Answer:

x = 17

Step-by-step explanation:

all three expressions should be added together and set equal to 180 degrees

6x - 15 + 2x - 2 + 4x - 7 = 180

now combine like terms

12x - 24 = 180

add 24

12x = 204

x = 204/12

x = 17

Answer:

2.25 and 4.95

Step-by-step explanation:

x + y = 7.2

x - y = 2.7

x = 7.2 - y

x - y = 2.7

(7.2 - y) - y = 2.7

7.2 - 2y = 2.7

-2y = 2.7 - 7.2

-2y = -4.5

-2y/-2 = -4.5/-2

y = 2.25

x + y = 7.2

x + 2.25 = 7.2

x = 7.2 - 2.25

x = 4.95

Check: 4.95 and 2.25

x + y = 7.2

(4.95) + (2.25) = 7.2

7.2 = 7.2

x - y = 2.7

(4.95) - (2.25) = 2.7

2.7 = 2.7

Answer:

x+y=7.2

x-y=2.7

Step-by-step explanation:

equation

x+2.7+x=7

2x=4.3

x=4.3/2

y=7-4.3/2

Answer:

Pythagorean Theorem:

a² + b² = c²

x² + 5x² = 78²

6x² = 6084

6x²/6 = 6084/6

x²=1014

√x² = √1014

x = 31.84

Answer:

x ≈ 15.3

Step-by-step explanation:

Based on the pythagoras theorem

[tex]a^{2} + b^{2} = c^{2}[/tex]

Since the legs are "5x" and "x" we know the following....

[tex](5x)^{2} + x^{2} = 78^{2} \\25x^{2} + x^{2} = 6084\\26x^{2} = 6084\\x^{2} = 234\\x = \sqrt{234} \\x = 15.3[/tex]

Answer:

a. 0.57

b. 0.22

c. 0.87

d. 0.9450

Step-by-step explanation:

A.

P(X>=1)

= 0.35 + 0.15 + 0.06 + 0.01

= 0.57

This is the probability of catching one or more fishes.

b.

P(X>=2)

0.15 + 0.06 + 0.01

= 0.22

This is the probability of catching 2 or more fishes.

C.

Compute μ

μ = E(X)

= (0x0.43) + (1x0.35) + (2x0.15) + (3x0.06) + (4x0.01)

= 0+0.35+0.3+0.18+0.04

= 0.87

D.

The standard deviation

Sd = √V(X)

V(X) = E(X²) - (E(X))²

E(X²) = (0²x0.43)+(1²x0.35)+(2²*0.15)+(3²*0.06)+(4²*0.01)

E(X²) = 0.35+0.6+0.54+0.16

= 1.65

V(X) = 1.65 - (0.87)²

= 1.65 - 0.7569

= 0.8931

Sd = √0.8931

= 0.9450

Since X increases by 1,

Divide the 2nd Y value by the first Y value:

Answer:

B. 504 units²

Step-by-step explanation:

We multiply 6 and 8, we don't need to divide by 2 since there are two congruent triangles. That gets us 48. Now, we multiply 19 and 8. That gets us 152. Now, we multiply 6 and 19. That gets us 114. We have found the area of all sides but one. To do this one, we need to calculate the hypotenuse of the triangle. The following screenshot has the formula to calculate hypotenuse. If a is equal to 6, and b is equal to 8, we can do this formula. 6² is 36, and 8² is 64. Now, we add 36 and 64. That gets us 100. The square root of 100 is 10. That means the hypotenuse of this triangle is 10. Now, we multiply 10 and 19 to get 190. Now, we add up the area of all the sides (48 + 152 + 114 + 190). That gets us 504. That means B is our answer.

Answer:

Step-by-step explanation:

u+6 = - 5               Subtract 6

u + 6 - 6 = - 5 - 6

u = - 11

Try thinking this as money. If you are 5 dollars in the hole and you borrow another 6 dollars, where are you?

The answer is that unless you pay your debt of 5 dollars, you are - 11 dollars in the hole.

Answer:

[tex]Cost\ Price = 4331.25[/tex]

Step-by-step explanation:

Given

Selling Price = Sh. 4950

Profit = 12.5%

Required

Determine the cost price

Profit is calculated as:

[tex]Profit = \frac{Selling\ Price - Cost\ Price}{Selling\ Price} * 100\%[/tex]

Substitute values for Selling Price and Profit

[tex]12.5\% = \frac{4950 - Cost\ Price}{4950} * 100\%[/tex]

Cross Multiply:

[tex]4950 * 12.5\% = (4950 - Cost\ Price) 100\%[/tex]

[tex]\frac{4950 * 12.5\%}{100\%} = (4950 - Cost\ Price)[/tex]

[tex]618.75 = (4950 - Cost\ Price)[/tex]

Collect Like Terms

[tex]Cost\ Price = 4950 - 618.75[/tex]

[tex]Cost\ Price = 4331.25[/tex]

Hence, the cost price of the item is: Sh. 4331.25

Answer:

The building is 187.5 feet tall.

Step-by-step explanation:

A nearby person is 6 feet tall, and casts a shadow that is 8 feet long.

This means that the relation between the real height and the shadow is given by:

[tex]\frac{6}{8} = \frac{3}{4}[/tex]

A tall building casts a shadow that is 250 feet long. How tall is the building?*

The real height is three fourths of the shadow. So

[tex]\frac{3}{4}*250 = 187.5[/tex]

The building is 187.5 feet tall.
