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

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.

∠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°

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 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

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."

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

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
