What is the answer to the problem

Answers

Answer:

7

Step-by-step explanation:

The sum of the measures of the angles inside a triangle is 180°. Therefore, we can create the equation (6x+5)+60+73=180.

Then we simplify:

1. combine like terms. (6x+5)+60+73=6x+5+60+73=6x+138

2. 6x+138=180, -138 to both sides of the equation. the equation becomes 6x=42.

3. /6 to both sides of the equation. we can reach the conclusion that x=7

The sum of the 3 angles in a triangle = 180°

73 + 60 + 6x + 5 = 180
138 + 6x = 180
6x = 42
x = 7

6 is a, 2 is b, and x is c, or the hypotenuse.

Plug in the values

6^2 + 2^2 = x^2

in how many ways can 4 mangoes and 3 apples be distributed among 7 children if each child receives only 2 fruit?​

Answers

solution

this is what I did. total number of ways without any restriction =900. we have to subtract the case when at least one child doesn't get any fruit. let that be C1∪C2∪C3 and we use the principle of mutual inclusion and exclusion to find that. C1∪C2∪C3=C1+C2+C3−(all two intersections)+3 intersections (no one gets a fruit case) =3⋅60−3+1=178 so case where each child gets at least one fruit =900−178=722.

The wedge is one-eighth of the wheel of cheese. A cylindrical-shaped wheel of cheese has a radius of 3 inches and height of 1 inch. A wedge of cheese is sliced from the whole. a. Find the surface area of the cheese before it is cut, round to the nearest hundredth. The surface area of the cheese before it is cut is in. $^2$ . b. Find the surface area of the remaining cheese after the wedge is removed, round to the nearest hundredth. The surface area of the remaining cheese after the wedge is removed is about square inches. Question 2 Did the surface area increase, decrease, or remain the same

Answers

Answer:

1. a. 75.39 in² b. 65.97 in²

2. Decreased

Step-by-step explanation:

1.

a. Find the surface area of the cheese before it is cut, round to the nearest hundredth.

Since the cheese is a cylinder with radius, r = 3 inches and height, h = 1 inch, its tital surface area, A = 2πr(r + h)

Substituting the values of the variables into the equation, we have

A = 2πr(r + h)

A = 2π(3 in)(3 in + 1 in)

A = (6π in)(4 in)

A = 24π in²

A = 75.39 in²

b. Find the surface area of the remaining cheese after the wedge is removed, round to the nearest hundredth.

Since the area of the wedge, A' is one-eight the area of the cheese, A

A'= A/8

= 75.39 in²/8

= 9.42 in²

The area of the remaining cheese is thus, area of cheese - area of wedge  = A - A' = 75.39 in² - 9.42 in² = 65.97 in²

Question 2 - Did the surface area increase, decrease, or remain the same

Since the area of the remaining cheese, A' = 65.97 in² < A = 75.39 in², area of original cheese, the surface area decreased.

It costs $5 to ship a text from Novato to San Francisco, but it costs $10 to ship it to Sacramento. It costs $15 to ship a text from Lodi to San Francisco, but it costs $4 to ship it from Lodi to Sacramento. How many copies should the company ship from each warehouse to San Francisco and Sacramento to fill the order at the least cost

Answers

Answer:

Ship : 600 copies from Novato and 400 copies from Lodi to fulfill order at least cost ( $4600 )

Step-by-step explanation:

Order size :

600 Copies of texts from San Francisco and

400 Copies of texts from Sacramento.

Available notes in the company

700 copies of texts in Novato

800 copies of texts  in Lodi

Cost of sending copies of texts

Novato to San Francisco = $5

Novato to Sacramento = $10

Lodi to San Francisco = $15

Lodi to Sacramento = $4

considering Novato

700 copies are available hence the the least cost will be

600 * $5 ( to Francisco ) = $3000

considering Lodi

800 copies are available hence the least cost will be

400 * $4 ( to Sacramento ) = $1600

Therefore the least cost = $3000 + $1600 = $4600

An equilateral triangle has a side length of 10 units. What is it’s area?

Answers

Answer:

[tex]25\sqrt{3}=43.3\ \mathrm{units}[/tex]

Step-by-step explanation:

Area of a triangle = [tex]\frac{1}{2}ab\textrm{sin}(\theta)[/tex] where [tex]a[/tex] and [tex]b[/tex] are the sides of the triangle and [tex]\theta[/tex] is the angle between those two sides.

The side length are 10, and since its an equilateral triangle, the angle is 60 degrees. Thus, the area becomes [tex]\frac{1}{2}(10)(10)\textrm{sin}(60)=25\sqrt{3}=43.3\ \mathrm{units}[/tex]

9 km/h or 48 km/h

Step-by-step explanation:

Let the distance is d, speed is s

As per given we have:

d/s = 536/s + (d - 36)/(s + 3) = 5 - 1/4

Substitute d with 5s and solve for s:

36/s + (5s - 36)/(s + 3) = 19/436(s + 3) + s(5s - 36) = 19s(s + 3)/44(36s + 108 + 5s² - 36s) = 19s² + 57s20s² + 432 = 19s² + 57ss² - 57s + 432 = 0s² - 9s - 48s + 432 = 0s(s - 9) - 48(s - 9) = 0(s - 9)(s - 48) = 0s -9 = 0 ⇒ s = 9 km/hs - 48 = 0 ⇒ s = 48  km/h

Step-by-step explanation:

Given:  In the beginning, the sunflower was 20 inches tall.

The sunflower then began to grow at a rate of 1.5 inches per week.

Then, total height of sunflower in 4 weeks = 10+1.5 ×10, where 1.5 ×10= growth in 4 weeks

= 20+20 = 40 inches
