Answer:
the answer is 1 and 7
Step-by-step explanation:
4 times 2 is 8 -7 =1
6 times 2 =12 -5 =7
Answer:
First problem equals 1 and second problem equals 7.
First multiply 4x2 to get 8, then subtract it by 7. That would leave you with 1.
Now, 6x2 would be 12 minus 5 which would equal 7.

Answer:
75
Step-by-step explanation:
If the triangles are similar, it means the ratio between the two give sides is the same. As seen from the smaller triangle the ratio of the two top sides would be 16:50 or 8:25.
Since the first side of the bigger triangle (24) is three times 8 (it's ratio side), then the other side must be 3x25 = 75, which maintains the ratio 8:25 between the two sides (24:75).
Hope this helped!

The amount of water in reservoirs is often measured in acre-ft. One acre-ft is a volume that covers an area of one acre to a depth of one foot. An acre is 43,560 ft2. Find the volume in SI units of a reservoir containing 46.0 acre-ft of water.
Answer:
56740.15908m³
Approximately to the nearest whole number, the volume of 46 acre-ft of reservoir = 56740m³
Step-by-step explanation:
1 meter = 3.28084ft
1 acre = 43,560 ft²
Therefore, using our unit conversion, the volume in S.I units of a reservoir containing 46 acre- ft of water is calculated as :
46 acre - ft × (1 meter/3.28084ft) × (43,560ft²/1 acre) × (1 meter/3.28084ft)²
= 2003760/35.314670112
= 56740.15908m³
Approximately to the nearest whole number, the volume of 46 acre-ft of reservoir = 56740m³

Answer:
[tex]\frac{PQ}{DE}[/tex] = [tex]\frac{4}{6}[/tex]
Step-by-step explanation:
Given
Δ PQR ~ Δ DEF
Then the ratio of corresponding sides are equal
The corresponding letters in the names of the triangles gives the corresponding sides.
Thus PQ/DE, QR/EF, PQ/DF
In this case
[tex]\frac{PQ}{DE}[/tex] = [tex]\frac{4}{6}[/tex]

3. Given: a+b=12 and ab=9
Use (a + b)2 to find a² +bº. (Do not solve for a and b individually)
Answer:
a²+b²=126
Step-by-step explanation:
(a+b)²=a²+b²+2ab
(12)²=a²+b²+2×9
144=a²+b²+18
a²+b²=144-18=126
Find sets of three consecutive odd integers whose sum is between 100 and 115
Answer:
33, 35, 37
Step-by-step explanation:
Consecutive: in a row
Odd: any number not evenly divisible by 2
Integers: Whole numbers
Sum: the answer to an addition problem
So, 100 is close to 30*3, so start there and move on. It has to be a little more, so start at 31, 33, and 35, but it's only 99, so you need something a little more. Check 33, 35, and 37 to be sure, and you've got your answer!

Mr. Green's lawn mower holds 600 milliliters of gasoline in the tank. He just filled his 6 liter gas can at the station. How many times will he be able to fill his lawn mower tank from the gas can?
Answer:
10 times.
Step-by-step explanation:
Since 1 liter = 1000 milliliters, we can say that 600 milliliters is equal to 0.6 liters because 600/1000 = 0.6
Since the gas can holds 6 liters, and the lawn mower holds 0.6 liters, 6/0.6 = 10.
So, he can fill his lawn mower 10 times with the gas can
Mr Green can fill his lawn 10 times
the first step is to convert the milliliters to liters
600 milliliters to liters
= 600/1000
= 0.6 liters
the number of times can be calculated as follows
= 6/0.6
= 10
hence it will take Mr. Green 10 times to fill his lawn mower

Answer:
C
Step-by-step explanation:
Given
- [tex]\frac{1}{4}[/tex] (12x + 8) ≤ - 2x + 11 ← distribute parenthesis on left side
- 3x - 2 ≤ - 2x + 11 ( add 3x to both sides )
- 2 ≤ x + 11 ( subtract 11 from both sides )
- 13 ≤ x , thus
x ≥ - 13
Since x can equal - 13 then a solid circle at - 13 represents the solution
Since x greater than - 13 then the arrow is facing to the right of - 13 on the number line.
Then the graph representing the solution is C

Suppose you have 20 coins that total $3.00. Some coins are nickels and some are quarters. Which of the following pairs of equations would you use to find out how many of each coin you have?
Answer:
Step-by-step explanation:
n + q = 20
.05n + .25q = 3.00
5n + 25q = 300
n + q = 20
5n + 25q = 300
-5n - 5q = -100
20q = 200
q = 10 quarters
n + 10 = 20
n = 10 nickels
(10 nickels, 10 quarters)

If the cost, C, for manufacturing x units of a certain product is given by C=x2+10x+45, find the number of units manufactured at a cost of $ 10,020.
Answer: 95 units.
Step-by-step explanation:
The cost of making x units is:
C(x) = x^2 + 10*x + 45.
Now, if the cost is $10,020, then we can solve this for x as:
C(x) = 10,020 = x^2 + 10*x + 45
x^2 + 10*x + 45 - 10,020 = 0
x^2 + 10*x - 9,975 = 0
Now, remember that for a quadratic equation:
a*x^2 + b*x + c = 0
the solutions are:
[tex]x = \frac{-b +-\sqrt{b^2 - 4*a*c} }{2*a}[/tex]
In this case the solutions are:
x = [tex]x = \frac{-10 +-\sqrt{10^2 - 4*1*(-9,975)} }{2*1} = \frac{-10 +- 200}{2}[/tex]
Then we have two solutions, one for each sign:
x = (-10 -200)/2 = -110
x = (-10 + 200)/2 = 95
Here we must choose the positive option, as x represents a positive quaintity.
Then the number of units manufactured is 95.

What is 3X to the second power plus 4X -3+ negative 4X to the second power minus 2X -4 in polynomial form
Answer:
The polynomial form of the expression is: 25·X² + 2·X + 2.
Step-by-step explanation:
The expression that can be formed using the provided data is:
[tex](3X)^{2}+(4X-3)+(-4X)^{2}-(2X-4)[/tex]
Simplify the expression to get a result in polynomial form as follows:
[tex](3X)^{2}+(4X-3)+(-4X)^{2}-(2X-4)[/tex]
[tex]=9X^{2}+4X-3+16X^{2}-2X+5\\\\=(9+16)X^{2}+(4-2)X+(5-3)\\\\=25X^{2}+2X+2[/tex]
Thus, the polynomial form of the expression is: 25·X² + 2·X + 2.
