Jami is keeping track of the weather for a class project she recorded data on 16 days out of 16 days 1/4 were clear blue skies how many days had clear blue skies
Answer:
4 days
Step-by-step explanation:
She recorded date for 16 days, and 1/4 of the days were clear blue skies.
One way to find this is to multiply 16 and 1/4
16*1/4=4
Another way is to first convert 1/4 to a decimal
1/4=0.25
Then multiply 16 and 0.25
16*0.25 =4
So, 4 out of 16 days had clear blue skies

Mrs. Wilton is planning a rectangular flower box for her front window. She wants the flower box to hold exactly 16 cubic feet of soil.How many flower boxes with different-size bases will hold exactly 16 cubic feet of soil, using whole-number dimensions?flower boxes with different-size bases will hold exactly 16 cubic feet of soil. please no fake answers or you not getting nothing
There are 4 different flower boxes with different-size bases that can hold exactly 16 cubic feet of soil when using whole-number dimensions. These consist of dimension combinations of 1x1x16, 1x2x8, 1x4x4, and 2x2x4 feet.
Mrs. Wilton is planning a rectangular flower box that should have a volume of 16 cubic feet. To find how many flower boxes with different-size bases can hold exactly 16 cubic feet of soil, we need to find all the possible combinations of whole-number dimensions (length, width, and height) that when multiplied together equal 16 cubic feet. We must remember that volume is calculated as Length x Width x Height. Since 16 is the volume in cubic feet, we look for whole-number factors of 16.
Here are the possible whole-number dimension sets (in feet) for a volume of 16 cubic feet:
1 x 1 x 16 (Height can be 1, 16, or any factor of 16)
1 x 2 x 8 (Height can be 2, 8, or any factor of 16)
1 x 4 x 4 (Height can be 4 or any factor of 16)
2 x 2 x 4 (These dimensions are interchangeable)
Each of these dimensions gives a different base size for the flower box, and all ensure the volume is 16 cubic feet. Thus, there are 4 different flower boxes with different-size bases that will hold exactly 16 cubic feet of soil.

Answer:
What is your exact question?
Step-by-step explanation:
Explanation:
The notation [tex]A \cap B[/tex] means "the overlapped region between circles A and B". There is only one value in this region, and it is the "8". This is in the lower half of this region as the upper half is empty.
There are 12 values in the set {2,4,6,8,10,12,14,16,18,20,24} which we can see by counting them out, or we can note how 24 = 2*12 and how we started with 2 = 2*1. So basically we have...
2 = 2*14 = 2*26 = 2*38 = 2*410 = 2*512 = 2*614 = 2*716 = 2*818 = 2*920 = 2*1022 = 2*1124 = 2*12So again we have 1 value in the overlapped region between A and B, out of 12 values total. So that's why the answer is 1/12.
9. Betsy's softball team won 47 games, lost
15 games, and tied none. What fractional
part of the games played did the team
win?
Answer:
47/62
Step-by-step explanation:
62 total games won 47 therefore 47/62
Final answer:
The fractional part of the games won by Betsy's softball team is 47/62, representing the number of games won out of the total games played.
Explanation:
To calculate the fractional part of the games won by Betsy's softball team, you need to divide the number of games won by the total number of games played. The team won 47 games and lost 15 games, giving a total of 47 + 15 = 62 games played.
The fraction representing the part of the games won is therefore 47/62. When simplified, this fraction may be reduced to a simpler form by finding the greatest common divisor and dividing both the numerator and the denominator by it. However, as 47 is a prime number and does not divide evenly into 62, the fraction can't be simplified further. Therefore, the fractional part of the games won by the team is 47/62.
Which point is the center of the circle defined by the equation 2+(−9)2=81 x 2 + ( y − 9 ) 2 = 81 2+(−9)2=81 x 2 + ( y − 9 ) 2 = 81 Group of answer choices (0, -9) (-9, 0) (0, 9) (9, 0)
Answer:
(0, 9)
Step-by-step explanation:
The circle defined by the equation ...
(x -h)^2 +(y -k)^2 = r^2
has its center at (h, k).
We think your circle's equation is ...
x^2 + ( y − 9 )^2 = 81
so it would have its center where h = 0 and k = 9.
The center is (0, 9).

A race is 9/10 kilometers long. Lamar ran 2 of these races . How far did he run together?
Answer:
1.8
Step-by-step explanation:
9/10 times 2 equals 1.8
/Answer:
The answer would be 18/10.
Step-by-step explanation:
This is because when you add fractions with common denominators, like 9/10+9/10, you don't add the denominators. But if you multiply 9/10*2 it would be like 9/10*2/1 which would equal 18/10 still.
A 92.0 kg football player at 6.50 m/s North collides with an 85.0 kg football player running at 6.00 m/s south. The 92.0 kg football player continues moving at a velocity of 2.00 m/s after the collision. What is the velocity of the 85.0 kg football player after the collision?
Answer:
-1.13 m/s
Step-by-step explanation:
Parameters given:
Mass of first footballer, M = 92 kg
Initial velocity of first footballer, U = 6.5 m/s (taking North to be the +ve y axis)
Mass of second footballer, m = 85 kg
Initial velocity of second footballer, u = -6.0 m/s (taking South to be the -ve y axis)
Final velocity of first footballer, V = 2.0 m/s
We need to find the final velocity of the second football (v)
Applying the principle of conservation of momentum, we have that, in a system:
Total Initial Momentum = Total Final Momentum
(M * U) + (m * u) = (M * V) + (m * v)
(92 * 6.5) + (85 * -6) = (92 * 2) + (85 * v)
598 - 510 = 184 + 85v
88 = 184 + 85v
88 - 184 = 85v
-96 = 85v
=> v = -96 / 85
v = -1.13 m/s
The final velocity of the 85 kg player is -1.13 m/s i.e 1.13 m/s South
Final answer:
To find the unknown velocity of the 85.0 kg football player after the collision, we use the conservation of momentum, setting up an equation based on the initial and final momenta of both players and solving for the unknown velocity.
Explanation:
The question concerns the topic of conservation of momentum during a collision between two football players, which falls under the category of Physics. To solve for the velocity of the 85.0 kg football player after the collision, we can use the principle that the total momentum before the collision is equal to the total momentum after the collision in an isolated system.
The total momentum before the collision can be calculated as follows:
Momentum of the 92.0 kg player = mass × velocity = 92.0 kg × 6.50 m/s (North).
Momentum of the 85.0 kg player = mass × velocity = 85.0 kg × 6.00 m/s (South).
Since they are moving in opposite directions, we assign a positive direction (e.g., north) as positive momentum and the opposite direction (south) as negative momentum.
The total momentum after the collision consists of:
Momentum of the 92.0 kg player = 92.0 kg × 2.00 m/s (North).
Momentum of the 85.0 kg player = 85.0 kg × v (where v is the unknown velocity).
By applying the conservation of momentum, we can write the equation:
(92.0 kg × 6.50 m/s) + (85.0 kg × -6.00 m/s) = (92.0 kg × 2.00 m/s) + (85.0 kg × v).
Solving for v gives:
v = [(92.0 kg × 6.50 m/s) - (92.0 kg × 2.00 m/s) - (85.0 kg × -6.00 m/s)] / 85.0 kg.
Calculate the value to find the final velocity of the 85.0 kg player.
v = 10.87 m/s

A gym charges a $615 yearly fee for membership plus $50 for each hour of personal training. What is the average total cost per hour of training if a member works with a personal trainer for 30 hours in a year? Do not include the dollar sign ($) in your answer.
Answer:
The average total cost per hour of training is $70.5
Step-by-step explanation:
The form of the linear function is f(x) = m x + b, where
m is the average rateb is the initial value∵ The gym charges a $615 yearly fee for membership plus
$50 for each hour of personal training
- That means the initial amount is 615 and the average rate is 50
∴ m = 50 dollars per hour
∴ b = 615 ⇒ fixed fee
- Substitute m and b in the form of the linear function
∴ c(x) = 50 x + 615, where c(x) is the cost per year for x
training hours
∵ A member works with a personal trainer for 30 hours in a year
- That means x = 30
∴ x = 30
- Find the total cost of this year by substituting x by 30
∴ c(30) = 50(30) + 615
∴ c(30) = 1500 + 615
∴ c(30) = 2115
∴ The total cost of this year is $2115
To find the average cost per hour divide the total cost by the number of the training hours
∵ Average cost per hour = 2115 ÷ 30
∴ The average cost per hour = 70.5 dollars
∴ The average total cost per hour of training is $70.5
Based on the number of hours and the cost per hour of using the trainer, the average cost per hour is $70.50 per hour.
First find the total cost of using a trainer for 30 hours.
= Fixed membership cost + (Cost per hour x Number of hours)
= 615 + (50 x 30)
= $2,115
The total cost for the year is $2,115.
The average cost per hour will be:
= Total cost / Number of hours
= 2,115 / 30
= $70.50
In conclusion, the total average cost per hour is $70.50.

sin Ф = 1/5
cos Ф = ?
To solve this problem use trigonometric functions.
1.- The first condition is that the angle must be in the first quadrangle
(0° < Ф < 90°).
2.- Write the trigonometric function sine.
sin Ф = Opposite side / hypotenuse and sin Ф = 1/5
then, Opposite side = 1 hypotenuse = 5
3.- Use the Pythagorean theorem to find the adjacent side.
Hypotenuse² = Opposite side² + Adjacent side²
-Solve for Adjacent side
Adjacent side² = Hypotenuse² - Opposite sie²
-Substitution
Adjacent side² = 5² - 1²
-Simplification
Adjacent side² = 25 - 1
Adjacent side ² = 24
Adjacent side = √24
4.- Find the cosФ
cos Ф = Adjacent side/hypotenuse
-Substitution
cosФ = √24 / 5
"Lashonda swam 4 kilometers against the current in the same amount of time it took her to swim 16 kilometers with the current. The rate of the current was 3 kilometers per hour. How fast would Lashonda swim if there were no current?"
Answer:
5 km/h
Step-by-step explanation:
In this problem, Lashonda swam 4 km against the current. So the distance covered in this case is
[tex]d_1=4 km[/tex]
Calling [tex]v[/tex] the velocity of Lahonda without the current, and [tex]c[/tex] the velocity of the current, in this situation Lahonda's velocity is
[tex]v-c[/tex]
So we can write:
[tex]t_1=\frac{d_1}{v-c}[/tex]
where [tex]t_1[/tex] is the time taken to cover the distance.
When Lashonda swims with the current, her velocity is
[tex]v+c[/tex]
So we can write
[tex]t_2=\frac{d_2}{v+c}[/tex]
where
[tex]d_2=16 km[/tex] is the distance covered in this case, and [tex]t_2[/tex] the time taken.
The velocity of the current is
[tex]c=3 km/h[/tex]
Since Lashonad takes the same time to cover the two distances,
[tex]t_1=t_2[/tex]
So we can write
[tex]\frac{d_1}{v-c}=\frac{d_2}{v+c}[/tex]
And solving for v, we find Lashonda's velocity without the current:
[tex]d_1(v+c)=d_2(v-c)\\d_1 v+d_1c = d_2v-d_2c\\v(d_2-d_1)=c(d_1+d_2)\\v=\frac{d_2+d_2}{d_2-d_1}c=\frac{16+4}{16-4}(3)=5 km/h[/tex]
Final answer:
To find Lashonda's swimming speed without the current given the rate of the current and the distances swam with and against it.
Explanation:
The rate of the current is 3 kilometers per hour. To find the speed of Lashonda without the current, we can set up equations using the formula: speed = distance/time.
Let's denote Lashonda's speed in still water as x kilometers per hour. When swimming against the current, her effective speed is x - 3 km/h, and when swimming with the current, her effective speed is x + 3 km/h.
By setting up and solving the equations, we find Lashonda's speed without the current is 9 kilometers per hour.

Angle 4 is congruent to Angle 2 because they are alternate interior angles formed by the transversal intersecting two parallel lines.
Given that lines k and l are parallel, and lines m and n intersect to form two triangles, we need to determine which angle is congruent to Angle 4.From geometry, we know that alternate interior angles are congruent when two parallel lines are cut by a transversal. Here, lines m and n intersecting parallel lines k and l can be visualized as forming such alternate interior angles.Since Angle 4 is within the lower triangle, the angle in the upper triangle that is on the 'opposite' side of the transversal, corresponding to the same spot, is Angle 2.Congruence of Angles

The rectangle below has an area of 81-x^2 square meters and a width of 9-x meters. What expression represents the length of the rectangle?
For this case we have that by definition, the area of a rectangle is given by:
[tex]A = w * l[/tex]
Where:
w: Is the width of the rectangle
l: is the length of the rectangle
According to the data of the statement we have:
[tex]A = 81-x ^ 2\\w = 9-x[/tex]
So, the length is given by:
[tex]l = \frac {A} {w}\\l = \frac {81-x ^ 2} {9-x}[/tex]
