A 160lb person has 4.6 quarts of blood what is the direct variation
zhenek [66]
So weight=x
blood=y

we got that when
y=kx
when y=4.6, then x=160
4.6=160k
divide both sides by 160
0.02875=k

the direct variation is
y=0.02875x

so plug in x and get y

the answers in (x,y) form is
(0,0)
(50,1.4375)
(75,2.15625)
(100,2.875)

6m-2(7+3m)>5(2m-3)-m
Tpy6a [65]

Answer:

Therefore the value is

m

Step-by-step explanation:

Given:

6m-2(7+3m)>5(2m-3)-m ....Given

Step 1. Applying Distributive Property A(B+C)=AB+AC we get

6m-2\times7-2\times 3m>5\times 2m-5\times 3-m

6m-14-6m>10m-15-m\\-14>9m-15

Step 2. Add 15 both the side

-14+15>9m-15+15\\1>9m

Step 3. Dividing both the side by 9

\dfrac{1}{9}>\dfrac{9m}{9}\\\\\dfrac{1}{9}>m

Therefore the value is

m

Given the function
jeka94

Answer:

<h2>The domain is all real numbers except</h2><h2>x = 3 and x = 7.</h2>

Step-by-step explanation:

We know that in a fraction the denominator must be different from 0.

Therefore:

f(x)=\dfrac{4x+17}{x^2-10x+21}\to\ D:x^2-10x+21\neq0\\\\x^2-7x-3x+21\neq0\\\\x(x-7)-3(x-7)\neq0\\\\(x-7)(x-3)\neq0\iff x-7\neq0\ \wedge\ x-3\neq0\\\\x-7\neq0\qquad\text{add 7 to both sides}\\x\neq7\\\\x-3\neq0\qquad\text{add 3 to both sides}\\x\neq3

Sloan [31]

Answer: 5¹⁵/₁₆

The Wildflower Trail is currently 2³/₈ miles long.

If the city will extend it by 2¹/₂ in 5 years, the length in five years will be;

= 2³/₈ * 2¹/₂

= 19/8 * 5/2

= 95/16

= 5¹⁵/₁₆
