Answer:
[tex]\sqrt{122}[/tex]
Step-by-step explanation:
Given that,
Vector n = 4i-j
Vector m = 3i+3j
We need to find the value of m+2n.
Put all the values,
m+2n = (3i+3j)+2(4i-j)
= (3i+3j)+8i-2j
=11i+j
Magnitude of vector,
[tex]|m+2n|=\sqrt{11^2+1^2} \\\\=\sqrt{121+1}\\\\=\sqrt{122}[/tex]
So the correct option is (c).

Answer:
Option P √2.5²-1.2²
Step-by-step explanation:
a = distance between Toby's House and the playground = 1.2 inches
b = distance between the playground and Toby's Friend's House = unknown
c = distance between Toby's House and Toby's Friend's House = 2.5 inches
Use the Pythagorean Theorem to calculate the side length of b:
a²+b²=c²
b²=c²-a²
b=√(c²-a²)
b=√(2.5²-1.2²)
Therefore, option P is correct.
Answer: it is p

(4-5x)+43=3-32(-82)
please answer!!
Answer:
x = -516
Step-by-step explanation:
(4 - 5x) + 43 = 3 - 32(-82) {Multiply 32 and (-82)}
4 - 5x + 43 = 3 - (-2624)
4 - 5x + 43 = 3 + 2624 {add 4 and 43 in LHS}
-5x + 47 = 2627 {Subtract 47 from both sides}
-5x = 2627 - 47
-5x = 2580 {Divide both sides by (-5)}
x = 2580/(-5)
x = -516

What is 3 1/4 x( -12.2)
Also pls answer it asap
Answer:
-39.65
Step-by-step explanation:
3 1/4 ⋅ (-12.2)
First, we must change the first fraction to a decimal.
3 1/4 = 3.25.
Now, we just multiply using standard algorithm.
3.25 ⋅ (-12.2) = -39.65.

A Businessman exchange Nepali currency rupees 660000 INR to US Dollar at the rate of Dollar 1 is equal to INR rupees 110 after 4 days Nepali currency is revaluated by 10% and he has changed the dollars INR to Nepali currency again what is his gain or loss find it
Answer:
Gain = $666.67
Step-by-step explanation:
The businessman exchanged 660000 INR to US Dollar using the exchange rate of $1 = INR 110
Value of the money in dollars is;
(660000 × 1)/110 = $6000
Now, Nepali currency is reevaluated by 10%. This means it's value has gone up by 10%.
Thus, exchange rate of $1 is now;
110 - 10%(110) = INR 99
Thus, 660000 INR to US Dollar using this new exchange rate gives;
(660000 × 1)/99 = $6666.67
Therefore he made a gain.
Gain = 6666.67 - 6000
Gain = $666.67

In a right triangle, if a = 8 and c = 17, what is the correct setup to find the value of b?
Answer:
b = 15
Step-by-step explanation:
Assuming that the question is referring c as the hypothenuse, the Pythegorean theorem states: [tex]a^2+b^2=c^2[/tex].
Thus, [tex]b=\sqrt{c^2-a^2}=\sqrt{17^2-8^2}=15[/tex].
So b is 15.
Answer: b = 15
Step-by-step explanation:
Here, we need to know the formula for the relationship between the three sides of the right triangle: a² + b² = c².
a and b are legsc is hypotenuse--------------------------------------------------------------------
Given
a = 8
c = 17
Solve
a² + b² = c²
(8)² + b² = (17)²
64 + b² = 289
b² = 225
b = √225
b = 15Hope this helps!! :)

A former sells 9.4 kilograms of pears and apples at the farmers market. 4/5 of this weight is pears and the rest is apples. How many kilograms of apples did she sell at the farmers market
Answer:
1.88
Step-by-step explanation:
A farmer sells 9.4 kilograms of pears and apples
4/5 of the total weight is pears while the rest is apple
Let x represent the number of apples
9.4= 4/5 ×9.4 + x
9.4 = 0.8×9.4+x
9.4 = 7.52+ x
9.4-7.52= x
1.88= x
x= 1.88

A stone is thrown horizantally with a velocity of 50 m/s from the top of a building. Find its velocity after 2 seconds.
Answer:
V = 53.7 m/s ∠-21.41°
Step-by-step explanation:
Since the stone's initial vertical velocity, u is 0m/s(since it is thrown horizontally), we find the stone's final vertical velocity, v from v = u - gt where u and v have the meanings as given above, g = acceleration due to gravity = 9.8 m/s² and t = time = 2 s
So, v = u - gt
v = 0 m/s - 9.8 m/s² × 2 s
v = 0 m/s - 19.6 m/s
v = - 19.6 m/s
Since the stone's horizontal velocity is u' = 50 m/s, we find the resultant magnitude of velocity V from V = √(u'² + v²)
So, V = √((50 m/s)² + (-19.6 m/s)²)
V = √(2500 m²/s² + 384.16 m²/s²)
V = √(2884.16 m²/s²)
V = 53.7 m/s
Its direction Ф = tan⁻¹(v/u')
Ф = tan⁻¹(-19.6 m/s/50 m/s)
Ф = tan⁻¹(-0.392)
Ф = -21.41°
So it velocity V = 53.7 m/s ∠ -21.41°

The area of the base of a box is 825 square centimeters. It has a height of 26 centimeters. What is the volume of the box in cubic centimeters?
Answer: 4950 cubic centimeters.
Step-by-step explanation:
We know that, the volume of box = Base area x height
Given: area of the base of a box = 825 sq. centimeters
height = 6 centimeters.
Then, Volume of the box in cubic centimeters = 825 x 6
= 4950 cubic centimeters.
hence, the volume of the box in cubic centimeters = 4950 cubic centimeters.

A cone has a volume of 100 cubic centimeters and a height of 12 centimeters. What is the
radius of the base of the cone in centimeters?
Hi there!
[tex]\large\boxed{r = 5 cm}[/tex]
The volume of a cone is as follows:
V = 1/3πr²h
We are given the volume and height, thus:
100π = 1/3πr²(12)
Begin by multiplying both sides by 3 (to cancel out the fraction):
300π = πr²(12)
Divide both sides by 12:
25π = πr²
Divide both sides by π:
25 = r²
Square root both sides:
5 = r
Answer:
the answer is 5 cm

A bag has 2 mint cookies, 1 donut, and 4 wafer cookies. Two items are drawn one at a time without replacement. What is the probability of first drawing 1 donut, and next drawing 1 mint cookie?
Answer: 1/21
Step-by-step explanation:
total = 2 + 1 +4 = 7
1/7 x 2/(7-1) = 2/42
2/42 simplifies to 1/21
1/7: 1 doughnut out of a total of 7 items
2/(7-1): 2 mint cookies are available in the pool out of 6 items -> since one item has already been chosen without replacement, so now the total is 6.
