find the exact value of tan30⁰ × cos30⁰
give your answer in its simplest form
ANSWER:
tan(30⁰)=√3/3
cos(30⁰)=√3/2
switch sides:sin(x) /√3/2 =√3/3
multiply both sides by 3:3·sin(x) /√3/2 =3·√3/3
simplify:2√3 sin (x) =√3
divide both sides by 2√3:2√3 sin (x) / 2√3 = √3 / 2√3
simplify:sin (x)= 1/2

If bcd~gef find value of x
Answer:
[tex]x = 13[/tex]
Step-by-step explanation:
Given
See attachment
Required
Find x
From the attachment, we have:
[tex]BC = x + 4[/tex]
[tex]BD = 2x - 7[/tex]
[tex]GE = 51[/tex]
[tex]GF = 57[/tex]
Because both triangles are similar, we use the following equivalent ratios:
[tex]BC : BD = GE : GF[/tex]
Substitute values for each parameter
[tex]x + 4 : 2x- 7 = 51 : 57[/tex]
Convert to fractions
[tex]\frac{x + 4}{2x- 7} = \frac{51 }{ 57}[/tex]
Simplify the right-hand side
[tex]\frac{x + 4}{2x- 7} = \frac{17}{19}[/tex]
Cross Multiply
[tex]19(x + 4) = 17(2x - 7)[/tex]
[tex]19x + 76 = 34x - 119[/tex]
Collect Like Terms
[tex]19x - 34x = -76 - 119[/tex]
[tex]-15x = -195[/tex]
Solve for x
[tex]x = \frac{-195}{-15}[/tex]
[tex]x = 13[/tex]
Answer: x=13
Step-by-step explanation:
:(x+4) 57 = (2x-7) 5157x + 228 = 102x - 357357+228 = 102x - 57x585 = 45x13 =

Mae Ling earns a weekly salary of $325 plus a 7.5% commission
on sales at a gift shop. How much would she make in a work week if she sold
$5,800 worth of merchandise? Write in money format.
Answer:
$760
Step-by-step explanation:
Given data
weekly = $325
commission= 7.5%
if she sold $5,800 worth of merchandise
Her earnings will be
Week earning= base salary+ 7.5% of sales
Week earning= 325+ 7.5/100*5800
Week earning= 325+ 0.075*5800
Week earning= 325+ 435
Week earning= $760

solving 2 step inequalities give three solutions for each inequality -3(1-z)<9
Answer:
-3, -2 and -1
Step-by-step explanation:
Given the inequality -3(1-z)<9
Expand
-3(1)-3z <9
-3-3z <9
Add 3 to both sides
-3-3z+3<9+3
-3z<12
Divide both sides by -3
-3z/-3 >12/-3
z > -4
The required solutions are values greater than -4 and they are -3, -2 and -1

What is the value of E(-1) n (3n+2)?
====================================================
Explanation:
The weird looking E symbol is the greek uppercase letter sigma. It refers to a sum.
It tells us to add up terms in the form (-1)^n*(3n+2) where n is an integer ranging from n = 1 to n = 4.
------------------
If n = 1, then we have
(-1)^n*(3n+2) = (-1)^1*(3*1+2) = -5
Let A = -5 as we'll use it later.
------------------
If n = 2, then
(-1)^n*(3n+2) = (-1)^2*(3*2+2) = 8
Let B = 8 since we'll use this later as well
------------------
If n = 3, then
(-1)^n*(3n+2) = (-1)^3*(3*3+2) = -11
Let C = -11
-------------------
If n = 4, then
(-1)^n*(3n+2) = (-1)^4*(3*4+2) = 14
Let D = 14.
--------------------
We'll add up the values of A,B,C,D to get the final answer
A+B+C+D = -5+8+(-11)+14 = 6
This means that
[tex]\displaystyle \sum_{n=1}^{4}(-1)^n(3n+2) = 6[/tex]

Answer:
y > 4x - 2
Step-by-step explanation:
y-intercept is at -2
slope is rise by 4, run by 1
if you don't know where to shade, select a point and plug it in to see if T or F
example (0, 0)
is 0 > 4(0) - 2
is 0 > -2 True, so shade to the left because this is where (0,0) is
Answer:
Step-by-step explanation:
Analyze what each part of the inequality means mathematically.x is the solution of the problem, the quantity you are looking for.6x means that, for a reason given in the problem, the quantity you are looking for is multiplied by 6.− 18 means that, for a reason given in the problem, 18 is subtracted from 6x.≤ 18 means that after multiplying the solution x by 6 and subtracting 18 from it, the result is at most 18.Think of some different situations in which a quantity x might be multiplied by 6.You plant 6 seeds from x different seed packets, and you want to know from how many different seed packets you plants seeds.Build on the situation and adjust it to create a verbal description that takes all of the information of the inequality into account.Elrich planted 6 seeds from each of x different seed packets in his garden. To plant these seeds, he had to remove 18 plants that were already in the garden. Including the plants he removed and the seeds he planted, he expected to have at most 18 plants in the garden. From how many different seed packets did Elrich recently plant seeds?

Suppose you are given two quadrilaterals, ABCD EFGH. If the similarity ratio of ABCD to EFGH is 4:3, and it EH =
60, find AD
a. 45
0.90
b. 40
d. 80
Please select the best answer from the choices provided
B
Look at image^^^
Answer:
d. 80
Step-by-step explanation:
Similarity ratio of ABCD to EFGH = 4:3.
This implies that the ratio of AD to EH = 4:3
If EH = 60, then:
AD:60 = 4:3
AD/60 = 4/3
Multiply both sides by 60
AD = ⁴/3 × 60
AD = 80
