Answer:

51cm^2

Step-by-step explanation:

The formula for the area of a parallelogram is : [tex]base*height[/tex]

To work out the area of a parallelogram you would simply multiply the base of 8.5 by the height of 6, this gives you 51cm^2. This is because the formula for the area of a parallelogram is base multiplied by the height.

1) Multiply 8.5 by 6.

[tex]8.5*6=51cm^2[/tex]

Answer:

C = 2*3.14*10 = 62.8 cm = P of square

Area=1/16 * p2

=

246.49 cm2

Answer & Step-by-step explanation:

y = 2x - 3

-x - 8y = 7

Since, we have a equation for y, then we can substitute this equation for y to solve for x.

-x - 8(2x -3) = 7

-x - 16x + 24 = 7

-17x + 24 = 7

-17x = -17

x = 1

So, since we know that x is equal to 1, then we can plug in this number for the equation of y to find y.

y = 2(1) - 3

y = 2 - 3

y = -1

So, the solution is (1, -1). X equals 1 and y equals -1.

Answer: 48, 52

Step-by-step explanation:

The sum of the two numbers (x, y) is 100. This means that;

x+y=100

Their difference is 4, so;

y=x+4

Now, you can substitute that in for y;

x+(x+4)=100

Simplify;

2x+4=100

2x=96

x=48

Now, we plug in the value of x to the second equation;

y=48+4

y=52

Answer:

48 and 52

Step-by-step explanation:

We have a pair of simultaneous equations and will solve these using substitution.

x + y = 100 (1)

x - y = 4 (2)

Solve for x:

x+y=100 , x - y = 4

x=52

Substitute x with 52

(52) + y = 100  , (52) - y = 4

Simplify:

y = 48

Answer:

36.5625 cm^2

Step-by-step explanation:

To find volume, you multiply the three dimensions.

Answer:

36.56 cu. cm

Step-by-step explanation:

Volume = base x height x length

Answer:

To calculate the balance after 6 years with monthly compounding, we can use the formula for compound interest:

A = P * (1 + r/n)^(n*t)

Where:

A = the final amount (balance) after t years

P = the principal amount (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times interest is compounded per year

t = the number of years

In this case:

P = $1500

r = 4% = 0.04 (as a decimal)

n = 12 (compounded monthly)

t = 6 years

Plugging in the values, we get:

A = 1500 * (1 + 0.04/12)^(12*6)

Calculating the right-hand side:

A = 1500 * (1 + 0.003333)^72

A = 1500 * (1.003333)^72

A ≈ 1500 * 1.265032

A ≈ $1897.55

Therefore, the balance after 6 years with monthly compounding, rounded to the nearest cent, is approximately $1897.55.

Answer:

Step-by-step explanation:

The Standard Deviation is defined as

[tex]\sigma =\sqrt{\frac{\Sigma (x_{i} -\mu)^{2} }{N-1} }[/tex]

Where [tex]\sigma[/tex] is the standard deviation, [tex]\mu[/tex] is the mean and [tex]N[/tex] is the total number of data.

So, first, we need to find the mean of the data set.

[tex]\mu = \frac{10+11+12+10.5+11.25+12.25+10}{7} =11[/tex]

Now, we have to subtract each data with the mean to then elevate the differnece to the square power.

[tex]10-11 = -1 \implies (-1)^{2}=1\\ 11-11 = 0 \\12-11 = 1 \implies 1^{2}=1\\ 10.5-11 = -0.5 \implies (-0.5)^{2} =0.25\\11.25 - 11 = 0.25 \imples (1.25)^{2}=0.0625\\12.25 - 11 = 1.25 \implies (1.25)^{2}=1.5625\\10-11 = -1 \implies (-1)^{2}=1[/tex]

Then, we sum all these results.

[tex]\Sigma (x_{i}- \mu )^{2}=1+0+1+0.25+0.0625+1.5625+1=16.278[/tex]

Next, we divide the sum by [tex]N-1=7-1=6[/tex]

[tex]\frac{\Sigma (x_{i}-\mu )^{2} }{N-1}=\frac{16.278}{6} \approx 2.713[/tex]

Finally, we apply the square root.

[tex]\sigma = \sqrt{2.713} \approx 1.65[/tex]

Therefore, the standard deviation for the given data set is 1.65.

Answer:

The angle is 36.87°

Step-by-step explanation:

To find the missing angle, we will have to use inverse SOH-CAH-TOA.

Looking at the angle, as well as the two sides, we can infer that the opposite of the unknown angle is 24. Since the given side is not the hypotenuse but the adjacent, we know that we will be using inverse tangent (TOA).

[tex]tan^{1}[/tex] (x) = [tex]\frac{24}{32}[/tex]

x = [tex]tan^{-1}[/tex] ([tex]\frac{24}{32}[/tex])

x = 36.87°

Answer:

≈ 36.9

Step-by-step explanation:

You are given the opposite and adjacent side, leading you to use tan. However, since you're trying to find the angle measurement, and not the side, you use the inverse of tan: [tex]tan^-1[/tex]

Set it up like this:

[tex]tan^-1 (\frac{24}{32})=?[/tex]

When you solve, you get:

36.86

Round to the nearest tenth:

36.9

So the right answer is 71 degree

Answer:

c

Step-by-step explanation:

did the exam on edge and got 100

The slope is Negative two-fifths, and the y-intercept is Negative one-third. Hence, the correct option is A.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The slope of the linear function that is represented by the table,

Slope, m = [(-3/5) - (-13/30)]/[(2/3)-(1/4)]

= [(-18+13)/30] / [(8-3)/12]

= -(12/30)

= -(2/5)

The y-intercept of the linear function that is represented by the table can be found by substituting the coordinate of any one point in the equation of the line.

[tex]y = mx + c\\\\-(\dfrac{2}{15}) = -(\dfrac{2}{5})(-\dfrac12) + C\\\\-\dfrac{2}{15} = \dfrac15 + C\\C = -\dfrac5{15}\\\\C = -\dfrac13[/tex]

Hence, The slope is Negative two-fifths, and the y-intercept is Negative one-third. Hence, the correct option is A.
