Which is a solution to the equation |10-5y| = 20

Answer:

a = 61

Step-by-step explanation:

Isolate the variable a by adding 40 to each side.

a = 21 + 40

a = 61

Answer:

A meter is 100 times larger than a centimeter

Step-by-step explanation:

A meter is larger than a cm. u can try it on a ruler. look  at the cm notice how it is smaller than a meter.

Answer:

It depends.

Step-by-step explanation:

I won't say centimeter is less or more than a meter, because 1 meter is equal to 100 center centimeter. But when you compare different measurement it can, for example:

2 m = 200 cm (Both are same)

3 m > 250 cm (m is greater, actually 3m = 300 cm)

4 m < 450 cm (cm is greater, 4 m = 400 cm)

The sum its +2

2+2=4

4+2=6

6+2=8

8+2=10

And so on the numbers just keep sum for 2

Final answer:

To find the sum of even numbers from 2 to 70, we use the arithmetic sequence sum formula, resulting in a total sum of 1260.

Explanation:

The student's question is asking to find the sum of even numbers from 2 to 70. To do this, we can recognize that this is an arithmetic sequence, where the first term (a1) is 2, the last term (an) is 70, and the common difference (d) is 2, as we are stepping through even numbers only. This sequence has (70/2) terms, which gives us 35 terms.

The sum of an arithmetic sequence is given by the formula S = n/2 (a1 + an), where S is the sum, n is the number of terms, a1 is the first term, and an is the last term. By applying this formula, we can calculate the sum as follows: S = 35/2 (2 + 70) = 35 (72/2) = 35 (36) = 1260.

Therefore, the sum of the even numbers from 2 to 70 is 1260.

Answer:

13.7

Step-by-step explanation:

Rewrite 15 - 1.3 as 15.0 - 1.3.

Then rewrite this result as

15.0

-  1.3

--------

and subtract as indicated.

First note that 15-1 = 14, and that 15-2= 13.  Thus, the correct answer will be between 13 and 14.

Subtract:

15.0

-  1.3

--------

This results in 13.7.

15 - 1.3 simplifies to 13.7 is the numeric result obtained after subtracting 1.3 from 15.

When we simplify the expression 15 - 1.3, we are performing basic arithmetic operations, specifically subtraction.

The step-by-step process is:

1. Write down the expression: 15 - 1.3

2. Perform the subtraction: Subtract 1.3 from 15

15 - 1.3 = 13.7

The result 13.7 is the difference between 15 and 1.3.

Answer:

Yes, it is a solution

Step-by-step explanation:

Plug the given (x, y) point of (1.5, 0) into the equation to find out...

4(0) + 2(1.5) = 3

0 + 3 = 3

3 = 3

The given ordered pair (1.5,0) is a solution of the equation 4y + 2x = 3.

The solution of an equation, when substituted makes the left-hand side equal to the right-hand side. It is the value for which the LHS = RHS.

The equation is 4y + 2x = 3.

The given ordered pair is (x,y) = (1.5,0). Now substitute the values of x and y.

4y + 2x = 3

⇒ 4(0) + 2(1.5) = 3

⇒ 0 + 3 = 3

⇒ 3 = 3

Therefore, we have determined that the given ordered pair (1.5,0) is a solution of the equation 4y + 2x = 3.

Answer:

-1/6 u + 2/3 = v

Step-by-step explanation:

You can solve for v here so that the equation is in terms of u.

-3u + 6 = 18v - 6                Add 6 to both sides

-3u + 12 = 18v                    Divide everything by 18

-3/18 u + 12/18 = v             Simplify fractions

-1/6 u + 2/3 = v

Example

If b = 5 and h = 10

a = 1/2 * b * h

a = 1/2 * 5 * 10

a = 25

2a = 2 (1/2 * b * h)

2 * 25 = 2 (1/2 * 5 * 10)

50 = 2 (25)

50 = 50

2a = b * h

2 * 25 = 5 * 10

50 = 50

2a - b = h

2 * 25 - 5 = 10

50 - 5 = 12

45 = 10

This is false.

If Hiro divided both sides by 2 instead:

2a ÷ 2 = b * h ÷ 2

2 * 25 ÷ 2 = 5 * 10 ÷ 2

50 ÷ 2 = 50 ÷ 2

25 = 25

Answer:

Hiro should divide both sides by 2.

Answer:

"Multiply the previous value by 2"

Step-by-step explanation:

Let's check the first 2 terms for all the answer choices.

1. Add [tex]\frac{1}{16}[/tex] to the previous value:

[tex]\frac{1}{32}+\frac{1}{16}=\frac{3}{32}[/tex]

Doesn't match.

2. Subtract [tex]\frac{1}{16}[/tex] from the previous value:

[tex]\frac{1}{32}-\frac{1}{16}=-\frac{1}{32}[/tex]

Doesn't match.

3. Divide the previous value by 2:

[tex]\frac{\frac{1}{32}}{2}\\=\frac{1}{32}*\frac{1}{2}=\frac{1}{64}[/tex]

Doesn't match.

4. Multiply the previous value by 2:

[tex]\frac{1}{32}*2=\frac{2}{32}=\frac{1}{16}[/tex]

DOES WORK!

Also, doing the same thing with all the other values would give us matching answer. So this choice is right.

Answer:

A) 25 • 64

B) 25/100 • 64

C) .25 • 64

D) 64 divided by 25/100

E) 25 divided by 64/100

B and C i believe

The values that have the same value as 25% of 64 are Options B) 25/100 · 64 and C) .25 · 64, both yielding the correct value of 16 when calculated.

To find the same value as 25% of 64, we need to express 25% in different formats and apply it to 64. Option B) 25/100 · 64 translates the percent into a fraction, then multiplies by 64. Option C) .25 · 64 converts the percentage directly into a decimal, again multiplying by 64. Both expressions will yield the same result, which is the value of 25% of 64.

Options A), D), and E) do not give the correct value. A) is simply multiplication without considering the percentage, D) is incorrect because dividing 64 by a fraction is equivalent to multiplying by its reciprocal, and E) is an incorrect fraction division that does not represent 25% of 64.

Therefore, the correct answers are B) and C).

Among the given options, option C) 2/3 is a possible probability for event Q that is greater than 1/2. Therefore, the correct answer is C) 2/3.

If event Q is more likely to occur than event T and the probability of event T is 1/2, then a possible probability of event Q could be any value greater than 1/2.

Let's dive deeper into the concept of probability and explore why option C) 2/3 is a possible probability for event Q.

When we say that event Q is more likely to occur than event T, it means that the probability of event Q is greater than the probability of event T. In this case, we are given that the probability of event T is 1/2.

To find a possible probability for event Q, select a value greater than 1/2. Option C) 2/3 fits this criterion. It indicates that event Q has a probability of 2/3, which is greater than 1/2.

Complete question

Event Q is more likely to occur than Event T. If P(Event T) = 1/2, what is a possible probability of Event Q? A)1/4 B)1/2 C)2/3 D)It cannot be determined.

The possible probability of event q is  is  [tex]\(\frac{3}{4}\).[/tex]

Since event Q is more likely than event T, the probability of event Q must be greater than the probability of event T.

The probability of event T is [tex]\(\frac{1}{2}\),[/tex] so the probability of event Q must be greater than [tex]\(\frac{1}{2}\).[/tex]

This satisfies the condition that event Q is more likely than event T because [tex]\(\frac{3}{4}\) (or 0.75)[/tex] is greater than [tex]\(\frac{1}{2}\) (or 0.5).[/tex]

 It is important to note that there are infinitely many probabilities that are greater than [tex]\(\frac{1}{2}\)[/tex] and less than or equal to 1 (the maximum probability for any event).

However, the question asks for a possible probability, and [tex]\(\frac{3}{4}\) is[/tex] a valid example that meets the given criteria.

The length of the missing side is 12.

The length of the missing side of the triangle can be calculated using pythagoras rule ;

Adjacent² = hypotenus² - opposite²

Substituting our values ;

a² = 37² - 35²

a² = 1369 - 1225

a² = 144

Take the square root of both sides ;

a = √144

a = 12

Hence, the length of the missing side is 12.

Basd on the right-angled triangle, the length of the missing side is equal to 12 units.

In Mathematics and Euclidean Geometry, Pythagorean theorem can be represented by the following mathematical equation (formula):

[tex]z^2=x^2 + y^2[/tex]

Where:

x is the opposite side of a right-angled triangle.

y is the adjacent side of a right-angled triangle.

z is the hypotenuse of a right-angled triangle.

Note: Let the variable "x" represent the missing side length.

In order to determine the missing side length, we would have to apply Pythagorean's theorem as follows;

[tex]37^2=x^{2} +35^2\\\\x^2=37^2-35^2\\\\x^{2} =1369-1225\\\\x^{2} =144\\\\x=\sqrt{144}[/tex]

x = 12 units.

$3098.93

Step-by-step explanation:

We can use the formula for compound growth to solve this. The formula is:

[tex]F=P(1+r)^t[/tex]

Where

F is the future value (the value at end of 14 years, our answer)

P is the initial amount invested ($1250)

r is the interest rate, in decimal (6.7% is 0.067)

t is the time in years (14, in our case)

Plugging in all the information we have:

[tex]F=P(1+r)^t\\F=1250(1+0.067)^14\\F=1250(1.067)^14\\F=3098.93[/tex]

The account will accrue $3098.93 after 14 years.
