Solve for x.<br> 3:12 = x:16<br> 2 1/4 <br> 4 <br> 64

borishaifa [10]

Hi!

We can set up a proportion to solve this

$\frac{3}{12} \frac{x}{16}$

Cross multiply

3 x 16 = 48
48/12 = 4

The answer is 4

Hope this helps! :)

An art shop has 80 large boxes of markers and 34 small boxes of markers in stock. Each large box contains 48 markers and each sm

Pavel [41]

Answer: n= 80 ×48+ 34×20

Step-by-step explanation:

Given: Number of large boxes = 80

Number of small boxes = 34

Number of markers in each large box = 48

Number of markers in each small box = 20

Total markers = (Number of large boxes)x (Number of markers in each large box) + (Number of small boxes) x (Number of markers in each small box)

Total number of markers = n (given)

Then, n= 80 ×48+ 34×20

Therefore , the equation could be used to find n, the total number of markers in stock: n= 80 ×48+ 34×20

What's the area of the room in this diagram?

GenaCL600 [577]

I believe it should be B.156 square feet because in order to find the area of a square, you gotta multiply 13ft and 12ft. Once that is solved your answer should be 156.

The coordinates of the vertices of A DEF are D(-4,1), E(3. – 1), and F(-1, – 4)

liq [111]

Answer:

ΔDEF is not a right triangle because no two sides are perpendicular.

Step-by-step explanation:

The coordinates of the vertices of ΔDEF are given to be D(-4,1), E(3,-1) and F(-1,-4).

Now length of DE is given by $\sqrt{(-4-3)^{2}+(1-(-1))^{2} } =\sqrt{53}$ units

length of EF is given by $\sqrt{(3-(-1))^{2}+(-1-(-4))^{2} }=\sqrt{25}$ units

and length of FD is given by $\sqrt{(-4-(-1))^{2}+(1-(-4))^{2} } =\sqrt{34}$ units.

Therefore, 53 ≠ 25+34

Hence, the length of the sides does not support the Pythagoras theorem.

So, ΔDEF is not a right triangle because no two sides are perpendicular. (Answer)
