BaLLatris [955]2 years ago
5 0

Answer:

y = 5

Step-by-step explanation:

7(y + 2) – (4y – 10) = 44 – 2y + 5

(7y+14) - (4y - 10) = 49 -2y

3y +24 = 49 -2y

5y +24 = 49

5y = 25

y = 5

How to do this? pls don't ignore
oksano4ka [1.4K]
So basically you just need to do the Pythagorean theorem to find the sides of the shaded rectangle, with c being the length of the side.

Small side:
2^2 + 6^2 = c^2
4 + 36 = c^2
40 = c^2
C is similar to 6.32456

Long side:
12^2 + 4^2 = c^2
144 + 16 = c^2
160=c^2
C is similar to 12.64911

And then you just multiply!

The answer to that is 525 pounds in a week.

The question asks to find how many pounds of leaves 5 giraffes can eat in a week.

So multiply 525 pounds by 5 giraffes, and you get 2625 pounds of leaves.

How many times smaller is 4 x 10−7 than 3.5 x 10−4?
Tcecarenko [31]

The 875 times smaller is 4 x 10−7 than 3.5 x 10−4.

<h3>What is the arithmetic operator?</h3>

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given the two quantities 4 x 10−7 and 3.5 x 10−4

Now, if we divide this then

⇒ (3.5 x 10−4)/(4 x 10−7)

⇒ (35/40) × 10³

⇒ 875

Hence "The 875 times smaller is 4 x 10−7 than 3.5 x 10−4".
