Answer:
625 cm^2
Step-by-step explanation:
Break it into a rectangle on the bottom and a triangle on top
rectangle area = 50 x 8 = 400 cm^2
triangle area = 1/2 b * h = 1/2 * 50 * 9 = 225 cm^2
added together = 625 cm^2
Define each following sets by listing its elements, the set of letters in the word "salt"
The word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}
What is set?A set is a collection of clearly - defined unique items. The term "well-defined" applies to a property that makes it simple to establish whether an entity actually belongs to a set. The term 'unique' denotes that all the objects in a set must be different.
We have given letter:
"salt"
Here, no letter is repeated.
So we can write it as roaster form:
Let's denote the set as S
S = {s, a, l, t}
Number of element in the set = 4
We can make new set from it if the set has only vowels
S(v) = {a}
If set has only consonants:
S(c) = {a, l, t}
Thus, the word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}

in the diagram below. C is an equal distance to A and B.
Answer:
C(50;-20)
Step-by-step explanation:
The question is asking for the midpoint of the line.
The triangle is formed by placing a line directly from the y-axis to the x-axis.
The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].
your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.
Your coordinates for B are (100;0)
C[(x1+x2)/2 ; (y1+y2)/2 ]
C [(0+100)/2 ; (-40+0)/2 ]
C[ 100/2 ; -40/2]
C (50 ; -20)
The diameter of a wheel is 150 cm, if the wheel travels 376.8 m, how many times does the wheel rotate?
Answer:
79.94
Step-by-step explanation:
First, let us find the circumference of the wheel (circle).
For that, let us use the below formula.
C = π × d
Given that,
d ⇒ diameter ⇒ 150 cm ⇒ 1.5 m
Let us find now.
C = π d
C = 3.142 × 1.5
C = 4.713
And now to find the number of times that the wheel rotates, you have to divide the total distance that wheel traveled by it's circumference.
Let us find now.
No. of times that wheel rotates = 376.8m ÷ 4.713m
No. of times that wheel rotates = 79.94
Approximately, the wheel will rotates 80 times.

if y-x=4 and x is three times the value of y, what is the value of x + y?
A) -8
b) -4
c) 0
d) 6
e) 8
Answer:
E = 8
Step-by-step explanation:
y - x = 4
y - (3y) = 4
y - 3y = 4
2y = 4
y = 4/2
y = 2
x = 3y
x = 3×2
x = 6
x + y = 2+6
x+y = 8

Step-by-step explanation:
The problem is put in different fractions to make it more confusing.

We can find the common denominator of all of the fractions.
[tex]1 \frac{1}{15} + 1 \frac{9}{15} + 1 \frac{10}{15} \\= 3+\frac{20}{15} =4 \frac{5}{15}\\\\=[/tex]4 1/3
[tex]monday = 1 \frac{1}{15} [/tex]
[tex]tuesday = 1 \frac{3}{5} [/tex]
[tex]wednesday = 1 \frac{2}{3} [/tex]
to find:the total number of miles Kenya ran in 3 days.
solution:[tex] \frac{16}{15} + \frac{8}{5} + \frac{5}{3} [/tex]
[tex] = \frac{16}{15} + \frac{8 \times 3}{5 \times 3} + \frac{5 \times 5}{3 \times 5} [/tex]
[tex] = \frac{16 + 24 + 25}{15} [/tex]
[tex] = \frac{65}{15} = \frac{13}{3} [/tex]
[tex] = 4 \frac{1}{3} [/tex]

A 9-foot piece of cotton cloth costs $15.84. What is the price per yard?
Hi!
How do we convert feet into yards?One yard is equal to 3 feet.
Therefore, we can simply divide the number of feet by 3 to get the number of yards.
First, let's convert 9 feet into yards.
9/3 = 3 yards
So, we know that 3 yards of cotton cloth cost $15.84
To get the price per yard, we want to divide the number by 3, as there are 3 yards total.
We will get the price per yard by doing that.
15.84 / 3 = 5.28
Therefore, the price per yard is $5.28.
For a similar problem, see:
https://brainly.com/question/22543439
Answer: $5.28 per yard
Step-by-step explanation:
There are 3 feet in one yard. We can divide 9 by 3 to see how many yards the price given is for.
9 / 3 = 3
This piece of cotton cloth is 3 yards. To find the price of one yard, we will divide the cost given by 3.
$15.84 / 3 = $5.28 per yard
The price per yard is $5.28.

Answer:
the last answer is correct, lim as it aproaches 33- is -6, and as it aproaches 33+ is -15
Step-by-step explanation:
The limit as the function approaches 33+ means the limit as the function approaches 33 from the right side, and the table shows it approaches 15 from x is above 33.
When x is slightly below 33, it aproaches -6.
The values of lim g (x) when x → - 33 and lim g(x) when x → 33 are,
⇒ - 6 and 15
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
We have to given that;
Table shown the relation between x and g (x).
Now, By table we get;
At x = 32.999;
g (x) = - 6.01
At x = 33.001;
g (x) = - 15.01
Thus, The values of lim g (x) when x → - 33 and lim g(x) when x → 33 are,
⇒ - 6 and 15
