Answer:

Picture 1: 40 degrees

Picture 2: 90 degrees

Picture 3: 65 degrees

Picture 4: 85 degrees

Step-by-step explanation:

(2x-5) + (x+25) + (x) = 180

4x=160, x=40

180-90 = 90

2(65)+12+38 = 180

2x=40, x=20

6(20)-25 = 95

180-95 = 85

Answer:

450 sq feet.

Step-by-step explanation:

L x W = A

L = 15

W = 30

15 x 30 = 450

Therefore, Kevin will need 450 sq feet (150 sq yards) of carpet to completely cover the floor.

Hope this helps!

Answer:

65.8

Step-by-step explanation:

(2.6*4.7)/2=6.11

11*4.7=51.7

(4.7(17-(2.6+11)))/2=7.99

6.11+51.7+7.99=65.8

Answer:

5^15

Step-by-step explanation:

5^5 is 3125, and 5^10 is 9765625. When multiplied, you get 30517578125. 5^5 is in the equation, so that couldn't be the answer. 5^50 is too big of a number, so that also wouldn't work. 5^2 is 25, and that would be too small. That leaves 5^15, which when calculated leads to 30517578125.

Answer:

5^15

Step-by-step explanation:

5^10 is equivalent to 9765625 and 5^5 is equivalent to 3125. 9765625x3125 is equal to 30517578125. We need to find the expression wich is equal to that number. It can't be 5^2 (25), 5^5 (3125), 5^50 (8.8817842e+34). The answer is 5^15 (30517578125)

Given :

A hostel of 500 boys has provisions for 4 days.

To Find :

If the provisions were continued for  20 days, how many students have gone out of the hostel.

Solution :

Let, number of students left after 20 days are x.

Now, provisions are given by :

[tex]\text{Provisions = Number of students}\times \text{Number of days}[/tex]

Also, provisions remains same.

So, initial provision = final provision

[tex]500\times 4 = x \times 20\\\\x=100[/tex]

Therefore, 100 students have gone out of the hostel.

Hence, this is the required solution.

Answer:

M(6,3)

Step-by-step explanation:

Find the average of your x1 and x2 and your y1 with your y2.

Don't change which ordered pair is 1 or 2.

so:

U(2,3)

V(10,3)

M(x,y)

x= (2+10)÷2=(12)÷2=6       X=6

y=(3+3)÷2=6÷2=3             Y=3

Answer:

[tex]\large \boxed{\sf h= \frac{S-2\pi r}{2\pi r} }[/tex]

Step-by-step explanation:

The surface area of a cylinder:

[tex]S=2\pi r h + 2\pi r[/tex]

Solve for height h

Subtract 2πr  from both sides

[tex]S-2\pi r=2\pi r h[/tex]

Divide both sides by 2πr

[tex]\displaystyle \frac{S-2\pi r}{2\pi r} = h[/tex]

Step-by-step explanation:

a. y = 2 + 4.3(-6)

y= 2- 25.8

y= -23.8 or y= -24

b. y= (9-3)2

18-6=12

c. y= 3.5-2

y= 1.5

d. y= 5(-2) - 4

y= -10-4

y= -14

Answer:

9.25 or 9 1/4

Step-by-step explanation:

Answer:   -9¼

Step-by-step explanation: -(5¾ - 3½)

Add the whole numbers:  5 + 3 = 8

Combine the fractions: ¾ + ½ = 5/4

Convert improper fraction to mixed number:  5/4 = 1¼

Now, -(8 + 1¼)

Add the numbers 8 + 1 = 9

Then include the fraction:  -9¼

Answer:

[tex]\huge\boxed{(2,4)}[/tex]

Step-by-step explanation:

2x + 5y = 16 ------------------(1)

-5x -2y = 2   ------------------(2)

Multiplying (1) by 5

5(2x+5y) = 16*5

10x+25y = 80 ----------------(3)

Multiplying (2) by 2

2(-5x-2y) = 2*2

-10x - 4y = 4 -----------------(4)

Adding Eq. (3) and (4)

10x + 25y -10x -4y = 80 + 4

25y - 4y = 84

21y = 84

Dividing both sides by 21

y = 4

[tex]\rule[225]{225}{2}[/tex]

Now, Putting y = 4 in Eq. (1)

2x + 5(4) = 16

2x + 20 = 16

2x = 20 - 16

2x = 4

Dividing both sides by 2

x = 2

[tex]\rule[225]{225}{2}[/tex]

Ordered Pair = (x,y) = (a,b) = (2,4)

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!

Answer:

option c is the correct answer

Step-by-step explanation:

∠YXZ+117°=180°

∠YXZ=180°-117°

∠YXZ=63°

63°+36°+∠YZX=180°(sum of angles is 180)

99°+∠YZX=180

∠YZX=180-99

∠YZX=81

Answer:

The steepness of the graph will decrease when the width of the bottle is increased.

Step-by-step explanation:

We are told that a bottle with a height vs. volume graph is created asthe bottle is consistently filled with liquid

Now, from initial conditions, the bottle will be empty and immediately we start putting liquid into the bottle, the graph of height vs volume starts.

Now, this height(H) represents the height of the liquid in the bottle while volume(V) is the volume of liquid in the bottle.

Now, we want to find the correlation between the width of the bottle and the steepness of the graph.

Thus, if we are to increase the width of the bottle, it means we are also increasing the capacity of the bottle which is the volume of the bottle.

What this means is that for us to get to the same height(H) before the increase in bottle width, we will need to pour in a larger volume of liquid(V').

If the extra amount of liquid to be poured is v, then the new volume that will get the liquid to the initial height(H) is;

V' = V_initial + v

The implication of this is that the slope of the graph will decrease.

Thus in terms of the question, the steepness of the graph will decrease when the width of the bottle is increased.
