Mathematics
1 answer:
Rama09 [41]2 years ago
6 0

Answer:

y=-2x+5

Step-by-step explanation:

Use the equation y=mx+b

We can find the b(y-intercept) by looking at the graph

The graph crosses the y-axis at (0,5)

We can look at the slope at the graph. We can see its down 4 over 2 so the slope is -2.

Plug that into the equation y=mx+b

y=-2x+5

What is the area of the following trapezoid in square feet?
tangare [24]

Answer:

82.5 ft²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h (b₁ + b₂)

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 7.5, b₁ = 7 and b₂ = 15 , then

A = \frac{1}{2} × 7.5 × (7 + 15) = 0.5 × 7.5 × 22 = 82.5 ft²

The distance around a circle is 37.7 meters long. what is the diameter of the circle?
aksik [14]
Ok so we know that the distance around the circle (or circumference) is equal to the diameter times pi.
This means that
37.7 = \pi \times d
d being the diameter,

This means that:
d =  \frac{37.7}{\pi}
= 12.00028271
= 12 m

So the diameter of the circle is 12 metres.

Hope this helped

Juan and Franco collect baseball cards. Juan has baseball cards. Franco has 18 fewer baseball cards than Juan. Together they hav
horsena [70]

Answer:

Franco has 66 baseball cards.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of baseball cards that Franco has.

y is the number of baseball cards that Juan has.

Franco has 18 fewer baseball cards than Juan.

This means that:

x = y - 18

Also:

y = x + 18

Together they have 150 baseball cards.

This means that:

x + y = 150

Since y = x + 18

x + x + 18 = 150

2x = 132

x = \frac{132}{2}

x = 66

Franco has 66 baseball cards.
