A 5 ounce can of peas cost $0.85. An 11 ounce can of peas cost $2.20. Which is the better buy?

Norma-Jean [14]

5 ounce of peas.

Explanation:

5 ounces of a can of peas is $0.85.
10 ounces of two cans of peas is $1.75.

10 is closer to 11.

So 5 ounces of a can of peas is more reasonable.

If f(x) = x2, which of the following describes the graph of f(x) - 5? A)The graph of f(x) - 5 is a vertical shift of f(x) = x2 f

lana [24]

F(x) = x^2 is a parabola with vertex at the origin (0,0).
f(x) = x^2 - 5 is a parabola shifted down 5 units so it's vertex would be at (0, -5)
The correct answer is Letter B

The distance light travels in one year is known as a light year. A light year is equal to 5.87 × 1012 miles. The closest that Ea

pashok25 [27]

Answer:

$6.21\times 10^{-5}\ \text{light years}$

Step-by-step explanation:

The distance light travels in one year is known as a light year.

$1\ \text{light year}=5.87\times 10^{12}\ \text{miles}$

The closest that Earth ever gets to Jupiter is $3.65\times 10^8\ \text{miles}$

$3.65\times 10^8\ \text{miles}=\dfrac{1}{5.87\times 10^{12}}\times 3.65\times 10^8\ \text{light years}\\\\=6.21\times 10^{-5}\ \text{light years}$

Hence, the distance it will take light to travel from Earth to Jupiter at this distance is $6.21\times 10^{-5}\ \text{light years}$

How much further up the wall does the ladder in figure 2 reach than

ASHA 777 [7]

The ladder in figure 2 reaches 3.2 feet further up than the ladder in figure 1.

Step-by-step explanation:

Step 1:

In both the given figures, the ladder, the wall and the floor form a right-angled triangle. The floor is the adjacent side, the wall is the opposite side and the ladder is the hypotenuse.

According to the Pythagorean theorem,

$a^{2}+b^{2}=c^{2}$ , where c is the length of the hypotenuse while a and b are the lengths of the other two sides.

Step 2:

For the ladder in figure 1, assume the distance from the floor to the ladder's top is x feet. So a = x, b = 8 and c = 10 (hypotenuse).

$a^{2}+b^{2}=c^{2}$ , $x^{2}+8^{2}=10^{2}$ , $x^{2}=100-64=36, x=\sqrt{36}=6 \text { feet }$ .

So the distance between the floor and the ladder's top is 6 feet.

Step 3:

For the ladder in figure 2, assume the distance between the floor and the ladder's top is y feet. So a = y, b = 4 and c = 10 (hypotenuse).

$a^{2}+b^{2}=c^{2}$ , $y^{2}+4^{2}=10^{2}$ , $y^{2}=100-16=48, x=\sqrt{84}=9.1651 \text { feet }$ .

So the distance between the floor and the ladder's top is 9.1651 feet.

Step 4:

The difference in heights = The wall height in figure 2 - the wall height in figure 1.

The difference in heights = 9.1651 feet - 6 feet = 3.1651 feet.

Rounding this off to the nearest tenth of a foot, we get 3.2 feet.

The opooste angles are equal

so
4y-8=79+y
minus y both sides
3y-8=79
add 8 both sides
3y=87
diide both sides by 3
y=29
