Answer:
8 gallons of gasoline costs $30.63.
Step-by-step explanation:
Set up a proportion to solve for x, or the cost of 8 gallons of gasoline. The $47.86 goes on top of the first ratio, and 12.5 goes on top of the second. This is because the $47.86 is the cost of the 12.5 gallons of gasoline. Next, put x on the bottom of the first ratio and 8 on the bottom of the second ratio. This is because the amount of money you are trying to find, x, is the cost of the 8 gallons of gasoline. The proportion should look like this: [tex]\frac{47.86}{x} = \frac{12.5}{8}[/tex]
To solve the proportion, use cross multiplication. To do that, multiply 8 by 47.86 to get 382.88. Then, divide 382.88 by 12.5. The answer is 30.6304, so round to the nearest cent to get a total of $30.63.

Sue bought 3.5 yards of material at $8.70 per
yard and 5 yards of lace trim. She spent $32.90 in
total. Calculate the cost of 1 yard of lace trim.
Answer: $.49
step explanation:
Sue bought 3.5 yards of material at $8.70 per yard (3.5x8.70=30.45)
Sue also bought 5 yards of lace trim.
Her total was 32.90 and we want to find out how much the lace trim cost.
We will subtract the initial material to get the subtotal cost for just the lace trim. (32.90-30.45=2.45)
5 yards of lace trim total up to $2.45. To get how much each yard cost we will divide (2.45÷5=.49)
Each yard of lace trim costs $.49 cents
Factor the GCF: 12x2y + 6x2y3 – 9xy? (4 points)
3x^2y(4x2 + 2xy - 3)
3xy(4x + 2xy - 3y^2)
3xy(4x^2 + 2xy – 3y^2)
3x^2y(4x^3y – 2x^2y^2 - 3xy^3)
The greatest common factor (GCF) of the expression 12² + 6²³ − 9 is 3. So, factored form is c) 3xy (4x² + 2xy – 3y²).
To factor out the greatest common factor (GCF) from the expression
12² + 6²³ − 9, we need to identify the highest common factor among the terms.
First, let's list the factors of each term:
12² can be factored into 3 × 2 × 2 × × ×
6²³ can be factored into 3 × 2 × × × × ×
9 can be factored into 3 × 3 × ×
The highest common factor among these terms is 3.
Now, we divide each term by 3:
12² ÷ 3 = 4
6²³ ÷ 3 = 22
9 ÷ 3 = 3
So, the factored expression becomes 3 (4² + 2² −3). This is the result of factoring out the GCF 3 from the given expression.

Solve each pair of equations by substituting
2x + y = 3
4x + 3y = 1
Answer:
the value of x and y is 4 and -5 respectively.
Step-by-step explanation:
from the equation we say let;
2x + y = 3 .............. equation 1
4x + 3y = 1.............. equation 2
from equation 1
2x + y = 3 .............. equation 1
y = 3 - 2x................ equation 3
Substitute for y in equation 2
4x + 3y = 1.............. equation 2
we have,
4x + 3(3- 2x) = 1
4x + 9 -6x = 1
we have to collect the like terms
9-1 = 6x -4x
8 = 2x
divide both sides by 2
8/2 = 2x/2
4 = x
therefore x = 4
put x = 4 in equation 3
y = 3 - 2x................ equation 3
y = 3 - 2(4)
y = 3 -8
y = -5
therefore the value of x and y is 4 and -5 respectively.
to check if your answer is correct, put the value of x and y in any of the equations.
2x + y = 3 .............. equation 1
2(4) + (-5) = 3
8 -5 = 3
3 = 3......................... proved
For which value of x is the relation not a function (5,2), (x,1), (8,6), (9,3)
Answer:
x=5, 8, 9
Step-by-step explanation:
in a function, one x value must be paired with one and only one y value, this means there cannot be two points where x values are the same, however the y values can repeat.
if x = 5, 8, or 9, the relation is not a function because there are 2 same x values.
Find the slope of the line that passes through (-99, -25) and (-98, -62).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
-37
Step-by-step explanation:
Slope = y2 - y1/x2 - x1
Given
x1 = -99
y1 = -25
x2 = -98

Slope = -62 -(-25) /-98 -(-99)
Negative negative becomes positive
= -62 + 25 /-98 + 99
= -37/1
= -37

Trina's car uses 12 gallons of gas to travel 144 miles. If she has 6 gallons of gas in the tank, how much more gas will she need to drive 240 miles?
Answer: 14gallons
Step-by-step explanation:
12gallons/144miles = 1gallon/12miles
Therefore 6gallons = 12*6 = 72miles.
In order to cover 240miles, she will need 240/12 = 20gallons.
20-6 = 14gallons
She will need 14gallons of gas more.
If Abby rolls two number cubes a hundred times, about how many times would she expect a product greater than 10.
Answer:
20 times ??
Step-by-step explanation:
Abby would expect to roll a product greater than 10 about 42 times in 100 rolls of two number cubes.
To determine how many times Abby would expect to roll a product greater than 10 when rolling two number cubes (dice) a hundred times, we can use probability.
Each number cube has six sides, numbered 1 through 6. When two dice are rolled, the possible products range from 1 (1*1) to 36 (6*6).
To find the probability of getting a product greater than 10, we can list out the combinations that result in products greater than 10:
(2, 6), (3, 5), (3, 6), (4, 4), (4, 5), (4, 6), (5, 3), (5, 4), (5, 5), (5, 6), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)
That's a total of 15 combinations out of 36 possible combinations.
So, the probability of rolling a product greater than 10 is [tex]\( \frac{15}{36} \).[/tex]
To find out how many times Abby would expect this to happen in 100 rolls, we multiply the probability by the number of trials:
[tex]\[ \text{Expected occurrences} = \text{Probability} \times \text{Number of trials} \][/tex]
[tex]\[ \text{Expected occurrences} = \frac{15}{36} \times 100 \][/tex]
[tex]\[ \text{Expected occurrences} \approx \frac{5}{12} \times 100 \][/tex]
[tex]\[ \text{Expected occurrences} \approx 41.67 \][/tex]
So, Abby would expect to roll a product greater than 10 approximately 42 times in 100 rolls.

cot(x)=-3. find sin(x)
Answer:
sin(x)=1/[tex]\sqrt10[/tex]
Step-by-step explanation:
The trigonometric identities involve trigonometric functions. Here we will be using Trigonometric identity
sin²x = 1 /( 1+cot²x )
now cot(x)= -3
⇒ cot²x= (-3)²
⇒ cot²x= 9
sin²x= 1/( 1+9)
⇒ sin²x = 1/10
taking under root on both the sides we get
√sin²x=[tex]\sqrt1[/tex]/[tex]\sqrt10[/tex]
⇒ sin(x)=± 1/[tex]\sqrt10[/tex]
an box of oranges weighs 4 kg an one orange weighs 80 grams how many oranges are in the box
Answer:
50 Oranges
Step-by-step explanation:
4 kg = 4000 grams because 1 kg = 1000 grams.
4000 grams divided by 80 grams gives us the number of oranges in the box since each orange weighs 80 grams.
4000/80 = 50.
Answer:
50 oranges
Step-by-step explanation:
First we need to know the conversion measure.
1kg=1000grams
And if a box is 4kg heavy, it means only oranges weighing 4 times 1000grams can fill it up.
If an orange now weigh 80grams. It means how many oranges will measure up to 1000grams.
1000/80 = 50
50 oranges, each weighing 80grams will fill up a box to weigh 4kg

Louise sold 414 soft pretzels. If she sold them in groups of 18 soft pretzels, how many groups did she sell?
Answer:
23 groups :)
Step-by-step explanation:
Answer:
23
Step-by-step explanation:
Ok so heres the deal: You want to somehow take all 414 of those delicious pretzels and put them into x groups of 18. To do that you would divide 414 by the number of groups (x).
414/x=18
To solve this you just have to get x by itself.
So, multiply both sides by x.
414=18x.
Now divide by 18
414/18=x
23=x

WHAT WOULD THIS BE? I DONT UNDERSTAND IT
Answer:
The answer would be x=7.3 cm
Step-by-step explanation:
Since you are using the angle of 20 degrees and you have the measure of 10 cm for its adjacent side, solving for x would mean you would use tan.
20=x/10
10*20tan=x
200tan=x

Cual es el volumen en metros cúbicos y en litros de 300 N de aceite de oliva cuyo peso especifico es de 9016 N/ m3
SPANISH
Como el peso específico del objeto es Y = 9016 N / m ^ 3, puede ver que será Y = 300 N / V m ^ 3
V (m ^ 3) = 300 N / (9016 N / m ^ 3)
V (m ^ 3) = 0, =. 033 m ^ 3
1 Litro es 0,001 m ^ 3
(.033 m ^ 3) * (1 L / 0,001 m ^ 3) = 35,937 L
ENGLISH
Since the specific weight of the object is Y = 9016 N/ m^3 you can see that it will be Y = 300 N / V m^3
V(m^3) = 300 N / (9016 N/m^3)
V(m^3) = 0,=.033 m^3
1 Litro es 0,001 m^3
(.033 m^3) * (1 L / 0,001 m^3) = 35,937 L

The specific weight is the weight of the per unit volume of a material. The volume of the olive oil is 34 L.
What is specific weight?The specific weight is the weight of the per unit volume of a material. It is given by the formula,
[tex]\rm Specific\ Weight, \gamma= Density \times g = \dfrac{Weight}{Volume}[/tex]
As the weight of the oil is given and the specific density is also given, therefore, we can find volume as,
[tex]\rm \gamma = \dfrac{Weight}{Volume}\\\\\rm 9016= \dfrac{300}{Volume}\\\\Volume = \dfrac{300}{9016}\\\\Volume = 0.0333\ m^3[/tex]
Now, we know that 1 m³ = 1000 litres, therefore,
[tex]\rm Volume = 0.034\ m^3\\\\Volume = (0.034 \times 1000)\ liters\\\\Volume = 34\ liters[/tex]
