Mrs . Kerr is going to pack 9 carrots, 12 crackers, and 18 grapes into lunch boxes. How many of each food item will be in a lunc

Lilit [14]

Answer:

3 carrots, 4 crackers, and 6 grapes.

Step-by-step explanation:

The greatest common factor of 9, 12, and 18 is 3, so we know that we can make at most 3 identical lunchboxes. Now we have to divide each number by 3 to figure out how much of each item is in each lunchbox. 9/3=3, 12/3=4, and 18/3=6 so there will be 3 carrots, 4 crackers, and 6 grapes in each lunchbox.

Answer:

$x=4\sqrt{2}\ units$

Step-by-step explanation:

Theorem: In the right triangle the leg is the geometric mean of the hypotenuse and the segment of the hypotenuse adjacent to the leg.

Based on the theorem above,

$x^2=2\cdot (2+6)\\ \\x^2=4\cdot 8\\ \\x^2=32\\ \\x=\sqrt{32}\ units\\ \\x=4\sqrt{2}\ units$

What is the solution to<br> 6(2 - x)<-4x + 2?

cupoosta [38]

Answer:

Solving $6(2 - x)$ we get $\mathbf{x>5}$

Step-by-step explanation:

We need to find solution of $6(2 - x)$

Solving the inequality:

$6(2 - x)$

Multiply 6 with terms inside the bracket

$12-6x$

Subtracting 12 on both sides

$12-6x-12$

Adding 4x on both sides

$-6x+4x$

Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >

$\frac{-2x}{-2}>\frac{-10}{-2}\\\mathbf{x>5}$

So, after solving $6(2 - x)$ we get $\mathbf{x>5}$

Find the area of the triangle with A =42 degrees, b = 8 feet, and c = 5 feet. Round to the nearest tenth.

emmasim [6.3K]

We will use the formula:
Area = 1/2*a*c*sinB

where a and c are the length of the sides and B is the angle between those 2 sides

Area = 1/2*5*8*sin42
Area = 20*sin42
sin 42 = <span>0.669130606359
Area = </span>13.38261212718

Rounded to the nearest tenth Area is equal to 13.4
