the answer is 313

Step-by-step explanation:

Answer: B does not belong with the others. The others are all right triangles, while B is an obtuse triangle. It might be wrong if they're looking for something different though.

Step-by-step explanation:

The two triangles are similar if the ratio of the corresponding sides are equal.

Ratio is a mathematical comparison of two or more quantities expressed as a fraction. A ratio can be expressed as a fraction, a decimal, or in the form of words. Ratios are used to compare items or quantities in a variety of different contexts, from mathematics and science to business and daily life. For example, a ratio of 2:1 indicates that for every two items, there is one of the same item.

This means that the ratio of side AB to side DE must be equal to the ratio of side BC to side EF, and the ratio of side AC to side DF must be equal to the ratio of the remaining sides.
For example, if side AB is 10 cm and side DE is 5 cm, then side BC must be 10 cm and side EF must be 5 cm for the two triangles to be similar. Similarly, if side AC is 8 cm and side DF is 4 cm, then the remaining sides must be 8 cm and 4 cm respectively.

Answer:

base = 519.62, height = 173.21 m

Step-by-step explanation:

Let the base and height of the triangle be represented by b and h respectively.

Thus,

b = 3h

Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height

For the given triangle,

area = [tex]\frac{1}{2}[/tex] x b x 3h

       = [tex]\frac{3}{2}[/tex]bh

Area of the triangle = [tex]\frac{3}{2}[/tex]bh

To determine the number of hectares,

36 per hectare = 486

hectare = [tex]\frac{486}{36}[/tex]

             = 13.5

numbers of hectares = 13.5

Area of the hectares = number of hectares x 10 000 m²

                                   = 13.5 x 10 000

                                  = 135000

Total area of the hectares = 135 000 m²

So that,

area of the hectares = area of the triangle

area of the triangle = [tex]\frac{3}{2}[/tex]bh

135 000 = [tex]\frac{3}{2}[/tex]bh

270000 = 3bh

bh = [tex]\frac{270000}{3}[/tex]

     = 90000

bh = 90000

But, b = 3h

3h x h = 90000

3[tex]h^{2}[/tex] = 90000

[tex]h^{2}[/tex]  = [tex]\frac{90000}{3}[/tex]

     = 30000

h = [tex]\sqrt{30000}[/tex]

  = 173.2051

h = 173.21 m

So that,

b = 3 x 173.2051

  = 519.6153

b = 519.62

Therefore, the base of the triangle is 519.62 m, while the height is 173.21 m.

Given:

The triangle PQR on a coordinate plane.

To find:

The image of point Q after a rotation of 90° counterclockwise about the origin.

Solution:

From the given graph, it is clear that the coordinates of point Q are (5,0).

If the figure is rotated 90° counterclockwise about the origin, then the rule of rotation is defined as

[tex](x,y)\to (-y,x)[/tex]

Using this rule, we get

[tex]Q(5,0)\to Q'(-(0),5)[/tex]

[tex]Q(5,0)\to Q'(0,5)[/tex]

So, the image of point Q is (0,5).

Therefore, the correct option is (a).

Answer:

JD is wrong.

Although, the volume of the cube shaped box V' = 421.88 in³  > volume of the sphere V = 268.1 in³, the sphere cannot fit into the box because its diameter, d = 8 in > side of cube = 7.5 in.

Step-by-step explanation:

The sphere would only fit into the cube shaped box if its diameter is less than the length of side of the cube L = 7.5 inches.

So, diameter of sphere d = 2r where r = radius of sphere = 4 inches. Thus, d = 2r = 2(4 in) = 8 in.

Since the diameter of the sphere d = 8 inches > length of side of the cube = 7.5 inches, the sphere would not fit into the box.

So, JD is wrong.

We calculate both the volume of the sphere and cube.

Volume of a sphere V = 4πr³/3 where r = radius of sphere = 4 inches

So, V = 4πr³/3

= 4π(4 in)³/3

= 4π(64) in³/3

= 256π in³/3

= 804.25 in³/3

= 268.1 in³

Volume of a cube V' = L³ where L = length of side of cube = 7.5 inches

So, V' = L³

= (7.5 in)³

= 421.88 in³  

Although, the volume of the cube shaped box V' = 421.88 in³  > volume of the sphere V = 268.1 in³, the sphere cannot fit into the box because its diameter, d = 8 in > side of cube = 7.5 in.

Answer:

DHGB

Step-by-step explanation:

Let's start with 1.  

The equation is in standard form (ax+by=c): -4x+2y=8

we'll put it into slope intercept form.

Add 4x onto both sides

2y=4x+8

divide by 2

y=2x+4

Parallel lines have the same slope, but a different y intercept. (the line parallel to this one will have a slope of 2 but a y intercept different from +4)

Looking at the answer choices, the only choice with a slope of 2 is D (y=2x-5)

So the answer to 1  is D

Now 2.

we're given 3 points. One of the points crosses the y axis, which is the y intercept. In this case, the line crosses the point (0,3)

That means the y intercept of the line is (0,3)

here's the line so far:

y=mx+3 (m is a placeholder for the slope)

when given a graph, we can use rise/run. Starting from the point (3,2), we can move 3 spaces to the left, and one up.

In a graph, if you move to the left or downwards, it's a negative move. If you move up or to the right, it's a positive move.

Since we went 1 space up (rise) and 3 spaces to the left, (run) the slope is -1/3

So the line is y=-1/3x+3

Perpendicular lines are negative and reciprocal. If you multiply their slopes, they will equal -1. Their y intercepts don't matter at all.

So to find the slope, we can use this equation.

-1/3m=-1

multiply by -3 on both sides

m=3

Looking at the answer choices, H is the only answer with a slope of 3. So the answer to 2 is H.

Now, 3

You can do the graph method like above for 2, but I'll just calculate the slope.

We're given two points, (-1,-2) and (0,2)

the formula for slope is (y2-y1)/(x2-x1)

we can label the points.

x1=-1

y1=-2

x2=0

y2=2

now, substitute into the equation.

m=(2--2)/(0--1)

m=4/1

the slope is 4.

Now let's use point slope form, which is y-y1=m(x-x1)

once again, sub. into the equation.

y+2=4(x+1)

do distributive prop

y+2=4x+4

subtract by 2

y=4x+2

As said above, parallel lines have the same slope.

Looking at the answer options, G also has the slope of 4

so the answer to 3 is G

Finally, #4

Equation: 3x+y=1

subtract 3x from both sides

y=-3x+1

As said above, perpendicular lines have slopes that multiply to equal -1.

-3m=-1

multiply by -1/3

m=1/3

so the slope of the line will be 1/3.

Looking at the answer options, B also has a slope of 1/3.

So the answer to 4 is B

The code is DHGB
