Answer:
b<16
Step-by-step explanation:
b/4<4. Multiply 4 on both sides. b has to be less than 16.
1 gram of sugar costs 5400
how much would 1 ton cost?
Answer:
5400000000
Step-by-step explanation:
1gram=5400
1kg=5400*1000 (1kg=1000gm)
=5400000
1quntal=5400000*100 (1quntal=100kg)
=540000000
1ton=540000000*10 (1ton=10 quntal)
=5400000000

Find the zeros of the function f (x) = 4x^2-16
Answer:
x=-2
x=2
Step-by-step explanation:
We can think of this equation like a statement
"4 times what squared minus sixteen is equal to zero"
First, we need to rearrange the equation:
[tex]4x^2=16[/tex]
Now using our common knowledge, we know that 4 times 4 is equal to 16
now we have another statement:
"x times x is going to be equal to 4"
*Remember that the two numbers have to be the same since x is squared*
Again, we can use common knowledge and say that 2x2 is equal to 4
This means that x=2
Now when you square a variable, the variable can have to values, a positive, and a negative value
So in this case, the other value for x would be x=-2 since -2 squared is also equal to 4
So we can come to a conclusion that
x=2
AND
x=-2
What is the circumcenter of ΔABC, if A(-7, 3); B(9, 3); and C(-7, -7)?
Answer: (1,-2)
Step-by-step explanation:
Sarah has two sets of cards. The first set of 26 cards is labeled with all the letters of the English Language. The second set of 10 cards is numbered 0 through 9.
If Sarah draws one lettered card and one numbered card at random, what is the probability of her drawing a letter in her name and an odd number? (Enter answer as a reduced fraction).
Answer:
1/13
Step-by-step explanation:
Probability of Sarah drawing a letter in her name
= number of letters in her name: S, A, R and H / total number of letters
= 4/26
Probability of drawing an odd number
= odd numbers / total numbers
= 5/10
Combining the above, Probability of her drawing a letter in her name and an odd number = 4/26 * 5/10
= 1/13
Total Alphabetical cards Sarah has ⇢ 26
Total Letters Sarah's name has ⇢ 4
Probability of getting a card with one of the letter in her name ⇢ 4/26
Total numerical Cards Sarah has ⇢ 10
Total odd numbers in those cards⇢5
Probability of getting a card with an odd number⇢ 5/10
probability of her drawing a letter in her name and an odd number⇢ 4/26 x 5/10 = 1/13
What type of triangle is a 30, 40, 50
Answer:
Pythagoras's Theorem states that the square of the length of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the lengths of the other two sides. Actually a 30 , 40 , 50 triangle is just a scaled up 3 , 4 , 5 triangle, which is a well known right angled triangle

Find the area of the missing square off of leg a if the area of one square is 369 and the area of another is 81.
A - 19.2
B - 144
C- 12
D- 288
Solution:
Note that:
Area of square = s² (s = Side length)Finding the leg of a square with area of 369 units²
c² = 369=> c = √369 unitsFinding the leg of a square with area of 81 units²
b² = 81=> b = √81 = 9 unitsFinding side length a using Pythagoras theorem
(√369)² = 9² + a²=> 369 = 81 + a²=> 369 - 81 = a²=> 288 = a²=> a = √288 = √144 x 2 = √12 x 12 x 2 = 12√2 unitsFinding the missing area of the square.
Area of square = a²=> Area of square = a² = (a)²=> Area of square = (12√2)²=> Area of square = (12√2)(12√2) = 288 units²Option D is correct.

The quadratic function, f(x )or g(x) has the greater maximum value ??
Answer:
The quadratic function, f(x) has the greater value.
Step-by-step explanation:
The given function written to us is in standard form, meaning it is easy to graph this function.
Since this function is going to open down-ward, we start with negative numbers.
[tex]f(-1)=3\\[/tex]
Since 3 is a greater value than 2, which we can see is the maximum value of g(x) by viewing the graph, f(x) is greater.

Answer:
175/24
Step-by-step explanation:
First change mixed fraction to improper fraction.
1¾= (1×4+3)/4
= 7/4
4⅙= (4×6+1)/6
= 25/6
now multiply the nominators (numbers on the top) and then the denominators (numbers on the bottom)
I.e
7/4 × 25/6
= 7×25/4×6
= 175/24
it cannot be further simplified so 175/24 is the answer.

Find that the point at which the line intersects with the line y = 0 is (3, 0).
Find that the point at which the line intersects with the line x = y is (2, 2).
Answer:
Step-by-step explanation:
its A :)
Answer= y=2x+6
The slope-intercept form of an equation of a line: y=mx+b
m - slope
b - y-intercept
We have the points (5, -4) and (-1, 8). Substitute:
m= [tex]\frac{8-(-4)}{-1-5}[/tex] =[tex]\frac{12}{-6}[/tex] =-2
Put the value of the slope and the coordinates of the point (5, -4) to the equation of a line,
-4=-2(5)+b
=-10+b
6=b
y=2x+6

The total remodeling budget for Central Square Tower is 1.5×106 dollars. The owners of the building have set aside 6×105 dollars for upgrading just the lobby. What percent of the budget will be spent on the lobby? Write your answer in standard form. Do not write exponents.
Answer:
40%
Step-by-step explanation:
assuming you actually mean 10^5 and 10^6, to find percentages you do
part/total x percent/100
you have (6x10^5/1.5x10^6) x (x/100)
cross multiply, and you have 6x10^7=1.5x10^6x
divide on both sides by 1.5x10^6
x=40
so the answer is 40%
9. Find the area of the figure.
What is the answer
Answer:
73.12 in.²
Step-by-step explanation:
The entire area is made up of a semicircle and a rectangle. We find both areas and add them.
total area = area of semicircle + area of rectangle
total area = (1/2)πr² + length × width
total area = 1/2 × 3.14 × 4 in. × 4 in. + 8 in. × 6 in.
total area = 73.12 in.²

The circumference of a circle is 7.5. What is it’s diameter?
45:60 as its simplest form
Answer :
3/4.
Explanation
Find the GCD (or HCF) of numerator and denominator
GCD of 45 and 60 is 15
Divide both the numerator and denominator by the GCD
45 ÷ 15
60 ÷ 15
Reduced fraction: 3/4
Therefore, 45/60 simplified to lowest terms is 3/4.
Hi! I hope you are enjoying your day!
In order to simplify this ratio (and 45:60 is a ratio), we should divide both sides of the ratio by 5 (because both 45 and 60 are evenly divisible by 5)
Divide:
9:12
Is the ratio in its simplest form? No.
Why?
Because 9 and 12 can be divided by 3:
3:4
Now the ratio IS in its simplest form.
Hence, the answer is
[tex]\boxed{\boxed{\bold{3:4}}}[/tex]
Hope everything is clear.
