make m the subject of the formula g=√m-5/2

Answers

Answer:

answer is m = 5 + 2G^2

Step-by-step explanation:

first we have to cancel out the √ by powering both sides by 2

(G) ^2 =(√ m-5/2)^ 2

the 2 on the right side cancels out the √ which will be

G^2 = m - 5/2

we then cross multiply on both sides which will give us:

2*G^2 = m - 5

then carry 5 to the other side

2G^2 +5 = m - 5+5

therefore m = 5 + 2G ^2

clear steps in the picture

hope that helps

answer is m = 5 + 2G^2

Answers

Step-by-step explanation:

step 1. this is a trapezoid. the area A = (b1 + b2)h/2 where b1 is the bottom base and b2 is the top base (per se), and h is the height. this formula is the definition of the area of a trapezoid.

step 2. A = (b1 + b2)h/2 = (22 + 9)(5)/2

step 3. A = 31(5)/2 = 155/2 = 77.5in^2.

Answer:

cousin: m-3

uncle: 5m

together: 6m-3

Step-by-step explanation:

if her cousin is 3 years younger, they would be m-3. since their uncle is her age times 5, he would be 5m. add those and you get 5m+m-3. combine the m's (and get 6m), then add the -3 to get 6m-3

Answer:

her younger sister's age: (m - 3)years , her uncles age ( 5m )

sum of their ages : m + m - 3 + 5m = 7m - 3

Answer:

∴ m∠KIJ = 18°  and   m∠HIJ = 50°

Thus, option a is correct.

Step-by-step explanation:

From the figure, it is clear that:

m∠KIH = m∠HIJ + m∠KIJ

Given

m∠KIH = 68°m∠KIJ = (2x + 6)°m∠HIJ = (9x - 4)°

now substituting m∠KIH = 68°, m∠KIJ = (2x + 6)° and m∠HIJ = (9x - 4)° in the equation

m∠KIH = m∠HIJ + m∠KIJ

68° = (2x + 6)° + (9x - 4)°

switch sides

[tex]\left(2x+6\right)+\left(9x-4\right)=68[/tex]

Group like terms

[tex]2x+9x+6-4=68[/tex]

[tex]11x+2=68[/tex]

Subtract 2 from both sides

[tex]11x+2-2=68-2[/tex]

Simplify

[tex]11x=66[/tex]

Divide both sides by 11

[tex]\frac{11x}{11}=\frac{66}{11}[/tex]

Simplify

[tex]x=6[/tex]

Hence, the value of x = 6

Therefore,

m∠KIJ = (2x + 6)° = 2(6) + 6 = 12 + 6 = 18°

m∠HIJ = (9x - 4)° = 9(6) - 4 = 54 - 4 = 50°

∴ m∠KIJ = 18°  and   m∠HIJ = 50°

Thus, option a is correct.

A warren of rabbits has a population of 25. The population is increasing at a rate of 20% per year. How can you write an exponential growth function to find the monthly growth rate?

A. y = 25(1.2)^t
B. y = 25(1.1)^12t
C. y = 25(1.0167)^t
D. y = 25(1.01531)^12t

Answers

Answer:

b

Step-by-step explanation:

The exponential growth function is "[tex]y = 25(1.0167)^t[/tex]". A complete solution is below.

Given:

Population,

25

Increasing rate,

r = 20%

Now,

The value after 1 year will be:

= [tex]25+(\frac{20}{100} )25[/tex]

= [tex]25+\frac{1}{5}\times 25[/tex]

= [tex]25+5[/tex]

= [tex]30[/tex]

Now

→ [tex]25(1+\frac{R}{100} )^{12} =30[/tex]

→                   [tex]R = 1.67[/tex]

hence,

The exponential growth rate to find the monthly growth rate will be:

→ [tex]y = 25(1.0167)^t[/tex]

Thus the above answer i.e., option C is the correct alternative.

Which is the quotient if 3/5 and 1/10?

Answers

Answer:

6

Step-by-step explanation:

We have two fractions and are asked to find the answer if they both are divided.

3/5 and 1/10.

When we divide fractions, we need to follow KCF

KEEP - Keep the fractions

CHANGE - Change the division sign to a multiplication sign

FLIP - Flip the second fraction

Follow :

KEEP :

3/5 / 1/10

CHANGE :

3/5 * 1/10

FLIP :

3/5 * 10/1

Now we need to multiply, which is simple because it's multiplying across :

[tex]\frac{3*10}{5*1}[/tex]

30/5

Simplify by dividing the numerator and denominator by 5 :

[tex]\frac{30/5}{5/5} = \frac{6}{1}[/tex]

Divide the numerator by denominator :

[tex]\frac{6}{1} = 6[/tex]

Answers

Answer:

x=-5

Step-by-step explanation:

First, you have to cross multiply.

2*2x+3     1*3x+1

4x+6=3x+1

Then, you subtract 3x from both sides.

4x+6=3x+1

-3x     -3x

x+6=1

Next, you subtract 6 from both sides.

x+6=1

    -6  -6

x=-5

Answer:

x = -5 (process below)

Step-by-step explanation:

1) To solve this easily, you can cross multiply. Multiply the numerator of the first fraction with the denominator of the second fraction, and multiply the denominator of the first fraction with the numerator of the second fraction:

[tex]\frac{2}{3x+1} = \frac{1}{2x+3} \\2(2x +3) = 1(3x + 1)\\4x + 6 = 3x + 1[/tex]

2) Next, isolate x to find its values. Subtract both sides by 3x.

[tex]4x + 6 = 3x +1\\x + 6 = 1[/tex]

3) Finally, subtract both sides by 6.

[tex]x + 6 = 1 \\x = -5[/tex]
