The Amazon River, one of the
longest rivers in the world, is about 6,400 kilometers long. If 1 mile equals 1.6 kilometers, what is the length of the Amazon River in miles?

Answer:

D

Step-by-step explanation:

11 grams because the the most logical.

 Option C. 3 grams is the answer.

    Mass given,

For the balanced hanger diagram,

Mass on left arm = 2.(one triangle) + 6.(one square) + 3.(one circle)

Mass on right arm = 5.(one triangle) + 3.(one square) + 2.(one circle)

Equation for the balanced hanger,

2.(one triangle) + 6.(one square) + 3.(one circle) = 5.(one triangle) + 3.(one square) + 2.(one circle)

Now solve this equation,

(6 - 3).(one square) + (3 - 2).(one circle) = (5 - 2).(one triangle)

3.(one square) + 1.(one circle) = 3.(one triangle)

3.(2) + 1.(3) = 3.(one triangle)

6 + 3 = 3.(one triangle)

One triangle = 3 grams

    Therefore, Option (C) will be the correct option.

Answer: the scale factor is 1/2

And the missing side is 5.5

Step-by-step explanation:

The larger triangle is twice the smaller triangle

The scale factor is 1/2 and the length of the missings side is 5.5 after using the concept of the scale factor.

The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

It is given that:

The two rectangles are shown in the picture:

Part A what is the scale factor used when going from the larger rectangle to the smaller one?

The scale factor = 8/16 = 1/2

The length of the missings side = 1/2(11) = 5.5

Thus, the scale factor is 1/2 and the length of the missings side is 5.5 after using the concept of the scale factor.

2x9=18

6x9=54

54 boys to 18 girls

The number of boys who play kickball during breaktime is 54.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that, the ratio of boys to girls who play kickball during breaktime is 6 to 2, there are 18 girls on the team,

Let the number of boys be 6x and that of girls be 2x

Therefore, 2x = 18

x = 9

6x = 6*9 = 54

Hence, The number of boys who play kickball during breaktime is 54.

Lenght of the wire that supports the tree is, 6.5 feet

We have to given that,

A tree shown in image.

Here, Base length = 3.3 feet

And, Perpendicular length = 5.6 feet

Let us assume that,

Lenght of the wire that supports the tree = x

Hence, By definition of Pythagoras theorem we get;

x² = 5.6² + 3.3²

x² = 31.36 + 10.89

x² = 42.25

x = √42.25

x = 6.5 feet

Therefore, Lenght of the wire that supports the tree is, 6.5 feet

Answer:

72 in²

Step-by-step explanation:

The ratio of areas is proportional to the ratio of the square of the radii. The area of the larger dish is 72 square inches.

Important information:

Area of a small circular dish is 8 square inches.

The radius of the larger dish is tripled than the smaller dish.

We need to find the area of the larger dish.

Let [tex]r_1,r_2[/tex] are radius and [tex]A_1,A_2[/tex] are areas of smaller and larger dishes respectively.

[tex]\dfrac{(r_1)^2}{(r_2)^2}=\dfrac{A_1}{A_2}[/tex]

[tex]\dfrac{(r_1)^2}{(3r_1)^2}=\dfrac{8}{A_2}[/tex]

[tex]\dfrac{(r_1)^2}{9(r_1)^2}=\dfrac{8}{A_2}[/tex]

[tex]\dfrac{1}{9}=\dfrac{8}{A_2}[/tex]

On cross-multiplication, we get

[tex]A_2=9\times 8[/tex]

[tex]A_2=72[/tex]

Therefore, the area of the larger dish is 72 square inches.

Math

Way

The equations which have slope 1/4:

ii.  (y - 3.5) = 0.25(x - 2.75)

iii.  5x - 20y = 32

The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.

The slope-intercept form of a linear equation is y = mx + b, where m is the slope.

I. y = x - 5 is in slope-intercept form, so we can see that its slope is 1.

II. (y - 3.5) = 0.25(x - 2.75) can be rewritten in slope-intercept form as y = 0.25x + 2.1875. Therefore, its slope is 0.25 or 1/4.

III. 5x - 20y = 32 can be rewritten in slope-intercept form as y = (1/4)x - (4/5). Therefore, its slope is 1/4.

IV. 5x + 20y = 32 can be rewritten in slope-intercept form as y = (-1/4)x + (4/5). Therefore, its slope is -1/4.

So, only equations II, and III have a slope of 1/4.

Answer:

1 2/21

Step-by-step explanation:

We start out with:

3/7 + 2/3

In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:

3/21 + 2/21

But what about the numerators? You do the same thing as before (multiplying by the other's denominator).  Now we have:

9/21 + 14/21

We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:

1 2/21!
