Answer:
16 times
Step-by-step explanation:
This problem is solved by ratio. Since the ratio of 28 out of 25 times is 4:5, he has to catch the ball 4:5 or 4 of 5 times. You multiply both 5 and 4 by 4, because that's how many times he's gonna catch it. 4 x 4 = 16, so the answer is 16 times.
Answer:
(4/5)^20
Step-by-step explanation:
1) First, write the numbers of times Raymond caught the football out of 35 attempts. This is a necessary step in order to obtain an appropriate operand.
28
35
2) Reduce the fraction to lowest terms. This is an optional step but it simplifies the problem.
28 / 4
35 4
= 4
5
3) Raise the fraction to the 20th power. If the ball is thrown at him 20 times, the probability of him successfully catching the ball must be (4/5)^20.
= (4)^2

Answer:
1,000 mm³
Step-by-step explanation:
To find the volume we use the formula:
V = L×W×H (L=length, W=width and H=height)
Since we are given all values we substitute the values to give us:
V= 10×10×10 = 1000
Units will be mm³ as this is volume.

if it's area, it's the first one
5 How many balls can Brad put in a box that has 6 x 6 balls in the bottom layer and 5
layers? Show your work.
A product is the outcome of multiplication. Brad can put 144 balls in the box.
What is multiplication?A product is the outcome of multiplication or an expression that indicates the elements that will be multiplied.
Given that the bottom layer of the box has 6×6 balls, while the box has 5 layers. Since one layer is already arranged, therefore, there are only 4 layers left in which each layer will have 6×6 balls. Therefore, the total number of balls is,
[tex]\text{Total number of ball} = 4 \times 6\times 6 = 144[/tex]
Hence, Brad can put 144 balls in the box.

Answer:
∠DBC = 155°
Step-by-step explanation:
Assuming that ABC is a straight line.
Angles on a straight line sum to 180°.
⇒ (2x² + 3x - 2) + ∠DBC = 180°
⇒ ∠DBC = 180° - (2x² + 3x - 2)
The sum of the interior angles of a triangle is 180°:
⇒ (x² + 1) + (4x + 3) + ∠DBC = 180°
⇒ ∠DBC = 180° - (x² + 1) - (4x + 3)
Therefore, we can equate the equations and solve for x:
⇒ ∠DBC = ∠DBC
⇒ 180 - (2x² + 3x - 2) = 180 - (x² + 1) - (4x + 3)
⇒ 180 - 180 = (2x² + 3x - 2) - (x² + 1) - (4x + 3)
⇒ (2x² + 3x - 2) - (x² + 1) - (4x + 3) = 0
⇒ 2x² + 3x - 2 - x² - 1 - 4x - 3 = 0
⇒ x² - x - 6 = 0
⇒ x² + 2x - 3x - 6 = 0
⇒ x(x + 2) - 3(x + 2) = 0
⇒ (x + 2)(x - 3) = 0
Therefore, x = -2, x = 3
As angles are positive, x = 3 only
Substituting found value of x into the angle expressions:
⇒ ∠BDC = x² + 1 = (3)² + 1 = 10°
⇒ ∠DCB = 4x + 3 = 4(3) + 3 = 15°
The sum of the interior angles of a triangle is 180°:
⇒ ∠DBC + ∠BDC + ∠DCB = 180°
⇒ ∠DBC = 180° - ∠BDC - ∠DCB
⇒ ∠DBC = 180° - 10° - 15°
⇒ ∠DBC = 155°

A diesel train left Bangalore and traveled west at an average speed
of 59 km/h. A freight train left at the same time and traveled in the
opposite direction with an average speed of 67 km/h. Find the number of
hours the freight train needs to travel before the trains are 1008 km
apart.
Answer:
8
Step-by-step explanation:
we'll make x the number of hours and set up the following equation:
59km x + 67km x = 1008km
Now we solve for x(hours)
126x = 1008
x = 8

Please help! Area of part of a circle!!!
The sector (shaded segment + triangle) makes up 1/3 of the circle (which is evident from the fact that the labeled arc measures 120° and a full circle measures 360°). The circle has radius 96 cm, so its total area is π (96 cm)² = 9216π cm². The area of the sector is then 1/3 • 9216π cm² = 3072π cm².
The triangle is isosceles since two of its legs coincide with the radius of the circle, and the angle between these sides measures 120°, same as the arc it subtends. If b is the length of the third side in the triangle, then by the law of cosines
b² = 2 • (96 cm)² - 2 (96 cm)² cos(120°) ⇒ b = 96√3 cm
Call b the base of this triangle.
The vertex angle is 120°, so the other two angles have measure θ such that
120° + 2θ = 180°
since the interior angles of any triangle sum to 180°. Solve for θ :
2θ = 60°
θ = 30°
Draw an altitude for the triangle that connects the vertex to the base. This cuts the triangle into two smaller right triangles. Let h be the height of all these triangles. Using some trig, we find
tan(30°) = h / (b/2) ⇒ h = 48 cm
Then the area of the triangle is
1/2 bh = 1/2 • (96√3 cm) • (48 cm) = 2304√3 cm²
and the area of the shaded segment is the difference between the area of the sector and the area of the triangle:
3072π cm² - 2304√3 cm² ≈ 5660.3 cm²

PLEASE HELPP I GIVE OUT MORE POINTS AND BRAINIST ONLY IF YOUR RIGHT THO I DO CHECK IT PLEASE AND THANK YOU !!
Answer:
Domain: 0 ≤ x ≤ 4
Range: 0 ≤ y ≤ 64
Step-by-step explanation:
Information
Domain: set of all possible input values (x-values)
Range: set of all possible output values (y-values)
From inspection of the diagram, the minimum value of x is 0 and the maximum value of x is 4.
Therefore, the domain is: 0 ≤ x ≤ 4
From inspection of the diagram, the minimum value of y is 0 and the maximum value of y is 64.
Therefore, the range is: 0 ≤ y ≤ 64
Remember:-
If a pair be (x,y) then
x is domainy is rangehence
Here x goes from 0 to 4 so domain is
[0,4]Y goes from 0 to 64 hence range is

Answer:
| Drink (x ml) | 200 | 100 | 500| 1000|
| Sugar (y g) | 20 | 10 | 50 | 100 |
Step-by-step explanation:
Formula : y=k/x
Solve:
Before we find the answer chart =
| Drink (x ml) | 200 | 100 | 500| 1000|
| Sugar (y g) | 20 | ? | ? | ? |
20 = ? / 200
? = 10
Thus,
100/10 = 10
500/10 = 50
1000/10 = 100
So the chart now is:
| Drink (x ml) | 200 | 100 | 500| 1000|
| Sugar (y g) | 20 | 10 | 50 | 100 |

Edward opens up a savings account with $250. The bank gives him an interest rate of 2.8% per year (simple interest). About long will it take for Edward to double his money?
(SHOW WORK!!)
Equation:________________
Answer:_________________
Step-by-step explanation:
The interest I per t years is 2.8% of invested amount P
I = PrtLet the interest amount is same as invested amount, then our equation is
P = Prt or1 = rt or1 = 0.028t 2.8% converted to 0.0028Find the value of t
t = 1/0.028t = 35.71 or roughly 36 yearsAnswer:
Equation: 250(1 + 0.028t) = 500
Answer: 36 years
Step-by-step explanation:
Simple interest formula
A = P(1 + rt)
where:
A = final amountP = principalr = interest rate (in decimal form)t = time (in years)Given:
A = double $250 = $500P = $250r = 2.8% = 0.028Substitute given values into the formula and solve for t:
250(1 + 0.028t) = 500
⇒ 250 +7t = 500
⇒ 7t = 250
⇒ t = 250/7
⇒ t = 35.71428571...
So it will take approximately 36 years for Edward to double his money.
