Given:
The expression is:
[tex]\sqrt{1.69}-\sqrt[3]{0.001}[/tex]
To find:
The value of the given expression.
Solution:
We have,
[tex]\sqrt{1.69}-\sqrt[3]{0.001}[/tex]
On simplification, we get
[tex]\sqrt{1.69}-\sqrt[3]{0.001}=1.3-0.1[/tex]
[tex]\sqrt{1.69}-\sqrt[3]{0.001}=1.2[/tex]
Therefore, the value of the given expression [tex]\sqrt{1.69}-\sqrt[3]{0.001}[/tex] is 1.2.

Solve the system of equations 3x+2y=223x+2y=22 and -4x+3y=16−4x+3y=16 by combining the equations.
Answer:
(2, 8)
Step-by-step explanation:
Given the system of equation
3x+2y=22 ... *4
-4x+3y=16 .... *3
Using the elimination method
12x + 8y = 88
-12x + 9y = 48
Add
8y + 9y = 88+48
17y = 136
y = 136/17
y = 8
Recall that
3x+2y=22
3x+2(8)=22
3x + 16 = 22
3x = 22-16
3x = 6
x = 6/3
x = 2
Hence the required solution (x, y) is (2, 8)

A biologist was sitting near a pond and noticed a large number of dragonflies. He also saw both frogs and fish trying to eat the
dragonflies. He counted a total of 89 fish, frogs, and dragonflies. He noticed that there were four times as many dragonflies as fish and
that the frogs were five more than twice the number of fish
89 /3
frogs = 29.6
fish = 29.6
dragonflies = 29.6
all of them equal 89
How many combinations with repetition are allowed if n = 5 and r = 3?
120
125
10
35
Answer:
35
Step-by-step explanation:
Since repetition is allowed, we use the equation
((n+r-1)!/(r!(n-1)!) = 7!/(3!x4!) = 35
12 + 6x > 18

Answer:
I used math-way, solved for x and got this
x>1
Step-by-step explanation:
A kind teacher gives you 20 cents for every question you get right, but you have to pay the
teacher 10 cents for every question you get wrong. After 30 questions you have made a
profit of $1.80.
a ) Form an equation with x representing the number of questions you got right.
b )Solve your equation to find how many questions you got right.
Answer:
Let n be the number of questions you got right. Then
30-n equals the number of questions you got wrong.
So:
A) 20n-10(30-n)=180
30n-300=180
30n=480
n=16
30-n=14
B)You got 16 questions right and 14 questions wrong.

Find the value of x in OQ. 5x-6
2x+9
Need help with this question asap!!
Answer:
[tex]\huge\boxed{\sf x = 5}[/tex]
Step-by-step explanation:
Since, the chord is being bisected by the diameter (being divided into two equal parts). Hence,
5x - 6 = 2x + 9
5x - 2x = 9 + 6
3x = 15
Divide both sides by 3
x = 15 / 3
x = 5

$100 are shared between Adam and Hamza in the ratio 1:3.
A)
How many dollars did Adam receive?
How many dollars did Hamza receive?
Answer:
$25 for Adam and $75 for Hamza
Step-by-step explanation:
$100 will be divided to 3 + 1 = 4 parts
the dollars Adam received
= $100 × 1/4
= $25
the dollars Hamza received
= $100 × 3/4
= $75
-----------------------------------------------------------
the dollars Hamza give to Adam
= $75 × 25%
= $75 × 25/100
= $18.75
the dollars Adam have
= $25 + $18.75
= $43.75
the dollars Hamza have
= $75 - $18.75
= $56.25
the ratio
= 43.75：56.25
= 7：9

Find an equation of variation in which y varies directly as x and y = 60 when x = 0.4. Then find the value of y when x = 2
Answer:
y = 300
Step-by-step explanation:
The equation of variation in which y varies directly as x is written Mathematically as:
y ∝ x
y = k × x
y = kx
Where k = Proportionality Constant
We find k
a) y = 60 when x = 0.4.
60 = 0.4 × k
k = 60/0.4
k = 150
b) find the value of y when x = 2
y = kx
k = 150
Hence,
y = 150 × 2
y = 300
