Answer:

19.1 cm

Step-by-step explanation:

the other side = √8.1²-7.1²=√65.61- 50.41

= √15.20 = 3.9

perimeter = 7.1+8.1+3.9= 19.1 cm

Answer: 500 meters

Step-by-step explanation:

Since he won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s, the speed will be:

= Distance/Time

= 500m/1 min 37.9s

= 500m/97.9s

= 5.11m/s

Since he also won the bronze medal in the 1000 m race, with a time of 3 min 28.2s, the speed will be:

= Distance/Time

= 1000/3 min 28.2s

= 1000m/208.2s

= 4.80m/s

Therefore, he rowed with greater speed in the 500 meters.

Note that 60seconds = 1 minute

Answer:

The mean number of children is 3.

Step-by-step explanation:

The mean of the data is 3

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Mean = (Sum of all the observations/Total number of observations)

The mean of the given data will be:

Answer:

I think its 72 cans

Tell me if I'm wrong!

Answer:

10.81 units

Step-by-step explanation:

Given data

point H ( -4,6 ) and point I ( 2,-3 )

x1= -4

y1=6

x2= 2

y2=-3

The formula for the distance between two points is

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-(-4))²+(-3-6)²)

d= √(2+4)²+(-9)²)

d= √(6)²+(-9)²)

d= √36+81

d=√117

d= 10.81 units

Hence the distance between the points is 10.81 units

Answer:

Step-by-step explanation:

The inverse function of [tex]f(x) = 1.5^x + 4[/tex] is [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]

In other words, the required answer is  [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]

To find the inverse of the function[tex]f(x) = 1.5^x + 4[/tex], we need to swap the roles of x and y and solve for y.

Start with the original function:

[tex]y = 1.5^x + 4[/tex]

Swap x and y:

[tex]x = 1.5^y + 4[/tex]

Solve for y:

Subtract 4 from both sides:

[tex]x - 4 = 1.5^y[/tex]

Take the logarithm (base 1.5) of both sides:

[tex]\log1.5(x - 4) = y[/tex]

Rewrite the equation with y as the subject:

y = log1.5(x - 4)

Therefore, the inverse function of [tex]f(x) = 1.5^x + 4[/tex] is [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]

In other words, the required answer is  [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]

[tex]l = 3.66[/tex]

Step-by-step explanation:

Given

[tex]r =1[/tex]

[tex]\theta = \frac{7\pi}{6}[/tex]

Required

The arc length (l)

This is calculated as:

[tex]l= r\theta[/tex]

So, we have:

[tex]l = 1 * \frac{7\pi}{6}[/tex]

[tex]l = \frac{7\pi}{6}[/tex]

So, we have:

[tex]l = \frac{7*3.14}{6}[/tex]

Step-by-step explanation:

Khan

We want to find the probability that Bob will randomly draw $30 in tokens. We will find that the probability is P = 1/6 = 0.167

The only case where he draws $30 randomly is when:

Then we need to find the probabilities for these two events.

For the first one, the probability will be equal to the quotient between the number of $5 tokens and the total number of tokens in the cup. There are 6 tokens in the cup and 2 of these are $5 tokens, then the probability is:

p = 2/6 = 1/3

For the second event the probability is computed in the same way, he has two tokens in his pocket and one of them is a $25 token, then the probability is:

q = 1/2

The joint probability, the probability that both of these events happen at the same time, is given by the product of the individual probabilities, so we get:

P = p*q = (1/3)*(1/2) = 1/6 = 0.167

So the probability that he draws $30 in tokens is P = 1/6 = 0.167.

Answer:

  a) Cat

  b) 8

  c) 6

Step-by-step explanation:

a) Each line contains one large square, at least. The smallest additional area is on the Cat line. Apparently, the fewest people preferred cats.

__

b) The smaller symbols appear to represent 1/4, 1/2, and 3/4 of the larger square. On that basis, we can add all of the symbols to discover there are a total of 10 of them:

  1 1/4 +1 3/4 +2 1/2 +1 1/2 + 3 = 8 + (1/4 +3/4) +(1/2 +1/2) = 8 +1 +1 = 10

Since 10 symbols represent 80 people, each large square symbol must represent 8 people.

__

c) The number preferring dogs is (1 3/4)(8) = 14. The number preferring giraffes is (2 1/2)(8) = 20. Then 20 -14 = 6 more people preferred giraffes.

Answer:

145° = m∠E

Step-by-step explanation:

Vertical Angles: always congruent, therefore, to find Angle E first find "x" ;

5x + 55 = 11x - 53

55 = 6x - 53

108 = 6x

108/6 = x

18 = x

Now that we know x-value is 18, u can substitute that in for the equation for Angle E for "x";

=> 5(18) + 55 = m∠E

=> 145° = m∠E
