Answer:
4, 5 and 27.
Step-by-step explanation:
There are 2 cube numbers between 0 and 36 .
They are 8 and 27.
36 - 27 = 9 so the other 2 numbers could be 4 and 5 because they are both factors of 20.
36 - 8 = 28 whose factors are 2 * 2 * 7 which are not factors of 20.
GEOMETRY HELP WILL MARK BRAINLIEST
Answer:
6² + x² = 10²
36 + x² = 100
36 - 36 + x² = 100 - 36
x² = 64
√x² = √64
x = 8
Step-by-step explanation:
Answer:
[tex]x = 8[/tex]
Step-by-step explanation:
According to PYTHAGORAS theorem
[tex] {6}^{2} + {x}^{2} = {10}^{2} \\ 36 + {x}^{2} = 100 \\ {x}^{2} = 100 - 36 \\ {x}^{2} = 64 \\ x = \sqrt{64} \\ x = 8[/tex]

A dolphin is swimming at a constant speed. It travels 30 meters every 5 seconds. What is the slope of the line that shows the relationship between x, time in seconds, and y, the distance in meters traveled by the dolphin
Answer:
6 meters per 1 second or 6m/s
Step-by-step explanation:
slope is rise/run or change in y/change in x
in this case y=30, x=5 so slope = 30/5= 6
A diver dives from the board at a local swimming pool. Her height, y, in metres, above the water in terms of her horizontal distance, x, in metres, from the end of the board is given by y= -x^2 + 2x + 3. What is the diver's maximum height?
Answer:
4 meters
Step-by-step explanation:
Given a quadratic equation in which the coefficient of [tex]x^2[/tex] is negative, the parabola opens up and has a maximum point. This maximum point occurs at the line of symmetry.
Since the divers height, y is modeled by the equation
[tex]y= -x^2 + 2x + 3[/tex]
Step 1: Determine the equation of symmetry
In the equation above, a=-1, b=2, c=3
Equation of symmetry, [tex]x=-\dfrac{b}{2a}[/tex]
[tex]x=-\dfrac{2}{2*-1}\\x=1[/tex]
Step 2: Find the value of y at the point of symmetry
That is, we substitute x obtained above into the y and solve.
[tex]y(1)= -1^2 + 2(1) + 3=-1+2+3=4m[/tex]
The maximum height of the diver is therefore 4 meters.

What force is necessary to accelerate a 1,350 kg car at a rate of 38 m/s??
35.53 N
5,130 N
1.388 N
51.300 N
Answer:
Force, F = 51300 N
Step-by-step explanation:
We have,
Mass of a car is 1350 kg
Acceleration of the car is 38 m/s².
It is required to find the force required to accelerate the car. The force acting on the object is given by the formula as follows:
[tex]F=ma\\\\F=1350\ kg\times 38\ m/s^2\\\\F=51300\ N[/tex]
So, the force of 51300 N is required to accelerate the car.

In ΔABC, the measure of ∠C=90°, the measure of ∠A=64°, and AB = 2.7 feet. Find the length of BC to the nearest tenth of a foot.
Answer:
Applying sine theorem for right triangle ABC, we have:
sin A = BC/AB
=> BC = AB x sin A = 2.7 x sin(64 deg) = ~2.4 (ft)

Problem 1. $625 for the bus hire per friday, So 625*4=$2500
Problem 2. 2500/25=$100 each for the whole 4 weeks
Problem 3.
10 students tickets 220= 2200 for all tickets. The bus, 625/10 = $62.5*4= $250 dollars for the whole 4 weeks for the bus so in all each student pays $470 each
20 students, tickets 220=4400 for all tickets. The bus, 625/20=$31.25*4=$125 for the whole 4 weeks for the bus, so in all each student must pay $345 each
30 students, tickets 220 = 6600 for all tickets. The bus, 625/30 =$20.83*4=$83.32 for the whole 4 weeks for the bus, so in all each student must pay $303.32 each
41 students, tickets $160=$6560 for all tickets. The bus, because you need 2 buses at 625 each so $1250 for both buses 1250/41= 30.49*4=$121.96 for the whole 4 weeks for the bus. So in al each student must pay $281.96 each

a card is drawn at random from a standard 52 card deck has a 1/13 chance of being at 8. What is the probability of the car not being an ace?
Answer:
12/13
Step-by-step explanation:
There are 52 cards in the deck

What is the value of x in the equation 8x – 2y = 48, when y = 4?
6
7
14
48
Answer:
x=7
Step-by-step explanation:
8x – 2y = 48
Let y = 4
8x - 2(4) = 48
8x - 8 = 48
Add 8 to each side
8x-8+8 = 48+8
8x = 56
Divide each side by 8
8x/8 = 56/8
x=7
Answer:
[tex]x = 7[/tex]
Step-by-step explanation:
[tex]8x - 2y = 48 \\ 8x = 48 + 2y \\ x = \frac{48 + 2y}{8} [/tex]
[tex]y = 4[/tex]
[tex]x = \frac{48 + 2y}{8} \\ x = \frac{48 + 2 \times 4}{8} \\ x = \frac{48 + 8}{8} \\ x = \frac{56}{8} \\ x = 7[/tex]

For this week only, you can buy a Dell for $2988, including taxes. Included in the offer is a finance option for 4 years at an annual percentage rate of 3.5%. Find the monthly payment.
Answer:
$66.80
Step-by-step explanation:
The monthly payment can be computed using the pmt formula in excel spreadsheet as shown below:
=pmt(rate,nper,-pv,fv)
the rate is the interest rate of 3.5% divided by 12 months to show interest rate per month
nper is the number of months it would take to complete the payments which is 4 years multiplied by 12 months i.e 48 months
pv is the cost of the gadget at $2,988
fv is the sum of all month payments which is not unknown
=pmt(3.5%/12,48,-2988,0)=$66.80

The probability of reference book and then, without replacing it, picks up a nonfiction book is 5/136.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Nadia's bookshelf contains 10 fiction books, two reference books, and five nonfiction books.
So, the probability of getting reference book
= 2/ 17
and, the probability of getting nonfiction book
= 5/ 17
Now, the probability of reference book and then, without replacing it, picks up a nonfiction book
= 2/ 17 x 5 / 16
= 10 / 272
= 5 /136

Answer:
108
Step-by-step explanation:
So the area of the rectangle is easy.
12 * 5 = 60
Now you have to do the triangles.
The height is (13 - 5) / 2 = 4
The bases are 12
The area of one is (12 * 4) / 2
The area of both is 12 * 4 = 48
60 + 48 = 108
