Mumz [18]

Answer:

1. No, because each x value can only have one y value (one-to-one relationship).

2. No, because each x value can only have one y value (one-to-one relationship).

3. Yes, because one member of the domain is assigned to one member of the range.

Step-by-step explanation:

Sila jogged 12 kilometers today and wants to know how far she traveled in feet. what error did sila make while converting from kilometers to feet?

StartFraction 12 kilometers Over 1 EndFraction times StartFraction 0.62 miles Over 1 kilometer EndFraction times StartFraction 5280 feet Over 1 mile EndFraction = 392,832 feet

sila put a wrong number in her calculator when multiplying the numerators.

1 km sila's first fraction should be 0 62 mi 1 mi

sila's last fraction should be 5280 ft

sila forgot to divide by 0 62 asap

(12kilometers / 1 ) × (0.62 miles / 1 kilometer) × 5280 / 1 mile

12 kilometers = 39,370.079 feet

1 kilometer = 0.621 miles

sila put a wrong number in her calculator when multiplying the numerators

Please help solve 1, and 2

Vadim26 [7]

Answer:

Step-by-step explanation:

1). WXYZ is a rectangle,

Properties of a rectangle,

i). Opposite sides are equal and parallel.

ii). All interior angles measure 90°.

iii). Diagonals are equal in measure.

a). WY = ZX = 30

Therefore, ZT = $\frac{1}{2}(ZX)$

$ZT=15$

b). WY = ZX = 45

c). Since, WY = ZX,

(4b - 16) = (3b + 5)

4b - 3b = 16 + 5

b = 21

2). GOAT is a rhombus and m∠OGA = 35°,

a). m∠TGA = m∠OGA = 35°

b). m∠GXO = 90°

c). m∠GXT = 90°

d). Since adjacent angles of a rhombus are supplementary,

m∠OGT + m∠GTA = 180°

70° + m∠GTA = 180°

m∠GTA = 110°

m∠GTO = $\frac{1}{2}(m\angle GTA)$

= $\frac{1}{2}(110^{\circ})$

= 55°

e). Since, opposite angles of a rhombus are equal,

m∠OGT = m∠OAT = 70°

f). m∠GOA = m∠GTA = 110°

A tank with a capacity of 100 gallons initially contains 50 gallons of water with 10 pounds of salt in solution. fresh water ent

steposvetlana [31]

Let $A(t)$ be the amount of salt (in pounds) in the tank at time $t$ . We're given that $A(0)=10\text{ lb}$ .

The rate at which the amount of salt in the tank changes is given by the ODE

$A'(t)=\dfrac{2\text{ gal}}{1\text{ min}}\cdot\dfrac{0\text{ lb}}{1\text{ gal}}-\dfrac{1\text{ gal}}{1\text{ min}}\cdot\dfrac{A(t)\text{ lb}}{50+(2-1)t\text{ gal}}$

$A'(t)+\dfrac{A(t)}{50+t}=0$

$(50+t)A'(t)+A(t)=0$

$\bigg((50+t)A(t)\bigg)'=0$

$(50+t)A(t)=C$

$A(t)=\dfrac C{50+t}$

Given that $A(0)=10$ , we find that

$10=\dfrac C{50+0}\implies C=500$

so that the amount of salt in the tank is described by

$A(t)=\dfrac{500}{50+t}$

The tank will be filled when $50+t=100$ , or after $t=50$ minutes. At this time, the amount of salt in the tank is

$A(50)=\dfrac{500}{50+50}=5\text{ lb}$
