Answer:
a(10) = 170
Step-by-step explanation:
Given that,
The nth term fo the sequence is :
a(n) = n² + 7n
We need to find the 10th term of the sequence.
Put n = 10 in the above sequence,
a(10) = (10)² + 7(10)
= 100 + 70
= 170
So, the 10th term of the sequence is 170.

Answer:
X= -2, -1, 0, 1
Step-by-step explanation:
X can be all of those
-2 ≤ X - this means that X is greater than -2 or equal
X< 2 - This means X is less than 2
so you find all the # from -2 to 1 because that is the number less than 2 so
-2, -1, 0, 1

A child toy is made by removing a triangular prism from the center of a wooden rectangular prism The triangular base of the triangular prism has a base length of 1 inch and a height of 1 inch. Write and solve an equation to find the volume of the toy.
*see attachment for the diagram given
Answer:
Volume of the toy = 68 in.³
Step-by-step explanation:
The equation to find the volume of the toy = volume of the wooden rectangular prism - volume of the triangular prism removed form the center
Volume of the toy = (L*W*H) - (½*bhl)
Where,
L = 8 inches
W = 3 inches
H = 3 inches
b = 1 inch
h = 1 inch
l = 8 inches
Plug in the values into the equation
Volume of the toy = (8*3*3) - (½*1*1*8)
Volume = 72 - 4
Volume of the toy = 68 in.³

Find b given that A (-6, 2), B (b, 0), and C (3,-4) are collinear.
Answer:
b = -3.
Step-by-step explanation:
If the 3 points are collinear then:
Slope of AB = Slope of BC and so
(0-2)/(b + 6) = (-4-0)/( 3 - b)
-4(b + 6) = -2(3 - b)
-4b - 24 = -6 + 2b
-24 + 6 = 2b + 4b
6b = -18
b = -3.

A car drove 5 miles in 30 minutes. How far will the car go in 1 hour?
Answer: 10 miles
Step-by-step explanation:
Practically, just look at it. 30 minutes = 5 miles, 60 minutes = 10 miles
Mathmatically, find the constant of proportionality.
30 minutes divided by 5 miles = 6 minutes per 1 mile. 60 minutes = 10 miles
Of all the animals admitted to the local pet hospital, 10 of them are dogs. They represent 25% of all the animals at the hospital. How many animals are at the hospital in total? A. 20 B. 30 C. 40 D. 50
Answer:
C. 40
Step-by-step explanation:
[tex]\frac{25}{100} = \frac{10}{y}[/tex]
[tex]\frac{1}{4} = \frac{10}{y}[/tex] (cross multiply)
40 = 1y (rewrite)

Step-by-step explanation:
Solve the equation using either addition or substitution. Show all your work
Answer:
(x1, y1) = (1, 3)
(x2, y2) = (4, 12)
Step-by-step explanation:
y= x^2 - 4
y= 5x - 8
(substitute the value for y)
x^2 - 4 = 5x - 8
(solve the equation)
x = 1
x = 4
(substitute the values)
y = 5 × 1 - 8
y = 5 × 4 - 8
(solve the equations)
y = -3
y = 12
( the possible solutions are)
x1, y1 = 1, -3
x2, y2 = 4, 12
(check the solutions)
-3 = 1^2 - 4
-3 = 5 × 1 - 8
12 = 4^2 - 4
12 = 5 × 4 - 8
(simplify)
-3 = -3
-3 = -3
12 = 12
12 = 12
(the ordered pairs are the solutions)
Which pairs of polygons are congruent? A. pairs 1, 2, 3, and 4 B. pairs 1 and 4 C. pairs 1, 2, and 3 D. pairs 2 and 4

x/3 less than or equal to 7
Answer:
x ≤ 21
Step-by-step explanation:
x/3 ≤ 7
x ≤ 21
Answer:
x ≤ 21
Step-by-step explanation:
With this problem, we have to solve for x, and to do that, we isolate the variable.
To do this, let’s get rid of the /3 from the x by multiplying both sides by 3
now we get x ≤ 7 times 3
finall, we get x≤21

Answer:
180
Step-by-step explanation:
From basic rules of a triangle we know that the interior angles of a triangle have to add up to equal 180°
But here is a formula for future references for finding the sum of the interior angles
interior angle sum = (n-2)180
where n = number of sides
and here is an example:
a triangle has 3 sides so we plug in 3 for n
(3-2)180
3-2=1
1*180 = 180
so the interior angles add up to equal 180

Lucy was born on 08/05/1999. How many eight digit codes could she make using the digits in her birthday
Answer:
3,360 different codes.
Step-by-step explanation:
Here we have a set of 8 numbers:
{0, 0, 1, 5, 8, 9, 9, 9}
Now we want to make an 8th digit code with those numbers (each number can be used only once)
Now let's count the number of options for each digit in the code.
For the first digit, we will have 8 options
For the second digit, we will have 7 options (because one was already taken)
For the third digit, we will have 6 options (because two were already taken)
you already can see the pattern here:
For the fourth digit, we will have 5 options
For the fifth digit, we will have 4 options
For the sixth digit, we will have 3 options
For the seventh digit, we will have 2 options
For the eighth digit, we will have 1 option.
The total number of codes will be equal to the product between the numbers of options for each digit, then we have that the total number of codes is:
N = 8*7*6*5*4*3*2*1 = 8!
But wait, you can see that the 9 is repeated 3 times (then we have 3*2*1 = 3! permutations for the nines), and the 0 is repeated two times (then we have 2*1 = 2! permutations for the zeros).
Then we need to divide the number of different codes that we found above by 3! and 2!.
We get that the total number of different codes is:
C = [tex]\frac{8!}{2!*3!} = \frac{8*7*6*5*4}{2} = 8*7*6*5*2 = 3,360[/tex]
3,360 different codes.
The number of eight digit code she can make is, 3360.
If any number have n digits, then number of ways it can be arranged = [tex]n![/tex]
Given that, Born date is, 08/05/1999
Total number of digits in birth date = 8
So, number of ways it can be arranged = [tex]8![/tex]
Since, In birth date 9 is three times and 0 is two times.
Therefore, number of arrangements = [tex]\frac{8!}{3!*2!}=3360[/tex]
Therefore, she can make 3360 eight digit codes from given birth date.
