Answer: 2.11cm

Step-by-step explanation:

Given the following :

The lengths of the parallel sides are (2z + 3) cm and (6z – 1) cm

The area of trapezoid is calculated using the formula:

1/2(a + b) × h

Where ;

a = Length of side 1

b = length of side 2

h = height

Take a = (2z + 3) and b = (6z – 1), h = z

Therefore ;

1/2 (2z + 3 + 6z - 1) × z

Opening the bracket

(z + 1.5 + 3z - 0.5) × z

(4z + 1 ) × z = 20cm^2

4z^2 + z = 20cm^2

Using Quadratic formula:

4z^2 + z - 20 = 0

a = 4, b = 1, c = - 20

(-b±√b^2 -4ac) / 2a

Z = 2.11 or - 2.364

z cannot be negative, therefore,

Z = 2.11 cm

Answer: No solution

Both tables have slope 2 (y increases two for every increase of 1 in x).  First has y intercept 5, second 15  (19=2(2)+b).  So our system is

y = 2x + 5

y = 2x + 15

Those are parallel lines, which never meet, so no solution.

Answer:

~120.4 cm

Step-by-step explanation:

Applying the Pythagorean theorem:

height^2 + 127^2 = 175^2

=> height^2 = 175^2 - 127^2

=> height^2 = 14496

=> height = sqrt(14496) = ~120.4 cm

Answer:

The measure of angle P is 43°

Step-by-step explanation:

If a quadrilateral is inscribed inside a circle, the sum of opposite angles are always equal to 180 degrees.

The angle POR is opposite to the angle PQR, and the angle OPQ is opposite to the angle ORQ.

So we have that:

mOPQ + mORQ = 180°

y + 3y + 8 = 180

4y = 172

y = 43°

So the measure of angle P is 43°.

Answer:

Pennies = 80

Nickels = 160

Step-by-step explanation:

Two equations representing the relation between numbers of pennies and nickels have been given.

0.01p + 0.05n = 8.80 ---------(1)

n = 2p -----(2)

By substituting the value of n from equation (2) in equation (1).

0.01p + 0.05(2p) = 8.80

0.01p + 0.1p = 8.80

0.11p = 8.80

p = [tex]\frac{8.8}{0.11}[/tex]

p = 80

By equation (2)

n = 2×80

n = 160

Answer:

smaller x = -2

larger x = 4

vertex: (1, -9)

Step-by-step explanation:

To find the zeros of the function, set each value in parenthesis to 0 separately.

Smaller x:

(x+2) = 0

x = -2

Larger x:

(x-4) = 0

x = 4

To find the vertex of the parabola you need to find the x value between the zeros.

[tex]\frac{4 + (-2)}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

Plug 1 in for x in the equation.

f(x) = ((1) + 2)((1) - 4)

f(x) = (3)(-3)

f(x) = -9

When x = 1, f(x) = -9, so the vertex of the parabola is at (1, -9).

Answer:

Alcohol

Step-by-step explanation:

Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.

Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.

(x-3)^2 = 4

Step-by-step explanation:

2 ( x-3) ^2 +6 = 14

Subtract 6 from each side

2(x-3)^2 = 8

Divide each side by 2

(x-3)^2 = 4

Take the square root of each side

x-3 = ±2

Add 3 to each side

x = 3±2

Answer:

a. 452.4 cm³ to the nearest tenth b. 113.1 cm³ to the nearest tenth

c. 5.0 cm to the nearest tenth

Step-by-step explanation:

a. The volume of the water V₁ = πr²h since it is in a cylindrical container. r = 6 cm and h = 10 cm - 6 cm = 4 cm (since it is filled to a depth of 6 cm measuring from the top, so we have a height from the bottom of 10 cm - 6 cm = 4 cm).

So, V₁ = πr²h

= π × (6 cm)² × 4 cm

= 452.39 cm³

= 452.4 cm³ to the nearest tenth

b. The volume of the sphere V₂ = 4πr³/3 where r = radius of sphere = 3 cm.

V₂ = 4πr³/3

= 4π(3 cm)³/3

= 113.1 cm³ to the nearest tenth

c. When the sphere is placed in the container, the new volume of water in the container would be V = V₁ + V₂

So V = 452.4 cm³ + 113.1 cm³ = 565.5 cm³

Since the volume of water is still the volume of a cylinder, its height h is

h = V/πr²

= 565.5 cm³/π(6 cm)²

= 5.0 cm to the nearest tenth

Answer:

-n-2

Step-by-step explanation:

First, you need to distribute the 2 on the -2n and -1. So multiply the 2 by -2n and -1. You get = -4n-2.

You still have the 3n, so the equation will now look like: 3n-4n-2.

Combine like terms. 3n-4n= -1n or just -n.

Now you have -n-2.

Answer:

XZ = 16.25 cm

QR = 6.8 cm

Step-by-step explanation:

A) Taking the proportion of similar sides

=> [tex]\frac{7.2}{6.5} = \frac{18}{XZ}[/tex]

Cross Multiplying

=> 7.2 XZ = 18*6.5

=> XZ = 117/7.2

=> XZ = 16.25 cm

B) Taking proportion of similar sides

=> [tex]\frac{18}{17}=\frac{7.2}{QR}[/tex]

Cross Multiplying

=> 18 QR = 17*7.2

=> QR = 122.4/18

=> QR = 6.8 cm

Complete Question

Fifteen percent of the students at Central High take Spanish, 12% take French, and 4% take both. If a student is selected at random, what is the

probability that the student takes Spanish or French?

A 31%

B. 27%

C. 23%

D. 19%

Answer:

C. 23%

Step-by-step explanation:

At Central High

From the question, we are told that:

Spanish = 15%

French = 12%

Spanish and French = 4%

French or Spanish = unknown

Therefore, the probability that a student at random takes Spanish or French

= P(Spanish) + P(French) - P(Spanish and French)

= 15% + 12% - 4%

= 27% - 4%

= 23%

Step-by-step explanation:

4x+2y=4

4×x+2×6=4

4x+ 12=4

4x=12-4

4÷4x=8÷4
