Answer:

1) A

2) x = 60

Step-by-step explanation:

1) A cuz complementary these two angles add up to be 90 degrees

Jerome, kevin and seth shared a submarine sandwhich. Jerome ate 1/2 of the sandwich , kevin ate 1/3 of the sandwich, and seth at

Paul [167]

Given:

Jerome ate 1/2 of the sandwich , Kevin ate 1/3 of the sandwich, and Seth ate the rest.

To find:

The ratio of jerome's share to kevin's share to seth's share.

Solution:

Jerome ate 1/2 of the sandwich. So,

Jerome's share = $\dfrac{1}{2}$

Kevin ate 1/3 of the sandwich. So,

Kevin's share = $\dfrac{1}{3}$

Seth ate the rest. So,

Seth's share = $1-\dfrac{1}{2}-\dfrac{1}{3}$

= $\dfrac{6-3-2}{6}$

= $\dfrac{1}{6}$

The ratio of jerome's share to kevin's share to seth's share is:

$\dfrac{1}{2}:\dfrac{1}{3}:\dfrac{1}{6}$

To simplify the ratio multiply the ratio by 6.

$\dfrac{1}{2}\times 6:\dfrac{1}{3}\times 6:\dfrac{1}{6}\times 6$

$3:2:1$

Therefore, the ratio of jerome's share to kevin's share to seth's share is 3:2:1.

The sales team at an electronics store sold 48 computers last month. The manager at the store wants to encourage the sales team

Ivahew [28]

Answer: a. 14 Computers

b. 62 Computers

Step-by-step explanation:

a) What is the amount of increase in computers needed?

Number of Computers sold last month = 48

Percentage increase required = 30%

Amount of increase in computers needed= 30% × 48

= 0.3 × 48

= 14.4

= 14 approximately

b)What is the new amount of computers the team must sell?

This will be the amount of Computers sold last month plus the increase.

= 48 + 14

= 62 Computers

Write a recursive rule for the sequence. 7, 6, 13, 19, 32, ...

allsm [11]

Answer:

recursive rule for the given sequence:

$a_n = a_{n-1}+a_{n-2}$ for n > 2

Step-by-step explanation:

Given the sequence:

7, 6, 13, 19, 32, ......

then;

First term $(a_{1})$ = 7

Second term $(a_{2})$ =6

third term $(a_{3})$ = 13 and so on..

You can see that:

$a_3 = a_1+a_2 = 6+7 = 13$

similarly for:

$a_4 = a_2+a_3 = 6+13 = 19$ and so on..

The recursive rule for this sequence is:

$a_n = a_{n-1}+a_{n-2}$ for n > 2

Which graph is the graph of y=⌈x⌉ over the domain 3≤x≤6 ?<br><br> (Graphs below)

bezimeni [28]

The bottom right graph is correct. x must fall between 3 and 6, so that automatically rules out the bottom left, as one of the points falls on 2.

the top left is incorrect because it doesn't show that x is greater than or EQUAL to three. it has an open circle rather than a closed circle. that's two answer choices eliminated.

from there, you just have to refer back to your given information:

<span>3≤x≤6

the given info says that x must be between or equal to 3 and 6. the top right graph leaves out a "step" because it has 5 and 6 as solid dots side by side.</span>
