Jada volunteers at an animal shelter that holds picnics to introduce people to animals. For the first picnic, she brought 36 clementines for 16 people, which was the right amount. For the next picnic, there will be 40 people!
How many clementines should Jada bring for all those people? Explain or show your reasoning.
Jada would have brought 90 clementines for all those people.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
For 40 people number of clementines be x,
So, as for the proportional relationship.
16 / 36 = 40 / x
x = 40 [36/16]
x = 10[9]
x = 90
Thus, Jada would have brought 90 clementines for all those people.

is it possible for two triangles to have the same angle measures but not be congruent?explain.
Answer:
Yes
Step-by-step explanation:
One triangle can be bigger then another and still have the same angle measure.
Yes, it is possible for two triangles to have the same angle measures but not be congruent.
What is congruency?If two triangles are congruent, this means they are the same shape and the same size.
One triangle can be bigger than another and still have the same angle measure. For example, if there are two equilateral triangles all the angles are 60 degrees.
But one triangle is having a side of 10 units and the other triangle is having a side of 20 units means the second triangle is bigger than the first but the angle for both the triangles is 60 degrees.
Therefore, it is possible for two triangles to have the same angle measures but not be congruent.

What is the vertical distance between 580ft above sea level and 200ft below sea level. Help
Answer:
780ft Hope i helped <3
Step-by-step explanation:
Answer:
780 ft
Step-by-step explanation:
you have to think of it as adding the two and not subtracting because they are asking the total distance. The first one is above sea level so it's 580 above sea level. the second one is under sea level so 200 ft under sea level. that means that the total distance if we start from under the sea 200 ft up to the sea level and then another 580 ft to above sea level!
Your promotional budget for the year is $300 for personal selling, $300 for sales promotion, \$1,500 for advertising, and $500 for image promotion. What is your total promotional budget for this year?
a) $2,000
b) $2,600
c) $3,600
d) $4,600
Answer:
to get the total promotion budget for the year we will add $300 for personal selling plus $300 for sales promotion plus $1500 for advertising plus $500 for image promotion to the a total of 2600 dollars
The total promotional budget for this year should be considered as the $2,600.
Calculation of the total promotional budget:Since there is $300 for personal selling, $300 for sales promotion, \$1,500 for advertising, and $500 for image promotion.
So,
= $300 + $300 + $1,500 + $500
= $2,600

Here all the given equations are in the form of
[tex]ax^2+bx+c=0[/tex]
The value of [tex]x[/tex] can be determined by the perfect square method as follows:
[tex]ax^2+bx+c=0[/tex]
[tex]\Rightarrow x^2+\frac{b}{a}+\frac{c}{a}=0[/tex]
[tex]\Rightarrow x^2+2\times\frac{b}{2a}+\left(\frac{b}{2a}\right)^2-\left(\frac{b}{2a}\right)^2+\frac{c}{a}=0[/tex]
[tex]\Rightarrow \left(x+\frac{b}{2a}\right)^2=\left(\frac{b}{2a}\right)^2-\frac{c}{a}[/tex]
[tex]\Rightarrow x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\;\cdots(i)[/tex]
Now, for [tex]x^2+3x-4=0[/tex]
[tex]a=1, b=3, c=-4[/tex]
So, from equation (i)
[tex]x=\frac{-3\pm\sqrt{3^2-4\times1\times(-4)}}{2\times1}[/tex]
[tex]\Rightarrow x=\frac{3\pm\sqrt{9+16}}{2}[/tex]
[tex]\Rightarrow x=\frac{3\pm5}{2}[/tex]
[tex]\Rightarrow x=\frac{3+5}{2},\frac{3-5}{2}[/tex]
[tex]\Rightarrow x= 4, -1[/tex]
Similarly, for [tex]9x^2+12x+4=0[/tex]
[tex]a=9, b=12, c=4[/tex]
So, from equation (i)
[tex]x=\frac{-12\pm\sqrt{12^2-4\times9\times4}}{2\times9}[/tex]
[tex]\Rightarrow x=\frac{-12\pm0}{18}[/tex]
[tex]\Rightarrow x=\frac{-2}{3}[/tex]
For [tex]x^2-2x-3=0[/tex]
[tex]a=1, b=-2, c=-3[/tex]
[tex]x=\frac{-(-2)\pm\sqrt{(-2)^2-4\times1\times(-3)}}{2\times1}[/tex]
[tex]\Rightarrow x=\frac{2\pm\sqrt{16}}{2}[/tex]
[tex]\Rightarrow x=\frac{2\pm4}{2}[/tex]
[tex]\Rightarrow x=\frac{6}{2},\frac{-2}{2}[/tex]
[tex]\Rightarrow x=3.00, -1.00[/tex]
For [tex]x^2-6x+9=0[/tex]
[tex]a=1, b=-6, c=9[/tex]
[tex]x=\frac{-(-6)\pm\sqrt{(-6)^2-4\times1\times9}}{2\times1}[/tex]
[tex]\Rightarrow x=\frac{6\pm0}{2}[/tex]
[tex]\Rightarrow x=3.00[/tex]
For [tex]2x^2-4x-3=0[/tex]
[tex]a=2, b=-4, c=-3[/tex]
[tex]x=\frac{-(-4)\pm\sqrt{(-4)^2-4\times2\times(-3)}}{2\times2}[/tex]
[tex]\Rightarrow x=\frac{4\pm\sqrt{40}}{4}[/tex]
[tex]\Rightarrow x=\frac{4\pm2\sqrt{10}}{4}[/tex]

What is the measure of the angles below?* 8x-3 6.x + 17
Answer:
x = 10
Step-by-step explanation:
Simplifying
8x + -3 = 6x + 17
Reorder the terms:
-3 + 8x = 6x + 17
Reorder the terms:
-3 + 8x = 17 + 6x
Solving
-3 + 8x = 17 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
-3 + 8x + -6x = 17 + 6x + -6x
Combine like terms: 8x + -6x = 2x
-3 + 2x = 17 + 6x + -6x
Combine like terms: 6x + -6x = 0
-3 + 2x = 17 + 0
-3 + 2x = 17
Add '3' to each side of the equation.
-3 + 3 + 2x = 17 + 3
Combine like terms: -3 + 3 = 0
0 + 2x = 17 + 3
2x = 17 + 3
Combine like terms: 17 + 3 = 20
2x = 20
Divide each side by '2'.
x = 10
Simplifying
x = 10

Cabletown charges $5 signup fee and a $0.50 charge per video.
Networkflicks charges a $12 signup fee and a $0.15 charge per video. How
many videos do you need to watch in a month for the two companies to cost
the same?
Given parameters:
Signup fee for Cabletown = $5
Charge per video = $0.50
Sign up fee for Networkflicks = $12
Charge per video = $0.15
Unknown:
The number of videos watched in which the cost of both months will be thesame = ?
Solution:
Let the number of videos= x
Now let us set up algebraic equations to solve this problem;
5 + 0.5x = 12 + 0.15x
Collect like terms and solve;
5 - 12 = 0.15x - 0.5x
-7 = -0.35x
x = 20
The number of videos watched will be 20 videos

Gradient = Slope = coefficient of x
Thus ;
Gradient = Slope = 5

Vertical axis = y -axis
To find the y-intercept of the equation we must put zero instead of x .
Let's do it.....
[tex]y = 5x + 30[/tex]
[tex]y = 5(0) + 30[/tex]
