4. What does the y-intercept of the graph of Monday's storm mean? Does the y-intercept of the graph of Thursday's storm have the same meaning?
Answer/Step-by-step explanation:
✅The y-intercept of the graph of Monday's storm is the amount of precipitation recorded at the beginning of the tracking or when the tracking started.
✍️The y-intercept of the graph of Monday's storm is 0 mm, when time = 0 min.
✅The y-intercept of the graph of Thursday's storm also has the same meaning as that of Monday's storm.
✍️The y-intercept of the graph of Thursday's storm is 0 mm, when time = 0 min.
solve for the unknown.
4^2x+3=1
what does x equal?
Answer:
x = -1/8
Step-by-step explanation:
4^2x + 3 = 1 start by simplifying the equation
16x + 3 = 1 now subtract 3 on both sides
16x = -2 isolate the variable by dividing 16 on both sides
x = -1/8
Answer:
x = -1/8
Step-by-step explanation:
4^2x + 3 = 1
You want to try to get the x on one side by itself.
First step subtract 3 from both sides
4^2x + 3 -3 = 1 -3
so now it looks like 4^2x = -2
We know 4^2 is 4x4 which is 16.
16x= -2
Divide 16 by both sides.
x = -2 / 16
Reduce.
x = -1/8

Nika baked three loaves of zucchini bread. Each loaf needed StartFraction 17 over 4 EndFraction cups of flour. Which expression shows the best estimate of the number of cups of flour that Nika used? 4 + 4 + 4 = 12 5 + 5 + 5 = 15 4 + 4 + 4 = 16 17 + 17 + 17 = 51
Answer:
4+4+4=12
Step-by-step explanation:
Each cake needs cups of flour. Therefore, the best estimate of the number of cups of flour that Nika used to make the three loaves is:
4 + 4 + 4 = 12
Answer:
Step-by-step explanation:
Nika baked three loaves of zucchini bread.
Each bread needed 17/4
17/4 simplified as a decimal is 4.25 or as a fraction 4/25
Answer 3
4 + 4 + 4 = 16
Why? Because 4/25 is NOT gonna be a whole number.
25/25 = 1.
So, saying that I picked the 3rd answer because 16 is closer to 25.
16 is over 4 so we have to look at the next place value. And 51 is more than 25.
One day, Farmer Brown counts his chickens and his
eggs. He finds the ratio of chickens to eggs is 7 to 12. If
there are 77 chickens, how many eggs are there?
Answer:
132 eggs
Step-by-step explanation:
7 chickens to 12 eggs; 77 chickens to x eggs
7/12 to 77/x
77/7 = 11
7/12 (11/11)
77/132
77 chickens to 132 eggs
If there are 77 chickens, and the ratio of chickens to eggs is 7 to 12, there are 132 eggs.
The number of eggs from the given ratio are 132.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, the ratio of chickens to eggs is 7 to 12.
There are 77 chickens.
Let x be the total number of chickens and eggs.
Now, 7/19 ×x=77
⇒ 7x=1463
⇒ x=209
Number of eggs =209-77
= 132
Therefore, the number of eggs are 132.

US basketball legend Kobe Bryant and his daughter Gianna were among nine people killed in a helicopter crash in the city of Calabasas, California.

Suppose the owner of a local apple orchard has 4 half-bushels of apples to sell. He loads them on his truck, and drives his route, stopping at stores along the way attempting to sells the apples. Suppose:
- Each half-bushel is sold for $40.
- It will cost $15 of gas to drive the route.
Historically, the orchard owner knows he will have a 40% chance of making no sales, a 30% chance of selling 1 half-bushel, a 10% chance of selling 2 half-bushels, and a 10% chance of selling 3 half-bushels.
(a) Calculate the orchard owner’s expected profit from driving the route.
(b) Calculate the standard deviation of the profit from driving the route.
Answer:
a) The orchard owner's expected profit from driving the route is $33.
b) The standard deviation of the profit is $27.28
Step-by-step explanation:
a) Data and Calculations:
Apples to sell = 4 half-bushels
Price of each half-bushel sold = $40
Sales revenue = $160 ($40 *4)
Cost of driving the route = $15
Expected values:
Event Probability Revenue Profit Expected Profit
No Sales 40% $0 ($15) ($0 - $15) ($6.00)
Selling 1 half-bushel 30% $40 $25 ($40 - $15) $7.50
Selling 2 half-bushels 10% $80 $65 ($80 - $15) $6.50
Selling 3 half-bushels 10% $120 $105 ($120 - $15) $10.50
Selling 4 half-bushels 10% $160 $145 ($160 - $15) $14.50
Total expected profit = $33
Event Expected Profit Mean Squared
Difference
No Sales ($6.00) -39 1,521
Selling 1 half-bushel $7.50 -25.5 650.25
Selling 2 half-bushels $6.50 -26.5 702.25
Selling 3 half-bushels $10.50 -22.50 506.25
Selling 4 half-bushels $14.50 -18.50 342.25
Sum of squared differences 3,722
Mean of squared differences = 744.4 (3,722/5)
Standard deviation = square root of the mean
= 27.28
= $27.28

A truck with 30-inch diameter wheels is traveling at 70 mi/h. Find the angular speed of the wheels in radians per minute. ___ radians per minute How many revolutions per minute do the wheels make? (Round your answer to three decimal places.) ____ revolutions per minute
truck with 30-in.-diameter wheels is traveling at 70 mi/h.
---------
1 mile per hour = 88 feet per minute
70 mi/hr = 6160ft/minute
----------
Each revolution = pi*d feet = 4pi feet
(b) How many revolutions per minute do the wheels make?
rev/min
-------------
Each revolution = pi*d feet = 4pi feet
rpm = 6160 ft/min / 4pi feet = 990/pi rpm
=~ 1540 rpm
---------------
(a) Find the angular speed of the wheels in rad/min.
rad/min
-------------
rad/min = rpm*2*pi
= 1540 rpm × 2× π
= 9676.1053731 rad/min

Cindy is selling circus tickets. On the first day she sells 6 adult tickets and 5 children tickets for total of 112.50. On the second day she sells 8 adult tickets and 4 children tickets for the total 130. Determine the cost of adult and child tickets. Used a to represent adult and c to represent child tickets. Write an equation to represent the sales of day 1 and day 2. Used the elimination method.
Answer: Children tickets cost 7.50
Adult tickets cost 12.50
Step-by-step explanation:
Let a represent adult tickets
Let c represent child tickets
On the first day she sells 6 adult tickets and 5 children tickets for total of 112.50. This can be written as:
6a + 5c = 112.50 ...... equation i
On the second day she sells 8 adult tickets and 4 children tickets for the total 130. This can be written as:
8a + 4c = 130 ....... equation ii
6a + 5c = 112.50 ...... equation i
8a + 4c = 130 ....... equation ii
Multiply equation i by 4
Multiply equation ii by 5
24a + 20c = 450 ........ equation iii
40a + 20c = 650 ......... equation iv
Subtract iii from iv
16a = 200
a = 200/16
a = 12.50
Adult tickets cost 12.50
From equation ii,
8a + 4c = 130
8(12.50) + 4c = 130
100 + 4c = 130
4c = 130 - 100
4c = 30
c = 30/4
c = 7.50
Children tickets cost 7.50
Using the concept of elimination, the cost of adult and children tickets are $12.5 and $7.5 respectively
Let :
Number of adult tickets = a Number of children's tickets = cCreating a system of equation thus :
6a + 5c = 112.50 - - - (1)
8a + 4c = 130 - - - - (2)
Multiply (1) by 4 and (2) by 5
24a + 20c = 450 - - - - (3)
40a + 20c = 650 - - - - (4)
Subtract
-16a = - 200
Divide both sides by - 16
a = 12.5
From (2) :
8(12.5) + 4c = 130
100 + 4c = 130
4c = 130 - 100
4c = 30
c = 7.5
Hence, the cost of adult and children tickets are $12.5 and $7.5

A circle has a radius of 13cm . Find the radian measure of the central angle 0 that intercepts an arc of length8cm . Do not round any intermediate computations, and round your answer to the nearest tenth.
Answer:
The measure of the center angle is 0.6 radians
Step-by-step explanation:
Mathematically, the length of an arc can be calculated using;
L = theta/360 * 2 * pi * r
where theta is the central angle
In this case, theta = ? , pi = 22/7 and r is 13
cm, length of arc is 8 cm
So we have ;
8 = theta/360 * 2 * pi * 13
360 * 7 * 8 = theta * 2 * 22 * 13
20,160 = 572 theta
theta = 20,160/572
theta = 35.24
let us convert this to radian measure
Mathematically, 1 degree = 0.0175 radian
Thus 35.24 degrees will be 35.24 * 0.0175 = 0.62 radians
To the nearest tenth, this is 0.6 radians
A right-angled triangle has one side of length 1.5 cm. Its hypotenuse is 6 cm. How long is its other side?
Answer:
about 5.8cm
Step-by-step explanation:
write "yes" or "no" to state whether or not the given side lengths would form a right triangle.
25, 16, 12
A) Yes
B No
Answer: No
Step-by-step explanation:
To find out if it is a right triangle then use the formula a^2 + b^2 = c^2 where a and b are the legs which are the two small sides and c is the hypotenuse the longest side. Input the values for a, b, and c and solve.
a = 12
b = 16
c= 25
12^2 + 16^2 = 25^2
144 + 256 = 625
400 = 625
This means that it is not a right angle because 400 does not equal to 625.
