We read $3\frac{1}{2}$ pages .

<u>Step-by-step explanation:</u>

Correct Question: You have to read 10 1/2 pages for homework. So far, you have read 1/3 of the assignment. How many pages did you read?

We have , to read 10 1/2 pages or $10\frac{1}{2}$ pages for homework . Till now we have read 1/3 of the assignment or $\frac{1}{3}$ of the assignment . We need to find How many pages did you read . Let's find out:

Basically we read 1/3 part of the 10 1/2 pages assignment i.e.

⇒ $10\frac{1}{2}(\frac{1}{3})$

⇒ $\frac{20+1}{2}(\frac{1}{3})$

⇒ $\frac{21}{2}(\frac{1}{3})$

⇒ $\frac{3(7)}{2}(\frac{1}{3})$

⇒ $\frac{7}{2}$

⇒ $3\frac{1}{2}$ pages

Therefore , We read $3\frac{1}{2}$ pages .

An airplane is traveling in the direction 20 degrees west of north at 700 km/hr. Find the component form of the velocity of the

OLga [1]

Answer:

(-239.4, 657.8) km/h

Step-by-step explanation:

Measured CCW from the +x axis, the angle at which the airplane is traveling is 110°. Then the (x, y) components of the velocity vector are ...

(700 km/h)(cos(110°), sin(110°)) ≈ (-239.4, 657.8) km/h

Which expression is equivalent to n2 + 26n + 88 for all values of n?

Lelechka [254]

Answer:

Option B is correct.

The expression which is equivalent to $n^2+26n+88$ is; $(n+22)(n+4)$

Explanation:

Given the equation: $n^2+26n+88$ for all values of n.

The quadratic equation in this form; $ax^2+bx+c =0$

First find two numbers that multiply to give ac and add to give b.

From the given equation;

a =1 , b = 26 and c =88

then,

the two number that multiply to give ac =88 is, 22 or 4

and they add up to give b=26 (i.e 22+4)

Now, rewrite the middle term i.e 26n with 22n and 4n , we have

$n^2+22n+4n+88=0$

Now, factor the first two terms and last two terms,

$n(n+22)+4(n+22)$

we see that $(n+22)$ is common to both terms so, we have;

$(n+22)(n+4)$

Therefore, the expression $(n+22)(n+4)$ is equivalent to $n^2+26n+88$

Check:

(n+4)(n+22) = $n\cdot n+ 22n+4n+88$ = $n^2+26n+88$ [ True]

Miya flips a coin and rolls a 6-sided number cube labled 1-6 and records tge outcome. About how many times is she likely to flip

neonofarm [45]

Answer:

4 times

Step-by-step explanation:

Sample space :

6 sided cube = (1, 2, 3, 4, 5, 6)

Coin = (H, T)

Probability = required outcome / Total possible outcomes

Probability of head (H) = P(H) = 1 /2 = 0.5

Probability of 3 = P(3) = 1 /6 = 0.166666

Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333

Hence, expected number of times this is likely to occur in 48 tries :

0.083333 * 48 = 4
