Answer:
Step-by-step explanation:
continuing from the 3rd line....
10x - 1 = 10x + 8 (subtract 10x from both sides)
10x - 10x - 1 = 10x -10x + 8
-1 = + 8 (this last line is not part of the solution but i'm showing it here so you can see what is going on, obviously -1 cannot be 8)
Since -1 ≠ 8, the equation has no (i.e zero) solutions

What’s the volume of a cone with a radius of 3cm and a height of 4.5cm
Answers
Answer:
42.41
Step-by-step explanation:
V=π[tex]r^{2}[/tex][tex]\frac{h}{3}[/tex]=π * [tex]3^{2}[/tex] * ≈ 42.4115
The volume of a cone with a radius of 3cm and height of 4.5cm is approximately 42.41 cubic centimeters.
The volume (V) of a cone can be found using the formula: V = (1/3)πr²h, where r is the radius of the base and h is the height of the cone. To find the volume of a cone with a radius of 3cm and a height of 4.5cm, we substitute these values into the formula:
V = (1/3)π(3cm)²(4.5cm)
Calculating this further:
V = (1/3)π(9cm²)(4.5cm)
V = (1/3)π(40.5cm³)
V ≈ (1/3)(3.14159)(40.5cm³)
V = 42.41cm³
Therefore, the volume of the cone is approximately 42.41 cubic centimeters.

Mary Seitz invested a certain amount of money in a savings account paying 5% simple interest per year. When she withdrew her money at the end of 3 years, she received $300 in interest. How much money did Mary place in the savings account?
Mary Seitz invested $ blank in the savings account.
Answers
Answer:
Mary Seitz invested $ 2,000 in the savings account.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Interest rate = 5% simple = 0.05
Time of the investment = 3 years
Amount of interest = $ 300
2. How much money did Mary place in the savings account?
Let's recall the formula of the simple interest:
A = P * (1 + rt), where:
A = Final value of the investment
P = Initial investment
r = Interest rate
t = Time
Replacing with the values we know:
A = P * (1 + 0.05 * 3)
A = P * (1 + 0.15)
P + 300 = 1.15P (A = P + 300)
P - 1.15P = -300
-0.15P = -300
P = -300/-0.15
P = 2,000
Mary Seitz invested $ 2,000 in the savings account.

The number 44.4 is what percent of 74?
Answers
Answer:
60%
Step-by-step explanation:
[tex]percentage = \frac{44.4}{74} \times 100\% = 60\%[/tex]
Answer:
60%
Step-by-step explanation:
In questions like these, we take 74 to be the whole. As such, we express the whole as 100%. Then, we take 44.4 as just a portion of the whole. We therefore ask ourselves, what portion of the whole is 44.4.
We take 44.4 as the numerator and the whole, 74, as the denominator. We then express 44.4 as a fraction of the denominator. That is,
44.4/74
To express this as a percent, we multiply the above results by 100.
Thus, (44.4/74) x 100
= 60%

Change the denominator (the bottom number of the fraction) into something both can go into. 4 can go into 8 and 8 can go into 8. Rewrite the fractions beside the actual numbers. Example: /8 and /8 then remember, 4 goes into 8 two times. So do 1x2=2. Then remember 8 goes into 8 1 time so do 3x1=3. Add the two fractions 3/8+2/8= 5/8. Then add the whole numbers as well. 7+3+5/8= 10 5/8. I know that it's really confusing explaining it through words but if you ever need further explanation don't hesitate to ask! :)

The difference of two numbers is 2 the product of the two numbers is 440 what are the two numbers explain
Answers
Final answer:
To solve the student's question, we created a system of equations based on the given conditions, solved for the two numbers using algebraic methods, and verified that the numbers 22 and 20 have a difference of 2 and a product of 440.
Explanation:
The student has asked to find two numbers where their difference is 2 and their product is 440. This problem can be solved by establishing a system of equations and using algebraic methods to find the two numbers.
Let x be the larger number and y be the smaller number. According to the question, we have two equations:
x - y = 2
x × y = 440
From the first equation, y can be expressed as x - 2. Subsequently, by substituting y in the second equation, we get x(x - 2) = 440. Simplifying this yields a quadratic equation: x² - 2x - 440 = 0. Solving the quadratic equation gives us two possible values for x, which we can then use to find the corresponding values of y.
By factoring, we determine the two numbers that satisfy both conditions are 22 and 20. To verify this, we must ensure that the difference between these two numbers is 2 and their product is 440, which is indeed the case: 22 - 20 = 2 and 22 × 20 = 440.
you only have a 1/4 measuring cup and a recipe calls for 8 3/4 cups of flour how many 1/4 cups would you need to use?
Answers
Answer:
35 cups are needed.
Step-by-step explanation:
We have to divide 8 3/4 by 1/4.
Convert to improper fraction.
8 3/4 = [(8*4) + 3] / 4
= 35 / 4.
35/4 / 1/4
= 4*35 / 4
= 35 cups.
To measure out 8 3/4 cups of flour using a 1/4 measuring cup, you would need to use 35 1/4 cups.
Explanation:To determine how many 1/4 cups you would need to use, you can divide the total amount of flour required by the size of the measuring cup. In this case, the recipe calls for 8 3/4 cups of flour. So, you would divide 8 3/4 by 1/4.
When you divide a fraction by another fraction, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1/4 is 4/1, which is the same as 4. So, 8 3/4 ÷ 1/4 is equal to 8 3/4 * 4, which is 35.
Therefore, "you would need to use 35 1/4 cups to measure out 8 3/4 cups of flour".

Answers
Lisa's assertion that Josh has played twelve times as many soccer matches as her is false. In actuality, Josh has played three times as many matches as Lisa.
Explanation:In the scenario, Lisa claims that her brother Josh has played in 12 times as many soccer matches as she has. To verify this statement, we would have to multipy the number of matches Lisa played by 12. Hence, 6 (Lisa's matches) times 12 equals to 72 matches. However, we know from the question that Josh has only played 18 matches. Therefore, Lisa's statement is incorrect because, in reality, Josh has only played three times as many matches as Lisa (18 divided by 6 equals 3), not 12 times as many.

Lisa's statement is not correct because Josh has played in 3 times as many soccer matches as Lisa.
Explanation:
Lisa's statement is not correct because she says Josh has played in 12 times as many matches as she has, but this is not the case. To determine how many times more matches Josh has played compared to Lisa, we can calculate the ratio of Josh's matches to Lisa's matches.
Josh has played in 18 soccer matches and Lisa has played in 6 soccer matches. To find out how many times more matches Josh has played, we divide Josh's matches by Lisa's matches:
Josh's matches / Lisa's matches = 18 / 6 = 3
So, Josh has played in 3 times as many soccer matches as Lisa. Lisa's correct statement would be that Josh has played in 3 times as many matches as she has.

Eight increased by the product of a number and 5 is at most -28 (translate the sentence into an inequality)
Answers
Answer:
The inequality would be 8+5x[tex]\leq[/tex]-28
Step-by-step explanation:
The sentence says "8 increased", this is telling you that the inequality includes the number 8 that is being added to something else.
"Product of a number and 5", this tells you that there is a variable that is being multiplied by 5.
"at most -28" means that it is less than or equal to -28.
The sentence 'Eight increased by the product of a number and 5 is at most -28' is translated into the inequality 8 + 5x <= -28, which simplifies to x <= -7.2.
Explanation:The sentence "Eight increased by the product of a number and 5 is at most -28" can be translated into the following inequality:
Let x be the unknown number. Then the product of this number and 5 would be 5x. According to the sentence, if you increase eight by this product (which is 8 + 5x), the result should be 'at most -28'. In mathematical terms, 'at most' means less than or equal to. So, the inequality that represents this sentence is:
8 + 5x ≤ -28
To solve the inequality, subtract 8 from both sides:
5x ≤ -28 - 8
5x ≤ -36
Finally, divide both sides by 5 to isolate x:
x ≤ -36 / 5
x ≤ -7.2
This inequality means that x, the unknown number, must be less than or equal to -7.2.
