1) The figure at the top is a parallelogram; the area is A = bh; where b is the base and h is the height; use properties of special right triangles to find h, and the area of the parallelogram
a) Read the problem once and state what is the problem about?
Answer:
[tex]10 \sqrt{3} {cm}^{2} [/tex]
Step-by-step explanation:
The area of a parallelogram is A=bh.
From the diagram, the base is b=5m
We now use the properties of 30°-60°-90° right angle to find h.
The sides of this triangle is given by x,½x,½x√3
Where x is 4
Therefore we have 4,2, 2√3
So we have h=2√3m
The area now is
[tex]A = 5 \times 2 \sqrt{3} = 10 \sqrt{3} {cm}^{2} [/tex]
a)The problem is about finding area of a plane figure

Answer:
First Problem: $50.15
Second Problem: $20,468
Step-by-step explanation:
First Problem: If the original price is $41.00 and the discount is $6.15
41.00 - 6.15 = $34.85 is the discounted price
34.85 / 41.00 = 0.85 -> this shows the amount that you pay from the original price
So if the other product costs $59.00 you just do 59.00 * 0.85 = $50.15
This shows that %85 of the original cost is what you pay.
Second Problem: So, the first amount sold is 160 tickets and the price for each ticket is $59.50.
160 * $59.50 = $9,520 for the afternoon batch
If they sold %15 more in the evening that means that they sold 160 tickets plus another %15 of the 160.
160 * 1.15 = 184 tickets sold in the evening
184 * $59.50 = $10,948 for the evening batch
So they sold a total of $9,520 + $10,948 = $20,468
Answer:
44) $50.15
45) $20,468
Step-by-step explanation:
44) $ off sweater = 6.15
41.00 - 6.15 = 34.85
6.15 ÷ 41.00 = 0.15 = 15% discount
$59.00 - 15%
$50.15
45)
Afternoon = 160 tickets
Evening = 15% more = 160 + 15% = 184 tickets
160 + 184 = 344 tickets total
344 * $59.50 = $20,468

Is 2(3a-2)+4a equivalent to 10a-2
After simplifying the expression 2(3a-2)+4a, we get 10a-4, which is not equivalent to 10a-2 due to a difference of 2.
Explanation:To determine if the expression 2(3a-2)+4a is equivalent to 10a-2, we must simplify the former expression.
First, distribute the 2 into the parenthesis: 2 × 3a is 6a, and 2 × -2 is -4. So we get 6a - 4.
Next, we add the 4a that is outside the parenthesis to the 6a we got after distribution: 6a + 4a equals 10a.
Now we have 10a - 4. This is close to 10a-2 but there is a difference of 2. Therefore, the two expressions are not equivalent.

Jacqueline wants to make as many identical bouquets as possible using all flowers she has. What is the biggest number of such bouquets can be made out of 42 carnations, 36 tulips and 54 daffodils?
Answer:
6
Step-by-step explanation:
This is a disguised GCF problem. If Jacqueline wants to use all the flowers she has, she must find the greatest common factor of the their numbers.
1. Determine the prime factors of each number and mark those that are common
The prime factors of 42 are 2 × 3 × 7 = 42
The prime factors of 36 are 2 × 2 × 3 × 3 × 3 = 36
The prime factors of 54 are 2 × 3 × 3 × 3 = 54
2. Multiply the common factors
The common prime factors of 42, 36. and 54 are 2 and 3.
The greatest common factor is 2 × 3 = 6.
Jacqueline can make six bouquets, and each will contain seven tulips, six carnations, and nine daffodils.

The difference between two numbers is 52 .Five times the smaller is equal to 4 more than the larger. What are the numbers?
The larger number is 66 and the smaller number is 14.
Step-by-step explanation:
Let,
The larger number = x
The smaller number = y
According to given statement;
x-y=52 Eqn 1
5y = x+4 Eqn 2
From Eqn 2
x = 5y-4 Eqn 3
Putting value of x from Eqn 3 in Eqn 1
[tex]5y-4-y=52\\4y=52+4\\4y=56[/tex]
Dividing both sides by 4
[tex]\frac{4y}{4}=\frac{56}{4}\\y=14[/tex]
Putting y=14 in Eqn 3
[tex]x=5(14)-4\\x=70-4\\x=66[/tex]
The larger number is 66 and the smaller number is 14.

Write a linear equation that passes through the point (2,-9) and has a slope of -5
Answer:
y=-5x+1
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=-5(x-2)
y+9=-5x+10
y=-5x+10-9
y=-5x+1
The linear equation that passes through the point (2, -9) with a slope of -5 is y = -5x + 1.
To find the linear equation, we use the point-slope form of a line, which is:
y - y₁ = m(x - x₁)
Here,
m is the slope and (x₁, y₁) is a point on the line.
Given:
Slope (m): -5Point (x₁, y₁): (2, -9)Substitute the values into the point-slope form equation:
y - (-9) = -5(x - 2)
Simplify the equation:
y + 9 = -5(x - 2)y + 9 = -5x + 10y = -5x + 10 - 9y = -5x + 1So, the linear equation in slope-intercept form is y = -5x + 1.

(x + 1)(x + 8)
Step-by-step explanation:
Given
x² + 9x + 8
Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (+ 9)
The factors are + 1 and + 8, since
1 × 8 = 8 and 1 + 8 = 9, thus
x² + 9x + 8 = (x + 1)(x + 8)

Answer:
6.375 cups of raisins
Step-by-step explanation:
The ratio of raisins to peanuts is 3:2. This is because 0.5 divided by 2 and then multiplied by 3 is equal to 0.75.
So to find the number of raisins we need to divide the number of peanuts by 2 and then multiply it by 3:

$1,225,54
$2,225.54
$225.54
$22,255.40
Answer:
$2,225.54
Step-by-step explanation:
Principal, p = $1000
interest rate r = 16% 0r 0.16
years of deposit, t = 5
Finding ending balance below
Since interest compounded continuously,
Substitute the following values
p = $1000, e = exponent, r = 0.16 and t = 5
B = 1000e^((0.16)(5))
=1000e^(0.8)
=1000 X 2.2255409284924676
=2,225.5409284924676
Which B is approximately $2,225.54
Ending balance =$2,225.54
Assuming the amount of $1,000 was invested at an interest rate of 16%, compounded continuously, for a period of five years, what the ending balance will be is: $2,225.54
p represent Principal = $1000
r represent Interest rate= 16% or 0.16
t represent=5 years
Now let determine the ending balance
Ending balance= $1000e^(0.16)(5)
Ending balance=$1000e^(0.8)
Ending balance=$1000 X 2.2255409284924
Ending balance=$2,225.5409284924
Ending balance=$2,225.54 (Approximately)
Inconclusion if the amount of $1,000 was invested at an interest rate of 16%, compounded continuously, for a period of five years, what the ending balance will be is: $2,225.54
