

A major arc is an arc that is greater than 180 degrees.

A minor arc is an arc less than 180 degrees.

An acute angle is an angle less than 90 degrees.

A central angle is the angle created in the center of a circle with 2 sides being the radius.

Thus, we can see in the figure that we are talking about the angle so we can eliminate major arc and minor arc.

Now, we clearly see that the angle is greater than 90 degree so it cannot be acute angle.

The correct answer is central angle as it goes with the definition.

Final answer:

AOR or Adjusted Odds Ratio is used in medicine as a measure of association between exposures and outcomes, and it tends to overestimate the RR for common diseases.

Explanation:

The term AOR refers to the Adjusted Odds Ratio, which is a statistical measure used to describe the strength of association or non-independence between two binary data values in epidemiology and other fields. In comparison to the Relative Risk (RR), the AOR is a more complex measure that takes into account additional variables that may affect the outcome. In the context of disease prevalence, when a disease is uncommon (around 5% prevalence or less), the AOR can closely approximate the RR. However, for more common diseases (for example, with a 40% prevalence of hypertension), the odds ratio tends to overestimate the risk compared to the RR, diverging more as the prevalence increases.

- The vector a is <3 , -2>

- The vector b is <-2 , 5>

* We can add and subtract the vectors

∵ a = <3 , -2>

∵ b = <-2 , 5>

- To find b - a subtract a from b

∴ b - a = <-2 , 5> - <3 , -2> = <(-2 - 3) , (5 - -2)> = <(-5) , (7)>

∴ The resulting vector b - a is <-5 , 7>

∵ a = <3 , -2>

∴ 2a = <(2 × 3) , (2 × -2) = <6 , -4>

* Now lets find the resulting vector 2a - b

- Subtract b from 2a

∵ 2a = <6 , -4>

∵ b = <-2 , 5>
