Answer:
y = 36
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y = [tex]\frac{kz}{x}[/tex] ← k is the constant of variation
To find k use the condition y = - 18, z = 3 when x = 6 , then
- 18 = [tex]\frac{3k}{6}[/tex] ( multiply both sides by 6 )
- 108 = 3k ( divide both sides by 3 )
- 36 = k
y = [tex]\frac{-36z}{x}[/tex] ← equation of variation
When x = 5 and z = - 5, then
y = [tex]\frac{-36(-5)}{5}[/tex] = [tex]\frac{180}{5}[/tex] = 36

The cost of 6 CDs are $12, $13, $20, $20, $12.50 and $18.50. What is the
mean
Answer:
$16
Step-by-step explanation:
Find the mean by adding all of the costs, and dividing it by 6, since there are 6 CDs
(12 + 13 + 20 + 20 + 12.5 + 18.5) / 6
96 / 6
= 16
So, the mean is $16
Melanie invested $3800 in an account paying in interest rate of 2 3/8% compounded quarterly Sebastian invested $3800 in an account paying in interest rate of 2 3/4% compounded monthly after 16 years how much more money with Sebastian have in his account then Melanie to the nearest dollar
Answer:
$317
Step-by-step explanation:
Formula for compound interest is;
A = P(1 + (r/n))^(nt)
For melanie;
P = $3800
r = 2⅜% = 0.02375
n = 12/4 = 3
t = 16 years
Thus;
A = 3800(1 + (0.02375/3))^(3 × 16))
A ≈ $5548
For Sébastien;
P = $3800
r = 2¾% = 0.0275
n = 12
t = 16
Thus;
A = 3800(1 + (0.0275/12))^(12 × 16))
A ≈ 5865
Difference between Sébastien and Melanie's final amount = $5865 - $5548 = $317

3(x+8)2 + 8 = 83
3(x+8)2 = 75
Step 1
(x + 8)2 = 225
Step 2
X + 8 = +15
Step 3
X = 7 or x = -23 Step 4
Answer:
Step-by-step explanation:
I think you mean 3(x+8)², not 3(x+8)2. If you cannot type ², use ^ to mark the exponent: 3(x+8)^2.
3(x+8)² + 8 = 83
3(x+8)² = 75
(x+8)² = 25
x+8 = ±√25
x+8 = ±5
x = -8 ± 5 = -3, -13

Anita has a success rate of 80% on free throws in basketball. She wants to know the estimated probability that she can make exactly four of five free throws in her next game. How can she simulate this scenario?
Categorize each simulation of this scenario as correct or incorrect.
Roll a six-sided die five times. The
numbers 1 to 4 represent a make,
and numbers 5 and 6 represent a
miss.
Spin a spinner with three equal
sections five times. On the spinner,
one section represents a miss and
two sections represent a make.
Generate a set of five numbers using
a number generator with the numbers
0 to 9.The numbers 0 to 7 represent a
make, and 8 and 9 represent a miss.
Generate a set of five numbers using
a number generator with the numbers
0 to 5.The numbers 0 to 3 represent a

Spin a spinner with five equal sections
five times. On the spinner, four sections
represent a make and one section
represents a miss.

Answer:
a = 30°
b = 11°
Step-by-step explanation:
JK = 360 - 110 - 130 - 54 = 66°
Inscribed angles = 1/2 their arc
∠K = 1/2(130 + 54) = 92°
∠J = 1/2(110 + 130) = 120°
∠M = 1/2(66 + 110) = 88°
8b = 88°
b = 11°
∠L = 1/2(54 + 66) = 60°
2a = 60°
a = 30°
How much sales tax would you pay for a $55 pair of roller blades if the tax rate is 6.625%?
Answer:
419 or 419.37
Step-by-step explanation:
55 x 6.625 = 364.375
364.375 = 364.37 (Rounded to the Nearest 10)
55 + 364.37 = 419.37
--------------------------⭐OR⭐------------------------------
55 x 6.625 = 364.375
364.375 = 364 (Rounded)
55 + 364 = 419

1 kg = 1,000 g
Answer: 13440 grams
Step-by-step explanation:
Since 1 kg is 1000 g, multiply 0.64 by 1000 to find how many grams are in a kilogram.
0.64x1000
=640 grams
She uses 640 grams each day.
How many grams does he use in 3 weeks?
1 week has 7 days
3 weeks has 21 days
3x7=21

Find the measure of the arc or central angle indicated by the question mark. Assume that lines which appear to be diameters are actually diameters. PLEASE HELP AND SHOW WORK
Answer:
The measure of the arc length is 62 degrees
Step-by-step explanation:
Here, we want to find the given arc measure
Mathematically, we are going to use the angle arc relationship
For the angle arc relationship, the measure of the central angle is simply the measure of the arc
In this case, the central angle is 62: this means that the given arc measure is 62 degrees too
What is the value of s? Uhm uh why is this so difficult.
Answer:
s = 47
Step-by-step explanation:
The measure of the exterior angle of a triangle is equal to the sum of the opposite interior angles
s+45 = s+6 + s-8
Combine like terms
s+45 = 2s-2
Subtract s from each side
s+45-s =2s-2-s
45 =s-2
Add 2 to each side
45+2 = s-2+2
47 =s
