what is 10 times as much as 50

Answers

ten times as much as fifty, or 10 * 50, is equal to 500

Final answer:

To find what is 10 times as much as 50, you multiply 50 by 10, which results in 500. This is a basic multiplication problem where the number 50 is increased by one order of magnitude.

Explanation:

The question 'what is 10 times as much as 50' involves a basic arithmetic operation known as multiplication. Multiplying a number by 10 is the same as adding a zero to the end of that number, when dealing with base ten numerical system. In this scenario, we are seeking to calculate 10 times 50, which can be expressed mathematically as:

Identify the two numbers involved in the multiplication: 10 (the multiplier) and 50 (the multiplicand).

Multiply the multiplicand by the multiplier: 50 × 10 = 500.

Therefore, 10 times as much as 50 is 500. This is consistent with the idea that a change from a power of ten to the next higher power means a ten-fold increase in value, or an increase by one order of magnitude.

5t+16=6-5t
I need help solving step by step

Answers

Equation: 5t+16=6-5t

Add 5t to both sides: 10t+16=6

Subtract 16 from both sides: 10t=-10

Divide by 10 from both side: t=-1

The solution of expression is,

t = - 1

We have to given that,

An expression to solve,

5t + 16 = 6 - 5t

Now, We can simplify as,

5t + 16 = 6 - 5t

Add 5t both side,

5t + 5t + 16 = 6 - 5t + 5t

10t + 16 = 6

Subtract 16 both side,

10t + 16 - 16 = 6 - 16

10t = - 10

Divide both side by 10,

t = - 10/10

t= - 1

Therefore, The solution is, t = - 1

Dawn raises money for her school in a jog-a-thon. She will get three dollars for every lap she completes. If it takes 4 laps to jog 1 mile, and Dawn jogs a total of 11 miles, how much money will Dawn raise for her school?

Answers

If Dawn gets 3$ for every lap she completes and 1 mile is 4 laps, and it says she runs 11 miles you would do 4 multiplied by 3, which is 12, once you get that answer you would multiply 12 by 11 and your answer would be: 132$
To check your answer you could do 4x11 which is 44 and you could multiply that by 3 which will also get you: 132$
She will raise 132 dollars.

A class is playing a game called “Guess my Number,” in which the number is an integer. The teacher gives these clues for the unknown number. 4 + h ≤ 7 and h + 1 > 3 What is the value of the unknown number, h?

Answers

3

If you subtract for 4 from 7 in the first expression, then h is less than or equal to 3.

If you subtract 1 from 3 in the second expression then h is greater than 2.

Thus the only value of h possible is 3.

Answer:

the answer is 3

if you subtract for 4 from 7 in the first expression, then h is less than or equal to 3.

If you subtract 1 from 3 in the second expression then h is greater than 2.

thus the only value of h possible is 3.

One eighth of a number is less than or equal to 3 what is the inequality

Answers

we will assume that the number is n
one eighth of the number = 1/8 x n = n/8
we know that this result n/8) is less than or equal (<=) 3
therefore, the inequality is:
n/8 <= 3
Final answer:

The inequality that represents the scenario given, where one eighth of a number is less than or equal to 3, is X ≤ 24.

Explanation:

The problem given can be represented by an inequality. We are told that one eighth of a number is less than or equal to 3. We can express this in equation form as X/8≤3, where X is the unknown number we are trying to figure out.

To solve for X, we can perform the inverse operation of division on both sides of the inequality by multiplying by 8, following the principle of maintaining balance within an inequality. The inequality thus simplifies to X ≤ 24.

The second of two numbers is 5 more than twice the first. Their sum is 80. Find the numbers.....Thanms

Answers

This is a simple equation; "x" is the first number and (5+2x) is the second number because it is "5 more than twice the first" and the sum = 80. So... x + (5+2x) = 80 You start by subtracting "x" and moving it to the other side...5 + 2x = 80 - x Then you add the "x" to the other side...5 + 3x = 80 Next, subtract 5 to the other side...3x = 75 Finally, divide the 3 to the other side...x = 75/3...x = 25 25 is the first number so you then multiply it by 2 and add five to get the final answer. 25 + 55 = 80

Factor expression 42x+49

Answers

Final answer:

To factor the expression 42x+49, we find the GCF which is 7, and express the expression as 7(6x + 7).

Explanation:

The question focuses on the task to factor the expression 42x+49. Factoring is a mathematical process in which we express a number or an algebraic expression as the product of its factors, which are usually simpler or more basic expressions.

To factor the given expression, we look for the greatest common factor (GCF) that both terms share. In this case, the GCF of 42x and 49 is 7. We factor the 7 out:

42x + 49 = 7(6x + 7)

The factored form is 7(6x + 7), which is the simplest form of the expression where 7 is a common factor multiplied by the binomial 6x+7.

Greg had a rope one meter long. Greg and his friend Brad each cut off 0.2 meter of the rope to use in Greg's tree house. Greg cut off another 1/10 meter of the rope to use on a chair. What is the length of the rope in meters, that was left unused?

Answers

0.5 meters Let's look at the problem and create an equation expressing it. "Greg had a rope one meter long" L = 1m "Greg and his friend Brad each cut off 0.2 meter of the rope to use in Greg's tree house." L = 1m - 0.2m - 0.2m "Greg cut off another 1/10 meter of the rope to use on a chair. " L = 1m - 0.2m - 0.2m - (1/10)m Now solve for L L = 1m - 0.2m - 0.2m - (1/10)m L = 1m - 0.2m - 0.2m - 0.1m L = 0.8m - 0.2m - 0.1m L = 0.6m - 0.1m L = 0.5m So the amount of rope left unused is 0.5 meters

find the measure of an angle whose supplement measures seventeen times its measure

Answers

supplement angles, sum = 180
lets x =  angle
its supplement = 180 - x

x + 17x = 180
18x = 180
x = 10
180 -10 = 170

answer
angle = 10
its supplement  = 170

Final answer:

The measure of an angle whose supplement is seventeen times larger than the angle itself is 10 degrees.

Explanation:

We are looking to find the measure of an angle that is said to have its supplement measure seventeen times larger than the angle itself. In terms of mathematical relationships, this means that if we call the angle in question x, then its supplement would be 17x. We know that supplementary angles add up to 180 degrees, hence we can write the equation x + 17x = 180. By solving this equation, we find that 18x = 180, and therefore x = 180÷18 which simplifies to x = 10. So the measure of the angle we are looking for is 10 degrees.

how do you solve -2(5+6x)+16=-90

Answers

Hi there,

-2(5 + 6x) + 16 = -90
-10 - 12x + 16 = -90
6 - 12x = -90
- 12x = -90 - 6
-12x = -96

Hence, X = 8

Hope this helps :)
first, distribute negative two to 5 and 6x. you should then have -10 • (-12x) + 16 =-90
after you get that follow order of operations. 120x + 16 = -90. next subtract 16 from both sides of the equation. 120x = -106.

A measurement unit is a standard quality used to express a physical quantity.

Given that;

To check the relation between 96 oz and 5 lb.

And, Value of 6 yards in feet.

Since, 1 lb = 16 oz

Hence, 5 lb = 5 x 16 = 80 oz

So, 96 oz > 80 oz

Thus, 96 oz > 5 lb

And,

Since, 1 yards = 3 feet

Thus, 6 yards + 1 feet = 6 x 3 + 1

                                 = 18 + 1

                                 = 19 feet.

L1 and L2 are parallel lines
the equation of L1 is y= 3x + 2
L2 passes through the point (3,4)
find an equation for L2

Answers

y = 3x + 2. The slope here is 3. A parallel line will have the same slope.

y = mx + b
slope(m) = 3
(3,4)...x = 3 and y = 4
now we sub and find b, the y int
4 = 3(3) + b
4 = 9 + b
4 - 9 = b
-5 = b

so ur other line, L2 is : y = 3x - 5 <==
The slope for 2 parallel lines is always the same so the slope will remain 3.(m=3)
To find the y intercept you have to replace the y and x with the 2 points given and the m with the slope and simplify.
so, y=mx+b
(4)=(3)(4)+b
4=12 +b
8=b
then plug in the intercept and the slope into the slope intercept equation and there is your answer.
y=3x+8

Every time, you add the amount of the previous number added. 
So, 

7 + 3 = 10
10 + 3(2) = 16
16 + 6(2) = 28
28 + 12(2) = 52
52 + 24(2) = 100

So the next number in the sequence is 100. 
Hope I helped!!

The next term is the given sequence is 100.

The given number sequence is 7, 10, 16, 28, 52,......

In the given sequence, pattern is as follows

7 + 3(1) = 10

10 + 3(2) = 16
