The solution to 10m -28 = 6 -7m​ is m = 2.

Step-by-step explanation:

Given 10m - 28 = 6 - 7m ⇒ 10m + 7m = 6 + 28 ⇒ 17m = 34 ⇒m= 34/17

⇒ m = 2.

Answer: Last option.

Step-by-step explanation:

Given the expression:

[tex]\sqrt{\frac{128x^5y^6}{2x^7y^5}[/tex]

The Quotient of powers property states that:

[tex]\frac{a^m}{a^n}=a^{(m-n)}[/tex]

And the Power of a powet property states that:

[tex](a^m)^n=a^{mn}[/tex]

Then, applying these properties, you get:

[tex]=\sqrt{\frac{(2^3)^26y}{x^2}[/tex]

Now you must remember that:

[tex]\sqrt[a]{a^n}=a[/tex]

Therefore, simpliying the expression, you get:

[tex]=\frac{2^3\sqrt{y}}{x}=\frac{8\sqrt{y}}{x}[/tex]

Answer:

D. 8√y/x

Step-by-step explanation:

The equation that represents a line parallel to 3x + 5y = –3 is A. 3x + 5y = 2, as it only differs in the y-intercept from the original line, therefore having the same slope which ensures it's parallel.

To determine which equation represents a line parallel to the given line 3x + 5y = –3, we should know that parallel lines have the same slope. The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. Let's first rewrite the given equation in slope-intercept form.

3x + 5y = –3
5y = -3x - 3
y = -3/5x - 3/5

The slope of this line is -3/5. We now look for an equation among the options which has the same slope of -3/5.

A. 3x + 5y = 2 is the correct choice as it only differs in the y-intercept, which makes it parallel to the original.

B. 6x + 10y = –6 is actually equivalent to the original equation when divided by 2, hence it's the same line, not merely parallel.

C. –5x + 3y = 2 has a different slope.

D. –3x + 5y = –3 has a different slope.

Step-by-step explanation:

Vertical angles opposite each other when two lines cross.

"Vertical" refers to the vertex (where they cross), NOT up/down. They are equal.

Answer:

[tex]\angle EYL[/tex] and [tex]\angle AYS[/tex]

[tex]\angle SYL[/tex] and [tex]\angle EYA[/tex]

Step-by-step explanation:

Vertical angles can be defined as the pair of angle which are opposite when two lines crosses, as the image attached shows.

Now, [tex]\angle EYL[/tex] and [tex]\angle AYS[/tex] are vertical angles, because they are opposite when lines ES and AL cross at point Y.

Another pair of vertical angles are [tex]\angle SYL[/tex] and [tex]\angle EYA[/tex], because they are opposite when lines ES and AL cross at point Y.

Therefore, all pair of angles which are vertical angles are

[tex]\angle EYL[/tex] and [tex]\angle AYS[/tex]

[tex]\angle SYL[/tex] and [tex]\angle EYA[/tex]

Answer: 47/8

You're looking for an inequality of the form [tex]|t-b|\le a[/tex], or [tex]-a\le t-b\le a[/tex], or [tex]b-a\le t\le b+a[/tex].

Start with

[tex]350^\circ\le t\le400^\circ[/tex]

Notice that 375º is the midpoint of this interval of temperatures. If we subtract all sides by 375º, then we get

[tex]-25^\circ\le t-375^\circ\le25^\circ[/tex]

so we can set [tex]a=25^\circ[/tex] and [tex]b=375^\circ[/tex], and we can rewrite this inequality in terms of absolute values as

[tex]|t-375^\circ|\le25^\circ[/tex]

Answer:

After these reflections, the coordinates of P' will be P'(4,-4)

Step-by-step explanation:

The question is

After these reflections, the coordinates of P' will be?

we have

Triangle PQR, with coordinates P(-4, -4), Q(-1, -3), and R(-3, -1)

Part 1) Reflect triangle PQR across the x-axis

we know that

The rule of the reflection of a point across the x-axis is

(x,y) -----> (x,-y)

Applying the rule of the reflection across the x-axis at the coordinates of triangle PQR

P(-4, -4) -----> P'''(-4,4)

Q(-1, -3) -----> Q'''(-1, 3)

R(-3, -1) ----> R'''(-3, 1)

Part 2) Reflect triangle P'''Q'''R''' across the y-axis

we know that

The rule of the reflection of a point across the y-axis is

(x,y) -----> (-x,y)

Applying the rule of the reflection across the y-axis at the coordinates of triangle P'''Q'''R'''

P'''(-4,4) -----> P''(4,4)

Q'''(-1, 3) ---> Q''(1, 3)

R'''(-3, 1) ---> R''(3, 1)

Part 3) Reflect triangle P''Q''R'' across the x-axis again

we know that

The rule of the reflection of a point across the x-axis is

(x,y) -----> (x,-y)

Applying the rule of the reflection across the x-axis at the coordinates of triangle P''Q''R''

P''(4,4) ---->  P'(4,-4)

Q''(1, 3) ----> Q'(1, -3)

R''(3, 1) ----> R'(3, -1)

therefore

After these reflections, the coordinates of P' will be P'(4,-4)

Answer:

$58.50

Step-by-step explanation:

It is given that the the student council pays

For per french fry = $0.85

For per soda fry = $1.20

Discount on the combo of  fries and soda = $0.75

Total revenue for one combo = $0.85 + $1.20 - $0.75 = $1.30

Since the total revenue for one combo is $1.30, therefore the total revenue for 45 combo is

Total revenue for 45 combo = 45 × $1.30 = $58.50

Therefore, they will make $58.50 if they sell 45 combos.

Answer:

B. 86.3%

Step-by-step explanation:

The correct answer is C. 88.7%.

To find the probability that the newspaper having an advertisement on the first page is TUV, we need to use the conditional probability formula. The probability that an event A occurs given that event B has occurred is given by:

[tex]\[ P(A|B) = \frac{P(A \cap B)}{P(B)} \][/tex]

In this case, event A is that the newspaper is TUV, and event B is that the newspaper has an advertisement on the front page. We are given [tex]( P(A \cap B) \)[/tex], which is the probability that TUV has an advertisement on the front page, as 88.7%. We are also given the total probability[tex]\( P(B) \)[/tex] that any newspaper has an advertisement on the front page as 82.4%.

Using the conditional probability formula, we get:

[tex]\[ P(\text{TUV}|\text{Ad}) = \frac{P(\text{TUV} \cap \text{Ad})}{P(\text{Ad})} \][/tex]

[tex]\[ P(\text{TUV}|\text{Ad}) = \frac{88.7\%}{82.4\%} \][/tex]

Now, we calculate this probability:

[tex]\[ P(\text{TUV}|\text{Ad}) = \frac{88.7}{100} \times \frac{100}{82.4} \][/tex]

[tex]\[ P(\text{TUV}|\text{Ad}) = \frac{88.7}{82.4} \][/tex]

[tex]\[ P(\text{TUV}|\text{Ad}) \approx 1.0765 \][/tex]

However, probabilities cannot be greater than 1, so we must have made a mistake in our calculation. The correct approach is to realize that the total probability of 82.4% already includes the probability of TUV having an advertisement. Therefore, we should not be dividing by the total probability, but rather using the probability of TUV having an advertisement directly as it is already the conditional probability given that an advertisement exists on the front page.

Answer:

32 inches or [tex]2\dfrac{2}{3}[/tex] feet

Step-by-step explanation:

1 foot = 12 inches

2 feet = 24 inches

Initially, the hole was 2 feet deep, after 3 days, the hole sank 8 inches further, so after 3 days, the hole was 2 feet 8 inches deep.

2 feet 8 inches = 24 inches + 8 inches = 32 inches

Now,

1 inch [tex]=\dfrac{1}{12}[/tex] foot

Then

32 inches [tex]=\dfrac{32}{12}=\dfrac{8}{3}=2\dfrac{2}{3}[/tex] inches

Answer:

The system consists of parallel lines ⇒ 2nd answer

Both lines have the same slope ⇒ 3rd answer

Step-by-step explanation:

Lets revise the types of the solutions of the system of equations

Case 1:

→ If the two equations have the same coefficients of the two variables

   and different numerical terms then the two equations represented

   by two parallel lines

Ex: ax + by = c , ax + by = d

Case 2:

→ If the two equations have the same coefficients of the two variables

   and same numerical term then the two equations represented

   by the same line

Ex: ax + by = c , ax + by = c

Case 3:

→ If the two equations have different coefficients of one of the variables

   or the two variables then they represented by two intersected lines

   and the system has one solution

Ex: ax + by = c , dx + ey = f

The system of equation is

* y = [tex]\frac{1}{3}[/tex] x - 4

* 3 y - x = -7

Multiply the first equation by 3

∴ 3 y = x - 12

Subtract both sides by x

∴ 3 y - x = - 12 ⇒ (1)

∵ 3 y - x = - 7 ⇒ (2)

The system of equations has same x-coefficient and same y-coefficient

in both equations but the numerical terms are different, then they

represented by two parallel lines as first case above

and parallel lines have the same slope

The system consists of parallel lines

Both lines have the same slope

Answer:

2^(-n^2+n+1)

Step-by-step explanation:

2^(n+2)*2^(n-1)*2^(-n(n-1))=2^((n+2)+(n-1)-(n^2-n))=2^(-n^2+3n+1)

I can do it because they have the same base, so I can add the exponents.

I can write 4^n=2^2n. So I have 2^(-n^2+3n+1) / 2^2n and they have the same base again (2), so we can subtract the exponents.

2^((-n^2+3n+1)-2n)=2^(-n^2+n+1)

To solve, multiply 5 by 5 twenty-two times. It will equal 2384185791015625. Then, multiply 5 by 5 thirteen times. It will equal 1220703125. Finally, simplify 2384185791015625/1220703125. You should get 1953125 as your answer. Therefore, 1953125 is the answer.

Edit: 5^22 means 5²² which means to multiply 5 by 5 by 5... for 22 times. It means the exponents. (Power of)

The expression 5^22/5^13 simplifies to 5^(22-13) which equals 5^9. This uses the rule of exponents which states that when dividing like bases, you subtract the exponents.

To simplify the expression 5^22/5^13, we need to apply the exponent rule which states that when you divide two powers with the same base, you subtract the exponents. In this case, we subtract the exponent of 5^13 from the exponent of 5^22. So, 5^22/5^13 = 5^(22-13) = 5^9.

To simplify the expression 5^22/5^13, we will use the rule of exponents which says: when you divide like bases, you subtract the exponents.

Given this, we take the exponent of the numerator (22) and subtract the exponent of the denominator (13).

Therefore, 5^22/5^13 simplifies to 5^(22-13), which equals 5^9.

The area of polygon ABCD is found by dividing it into two rectangles and calculating their areas separately, which are then added together to get a total area of 77 square units.

Calculating the Area of Polygon ABCD:

The area of polygon ABCD with vertices at A(-4,2), B(3,2), C(3,-5), and D(-4,-2), we can split the polygon into two rectangles. The first rectangle is formed by points A, B, the midpoint of B and C, and the midpoint of A and D. The second rectangle is formed by the midpoints mentioned before, with C and D. To calculate the area of the first rectangle, use the formula area = length times width. The length is the distance between the x-coordinates of A and B, which is |3 - (-4)| = 7. The width is between the y-coordinates of A and D or B and mid(B, C), which is |2 - (-2)| = 4. Thus, the area of the first rectangle is 7 times 4 = 28 square units.

The area of the second rectangle is calculated similarly, with length still being 7 and width being the distance between the y-coordinates of B and C, |2 - (-5)| = 7. Therefore, the area of the second rectangle is 7 times 7 = 49 square units. Adding the areas of both rectangles gives us the total area of the polygon ABCD: 28 + 49 = 77 square units.
