Answers

Answer 1
Answer:

Answer:

273

Step-by-step explanation:

65% is 65/100 or 13/20. So 13/20* 420/1. 420* 13 is 5460. 5460 divided by 20 is 273.

The mighty oak tree outside of Matt's house had to be cut down. He missed the beautiful tree and the shade it provided, and wanted to replace it with an oak tree that would grow quickly. The Nuttall Oak , the fastest growing oak tree, grows 5 to 6 feet per year (we'll assume it grows at a constant rate). At maturity, it can be up to 65 feet tall.Which of the following equations, where t represents time in years and h represents height in feet, describe growth that is FASTER than the Nuttall Oak growth rate?

Answer:

h=5t

This means the correct answer is A

Make X the subject of the formula y = ax + b

Answers

The linear equation can be written in the form of a, b, and y as x = (y - b)/a if the linear equation is y = ax + b.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The linear expression is:

y = ax + b

The linear expression can define as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.

If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.

ax = y - b

x = (y - b)/a

Thus, the linear equation can be written in the form of a, b, and y as x = (y - b)/a if the linear equation is y = ax + b.

I believe you mean that x needs to be isolated?

First, divide both sides by a. You'll get Y/A = x+b. Then, subtract b from both sides, to get Y/A - B = X.

Or x= y/a - b.

What is the product (2x-1)(x+4)

Answers

Answer:2x^2+7x-4.

Step-by-step explanation:

To find : The product of (2x-1)(x+4)

Using distributive property : a(b+c)=ab+ac , we have

(2x-1)(x+4)\n\n= (2x-1)x+(2x-1)4

Again , using distributive property : (b+c)a=ba+ca , we have

(2x-1)x+(2x-1)4=2x\cdot x+(-1)x+2x\cdot 4+(-1)4\n\n=2x^2-x+8x-4\n\n= 2x^2+7x-4

Hence, The product of (2x-1)(x+4) is 2x^2+7x-4.
2x(x+4)-1(x+4)
2x^2+8x-x-4
2x^2+7x-4

Can you please help find z?

Answers

Answer:

the angle for z° is 96°

Step-by-step explanation:

Since we already know 2 of the angles and that y=18° because both of the lines opposed to y are straight, so subtract all of what we know: 360-(64+18+18)=260°. x also has straight lines with the 64°, so subtract another 64°, then the equation will be 360°-(64+64+18+18), so z should equal 196, but there are 2 z angles, so divide it by 2 and the answer should be z°=96°
