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?
Answers
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.

CD is the Diameter. The measure of Arc CD is 11x Find the length of the radius in the circle.
Answers
Answer:
11
Step-by-step explanation:
Using S = rA, where S is arc length, r is radius and A is angle(in radians).
Comparing: S = 11π, A = 180° = π
=> 11π = rπ
=> 11 = r
Required radius is 11 unit
Method 2:
This is a semi circle, circumference of semi circle is πr, so
πr = 11π
r = 11

Find measure angle GJK (5x + 8) (7x - 16)
Answers
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°

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?
.
Answers
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

-10x+30+25x
25x-10x+30
15x+30
15(x+2)
Step-by-step explanation:
The factored form of the given expression is 15(x + 2).
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given expression is as below,
−5(2x − 6) + 25x
It can be simplified as follows,
−5(2x − 6) + 25x
= -10x + 30 + 25x
= 15x + 30
= 15(x + 2)
Hence, the given expression can be simplified in factored form as 15(x + 2).

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

Is the statement true or false?
If x = 6, then x can
only be equal to 6.
True
False
Copyright © 2003 - 2021 Asellus Corporation
Answers
The answer is false
The statement "If |x| = 6, then x can only be equal to 6" is false.
The absolute value of a number represents its distance from zero on the number line.
The expression |x| = 6 means that the distance of x from zero is 6. Therefore, x can be either positive or negative 6.
In this case, x can be either 6 or -6 because both numbers have an absolute value of 6.
Hence, x is not limited to being equal to only 6.

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?
Answers
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.
