A ruler is 12 inches long. What is the length of this ruler in centimeters? Round to the nearest hundredth.
Answer:
30.48 cm
Step-by-step explanation:
There are ~ 2.54 centimeters in 1 inch. If the ruler is 12 inches long, multiply 2.54 cm by 12:
12 inches x 2.54 cm = 30.48 cm.
Jack is 1.78 m tall.
Amy is 5 cm taller than Jack.
How tall is Amy?
Answer:
1.83
Step-by-step explanation:
1.78 + 5 cm
because it says she is taller so you add both
Height of Amy who is 5 cm taller than Jack is 1.83 meters.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Jack is 1.78 m tall and Amy is 5 cm taller than Jack.
Therefore, The sum of the height of Jack and 5 cm more is the height of
Amy.
Therefore,
178 cm + 5 cm = 183 cm is the height of Amy. (1m = 100 cm)
So, 183 cm is equal to 1,83 meters.

Which one of the triangles below is NOT a right triangle
Answer:
Second one.
Step-by-step explanation:
A right triangle is a triangle with one right angle. A right angle can be shown with a box, we see that in 1, 3, and 4, there is a box, so that means 2 is not a right angle. We can also do out the math for number 2, so 67+67 = 134, and 180 - 134 is not 90.

Which of the following is equivalent to 10 – 4x < 50?
Answer x = -10
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
10-4*x-(50)=0
STEP1:Pulling out like terms
1.1 Pull out like factors :
-40 - 4x = -4 • (x + 10)
Equation at the end of step1:
STEP2:
Equations which are never true:
2.1 Solve : -4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : x+10 = 0
Subtract 10 from both sides of the equation :
x = -10

What is the y intercept of the line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3)
The line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
The given equation of a line is y=-3/4x+5 and the coordinate point is (-3, -3)
Here, slope of a line is -3/4.
The slope of a line perpendicular to given line is m1=-1/m2
Now, the slope of a line is -4/3
Substitute m= -4/3 and (x, y) =(-3, -3) in y=mx+c, we get
-3=-4/3 (-3)+c
c=-7
Substitute m= -4/3 and c=-7 in y=mx+c, we get
y=-4/3x-7
Therefore, the line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.

Under her cell phone plan, Peyton pays a flat cost of $48 per month and $3 per gigabyte. She wants to keep her bill at $60.60 per month. Write and solve an equation which can be used to determine gg, the number of gigabytes of data Peyton can use while staying within her budget.
Answer: 4.20 gigabyte
Step-by-step explanation:
Based on the information given in the question, the equation that can be used to determine the the number of gigabytes of data Peyton can use while staying within her budget will be:
48 + 3g = 60.60
3g = 60.60 - 48
3g = 12.60
g = 12.60/3
= 4.20
The number of gigabytes of data is 4.20g
Answer:
Equation: 3g+48=60.6
Answer: g=4.2

This table represents the relationship between m, the amount of
money an employee has in the morning, and p, the amount of
money an employee has later in the day after they receive their
paycheck.
Which equation represents the relationship in the table?
a) p=m-160.25
b) p=160.25-m
c)p=m+160.25
d)p=200.25m+160.25
Answer:
bB
Step-by-step explanation:
The correct equation which represents the relationship in the table is,
⇒ p = m + 160.25
Where, m, the amount of money an employee has in the morning, and p, the amount of money an employee has later in the day after they receive their paycheck.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
This table represents the relationship between m, the amount of money an employee has in the morning, and p, the amount of money an employee has later in the day after they receive their paycheck.
Hence, By all options, we can check by substitute the given values.
So, By option 3;
The equation is,
⇒ p = m + 160.25
Substitute m = 200.25,
⇒ p = 200.25 + 160.25
⇒ p = 360.50
Thus, The correct equation which represents the relationship in the table is,
⇒ p = m + 160.25

FERRIS WHEEL The Ferris wheel at an amusement park has a radius of 10.2 meters. A rider, who is sitting level with the center of the Ferris wheel, is 13.1 meters above the ground. At what height above the ground is the rider when the wheel rotates another 140°? Round to the nearest tenth if necessary.
Answer:
19.7 m
Step-by-step explanation:
Draw a circle to represent the ferris wheel with a 10.2 m radius. Draw a horizontal line through the circle center horizontal to the ground (at 13.1 m). Now draw a line from the center of the circle (ferris wheel) upward at 140 degrees until you reach the edge of the circle. Draw a line down from that point to the horizontal line at This is your right triangle to solve.
Hypotenuse is 10.2 m (radius of circle)
The angle of the triangle the supplementary angle of 140 degrees. 180-140=40 degrees
sin 40 degrees=rise /radius=rise/10.2
sin 40=0.6428=rise/10.2
rise=10.2(0.6428)
rise=6.6 m
13.1+6.6=19.7 m
