Answer:
To solve this equation, you can use cross multiplication to eliminate the fractional terms. Doing so gives you 11 * 17 = 13 * x. Solving for x gives you x = (11 * 17)/13. Dividing these two numbers gives you approximately x = 8.46. Rounding this number to the nearest tenth gives you x = 8.5. Therefore, the value of x that makes the equation true is approximately 8.5.

Johnny and his father go fishing at 5:00 AM. After motoring 6 km upstream, Johnny writes a letter to his friend, puts the letter in a bottle and drops it into the river. the bottle floats in the current and reaches at 7 : 40 AM the point where Johnny and his father began the trip. If the speed of the boat in still water is 9 km/h, what is the speed of the river current?
Answer:
4.5
Step-by-step explanation:
Probably too late for your RSM homework, but here is the solution:
6/(9-x) [Time they motored upstream] +6/x [Time it took the bottle to get back to the starting point] = 8/3 [Total Time]
Simplify to 54/(x(9-x))=8/3
Cross multiply: 162=(8x)(9-x)
Simplify -x^2+9x=20.25
Multiply both sides by negative one and move 20.25 to the other side. x^2-9x+20.25=0

Find the maturity value of a loan of $17104 after 4 months. The loan carries a simple interest rate of 12.5% peryear: Round to the nearest cent.O A. $17,639 50O B. $17.822.66OC. $17.816.67OD. $17.994.83
Answer: maturity value = $17816.67
Explanation:
The formula for calculating simple interest is expressed as
I = PRT
where
I is the interest
P is the principal or initial amount
R is the interest rate
T is the time in years
From the information given,
P = 17104
R = 12.5% = 12.5/100 = 0.125
We would convert 4 months to years. Recall
12 months = 1 year
4 months = 4/12 = 1/3
Thus, the interest is calculated as follows
I = 17104 x 0.125 x 1/3 = 712.67
maturity value = principal + interest
maturity value = 17104 + 712.67
maturity value = $17816.67

Step-by-step explanation:
1/2 of 12=1/4 of?
1/3 of 90=2/3of?
Answer:
24 and 45
Step-by-step explanation:
Okay, now that I can answer this question with the right answers:
The easy way to do this is to first solve the left hand side of the equation.
1/2 of 12 is the same as 12/2 = 6.
So 6 = 1/4 * x
To solve for that unknown x, just multiply both sides by 4 to cancel out the fraction:
6*4 = 4* 1/4*x
24 = x
For the other equation, do the same thing:
1/3 * 90 = 90/3 = 30
30 = 2/3*x
30*3 = 3* 2/3 *x
90 = 2x
90/2 = 2x/2
45 = x
A total of $9000 is invested: part at 6% and the remainder at 10%. How much is invested at each rate if the annual interest is $790?
I know the 6% is 396 I need to know the 10%
6% of a + 10% of (9000 - a) = 790
a = 2750
(9000 - a) = 6250
The amount invested at 6% is 2750.
The amount invested at 10% is 6250.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total amount = $9000
Let the part invested for 6% = a
Let the part invested for 10% = (9000 - a)
Now,
6% of a + 10% of (9000 - a) = 790
6% = 6/100 = 0.06
10% = 0.1
0.06a + 0.1(9000 - a) = 790
0.06a + 900 - 0.1a = 790
-0.04a = 790 - 900
0.04a = 110
a = 110/0.04
a = 2750
Now,
9000 - a = 9000 - 2750 = 6250
Thus,
The amount invested at 6% is 2750.
The amount invested at 10% is 6250.

What is the volume of the composite figure?
A complex figure comprised of 2 rectangular prisms. Prism A has a length of 7 inches, a width of 3 inches, and a height of 2 inches. Prism B has a length of 3 inches, width of 3 inches, and height of 7 inches.
69 in.3
105 in.3
276 in.3
4,536 in.3
Therefore, the volume of the composite figure is 105 cubic inches.
What is volume?In physics and mathematics, volume refers to the amount of space occupied by a three-dimensional object or region. It is a measure of the size of an object in three dimensions, and is typically expressed in cubic units, such as cubic meters, cubic feet, or cubic centimeters. The volume of an object can be calculated using a formula that is specific to the shape of the object. For example, the volume of a cube can be calculated by multiplying the length, width, and height of the cube, while the volume of a sphere can be calculated using the formula 4/3 x π x r^3, where r is the radius of the sphere. The concept of volume is important in many fields, including architecture, engineering, and science, as it is used to calculate the amount of space that an object or substance occupies, and to determine quantities such as mass and density.
Here,
To find the volume of the composite figure, we need to find the volume of each rectangular prism and add them together.
The volume of a rectangular prism is given by the formula V = l*w*h, where l is the length, w is the width, and h is the height.
For Prism A, V = (7)(3)(2) = 42 cubic inches.
For Prism B, V = (3)(3)(7) = 63 cubic inches.
The total volume of the composite figure is the sum of the volumes of the two prisms:
V_total = V_A + V_B
= 42 + 63
= 105 cubic inches

Work Shown:
The green triangle in the back has height 2.6 and an unknown base x. Half of this is x/2, which I'll call y. So y = x/2.
The green triangle in the back is split along the vertical dotted line to get two right triangles. The base of each right triangle is y = x/2.
Use the Pythagorean theorem to find y. Use that to find x
a^2+b^2 = c^2
y^2+(2.6)^2 = (3.2)^2
y^2 + 6.76 = 10.24
y^2 = 10.24 - 6.76
y^2 = 3.48
y = sqrt(3.48) .... apply square root
y = 1.8654758 approximately
x/2 = 1.8654758
x = 2*1.8654758
x = 3.7309516 also approximate
The base of the triangle is roughly 3.7309516 meters
We can now find the area of one green triangle
area of triangle = base*height/2 = 3.7309516*2.6/2 = 4.85023708
two triangles have approximate area 2*(4.85023708) = 9.70047416
----------------------------------
So far we've only considered the triangular faces. There are 3 more faces which are the rectangular sides. These are known as the lateral sides.
One way to get the lateral surface area is to multiply the perimeter of the triangle by the depth of the prism
perimeter of triangle = (side1)+(side2)+(side3)
perimeter = 3.7309516 + 3.2 + 3.2
perimeter = 10.1309516
lateral surface area = (depth)*(perimeter)
lateral surface area = (8.26)*(10.1309516)
lateral surface area = 83.681660216
----------------------------------
The last step is to add this lateral surface area onto the area of the two triangles to get the full surface area
surface area = (triangular area) + (lateral surface area)
surface area = (9.70047416) + (83.681660216)
surface area = 93.382134376
surface area = 93.382 square cm
