Answer:
The whole candy is 400
The amount of red candies is unknown , let it be represented by y
To find the amount of red candy :
y= (32% of 400)
y = 32/100 × 400
y = 32×400/100
y= 32×4
y = 128
Therefore 128 candies are red

Answer:
Sin A = 5/13; tan C = 12/5
Step-by-step explanation:
Sin = opposite / hypotenuse. The opposite of A is 5, and the hypotenuse is 13, therefore Sin A = 5/13.
Tan = opposite / adjacent. The opposite of C is 12, and the adjacent is 5, so tan C = 12 / 5
find the slope of the line that passes through the given points (9, -3) and (9, 4)
Answer: No slope.

To the nearest hundreth, what is the length of line segment AB?
1.) 2.45
2.) 2.16
3.) 7.75
4.) 8.25
Answer:
option (4)
Step-by-step explanation:
Calculate the length using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A(2, 2) and (x₂, y₂ ) = B(- 6, 4)
AB = [tex]\sqrt{(-6-2)^2+(4-2)^2}[/tex]
= [tex]\sqrt{(-8)^2+2^2}[/tex]
= [tex]\sqrt{64+4}[/tex]
= [tex]\sqrt{68}[/tex]

Martha has two pet poodles. Fifi, her standard poodle, weighs 7 times as much as Buttercup, her toy poodle.
Pick the diagram that models the ratio in the story.
If Fifi weighs 56 pounds, how much does Buttercup weigh?
pounds
The diagram that models the ratio in the story is diagram A.
When fifi weighs 56 pounds, Buttercup will weigh 8 pounds.
What is a ratio?It should be noted that ratio demonstrates how many times one number can fit into another number. It contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data points.
Let buttercup be x
Let Fifi be 7x
Fifi weighs 56 pounds. This will be:
7x = 56
7x = 56
Divide
x = 56 / 7
x = 8
Buttercup is 8 pounds.

I am a 2-digit number. If sum of my two digits is added to the product of my digits, it is me again. Can you find me?
Answer:
Step-by-step explanation:
Let “ab” represent the digits of the number.
a ≠ 0
Value of the number = 10a+b
a+b + ab = 10a + b
a + ab = 10a
ab = 9a
b = 9
“ab” = 19, 29, 39, 49, 59, 69, 79, 89, 99
Answer: 49
Step-by-step explanation:
4x9=36

Answer:
4x + 2.5y = 184
x = y - 6
Step-by-step explanation:
Let the number of smoothies sold by stand = x
And number of cones sold = y
If the selling price of each cone = $2.5
Selling price of the 'y' cones = $2.5y
Selling price of each smoothies = $4
Then sales of smoothies = $4x
If the total sales of one day = $184
Equation for this situation will be,
4x + 2.5y = 184 -------(1)
If the stand sold 6 less smoothies than the cones,
x = y - 6 -----(2)
Therefore, system of equations contains two equations (1) and (2).

The hyperbola has two vertices at (-2,0) and (2,0)
We have given that the equation
[tex]\frac{x^2}{4}-\frac{y^2}{9}=1[/tex]
What is the equation of the hyperbola?[tex]\frac{x^{2} }{a^2}+\frac{y^2}{b^2} =1[/tex]
Compare the above equation of the hyperbola with given equation
therefore a=2
vertices are (-a,0) and (a,0)
Therefore the vertices are (-2,0) and (2,0)

Suppose a city with population of 400,000 has been growing at a rate of 5% per year. If this rate continues, find the population of this city in years.
The number of years value isn't given, we could use an hypothetical value, which can be substituted for the correct number of years given in your exercise in other to find the exact answer.
Using a t value of 10 years
Answer:
651558
Step-by-step explanation:
Given that:
Initial population, P0= 400,000
Growth rate, r = 5%
Using the relation :
P(t) = P0 * (1 + r)^t
t = number of years = 10
P(10) = 400000 * (1 + 0.05)^10
P(10) = 400000 * (1.05)^10
P(10) = 400000 * 1.628894626777
P(10) = 651557.8507
= 651558 nearest whole number.
Recall that, the t value used is hypothetical and should be replaces with te exact value given in your question.
