He needs 20 more unit cubes to completely fill the prism
How to determine the number of unit cubes?The dimension of the prism is given as;
4 by 3 by 3
The volume is calculated as:
Volume = 4 * 3 * 3
Volume = 36
He has already filled 16 units.
So, the units remaining is
Remaining = 36 - 16
Evaluate
Remaining = 20
Hence, he needs 20 more unit cubes to completely fill the prism

It takes a bird 6 minutes to fly with a 10 mph tailwind from its nest to a bird
feeder. It takes 30 minutes for the bird to get back to its nest. What is the bird's
speed in still conditions? How far away is the bird feeder?
Answer:
The bird's speed is 50mph.
The bird's feeder is 25 miles away.
Step-by-step explanation:
10/6=x/30
6*x=30 is 6/30=x
x=5
6*5=30 so 10*5=50
x=50
mph/time=distance per hour
50/(1/2)=25 miles

the values in the table represent a linear function.
Answer:
B
Step-by-step explanation:
just find the equal difference of y values.
Step-by-step explanation:
to add to the explanation :
an arithmetic sequence is defined as
an = an-1 + d
so, every term of the sequence is created by adding the same constant d (the common difference) to the previous term.
therefore, you find the common difference by finding the difference of 2 sequential terms.
like here e.g.
a3 = 38
a4 = 53
53 - 38 = 15
bingo !
and to verify that it truly is an arithmetic sequence, we can quickly also check the differences between the other pairs. yes, they are all 15.
be prepared for a trap like
1 8
2 23
3 38
5 68
notice the sudden jump in x ? suddenly x is increased by 2.
that just means we compare
an and an-2 instead of an-1.
so, how is related to an-2 ?
an = an-1 + d = (an-2 + d) + d = an-2 + 2d
and so we would get
a3 = 38
a5 = 68
a5 - a3 = 2d = 30
d = 15
so, don't get confused by such jumps or gaps.
the table shows the results of rolling a die several times. To the nearest percent, what is the experimental probability of rolling a 6?
The experimental probability of rolling a 6 will be 13.3%
How to calculate the probability?The probability will be calculated thus:
= Number of times that 6 occured / Total number if outcomes
= 4/(7 + 4 + 4 - 5 + 6 + 4)
= 4/30
= 0.133
= 13.3%
Therefore, the probability is 0.133 or 13.3%.

Find the surface area of the square pyramid. Enter your answer in the box.
A square pyramid. The side length of the base is 11 centimeters. The height of each of the 4 triangular faces is 10 centimeters.
cm2
Answer:
341 cm²
Step-by-step explanation:
Formula :
Surface area = Area of 4 triangle faces + Area of square base
===============================================================
Solving :
⇒ Surface area = 4 × 1/2 × 11 × 10 + 11²
⇒ Surface area = 2 × 110 + 121
⇒ Surface area = 220 + 121
⇒ Surface area = 341 cm²
The surface area of the square pyramid is 341 square centimeter.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The surface area of a square pyramid is calculated by the equation S = B + 1/2 × P × S
where B is the area of the base,
P is the perimeter of the base, and
S is the slant height of the pyramid.
the area of the base =11×11
B=121 square centimeter
The perimeter of the base = 2(11+11)
P= 44 cm
Slant height (S) is 10 cm.
Surface Area = 121 + 1/2 (44×10)
=121+220
=341 square centimeter
Hence, the surface area of the square pyramid is 341 square centimeter.

What is the y-intercept of f(x) = 3x 2? a. (9,0) b. (0,9) c. (0,-9) d. (9,-9)
Answer:
f(x) = 3x + 9: y - intercept is option c. (0,-9)
f(x) = 3x - 9: y - intercept is option b. (0, 9)
Step-by-step explanation:
option a and d cant be correct since y = 0 in those answer when the y - intercept is when x = 0
If the function f(x) = 3x + 9
than x = 0
f(x) = 3(0) + 9
f(x) = 0 + 9
f(x) = 9
x = 0 and y = 9 (0, 9)
If the function f(x) = 3x - 9
than x = 0
f(x) = 3(0) - 9
f(x) = 0 - 9
f(x) = -9
x = 0 and y = -9 (0, -9)

Element X is a radioactive isotope such that every 26 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 680 grams, how much of the element would remain after 19 years, to the nearest whole number?
Answer:
410 g
Step-by-step explanation:
Radioactive decay can be modeled by an exponential equation. The amount remaining (y) after a time period (t) can be expressed in terms of the initial amount (a) and the half-life (h).
y = a(1/2)^(t/h)
__
We can use this equation with the given values to find the amount remaining.
y = (680 g)(1/2)^((19 yrs)/(26 yrs)) ≈ (680 g)(0.602583)
y ≈ 410 g
About 410 grams of element X will remain after 19 years.
