What is the GCF of 24 and 44?

mariarad [96]

<span> write out all the factors of each number or draw out a factor tree

24:1,2,3,4,6,8,12,24

44:1,2,4,11,22

the GCF is the largest number in both the lists so in this case it is 4 </span>

10. from the question; the circle theorem obeyed is "angled formed by semi-circle"

The angle formed in a semicircle is 90 degrees, hence

$m\angle XYZ=90^{\circ}$

This gives

$m\angle YXZ\text{ + m}\angle YZX\text{ = 90}$

But

$\begin{gathered} m\angle YXZ\text{ = 2x + 8} \\ m\angle YZX\text{ = 5X - 2} \end{gathered}$

Substituting values we get

$\begin{gathered} 2x\text{ + 8 + 5x - 2 = 90} \\ 2x\text{ + 5x + 8 - 2 = 90} \\ 7x\text{ + 6 = 90} \\ 7x\text{ = 90 -6} \\ 7x\text{ = 84} \\ \text{divide both sides by 7} \\ x\text{ = }\frac{84}{7} \\ x\text{ = 12} \end{gathered}$

hence, x =12

The frame around a picture with an area of 192 square inches, measures x inches across. The length of the picture with its frame

prisoha [69]

Okay so
area of picture= 192cm
area of frame= 40×24=960

960÷ 192= 5

Therefore the picture is 1/5 of the frame.
Length of picture = 1/5 × 40 = 8cm
Width of picture = 192/8 = 24

The dimensions of the picture are then 8cm × 24 cm.

3. a) p∝1/m
P=k/m
48=k/9
48×9=k
k=432

the equation is: p=432/m

b) p∝1/m
P=k/m
P=432/12
P=36

The attachment below is the question

kotykmax [81]

I would say about 189 people. I found the percentage of 8 out of 11, which I rounded to the nearest tenth and got 73%. Since that is how much do carry brief cases, I took 100-73 and got 23% for those who don’t carry briefcases. Then I found 23% of 700, which is 189. So, 189 out of 700 people do not carry briefcases.
