The temperature went up by 33° fahrenheit because -8+8=0 and 0+25= 25 so 8+25=33

10. Both x and y vary inversely with each other. When x is 10, y is 6,which of the following is not a possible pair of correspon

Answer:

D) 45 and 1.2

Step-by-step explanation:

The "varies inversely" relationship is described by the equation ...

y = k/x . . . . . . y varies inversely with x (and vice versa)

The value of k can be found from known values of x and y:

xy = k . . . . . . multiply the above equation by x

(10)(6) = k = 60 . . . . using the given values

__

To check if a given pair of numbers satisfies ...

y = 60/x

you can multiply them together to see if the product is 60.

(A) 12×5 = 60

(B) 15×4 = 60

(C) 25×2.4 = 60

(D) 45×1.2 = 54 . . . . . not a possible pair of corresponding values.

45 and 1.2 are not a possible solution for x and y.

What is represented by p v q?

Stella [2.4K]

$\lor$ is the logical or/disjunction symbol. $p\lor q$ means " $p$ or $q$ ". Disjunction is commutative, which means $p\lor q$ is equivalent to $q\lor p$ .

So if $p$ represents $x$ and $q$ represents $x>3$ , then $p\lor q\equiv q\lor p$ means $x>3$ or $x$ .

A parking lot has 916 parking spaces that are shaped like parallelograms. The base of each space is 10 feet, and the height of e

dmitriy555 [2]

The area of a parallelogram is $A=bh$

$A=10(18.5) \\ A=185$

I am assuming you're asking for the entire parking lot, so you would have to multiply the above area by 916

$185(916) = 169,460 ft^{2}$

So the answer is (D)

What are the possible lengths for x, the third side of a triangle, if two sides are 21 and 10

SashulF [63]

To solve we need to use Pythagoras theorem ( $a^{2} + b^{2} = c^{2}$ )

There are 2 possible lengths for x: hypotenuse or one of the 2 shorter sides.

Hypotenuse:
10^{2} + 21^2 = $x^{2}$
100+441= $x^{2}$
$\sqrt{541} = \sqrt{ x^{2} }$
23.3≈x

Shorter leg:
$10^2 + x^2=21^2$
$x^2= 21^2-10^2$
$x^{2}$ = 441-100
$\sqrt{ x^{2} } = \sqrt{341}$
x≈18.47
