Answer:

64 left handed girls

25 left handed boys

89 total left handed students

Step-by-step explanation:

Multiply 320 x 0.2

Multiply 250 x 0.1

You can think of it this way, 0.2 is 2/10 and 0.1 is 1/10 so take 20 percent of 320 and 10 percent of 250

Add them up for your answer 64 + 25 = 89

The lengths of the sides of the right triangle that is formed are x-h and y - k

The triangle contained within the circle is a right angled triangle with the longest side as the hypotenuse.

Given the coordinate points (h, k) and (x, y), the lengths of the sides of the right triangle is equal to the difference between the x-ccordinate points and y-coordinate points

For the x-coordinstes

a = x - h

For the y-coordinate

b = y - k

Hence the lengths of the sides of the right triangle that is formed are x-h and y - k

Step-by-step explanation:

Answer:

Volume of rectangular tank = 6 cubic feet

Step-by-step explanation:

Length of the rectangular tank = 3 feet

Width of the tank = 1 feet

And height of the rectangular tank = 2 feet

Since, tank is in the shape of a cuboid,

Volume of a cuboid = Length × Width × height

                                 = 3 × 1 × 2

                                 = 6 cubic feet

Therefore, volume of the rectangular tank will be 6 cubic feet.

Answer:

BC = 10 units

Step-by-step explanation:

From the picture attached,

It's given that AD and BE are the parallel sides.

AC and DC are the transversal lines intersecting the parallel lines.

In ΔADC and ΔBEC,

∠DAC ≅ ∠EBC [Corresponding angles]

∠ADC ≅ ∠BEC [Corresponding angles]

ΔADC ~ ΔBEC [By AA property of similar triangles]

By the property of similar triangles,

Corresponding sides of the similar triangles are proportional.

[tex]\frac{AC}{BC}=\frac{DC}{EC}[/tex]

[tex]\frac{AB+BC}{BC}=\frac{DE+EC}{EC}[/tex]

[tex]\frac{2.5+BC}{BC}=\frac{2+8}{8}[/tex]

[tex]\frac{2.5}{BC}+1=\frac{10}{8}[/tex]

[tex]\frac{2.5}{BC}=\frac{5}{4}-1[/tex]

[tex]\frac{2.5}{BC}=\frac{1}{4}[/tex]

BC = 10

Answer: 8 patties

Step-by-step explanation:

There are 2 pounds of beef and Neil wants to use these to make patties that are 1/4 pounds each.

The number of patties that can be made are:

= Pounds of meat available ÷ Pound needed per patty

= 2 ÷ 1/4

= 2 * 4/1

= 8 patties

Answer:

$4.64

Step-by-step explanation:

$42 x tax rate = 3.36

tax rate = 3.36/42

tax rate = 8%

Answer:

The measure of angle E is 45 degrees

Step-by-step explanation:

To get the measure if angle E, we use the appropriate trigonometric ratio

From the question, EF is the hypotenuse since it faces the right angle

EG is adjacent to angle E

so we are going to use the trigonometric ratio that connects adjacent to the hypotenuse

This trigonometric ratio is the cosine

It is the ratio of the adjacent to the hypotenuse

Thus,

we have it that;

Cos E = EG/EF

cos E = 6√26/12√13

E = arc Cos ( 6 √26/12 √13)

E = 45 degrees

Answer:

The angle is 1/4 the circumference is the arc

Step-by-step explanation:

To solve this, we are to set up a fractional relation between the central angle subtended by the arc and the total angle subtended by the circle.

At this point, we can note that the circumference of a circle actually subtends an angle of 2π radians at the center.

To express the angle subtended by the central angle [angle at the centre of the arc] as a fraction of the total circle, we do this:

The central angle of arc / total angle at the centre of the circle

= π/2 ÷2π

=[tex]\pi/2 \times \frac{1}{2\pi}= 1/4[/tex]

Therefore the angle is 1/4 the circumference is the arc

Answer:

The coordinates of the vertices of triangle A'B'C' are [tex]A'(x,y) = (0,-4)[/tex], [tex]B'(x,y) = (2,-1)[/tex] and [tex]C'(x,y) = (3,-5)[/tex].

Step-by-step explanation:

According to this statement, triangle ABC must be translated 5 units in the -y direction to form triangle A'B'C'. We need to use the following operations:

[tex]A'(x,y) = A(x,y) +(0,-5)[/tex] (1)

[tex]B'(x,y) = B(x,y) +(0,-5)[/tex] (2)

[tex]C'(x,y) = C(x,y) + (0,-5)[/tex] (3)

If we know that [tex]A(x,y) = (0,1)[/tex], [tex]B(x,y) = (2,4)[/tex] and [tex]C(x,y) = (3,0)[/tex], then the new  vertices of the rectangle are, respectively:

[tex]A'(x,y) = (0,-4)[/tex], [tex]B'(x,y) = (2,-1)[/tex], [tex]C'(x,y) = (3,-5)[/tex]

Given:

The statement is "Five times the difference of the cube of y and the square of x".

To find:

The algebraic expression for the given statement.

Solution:

We know that,

Cube = Power 3

Square = Power 2

Difference = Minus (-)

Times = Multiplication (×)

Now,

Cube of y = [tex]y^3[/tex]

Square of x = [tex]x^2[/tex]

Difference of the cube of y and the square of x = [tex]y^3-x^2[/tex]

Five times the difference of the cube of y and the square of x is:

Required expression = [tex]5(y^3-x^2)[/tex]

Therefore, the correct option is C. The required algebraic expression for the given statement is [tex]5(y^3-x^2)[/tex].
