Answer:
The blank in the equation is 1.
x = 7 and the vertical angles measure out to 64 degrees.
Step-by-step explanation:
When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.
Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.
The dimensions of a rectangle are x+3 and x+4. The area of the rectangle is 72. Set up an equation that models this rectangle and solve in order to determine the value of x.
Answer: x = 5
Step-by-step explanation:
The area of a rectangle is the length times the width. Since the dimensions are given as functions of x, youre going to have to use FOIL to combine them, then set that answer equal to the given value of 72.
l*w = (x+3)*(x+4) = x^2 + 7x +12 = 72
Subtract 72 on both sides. There is a reason why we'll do this instead of subtracting 12. The quadratic formula will help us to solve for x.
x^2 + 7x - 60 = 0
Apply the quadratic formula
[tex]\frac{-7 (+/-)\sqrt{7^2-(4)*(1)*(-60} }{2*1} =\frac{-7(+/-)17}{2}[/tex]
We cant have a negative x value because that would result in negative dimensions and a negative area, which is impossible in this context. So you want to add the 17 instead of subtracting it.
x = 5 and x = -12
An alternate way is just factoring the trinomial to:
(x+12)(x-5) = 0

Price: $8.62 per 3 lb of strawberry
How much will it cost to buy 4.2 lb of strawberries? (Round to 2 decimal digits if necessary)
9514 1404 393
Answer:
$12.07
Step-by-step explanation:
The cost is proportional to the weight, so we have ...
dollars/pounds = c/4.2 = 8.62/3
Multiplying by 4.2 gives ...
c = 4.2×8.62/3 = 12.068
The cost of 4.2 pounds of strawberries is $12.07.
Ben sells homemade cards at a craft fair. He wants to earn more than $50 at the fair. He sells his cards for $2 and he has already earned $36. How many cards foes he need to sell to reach his goal? Write and solve an inequality.
Answer:
He must sell 8 cards to reach the minimum goal.
Step-by-step explanation:
Giving the following information:
He wants to earn more than $50 at the fair.
He sells his cards for $2 and he has already earned $36.
First, we need to calculate the money required to reach the minimum goal:
51 - 36= $15
Now, we write the inequality:
2*x >15
x= number of cards sold.
x>15/2
x> 7.5
He must sell 8 cards to reach the minimum goal.

What is the interest earned on $3,000 at a rate of 0.04 for 3 years? (Hint: Use the formula i = prt , where i represents the interest earned, p represents the principal, r represents the rate, and t represents the time.)
$3,360
$3,003.04
$360
$120
Answer:
$360
Step-by-step explanation:
You have to calculate the interest earned on $3,000, at the rate of 0.04 for 3 years.
P= $ 3000, R= 0.04 and t= 3 years.
3000 × 0.04 × 3= $360 (Answer)
Hope that helps
Have a good day :)
Answer:
$360.
Step-by-step explanation:
The interest earned on principal P, at the rate of r for the duration of t years is given by the equation I = Prt ........... (1)
Now, we have to calculate the interest earned on $3000, at the rate of 0.04 for 3 years.
Here, P = $3000, r = 0.04 and t = 3 years.
Hence, from equation (1), Interest earned, I = 3000 × 0.04 × 3 = $360 (Answer)

Answer:
y = 240,000(1.048)^t
Step-by-step explanation:
Initial population: p = 240,000
Annual growth rate: 4.8% = 0.048
Number of years: t
Population in year t: y
y = p(1 + r)^t
y = 240,000(1 + 0.048)^t
y = 240,000(1.048)^t
