Answer:
75
Step-by-step explanation:
Number of necklace= k × amount of time spent
6= k × 2/5
K = 6÷2/5
K= 6×5/2
K= 15
Therefore the number of necklace made in 5 hours can be calculated as follows
15 = number of necklace ÷ 5
Number of necklace = 15 ×5
Number of necklace = 75

find all the zeros of the quadratic function
[tex]y = x^{2} - x - 20[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]y = {x}^{2} - x - 20[/tex]
[tex]y = (x - 5)(x + 4)[/tex]
To find the zeroes , Just need to put 0 instead of y .
[tex]0 = (x - 5)(x + 4)[/tex]
[tex](x - 5)(x + 4) = 0[/tex]
_________________________________
Hint :
[tex]a \times b = 0[/tex]
[tex]a = 0 \: \: \: or \: \: \: b = 0[/tex]
_________________________________
[tex]x - 5 = 0[/tex]
Add sides 5
[tex]x - 5 + 5 = 0 + 5[/tex]
[tex]x = 5[/tex]
Or
[tex]x + 4 = 0[/tex]
Subtract sides 4
[tex]x + 4 - 4 = 0 - 4[/tex]
[tex]x = - 4[/tex]
Thus the zeroes are :
( - 4 , 0 ) and ( 5 , 0 ) .

Using the Triangle Sum Theorem, find x and the missing angles (2x +1) (5x +5) x= Angle (2x+1) = Angle (5x+5) =
Answer:
x = 12
(2x + 1)° = 25°
(5x + 5)° = 65°
Step-by-step explanation:
By the property of a triangle,
Sum of all angles of a triangle is 180°
In the given right triangle,
(2x + 1)° + 90° + (5x + 5)°= 180°
7x + 96 = 180
7x = 180 - 96
x = [tex]\frac{84}{7}[/tex]
x = 12
Angle (2x + 1)° = 2(12) + 1 = 25°
Angle (5x + 5)° = 5(12) + 5 = 65°
Therefore, all three angles of the right triangle are 25°, 90° and 65°.
5x + 2y = 7
Solve for y

A rectangle of side 48cm by 60cm is divided into squares of side X cm. Find the greatest value of X
and find the area of the square.
Answer:
greatest value of X = 12
Area of square = 144 cm²
Step-by-step explanation:
The greatest value of X will be the highest common factor of 48 and 60 since we are told that the rectangle is divided into squares.
Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The highest common factor between both factors of 48 and 60 is 12.
Thus,
greatest value of X = 12
Area of square = 12 × 12
Area of square = 144 cm²
Find the slope of the line that goes through the points (9,-13) and (7,3).
hi
You have two points A ( X;Y) and B ( X ; Y)
slope is : ( Yb -Ya) / (Xb -Xa )
(3 - (-13) ) / ( 7 - 9) = (3 +13) / -2 = 16/-2 = - 16/2 = -8
slope is -8
Answer:
-8
Step-by-step explanation:
The slope formula is as follows:
m = y2 - y1 / x2 - x2
You would first plug in the points into the formula, and this is what you would get:
m = 3 - (-13) / 7 - 9
From there, because of additive inverse, the negative signs would become + signs.
m = 3 + 13 / 7 - 9
You would now add/subtract.
m = 16 / -2
And lastly, you would simplify.
m = 8/-1
8/-1 is the same thing as a slope of -8.
Which of the following inequalities is equivalent
to -31 + 12s <3s + 15 ?
Answer:
-31+12s
Step-by-step explanation:
The required inequality that is equivalent to -31 + 12s < 3s + 15 is 9s < 46.
Given that,
To determine the inequalities is equivalent to -31 + 12s <3s + 15.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
-31 + 12s < 3s + 15
12s - 3s < 15 + 31
9s < 46
Thus, the required inequality that is equivalent to -31 + 12s < 3s + 15 is 9s < 46.

Jack bought 500 shares in Glastonbury Goods at $17.85 per share on January 18, 2015. On January 25, 2017, he sold 300 shares after its price had dropped to $15.25 per share. He bought 250 more shares on January 31, 2017 when the price had fallen to $11.90 a share. He sold all of his stock at $18.00 per share on February 5, 2017. How much of a profit/loss did Jack make over the course of his investment? ____________________ profit or loss
Answer:
$775 profit
Step-by-step explanation:
Here, we want to know how much profit or loss Jack made;
he sold 300 shares at $15.25
Amount lost on this will be;
(17.85-15.25) * 300 = -$780
The number of shares he sold at $18 will be the 250 he bought now, and the 200 left unsold before
So profit now will be;
200(18-17.85) + 250(18-11.9)
= $30 + $1525 = $1555
So he made $1555 and lost $780
The amount of profit made is $1555-$780 = $775

A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes. How often do they blink at the same time?A.Every 14 minutesb.Every 24 minutesc.Every 48 minutesd.Every 2 minutes
Answer:
b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.

Brian bought a jacket that cost d dollars. He paid the clerk $60,00 He received $7.39
in change. How much did Brian pay for the jacket?
Answer:
52.61 is what Brian payed for the Jacket.
Step-by-step explanation:
52.61 + 7.39 = 60$ in total.
Answer:
ok so a jacket would never cost 60,00 i think you meant 60.00 so it would be $52.61 for the jacket
Step-by-step explanation:
Subtract 7.39 from 60
if you really did mean 60000 the answer would be 5992.61

The length of a rectangle is equal to triple the width. what is its width and length if its perimeter is 88 centimeters.
Answer:
56fifjjfiggitrireieisixii3eiirr
Answer:
Length = 33 cm
width = 11 cm
Step-by-step explanation:
a = 3w ⇒ eq. 1
88 = 2(a+w) ⇒ eq. 2
a = length
w = width
then:
replacing the value of the eq. 1 on the eq. 2
88 = 2(3w + w)
88/2 = 4w
44 = 4w
w = 44/4
w = 11 cm
from the eq. 1
a = 3w
a = 3*11
a = 33cm
Check:
perimeter = 88 = 2(a+w)
88 = 2(33+11)
88 = 2*44
