Ok so, Since Kelli and her family drove a total of 293 miles in 7 hours, then your equation should be $\frac{293miles}{7hrs}$
Now, since you have your ratio you divide 293 by 7 in order to get how many miles were driven in one hour
$\frac{293}{7}$ = 41.85714286 miles/hr

You do 293 divided by 7 to get the answer.
The answer is 41.8 miles per hour.

Tell whether the statement is always, sometimes, or never true. Explain your reasoning.

sergeinik [125]

Answer:

a) sometimes
b) always
c) never
d) sometimes
e) never
f) always

Step-by-step explanation:

(a) Complementary angles are adjacent. sometimes

Complementary angles sum to 90°. They don't have to be adjacent.

(b) Angles in a linear pair are supplements of each other. always

That the angles are supplementary is part of the definition of a linear pair.

(c) Vertical angles are adjacent. never

Vertical angle share a vertex, but not a side. They cannot be adjacent.

(d) Vertical angles are supplements of each other. sometimes

Vertical angles are always congruent. If they are both 90°, then they will be supplementary.

(e) If an angle is acute, then its complement is greater than its supplement. never

The supplement of an angle is always 90° more than the complement of the same angle. The complement of an angle cannot be greater than its supplement.

(f) If two complementary angles are congruent, then the measure of each angle is 45°. always

Complementary angles sum to 90°, so if they have the same measure, that measure must be 45°.

The vector v has initial point P(1, 0) and terminal point Q that is on the y-axis and above the initial point. Find the coordina

zloy xaker [14]

Answer:

The terminal point is Q(0,4)

Step-by-step explanation:

We are given the following in the question:

Initial point of vector, P(1,0)

The terminal point Q lies on the y-axis, thus Q have coordinates of the form:

$Q(0,y)$

The magnitude of the vector is $\sqrt{65}$

Magnitude is given by:

$v = \sqrt{(x_2-x_2)^2+(y_2-y_1)^2}\\\sqrt{65}=\sqrt{(0-1)^2+(y-0)^2}\\\sqrt{65}=\sqrt{1+y^2}\\65 = 1+y^2\\y^2 = 64\\y = \pm 8$

But since the terminal point is above the initial point, thus,

$y > 0\\\Rightarrow y = 4$

Thus, the terminal point is Q(0,4)

PLEASE HELP ME ITS MY LAST QUESTION!!

shepuryov [24]

100 = 10^2

1000 = 10^3

10000 = 10^4

0.1 = 10^(-1)

0.01 = 10^(-2)

0.001 = 10^(-3)

Now,

100 × 0.1 = 10^2 × 10^(-1)

= 10

Bacteria tend to grow very fast in a Petri dish at first because of unlimited food and then begin to die out due

Assoli18 [71]

Answer:

6. Bacteria tend to grow very fast in a petri dish at first because of unlimited food and then begin to die out due

to competition. In a certain culture, the number of bacteria is givenby N(f) =1f +92t+.625' where /

represents the hours since 625 bac,teriawere introduced to the Petri dish. Determine the *={TlgX9"t

of bacteria that occur in the dish.

Step-by-step explanation:

t= -92/-2(2) =23

N (23) power 2 +92(23) + 625 =1628
