Answer:

what are the phrases to choose from?

Step-by-step explanation:

The solutions to the equations are:

x = 21,

x = 7,

4 * 7 = 28,

3³ - 2³ = 19, and 30 - 2 = 28.

We have,

x + 7 = 28

To solve for x, we can subtract 7 from both sides of the equation:

x + 7 - 7 = 28 - 7

x = 21

So, the solution to the equation x + 7 = 28 is x = 21.

2x + 14 = 28

To solve for x, we can subtract 14 from both sides of the equation:

2x + 14 - 14 = 28 - 14

2x = 14

Next, we divide both sides of the equation by 2 to isolate x:

2x/2 = 14/2

x = 7

Therefore, the solution to the equation 2x + 14 = 28 is x = 7.

4 * 7 = 28

This equation is already solved.

The product of 4 and 7 is 28.

So, the equation 4 * 7 = 28 is true.

3³ - 2³ = 28

To solve this equation, we need to evaluate the exponentials:

3³ - 2³ = 27 - 8 = 19

Therefore, the equation 3³ - 2³ = 28 is not true; the correct value is 19.

30 - 2 = 28

This equation is already solved.

The difference between 30 and 2 is indeed 28.

So, the equation 30 - 2 = 28 is true.

Thus,

The solutions to the equations are:

x = 21,

x = 7,

4 * 7 = 28,

3³ - 2³ = 19, and 30 - 2 = 28.

Answer:

The numbers are 18, 13, and 72.

Step-by-step explanation:

Let the three numbers be represented by a, b, and c.

The sum of the three is 103. Thus, we can write that:

[tex]a+b+c=103[/tex]

The second number is five less than the first. So:

[tex]b=a-5[/tex]

And the third number is four times the first. So:

[tex]c=4a[/tex]

Substitute:

[tex]a+(a-5)+(4a)=103[/tex]

Solve for a. Combine like terms:

[tex]6a-5=103[/tex]

Add five to both sides:

[tex]6a=108[/tex]

And divide both sides by six. Therefore:

[tex]a=18[/tex]

So, the first number is 18.

Since the second number is five less than the first, the second number is 13.

And since the third number is four times the first, the third number is 72.

Given:

Radius of the circle = 4 meters

Measure of arc = 135 degrees

To find:

The area of the sector bounded by the given arc.

Solution:

Formula for area of a sector is:

[tex]A=\pi r^2\times \dfrac{\theta}{360^\circ}[/tex]

Where, r is the radius and [tex]\theta[/tex] is the central angle or measure of intercepted arc.

Putting [tex]r=4,\ \theta =135^\circ[/tex] in the above formula, we get

[tex]A=\pi \times (4)^2\times \dfrac{135^\circ}{360^\circ}[/tex]

[tex]A=\pi \times 16\times \dfrac{3}{8}[/tex]

[tex]A=\pi \times 2\times 3[/tex]

[tex]A=6\pi [/tex]

Therefore, the exact area of the given sector is [tex]6\pi [/tex] square meters.

Answer:

23.92°, 78.503°, and 77.577°

Step-by-step explanation:

The coordinates of the vertices of the triangle are;

X(-3, -5), Y(2, 6), Z(6, 3)

The vectors are;

z = [tex]\left \langle 2 - (-3), 6 - (-5) \right \rangle[/tex] = [tex]\left \langle 5, 11 \right \rangle[/tex]

y = [tex]\left \langle 6 - (-3), 3 - (-5) \right \rangle[/tex] = [tex]\left \langle 9, 8 \right \rangle[/tex]

x = [tex]\left \langle 2 - 6, 6 - 3 \right \rangle[/tex] = [tex]\left \langle -4, 3 \right \rangle[/tex]

[tex]cos (\alpha ) = \dfrac{z \cdot y}{\left | z \right | \times \left | y \right |}[/tex]

Therefore, we get;

[tex]cos (\alpha ) = \dfrac{5 \times 9 + 11 \times 8 }{\left | \sqrt{5^2 + 11^2} \right | \times \left | \sqrt{9^2 + 8^2} \right |} = \dfrac{133}{\sqrt{146} \times \sqrt{145} } \approx 0.91409[/tex]

α = arccos(0.91490) ≈ 23.92°

γ = The angle between -y and x

-y = [tex]\left \langle -9, -8 \right \rangle[/tex]

We get;

[tex]cos (\gamma) = \dfrac{-y \cdot x}{\left | -y \right | \times \left | x \right |}[/tex]

Therefore;

[tex]cos (\gamma) = \dfrac{-9 \times -4 + -8 \times 3 }{\left | \sqrt{(-9)^2 + (-8)^2} \right | \times \left | \sqrt{(-4)^2 + 3^2} \right |} = \dfrac{12}{\sqrt{145} \times \sqrt{25} } \approx 0.199309[/tex]

γ = arccos(0.199309) ≈ 78.503°

γ ≈ 78.503°

By angle sum property, β = 180° - (α + β)

β ≈ 180° - (23.92° + 78.503°) = 77.577°

β ≈ 77.577°

The interior angles are;

23.92°, 78.503°, and 77.577°

Answer:

3yz² - 3z² - 5y + 7

Step-by-step explanation:

Sum of two polynomials = –yz² - 3z² – 4y + 4

Find the other polynomial

The other polynomial = sum of the polynomials - one of the polynomial

= –yz² - 3z² – 4y + 4 - (y - 4yz² - 3)

= –yz² - 3z² – 4y + 4 - y + 4yz² + 3

= -yz² + 4yz² - 3z² - 4y - y + 4 + 3

= 3yz² - 3z² - 5y + 7

Answer:

17.5 + 15.5

Step-by-step explanation:

17+ 15 = 32

.5 + .5 = 1

32 + 1 = 33

Answer:

15.5 and 17.5

Step-by-step explanation:

Let x and y be the two numbers

x+y = 33

x-y = 2

Add the two equations together

x+y = 33

x-y = 2

-----------------

2x = 35

Divide by 2

2x/2 = 35/2

x = 17.5

Substitute into

x+y = 33

17.5 +y = 33

y = 33-17.5

y = 15.5

Mean score after patient is given the magnet treatment :

Mean score, xbar = 5

Standard deviation, s = 2.4

Mean ± margin of error

Margin of Error = Tcritical * standard error

The critical value at 95%, df = 20 - 1 = 19

Tcritical = 2.093 (T-student distribution)

The standard error = s/√n = 2.4 / √20 = 0.5367

The margin of error = 2.903 * 0.5367 = 1.558

Answer:

43.8°

Step-by-step explanation:

Applying,

Cosine rule,

From the diagram attached,

x² = y²+z²-2yxcos∅.................... Equation 1

where ∅ = ∠YXZ

Given: x = 8.7 m, y = 10.4 m, z = 12.4 m

Substitute these values  into equation 1

8.7² = 10.4²+12.4²-[2×10.4×12.4cos∅]

75.69 = (108.16+153.76)-(257.92cos∅)

75.69 = 261.92-257.92cos∅

collect like terms

257.92cos∅ = 261.92-75.69

257.92cos∅ = 186.23

Divide both sides by the coefficient of cos∅

cos∅ = 186.23/257.92

cos∅ = 0.722

Find the cos⁻¹ of both side.

∅ = cos⁻¹(0.7220)

∅ = 43.78°

∅ = 43.8°

As per linear equation, the average of the student is 82.2.

The mean is 83.75.

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

The student got test average of 80, his quiz average of 72, homework of 90, and classwork of 93.

Test is worth of 30%.

Therefore, the weightage of test is

= 80 × 30%

= 24

Quiz is worth of 30%.

Therefore, the weightage of quiz is

= 72 × 30%

= 21.6

Homework is worth of 20%.

Therefore, the weightage of homework is

= 90 × 20%

= 18

Classwork is worth of 20%.

Therefore, the weightage of classwork is

= 93 × 20%

= 18.6

Therefore, the average of the student is

= (24 + 21.6 + 18 + 18.6)

= 82.2

Now, the mean is

= (80 + 72 + 90 + 93)/4

= 83.75
