Answer:
26.73 minutes have gone by
Step-by-step explanation:
Use cross multiplicationx 27
---- = ----- since we are trying to find how many minutes out of 99 passed,
99 100 place x for the missing digit
solvex times 100 = 99 times 27
simplifyx100 = 2673 x times 100 is just x100 since we don't know what x is, and 99
times 27 is 2673
figure for xx100 = 2673 to find x, it needs to be alone (x is very introverted :'> ) we can
---- ------- remove 100 by doing the opposite of what 100 is doing to the
100 100 x. Since it is 100 TIMES x, we will remove it by dividing 100 by
100 (which crosses it out) and then 2673 divided by 100. 2673
x = 26.73 divided by 100 gives us 26.73, so x equals 26.73.
the area of a square is equal to the area of a rectangle of length = 8cm breadth = 2cm .
what is the side of the square❓
Answer:
4 cm
Step-by-step explanation:
Area of rectangle = Area of square
= 8 x 2
= 16 cm²
Side length = √Area
= √16
= √4 x √4
= 4 cm

Answer:
umm i think for the coin its 50% maybe? because tails would be 1/2
Step-by-step explanation:
im not sure for the second one though D:
Answers and Explanation:
8. It is a fair coin, meaning it has 2 equal landing possibilities. The probability of the coin landing on Head or Tail is equal, so the answer is 1/2
250 contestants playing, means the coin is flipped 250 times. Multiply the probability of it landing on Tails by the number of contestants.
=> [tex]\frac{1}{2}*250=125[/tex] . Therefore 125 contestants are expected to win.
10. The sample space is made of 1-12, there are 12 numbers. Probability is equal to number of outcomes/ sample space
a. P(x>10) = 2/12 = 1/6
This is because there are 2 numbers greater than 10. They are 11 and 12.
b. P(x<5) = 4/12 = 1/3
There are 4 numbers smaller than 5 (1,2,3,4)
c. P(4,6,9) = P(x=4) + P(x=6) + P(x=9)
=> 1/12 + 1/12 + 1/2 = 1/4
It is 1/12 for all three because there's only one of each number in the sample space. We add because in probability 'OR' means 'ADD'.
Now multiply your probability by the number of times the solid was rolled for your final answer.
=> [tex]1/4*200= 50 times[/tex]
50 times is the final answer

Determine if each set of numbers can be the lengths of the sides of a right triangle:
Solution:
The side lengths can only be classified as a right triangle if it is a Pythagorean triple. To classify the side lengths as a Pythagorean triple, it must satisfy "c² = b² + a²".
Where:
c = Longest side (Hypotenuse)b = Lega = LegChecking (5, 12, 13):
c² = b² + a²13² = 12² + 5²169 = 144 + 25169 - 144 = 2525 = 25 (Yes)Checking (12, 35, 20√3):
(20√3)² = 35² + 12²(20√3)(20√3) = 1225 + 1441200 = 1225 + 144 (No)Checking (5, 10, 5√5):
(5√5)² = 10² + 5²125 = 100 + 25125 = 125 (Yes)Checking (8, 12, 15):
15² = 12² + 8²225 = 144 + 64 (No)Checking (20, 99, 101):
101² = 99² + 20²10201 = 9801 + 40010201 = 10201 (Yes)Find the volume of the triangular prism shown below:
Answer:
18 cm³
Step-by-step explanation:
To find the volume of a triangular prism, find the area of the cross-section (in this case, the triangle) and multiply it by the length.
The area of the triangle is 1/2 × 4 × 3 = 6 cm²
Now, multiply 6 by 3 to get 18 cm³

35 POINTS! Identify JS rounded to the nearest tenth.
please help I will give brainliest fr!
Answer:
JS is about 69.4
Step-by-step explanation:
Notice that the given side length JW = 67 is opposite to the given angle S = 44º. JS is adjacent to angle S, so we use the tangent function to solve for JS:
[tex]\tan 44^{\circ} = \frac{JW}{JS}\\\\\tan 44^{\circ} = \frac{67}{JS}\\\\JS = \frac{67}{\tan 44^{\circ}}\\\\JS = 69.3805[/tex]
Round JS to the nearest tenth, 69.4.
Answer:
JS is approx. 69.4
Step-by-step explanation:
This triangle is close to a 45-45-90 triangle. So you then know the answer should be close to 67 because the other side is the same. This leaves us with JS=64.7 and JS=69.4. Another rule says that the side with the smaller angle is greater. 69.4 is greater.

Total price = sale price x (1 + sales tax %)
total = 13.23 x ( 1 + 0.08)
total = $14.29
Answer:
$14.2884
original price: $13.23
with tax: 100% + 8% = 108%
cost with tax:
108% * $13.23
$14.2884
The measure of one interior angle of a reqular 45-gon
Answer:
4 degrees :)
Step-by-step explanation:
All the interior angles must equal 180 degrees. So, we can do 180/45 which equals 4 degrees. Hope this helps. Btw all exterior angles equal 360 degrees, just in case you need to know that on your next assignment. Peace, man!
please help me on this
Answer:
74°
Step-by-step explanation:
There are a couple of different angle relations that can be used to solve this problem. The measure of an inscribed angle is half the measure of the arc it subtends. The measure of an exterior angle of a triangle is equal to the sum of the remote interior angles. The measure of an exterior angle at the intersection of secants is half the difference of the arcs the secants subtend.
__
Using the secant relation, we find ...
∠Y = 1/2(RS -VX)
2×∠Y +VX = RS
2(28°) +18° = 74° = arc RS
__
Using the relations involving interior and exterior angles of a triangle, we have ...
∠S = 1/2(VX) = 1/2(18°) = 9°
∠RVS = ∠S +∠Y = 9° +28° = 37°
arc RS = 2×∠RVS = 2(37°) = 74°

the local college has a swimming pool that measures 50 m longand 25m wide. If you swam from one corner to the other, how far would you swim
Answer:
55.902m
Step-by-step explanation:
a^2 + b^2 = c^2
the diagonal line through the swimming pool is the hypotenuse that splits the pool into two equal right triangles
25^2 + 50^2 = c^2
625 + 2500 = c^2
3125 = c^2

Answer:
≈ 7.85 cm
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
given A = 225π , then
πr² = 225π ( divide both sides by π )
r² = 225 ( take square root of both sides )
r = [tex]\sqrt{225}[/tex] = 15
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr × [tex]\frac{30}{360}[/tex]
= 2π × 15 × [tex]\frac{1}{12}[/tex]
= 30π × [tex]\frac{1}{12}[/tex]
= [tex]\frac{30\pi }{12}[/tex]
≈ 7.85 cm ( to 2 dec. places )
How many solutions are in the equation
Answer:
no solutions
Step-by-step explanation:
The equation simplifies to 13 = -3, which is not true for any value of x.
How many solutions does the system of equations below have?
3x - 2y = 4
6x - 4y = -11
I think 3 or maybe 2 because if ........
How you solve this by using solving proportions
3/(x + 4) = (x + 2)/5
Multiply both sides by 5 :
5 × 3/(x + 4) = 5 × (x + 2)/5
15/(x + 4) = x + 2
Multiply both sides by x + 4 :
(x + 4) × 15/(x + 4) = (x + 4) × (x + 2)
Provided that x + 4 ≠ 0, we can cancel the factors of x + 4 on the left side:
15 = (x + 4) (x + 2)
Expand the product on the right side:
15 = x² + 6x + 8
Move everything to one side:
0 = x² + 6x - 7
We can factorize easily in this case
0 = (x + 7) (x - 1)
Then
x + 7 = 0 or x - 1 = 0
⇒ x = -7 or x = 1
2.The table below shows the relationship between the number of tickets sold for a concert and a theater's net profit, in dollars. Determine the rate of change and what the rate of change

The rate of change is 1/10. This means every 1 ticket sold produces a net profit of $10.00.
The rate of change can not be determined from the table above.
The rate of change is 10. This means every 1 ticket sold produces a net profit of $10.00
The rate of change is 10. This means every 10 tickets sold produces a net profit of $1.00.
The true statement about the rate of change of the table is (c) The rate of change is 10. This means every 1 ticket sold produces a net profit of $10.00
How to determine the rate of changeFrom the table, we have the following ordered pairs
(x,y) = (150,-500) and (200,0)
The rate (r) is then calculated as:
[tex]r = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, the equation becomes
[tex]r = \frac{0 + 500}{200 - 150}[/tex]
Evaluate the difference and the sum
[tex]r = \frac{500}{50}[/tex]
Evaluate the quotient
[tex]r = 10[/tex]
The value of the rate represents that for every 1 ticket sold, there is a net profit of $10
