Answer: 14 minutes
Step-by-step explanation:
Because 28 ÷ 2 is 14.
We have to divide the number Bob has to draw by the number of minutes.
We multiply the number of minuted by 2.
Answer is 14
Answer:
14 minutes
Step-by-step explanation:
We can use ratios to solve
14 shapes 28 shapes
---------------- = ----------------
7 minutes x minutes
Using cross products
14x = 28*7
Divide each side by 14
14x/14 = 28*7/14
x = 14

Answer:
x = -10
Step-by-step explanation:
9 x -10 = -90
What is a possible step when solving for x? Select all that apply.
512x+23x=37
A. x = 37
B. x = 6
C. 37x = 6
D. 376x=37
E. 112x+23x=37
Using operations with fractions, it is found that the possible steps are:
B. [tex]x = 6[/tex].D. [tex]\frac{37x}{6} = 37[/tex]E. [tex]\frac{11}{2}x + \frac{2}{3}x = 37[/tex]The equation given is:
[tex]5\frac{1}{2}x + \frac{2}{3}x = 37[/tex]
The improper fraction can be written as:
[tex]5\frac{1}{2} = \frac{5\times 1 + 2}{2} = \frac{11}{2}[/tex]
Then:
[tex]\frac{11}{2}x + \frac{2}{3}x = 37[/tex]
Applying the least common multiple:
[tex]\frac{33x + 4x}{6} = 37[/tex]
[tex]\frac{37x}{6} = 37[/tex]
[tex]37x = 37 \times 6[/tex]
[tex]x = \frac{37 \times 6}{37}[/tex]
[tex]x = 6[/tex]
Hence, options B, D and E are correct.

Answer:
5 cups
Step-by-step explanation:
hi! to find the sum of the soup mix, we have to add all the fractions together.
7/4 + 1/2 + 5/3 + 1/3 +1/4 + 1/2
we have to find a common denominator for each, which is the LCM of the denominators. this would be 12. let's change the fractions so we can add them up.
21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12
add the numerators and keep the denominators the same.
(21+6+20+4+3+6)/12
60/12
this simplifies to 5.
the total amount of soup mix is 5 cups.
Answer:
5 cups of soup mix
Step-by-step explanation:
Make all the denominators equal. The lowest common denominator is 12 so multiple the denominators with 4 by 3, 2 by 6, and 3 by 4.
[tex]\frac{7}{4} *3=\frac{21}{12}[/tex]
[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]
[tex]\frac{5}{3} *4=\frac{20}{12}[/tex]
[tex]\frac{1}{3} *4=\frac{4}{12}[/tex]
[tex]\frac{1}{4} *3=\frac{3}{12}[/tex]
[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]
Now that all the fractions have the same denominator you can add them all together.
[tex]\frac{21}{12} +\frac{6}{12} +\frac{20}{12} +\frac{4}{12} +\frac{3}{12} +\frac{6}{12}=\frac{60}{12}[/tex]
Then simplify the fraction to find out how many total cups of soup mix you have.
[tex]\frac{60}{12} =5[/tex]
5 cups of soup mix
Find the accumulated value of an investment of $5,000 at 4.25% compounded monthly for 8 years. Round your answer
Answer:

A truckload of plastic soda bottles was finely shredded at a recycling center. The plastic shreds were placed into 55-liter drums. What it the mass of the plastic shreds inside one of the drums in kg? Assume lowest density within the range.
Answer:
75,900 g
Step-by-step explanation:
m=d×v
(1.38g/cm^3) × (55,000)
The mass of the drum is 75.9 kg.
What is the mass of the drum?The mass of the drum is the product of the volume and density of the drum.
What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that the plastic shreds were placed into 55-liter drums.
We have to determine the mass of the plastic shreds inside one of the drums in kg.
Here density of the drum = 1.38g/cm³ and the volume of the drum = 55,000
The mass of the drum = (1.38g/cm³) × (55,000)
The mass of the drum = 75,900 g
The mass of the drum = 75.9 kg

For each of these problems, remember SOH-CAH-TOA.
Sine = opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tangent = opposite/adjacent
5) Here we are looking for the cosine of the 30 degree angle. Cosine uses the adjacent side to the angle over the hypotenuse. Therefore, cos(30) = 43/50.
6) We have an unknown side length, of which is adjacent to 22 degrees, and the length of the hypotenuse. Since we know the adjacent side and the hypotenuse, we should use Cosine. Therefore, our equation to find the missing side length is cos(22) = x / 15.
7) When finding an angle, we always use the inverse of the trigonometry function we originally used. Therefore, if sin(A) = 12/15, then the inverse of that would be sin^-1 (12/15) = A.
8) We are again using an inverse trigonometry function here. We know the hypotenuse, as well as the side adjacent to the angle. Therefore, we should use the inverse cosine function. Using the inverse cosine function gives us cos^-1 (9/13) = 46 degrees.

The value of x which satisfies the equation (- 8) = 2x + 4 is ? 6. The solution of the equation 10 - (x + 2) = 7x is ? 7. A linear equation in one variable has _________ solution ? 8. The sum of the two consecutive multiples of 10 is 210. The smallest multiple is 9. Convert the statement "adding 15 to 4 times x is 39" into an equation 10. Value of "S" in 1/3 + S = 2/5 is ?
Answer:
Step-by-step explanation:
A linear equation is of the form ax+b and the highest degree of x is 1. You can see that from the power of x which is 1.
The power of x is zero from the equating. It is not reflecting because anything raise to power if zero gives 1
To get the solution of the equation ax+b = 0
We will make x the subject of the formula
ax = -b
Divide both side's by a
ax/a = -b/a
x = -b/a
If 2x-3 = 0
2x = 0+3
2x = 3
2x/2 = 3/2
x = 3/2
Given -8 = 2x+4
2x = -8-4
2x = -12
x = -12/2
x = -6
A linear equation in one variable is known to have ONE solution. This is as demonstrated in the equation above, we cans see that the only solution is -6(just one solution)
Convert the statement "adding 15 to 4 times x is 39" into an equation 1
The product of 4 and x is 4x
Adding 15 to 4x will give
15+4x
If the resulting expression is equal to 39, the final equation will be;
15+4x = 39
