Jack manages a café. Each day he buys watermelons and mangoes in the (respective) ratio of 3:2. If on one day he buys 200 mangoes how many water melons would he have bought?
Answer:
300 watermelons
Step-by-step explanation:
3:2 ratio
3 is water melons and 2 is mangoes.
200 mangoes were purchased.
200/2=100
The unit rate is 100, so multiply 3 by 100, which is 300.
So Jack bought 300 watermelons, and 298 of which will be devoured by yours truly.

3. At a manufacturing plant, it is known that 8% of the computer chips produced are defective. A random sample of 20 chips is taken.
What is the probability that 3 of those chips are defective?
.
Answer:
Probability of three chip being defective is 0.012
Step-by-step explanation:
Probability of a computer chip being defective is 0.08 or 8%
Total random sample = 20
Probability of three chip being defective = 3/20 * 0.08
= 0.012
Answer:
B) 0.14
Step-by-step explanation:
N=20
K=3
P=0.08
CoE= 1140
1140 x (0.08)^3 x (.92)^17
1140 x (0.000512) x (0.2423) = 0.141425 or B

Set up an equation for the value of x.
Answer:
x = 27
Step-by-step explanation:
∠ GAF = 90° , then
x + 63 = 90 ( subtract 63 from both sides )
x = 27
Answer:
27
Step-by-step explanation:
Angle x and 63 are complementary angles forming 90
Therefore,
90 - 63 = x
27 = x

Solve the equation 3(+4.5)=36
What is the value of x?
Answer:
x=7+1/2
Step-by-step explanation:
We move all terms to the left:
3(x+4.5)-(36.)=0
We add all the numbers together, and all the variables
3(x+4.5)-36=0
We multiply parentheses
3x+13.5-36=0
We add all the numbers together, and all the variables
3x-22.5=0
We move all terms containing x to the left, all other terms to the right
3x=22.5
x=22.5/3
x=7+1/2

Answer:
Circle
Step-by-step explanation:
Examples of conic sections are the circle, the ellipse, the parabola and the hyperbola. Parametric equations are used to express the x and y variables in terms of a less complicated manner using a third variable (t or θ).
The parametric equation for a circle with an equation [tex](x-h)^2+(y-k)^2=r^2[/tex] is given by:
[tex]x=rcos(t)+h, y=rsin(t)+k[/tex]
where r is the radius of the circle and (h, k) is the center of the circle.
A conic section with a parametric equations X=3cos(t)-1, y=3sin(t)+4 is a circle with center at (-1, 4) and radius of 3. The equation of the circle is:
(x + 1)² + (y - 4)² = 3²

Chelsey wants to join a fitness club. The fitness club charges an initial membership fee of $55 and a monthly fee of $19.50. She has $250 to spend on a membership at the fitness club. Which equation represents the situation? If m is the number of months.
55 + 19.50m = 250
55m -19.50 = 250
55 - 19.50m = 250
55m +19.50 = 250
Help plz

Keisha's softball team won 60% of 135 games, how much games did the team lose?
Answer:
54
Step-by-step explanation:
135(.6) = 81
total = 135
won = 81
lost = 54
OR you could just multiply 135 by 110%-60%, which is 40% or 0.4
135(.4) = 54
Find measure angle GJK (5x + 8) (7x - 16)
Hi there!
[tex]\large\boxed{22^o}[/tex]
Find m∠GJK by finding the value of its complementary angle and subtracting from 90°.
Using the Alternate Interior Angle theorem:
m∠HJI = m∠JHG, so:
7x - 16 = 5x + 8
Solve for x:
2x - 16 = 8
2x = 24
x = 12
Substitute in this value of x to solve for m∠HJI:
7(12) - 16 = 84 - 16 = 68°
Thus:
m∠GJH = 90 - 68° = 22°
write the answer as a decimal to the nearest tenth

Elijah puts $550 in an account earning 8% simple interest annually. What is the total amount of money he will have in his account after 6 years, if no withdrawals or deposits are made?
Answer:
814?
Step-by-step explanation:
Simple interest is I = PRT, so you can multiply the 550, by 1.08 by 6 to get the total.
The principal is 550, the rate is 0.08 (using 1.08 because the prior gives interest, and using a whole 1 with it will be the total), and the time is 6 years because the interest is simple annual.
use 0.08 instead of 1.08 when solving for interest.

If x is an even number , the function f(x) = 2x-1 gives an odd number. Identify the set of odd numbers corresponding to this set of even numbers: {0,2,4,6,8}
Answer:
{-1, 3, 7, 11, 15}
Step-by-step explanation:
f(x) = 2x − 1, {0, 2, 4, 6, 8}
f(0) = 2*0 − 1 = 0 - 1 = -1
f(2) = 2*2 − 1 = 4 - 1 = 3
f(4) = 2*4 − 1 = 8 - 1 = 7
f(6) = 2*6 − 1= 12 - 1 = 11
f(8) = 2*8 − 1= 16 - 1 = 15
Austin’s monthly gross pay is $4,200. Federal withholding is 16.05% of his pay. His other deductions total $321.30. What is his net pay.
Answer:
$3,204.6
Step-by-step explanation:
$ 4,200 represents 100% of his salary
x amount of $ represents 16.05 % in federal withholding
after you line up $ with $ and % with % think cross multiplication
x = 4,200* 16.05/ 100 = $674.1 is the amount in federal withholding
Net pay = 4,200 -674.1 -321.30 = $3,204.6
