Step-by-step explanation:

Assuming the reported monthly growth is for the first month, the height will be ...

  22 7/8 + 4 2/3 = (22 +4) +(21/24 +16/24) = 26 +37/24 = 27 13/24

Answer:

c.

Step-by-step explanation:

Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.

We have $34x + $31.5(17 - x) = $558.

$34x + $31.5(17 - x) = $558

$34x + $535.5 - $31.5x = $558

$2.5x = $22.5

x = 9

Hence the answer is c.

Answer:

x₁ = -4

x₂ = 0.5

Step-by-step explanation:

x² + 3.5x - 2 = 0                 * 2

2x² + 7x - 4 = 0 ​

(2x + 8)(2x -1)/2 = 0

2(x + 4)(2x - 1)/2 = 0

(x + 4)(2x - 1) = 0

x + 4 = 0

x₁ = -4

2x - 1 = 0

2x = 1

x₂ = 1/2

x₂ = 0.5

Answer:

Step-by-step explanation:

Answer:

Points N and K are on a plane A and plane S ( True )

Points P and M are on a plane B and plane S

Point P is the intersection of line n and line g ( True )

Points M, P, and Q are noncollinear ( True )

Line d intersects plane A at point N.

Step-by-step explanation:

Just took the test and got it right :)

The true are 1, 3, 4 and false are 2, 5.

To choose the statement are true or false.

A surface in which if any two points are chosen a straight line joining them lies completely in that surface. A plane is a flat, two-dimensional surface that prolongs infinitely far.

Given that:

1. Points N and K are on plane A and plane S.

From  that points N and K are on the plane A and on the plane S. Thus, this option is true.

2. Points P and M are on plane B and plane S.

From points P and M are on the plane B, but point M doesn't lie on the plane S. So, this option is false.

3. Point P is the intersection of line n and line g.

Point P lies on the line n as well as on the line g, therefore it is the point of intersection of these two lines. This option is true.

4. Points M, P, and Q are noncollinear.

It is true, because points M, P and Q do not lie on the same line at one time, that means they are noncollinear.

5. Line d intersects plane A at point N.

From the line d intersects plane S at point L, not at point N, then this option is false.

Answer:

(0,2) (3,1)

Step-by-step explanation:

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The correct option is A and D.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

If we want to know whether a point is a solution to the equation or not, substitute it in the line and check whether both sides of the equation are equal or not.

A) 0,2

x + 3y = 6

0 + 3(2) = 6

6 = 3

B) 0,6

x + 3y = 6

0 + 3(6) ≠ 6

18 ≠ 6

C) 2,6

x + 3y = 6

2 + 3(6) ≠ 6

2 + 18 ≠ 6

D) 3,1

x + 3y = 6

3 + 3(1) = 6

3 + 3 = 6

6 = 6

E) 4,1

x + 3y = 6

4 + 3(1) ≠ 6

4 + 3 ≠ 6

F) 6, 2

x + 3y = 6

6 + 3(2) ≠ 6

6 + 6 ≠ 6

Answer:

-25.17 miles per gallon.

-It costs $49.02 to fill your tank.

Step-by-step explanation:

-To find the miles per gallon, you can use a rule of three:

17.2 gallons →  433 miles

    1 gallon   →        x

x=(1*433)/17.2= 25.17

If your gas tank holds 17.2 gallons, you car can drive 25.17 miles per gallon.

-To find the cost to fill your tank, you have to multiply the price per gallon for the amount of gallons that the tank can hold:

$2.85*17.2=$49.02

It costs $49.02 to fill your tank.

Answer:

40 blueberry jelly beans

Step-by-step explanation:

Let us represent blue berry beans = b

Cherry jelly beans = c

Camilla has twice as many blueberry jelly beans as cherry jelly beans.

Hence,

b = 2c .........Equation 1

After eating 10 pieces of each kind, she now has three times as many blueberry jelly beans as cherry jelly beans.

hence,

b - 10 = 3(c - 10)

b - 10 = 3c - 30

Collect like terms.

- 10 + 30 = 3c - b

20 = 3c - b .........Equation 2

Subtitute 2c for b in Equation 2

20 = 3c - 2c

20 = c

Hence, she had 20 cherry jelly beans.

In the question, we are asked to find how many blueberry jelly beans she had.

Hence,

b = 2c .........Equation 1

Substituting 20 for c in Equation 1

b = 2 × 20

b = 40

Therefore, she originally had 40 blueberry jelly beans

Step-by-step explanation:

Point T is between Points S and U, where all 3 points are collinear.

Therefore ST + TU must be equal to SU.

(2x + 6) + 4 = 4x

2x + 10 = 4x

2x = 10

x = 5.

Hence, length of ST = 2(5) + 6 = 16.

The length of ST will be 16 units.

A line segment is basically a line with two end points.

two or more than two co-linear points is needed to form a line segment.

In the given question

Line segment is SU

Point T is in between point S and point U here all the points are co-linear

SU = ST + TU

4x = (2x + 6) + 4

4x = 2x + 10

2x = 10

x = 5

∴ The length of  ST = 2x + 6 = (2×5) + 6 = 16 units

We would need to undo the equation and preform inverse operations to get 'x' on one side. First, we need to get rid of 28 by adding 28 to each side. This would leave us with 7x on one side. Then, we wound divide each side by 7. This would leave us with 'x = 8'. If we plugged in the value, then it would satisfy the equation.

Answer: 3⁴

Explanation: Exponential form contains a base and an exponent.

The base is the number that is multiplied.

So in this case, 3 is the base.

Next we write the exponent which is the

number of times that the base is multiplied.

Since 3 is multiplied four times, the exponent is 4.

So in exponential form, 3 · 3 · 3 · 3 can be written as 3⁴.

Distance = 15 1/2 miles

Time = 1/3 hour

Distance =?

Time = 1 hour

Distance : time

15 1/2 miles : 1/3 hour = ? miles : 1 hour

31/2 miles ÷ 1/3 bout = x miles / 1 hour

31/2 × 3/1 = x / 1

Step-by-step explanation:

x=5

Answer:

One solution, x=5.

Step-by-step explanation:

4x-8=12

To find the solution we have to find the value of x.

to find the value of x, we have to add 8 to BOTH sides.

4x-8=12   (Why add 8? because we have to do the opposite of the sign!)

   +8  +8

4x=20

Now to find X we have to ISOLATE IT.

So we take out 4, How? We do the opposite to both sides.

4/4 Cancels out

20/4 = 5

So now we know X=5

Insert in the main problem to check.

4(5)-8=12

20-8=12
