How tall would the building be
Answer:
18
Step-by-step explanation:
1. Create the ratio 12:9
The first number in the ratio is where the length of the shadow will go. The second number is where the length of the building will go.
2. Subtract 21 by 12 to find out how much we have to add to 9. (21-12=9)
3. Add 9 to 9. (18)
We now have 21:18.

What plus 32 equals 98
Answer:
66
Step-by-step explanation:
Answer:
Lets numeralise the question,
According to question 32+ ? = 98
So if we take the unknown value as x then we will get,
32+x=98
So by transposing we get,
x=98-32
= 66
So 66 should be added to 32 to get 98

12.) Given the following information, determine which lines, if any, are parallel. State the converse that justifies your answer. Pleaseee helppp
Answer:
Step-by-step explanation:
Given Parallel lines Converse
a. ∠13 ≅ ∠17 a║c Corresponding angles
b. ∠4 ≅ ∠9 d║e Exterior alternate angles
c. m∠20 + m∠21 = 180° a║b Consecutive interior angles
d. ∠8 ≅ ∠19 Vertical angles
e. ∠10 ≅ ∠23 b║c Interior alternate angles
f. m∠14 + m∠17 = 180° a║c Consecutive interior angles
From the given diagram and information, it can be concluded that lines a, b, and c are parallel, and lines d and e are parallel.
The given lines in the diagram are a, b, c, d, and e.
a. It is given that the measure of angle 13 is equal to that of angle 17.
Now, these two angles are made by lines a, c, and d. Now, the angles are corresponding and equal, and hence, lines a and c will be parallel.
b. It is given that the measure of angle 4 is equal to that of angle 9.
These two angles are made by lines d, e, and b. Now, the angles are alternate exterior and equal, and hence, lines d and e will be parallel.
c. It is given that the sum of the measure of angles 20 and 21 is equal to 180 degrees.
These two angles are made by lines a, b, and e. Now, the angles are supplementary and their sum is 180 degrees, and hence, lines a and b will be parallel.
d. It is given that the measure of angle 8 is equal to that of angle 19.
These two angles are vertically opposite angles between lines a and e.
e. It is given that the measure of angle 10 is equal to that of angle 23.
These two angles are made by lines b, c, and e. Now, the angles are alternate interior and equal, and hence, lines b and c will be parallel.
f. It is given that the sum of the measure of angles 14 and 17 is equal to 180 degrees.
These two angles are made by lines a, c, and d. Now, the angles are supplementary and their sum is 180 degrees, and hence, lines a and c will be parallel.
Therefore, it can be concluded that lines a, b, and c are parallel, and the lines d and e are parallel.

Find the directions in which the function increases and decreases most rapidly at P0. Then find the derivatives of the function in those directions.
Answer and Step-by-step explanation:
SOLUTION:
Given function:
h (x, y, z) = ln (x2 + y2 – 1) + y +6z, p0(1, 1, 0)
Derivatives of the function:
∂h / ∂x = (1 / x2 + y2 -1). (2x)
= 2x / x2 + y2 -1
∂h/∂y = (1 / x2 + y2 – 1) (2y + 1)
= (2y / x2 + y2 -1) + 1
∂h / ∂z = 6
Now compute the partial derivatives:
∂h (1, 1, 0) / ∂x = 2(1) / 1 +1 -1
= 2
∂h(1, 1, 0) / ∂y =( 2(1) / 1 +1 -1) + 1
= 3
∂h (1, 1, 0) / ∂z = 6
Δh (1,1,0) = ( 2, 3, 6)
The definition of gradient is:
Δf (x, y, z) = (∂f / ∂x , ∂f / ∂y)
Put the coordinate values to arrive at solution:
Umax = Δh (1,1,0) / | Δh (1,1,0) |
= (2, 3, 6) / |2, 3, 6|
= (2, 3, 6) / √(22+33+62)
= (2, 3, 6) / √49
= (2, 3, 6) / 7
= (2/7 , 3/7, 6/7)
Umin = - U max = ( -2/7, -3/7, -6/7)
Compute direction by finding unit vector:
Du h max = Δh (1,1,0) . u max
= (2, 3, 6) . (2/7, 3/7, 6/7)
= 2(2/7) + 3(3/7) + 6(6/7)
= 4/7 + 9/7 +36/ 7
= 49 / 7
= 7
Du h min = -Du h max
= -7

A bag contains 3 red marbles, 8 blue marbles and 7 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be green?
Answer:
A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.
Total = 18 marbles.
Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.
Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.

Suppose there is a 3.1 temperature drop for every thousand feet that an airplane climbs
into the sky. If the temperature on the ground is 60.1, what will the temperature be
when the plane reaches an altitude of 11,000 feet?
Answer:
34.1 degrees
Step-by-step explanation:
given that the temperature drops 3.1 degrees for every thousand feet of elevation.
for an altitude of 11,000 feet (i.e 11 x 1000 feet), the temperature (compared to ground level) would drop,
= 3.1 deg / 1000-foot x 11,000 feet
= 34.1 degrees

find the standard deviation
Answer:
d. 7.3
Step-by-step explanation:
To get the standard deviation of a population of data, first take the sum of all the values, and divide it by the count to get the mean (average).
75 [1] + 90 [2] + 75 [3] + 80 [4] + 90 [5] + 80 [6] + 100 [7] + 85 [8] + 80 [9] + 85 [10] = 840.
Then divide by the count which is 10.
840/10 = 84 [This is the mean of the data.]
Then subtract every point of data from the mean and square it:
(75-84)^2 + (90-84)^2 + (75-84)^2 + (80-84)^2 + (90-84)^2 + (80-84)^2 + (100-84)^2 + (85-84)^2 + (80-84)^2 + (85-84)^2 = 81 + 36 + 81 + 16 + 36 + 16 + 256 + 1 + 16 + 1 = 540.
Then to get the variance, divide this all by the count.
540/10 = 54 [This is the variance of the data.]
Then all you have to do to get the standard deviation is take the square root of the variance.
√54 = 3√6 ≈ 7.3 [This is the standard deviation of the data.]
6{[(600x10²)]} - [(3x5)x2]+5-10+2=
Answer:
359967
Step-by-step explanation:
6{[(600 x 10²)]} - [(3 x 5) x 2] + 5 - 10 + 2 =
= 6(600 x 100) - [15 x 2] - 5 + 2
= 6(60000) - 30 - 5 + 2
= 360000 - 35 + 2
= 359965 + 2
= 359967
Sohie’s mom cans jelly. She fills each jar with 1/2 a pint of jelly. If she made 1 7/10 pints of jelly, which expression can be used to find how many jars Sophie’s mom can fill?
Answer:
Number of jar Sohie's mom can make can be found out by dividing the total amount by the amount in one jar, so we can frame a equation like this,
Let the number of total jar be x,
x = (1 7/10) / 1/2
That is the answer, let us solve this equation,
x = 1 7/10 / 1/2
=> x = 17/10 * 2/1
=> x = 17/5 * 1/1
=> x = 17/5
17/5 = 3.40
Therefore, she can pack 3.4 jars of jelly.
If my answer helped, please mark me as the brainliest!!
Thank You!!
