A statue is in the shape of a triangular pyramid. The area of the base of the statue is 18 square inches and it has a height of 15 inches. What is the volume of the statue in cubic inches? 60 in.3 90 in.3 270 in.3 540 in.3? Thanks!~
Answer:
90 cubic inches
Step-by-step explanation:
V = 1/3 · area of base · height
V = 1/3 · 18 · 15
V = 6 · 15
V = 90
Answer:
if your online school is tops its a hundred percent 90 inch^3

Samuel is going to invest $4,900 and leave it in an account for 14 years. Assuming the
interest is compounded monthly, what interest rate, to the nearest tenth of a percent,
would be required in order for Samuel to end up with $10,300?
-
Answer:
Submit Answer
Answer:
0.053
Step-by-step explanation:
Using the compound formula A=P(1+r/n)^nt we can plug in the numbers we know. A being the total, P the initial amount, n is the number of compounds in a year, and t is the number of years passing. So 10300= 4900(1+ r/12)^12(14). We have to isolate r in order to find the rate. We can divide both sides by 4900, giving us 103/49= (1+ r/12)^168. Then we take the 168 square root from both sides. 1.00443… = 1 + r/12. Subtract 1 from both sides. 0.00443… = r/12. Then multiply both sides by twelve . r= 0.053

Answer:
6. p = 4
7. m = 7
8. n = 13
9. z = 5
10. x = 4
11. y = 9
Step-by-step explanation:
You can divide the solution by the number next to the letters/variables.
For example, to find 9p = 36 you can do 36 ÷ 9 which equals 4.
To double check, you can multiply your quotient by the divisor.
So to check if p = 4, you can do 9 x 4 which equals 36, therefore it is the solution.
given: x+y=10 if x=-21, what is y?
Answer: y = 31
Step-by-step explanation: all you need to do is plug in the x
since x = -21 we can put: -21 + y = 10
now we add 21 to both sides giving us: y = 31
Answer:
(-21,22)
Step-by-step explanation:
x+y=10
x=-21
subtitue the x value
-21+y=2
solve for y
y=22
Then write your answer by ordered pair
(-21,22)

Please mark my answer as the brainliest
Answer:
Answer vary:
3:3
Step-by-step explanation:
honestly in my opinion that’s the answer.
all you need is to understand what a ratio is, so all your doing is figuring out how many males to females are their.
meaning of ratio : the quantities relation between two amounts showing the number of times on value contains or is contained within the other.

f(x) = 4x² + 7x – 18
Find f(-9)
Step-by-step explanation:
f(x) = 4x² + 7x - 18
f(-9) = 4 * (-9)² + 7 * (-9) - 18
= 324 - 63 - 18
= 243

Please can i have the answer?
Answer:
a- 48: 2×2×2×2×3
56: 2×2×2×7
GCF: 2×2×2=8
b- 48+56=8(6+7)
Answer:
8(6+7)
Step-by-step explanation:
First, find the GCF of 48 and 56. The GCF of 48 and 56 is:
8So the GCF, 8, will go outside the parenthesis. Then inside the parenthesis will be 48+56. Although first, you need to divide each of these by 8. So the numbers inside the parenthesis will actually be 6+7.
So the final answer is:

A stegosaurus eats ten twelfths of a plant and then eats two twelfths of the plant later. Estimate how much of the plant the dinosaur ate in all. Explain your thinking.
Answer:
1/2 ; 0 ; 2 ;
Step-by-step explanation:
3 / 8 to the nearest half
3/8 = 0.375
Using a number line, 0.375 is closer to 1/2 =0.5, than to 0 ; hence, 3/8 = 1/2(nearest half
2.) 2 /12 = 0.16666
2/12 = 0 (nearest 1/2)
3.) eight tenths plus nine tenths equals
8/ 10 + 9/10 = 17/10
17 /10 = 1.7
1.7 = 2 (nearest 1/2)
Use the graph of the polynomial
function to find the factored form of
its related polynomial. Assume it
has no constant factor
Answer:
The factored form of the polynomial is [tex]y = (x-2)\cdot (x+1)[/tex].
Step-by-step explanation:
According to the graph, we have a second order polynomial with a vertical axis of symmetry. The standard form of the polynomial is:
[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficients.
We can obtain the solution of the polynomial by knowing three distinct points. From graph we know that the curve pass through the following three points: [tex](x_{1},y_{1}) = (-1, 0)[/tex], [tex](x_{2},y_{2}) = (0, -2)[/tex], [tex](x_{3},y_{3}) = (2,0)[/tex]. Three linear equations are constructed:
[tex]a^{2}-b+c = 0[/tex] (2)
[tex]c = -2[/tex] (3)
[tex]4\cdot a + 2\cdot b + c = 0[/tex] (4)
The solution of this system is [tex]a = 1[/tex], [tex]b = -1[/tex] and [tex]c = -2[/tex]. Then, the polynomial in standard form is [tex]y = x^{2}-x-2[/tex]. By factorization, we find that factored form is:
[tex]y = (x-2)\cdot (x+1)[/tex] (5)
