c) both statements together are sufficient, but neither statement alone is sufficient.

According to the question

The query asks if statements (1) and (2) by themselves are sufficient to determine whether x is an even number. The answer is that neither assertion by itself is adequate to ascertain what x is worth. However, when both claims are taken into account, they are adequate to decide whether or not x is an even number. This is due to the fact that if xyz is even and yz is odd, x must be even. If x were odd, both xy xz and y xz would be strange as well. Due to this, the proper response is "c) neither statement is adequate when read alone, but both assertions taken together are sufficient."

0.3 pounds of oranges are left and this can be calculated by following steps :

Convert the 8 2/5 oranges to pounds.

8 2/5 oranges = 8.4 oranges

1 orange = 0.5 pounds

8.4 oranges x 0.5 pounds = 4.2 pounds

Subtract the amount of oranges eaten (4 5/8 pounds) from the total amount of oranges (4.2 pounds).

4.2 pounds - 4 5/8 pounds = 0.3 pounds

Answer: 0.3 pounds of oranges are left.

By using the combination theorem, it can be concluded that the value of m + n = 125

Combination is the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed.

nCr = n! / (n - r)! r!

Let's denote the number of rectangles as r, and the number of squares as s:

r = ⁹C₂ x ⁹C₂

 = (9! / (9 - 2)! 2!) x (9! / (9 - 2)! 2!)

 = (9! / 7! 2!)   x   (9! / 7! 2!)

 = 36 x 36

 = 1296 rectangles

s = 1² + 2² + 3² + 4² + 5² + 6² + 7² + 8²

  = 1 + 4 + 9 + 16 + 25 + 36 + 49 + 64

  = 204 squares

Then we get the ratio of s : r as follows:

s / r = 204 / 1296

      = 17 / 108

Since m represents the horizontal lines and n represents the vertical lines, then m + n = 17 + 108 = 125.

Thus, it can be concluded that the value of m + n = 125

Answer:

Your answer is 9x^6*y^2π

Step-by-step explanation:

The formula for a circle is πr^2, with r as the radius.

Since 3x^3*y is the radius, you put that value in to get the equation:

(3x^3*y)^2*π

Once simplified, you get 9x^6*y^2π.

You can simplify further using the value of π, but it depends if the questions wants you to or not, mostly it doesn't.

The digit 8 has a value that is 1/10 times as great as the digit 8 in the number 2,980.7 will be 548

The 8 in our number, 2,980.7, is in the tens place and hence represents an 80.

The value of the digit 8 is equal to 1/10 of 10 divided by 1, which is 10 times greater than the value of the digit 888.

We need a number that contains an 8 and has a value that is 1/10 of the previous number, hence we need:

1/10*80 = 8

So the graph isn't linear because the graph shows a parabola (a boomerang kind of shape that happens if you use an exponent somewhere in a y=mx+b formula if I remember correctly) and not a straight line. Linear graphs cannot curve, and this one does. Not sure why it it would be a function though. Assuming the answer chosen is correct, my best guess as to why it might be a function is because it continues to go in the same direction forever, there is a predictable amount of change between each point and you can follow a formula to find every point on the graph.

Step-by-step explanation:

The last temperature will be 73.2 degrees Fahrenheit.

The parameter f(m) 15.2m+58 in the straight capability addresses the rate at which the water temperature increments over the long haul. In particular, it addresses the number of degrees Fahrenheit that the water temperature increments for each 1 moment of warming. So assuming the water has been warming for 2 minutes, its temperature will have expanded by 2 * 15.2 = 30.4 degrees Fahrenheit.

Parameter 58 in the linear function addresses the underlying temperature of the water when it begins warming. It is estimated in degrees Fahrenheit. So on the off chance that the water begins at a temperature of 58 degrees Fahrenheit and is warmed for 1 moment, its last temperature will be 15.2 + 58 = 73.2 degrees Fahrenheit.

Answer:

7/9 of the same money is 4900

Step-by-step explanation:

If 6/7 of a number is 5400, we can set up an equation to find the value of the number:

(6/7)x = 5400

To solve for x, we can multiply both sides by 7/6:

x = 5400 * (7/6)

x = 6000

Now that we know the number is 6000, we can find 7/9 of that value:

(7/9) * 6000 = 4900

So 7/9 of the same money is 4900.

The right triangle Short leg: 14 feet and  Long leg: 85 feet.

Because you have a right triangle,  and you know the hypotenuse, you can use the Pythagorean Theorem:

x2 + y2 = 852

You are told the difference between the 2 sides:

x = y + 71

Now you have 2 equations.  Use the expression for x in the 2nd equation, and substitute into the first:

(y + 71)2  + y2  = 852

Originally known as a rectangle triangle , a right triangle or right-angled triangle  is a triangle in which one angle is a right angle (that is, a 90-degree angle), i.e., It has two perpendicular sides.

The hypotenuse is the side that is opposite the right angle (side c in the figure). Legs are the sides that are close to the correct angle (or catheti, singular: cathetus).

Answer: it is A

Step-by-step explanation: just took the test

Answer:

1. T, W, E, G

2. C, B, D, A

Step-by-step explanation:

For question 1:

G passes through (2, 3) and (0, -1). So, the slope is [tex]\frac{-1-3}{0-2}[/tex] = 2.

T passes through (0, 3) and (4, 4) so the slope is (4-3)/(4-0) = [tex]\frac{1}{4}[/tex].

E has a slope of [tex]\frac{5}{3}[/tex] because the equation is y = mx+b where m is the slope.

W has a slope of  [tex]\frac{1}{3}[/tex]  since slope is increase in y divided by increase in x.

The order of these from least to greatest is [tex]\frac{1}{4}[/tex], [tex]\frac{1}{3}[/tex], [tex]\frac{5}{3}[/tex], and 2.

Therefore, the answer is T, W, E, G.

For question 2:

A passes through (0, -1) and (2, 2), so the slope is (2- -1)/(2-0) = [tex]\frac{3}{2}[/tex].

B passes through (2, 0) and (4, 1), so the slope is (1-0)/(4-2) = [tex]\frac{1}{2}[/tex].

C has a slope of [tex]\frac{1}{4}[/tex] since the equation is y=mx+b where m is the slope.

D has a slope of [tex]\frac{3}{4}[/tex] since the slope is increase in y divided by increase in x.

The order of these from least to greatest is [tex]\frac{1}{4}[/tex], [tex]\frac{1}{2}[/tex], [tex]\frac{3}{4}[/tex], and [tex]\frac{3}{2}[/tex].

Therefore, the answer is C, B, D, A.

What is an proportion?

A proportion is a mathematical equation that compares two ratios. It is usually written as two equal fractions or ratios, one on each side of the equation. A proportion can be used to compare the relationship between different quantities, such as measurements, rates, or even time.

We can use proportion to solve this problem. The proportion relates the map scale to the actual distance:

0.75 inch / 50 miles = x / distance

where x is the actual distance we want to find.

We can cross-multiply and solve for x:

0.75 inch * distance = 2.75 inches * 50 miles

x = (2.75 inches * 50 miles) / 0.75 inch

x = (137.5 miles)
