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

-1
0
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

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.

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.

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
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
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].
What is the perimeter, in -inches, of the square shown below? A 8 B 16. C 32 D 64
Answer:
The perimeter, in inches, is 32.
Step-by-step explanation:
Since this shape is a square, we know that all sides are equal.
The information given to us is that one side of the square measures 8 inches.
8 + 8 + 8 + 8 = 32
Answer:
c 32
Step-by-step explanation:
Squares have 4 sides of the same length
8 * 4 = 32
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

What is the area of a rectangle with a length of (x - 5) and width of (x + 8)?
Answer:
a = x² + 3x - 40
Step-by-step explanation:
a = l * w
a = (x - 5)(x + 8)
a = x(x + 8) - 5(x + 8)
a = (x² + 8x) + (- 5x - 40)
a = x² + 3x - 40

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 roundedA local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful only if the average time spent on a delivery does not exceed 40 minutes. The owner has randomly selected 21 customers and delivered pizzas to their homes. What hypotheses should the owner test to demonstrate that the pizza delivery will not be successful
Answer:
H0 : u ≤ 40 mins against Ha: u> 40 mins
Step-by-step explanation:
The hypotheses will be set as follows
H0 : u ≤ 40 mins against Ha: u> 40 mins
The null hypothesis is that the mean delivery time is less and equal to 40 minutes.
against the claim
that the mean delivery time is greater than 40 minutes.
40 minutes is taken because the success depends on the factor that if the delivery time is less and equal to 40 minutes then the home delivery service will be successful
But if it is greater than 40 minutes then the home delivery service will not be successful
The table of values represent a linear function. Write an equation in slope-intercept form that represents the function.
Let's take the first value of x and y.
When x = 4, y = -3. This also gives us point
(4, -3). We need another point to find the slope.
From the table I see the point (5, -4.5)
.
See it?
Let m = slope
m = (-4.5 -(-3))/(5-4)
m = (-4.5 + 3)/1
m = (-1.5)/1
m = -1.5
Now, use the slope m and one of the points to plug into the point-slope formula.
Here is the point-slope formula:
y - y_1 = m(x - x_1)
I will use the point (4, -3) and m.
y - (-3) = -1.5(x - 4)
y + 3 = -1.5x + 6
The slope-intercept form we want is
y = mx + b.
y = -1.5x + 3
