Answer:
[tex]\sqrt{19} - 4 \\or\\ - \sqrt{19} - 4[/tex]
Step-by-step explanation:
[tex]x^2+8x-3=0 \Rightarrow x^2+2.4.x+16-19=0\\\Rightarrow (x+4)^2=19 \\Then\\ x+4 = \sqrt{19} \Rightarrow x= \sqrt{19} - 4 \\or\\x+4 = -\sqrt{19} \Rightarrow x= -\sqrt{19} - 4[/tex]

Roger has to place cookies in plastic bags for a bake sale. He has 84 sugar cookies and 66 chocolate chip cookies. He wants to place the same number of cookies in each bag, wants to make sure that only one type of cookie goes into each bag, and wants to put the most cookies he can in each bag. How many cookies should be in each bag
Answer:
6 cookies
Step-by-step explanation:
Roger wants to place 84 sugar cookies and 66 chocolate chip cookies into plastic bags. Each bag must have the same number of cookies and only one type of cookie must be in each bag.
For the 84 sugar cookies:
number of cookies : 1 2 3 4 6 7 12 14 21 28 42 84
number of bags : 84 42 28 21 14 12 7 6 4 3 2 1
For the 66 chocolate cookies:
number of cookies : 1 2 3 6 11 22 33 66
number of bags : 66 33 22 11 6 3 2 1
The maximum common factor between 84 and 66 is 6.
Therefore 6 cookies should be placed in each bag. For sugar cookies, 6 cookies would be placed in each of the 14 bags while for the chocolate cookies, 6 cookies would be placed in each of the 11 bags.

Jerome makes and sells his own energy drinks. He mixes powdered drink mix with water to create his own special blend.
Jerome usually uses 8 cups of water and 3 cups of drink mix. Tomorrow, there is a road race in town, however, and Jerome thinks he’ll be able to sell a lot more of his energy drinks than usual.
Jerome’s brother told him to add one cup of water for every one cup of drink mix he added to keep the ratio of water to drink mix the same and still increase the total amount of energy drink.
Jerome’s sister told him to multiply both the amount of water and the amount of drink mix by the same number to keep the ratio the same and still increase the total amount of energy drink.
Who is correct: Jerome’s brother or Jerome’s sister?
Answer:
Jerome's brother

Answer:
{Segments, Geometric mean}
{PS and QS, RS}
{PS and PQ, PR}
{PQ and QS, QR}
Step-by-step explanation:
The three geometric mean relationships are derived from the similarity of the triangles the similarity proportions can be written 3 ways, each giving rise to one of the geometric mean relations.
short leg : long leg = SP/RS = RS/SQ ⇒ RS² = SP·SQ
short leg : hypotenuse = RP/PQ = PS/RP ⇒ RP² = PS·PQ
long leg : hypotenuse = RQ/QP = QS/RQ ⇒ RQ² = QS·QP
I find it easier to remember when I think of it as the segment from R is equal to the geometric mean of the two segments the other end is connected to.
__
segments PS and QS, gm RS
segments PS and PQ, gm PR
segments PQ and QS, gm QR
If you receive 25\% off an item costing $22.00, how much money do you save?
Answer:
5.50
Step-by-step explanation:
They save 5.50
Answer:
$5.50

Hello! This is an easy one. If we are trying to find how much she is saving all we would need to do is multiply.
$22.00 * 25% = $5.50
If we are trying to find out the total with the discount all we would need to do is subtract.
22 - 5.5 = $16.50
Hope this helps!!

Step-by-step explanation:
A furniture salesman makes 3.5% commission. Her monthly sales are $18,545. Her annual salary is $18,995.80. What’s her monthly pay? Write just the value that represents your answer.
Using proportions, it is found that her monthly salary is of $1,528.9.
What is a proportion?A proportion is a fraction of total amount.
In this problem, her monthly sales are $18,545, with a commission of 3.5%, hence, in commission, the amount she makes is:
0.035 x 18545 = 649.075
Her annual salary is $18,995.80, of which 18995.80 - 649 = $18,346.8 she receives in 12 payments, hence:
18,346.8/12 = $1,528.9.
Her monthly salary is of $1,528.9.

Yi Min owns a small store. The first month the store was

'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
60% = 60/100 = 60 ÷ 100 = 0.6.
100% = 100/100 = 100 ÷ 100 = 1.
