Answer:

  E.  40 and 33

Step-by-step explanation:

The Pythagorean theorem tells you the sum of the areas of the smaller squares will match the area of the largest square.

The answer choices have sums of ...

  A: 76; B: 73; C: 96; D: 66; E: 73

So, choices with the correct sum are B and E.

If this question asks you to "choose all that apply," then B & E will be your answer choices.

__

We note that the areas of the smaller squares appear to be not much different in size. If their areas were 23 and 50, the smaller square would be less than half the size of the larger one. So, if the figure is drawn approximately to scale, the choice of 40 and 33 is a better choice.

Answer: A 2(2cos^2(x) - 1)^2 - 1

Step-by-step explanation: E 2020

The expression equivalent to cos(4x) is 2cos²(2x) - 1.

Out of the options provided, the correct choice is 2cos²(2x) - 1.

The expression equivalent to cos(4x) can be found using trigonometric identities and formulas. One such identity is the double angle identity for cosine:

cos(2θ) = 2cos²(θ) - 1.

We can apply this identity to the expression cos(4x) by considering it as cos(2(2x)).

Using the double angle identity, we have:

cos(4x) = cos(2(2x)) = 2cos²(2x) - 1.

Therefore, the expression equivalent to cos(4x) is 2cos²(2x) - 1.

Out of the options provided, the correct choice is:

O 2cos²(2x) - 1.

By substituting 2x for θ in the double angle identity, we obtain the equivalent expression for cos(4x).

Answer:

Hope it helps

Step-by-step explanation:

So you want to get x by itself.

x3= [tex]\frac{64}{27}[/tex]

You could simplify

x3=2.37037037037

Then just divide 3 on both sides

x=0.79012345679

Or you can divide a fraction by a whole number and just divide the numerator and the denominator by 3.

x= [tex]\frac{21.3}{9}[/tex] or just 2.36666666667.

Answer:

r≤0

Step-by-step explanation:

if the range is s≤0, (that means the value of s is all negative integers &0) to find the domain we have to replace that some negative integers &0.

we can replace some values of s as the following

s=‒4(0)^2 s=‒4(‒1)^2

=‒4(0) =‒4(1)

=0 =‒4

s=‒4(‒2)^2 s=‒4(‒3)^2

=‒4(4) =‒4(9)

=‒16 =‒36

so we can understand easly that the domain is negative integer&0,it can't be positive because the square of any integer is positive.

therefore the answer is r≤0

i think &i hope it is clear.

The domain is the set of values for which the given function is defined. The domain of the function s=-4r² if the range is s≤0 is r∈R. The correct option is B.

For the given function s=-4r², the domain of the function when s≤0 will be all the real numbers. This is because, for any value of r whether it is positive or negative, the value of r² will be positive, but at the same time this quantity is needed to be multiplied by -4.

Thus, the result of -4r² will be always negative, which is less than zero.

Hence, the domain of the function s=-4r² if the range is s ≤0 is r∈R.

Answer:

It is the MEAN

Step-by-step explanation:

Mean, median and mode given in the question are all used to measure central tendency of a given data. From the sets of data given, and from the values of the mean, median and mode (8.8, 8.85 and 8.9 respectively) it can be summarized that these values points the center of the sets of data trying to estimate the average.

MEAN is the statistic that reflects a typical score because when we look at the data (8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2), it easily gives us the average score. Since mean = addition of the data value / the number of the data, it gives us Kathleen average score since it takes all the  judges scores into consideration giving us the typical score. Unlike mode that only use most occured data meaning it doen't use all the data and as such may not show the true average of the scores. Also, mode is not consistent when it comes to small number of data especially if no score occur most or we have more than one mode. It is not median because of the small number of scores (data).

Answer:

Number of yards per day = 20.83 yard (Approx)

Step-by-step explanation:

Assume;

Number of yards = x per day

Number of yards on 6th day = x + 8

Total yards = 133

Find:

Number of yards per day

Computation:

Total yards = 5[x] + x + 8

133 = 6x + 8

6x = 125

x = 20.83 yard

Number of yards per day = 20.83 yard (Approx)

Answer:

20.83 yards

Step-by-step explanation:

Calculate Cubic Yards

Calculate your area

Calculate your volume: Multiply area times the depth to get volume in cubic feet

Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer

Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard

Total yards = 5[x] + x + 8  

Solve

133 = 6x + 8

6x = 125

x = 20.83 yard

Therefore, the Cyclone cleared 20.83 yards on the first day.

Number of M&M bags with Danielle = 24

Number of jelly beans with her = 36

Number of snickers with her = 48

To find the highest number of candies each friend of Danielle will get, in a way in which all of them have the same number of candies , we have to find the HCF (highest common factor) of all the varieties of candy with Danielle.

Factors of 24 = 1,2,3,4,6,8,12,24

Factors of 36 = 1,2,3,4,6,9,12,18,36

Factors of 48 = 1,2,3,4,6,8,12,16,24,48

Highest common factor = 12

Which means the highest number of friends Danille can invite is 12 .

Number of M&M bags each friend will get :-

[tex] = 24 \div 12[/tex]

[tex]\color{hotpink} = 2 [/tex]

Which means each friend will get 2 M&M bags .

Number of jelly beans each friend of hers will get :-

[tex] = 36 \div 12[/tex]

[tex]\color{hotpink} = 3[/tex]

Which means each friend of Danielle will get 3 jelly beans.

Number of snickers each friend of hers will get :-

[tex] = 48 \div 12[/tex]

[tex] \color{hotpink}= 4[/tex]

Which means each friend of hers will get 4 snickers .

Therefore , the highest number of friends Danielle can invite = 12 and each of her friends will get 2 M&M bags , 3 jelly beans and 4 snickers .

Answer:

d = 4

Step-by-step explanation:

First, we take the equation 2d = 8

In order to find out what the value of 9 must be in order to make this equation true, we must isolate the variable. That can be done by doing the opposite operation. In this case, the opposite operation would be division since d is being multiplied by 2 to get 8.

So, we have to divide both sides of the equation by 2:

2d = 8

2      2

2d divided by 2 is equal to d.

And 8 divided by 2 is equal to 4.

Therefore, d is equal to 4.

Answer:

angle 8 and angle 5

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use the slope formula:

[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]

where m = slope

(-5, 0) -> means x1 = -5. y1 = 0

(7, 8) -> means x2 = 7 , y2 = 8

Substitute these values into the slope formula above and you get:

[tex]m = \frac{y2 -y1}{x2 - x1} = \frac{8-0}{7- (-5)} = \frac{8}{7+5} = \frac{8}{12} = \frac{2}{3}[/tex]

The slope of the line that passes through the points (-5,0) and (7,8) is 2/3

The formula for calculating the slope of a line is expressed as:

[tex]m = \frac{y_2-y_1}{x_2-x_1} \\m=\frac{8-0}{7-(-5)} \\m=\frac{8}{7+5}\\m=\frac{8}12} \\m= \frac{2}{3}\\[/tex]

Hence the slope of the line that passes through the points (-5,0) and (7,8) is 2/3

Answer:

equation: y=-7.5x+15 and Raul must ride at a speed of 5 mi/hr

Step-by-step explanation:

[tex]\frac{y2-y1}{x2-x1}[/tex] to find out the slope. [tex]\frac{6-11.25}{1.2-0.5}[/tex]=[tex]\frac{-5.25}{0.7} = -7.5[/tex]

Then you fill x and y to find out the y intercept

[tex]11.25=-7.5*0.5+b[/tex]

[tex]11.25=-3.75+b\\11.25+3.75=15\\[/tex]

Y intercept= 15

then you put it in the equation:

y=-7.5x+15

Since Raul lives 5 miles closer and Luis is 5 miles away, he needs to go at 5 miles an hour to get to the spot.

That is 5 miles/hour

The distance and time, as presented in this question are illustrations of linear equations.

From the diagram, we have:

[tex](x_1,y_1) = (0.5,11.25)[/tex]

[tex](x_2,y_2) = (1.2,6)[/tex]

Start by calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{6 - 11.25}{1.2 - 0.5}[/tex]

[tex]m = \frac{-5.25}{0.7}[/tex]

[tex]m = -7.5[/tex]

The equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives

[tex]y = -7.5(x - 0.5) + 11.25[/tex]

[tex]y = -7.5x + 3.75 + 11.25[/tex]

[tex]y = -7.5x + 15[/tex]

Calculate distance, when [tex]x = 5[/tex]

We have:

[tex]y = -7.5 \times 5 + 15[/tex]

[tex]y = -22.5[/tex]

The speed (s) is then calculated as:

[tex]s = \frac{22.5}{5}[/tex]

[tex]s = 4.5[/tex]

Hence, he must plan to ride at 4.5 miles per hour
