z+ 12w when z=8 and w=4

Answer: 6.5 cm

Step-by-step explanation: 1 km = 100,000 cm, so 130 km= 130,000,00 cm, 130,000,00÷2,000,000=6.5 cm

The Charles river will be "6.5 cm" long. A complete solution is provided below.

On the map,

→ 1 : 2,000,000

As we know,

The conversion of kilometer in to centimeter is:

→ [tex]1 \ km = 100,000 \ cm[/tex]

then,

→ [tex]130 \ km= 130,000,00 \ cm[/tex]

hence,

The river will be:

= [tex]\frac{130,000,00}{2,000,000}[/tex]

= [tex]6.5 \ cm[/tex]

Thus the above answer is the appropriate.

0.78 can be written as the fraction 71/90 after simplifying by dividing both the numerator and denominator by the greatest common divisor, which is 0.1.

To rewrite the repeating decimal 0.78 as a simplified fraction, we can use the concept of geometric series.

Let x = 0.78

Multiply both sides by 10 to shift the decimal point:

10x = 7.88

Subtract the original equation from the multiplied equation to eliminate the repeating part:

10x - x = 7.88 - 0.78

This simplifies to:

9x = 7.1

Now, divide both sides of the equation by 9 to isolate x:

x = 7.1/9

To express the fraction in simplest form, we can find the greatest common divisor (GCD) of the numerator and denominator, and then divide both by the GCD:

GCD(7.1, 9) = 0.1

Dividing both the numerator and denominator by 0.1 yields:

7.1/9 ÷ 0.1/0.1 = 71/90

Therefore, the repeating decimal 0.78 is equivalent to the simplified fraction 71/90.

Sunday

Answer:

129:175

Step-by-step explanation:

Andy and Christopher are measuring a liquid solution using a graduated cylinder

Andy uses 3.5 liters of the liquid solution

3.5 liters to mililiters

= 3.5 ×1000

= 3500 mililiters

Christopher uses 2580 mililiters

Therefore the ratio of Christopher's measurement to Andy's measurement can be calculated as follows

= 2580/3500

= 129 : 175

Hence the ratio of Christopher's measurement to Andy's measurement is 129:175

Answer:

Aren't they equivalent to 5:6?

Step-by-step explanation:

Your situation models to 5x:6x, and no matter what you put as x, it will amount to the ratio of 5:6. It's basically a big fraction, with 5/6 as the simplfication.

Answer:

Step-by-step explanation:

The easiest way to start this is just to multiply the 5 and the 6 by the same thing and see what happens.

Randomly, I will choose 7 because I think today is the 7th.

5*7

====

6*7

35

===

42

I know this is going to seem ridiculous but I'm not going to divide 35/42 by 7.

35 divide by 7 = 5

42 divide by 7 = 6

Just what you started with.

Now a little less obvious, suppose we multiply top and bottom of the ratio by a. a can be anything like (say) the 5th root of 3233

5* a

====

6 * a

Divide the top and bottom by a.

5a divided by a = 5

=======

6a divided by a = 6

So what's the answer? If you've read through this, you'll know that nothing changes.

Step-by-step explanation:

Welcome to the other MHN solving classes.

Let's see what to do ......

_________________________________

Step (1)

EC bisects BED ;

Thus : BEC = CED

_________________________________

Step (2)

Question told us that CED = 4 x + 1

Thus : BEC = CED = 4 x + 1

_________________________________

Step (3)

AD is a straight line which means its angle size is equal to 180° degrees.

So :

AEB + BEC + CED = 180

( 11x - 12 ) + ( 4x + 1 ) + ( 4x + 1 ) = 180

11x + 4x + 4x - 12 + 1 + 1 = 180

19x - 10 = 180

Plus sides 10

19x - 10 + 10 = 180 + 10

19x = 190

Divided sides by 19

[tex] \frac{19}{19}x = \frac{190}{19} \\ [/tex]

[tex]x = 10[/tex]

So : x = 10°

_________________________________

Step (4)

AEB = 11x - 12

AEB = 11(10) - 12

AEB = 110 - 12

AEB = 98°

******************************************************

BEC = CED = 4x + 1

BEC = CED = 4(10) + 1

BEC = CED = 41°

_________________________________

Step (5)

AEC = AEB + BEC

AEC = 98° + 41°

AEC = 139°

Step-by-step explanation:

Consider the formula: [tex]I=PR[/tex]

Here, [tex]I[/tex] represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms).

Resistance = 15 ohms

Current = 4 amps

To find electrical power drawn by a device, put [tex]R=15\,,\,I=4[/tex]

So,
