Answer:

a. 24/60 = 40%

b. 24/60 = 40%

Explanation:

it seems both the questiona have the same answer. how many students in the competition is what you are looking for, the total of people in the competition is 60(36+24). there are 24 students, so you divide 24 by 60 and you will get 40% for both questions.

Answer:

y=-3x

Step-by-step explanation:

The y intercept is zero because it goes through (0,0)

The slope is -3 because the line goes through -3 at 1, so it goes down 3 on the y axis for every 1 right on the x axis.

Answer:

Margo will pay $ 44 in interest.

Step-by-step explanation:

Given that Margo borrows $ 1600, agreeing to pay it back with 3% annual interest after 11 months, to determine how much interest will she pay, the following calculation must be performed:

3/12 x 11 = 0.25 x 11 = 2.75

1600 x 1.0275 = X

1644 = X

1644 - 1600 = 44

Therefore, Margo will pay $ 44 in interest.

64+36=100

Square root of 100=10

Answer:

87 many more plums are there in Basket A than Basket B

Step-by-step explanation:

Before

N = 58/2

Basket A = N x 7 + 58

Basket B = N x 7

Now

Basket A = 29 x 7 + 58

= 261/3

= 87

Basket B =  29 x 7

= 203 + 58

= 261/3

= 87

Basket A and B has a difference of 87 Plums

15/25 = 3/5

Answer:

3

Step-by-step explanation:

[tex]\frac{15}{25} =\frac{?\\}{5}[/tex]      25 divided by ? = 5? The number 5 so divide 15 as well

15 ÷ 5 = 3

[tex]\frac{15}{25} =\frac{3}{5}[/tex]

Answer:

The graph represents a linear function that passes through the origin.

Step-by-step explanation:

Proportional functions can be represented by [tex]y=kx[/tex], where [tex]k[/tex] is some constant. They form a straight line that always pass through the origin (0,0). We can see all these characteristics in the graph, thus the graph is proportional.

Answer:

option 2

Step-by-step explanation:

[tex]y - 8 = \frac{1}{2} (x - 4)\\\\y = \frac{1}{2}x - 2 + 8\\\\y = \frac{1}{2}x + 6\\\[/tex]

Kenny recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  y-x-4  = 0 and calculate its properties

Answer:1st cube 2nd box 2nd cube 3rd box 4th cube 1st box and 1st cube 1st box

Step-by-step explanation:

The asked volumes are 36/125 cm³, 6/125 cm³, 1/125 cm³ and 8/125 cm³

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.

Given are dimensions of cuboid and cubes, we are asked to find their volumes.

We know that, volume of cube = side³

Volume of cuboid = length · width · height

1) Dimensions of the cuboid = 3/5, 4/5, 3/5

Volume = 3/5×3/5×4/5 = 36/125 cm³

2) Dimensions of the cuboid = 1/5, 2/5, 3/5

Volume = 1/5×2/5×3/5 = 6/125 cm³

3) Side of the cube = 1/5 cm

Volume = (1/5)³ = 1/125 cm³

4) Side of the cube = 2/5 cm

Volume = (2/5)³ = 8/125 cm³

Hence, the asked volumes are 36/125 cm³, 6/125 cm³, 1/125 cm³ and 8/125 cm³

I hope this is help full to you

Answer:

The length is 7 meters

Step-by-step explanation:

Formula: P = 2L + 2W

Plug in 24 for the perimeter and 5 for the width

New equation: 24 = 2L + 2(5)

Simplify: 24 = 2L + 10

Subtract 10 from both sides: 24 - 10 = 2L + 10 - 10

Simplify: 14 = 2L

Divide both sides by 2: L = 7

Answer: L = 7

Answer:

[tex]\text{B. } (8,6)[/tex]

Step-by-step explanation:

In slope-intercept form [tex]y=mx+b[/tex]:

In slope-intercept form, the equation for the table is given by [tex]y=x-2[/tex], and the equation for the second line is given by [tex]y=\frac{1}{4}x+4[/tex].

To find the point of intersection, set those two equations equal to each other and solve:

[tex]x-2=\frac{1}{4}x+4,\\x-2=0.25x+4,\\0.75x=6,\\x=8[/tex]

[tex]y=x-2,\\y=8-2,\\y=6[/tex]

Therefore, these two lines intersect [tex]\boxed{\text{B. (8,6)}}[/tex]

Answer:

a = 158.3 units²

Step-by-step explanation:

a = (∅/360) * πr²

using 11 ft as the radius

a = (150/360) * 3.14 * 11²

a = 158.3 units²

Answer:

the answer will be Root 2

Step-by-step explanation:

x^2 = 1^2 + 1^2

We take the unmentioned side as 1 because it is an isosceles triangle and thus 2 of the sides will have the same measure

x^2 = 1 + 1

x^2 = 2

taking square root on both the sides

x = root of 2

The value of  x is [tex]\sqrt 2[/tex]  by using the concept of isosceles right-angled triangle and applying the Pythagoras theorem.

Given that in a right-angled triangle, base is equal to1 and hypotenuse is equal to x.

To find the value of x by using the concept of isosceles right-angled triangle and applying the Pythagoras theorem, follow steps:

Step 1: Given right-angled triangle whose two angles are of equal measures that is equal to [tex]45^{\circ}[/tex]. That implies the triangle is an isosceles triangle.

That implies, perpendicular = base  = 1 .

Step 2: Applying the concept of Pythagoras theorem:

Pythagoras theorem states that (perpendicular[tex]{)}^2[/tex] +(base[tex]{)}^2[/tex] = (hypotenuse[tex]{)}^2[/tex]

Plugging the given and data from step 1 gives:

[tex](1)^{2}+1^2=x^{2}[/tex]

On substituting the square of 1 equal to 1 (gives):

[tex]x^{2} = 1+1[/tex]

On adding gives:

[tex]x^{2} =2[/tex]

Taking square root gives:

[tex]x=\sqrt{2}[/tex]

Therefore, the value of  x is [tex]\sqrt 2[/tex]  by using the concept of isosceles right-angled triangle and applying the Pythagoras theorem.

Answer:

If you have a general point (x, y), and you reflect it across the x-axis, the coordinates of the new point will be:

(x,-y)

So we only change the sign of the y-component.

Now, if we do a reflection across the x-axis of a whole figure, then we apply the reflection to all the points that make the figure.

Then, we could just apply the reflection to the vertices of the square, then graph the new vertices, and then connect them, that is equivalent to graph the image of the square after the reflection.

The original vertices are:

C = (-3, 7)

D = (0, 7)

E = (0, 10)

F = (-3, 10)

Now we apply the reflection, remember that this only changes the sign of the y-component, then the new vertices are:

C' = (-3, -7)

D' = (0, -7)

E' = (0, - 10)

F' = (0, - 10)

Now we need to graph these points and connect them to get the reflected figure, the image can be seen below.
