Over the past few years, Mitchell has made 99 trips to visit the amusement park. He drove 6,870.1 kilometers in all. To the nearest hundredth of a kilometer, how far did Mitchell drive on each trip?
Answer:
69.39 kilometers
Step-by-step explanation:
total kilometres driven on each trip = total kilometres driven on all trips / total number of visits
6,870.1 / 99 = 69.394949
To the nearest hundredth means we are rounding off the third number after the decimal point. The second number after the decimal is the hundredth. The third number is less than 4, so zero would be added to the preceding number
69.39 kilometers
How many kilograms of water must be added to 25 kilograms of a 15% salt solution to produce a 5% solution ?
Answer:
50kg
Step-by-step explanation:
25 kg of a 15% salt solution
25kg * 15%
25kg * 15/100 = 3.75 kg
3.75kg * 100/5
3.75 * 20 = 75
Mass of water in kg increased from 25kg to 75kg
75kg - 25kg = 50kg of water must be added.

For rectangle ABCD, find m∠ADB.
Answer:
we know all angles are 90° in the rectangle
therefore, angle d = bdc+bda = 90
=> 31+bda = 90
=>angle bda= 59
The measurement of the angle ADB should be considered as the 59 degrees.
Calculation of the measurement of the angle ADB:Since we know that all angles in the rectangle should be of 90 degrees
So,
Here angle d = bdc + bda
= 90
Now
31 + bda = 90
So, bda = 90 - 31
= 59
hence, The measurement of the angle ADB should be considered as the 59 degrees.

if a probability of a player a is 0.3 then the probability of a player b is how much?
Answer:
0.7
Step-by-step explanation:
The total probability is equal to 1
To find the probability of player b we take the probability of player a and subtract it from the total probability of 1
Hence 1-0.3=0.7
Answer:
0.7
Step-by-step explanation:
→ Minus 1 from the probabilities as all probabilities add up to 1
1 - 0.3 = 0.7

Answer:
Remember that for a triangle rectangle we have the Pythagorean's theorem, it says that the square of the hypotenuse is equal to the sum of the squares of the catheti.
Then if the catheti of a triangle rectangle are A and B, and the hypotenuse is H, we have:
H^2 = A^2 + B^2
In the smaller triangle we can see that:
H = 10
A = 6
Then:
10^2 = 6^2 + B^2
100 = 36 + B^2
100 - 36 = B^2
64 = B^2
√64 = B = 8
And we know that the perimeter of a triangle is equal to the sum of the lengths of it's sides, then the perimeter of the smaller triangle is:
P = 10 + 6 + 8 = 24
Now we know that the triangles are similar and related by a factor of 4/3, then each measurement of the larger triangle will be equivalent to 4/3 times the corresponding measurement of the smaller triangle, then if the measures of the larger triangle are A', B', and H', we can write these as:
A' = (4/3)*A = (4/3)*6 = 8
B' = (4/3)*B = (4/3)*8 = 10.67
H' = (4/3)*H = (4/3)*10 = 13.33
Then the perimeter of the larger triangle is:
P' = 8 + 10.67 + 13.33 = 32

Jonathan was 45 inches tall when he started kindergarten. He grew an average of 2.5 inches every year. Jonathan is now 62.5 inches tall. Which equation can be used to find how many years ago Jonathan started kindergarten, and how many years ago was it?
A. (45 + 62.5) ÷ 2.5 = x 7 years
B. 2.5x + 45 = 62.5 7 years
C. (45 + 62.5) ÷ 2.5 = x 43 years
D. 2.5x + 45 = 62.5 43 years
Answer:
B; 2.5x + 45 = 62.5
Step-by-step explanation:
Since the current height is 62.5, and the starting height is 45, then all you have to do is subtract 45 from 62.5, then divide that by 2.5 to get your answer, which should be 7 years.

All parallelograms have two pairs of opposite sides that are parallel and all squares are parallelograms. Based on this description, which statement is true?
A. All squares have two pairs of opposite sides that are parallel.
B. All squares have two pairs of opposite sides that are perpendicular.
C. All squares have four right angles.
D. All squares have four sides that are the same length.
cos B =
tan B =
sin B =
The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).
Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse
Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse
Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.
The acronym to remember this is SOHCAHTOA
SOH | CAH | TOA
SOH means sin(x) = opposite/hypotenuse
CAH means cos(x) = adjacent/hypotenuse
TOA means tan(x)= opposite/adjacent
cosB = length of adjacent side/length of hypotenuse = 7/25
tanB = length of opposite/length of adjacent = 24/7
sinB = length of opposite/length of hypotenuse = 24/25

Suppose a die is tossed 5 times. what is the probability of getting exactly 2 fours?
Answer:
the probability of getting exactly 2 fours is 0.16
Step-by-step explanation:
The probability of obtaining a number that is four = ¹/₆
The probability of obtaining a non 4 number = 1 - ¹/₆ = ⁵/₆
The number of ways 2 fours can be arrange in five numbers = ⁵C₂ = 10 ways
If the die is tossed five times, the probability of the events is calculated as;
P = 10 x (¹/₆)² x (⁵/₆)³
P = 10 x (¹/₃₆) x (¹²⁵/₂₁₆)
P = 10 x 0.02778 x 0.5787
P = 0.16
Therefore, the probability of getting exactly 2 fours is 0.16
The probability of exactly [tex]2[/tex] four's in [tex]5[/tex] tosses is [tex]0.1608[/tex].
Probability:Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are to happen, using it.
Let [tex]X[/tex] be the number of fours in [tex]5[/tex] coin tosses.
We have no. of tosses [tex]n=5[/tex].
Probability of a success i.e., getting four [tex](p)=\frac{1}{6}[/tex] and probability of not getting a four [tex](q)=\frac{5}{6}[/tex].
[tex]X[/tex] follows a binomial distribution. So,
[tex]P(X=x)=\binom{n}{x}p^{x}q^{n-x}[/tex]
[tex]\therefore[/tex] the probability of exactly [tex]2[/tex] four's in [tex]5[/tex] tosses is given by,
[tex]P(X=2)=\binom{5}{2}\left ( \frac{1}{6}^{2} \right )\left ( \frac{5}{6} \right )^{3}[/tex]

Does this triangle have a hypotenuse about 39 feet long
Answer:
hypotenuse is about 33 ft long
Step-by-step explanation:
a^2+b^2=c^2
a= 30
b=14
30^2+14^2= 1096 =c^2
[tex]\sqrt{1096}[/tex]=c
33.1=c
hypotenuse is about 33 ft long
Answer:
No, the Hypotenuse is 33.11
Step-by-step explanation:
The formula for finding a hypotenuse is:
[tex]\sqrt{x^2+y^2}[/tex]
x=30 and y=14 here
[tex]x^2=900[/tex]
[tex]y^2=196[/tex]
[tex]x^2+y^2= 1,096[/tex]
[tex]\sqrt{1,096} = 33.11[/tex]
So it would be about 33, not 39

9514 1404 393
Answer:
1) (1 1/2)(7/5) = g
2) (1 1/2)/(5/7) = g
Step-by-step explanation:
1) Tyler has painted 5/7 of the 7/7 of the fence. So the total amount of the fence is (7/7)/(5/7) = 7/5 as much as what was already painted.
The total amount of paint needed is then 7/5 the amount already used:
g = (7/5)(1 1/2) . . . . . gallons of paint needed for the whole fence
__
2) If g gallons are required for the whole fence, the amount used so far for 5/7 of the fence is 5/7 of the quantity required:
(5/7)g = 1 1/2
g = (1 1/2)/(5/7) . . . . division expression for the paint needed

If a 18 ft tall tree casts a 9 ft long shadow
then how tall is an adult giraffe standing near it that casts a 7
ft shadow?
Answer:
[tex] \boxed{ \tt{the \: adult \: giraffe \: is \to \: 14 \: ft}}[/tex]
The height of the giraffe standing near it which casts a shadow of 7 feet is 14 feet.
What is Scale Factor?Scale factor is the ratio of the dimension of the given original object and the dimension of the new object from the original.
Given that,
Actual height of the tree = 18 feet
Height of the shadow = 9 feet
Actual height = 2 × Shadow height
So, here the scale factor is 2.
Given Shadow height of the giraffe = 7 feet
Actual height of the giraffe = 2 × height of shadow of the giraffe
= 2 × 7 feet
= 14 feet
Hence the height of the giraffe is 14 feet.

Answer:
y = 2x + 8
Step-by-step explanation:
Recall that two parallel lines have the same slope.
Thus, if we begin with y = 2x - 4, we know that this new line through (-1, 6) will also have slope 2.
Starting from the slope-intercept form y = mx + b, we substitute 2 for m, -1 for x and 6 for y:
6 = 2(-1) + b
and solve for the new y-intercept, b:
6 = -2 + b, or
b = 8
Then the new line has the equation y = 2x + 8
