if n = 4; m=10 how do you solve ?
Answer:
7(4) - (10+18)
28 - 28
0
Step-by-step explanation:
Step-by-step explanation:
okay, 7 (n) if n = 4 that means 7 times 4 so that equals 28 BUT we do (m + 18) first so if m= 10 that means (10 + 18) would be 28, so
28 - 28= 0
The probability of choosing a green grape out of the bag that contains red and green grapes without looking is StartFraction 11 over 15 EndFraction. Which term best describes this probability?
impossible
unlikely
likely
certain
Answer:
likley
Step-by-step explanation: edge 2021 on the quiz for me its question 6
Answer:
C. likely
Step-by-step explanation:
It is likely because if the bag holds red and green grapes then its not impossible to get a green grape because there are green grapes in the bag. It is not unlikly because there are 11/15 green grapes there, so there are more green grapes than red. But its still not certain that you will get a green grape, remember there are still quite a few red grapes too! So you would likely get a green grape.

A,B,C and D lie on a circle, center O, radius 8cm. AB and CD are tangents to a circle, center O, radius 4cm.
ABCD is a rectangle. a) calculate the distance AE
b) calculate the shaded area
Answer:
a) [tex]AE=4\sqrt{3}[/tex]
b) [tex]A_s=16(4\sqrt{3}-\pi)\ cm^2[/tex]
Step-by-step explanation:
Lines in a Circle
(a)
Points AEO form a right triangle, which hypotenuse is the radius of the larger circle (8 cm) and one of its legs is the radius of the smaller circle (4 cm).
Thus, the distance AE is calculated by using the Pythagora's Theorem:
[tex]AE^2=8^2-4^2[/tex]
[tex]AE^2=64-16=48[/tex]
[tex]AE=\sqrt{48}[/tex]
Since 48=16*3:
[tex]AE=\sqrt{16}\sqrt{3}[/tex]
[tex]\boxed{AE=4\sqrt{3}}[/tex]
(b)
The shaded area is the area of the rectangle ABCD minus the area of the smaller circle:
[tex]A_s=A_r-A_c[/tex]
The rectangle has a length of twice AE:
[tex]L=8\sqrt{3}\ cm[/tex]
And a width equal to the diameter of the smaller circle:
[tex]W=8\ cm[/tex]
The area of the rectangle is:
[tex]A_r=8\sqrt{3}\ cm*8\ cm[/tex]
[tex]A_r=64\sqrt{3}\ cm^2[/tex]
The area of the smaller circle is:
[tex]A_c=\pi\ r^2[/tex]
[tex]A_c=\pi\ 4^2\ cm^2[/tex]
[tex]A_c=16\pi\ cm^2[/tex]
Thus, the shaded area is:
[tex]A_s=(64\sqrt{3}-16\pi)\ cm^2[/tex]
Factoring:
[tex]\boxed{A_s=16(4\sqrt{3}-\pi)\ cm^2}[/tex]
a. the length of AE is: 6.9 cm
b. the shaded area is: 60.13 sq. cm.
Recall:
Area of rectangle = length × widthArea of circle = πr²a. Find AE:
Considering right triangle AOE, apply the Pythagorean Theorem to find AE, given that,
EO = 4 cm
AO = 8 cm
Thus:
AE = √(AO² - EO²)
AE = √(8² - 4²)
AE = 6.9 cm
b. Shaded Area = Area of rectangle - area of circle
Area of rectangle = length × width = 2(6.9) × 2(4) = 110.4 sq. cm
Area of circle = π(4)² = 50.27 sq. cm
Shaded Area = 110.4 - 50.27 = 60.13 sq. cm.

The side length of a square is 8 cm. what is the area? What is the perimeter?
Answer:
Area = 64 cm² ; Perimeter = 32 cm
Step-by-step explanation:
Since we know that the side lengths of a square are all equal, this means that all 4 square lengths are 8 cm. Knowing that, we could simply square one of the side lengths to find the area:
8² = 64 cm²
To find the perimeter, just add all the side lengths. There are four sides to a square so we can just multiply the side length by 4:
8 · 4 = 32 cm

Mina says triangle A with angles
measuring 34° and 57° is similar to
triangle B with angles measuring 57°
and 89º. Is Mina correct?
Answer:
Yes, Mina is correct
Step-by-step explanation:
Let the triangles be A and B
Given
Triangle A:
[tex]Angles = 34, 57[/tex]
Triangle B:
[tex]Angles = 89, 57[/tex]
Required
Is Mina's claim correct?
First, we calculate the third angle in both triangles.
For A:
[tex]Third\ Angle = 180 - 34 - 57[/tex]
[tex]Third\ Angle = 89[/tex]
For B:
[tex]Third\ Angle = 180- 89 - 57[/tex]
[tex]Third\ Angle = 34[/tex]
For triangle A, the angles are: 34, 57 and 89
For triangle B, the angles are: 34, 57 and 89
Since both triangles have the same angles, then by the postulate of AAA (Angle-Angle-Angle), the triangles are similar.
2. Almost everyone has played the rock-paper-scissors game at some point. Two players face each
other and, at the count of 3, make a fist (rock), an extended hand, palm side down (paper), or a
"V" with the index finger and middle fingers (scissors). The winner is determined by these rules:
rock smashes scissors, paper covers rock, and scissors cut paper. If both players choose the
same object, then the game is a tie. Suppose that Player 1 and Player 2 are both equally likely to
choose rock, paper, or scissors.
a) Give a probability model for this chance process.
b) Find the probability that Player 1 wins the game on the first throw.
Answer:
a) Let's suppose that player 1 chooses rock, and the selection of player 2 can be thought as random.
If player 2 randomly selects rock, the result of the game is a draw.
if player 2 randomly selects papers, player 1 loses.
if player 2 randomly selects scissors, player 1 wins.
Then we have 3 options with the same probability, that will be:
1/3
This is, the probability of winning is equal to the quotient between the number of outcomes that make player one win (1, in this case, scissors) and the total number of outcomes (3) = 1/3
the probability of a draw is equal to the quotient between the number of outcomes that make a draw (1, in this case, rock) and the total number of outcomes (3) = 1/3
the probability of losing is equal to the quotient between the number of outcomes that make player one lose (1, in this case, paper) and the total number of outcomes (3) = 1/3
And remember that this will be the same for any selection of the player 1.
b) As we already found, the probability of winning for any selection is 1/3 = 0.333..

Matthew has n nickels and d dimes. He has a minimum of $1 worth of coins
altogether. Write this situation as an inequality.
Answer: [tex]5n + 10d \ge 100[/tex]
===============================================
Explanation:
5n represents the value of all the nickels, where n is the number of nickels. Let's say he had 8 nickels. This would mean 5n = 5*8 = 40 cents is from just the nickels.
The 10d represents the value of all the dimes. For example, if he had d = 2 dimes, then he has 20 cents from those dimes because 10d = 10*2 = 20.
Combining the two expressions leads to 5n+10d as the total value of both types of coins. This total value is in cents. We want this value to be 100 cents or more. This is why we set 5n+10d to be greater than or equal to 100. That's how we arrive to [tex]5n+10d \ge 100[/tex]
Optionally we can divide each term by 5 to get [tex]n + 2d \ge 20[/tex] ,but I'll put the other inequality as the answer because it seems more descriptive in my opinion. Keeping 5n shows each nickel is 5 cents, and 10d shows each dime is 10 cents. Something like n+2d loses a bit of its descriptive nature.
The inequality for the given situation is 5n+10d≥100.
Given that, Matthew has n nickels and d dimes. He has a minimum of $1 worth of coins altogether.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
We know that,
A nickel is worth 5 cents. A dime is worth 10 cents. A dollar is worth 100 cents.
Now, the inequality 5n+10d≥100
Therefore, the inequality for the given situation is 5n+10d≥100.

If a credit card company charges 13.5% yearly interest, which of the following calculations would be used in the process of calculating the monthly interest rate?
Answer:
(1.135)^[tex]^1/12[/tex]
Step-by-step explanation:
The monthly interest rate is 1.125%
What is rate of change?
The rate of change of a function is the rate at which the output values change over the input value.
The rate of change of a function is one degree less than the actual function.
Here, it is given that :
a credit card company charges 13.5% yearly interest
therefore, to find the rate of interest charged per month divide 13.5% with 12 :
rate of interest charged per month = 13.5%/12
rate of interest charged per month = 1.125%
Therefore, the monthly interest rate is 1.125%

Sheila can ride her bicycle 6,000 meters in 15 minutes. How far can she ride her bicycle in 3 minutes? please help im retarted
Answer:
The answer is 1,200 meters
Step-by-step explanation:
So what I did was find the rate so we want to know how much Sheila can do in just 1 minute first so you would have to do 6,000/ 15 which gives you 400 so he does 400 meters in just 1 minute. So then you would have to multiply 400 by 3 which gives you 1,200, making that your answer.
hope that helped!
Answer: 800 meters
Step-by-step explanation:
We first find the speed of Sheila by the speed equation, which is:
v =d/t
d is the total distance traveled
t is the total time taken
And so, we get:
v = 6000m/ 15min
= 400m/min
Now, we find the distance traveled in 2 minutes by solving for distance in the speed equation, which becomes:
d=v⋅t
Inputting our values, we get:
400m/min ⋅ 2min=800
