A) the angles
Step-by-step explanation:Similar triangles are triangles that have the same shape but different sizes.
Angles
Since similar triangles have the same shape, all of the angles must be congruent. If any of the angles are different sizes, then the shape of the entire triangle would change.
Sides
The sides of a similar triangle are not necessarily congruent. However, because all of the angles are congruent, the sides are proportionate. This means that if you are given the sides and angles of one triangle, you can find the sides and angles of any similar triangle.
What’s the area formula, of 48m
Answer:
The area formula of a circle is [tex]A=\pi* r^2[/tex] where r is the radius and in this case our r is 48 m. So we would just plug in 48 m into r which would get squared and then multiplied by pi to give us [tex]7,238.23\ m[/tex].

3Your new mobile phone costs £360.
The probability you leave it on the bus is 0.1.
The probability someone will hand it in to lost property and you will recover it
is 0.4.
The cost of insurance to cover the loss of the phone is £30.
Should you pay for this control measure?
List any assumptions that you make
Assuming you have to pay 30 pounds for somebody handing it in to lost property, you'll have a 0.5 probability that you'll have to pay the 30 pounds if you lose the phone.
Also assuming there are no other ways to lose your phone, you have a 0.5 probability (50% chance?) to lose your phone.
Also assuming the "control measure" is the insurance and you won't have to pay a larger amount, you'll probably be better off paying the 30 pounds instead of the larger amount because you have such a high chance of losing your phone.

The number of times Damian would pick a vanilla-flavored candy from the jar is 8 times.
How many times would Damian pick a vanilla-flavored candy?Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The number of times Damian would pick a vanilla-flavored candy = number of vanilla flavored candy / total number of candies
20 / 125 = 0.16
0.16 x 50 = 8 times

After 1 year, the initial investment increases by 7%, i.e. multiplied by 1.07. So after 1 year the investment has a value of $800 × 1.07 = $856.
After another year, that amount increases again by 7% to $856 × 1.07 = $915.92.
And so on. After t years, the investment would have a value of [tex]\$800 \times 1.07^t[/tex].
We want the find the number of years n such that
[tex]\$856 \times 1.07^n = \$1400[/tex]
Solve for n :
[tex]856 \times 1.07 ^n = 1400[/tex]
[tex]1.07^n = \dfrac74[/tex]
[tex]\log_{1.07}\left(1.07^n\right) = \log_{1.07}\left(\dfrac74\right)[/tex]
[tex]n \log_{1.07}(1.07) = \log_{1.07} \left(\dfrac74\right)[/tex]
[tex]n = \log_{1.07} \left(\dfrac74\right) = \dfrac{\ln\left(\frac74\right)}{\ln(1.04)} \approx \boxed{8.3}[/tex]
Answer:
25 years
Step-by-step explanation:
total = before × percent ( in decimal ) × time
1400 = 800 × 0.07 × t
1400 = 56 × t
1400 ÷ 56 = 25

• A bag contains 5 orange, 3 yellow, and 5 black marbles. What are the odds of picking an orange marble?
Answer:
The odds will be 5/13.
Step-by-step explanation:
There are 13 marbles total in this situation. 5 orange, 3 yellow and 5 black (5+3+5) will give us 13 as our overall total. Now, because we have 5 orange marbles available, we'll write this as a 5/13 odds/ chance of picking an orange marbles because it is how many orange marbles are present over how many marbles there are total.
Also! You can't simplify this any further, thus you'd have 5/13 odds.

Maria and Bridgette both belong to the same public pool and attend swim classes with a coach. Maria pays $105 for her season pass and 6 swim classes. Bridgette pays $135 for her season pass and 9 swim classes. What is an equation for the cost of a season pass and swim classes as a function of the number of swim classes attended? Explain what each variable represents and identify the initial value and the rate of change. Show your work.
Answer:
T = 10s + 45Step-by-step explanation:
Since both Maria and Bridgette belong to the same public pool they pay same rate for season pass and each class.
Let the season pass be y and swim class cost be x.
Then according to given we have the following equations
y + 6x = 105y + 9x = 135Solve the system by elimination, subtract the equations
y + 9x - y - 6x = 135 - 1053x = 30x = 10Find y
y + 6*10 = 105y = 105 - 60y = 45The initial value is 45 and rate of change is 10.
The equation for the total cost would be
T = 10s + 45, where T - total cost, s - number of swim classesRoberta grows pea plants, some in shade and some in sun. she picks 8 plants of each type at random and

The probability that the next customer will pay with cash is 0.55.
What is the formula for probability?Probability is the ratio of the number of favorable events divided by the total outcome.
We have, given that, Tanisha owns a small business selling bagels. She knows that in the last week 61 customers paid cash, 5 customers used a debit card, and 45 customers used a credit card.
The total number of payments is,
61+45+5=111.
We have to find the probability that the next customer will pay with cash as a decimal to the nearest hundredth.
The number of the favorable outcome for the customer will pay with cash is 61, and the total number of outcomes is 111.
Therefore, the probability is,
P(A)=61/111
P(A)=0.5495.
Therefore, the probability of the nearest hundredth is 0.55.

Answer:
0.7°
Step-by-step explanation:
From the figure:
CF = 4000.2 miles, CE = 4000.01 miles
so FT = √CF² - CT², TE = √CE² - CT²
so FT = 40 miles, TE = 8.94 miles
so ½ × 4000.2 × 4000.01
xsin angle FCE = ½ × 4000 × 140 + 8.94
so sin angle FCE = 0.0122
so angle FCE = 0.7°

In a right-angled triangle, the sum of the squares of the three sides is 72. What is the length of the hypotenuse?
Answer:
The hypotenuse has a length of 6
Step-by-step explanation:
Remark
The first step is to create the 2 equations needed to solve this problem.
Then substitute one into the other.
Equations
c^2 + a^2 + b^2 = 72
c^2 = a^2 + b^2
Solution
c^2 + a^2 + b^2 = 72 The sum of the sides each squared of a right triangle = 72
c^2 = a^2 + b^2 The pythagorean theorem says the hypotenuse of the right triangle = the sum of the squares of two smaller sides. You can substitute the hypotenuse squared into the top equation for a^2 + b^2
c^2 + c^2 = 72
2c^2 = 72
c^2 = 36
c = 6. minus 6 is meaningless
