Rajeev walked 7/8 of a mile in 1/4 of an hour. What was the speed in miles per hour?
Answer:
Rajeev walked at 3.5 miles per hour of speed
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Distance Rajeev walked = 7/8 of a mile = 0.875 miles
Time of walking = 1/4 of an hour = 15 minutes
2. What was the speed in miles per hour?
Let's use the Direct Rule of Three for answering this question, as follows:
Distance in miles Time in minutes
0.875 15
x 60
*************************************************
15x = 0.875 * 60
15x = 52.5
x = 52.5/15
x = 3.5

Hugo is pumping regular gas into his truck.Write and wolve an absolute value equation to represent how many galloons of gas will he pumped when the total is $25 plus or minus $0.50
Please, find attached the picture with the whole question.
Answer:
[tex]9.8gallons\leq x\leq 10.2gallons\\ \\ \ [9.8gallons,10.2gallons][/tex]
Both are different forms to represent the same: the amount of gas is between 9.8 gallons and 10.2 gallons, including the borders.
Explanation:
1. Relation between the number of gallons of gas pumped and the total amount paid:
[tex]Number\text{ }of\text{ }gallons=amount\text{ }paid(\$)/price(\$/gallon)[/tex]
2. Conversion
The amount paid is said to be $ 25 ± $0.50
To transform that into number of gallons, divide by the price of the regular gas: $2.50/gallon
[tex]Number\text{ }of\text{ }gallons=\$25/(\$2.50/gallon)\pm$0.50/(\$2.50/gallon)[/tex]
[tex]Number\text{ }of\text{ }gallons=10gallons\pm0.2gallon[/tex]
3. Absolute value equation (inequality)
10 gallons ± 0.2 gallons converted to an absolute value inequality is:[tex]|x-10gallons|=0.2gallons[/tex]
Solution:
[tex]-0.2\leq x-10\leq 0.2[/tex]
[tex]-0.2+10\leq x\leq 0.2+10[/tex]
[tex]9.8\leq x\leq 10.2[/tex]
Hence, the solution is:
[tex]9.8gallons\leq x\leq 10.2gallons\\ \\ \ [9.8gallons,10.2gallons][/tex]
The absolute value equation that represents how many gallons of gas Hugo will pump, assuming a cost of $1.60 per gallon, is |1.6g - 25| ≤ 0.50. Solving this, we find Hugo will pump between approximately 15.31 and 15.94 gallons of gas based on his budget of $25 plus or minus $0.50.
Explanation:Given that Hugo is pumping regular gas into his truck and the total amount he is willing to spend varies between $24.50 and $25.50, we can create an absolute value equation to model this. Assuming the cost per gallon is $1.60, we want to find the number of gallons, represented by 'g', such that the absolute difference between the cost of g gallons and $25 is not more than $0.50.
The absolute value equation would, therefore, be: |1.6g - 25| ≤ 0.50. We can solve this as a compound inequality: -0.50 ≤ 1.6g - 25 ≤ 0.50.
Solving for 'g' in this inequality, we find: 15.3125 ≤ g ≤ 15.9375. This means Hugo will pump between approximately 15.31 and 15.94 gallons of gas.

family has an annual income of $23 comma 400. Of this, one fourth
is spent for food, one fifth
for housing, one tenth
for clothing, one ninth
for savings, one fourth
for taxes, and the rest for other expenses. How much is spent for each?
$
nothing is spent for food.
Amount spent for food = $5850, housing = $4680, clothing = $2340, savings = $2600, taxes = $5850, expenses = $2080.
Step-by-step explanation:
Step 1:
Given details are Total Income = $23,400
Step 2:
Amount spent for food, F= 1/4th of 23,400 = [tex]1/4 \times 23400[/tex]
= $5850
Step 3:
Amount spent for housing, H = 1/5th of 23,400 = [tex]1/5 \times23400[/tex]
= $4680
Step 4:
Amount spent for clothing, C = 1/10th of 23,400 = [tex]1/10 \times 23400[/tex] = $2340
Step 5:
Amount spent for savings, S = 1/9th of 13,400 = [tex]1/9\times 23400[/tex] = $2600
Step 6:
Amount spent for taxes, T = 1/4th of 23,400 = [tex]1/4 \times 23400[/tex] =$5850
Step 7:
Find amount spent on other expenses by totaling all expenditures and subtracting from the annual income.
Annual Income = F + H + C + S + T + E
Amount spent on other expenses, E = 23400 - (5850 + 4680 + 2340 + 2600 + 5850)
E = 23400 - 21320
E = $2080

x-9/3=56/x+4 solve for x
Answer:
x = sqrt(273)/2 - 1/2 or x = -1/2 - sqrt(273)/2
Step-by-step explanation:
Solve for x:
x - 3 = 56/(x + 4)
Cross multiply:
(x - 3) (x + 4) = 56
Expand out terms of the left hand side:
x^2 + x - 12 = 56
Add 12 to both sides:
x^2 + x = 68
Add 1/4 to both sides:
x^2 + x + 1/4 = 273/4
Write the left hand side as a square:
(x + 1/2)^2 = 273/4
Take the square root of both sides:
x + 1/2 = sqrt(273)/2 or x + 1/2 = -sqrt(273)/2
Subtract 1/2 from both sides:
x = sqrt(273)/2 - 1/2 or x + 1/2 = -sqrt(273)/2
Subtract 1/2 from both sides:
Answer: x = sqrt(273)/2 - 1/2 or x = -1/2 - sqrt(273)/2
To solve the equation x - 9/3 = 56/x + 4 for x, multiply both sides by x, distribute and simplify, factor out x, set each factor equal to zero, and solve for x to get the solutions 0 and 63.
Explanation:To solve the equation x - 9/3 = 56/x + 4 for x:
Multiply both sides by x to get rid of the fraction: x(x) - 9/3(x) = 56 + 4(x)Distribute and simplify: [tex]x^2 - 3x = 56x + 4x[/tex]Combine like terms: [tex]x^2 - 63x = 0[/tex]Factor out x: x(x - 63) = 0Set each factor equal to zero: x = 0 or x - 63 = 0Solve for x: x = 0 or x = 63Therefore, the solutions for x are 0 and 63.
A pond initially contains 1000000 gal of water and unknown amount of an undesirable chemical. water containing 0.01 g of his chemical per gallon flows into the pond at a rate of 300 gal/h.the mixture flows out at the same rate ,so the amount of water in the pond remains constant .Assume that the chemical is uniformly distributed throughout the pond .How much of the chemical will be in the pond after a very long time ?
Final answer:
To calculate the amount of chemical in the pond after a very long time, multiply the rate at which the chemical flows in per hour by the number of hours that have passed.
Explanation:
To find out how much of the chemical will be in the pond after a very long time, we can first calculate the amount of chemical that flows into the pond per hour. Since 0.01 g of chemical flows in per gallon, and the rate of flow is 300 gallons per hour, the amount of chemical added per hour is 0.01 g/gal * 300 gal/hr = 3 g/hr.
Since the amount of water in the pond remains constant, the concentration of the chemical will also remain constant. Therefore, after a very long time, the amount of chemical in the pond will be the amount added per hour multiplied by the number of hours that have passed. So, if time is represented by 't', then the amount of chemical in the pond after a very long time is given by 3 g/hr * t.

Alan bought two bikes. He sold one to Beth for $300 taking a 25% loss. He also sold one to Greta for $300 making a 25% profit. Did Alan break even? If not, did he have a profit or loss and by how much?
No Alan did not break even
Alan incured a loss of 6.25 %
Solution:
Given that,
Alan bought two bikes
He sold one to Beth for $300 taking a 25% loss
He also sold one to Greta for $300 making a 25% profit
When a person sells two similar items, one at a gain of say x%, and the other at a loss of x%, then the seller always incurs a loss
Which is given as:
[tex]loss\ \% = (\frac{x}{10})^2[/tex]
Here, x = 25
[tex]loss\ \% = (\frac{25}{10})^2\\\\loss\ \% = 2.5^2\\\\loss\ \% = 6.25[/tex]

What are the angle measures of triangle ABC?
mA= 30°, m ZB = 60°, m 2C = 90°
mZA= 90°, m ZB = 60°, m 2C = 30°
mZA= 60°, m ZB = 90°, m2C = 30°
mZA= 90°, m ZB = 30°, m2C = 60°
∠A = 90°, ∠B = 60° and ∠C = 30°
Step-by-step explanation:
Step 1: Find whether the triangle is a right angled triangle by using Pythagoras theorem. Given sides are a = 24 (opposite to ∠A), b = 12√3 (opposite to ∠B) and c = 12 (opposite to ∠C).⇒ 12² + (12√3)² = 144 + 432 = 576
⇒ √576 = 24 = a. This shows that the triangle is a right angled triangle.
So ∠A = 90°
Step 2: Use trigonometric equations to determine the other angles.⇒ cos B = AB/BC = 12/24 = 1/2
⇒ ∠B = 60°
Step 3: The sum of the angles in a triangle is 180°. To find ∠C,⇒ ∠C = 180° - (90° + 60°) = 180° - 150°
⇒ ∠C = 30°
The angle measures of triangle ABC is therefore;
mZA= 90°, m ZB = 60°, m ZC = 30°
Angle measures of Right trianglesBy testing for Pythagoras triple;
24² = 12² + (12√3)²576 = 144 + 432576 = 576.Hence, the triangle is a right-angled triangle.
We can then evaluate mZC as follows;

same mhethod for:(1, 2)
The solutions are B) (0, 6) and (1, 2).
To find the solutions to the given system of equations:
y = x² − 5x + 6 and y = −4x + 6, we need to set the equations equal to each other and solve for x:
Set x² − 5x + 6 equal to −4x + 6:
x² − 5x + 6 = −4x + 6
Rearrange the equation to get:
x² − x = 0
Factor the equation:
x(x − 1) = 0
Solve for x:
x = 0 or x = 1
Substitute these values back into either original equation to find y:
When x = 0: y = −4(0) + 6 = 6 (so one solution is (0, 6)).
When x = 1: y = −4(1) + 6 = 2 (so another solution is (1, 2)).
Therefore, the solutions to the system of equations are B) (0, 6) and (1, 2)
