Step-by-step explanation:
If Aleah buys 2 DVDs for $6 and 2 CDs for $8 we can well assume that the DVDs are $3 dollars each and the CDs are 4 Dollars Each. If ling wants to buy 4 DVDs You would multiply how many DVDs she's buying with the price of the DVDs so (4x3=12) so Ling would have to pay $12 for the DVDs and $8 on the CDs
Pierre wants to spend $20 so with the previous information we can come to the solution that Pierre can buy 4 DVDs and 2 CDs for $20.
7th grade - Find the surface area of this trapezoidal prism. Please help ASAP I'll give brainliest!!!
Answer:
[tex]380 \text{ m}^2[/tex]
Step-by-step explanation:
To find the surface area of the trapezoidal pyramid, we can use the formula:
[tex]SA = 2(b) + (p \cdot d)[/tex],
where [tex]b[/tex] is the area of the base, [tex]p[/tex] is the perimeter of the base, and [tex]d[/tex] is the prism's depth.
First, we should find the area of the base using the area of a trapezoid formula.
[tex]A_\text{trap} = \dfrac{b_1 + b_2}{2} \cdot h[/tex]
[tex]b = \dfrac{15 + 5}{2} \cdot 7[/tex]
[tex]b = 10 \cdot 7[/tex]
[tex]b = 70 \text{ m}^2[/tex]
Now, we can plug the given dimensions along with the base area into the surface area formula.
[tex]SA = 2(b) + (p \cdot d)[/tex]
[tex]SA = 2(70) + ([15 + 10 + 5 + 10] \cdot 6)[/tex]
[tex]SA = 140 + (40 \cdot 6)[/tex]
[tex]SA = 140 + 240[/tex]
[tex]\boxed{SA = 380 \text{ m}^2}[/tex]

Step-by-step explanation:
Arrange the expressions below in order from least to greatest. Place the least at the top and greatest at the bottom. (72÷8)−2×3+1 72÷(8−2)×3+1 72÷(8−2)×(3+1) 72÷8−2×(3+1) (pls show me a pitcher or something that is right!)
Least
72 ÷ 8 - 2 × (3 + 1) = 1
(72 ÷ 8) - 2 x 3 + 1 = 4
72 ÷ (8 - 2) × 3 + 1 = 37
72 ÷ (8-2) × (3 + 1) = 48
Greatest
To solve all of these, just follow the PEMDAS format (Parenthesis, Exponent, Multiply, Divide, Add, and Subtract)
Or just punch it in a calculator :)
Answer:
72 ÷ 8 - 2 × (3 + 1) = 1
(72 ÷ 8) - 2 x 3 + 1 = 4
72 ÷ (8 - 2) × 3 + 1 = 37

The wheels on Noah's bike have a circumference of about 6 feet.
How far does the bike travel as the wheel makes 12 complete rotations?
Show your work
Answer:
72 feet
Step-by-step explanation:
Because the circumference is 6 feet, with every complete rotation, the bike travels 6 feet. Therefore, the bike will travel 72 feet when the wheel makes 12 complete rotations.

Regina kept track of the points she scored during her team’s first eight basketball games. What is Regina’s mean score?
Responses
A 3939
B 1616
C 3737
D 1313
E 17
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
Could someone explain this?
Answer:
You must find the maximum i.e. the highest score and the minimum i.e. the least score.
In the given question, the lowest score is 4.
the highest score is 50.

Step-by-step explanation:
You want the probability of rolling a sum of 5 when you roll two dice.
Sum of 5There are 4 outcomes that have a sum of 5 when rolling two dice:
(1, 4), (2, 3), (3, 2), (4, 1)
There are 36 total possible outcomes, so the probability of rolling a 5 is ...
P(5) = 4/36 = 1/9
The probability of rolling a sum of 5 is 1/9.

How far did I travel to reach my destination on each day of my three-day Trip? a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination. b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination. c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
Answer: 81 miles
Step-by-step explanation:
The total distance traveled on the three-day trip is: 81 miles.
How did we get the value?Denote the total distance of each day's journey by D1, D2, and D3, respectively. Then write equations based on the given identities:
a. (5/8)D1 + 15 = D1
(3/8)D1 = 15
D1 = 40 miles
So, the total distance traveled on Day 1 is 40 miles.
b. 18 + (2/5)D2 = D2
(3/5)D2 = 18
D2 = 30 miles
So, the total distance traveled on Day 2 is 30 miles.
c. (5/11)D3 + 6 = D3
(6/11)D3 = 6
D3 = 11 miles
So, the total distance traveled on Day 3 is 11 miles.
Therefore, the total distance traveled on the three-day trip is:
40 + 30 + 11 = 81 miles.

six times the sum of a number and 4 equals 5. Please turn it into an equation :}
Answer:
6(x + 4) = 5
Step-by-step explanation:
We can break this sentence down into individual operations:
"six times" → this means 6 multiplied by some quantity
6 · ()
"the sum of a number and 4" → this is the quantity that we can put inside the parentheses (Note that "a number" is represented as a variable x, and a "sum" is the result of the addition of multiple numbers.)
6 · (x + 4)
"equals 5" → this is self-explanatory; the expression above is equal to 5
6(x + 4) = 5
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
Note that multiplication with a value inside parentheses is implied.
For example,
4(5) = 4 · 5 = 20
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
We can solve for x in this equation to solve for "a number".
6(x + 4) = 5
↓ applying the distributive property ... a(b + c) = (a · b) + (a · c)
6x + (6 · 4) = 5
↓ simplifying
6x + 24 = 5
↓ subtracting 24 from both sides
6x = -19
↓ dividing both sides by 6
x = -19/6

Answer: 540.4 mm squared
Step-by-step explanation:
Since there are 5 triangles, we can find the area of each one and multiply it by 5:
(bh)/2 * 5
the base is 8 because in an isosceles triangle, you divide the bottom side by 2
(2*20)/2 * 5 =
20 * 5 =

Answer:
x = 10
The shaded angles are each 31 degrees.
Step-by-step explanation:
I don't know if you are being asked to solve for x or the shaded angle, so we'll solve for both.
Those 2 shaded angles are equal to each other. So set them equal to each other & solve for x.
91-6x = 4x-9
91+9 = 4x+6x
100 = 10x
10 = x
Now substitute x=10 to find the measure of the shaded angles (which are equal).
91-6x = 91-6(10) = 91-60=31
The shaded angles are both 31 degrees .

I am unsure about number 1, but for number 4, you have to fund the unit rate.
Answer:
Answer for Number 1: 54 1/2
Answer for Number 4: $2.36
Step-by-step explanation:
Explanation for number 1:
1. length x width = area right? So area divided by length = width!
159 3/8 divided by 18 3/4 = 8 1/2
2. width + width + length + length = perimeter right? Now you know the
width, you can do...
8 1/2 + 8 1/2 + 18 3/4 + 18 3/4 = 54 1/2
Explanation for number 4:
1. You know that 4 cup = 1 quart right?
9.44 = 1 quart
2. So you divide it:
9.44 / 4 = $2.36
Write this number in scientific notation.
Thank you!
Answer:To write the number 0.0000149 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.
First, we move the decimal point to the right until there is only one non-zero digit to the left of the decimal point, which gives us:
1.49 × 10^-5
Since we moved the decimal point 5 places to the right, the exponent of 10 is negative 5.
Therefore, the scientific notation of 0.0000149 is 1.49 × 10^-5.
Step-by-step explanation:
Answer:
1.49×10^-5
Step-by-step explanation:
0.0000149=1.49×10^-5
it's to the power of -5 because it's a decimal number not a whole number
When playing a board game, Leilani rolls a number cube twice to determine her next move. In her past 10 moves, she’s rolled two 5s once. How many times does she expect to again roll two 5s in her next 30 moves? Which statement compares this prediction to the theoretical probability of rolling two 5s.
Answer: Leilani has the probability of rolling two 5s three times on her next 30 moves.
Step-by-step explanation: If on average Leilani rolls once in 10, then we can predict that she will at least roll 3 in 30.

Answer:
40 in.²
Step-by-step explanation:
First, you have to find the area of the triangle, which you then multiply by 4 (because there are 4 triangles):
A=1/2(bh)
A=1/2(3x4)
A=1/2(12)
A=6
6x4=24 in.²
Next, you have to find the area of the square:
A=bh
A=4x4
A=16
Now, add 24 and 16 together to get your answer of 40 in.².
