Answer:
3003Step-by-step explanation:
Teams of 5 from the total of 15 students.
Combination of 5 is:
nCr = n!/(n-r)!*r!15C5 = 15!/10!5! = 15*14*13*12*11/(2*3*4*5) = 3003 teamstia mixes mashed pumpkin

Mrs. Hector wanted to bring giant souvenir snow globes, which weigh 1.5 kg each, back to the USA as presents for her students. Mrs. Hector's suitcase weighs 2.4 kg, but she wanted to fill it with as many snow globes as possible. Write and solve an inequality to determine the maximum number of snow globes that Mrs. Hector could have brought back in her suitcase.
Answer:
the maximum number of snow balls can bought back = 1.6
Step-by-step explanation:
Let
Mrs. Hector brings total number of giant snow globes = x
As given,
weight of 1 snow globe = 1.5 kg
So,
Weight of x snow globe = 1.5x
As given,
She have to take them in a suitcase of weight 2.4 kg
∴
For number of snow globes we have the equation,
1.5x = 2.4
⇒x = [tex]\frac{2.4}{1.5}[/tex] = 1.6
So, the maximum number of snow balls can bought back = 1.6
A tree grows 2 inches per year. It was 14 inches tall when it was planted. what would be this function discrete continuous or neither? whould it be a linear an exponential or neither? what would be the domain?
please help greatly appreciated
Answer:
This function is a continuous linear function that's domain is all positive real numbers.
Step-by-step explanation:
This function is continuous because every linear function is continuous and this function is the linear function y = 2x+14 where x is the years it has been planted and y is the height.
It is a linear function, it's hard to explain, but it has a dependent variable, the height of the tree that changes at a constant rate with the independent variable which is time in years.
The domain is all positive real numbers since time/years can not be negative.
find the value of the variables. x and y
Answer:
x = 29.4
y = 17
Step-by-step explanation:
sin 90° / 34 = sin 60° / x
x = 34·sin 60°
x = 29.4
sin 90° / 34 = sin 30° / y
y = 34·sin 30°
y = 17
solve for the altitude to the base of an isosceles traingle given a leg is 16yd and the perimeter is 56yd
Answer:
one yard is equal to 3 feet so
An object moves around x + y = 25 (which represents a
circle whose radius is 5 meters) at a constant speed. At time
t = 0 seconds, the object is at (5,0). When t = 1, it is at (4,3). Where is the object when t = 2? When t = 3? when t = n?
What is the object’s speed? At what times does the object return to (5, 0)? To arrive at your answers, what assumptions did you make?
Answer:
Step-by-step explanation:
There is an error in the question.
x + y = 25 is NOT the equation of a circle.
It should be x^2 + y^2 = 5^2.
Parametric equations for the circle:
x = 5cosθ
y = 5sinθ
After 1 second, the object is at (4,3), so θ=arctan(3/4).
At 2 seconds, θ=2arctan(3/4). The object is at (5cosθ,5sinθ) = (1.4, 4.8).
At 3 seconds, θ=3arctan(3/4). The object is at (-1.76, 4.68).
360°/arctan(3/4) ≈ 9.764
The object returns to (5,0) after 9.764 seconds.
What is the answer hurry!!!
Answer:
D. 9 + 4√5
Step-by-step explanation:
What we're essentially doing here is squaring 2 + √5. (2 + √5 and 2 + 1√5 are essentially the same)
(2 + √5)(2 + √5) (I didn't put the one on the conjugate for a reason; look above)
Step 1: Apply the distributive property by multiplying each term of 2 + √5 by 2 + √5
4 + 2√5 + 2√5 + (√5)²
Step 2: Combine 2√5 and 2√5 to get 4√5.
4 + 4√5 + (√5)²
Step 3: The square of √5 is 5.
4 + 4√5 + 5
Step 4: Add 4 and 5 to get 9.
9 + 4√5 is the final answer to this question.

1. What should be added to the difference of 35.06 and 2.098 to get 40.00?
Answer:
7.038
Step-by-step explanation:
35.06-2.098=32.962
40.00-32.962=7.038
Answer:
7.038
u can find the difference of 35.06 and 2.098 first.
afterwards, u can subtract the difference from 40.00 to get the answer of 7.038

Which equation represents the line that has a slope of -2 and passes through the point (6,5)?
A. y= -2.6 - 17
B. Y = -23 - 16
c. y = -2x + 16
D. y = -2.c + 17
Pls don’t write random thing I really need helllppp
Answer:
y = - 2x + 17
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, then
y = - 2x + c ← is the partial equation
To find c substitute (6, 5) into the partial equation
5 = - 12 + c ⇒ c = 5 + 12 = 17
y = - 2x + 17 ← equation of line

A large field measures 70 feet by 525 feet. If you divide it up into equal square garden plots, what size would the largest possible plot be with sides of whole number length?
9514 1404 393
Answer:
35 feet square
Step-by-step explanation:
The greatest common factor of 70 and 525 is 35. The largest square plot can be 35 feet on a side.
70 = 2·35
525 = 15·35

I like to find the GCD (greatest common divisor) using Euclid's algorithm. We find the remainder when dividing the larger by the smaller. When that remainder is not zero, we replace the larger number with the remainder, and repeat. When the remainder is zero, the divisor is the GCD.
525/70 = 7 r 35
70/35 = 2 r 0 . . . . . 35 is the GCD

what is the rule for solving any equation?
A. just look at it and it will be solved
B. always add the numbers
C. Do the inverse or opposite operations
D. the is no rule for solving equations
Answer:
C) Do the inverse or opposite operations
Step-by-step explanation:
Take for example the equation 4=2x. Because 2 is being multiplied by x, the only way for x to get by itself is to do the opposite operation; dividing both sides by 2 to get 2=x.

Answer:
z is 95 degrees.
Step-by-step explanation:
Linear angle pairs make 180 degrees. Since ∠ABC is a straight line, it is 180 degrees. And since ∠ABD and ∠DBC are on that line, they are a linear angle pair. You just need to find out what number + 85 degrees would = 180 degrees, which in this case, is 95.
