How to solve:

By setting up an algebraic equation, we can solve this.

Process:

                                                                95/20 + 12/20x = 250/20

                                                                               12/20x= 155/20

                                                                                         x= 12 11/20

Solution: 12 ; 45

The minimum amount of time taken by the machine will be 12 hours and 55 minutes.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

An exceptional machine is utilized at a building site to dig openings. An opening is dug to a profundity of 4.75 feet when the machine hits the rock. The advancement eases back to 3/5 feet each hour of digging. The profundity of the opening should be no less than 12 ¹/₂ feet before the day's over to remain on time.

Convert the mixed fraction number into a decimal number.

12 ¹/₂ feet = 12.5 feet

Let 'x' be the time. Then the equation is given as,

(3/5)x = 12.5 - 4.75

Simplify the equation, then we have

(3/5)x = 12.5 - 4.75

(3/5)x = 7.75

x = 12.9167

x = 12 + 0.9167 x 60

x = 12 hours and 55 minutes

The base measure of time taken by the machine will be 12 hours and 55 minutes.

Find the scale of the two similar sides with known dimensions:

45/27 = 1 2/3

Figure A is 1 2/3 times larger than B. Now multiply the similar side of B to find x:

x = 18 x 1 2/3

x = 30

Answer: x = 30

Answer: 30

Step-by-step explanation:

(This is a similarity question)

So,

X/18 = 45/27

Then cross multiplication

X= 45×18/ 27

X= 30

Answer:

17, 17, 1 13/21

Answer:

1 13/21

Step-by-step explanation:

First, Multiply the 4 and 3 by 7 to get 28/21. Then Multiply the 2 and 7 by 3 to get 6/21. Add them up and you get  34/21. To convert, divide 34 and 21 to get one with the remainder of 13. The final answer is 1 13/21.

Answer:

y=2x+6

I started with the simplist equation for the first set (0,6) of y=X+6 and then tested it out for the second set (1,8) which didn't work. I then ajusted it so it would work with the second set by doing y=2x+6. Lastly, I tested this equation with all of the points and it worked for them all.

Answer:

-8

Step-by-step explanation:

First, you distribute the right side

-48 = 12(m+4)

-48 = 12(m) + 12(4)

Simplify:

-48 = 12m+48

Solve for m

-96 = 12m

m=-8

Answer:

-8

Step-by-step explanation:

-48/12 = m+4

(-48/12) -4 = m

m = (-4) - 4

m = -8

Answer:

f(x)=208^0.3x

Step-by-step explanation:

Think of this as a graph. You start out with 208 caribou, which is your y intercept, as it is there when the growth is 0.

The generic formula fr an exponential equation is a^x.

A represents your initial value. In this case, its 208

x represents the growth. In this case, it's 0.3%.

Your equation should be f(x)=208^0.3x

Answer:

k=69

Step-by-step explanation:

(plug in 69 instead of k)

69/3 = 23.

23+1=24

The ≥ sign means 21 has to be GREATER or EQUAL to 17.

Is it?

24≥17?

YES!

So, it works out.

Step-by-step explanation:

5/6 times 13 is 10 5/6. No

4 times 13 is 52. Yes

3/4 times 13 is 9 3/4. No

10/10 times 13 is 13. Yes

The expressions greater or equal to 13 are B and D.

An expression in math is a statement having minimum of two numbers, or variables, or both and an operator connecting them.

Given are expressions we need to determine expressions having values equal to or greater than 13,

So,

5/6 and 3/4 are numbers less than 1 if we multiply any number with them it will decrease its value,

So, the expression 4 x 13 and 10/10 x 13 will be the expressions having values equal to or greater than 13.

Hence the expressions greater or equal to 13 are B and D.

Answer:

yes every values are increasing constantly by 2.5

Answer:

Step-by-step explanation:

Note that for each unit increase in x, y increases by 2.5.  The constant of proportionality is therefore 2.5:

y = 2.5x

All of the y-values are a constant multiple of the corresponding x-values, so the relationship is a proportional one.
