Answer:
250 in²
Step-by-step explanation:
There are four identical rectangles so therefore area of one rectangle times 4. Then add the sum of the areas of the two identical squares.
4( l x b) + 2( l x b)
4( 10 x 5) + 2(5 x 5)
4(50) + 2(25)
200 + 50
Therefore 250 in²
Cars enter a car wash at a mean rate of 3 cars per half an hour. What is the probability that, in any hour, at least 3 cars will enter the car wash
Answer:
0.938
Step-by-step explanation:
Using the poisson probability relation:
P(x = x) = (e^-λ * λ^x) ÷ x!
λ = 3 per half an hour = 6 cars per hour
P(x ≥ 3) = 1 - [p(x = 0) + p(x = 1). + p(x = 2)]
P(x ≥ 3) = (e^-6* (6^0 + 6^1 + 6^2/2!))
P(x ≥ 3) = 1 - (e^-6 * (1 + 6 + 18)
P(x ≥ 3) = 1 - (e^-6 * 25)
P(x ≥ 3) = 1 - (0.0024787 * 25)
P(x ≥ 3) = 1 - 0.0619688
P(x ≥ 3) = 0.9380311
= 0.938

Find the range for the measures for the third side of a triangle with the given measures of two sides. 14 and 23
Given:
Two sides of a triangle are 14 and 23.
To find:
The angle for the measures for the third side of a triangle.
Solution:
If a, b, c are three sides of a triangle, then
[tex]a+b>c[/tex]
[tex]a+c>b[/tex]
[tex]b+c>a[/tex]
It is given that two sides of a triangle are 14 and 23.
Let the third side of the given triangle be c. Then, using the above inequalities, we get
[tex]a+b>c[/tex]
[tex]14+23>c[/tex]
[tex]37>c[/tex] ...(i)
Similarly,
[tex]a+c>b[/tex]
[tex]14+c>23[/tex]
[tex]c>23-14[/tex]
[tex]c>9[/tex] ...(ii)
And,
[tex]b+c>a[/tex]
[tex]23+c>14[/tex]
[tex]c>14-23[/tex]
[tex]c>-9[/tex] ...(iii)
Using (i), (ii) and (iii), we get
[tex]9<c<37[/tex]
Therefore, the range for third side of the triangle is [tex]9<c<37[/tex].

10 cm
12 cm
5 cm
3 cm
Choose 1 answer:
A
(5 cm x 12 cm x 5 cm) + (3 cm x 10 cm x 12 cm)
B
(5 cm x 5 cm x 3 cm) + (3 cm x 10 cm)
(12 cm x 5 cm x 5 cm) + (5 cm x 3 cm x 10 cm)
(5 cm x 12 cm x 5 cm) + (3 cm x 10 cm)
Answer:
Area of rectangle is L*W*H
therefore, (5 cm x 12 cm x 5 cm) + (3 cm x 10 cm x 12 cm) is the answer.

HELP PLEASE!!!! Find x.
Answer:
x = 33
Step-by-step explanation:
these two angles are a linear pair, they form a straight line
there are 180 degrees in a straight line
so you can add each expression and have sum equal 180
2x-18 + 4x = 180
6x - 18 = 180
6x = 198
x = 33

Two numbers are consecutive positive multiples of 3. Three
times the larger of the numbers is 7
10
of 5 times the smaller.
What are the numbers?
9514 1404 393
Answer:
18, 21
Step-by-step explanation:
Let x represent the smaller number. Then x+3 is the larger number, and the other relation between them is ...
3(x+3) = (7/10)(5x)
6x +18 = 7x . . . . . multiply by 2 and simplify
18 = x . . . . . . . . . . subtract 6x
The two numbers are 18 and 21.

Find all x and y intercepts of the graph of the function f(x)= 2x^3+6x^2-2x-6
9514 1404 393
Answer:
y-intercept: (0, -6)x-intercepts: (-3, 0), (-1, 0), (1, 0)Step-by-step explanation:
We notice the first pair of coefficients is the same as the last pair (with the sign changed). This means we can factor by grouping.
f(x) = (2x^3 +6x^2) -(2x +6)
f(x) = 2x^2(x +3) -2(x +3)
f(x) = 2(x^2 -1)(x +3) = 2(x -1)(x +1)(x +3)
The factors are made to be zero when x is 1, -1, or -3.
The x-intercepts are (1, 0), (-1, 0), (-3, 0).
The y-intercept is the constant, -6.
Frequency of y=sin0/3
Answer:
y=sin(°/3) means that y equals the sine of a given degree divided by 3.

Find the surface area of the following figures.
with solution please. T-T
Answer:
1.a=5cm
Surface area :6a²=6×5²=150cm²
2.r=3cm
h=5cm
total surface area of cylinder =2πr(r+h)
=2π×3(3+5)=48π cm²
3.
l=4m
b=5m
h=2m
now.surface area =2(lb+lh+bh)
=2(4*5+4*2+5*2)
=76m²
4.
r=6cm
surface area =4πr²=4*π*6²=144πcm²
5.
slant height (S)=8cm
length =breadth=(L)=4cm
Surface area of pyramid =area of base + 2* area of trainglular face
=L²+2*S*L
=4²+2*8*4
=80cm²

Answer:
0
Step-by-step explanation:
given the system of equations, what is the value of the system to determinant.
x + y = 8
x + y = 10
This can be written in the form AX = b
A is a 2 by 2 matrices
b is a column matrix
Taking the determinant of A
[tex]A =\left[\begin{array}{ccc}1&1\\1&1\\\end{array}\right][/tex]
We are to finds the determinant
|A| = 1(1) - 1(1)
|A| = 1 -1
|A| = 0
hence the required determinant is 0

Radha purchased a cosmetic item at 5 % discount. If she got the discount amount of
Rs 74, at what price did she purchase the item?
200 uhon VAT of 13% is levied
Answer:
She purchased the item at a price of Rs 1,406.
Step-by-step explanation:
5% of discount:
This means that she paid 100% - 5% = 95% = 0.95 of the original price of x, that is, 0.95x, and 0.05x was the discount.
Original price:
She got the discount amount of Rs 74.
74 is 5% of the original price, that is:
[tex]0.05x = 74[/tex]
[tex]x = \frac{74}{0.05}[/tex]
[tex]x = 1480[/tex]
What price she purchased:
74 subtracted from the original price, that is, x - 74. So 1480 - 74 = 1406.
She purchased the item at a price of Rs 1,406.

ABC Bookstore sells packages of books that include both new and used books. New books cost $16 and used books cost $8. The bookstore wants to sell packages that have 30 books total, and the store charges $336 for each package. How many new and used books will be in each package?
A. 318 new, 12 used
B. 12 new, 18 used
C. 16 new, 8 used
D. 8 new, 16 used
(It's B, just took the test)
Answer:
b
Step-by-step explanation:
the following equations can be determined from the question
16n + 8o = 336 equation 1
n + o = 30 equation 2
where n = new books
o = old books
Multiply equation 2 by 8
8n + 8o = 240 equation 3
subtract equation 2 from 1
8n = 96
n = 12
substitute for n in equation 2
12 + o = 30
o = 18
Answer:
B. 12 new, 18 used

A 20 foot ladder is leaning against a 25 foot building. The bottom of the ladder is 9 feet away from the building. How high is the top of the ladder above the ground?
Answer:
17.9 feetStep-by-step explanation:
This is a right triangle
the 20 foot ladder is the hypotenuse
The 9 foot at the bottom is one leg
The height is the remaining leg
Use the pythagorean theorem
a² + b² = c²
a² + 9² = 20²
Subtract 9² from both sides
a² = 20² - 9²
a² = 400 - 81
a² = 319
Take the square root of both sides
a = 17.860571099491752
rounded
17.9 feet
Answer:
A ladder is the hypotenuse of the right triangle.
Missing leg is x.
Use Pythagorean:
x² = 20² - 9²x² = 319x = √319x = 17.86 feet or 18 feet roundedgiven A = (3, -2 ) and B = (1, - 1) find A + B PLS HELP LOL
