Step-by-step explanation:

The average of 5 numbers is 23. If the 4 numbers are 18, 27,22 and 20 then find the 5th number?

Answers

Answer:

5th number = 28

Step-by-step explanation:

23*5 = 115

The sum of the 5 numbers is

115

Then:

18 + 27 + 22 + 20 + a = 115

a = 5ft number

87 + a = 115

a = 115 - 87

a = 28

Check:

(18+27+22+20+28)/5 = 23

115/5 = 23

Answer: The fifth number is 28

Step-by-step explanation:

All numbers = 18, 27, 22, 20, x

5th number is x


So,  [tex]\frac{18+27+22+20+x}{5}[/tex]  = 23  (as the there are 5 numbers)

=> [tex]\frac{87+x}{5}[/tex] = 23

=> 87+x = 115

=> x = 28

Therefore the 5th number is 28

20:60

12:36

2:6

there r other ways you can do it tho :)

Answer: 20:60, 12:36, 2:6.

Step-by-step explanation: 4:12 = 1:3. The ratio 4:12 is equal to 1:3. which means that the second number (sn) is 3 times the first number (fn). sn = 3 * fn. The first equation: sn = 3 * 20. 3 * 20 is 60, so the second number would be 60. The second equation: 36 = 3 * fn. Divide each side by three, so the equation reads 12 = fn. The last equation: 6 = 3 * fn. Divide each side by three, so the equation reads 2 = fn.

can anyone help me get these answered? (how to solve it and the answer)

Answers

A way I have learned to solve these is by doing is over of

is
—
of

for example, what percent of 60 is 57

57 x
— x —
60 100

now what you do is cross multiply. 57x100=5,700
60 • x = 60x
60x=5,700
——————
60

the answer for the first question is 95, so the answer is 95%.

If you need the other questions done just tell me!
60x57/100%=34.2%

The perimetre of a rectangle is 38cm length is 12.5, What is the Area?...

Answers

Answer:

A=81.25cm,B=6.5cm

Step-by-step explanation:

P=38cm

L=12.5cm

B=?

P=2(L+B)

P=2L+2B

38=2(12.5)+2B

38=25+2B

C.L.T

2B=38-25

2B=13

divide both sides by 2

B=6.5cm

therefore

A=?

L=12.5cm

B=6.5cm

so,

A=12.5cm×6.5cm

A=12.5×6.5 ×cm×cm

A=81.25×cm²

A=81.25cm²

∠a and ∠b are complementary. Find the value of∠b when ∠a is 72°
THANK YOU SO MUCHHHH!!

Answers

Step-by-step explanation:

Complementary angles sum to 90°

a + b = 90

72 + b = 90

b = 90 -72

b = 18°

When two angles are complementary, it means that the two angles add up to 90°. Thus when angle a is 72° when angle a and angle b are complementary,

angle a + angle b = 90°
72° + angle b = 90°

*minus 72° on both sides of the eqn*

angle b= 90°-72°
angle b= 18°

The ages of a group of lifeguards are listed.

17, 17, 18, 19, 22, 23, 25, 27, 32, 38

If another age of 33 is added to the data, how would the mean be impacted?

The mean would increase in value to about 24.6.
The mean would increase in value to about 27.1.
The mean would stay the same value of about 22.5.
The mean would stay the same value of about 23.8.

Answers

The correct answer is B. The mean would increase in value to about 27.1
If another age of 33 is added to the data, the new mean would be (17 + 17 + 18 + 19 + 22 + 23 + 25 + 27 + 32 + 38 + 33) / 11 = 27.1.

Step-by-step explanation:

the mean would increase to about 24.6 is the answer

if u add all the ages together including the extra 33 you get 271. if u divided this by 11 you get 24.636...

A bullet train covers 895.65km in 5 hours. What distance will it cover in an hour?

Answers

Answer:

179.13km/1hr (or 179.13 km)

Step-by-step explanation:

Distance is speed/time.

Using that, we can input

895.65 KM / 5 H

To convert 5 hours to one hour to find the speed, we need to divide both 5 and 895.65 by 5:

179.13km/1hr

which is your answer :)

Step-by-step explanation:

5 hours = 895.65km

Let 1hrs = x

:895.65/5 = x

=179.13= x

so, therefore 1hours bullet train covers 179.13km

Select TWO equations that have the same value of p when solved.
1) p+5=6
2) 2(p+2)=3
3) 0.2p−8=8.2p
4) 8p−12=−4
5) p+4=2p

Answers

Answer:

1,5

Step-by-step explanation:

Equations 1 and 5 have the same value of p when solved.

p+5=6 can be solved as:

p = 6 - 5 = 1

p+4=2p can be solved as:

p = 4

Answer:
1 and 4 solve to p = 1

Step by step solved:

To find which equations have the same value of p when solved, we need to solve each equation for p and compare the solutions.

1) p+5=6
Subtracting 5 from both sides:
p+5-5=6-5
p = 1

2) 2(p+2)=3
Distributing the 2:
2p + 4 = 3
Subtracting 4 from both sides:
2p = -1
Dividing both sides by 2:
p = -1/2

3) 0.2p−8=8.2p
Subtracting 0.2p from both sides:
-7.8p - 8 = 0
Adding 8 to both sides:
-7.8p = 8
Dividing both sides by -7.8:
p = -1.0256

4) 8p−12=−4
Adding 12 to both sides:
8p = 8
Dividing both sides by 8:
p = 1

5) p+4=2p
Subtracting p from both sides:
4 = p
So the equations that have the same value of p when solved are:

1) p+5=6 and 4) 8p−12=−4, both solve to p = 1

The answer is -5 AKA letter B

Answer: "B. -5"

Step-by-step explanation:

STEP 1: Plug -5 into the equation where "X" currently is; 10 (-5) - 5 = -55

STEP 2: Multiply 10 (-5) [-50].

STEP 3: Update the equation to reflect Step 2; -50 - 5 = -55

STEP 4: Subtract 5 from -50 [-55].

STEP 5: Update the equation to reflect Step 4; -55 = -55

It is true that -55 = -55, so, therefore, the answer is "B. -5."
