How do you work this out

pogonyaev

Okay, I can’t really see all of the pictures completely but I’ll try my best to help.

For the page with the equivalent fractions, the answers are:
1/2 = 5/10
3/4 = 9/12
4/10 = 2/5
1/4 = 2/8

I would love to help more but I need more pictures to see the whole problem. I was going to try and help with the sequence problems but I can’t see it.

Anyways, I hope that this helps!

Nikki drew a rectangle with a perimeter of 18 units on a coordinate grid. Two of the vertices were (4, –3) and (–1, –3). What co

Talja [164]

Answer:

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Step-by-step explanation:

Geometrically speaking, the perimeter of a rectangle ( $p$ ) is:

$p = 2\cdot b + 2\cdot h$ (1)

Where:

$b$ - Base of the rectangle.

$h$ - Height of the rectangle.

Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:

$b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}$

$b = 5$

If we know that $p = 18$ and $b = 5$ , then the height of the rectangle is:

$2\cdot h = p-2\cdot b$

$h = \frac{p-2\cdot b}{2}$

$h = \frac{p}{2}-b$

$h = 4$

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Mrs. White paid $946.50 for five plane tickets. How much did each plane ticket cost?

lakkis [162]

Answer:

Each plane ticket was $189.3

Step-by-step explanation:

If all tickets were at the same price, and for five tickets the person paid $946.50, then to find out how much was each ticket, we simply have to divide this quantity by 5:

$946.5 / 5 = $189.3
