Answer:
I think it is 8 (not %100 sure)
Step-by-step explanation:
what I did was I divided 40 by 5 which gave me 8
I hope this helps;) sorry if it dosen't
Answer:
The Answer Is 10
Step-by-step explanation:
The Total Strength = 40 Students
The Ratio Of Boys To Girls = 3:5
So, 3 + 5 = 8
Then, Divide 8/40 So That U Get The Number Then Multiply It With The Ratio.
•8/40 = 5
•5 × 3 = Boys Strength Which Is = 15
•5 × 5 = Girls Strength Which Is = 25
So, There Are 10 Girls More Than Boys.
Hope It Helps U.

Answer:
5x^2-4+4(x^2)-6x
Step-by-step explanation:
first you need to remove the unnecessary parentheses it should look like this: 5x^2-7-(4(x^2)+6x-3)
then you should calculate the sum it should look like this: 5x^2-4+4(x^2)-6x and that is your answer

On Sunday, Sheldon bought 4 1 2 kg of plant food. He used 1 2 3 kg on his strawberry plants and used 1 4 kg for his tomato plants. How many kilograms of plant food did Sheldon have left? Write one or more equations to show how you reached your answer.
Answer: 2 1/2kg
Step-by-step explanation:
Weight of plant food bought = 4 1/2kg
Amount used on strawberry plant = 1 2/3kg
Amount used on tomato plant = 1/4kg
Therefore, the amount used will be:
= 1 2/3 + 1/4
= 1 8/12 + 3/12
= 1 11/12kg
We then subtract the value gotten from the amount bought. This will be:
= 4 1/2 - 1 11/12
= 4 6/12 - 1 11/12
= 2 6/12
= 2 1/2kg
61 = r/3 − 7 a. 206 b.26 c.204 d.22 what is r? I will brainliest
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Simple maths.
Here,
61 = r/3 - 7
hence, r/3 = 61+7
===> r/3 = 68
==> r = 68*3
====> r = 204

Please help me with my algebra homework (Attachment)
Answer:
D.
Step-by-step explanation:
To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.
What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5
B.
left = -5 - 5 = -10
right = -(2/3)(4 + 4) = -16/3
So it's D. Let's verify:
D.
left = -5 + 5 = 0
right = -(2/3)(4 - 4) = 0
Checks out.
Answer:
Option D
Step-by-step explanation:
→ Find the gradient of the parallel line
[tex]y=-\frac{2}{3} x+c[/tex]
→ Substitute in the coordinates as x and y values to find c
[tex]5=-\frac{2}{3} *-4+c[/tex]
→ Simplify
[tex]5=\frac{8}{3} +c[/tex]
→ Minus [tex]\frac{8}{3}[/tex] from both sides to find c
[tex]c = \frac{7}{3}[/tex]
→ Expand out all options and then see which one contains all the numbers above
Option D

The vertex of a parabola is (1,3) and another point on the parabola is (-1,-1). Which point is also on the parabola?
A. (-3,3)
B. (0,3)
C. (3,-1)
D. (1,0)
Answer:
Step-by-step explanation:Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.
The vertex of a parabola is the point at the top or bottom of the parabola.
'h' is -6, the first coordinate in the vertex.
'k' is -4, the second coordinate in the vertex.
'x' is -2, the first coordinate in the other point.
At this point this one decides my grade
The circumference of a circle is 8π centimeters. What is the area of the circle in terms of π?
Answer:
A = 16π cm²
Step-by-step explanation:
We require to find the radius r
Given circumference C = 8π , then
2πr = 8π ( divide both sides by 2π )
r = 4 , then
A = πr² = π × 4² = 16π cm²
Answer:
A = 16π cm²

Write an equation of The line that passes through the given point and is parallel to the given line (4;5);y=-3/2x+3
9514 1404 393
Answer:
y = -3/2x +11
Step-by-step explanation:
The slope of the parallel line is the same as the slope of the given line, so ...
m = -3/2
The y-intercept of the parallel line can be found from ...
b = y -mx
b = 5 -(-3/2)(4) = 11
So, the desired equation is ...
y = mx +b
y = -3/2x + 11
_____
Additional comment
Since you know the slope and a point on the desired line, you can write down the equation directly using the point-slope form. No additional math is required.
y -5 = -3/2(x -4)
Find the value of a and b.
2x + 5y = 9
3x – 2y = 4
x= ?

i have 8 boxes of chocolate i eat 3 chocolates from each box i now have 72 chocolates in total
Answer: there were 12 chocolates in each box. (Originally, before any got eaten)
Step-by-step explanation: let x represent the total amount of chocolates in each box.
8x - 3(8) = 72
8x - 24 = 72 add 24 to both sides
8x = 96 divide both sides by 8
X = 12
Answer:
That means you had 48 chocolates in each box
Step-by-step explanation:
Since you eat 3 chocolates from all 8 boxes, you do this:
8 x 3 which = 24
Now since you have 72 chocolates left you do this:
72 - 24 which = 48
So, therefore, there were originally 48 chocolates in each box
(Don't eat so much chocolate lol you could get sick)
Make x the subject of the formula
x/3z = y-2
Answer:
x = 3z(y - 2)

What is the area of this shape? ANSWER AS FAST AS YOU CAN!!!!
Answer: 5x4x8x4x5x2x6x8x1
Step-by-step explanation:
Answer:
32 Square centimeters
Step-by-step explanation:
You have to seperate the shape into triangles and rectangles. if you do this, you get 2 identical triangles and 2 different rectangles. one of the rectangles is 8 square cm, the other is 12. you can see that the base of each of the 2 triangles is 3 cm long. 2 halves=1 whole, so the 2 triangles turn into 1 rectangle. therefore, you have to add 12+12+8. That is 32 square centimeters.
Hope my answer helped!
