A triangle has sides with lengths of 5 millimeters, 8 millimeters, and 10 millimeters. Is it a right triangle?
Answer:
It is not.
Step-by-step explanation:
Using the Pythagorean Theorem, a squared + b squared = c squared, we get 25 + 64 = 100, and this is not true.

Step-by-step explanation:
Ms. Carey grades 4 tests during her lunch. She grades 1/3 of the remainder after school. If she syill5has 16 test to grade after school, how many test are there?
Answer: 24 tests
Step-by-step explanation:
Ms. Carey graded 1/3 of the tests and still had 16 tests to go.
This means that the 16 tests represent the remaining proportion of the total number of tests:
= 1 - 1/3
= 2/3
2/3 of the total is equal to 16 tests. Assuming the total is x, the expression would be:
2/3x = 16
x = 16 ÷ 2/3
x = 16 * 3/2
x = 24 tests

Answer:
slope = [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 0 ) and (x₂, y₂ ) = (2, 4) ← 2 points on the line
m = [tex]\frac{4-0}{2-(-3)}[/tex] = [tex]\frac{4}{5}[/tex]

The radius of a circle is 1 yard. What is the circle's circumference?
r=1 yd
Answer:
6.3 yards
Step-by-step explanation:
mathematically, to get the circumference of the circle, we will have to use the formula for the circumference of a circle
we have this as;
C = 2 * pi * r
r is 1 yard
c = 2 * pi * 1 = 2pi yards = 6.3 yards

y – 1.02 = 4.7
solve for y
Answer:
y=5.72
Step-by-step explanation:
Let's solve your equation step-by-step.
y−1.02=4.7
Step 1: Add 1.02 to both sides.
y−1.02+1.02=4.7+1.02
y=5.72
Answer: y=5.72
Step-by-step explanation:
4.7 plus 1.02 equals 5.72
5.72 minus 1.02 equals 4.7
You recently spent $22 to purchase a notebook, a box of pencils, and a package of pens. The box of pencils costs $2 less than the notebook. The package of pens costs 3 times as much as the box of pencils. Write and solve an algebraic equation to find the cost of each item you purchased.
Answer:
The answer is down below:
Step-by-step explanation:
Notebook: 22-x
Pens: (22 - x - 2) x 3.
Pencils: 22 - x - 2.
We use x for notebooks because it is the only item that doesn't have an "equation" for us to solve so we use "x" instead. hope this helped you out.

=> B) The amount of popcorn that fits in a particular container.
Explanation:=> The amount of space that a substance or object occupies, or that is enclosed within a container is known as volume. The first & third option measures the surface area while the fourth option measures the distance covered. Thus, the second option (b) is the correct answer.
[tex] \infty \infty \infty [/tex]
Answer:
B. The amount of popcorn that fits in a particular container.
Step-by-step explanation:
Volume is the amount of space that is inside a three dimensional shape. In other words we need a box/container that has empty space in it. That space is the volume. Knowing this we can start eliminating answer. First we can eliminate answer D. This answer makes no sense when comparing it to what is needed for volume. Answer D has to do with distance. Then we can eliminate answer C. This answer does can not work because it says "square inches". This means that it is either the area of a two dimensional shape or it could be the outside of a three dimensional shape. Answer A. is like answer C. It is the outside of a shape and not the inside. That leaves us with answer B. Answer B says "that fits in a particular container". From this we can see that they are fitting something inside a container. These are the key words for volume.
Anna's car requires 5 1/2 gallons of gasoline to make 4 round trips to work and back. If her car can travel 24 miles per gallon of gasoline, how far, in miles is one round trip to work and back?
Answer:
33 miles
Step-by-step explanation:
5.5÷4= 1.375 gal per round
1.375×24= 33 miles

(the points O K and P are collinear )
(the points O B and A are collinear)
(KB) and (PA) are parallel
OK=X,OP=Y
KB=5
KP=6
and PA=8
CALCULATE THE LENGTH OP
Answer:
see in the picture, we have: y = 6 + x
=> x = y - 6
because KB//PA, using Thales Theorem, we have:
[tex] \frac{ok}{op} = \frac{kb}{pa} \\ \\ = > \frac{x}{y} = \frac{5}{8} \\ \\ < = > \frac{y - 6}{y} = \frac{5}{8} \\ \\ < = > 5y = 8(y - 6) \\ \\ < = > 5y = 8y - 48\\ \\ < = > 3y = 48 \\ \\ = > y = 16[/tex]
because OP = y => OP = 16

Catherine Lewiston is currently earning an annual salary of $36,080 at
Zimmerman Heating Company.
She has been offered a job at a steel company at an annual salary of $47,120.
How much more would she earn per week at the steel company than at Zimmerman Heating?
Answer:
$212.31
Step-by-step explanation:
divide $36,080 by 52 weeks in a year. you get $693.84 weekly.
divide $47,120 by 52 weeks in a year. you get $906.15 weekly.
then subtract 906.15 from 693.84 and you get 212.31
What is a linear and non-linear trend?
9514 1404 393
Explanation:
Linear trend
A linear trend is one that is best approximated by a straight line. Sometimes we use a straight-line approximation, even when it may not be a very good fit, because we are only interested in the sign of the slope, or its approximate magnitude. The parameters of a linear trend are about the easiest to calculate (though it doesn't matter much if an appropriate tool is used).
__
Non-linear trend
A non-linear trend is one that is best approximated by a curve other than a straight line. Trig functions (sine, cosine), exponential functions, quadratic functions are often used. Non-linear trends are not restricted to these kinds of functions.
A car is traveling down a road at a constant speed of 50 miles per hour. Write an equation that represents the distance traveled by the car, d, for an amount of time, t
Answer:
distance divided by rate = time aka D/R=T
Step-by-step explanation:
this is what i learned at least hope it helps
The equation that represents the distance traveled by the car is equal to d = 50 x t.
Speed calculation
To calculate the speed of an object, it is necessary to relate the distance traveled and the time required to travel that distance, so that:
[tex]V = \frac{d}t}[/tex]
Thus, as we are given the value of a velocity and if we are asked for the expression that represents the distance traveled depending on the time, we have:
[tex]50 miles/hour = \frac{d}{t}[/tex]
[tex]d = 50 \times t[/tex]
So, the equation that represents the distance traveled by the car is equal to d = 50 x t.
