Answer:
False
Step-by-step explanation:
To be able to build a triangle, the sum of the lengths of any 2 sides must be greater than the length of the third side.
With lengths 9, 7, and 16, 9 + 7 = 16.
You would need 9 + 7 > 16.
Therefore, these sides cannot be used for a triangle.
Find the value of n.
3+ (2 + 8) = (3 + 2) + n
Answer: n=8
Step-by-step explanation: 3+2+8=13
3+2=5 so 13-5=8
Answer:
n=8
Step-by-step explanation:
PEMDAS:
Solve out each side then subtract 5 from the side with n.
Work:
3+(2+8)=(3+2)+n
3+10=5+n
13=5+n
8=n

What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
To solve this problem, we first need to calculate the original surface area of the complex solid.
The complex solid is composed of two rectangular prisms, one with dimensions 9.8 ft × 6.5 ft × 8.1 ft and one with dimensions 10.6 ft × 4.3 ft × 6.5 ft.
The surface area of the first rectangular prism is:
2(9.8 × 6.5) + 2(9.8 × 8.1) + 2(6.5 × 8.1) = 464.82 ft²
The surface area of the second rectangular prism is:
2(10.6 × 4.3) + 2(10.6 × 6.5) + 2(4.3 × 6.5) = 411.22 ft²
So the total original surface area of the complex solid is:
464.82 + 411.22 = 876.04 ft²
Now we need to find the new surface area, which is exactly 14 times the original surface area.
Therefore, we can write:
New surface area = 14 × original surface area
New surface area = 14 × 876.04
New surface area ≈ 12264.56 ft²
Thus,
The new surface area is approximately 12264.56 ft².

3. Suppose a serial number must consist of four different digits, followed by two
different letters. How many different serial numbers are possible?
Answer: 6,760,000 different possible serial numbers.
Step-by-step explanation: There are 10 digits numbered 0 to 9. There are also 26 letters in the alphabet. Using this, we can do 10*10*10*10*26*26 as there are four digits needed and two letters. This computes to approximately 6,760,000 different possible serial numbers, assuming no other factors are involved.
Every cereal box has a gift inside, but you cannot tell from the outside what the gift is. The store manager assures you that 13 of the 62 boxes on the shelf have the secret decoder ring. The other 49 boxes on the shelf have a different gift inside. If you randomly select two boxes of cereal from the shelf to purchase, what is the probability that BOTH of them have the secret decoder ring?
Answer:
I'm pretty sure it is 7.4% or 0.074.
Step-by-step explanation:
Answer:
0.041 = 4.1%
Step-by-step explanation:
The probability the first box has a secret decoder ring is 13/62.
The probability the second box has a secret decoder ring is 12/61.
The probability of both is:
P = (13/62) (12/61)

Find the sum of the first 45 terms of the following series, to the nearest integer. 2,11, 20, ...
Answer:
[tex]S_{45}[/tex] = 9000
Step-by-step explanation:
there is a common difference between consecutive terms , that is
11 - 2 = 20 - 11 = 9
this indicates the sequence is arithmetic with nth term
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
here a₁ = 2 and d = 9 , then
[tex]S_{45}[/tex] = [tex]\frac{45}{2}[/tex] [ (2 × 2) + (44 × 9) ]
= 22.5(4 + 396)
= 22.5 × 400
= 9000

Joe has $6.40 in nickels and quarters. He has two more nickels than quarters. How many quarters does Joe have?
Answer:
Quaters - Q=12
Dimes - D=10
Nickels - N= 48
Step-by-step explanation:
First, notice that $6.40 = 640 cents. The corresponding linear equation and a solution is shown below in several steps:
Original equation for amount of Dimes (D):
10*D + 25*(D+2) +5*4*(D+2) = 640
Simplified as following, resulting in the answer for D:
55*D=550
D=10
thus having the amount of Quarters:
Q=12
and correspondingly, amount of Nickels:
N= 48
Answer:
Quarters = 12
And correspondingly, amount of Nickels:
Nickels = 48

A triangle has an angle that measures 10°. The other two angles are in a ratio of 3:14. What
are the measures of those two angles?
Step-by-step explanation:
Need to FinD :We have to find the measures of other two angles of triangle.[tex] \red{\frak{Given}} \begin{cases} & \sf{The\ measure\ of\ one\ angle\ of\ traingle\ is\ {\pmb{\sf{10^{\circ}}}}.} \\ & \sf{The\ other\ two\ angles\ are\ in\ the\ ratio\ of\ {\pmb{\sf{3\ :\ 14}}}.} \end{cases}[/tex]
We know that,
The other two angles of triangle are in the ratio of 3 : 14. So, let us consider the other two angles of the triangle be 3x and 14x.Angle sum property,
The angle sum property of triangle states that the sum of interior angles of triangle is 180°. By using this property, we'll find the other two angles of the triangle.[tex]\rule{200}{3}[/tex]
[tex] \sf \dashrightarrow {10^{\circ}\ +\ 3x\ +\ 14x\ =\ 180^{\circ}} \\ \\ \\ \sf \dashrightarrow {10^{\circ}\ +\ 17x\ =\ 180^{\circ}} \\ \\ \\ \sf \dashrightarrow {17x\ =\ 180^{\circ}\ -\ 10^{\circ}} \\ \\ \\ \sf \dashrightarrow {17x\ =\ 170^{\circ}} \\ \\ \\ \sf \dashrightarrow {x\ =\ \dfrac{\cancel{170^{\circ}}}{\cancel{17}}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{x\ =\ 10^{\circ}.}}}}_{\sf \blue {\tiny{Value\ of\ x}}}} [/tex]
∴ Hence, the value of x is 10°. Now, let us find out the other two angles of the triangle.
[tex]\rule{200}{3}[/tex]
Second AnglE :
3x3 × 1030°∴ Hence, the measure of the second angle of triangle is 30°. Now, let us find out the third angle of triangle.
[tex]\rule{200}{3}[/tex]
Third AnglE :
14x 14 × 10140°∴ Hence, the measure of the third angle of the triangle is 140°.
Given an equilateral triangle with side lengths 18 cm. What is the height of the triangle?
O 18 cm
O 9 cm
o 93 cm
O 183 cm
Step-by-step explanation:
If you draw an altitude of the right triangle, you get that the legs are (18/2)=9 and the height (which I'll call x) and a hypotenuse of 18.
By the Pythagorean theorem,
[tex] {9}^{2} + {x}^{2} = {18}^{2} \\ 81 + {x}^{2} = 324 \\ {x}^{2} = 243 \\ x = \sqrt{243} = 9 \sqrt{3} [/tex]

Let f(x) = 3 * sqrt(x) + 7. Define g$to be the inverse of f.
What is the value of g(g(f(f(f(36)))))?
By using the definition of inverse functions, we will see that:
g(g(f(f(f(36))))) = f(36) = 25.
What are inverse functions?Two functions f(x) and g(x) are inverses if:
f( g(x) ) = x
g( f(x) ) = x
Then we can rewrite:
g(g(f(f(f(36)))))
First, we can see that:
g(f(f(f(36)))) = f(f(36))
Replacing that in our expression, we get:
g(g(f(f(f36))))) = g(f(f(36)))
And the above expression is equal to f(36), to be sure of that, let's replace:
u = f(36)
Then we can rewrite:
g(f(f(36))) = g(f(u))
And by definition, the above thing is equal to u:
g(f(u)) = u = f(36).
Finally, we conclude that:
g(g(f(f(f(36))))) = f(36) = 3*√36 + 7 = 3*6 + 7 = 25
