Answer:

9 cups of flour

Step-by-step explanation:

[tex]\frac{3}{1} =\frac{y}{3}[/tex]

3:1 = y:3

1 × y = 3 × 3

y = 9

9 cups of flour

Answer:

1 batch = 3cups

so, we need to find how many cups of flour we'll need for 3 batches if 1 batch equals 3 cups....

1 batch = 3 cups

X

3 batches = a

a= 3 batches x 3 cups

= 9 cups

Answer:

Which expression is equivalent to (6x3+3x2+8)+(2x2−9x+10)?

Step-by-step explanation:  

6x3+3x2+8)+(2x2−9x+10)?

The equivalent expression is 6x^3+5x^2-9x+18.

An expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Algebraic expressions include at least one variable and at least one operation.

For the given situation,

The expression is [tex](6x^3+3x^2+8)+(2x^2-9x+10)[/tex]

⇒ [tex]6x^{3}+3x^{2} +8 +2x^{2} -9x+10[/tex]

Rearrange the expression in decreasing order of polynomial,

⇒ [tex]6x^{3}+3x^{2}+2x^{2} -9x+8+10[/tex]

Now add the like terms,

⇒ [tex]6x^{3} +5x^{2} -9x+18[/tex]

Hence we can conclude that the equivalent expression is [tex]6x^{3} +5x^{2} -9x+18[/tex].

Answer: To find the circumference of a circle, use the formula, 2(3.14)(r) (r is the radius, and if it gives the diameter, divide the diameter by 2 [to get the radius]). To find the actual circumference of the circle, multiply 2 and 3.14, becoming 6.28. Then, multiply 6.28 by whatever the radius is. Hope you find this useful!

Note: I am going based on no given picture and measurements of the circle, the other person that answered is, also, correct, and you could multiply the first two numbers (and then multiply the other number by the answer you received) OR multiply the first number, being 2, by the radius (and multiply that answer by the number of 3.14). For an example, the radius=10 units. You could either do 2x10=20, then 20x3.14=62.8 units^2 or multiply 3.14x2=6.28 units, then multiply 6.28 by 10, which is 62.8 units^2.

Answer: 173.82cm^2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

According to the inscribed Angle Theorem, the size of an inscribed angle = ½(measure of the intercepted arc)

m<L = (7x + 9)° is an inscribed angle

m(KM) = 46° is its intercepted arc

Therefore:

7x + 9 = ½(46)

Multiply both sides by 2

2(7x + 9) = 46

14x + 18 = 46

14x + 18 - 18 = 46 - 18

14x = 28

14x/14 = 28/14

x = 2

Answer:

m = rise/run = 4/5.

Step-by-step explanation:

This line goes throught the "exact" grid intersections (-2, 0) and (3, 4).  As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise').  Thus, the slope of this line is m = rise/run = 4/5.
