Answer:
Mark's shadow would be 3 feet.
Step-by-step explanation:
If a building is 50 feet tall and casts a 25 foot shadow, then the shadow of an object is 1/2 the length of the actual object.
This can be supported by the division problem:
50 ÷ 2 = 25
If Mark is 6 feet tall, then we need to divide 6 by 2 in order to find the length of the shadow.
6 ÷ 2 = 3
Therefore, Mark's shadow would be 3 feet.
Hope this helps! :D

The graph shows the amount of money paid when purchasing bags of peanuts at the zoo:
I REALLY NEED HELP!!!
A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 13. Four points are shown on the graph on ordered pairs 0, 0 and 1, 4 and 2, 8 and 3, 12. These points are joined by a line. The label on the x-axis is Bags of peanuts. The title on the y-axis is Total cost in dollars.
What does the point (0, 0) on the graph represent? (4 points)
a
The cost of one bag of peanuts
b
The cost of zero bags of peanuts
c
The cost of two bags of peanuts
d
The cost of three bags of peanuts
Answer:
B, the cost of 0 bags
Step-by-step explanation:
Answer:
b) The cost of zero bags of peanuts
Explanation:
Because it is at (0,0), that means it's at $0 and 0 bags of peanuts based on the labels for the x and y axis.
A quantity with an initial value of 120 decays exponentially at a rate of 9.5% every 7

Answer:
39.46
Step-by-step explanation:
Two systems of equations are shown below:
System A
System B
3x + 2y = 3
−x − 14y = 1
−2x − 8y = −1
−2x − 8y = −1
Which of the following statements is correct about the two systems of equations? (1 point)
The value of x for System B will be one−third of the value of x for System A because the coefficient of x in the first equation of System B is one third times the coefficient of x in the first equation of System A.
The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding −4 to the first equation of System A and the second equations are identical.
They will have the same solution because they represent the same lines when plotted on the coordinate axes.
They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.
Answer:
The two linear equations represented in system A as :
3 x + 2 y =3 -------(1)
- 2 x - 8 y = -1 ------(2)
(1) × 2 + (2) × 3 gives
⇒ 6 x + 4 y - 6 x - 24 y = 6 -3
⇒ - 20 y = 3
⇒ y =
Putting the value of y in equation (1), we get
Two linear equation represented in system B is:
3. -x - 14 y =1
4. - 2 x - 8 y = -1
-2 ×Equation (3) + Equation (4)=
2 x +28 y- 2 x - 8 y= -2 -1
⇒ 20 y = -3
⇒y =
Putting the value of y in equation (3),we get
As Two system , that is system (A) and System (B) has same solution.
By looking at all the options , i found that Option (D) is correct. The two system will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.

Choose all the equations that are true if y = 6.
52.37 – 46.37 = y
2 / 3 y = 4 1/2
8y = 48
3.2 + y = 9
y = 4 = 24
Answer:
The first and third.
Step-by-step explanation:
For the first one, you just subtract 52.37 and 46.37 and the answer is 6, so that makes the equation 6=y, which is right. The second one equals 6.75, so that's not what we need. For the third one, you divide by 8 on both sides to isolate y, and that results in y=6, which is right. For the fourth one you subtract by 3.2 on both sides to isolate y and that results in 5.8, which isn't what we need. I think for the last one you meant to type y=4+24, in which case that would be y=28, which isn't what we need.

PLS HELP
Answer:
18%
Step-by-step explanation:
9/50 = 0.18 and 0.18 is 18% in percentage form
Answer:
18%
Step-by-step explanation:
FIrst set up a fraction so that later we can convert that into a percentage:
9/50
9 represents the number of tickets sold and the 50 represents the total
We divide numerator by denominator.
9/50 =
0.18
We multiply by 100 to get our percentage and we get 18%

Answer: 1/2 as a fraction
.5 as a decimal
Step-by-step explanation: The probability of them rolling a number would be 3/6 or simplified 1/2 because if there is a 6 sided dice the denominator would be 6 and there are 3 odd numbers on the dice which are 1,3,and 5 so if u have to simplify it would be 1/2 if not 3/6. Also 1/2 as a decimal would be .5
Answer:
Fraction: 1/2, Decimal: 0.5
Step-by-step explanation:
From numbers 1 to 6, 3 of them are odd numbers, 1, 3, and 5
So 3/6 of the numbers are odd numbers, now we have to see if we can simplify 3/6, which u can, 3/6 = 1/2
1/2 is ur fraction, to find ur decimal divide 1 by 2, and u get 0.5
i need help on My homework help me
Answer:
x = 18
Step-by-step explanation:
1/2 x - 7 = 1/3 (x - 12) Remove the brackets on the right
1/2x - 7 = 1/3 x - 12*1/3
1/2x - 7 = 1/3 x - 4 Subtract 1/3 x from both sides
1/2x - 1/3x - 7 = - 4 Combine like terms on the left
1/6x - 7 = - 4 Add 7 to both sides
1/6 x = - 4 + 7 Combine the right side
1/6 x = 3 Multiply both sides by 6
6 * 1/6x = 3*6
x = 18

A field is in the shape of a Rectangle. The width
of the rectangle is x yards. The length of the
rectangle is 3 more than the width. Write an
expression for the perimeter of the field.
Answer:
4x+6
Step-by-step explanation:
The perimeter of the field can be obtained by calculating the distance around the field.
in this case, we know that the shape of the field is a rectangle.
The perimeter of a rectangle can be obtained by using the formula
[tex]2(l+b)[/tex]
The width of the rectangle is given as x yards
The length of the rectangle is given as x +3 yards
Therefore, an expression to determine the perimeter of the rectangle can be given as
[tex]2(x+3+x)\\=2(2x+3)\\=4x+6[/tex]
