Answer:

x = 1 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

make equal equations first

[tex]\frac{3/4}{1 and 1/8}[/tex]  =  [tex]\frac{1}{x}[/tex]

cross multiply to get: 3/4x = 1 [tex]\frac{1}{8}[/tex]  

divide by 3/4 on both sides: x = 1 [tex]\frac{1}{2}[/tex]

no way i can do math like that

Answer:

3.14d > 50 cm

Step-by-step explanation:

Given that the circumference of a circle is approximately 3.14 times the length of its diameter

If the circumference is C and the length of the diameter is d then

C = 3.14d

If the circumference of a circle is more than 50 cm then

3.14d > 50

The  inequality can be used to find all possible diameter lengths, d,

d > 50/3.14

d > 15.92cm

Answer:

n=m+1

Step-by-step explanation:

7m+2=7n-5

add 5 to each side

7m+7=7n  or 7n=7(m+1)

divide both sides by 7

n=m+1

Answer:

We have that 7m + 2 = 7n - 5

If we want to get n, you can use operations in both sides of the equation to make n the independent variable.

First, from 7m + 2 = 7n - 5, we can sum to both sides 5

7m + 2 + 5 = 7n - 5 + 5

7m + 7 = 7n

Now, we can devide both sides by 7:

(7m+7) /7 = 7n/7

7m/7 + 7/7 = n

m + 1 = n

Answer:

14 points.

Step-by-step explanation:

To solve this problem, let's make an equation.

Let x represent the unknown number, or the amount of points Andre scored.

We know that Noah scored 10 points.

Noah scored twice as many points as Diego, therefore Diego must've scored 5 points, because 5 * 2 = 10.

So, if Diego scored 9 points less than Andre, and we know that Diego scored 5 points, then the equation we are left with is

x - 9 = 5

To solve, just add 9 to both sides.

x - 9 + 9 = 5 + 9

We are left with:

x = 14

So, Andre scored 14 points.

Answer:

Step-by-step explanation:

There is an error in the question. 6x+4y = 48

Multiply first equation by 10:

20x+10y = 50

Divide second equation by 2:

3x+2y = 24

50>24, so 20x+10y > 3x+2y

Answer:

The Answer Is C ) 0

Step-by-step explanation:

Answer:

According to the question z must be equal to 4. So value of a+b=z or a+b=4

Lets try each of the options

A) a+b

1.6+2.3=3.9 which is not equal to 4

So option a is not the asnwer.

B) a+b = 1.6+2.5= 4.1 which is not equal to 4

C) a+b= 1.9+2.1= 4.00 which is equal to 4

D) a+b= 2.1+3.4= 5.5 which is not eqaul to 4

Thus, we have OPTION C AS THE CORRECT ANSWER

Answer:

5400

Step-by-step explanation:

Given data

P= 5000

r= 8%

t= 1 year

The simple interest expression is given as

A= P(1+rt)

Required

The final amount A

substitute

A= 5000(1+0.08*1)

A= 5000*1.08

A= 5400

Hence the final amount 5400

Answer:

6x^3+16x^2 I think that is correct

Step-by-step explanation:

Answer:

The diver will hit the water at 1.5 seconds

Step-by-step explanation:

Given

[tex]h= -16(t-1.5)(t+1)[/tex]

Required (Missing from the question)

When will the diver hit the water?

To do this, we simply solve for t

When the diver hits the water, the height is 0 (at that point)

So, substitute 0 for h in [tex]h= -16(t-1.5)(t+1)[/tex]

[tex]0= -16(t-1.5)(t+1)[/tex]

Divide both sides by -16

[tex]\frac{0}{-16} =\frac{-16(t-1.5)(t+1)}{-16}[/tex]

[tex]\frac{0}{-16} =(t-1.5)(t+1)[/tex]

[tex]0 =(t-1.5)(t+1)[/tex]

[tex](t-1.5)(t+1)=0[/tex]

Split

[tex]t - 1.5 = 0[/tex] or [tex]t + 1 = 0[/tex]

Solve for t

[tex]t = 1.5[/tex] or [tex]t = -1[/tex]

But time (t) can not be negative.

So:

[tex]t = 1.5[/tex]

Hence, the diver will hit the water at 1.5 seconds

Answer:

29% of the drive

Step-by-step explanation:

The plot of the problem is:

Transmitter at origin (0,0)  

City to the north at (0,70)

City to the east at (74,0)

The path from city to city is a line with slope:

m = (-70)/74 = -35/37

and y-intercept at y = 70, so the equation is y = (-35/37)*x + 70.

The transmitter reach the area enclosed by the next circle:

x^2 + y^2 = 53^2

See the picture attached

The intersection is gotten from the picture or solving:

x^2 + [(-35/37)*x + 70]^2 = 53^2

the points approximately are: (24.1, 47.2) and (45.8, 26.7)

From Pythagorean theorem the total distance of the trip is:

d1 = √(70^2 + 74^2) ≈ 101.9 miles

And the distance when the signal is picked up is:

d2 =√ [(45.8 - 24.1)^2 + (47.2 - 26.7)^2] ≈ 29.9 miles

You will pick up a signal from the transmitter in (d2/d1)*100 = 29% of the drive.

Answer:

Option A i.e. 8, 3, -2, -7, ... is correct.

Step-by-step explanation:

Let us check the sequence given in option A

[tex]8, 3, -2, -7, . . .[/tex]

An arithmetic sequence has a constant difference '[tex]d[/tex]' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

determine the differences of all the adjacent terms of Arithmetic sequence

[tex]3-8=-5,\:\quad \:-2-3=-5,\:\quad \:-7-\left(-2\right)=-5[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=-5[/tex]

Therefore, we conclude that the arithmetic sequence 8, 3, -2, -7, ... has a common difference -5.

Hence, option A i.e. 8, 3, -2, -7, ... is correct.

Answer:

8, 3, –2, –7, . . .

Step-by-step explanation:

Answer: 21.

Step-by-step explanation: If you do '90 x 7' you get 630. With this, you will want to divide 630 by 30. So to simplify this, '(90 x 7) ÷ 30 = 21'
