Answer:
12 blueberries and 4 strawberries
Step-by-step explanation:
We can try the guess method.
3:1 3 + 1 = 4 4 is too low. We need a sum of 16.
Multiply both numbers in the ratio by 2.
6:2 6 + 2 = 8 8 is still too low
Multiply both numbers in the ratio by 4.
12:4 12 + 4 = 16 16 is correct.

ENTER THE ANSWER AS AN EXACT DECIMAL OR SIMPLIFIED FRACTION
Answer:
0.8 or 8/10
Step-by-step explanation:
Answer:
4/5 or 0.8
Step-by-step explanation:
so, -4/4 and 1/5 are both already fractions.
160% as a decimal would be 1.6. 1.6 as a fraction would be 8/5.
-4/4 is just -1
-1+1/5+8/5
so, -5/5 +1/5 +8/5
-5/5 plus 9/5
4/5
the answer would be 4/5 or 0.8
Paige earned $15.50 per hour. She received a 15% raise. How much more does Paige earn now per hour?
Answer:
232.5
Step-by-step explanation:
If you take 15.50 and multiply it by 15 you get 232.5 if its wrong my apologies
Answer: $2.33
Step-by-step explanation:
Your formula for percent is % times X = Y.
So you multiply 15% x 15.50 and you get 2.325 and you round it up and the 5 makes your 2 go to a 3 and you get $2.33
X^2+4x+20=12x-5
Solve this equation
Answer:
4 + (or -) 3i
Step-by-step explanation:
Hi!
Alright, so we're going to move all of the variables and constants to one side. Then, using the quadratic formula, we'll find the answer.
1. Move 12x-5 to the left side of the equation by
a. Subtracting 12x from both sides
b. adding 5 to both sides.
1: x^2+4x+20-12x+5
2. Group the common terms
x^2+4x-12x+20+5 --> x^2-8x+25
3. Look at the problem. We can't factor this.
Explanation for why this isn't factorable (you can skip this)
(1) 25 is positive, so its two factors will both be either positive or negative. We're looking for a negative 8, so let's go with negative.
(2) Factors of 25: 1 & 25, 5 &5
Seeing the problem? Ya, none of the factors of 25 sum to eight. So, instead, we're going to use the quadratic formula.
4. So, the quadratic formula: [tex]\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]
Our equation is x^2-8x+25=0
a is the constant in front of the x^2
b is the constant in front of the x
c is the term without any x values
so, a=1, b=-8, and c= 25
Into equation:
[tex]\frac{8+-\sqrt{64-4(1)(25)} }{2a}[/tex]=[tex]\frac{8+-\sqrt{64-100} }{2}[/tex]=[tex]\frac{8+-\sqrt{-36} }{2}[/tex]
8/2 = 4
sqrt(-36) = 6i
6i/2 = 3i (remember, we still have the two in the denominator)
4 + (or -) 3i
Answer:
[tex]x=4+ 3\mathbf{i}[/tex]
[tex]x=4- 3\mathbf{i}[/tex]
Step-by-step explanation:
Solve:
[tex]x^2+4x+20=12x-5[/tex]
Move everything to the left side:
[tex]x^2+4x+20-12x+5=0[/tex]
Simplify:
[tex]x^2-8x+25=0[/tex]
Apply the solver formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Where a=1, b=-8, c=25. Thus:
[tex]\displaystyle x=\frac{8\pm \sqrt{(-8)^2-4(1)(25)}}{2*1}[/tex]
[tex]\displaystyle x=\frac{8\pm \sqrt{64-100}}{2}[/tex]
[tex]\displaystyle x=\frac{8\pm \sqrt{-36}}{2}[/tex]
The solutions are complex numbers:
[tex]\displaystyle x=\frac{8\pm 6\mathbf{i}}{2}[/tex]
Simplifying:
[tex]x=4\pm 3\mathbf{i}[/tex]
Two solutions are found:
[tex]x=4+ 3\mathbf{i}[/tex]
[tex]x=4- 3\mathbf{i}[/tex]

Answer:
I think its b
Step-by-step explanation:
A small company has one color printer and one black-and-white printer, each printing at different rates. The color printer, working for 5 minutes and the black-and-white printer working, working for 3 minutes, print a total of 70 pages. When the black-and-white printer works for 6 minutes and the color printer works for 9 minutes, they print a total of 135 pages. This is modeled by the situation below, where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer 3b + 5c = 70 and 6b + 9c = 135 How many pages per minute does the black-and white printer print?
Answer:
The black-and white printer print can print 15 pages per minute.
Step-by-step explanation:
The given modeled equations are
3b + 5c = 70...(i)
6b + 9c = 135...(ii)
where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.
From equation (i), we have
[tex]3b=70-5c \\\\\Rightarrow b = \frac {70-5c}{3} \cdots(iii)[/tex]
Now, substitute the value of b in equation (ii), we have
[tex]6\times \frac {70-5c}{3}+9c=135 \\\\\Rightarrow 2(70-5c)+9c=135 \\\\\Rightarrow 140 - 10c+9c=135 \\\\\Rightarrow -c=135-140=-5 \\\\\Rightarrow c=5x^{2}[/tex]
By using equation (iii), we have
[tex]b = \frac {70-5\times5}{3}=\frac{45}{3}=15[/tex]
Hence, the black-and white printer print can print 15 pages per minute.
The black-and-white printer can print 15 pages per minute.
Given equations:
[tex]3b+5c=70[/tex] ........(i)
[tex]6b+9c=135[/tex] ........(ii)
Where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.
Solve the system of equations by substitution method
From (ii)
[tex]6b=135-9c\\b=\frac{135-9c}{6}[/tex] ........(iii)
Put the value of b in (i), we get
[tex]3(\frac{135-9c}{6} )+5c=70\\\frac{135-9c}{2} +5c=70\\135-9c+10c=140\\c=5[/tex]
put c = 5 in (iii)
[tex]b=\frac{135-9(5)}{6} =\frac{90}{6} =15[/tex]
Therefore, The black-and-white printer can print 15 pages per minute.

Jesse took out a $14,000 car loan for 5 years at a 7.2% interest rate. Find Jesse's total payment amount for this loan.
Answer:
16,712.38
Step-by-step explanation:
Periodic interest rate 7.2%/12 = 0.6%
First find the monthly payment
M = $14,000 * 0.006(1 +0.006)^60/(1+0.006)^60-1 = 278.54
The total payment is $278.54 * 60= $16,712.38
Jesse's total payment amount for this loan is $16,712.38
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest =P(1+r/n)^rt
We are given that Jesse took out a $14,000 car loan for 5 years at a 7.2% interest rate.
Periodic interest rate = 7.2%/12
= 0.6%
First we need to find the monthly payment
M = $14,000 x 0.006(1 +0.006)^60/(1+0.006)^60-1
M = 278.54
The total payment is
$278.54 x 60= $16,712.38

Jacqueline spent 33.50 to rent a bicycle. The bike rental facility charged $4 per hour and a processing fee of $1.50. For how many hours, x , did jacqueline rent the bicycle
Answer:
8 hours
Step-by-step explanation:
Given that:
Money spent by Jacqueline to rent a bicycle = $33.50
Per hour charges for the bicycle for renting the bicycle = $4
Processing fee charged for renting the bicycle = $1.50
To find:
The number of hours, [tex]x[/tex] for which Jacqueline rented the bicycle.
Solution:
Charges for 1 hour = $4
Charges for [tex]x[/tex] hours = $[tex]4x[/tex]
Processing fee = $1.50
Total fee charged for renting the bicycle is nothing but the sum of processing fee and the charges for [tex]x[/tex] hours charged by the bike rental facility.
Total money spent = Processing Fee + Charges for [tex]x[/tex] hours
Total money spent = 1.50 + 4[tex]x[/tex] = 33.50
[tex]\Rightarrow 4x = 32\\\Rightarrow x = \bold{8\ hours}[/tex]
So, Jacqueline rented the bicycle for 8 hours.

A woman bought 210 oranges for GH¢65.00. she sold all of them at 3 for ¢20.00. how much profit did she make?
Answer:
She made a profit of 1,335 cedis
Step-by-step explanation:
Here, we want to calculate the profit made
Profit is selling price - cost price
Her cost price is 65 credits
For her selling price;
she sells 3 for 20 cedis
So the price she sold 210 will be;
(210 * 20)/3 = 1,400 cedis
So the profit made is;
1,400-65 = 1,335 cedis
