Answer:
The triangle is a right triangle
Step-by-step explanation:
For the triangle to be right, Pythagoras’ theorem must be obeyed
According to the theorem, the square of the longest side (the hypotenuse) equals the sum of the squares of the two other sides
Now, from the given side lengths, the highest value is 10;
squaring this, we have 10^2 = 100
Squaring and adding the other values, we have
6^2 + 8^2 = 36 + 64 = 100
This mean the values are equal and the Pythagoras’ theorem is obeyed
Hence, we can conclude that the triangle with the given side lengths is a right triangle
Plz help! Sam had an appointment 90 miles away from home at 2pm. He drove there at 60 mph, and was 15 minutes late. What time did Sam start driving at?
Example: 1:50
Answer:
12:45 pm
Step-by-step explanation:
First we find out the amount of time it takes to drive 90 miles at 60 mph.
speed = distance/time
time * speed = distance
time = distance/speed
time = 90 miles / 60 mph
time = 1.5 hour = 90 minutes
It takes 1.5 hour, or 90 minutes, to drive 90 miles at a speed of 60 mph.
To get there at 2:00 pm, he should have left at 12:30 pm.
He got there 15 minutes late, so he must have left 15 minutes late.
He left at 12:45 pm.
Answer: 12:45 pm
A triangle has sides with lengths of 10 millimeters, 17 millimeters, and 18 millimeters. Is it a right triangle?
Answer:
no, it is not
if it were a right triangle, 10² + 17² = 18²
but this is not the case
Step-by-step explanation:
we would use Pythagoras theorem to determine if it is a right angle
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
10² + 17² =
100 + 289 = 389
square root of 389 is 19.72 and not 18. thus, it is not a right triangle
A total of 40 parents volunteered to bring a cake for the Holiday fair.Of the 40 volunteers that brought cake,10 of them brought two cakes. Out of all the cakes at the holiday Fair , 30% were chocolate. How many cakes were chocolate?
Answer:
15!
Step-by-step explanation:
so 40 people volentered to bring cakes, but 10 brought 2. So (30*1)+(10*2)=50 cakes. So, 30 percent of 50 cakes would be 15. To double check, times 50 by 100 and then 30 percent would become 30 (making super sure the actual answer is 15)

given m||n, find the value of x
Answer:
x= 154°
I hope it's helps you
Answer:
x=154
Step-by-step explanation:
The figures provides us with a variable and the number 154.
In this situation, the value of x and the given angle are corresponding angles.
The theorem of corresponding angles states that if a transversal is cut by two parallel lines the corresponding angles are CONGRUENT.
When an angle is congruent, they are equal to each other.
So in this case, x=154, x≅154.

In the first half of the basketball season, Jean made 15 free throws out of the 25 free throws she attempted, for a free-throw shooting percentage of 60%. How many consecutive free-throw shots would Jean have to make to raise her free-throw shooting percentage to 80%?
Answer:
She has to make 25 consecutive free throws
Step-by-step explanation:
Let the number of consecutive throws be x
So, that would mean the number of free throws would total 25 + x
while the number of free throws made would be 15 + x
So for us to have an 80% raise ;
That would mean;
(15 + x)/(25 + x) * 100 = 80
100(15 + x) = 80(25 + x)
1500 + 100x = 2000 + 80x
2000-1500 = 100x-80x
20x = 500
x = 500/20
x = 25
Answer:
She has to make 25 consecutive free throws
Step-by-step explanation:
Let the number of consecutive throws be x
So, that would mean the number of free throws would total 25 + x
while the number of free throws made would be 15 + x
So for us to have an 80% raise ;
That would mean;
(15 + x)/(25 + x) * 100 = 80
100(15 + x) = 80(25 + x)
1500 + 100x = 2000 + 80x
2000-1500 = 100x-80x
20x = 500
x = 500/20
x = 25

А. y - 110 = 70(x - 1)
B. y - 70 = 110(x - 1)
C. y - 670 = 70(x - 1)
D. y - 9 = 70(x - 670)
Answer:
А. y - 110 = 70 (x - 1)
Step-by-step explanation:
А. y - 110 = 70 (x - 1)
A student evaluated -4+x for x = -9 1/2and got an answer of 5 1/2? What might th student have done wrong.
Answer:
Step-by-step explanation:
Expression evaluated by the student is,
(-4 + x)
For x = [tex]-9\frac{1}{2}[/tex]
Value of the expression will be,
(-4 + x) = [tex]-4+(-9\frac{1}{2})[/tex]
= [tex]-4-9-\frac{1}{2}[/tex]
= [tex]-13-\frac{1}{2}[/tex]
= [tex]-13\frac{1}{2}[/tex]
While student evaluated the value of the expression as [tex]-5\frac{1}{2}[/tex].
Mistake done by the student may be in the first step [tex][-4+(-9\frac{1}{2})][/tex].
He might have subtracted [tex](-9\frac{1}{2})[/tex] from (-4).

Answer:
x = 15Step-by-step explanation:
Since the quadrilateral is inscribed into circle, its opposite angles are supplementary:
m∠H + m∠K = 180°Substitute the values and solve for x:
5x - 22 + 8x + 7 = 18013x - 15 = 18013x = 195x = 195/13x = 15Answer:
Solution ::According to the property of Cyclic Quadrilateral
5x - 22 + 8x + 7 = 180
(5x + 8x) - (22 - 7) = 180
13x - 15 = 180
13x = 180 + 15
13x = 195
x = 195/13
x = 15

In physics class, Carrie learns that a force, F, is equal to the mass of an object, m, times its acceleration, a. She writes the equation F=ma.
Using this formula, what is the acceleration of an object with F=7.92 newtons and m=3.6 kilograms? Express your answer to the nearest tenth.
Note: The unit for Force (the Newton) is measured in .
Answer:
2.2
Step-by-step explanation:
if force equals mass times acceleration then you divide 7.92(the force) by 3.6(the mass) to find out what would be multiplied by 3.6 to get 7.92.
Sorry if I'm wrong.
The acceleration of an object with F=7.92 newtons and m=3.6 kilograms is 2.2 m / s²
What is force:Force is a pull or push upon an object that causes motion .
Mathematically, force is express as follows:
F = ma
where
m = mass
a = acceleration
Force is measured in Newton.
Let's find the acceleration of an object with F =7.92 newtons and m = 3.6 kilograms.
7.92 = 3.6a
divide both sides by 3.6
a = 7.92 / 3.6
a = 2.2 m / s²

Answer:
$28.05
Step-by-step explanation:
If you want to find how much the photo album is after the markup, you first have to find 10% of the original price. 10% of $25.50 is $2.55, so you add $2.55 and $25.50 to find the price after the markup.

What is the height of a cone that has a volume of 90 mand has a radius of 3.5 m?
Answer:
Step-by-step explanation:
Calculate the volume of a cone by its base and height with the equation volume = 1/3 * base * height. You can calculate the height of a cone from its volume by reversing this equation. Triple the volume amount. For this example, the volume is 100.

What is the median. I have 3 more questions that have to deal with the median.
Answer:
47.5Step-by-step explanation:
Median - The middle number in a list of numbers starting from least to greatest.
Knowing this, we can start.
The first step is to rewrite all the numbers from least to greatest
15, 19, 28, 32, 43, 52, 66, 72, 72, 81
Now cross off a number from the least and greatest until there is 1 or 2 numbers left
19, 28, 32, 43, 52, 66, 72, 72
28, 32, 43, 52, 66, 72
32, 43, 52, 66
43, 52
If you are left we 1 number, that is your answer. If you are left with 2 numbers, there is an extra step
In the case that you have 2 numbers, you need to add them together, and divide by 2
43 + 52 = 95
95 ÷ 2 = 47.5
Thus 47.5 is our answer
