on the scale of a map 4 cm represent 20 km if the distance between two points is 10 cm what is the actual distance between this points
Answer:
50 km
Step-by-step explanation:
Given
[tex]r = 4cm : 20km[/tex] -- Scale ratio
Required
Actual representation of 10cm
Let the actual measurement be x.
So, we have:
[tex]r =10cm:x[/tex]
Equate both value s of r
[tex]10cm : x = 4cm : 20km[/tex]
Express as fraction
[tex]\frac{x}{10cm } =\frac{20km}{4cm}[/tex]
Multiply by 10cm
[tex]10cm * \frac{x}{10cm } =\frac{20km}{4cm} *10cm[/tex]
[tex]x =\frac{20km}{4} *10[/tex]
[tex]x =5km *10[/tex]
[tex]x =50\ km[/tex]

Which expression is equivalent to 6/g^5 , if g >0
Answer:
The choose (D)
[tex] {g }^{ \frac{5}{6} } [/tex]
The expression equivalent to [tex]\sqrt[6]({g}^{5})[/tex] is [tex]g^{\frac{5}{6} }[/tex].
What is an exponent?The number of times a number has been multiplied by itself is referred to as an exponent. It could be an integer, a fraction, a negative integer, or a decimal. Powers or indices are other names for exponents. For instance, 6⁵ indicates that we are multiplying 6 by five. It is 6 × 6 × 6 × 6 × 6 in its expanded form.
How to solve this problem?The expression is [tex]\sqrt[6]({g}^{5})[/tex].
[tex]\sqrt[6]{g}[/tex] can be written as [tex]g^{\frac{1}{6} }[/tex].
Then the given expression can be written as [tex]g^{\frac{5}{6} }[/tex].
Therefore, the expression equivalent to [tex]\sqrt[6]({g}^{5})[/tex], g > 0 is [tex]g^{\frac{5}{6} }[/tex]. So, option D is correct.

is the point (2,5) a solution to the equation y=3x-5?
Answer and Step-by-step explanation:
To figure out, we plug in the x-value into the equation and see if it is equal to the y-value.
y = 3(2) - 5
y = 6 - 5
y = 1
5 ≠ 1
The point (2, 5) is not a solution.

Karim had a packet of 200 chocolates. He gave 35% of them to his sister. How many chocolates were left with him?
Answer:
Karim had 130 chocolates left.
Step-by-step explanation:
The quick way to do this is to notice that if he gave away 35% of his chocolates, he must have 65% left. That comes about by doing
100% (which is what he started with) - 35% = 65%
65% of 200 Change 65% into a fraction
65/100 * 200 Multiply 200 * 65
13000 / 100 Divide by 100
130
Answer:
130 left
Step-by-step explanation:
35% of 200 chocolates is equal to 70 chocolates.
200-70=130 chocolates

Answer:
sin θ = 12 / 13
Step-by-step explanation:
Given that :-
A right triangle having
Hypotenuse = 13
adjacent side ( Base ) = 5
Opposite side ( perpendicular ) = ?
To Find :-
sin θSolution :-
Firstly ,we need to find opposite side ( missing side ) of triangle
Using Pythagorean theorem
a ² + b ² = c ²
Where, a and b is the base and c is the height of triangle.substitute the value
( 5 ) ² + ( b) ² = ( 13 ) ²
evaluate the exponent
25 + b² = 169
subtract 25 from each side
25 - 25 + b² = 169 - 25
b ² = 144
Take the square root of each side
√b² = √144
b = 12
Hence , opposite side , b = 12
And , Finding sin θ
sin θ = opposite side / hypotenuse
sin θ = 12 / 13
To test this series for convergence
∝
∑ (4^n+7)/7^n
n=1
You could use the limit comparison test, comparing it to the series
∝
∑ r^n
n=1
Where r=???
Completing the test, it shows the series:
r should be 4/7. You're comparing the given series to a geometric series that converges. By the limit comparison test, you have
[tex]\displaystyle\lim_{n\to\infty}\frac{\frac{4^n+7}{7^n}}{\frac{4^n}{7^n}}=\lim_{n\to\infty}\frac{4^n+7}{4^n}=\lim_{n\to\infty}\left(1+\frac7{4^n}\right)=1[/tex]
and since this limit is positive and finite, and the series you're comparing to is convergent, then the first series must also be convergent.
Dan's car depreciates at a rate of 7% per year.
By what percentage has Dan's car depreciated after 6 years?
Give your answer to the nearest percent.
Answer:
20%
Step-by-step explanation:
Given that
The car is depreciated at a rate of 7% per year
We need to find out the percentage when the car is depreciated after 6 years
So,
Since the car is depreciated by 7% so we can say it can be 0.93 times in a year
Now after 6 years, it would make
= 0.93^3
= 0.80
So, the percentage is
= 1 - 0.80
= 0.20
= 20%

Answer:
[tex]2/3[/tex]
Step-by-step explanation:
The total number of sums (not distinct) is [tex]4\cdot 3=12[/tex], because we're removing without replacement.
Count the sums that fit the stipulation (sum [tex]\leq[/tex] 5):
[tex]1,2,\\2,1\\1,3\\3,1\\1, 4\\4, 1\\2, 3, \\3,2[/tex]
There are 8 sums that work. Therefore, the desired answer is [tex]\frac{8}{12}=\boxed{\frac{2}{3}}[/tex]
Suppose a normal distribution has a mean or 70 and a standard deviation of 7. What is P(x>=94)? O A. 0.075 O 8. 0.025 c. 0.84 OD 0,16
Answer:
0.025
Step-by-step explanation:
Mean = 79 ; Standard deviation = 7
P(x ≥ 93)
We obtain the ZSCORE :
Zscore = (x - mean) / standard deviation
x = 93
Zscore = (93 - 79) / 7 = 2
P(Z ≥ 2) = 0.02275

Your answer
Answer:
Jada should use the tank of golf balls
Step-by-step explanation:
Jada should choose the tank that has a higher probability of choosing a ball with even number from.
Tank of tennis balls has two even numbers out of the ten balls (2, 4)
Tank of golf balls has seven even numbers out of the ten balls.
Tank of golf balls would give Jada more chance to pick an even number to win the game
Therefore, Jada should use the tank of golf balls

Given the statement “If a line is horizontal, then it has slope equal to zero,” what is its contrapositive?
Answer:
"If the line has a slope that is not 0, then the the line is not horizontal".
Step-by-step explanation:
The contrapositive of "If p then q" is "If not q then not p".
p=a line is horizontal
not p= a line that is not horizontal
q=the line has a slope equal to zero
not q=the line has a slope that is not zero
The equivalent statement in contrapositive form is therefore:
"If the line has a slope that is not 0, then the the line is not horizontal".
