Juli buys a flat with 48 flowers. She was wants to plant them in equal rows of 5 flowers. How many rows can Juli plant? How many

miss Akunina [59]

Answer:

5 row, 3 left

Step-by-step explanation:

She has 48 flowers, 5 flowers one row

How many rows can she make? So divide

48/ 5

= 9.6

So she can only make 9 rows

The leftovers flowers are the flowers that didn't manage to make 5 per row

Therefore, if she can make 9 rows, in other words 9 x 5 = 45

45 flowers were able to be placed in a sequence of 5 per row

So the ones that are left is

48 - 45

= 3

Given P(E)= 0.24 and P(FnE)= 0.17, find P(F| E). Round the answer to the nearest hundredth. A. 029 B. 0.40 C. 0.71 D. 1.41

romanna [79]

Given P(E) = 0.24 and P(F ∩ E) = 0.17

It says to find conditional probability of F given E has occurred.

We know the formula of conditional probability is given by :-

P(F ║ E) = $\frac{P(E\;and\; F)}{P(E)}$

P(F ║ E) = $\frac{0.17}{0.24}$ = 0.708333

P(F ║ E) = 0.71

Hence, option C i.e. 0.71 is the final answer.

Solve the inequality <br><br> −10 ≤ 2x - 4 < 8

Roman55 [17]

Answer:

- 3 is greater than or equal to x is greater than or equal to 6

Step-by-step explanation:

$- 10 \leq 2x - 4 \leq 8\\\\-10 + 4\leq 2x - 4 + 4\leq 8+4\\\\-6 \leq 2x \leq 12\\\\\\frac{-6}{2} \leq \frac{2x}{2} \leq \frac{12}{2} \\\\-3 \leq x \leq 6$

Hope this helps!!!!

Two triangles are similar.The the smaller triangle has side 10,20 and 15 units the larger triangles longest side is 52 units.Wha

Oliga [24]

Answer: The perimeter of the largest triangle = 117 units.

Step-by-step explanation:

Sides of smaller triangle = 10,20 and 15 units

Longest side = 20 units

Longest side of larger triangle = 52 units

Sides of two similar triangles are proportional.

Let k be proportionality constant.

$k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}$

$k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}$

Length of other two sides,

$10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}$

So sides of larger triangle = 52 units, 26 units , 39 units

Perimeter of largest triangle = 52 +26+39 = 117 units

Hence, the perimeter of the largest triangle = 117 units.
