What's 4a + 24 got to factorise fully

Six groups of students sell 162 balloons at the school carnival there are 3 students in each group if each student sells the sam

Kitty [74]

Each student sells 9 balloons because 162 balloons divided by 6 groups of students is 27, and 27 divided by 3 students is 9 balloons.

Blake and two friends equally shared the cups of water shown in the picture.

3241004551 [841]

The answer would be c- 2/6

there are six cups total and three (blake plus two others) friends

there are two ways you can solve this…

1. by making groups
if you look at the picture, you can split it into three groups because that is the number of people, then count how many cups there are in one group which will be your numerator for the denominator six which is the total

2. simple division
divide the total number of cups buy the number of people which is 3
you get two and follow the same process above

Given ΔABC with A(–4, –2), B(4, 4), and C(18, –8), write the equation for the line containing median segment The term is line se

Monica [59]

Here we want to find the equation of the line containing the median CP.

P, being the midpoint of AB can be found using the midpoint formula as:

$\displaystyle{ P=( \frac{-4+4}{2} , \frac{-2+4}{2} )=(0, 1)$ .

The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

$\displaystyle{ m= \frac{y_2-y_1}{x_2-x_1}= \frac{-8-1}{18-0}= \frac{-9}{18}= \frac{-1}{2}$ .

Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

$y-1= \frac{-1}{2}(x-0)\\\\y= -\frac{1}{2}x+1$ .

Answer: $y=-\frac{1}{2}x+1$

Lucy watched TV for 25 of an hour on Monday. She watched 79 of an hour on Tuesday. What day did she spend more time watching TV?

notka56 [123]

Hello there,

Lucy watched more TV on Tuesday.

This is because 1 hour = 60 minutes.

so, 25% of 60 min = 15 min on Monday

and, 79% of 60 min = 47.7 min rounded gives 48 minutes on Tuesday...

Hope this answer helps. Good luck.

Which equation represents the line of BEST fit for the data?

Sladkaya [172]

Equation that fits best in data is $y = -30x + 4$ .Although there are no options , kindly match this equation to options available!

<u>Step-by-step explanation:</u>

We are given a graph with y & x-axis , with 4 points given and best fit for data can be found out by joining points . On joining points , we see that best fit is a line . General equation of a line is : $y = mx + c$ ,

where m = slope of line & c = intercept.

Let's calculate slope m :

Consider any two given points , let's have ( 4,0) & (3,30) :

Slope = m

⇒ m = $\frac{y_2-y_1}{x_2-x_1}$

⇒ m = $\frac{0-30}{4-3}$

⇒ m = $-30$

So , equation now becomes : $y = mx + c$

⇒ $y = -30x + c$

at x = 0 we have y = 4

$y = -30x + c$

$4 = -30(0) + c$

$c = 4$

Therefore, equation that fits best in data is $y = -30x + 4$ .Although there are no options , kindly match this equation to options available!
