This triangle is obtuse.
What is right triangle?Triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.
Let a = 6 ,b = 11 & c = 14 be the sides of a traingle, c being longest of three
If a²+b²=c² it is right angled,
If a²+b²>c² it is acute,
If a²+b²<c² it is abtuse,
Substitue the values of a, b and c,
a²+b²= 6²+11² = 157
c² = 14² = 196
Since a²+b²<c²
Hence, this triangle is obtuse.

Please help me circles.....
Answer:
95
Step-by-step explanation:
The equation is
x×2=285-x
3x=285
x=95
Answer:
x = 75°
Step-by-step explanation:
There are many Circle Geometry Rules. We will be using the following:
The angle at the centre of the circle is twice the angle at the circumference.
x = the angle opposite 285 - x.
This means that 360 - (285 - x) = 2x
360 - 285 + x = 2x
75 + x = 2x
We can simplify this by taking away x from both sides.
75 = x
We can check this by substituting x into the orginal equation.
360 - (285 - x) = 2x
360 - (285 - 75) = 2 * 75
360 - 210 = 2 * 75
150 = 2*75
150 = 150
7th grade math help me pleaseee :)
Answer:
answer of 2a)
He started with $24 and spent $16. Let a represent his account balance after he bought the notebook and pens. Then
24–16=a
His new account balance is $8.
He has $8 in his account and then he deposited b dollars. His account balance is now $28. Then
8+b=28
His deposited $20 in his account.
He has $28 and spent $34. Let c represent his account balance after he bought the book. Then
28–34=c
His new account balance is -$6.
He started with an account balance of -$6 and paid the debt off so his account balance is 0. If d is the amount money he deposited to pay off his debt, then
−6+d=0
He deposited $6.
answer of 2b)
If he spends more than he has in his account, then we are subtracting a bigger number from a smaller number, and the result is negative. ... The opposite of a positive number is a negative number, so it makes sense to represent his account balance with a negative number when he owes money to the bookstore.

Answer:
a) 9/2 = 4.5, bushels per hour
b) (3, 10), (6, 20), (9, 30), (12, 40)
c) Shawn
Step-by-step explanation:
a) The line goes through the grid point (4, 18), so its slope is ...
18/4 = 4.5 . . . . slope = "unit rate"
The units are (y-units)/(x-units) = bushels/hour.
__
b) You have correctly filled in the table.
Time-values are 3, 6, 9, 12.
Fruit values are 10, 20, 30, 40.
The unit rate for Carla is ...
10 bu/(3 h) = 3 1/3 bushels/hour ≈ 3.33 bushels/hour
__
c) Shawn's unit rate of 4.5 bushels per hour is greater than Carla's unit rate of 3.33 bushels per hour. Shawn picked fruit at a faster pace.
Miya flips a coin and rolls a 6-sided number cube labled 1-6 and records tge outcome. About how many times is she likely to flip heads and roll a 3 out of 48 trials
Answer:
4 times
Step-by-step explanation:
Sample space :
6 sided cube = (1, 2, 3, 4, 5, 6)
Coin = (H, T)
Probability = required outcome / Total possible outcomes
Probability of head (H) = P(H) = 1 /2 = 0.5
Probability of 3 = P(3) = 1 /6 = 0.166666
Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333
Hence, expected number of times this is likely to occur in 48 tries :
0.083333 * 48 = 4
Use the picture below to answer questions 13a and 13b.
13a) What is the measure, in degrees, of angle 1? Explain how you determined the measure of angle 1.
13b) What is the measure, in degrees, of angle 2? Explain how you determined the measure of angle 2
Answer:
13a: Measure of angle 1 is 120 degrees
13b: Angle 2 is 60 degrees
Step-by-step explanation:
Angle 1 is alternate exterior (so in a parallel pair they are equal) to the angle on line m given as 120 deg.
Angle 2 is 180 minus 120= 60 Sum of the two angles must equal 180.

Answer:
truck is 100mph
Step-by-step explanation:
Use parentheses to show two ways of grouping the numbers in 12 • 8 • 25. Tell which expression you think would be easier to simplify, and why. Then simplify the expression.
Step-by-step explanation:
First no. is 12
Second no. is 8
Third no. of 25
Way 1 of grouping the numbers,
(12×8)×25
We can use associative law of multiplication as follows :
(a×b)×c = a×(b×c)
(12×8)×25 = (96) × 25
= 2400
Way 2,
12×(8×25) = 12 × 200
= 2400
Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.

Which ordered pair is the solution to the system of equations ?
Answer:
c
Step-by-step explanation:
Given the2 equations
y = x + 4 → (1)
x + y = 2 → (2)
Substitute y = x + 4 into (2)
x+ x + 4 = 2
2x + 4 = 2 ( subtract 4 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Substitute x = - 1 into (1) for corresponding value of y
y = - 1 + 4 = 3
solution is (- 1, 3 ) → c

What is the slope ?????????
Answer:
[tex]m=\frac{8}{5}[/tex]
Step-by-step explanation:
Answer: The slope is -8/5
Step-by-step explanation:
Using the located points (-1,4) and (4,-4) we will find the difference in the y coordinates of the points and divide it by the difference in the x coordinates of the same points.
Difference in y: 4 - (-4) = 8
Differecence in x -1 - 4 = -5
Slope: 8/-5
A biologist recorded a count of 348 bacteria present in a culture after 5 minutes and 1088 bacteria present after 20 minutes. To the nearest whole number, what was the initial population ?
Answer:
The initial bacteria population is 238
Step-by-step explanation:
Let us have the increase as an exponential equation
P(t) = I(1 + r)^t
where P(t) is the count at a particular time
r is the percentage increase
I is the initial population
t is the time
So for 5 minutes, we have
348 = I(1 + r)^5
For 20 minutes
1088 = I(1 + r)^20
Divide the second equation by the first
1088/348 = I(1 + r)^20/I(1 + r)^5
3.13 = (1 + r)^15
Take the ln of both sides
ln 3.13 = 15 ln (1 + r)
ln 3.13/15 = ln (1 + r)
0.0761 = ln (1 + r)
1 + r = e^0.0761
1 + r = 1.079
r = 1.079-1
r = 0.079 which is 7.9%
So per minute. we have an increase of 7.9%
So let’s get I by substituting
From;
348 = I(1 + 0.079)^5
348/1.079^5 = I
I = 237.9 which is 238 to the nearest whole number

What is the measure of H?
PLEASE HELP
Answer:
h = 100
Step-by-step explanation:
plz mark my answer as brainlist plzzzz vote me also
Answer:
100°
Step-by-step explanation:
Ok so it looks overwhelming at first, but you just need to make sections and break it down
You are looking for h°, so you want to make it a triangle
The angles of this triangle would be h°, 40°, and x°
You can find x° by using the 140° on the same line
it is a straight line, so that means its angle is 180°
180° - 140° = 40°
x° = 40 °
so now you know that the angles in the triangle are h°, 40°, and 40°
Every triangle has angles that measure to 180°
180° - 40° - 40° = 100°
h° = 100°
Sodium-24 has a half-life of 15 hours. When will 4 mg of Sodium-24 remain if the original sample contains 64 mg?
Answer:
60 hours
Step-by-step explanation:
We are given;
Initial amount: A_o = 64 mg
Half life; T_½ = 15 hours
Amount left: A = 4 mg
To get the time that 4 mg of Sodium-24 remain, we will use the formula;
A = A_o(½^(t/T_½))
Where t is the time that 4 mg of Sodium-24 remain.
Thus;
4 = 64 × ½^(t/15)
Divide both sides by 64 to get;
4/64 = 2^(t/15)
0.0625 = ½^(t/15)
In 0.0625 = (t/15) In 0.5
-2.7726 = (t/15) × -0.6931
t = (-2.7726 × 15)/-0.6931
t = 60 hours

Rachel earns $67.50 for working 9 hours at the dairy farm. How much does Rachel make per hour? How much would Rachel make if she works 5 hours a day for 6 days?
Answer:
$225
Step-by-step explanation:
Frist, we need to figure out how much Rachel makes per hour. For 9 hours of work, she makes $67.50
67.5 / 9 = 7.5
Rachel makes $7.50 per hour
Now we can add up all the hours she worked.
5 hours a day for 6 days
5 x 6 = 30
She worked 30 hours at a rate of $7.50 per hour
7.5 x 30 = 225
She earned $225
10. The perimeter of a rectangle is 96m. Its length is double its breadth. Find its length and breadth.
11. Observe the following and identify the type of angles in them.
Answer:
breadth=16cm and length=32cm
Let breadth be X
According to question,
lengtg=2X
Now,
Perimeter=2(l+b)
or,96=2(2X+X)
or,96=2(3X)
or,96=6X
or,96/6=X
or,X=16cm.
length =32 cm and breadth =16 cm
Answer:
length = 32 cm, breadth = 16 cm
Step-by-step explanation:
let breadth be b then length is 2b, then
2b + 2(2b) = 96
2b + 4b = 96
6b = 96 ( divide both sides by 6 )
b = 16
Thus
breadth = 16 cm and length = 2 × 16 = 32 cm
