Answer:

Step-by-step explanation:

First we need to figure out how many people are going on the field trip

if each class has 27 people going and there are 6 classes, 6*27=162

162 ppl are going. If 3 buses can hold 48 ppl then 3*48=144

3 buses are not enough, if we were to bring in one more bus 4*48=192

there would be enough place for everyone

Answer:

$y=1.25x+3.5$

Step-by-step explanation:

Let $y$ represent number of tickets and $x$ represent the total cost to purchase them.

Now,assuming the relation to be of the form:

$y=ax+b$ , where, $a$ and $b$ are constants.

Let us find $a$ and $b$ using the values from the table.

For, $x=7,y=12.25$ . So,

$12.25=7a+b\\or\ 7a+b=12.25------------1$

For, $x=10,y=16$ . So,

$16=10a+b\\or\ 10a+b=16------------2$

Subtract equation 1 from equation 2. This gives,

$10a+b-7a-b=16-12.25\\(10a-7a)+(b-b)=3.75\\3a=3.75\\a=\frac{3.75}{3}=1.25$

Now, plug in $a=1.25$ in equation 1 and solve for $b$

$7(1.25)+b=12.25\\8.75+b=12.25\\b=12.25-8.75=3.5$

Therefore, the relation between the number of tickets and total cost of purchase is given as:

$y=ax+b\\y=1.25x+3.5$

Workout the length of AB. Give your answers to 3 significant figures.

german

Answer:

AB ≈ 6.71

Step-by-step explanation:

Calculate the length using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = A (- 1, 6) and (x₂, y₂ ) = B (5, 3)

AB = $\sqrt{(5-(-1))^2+(3-6)^2}$

= $\sqrt{(5+1)^2+(-3)^2}$

= $\sqrt{6^2+9}$

= $\sqrt{36+9}$

= $\sqrt{45}$

≈ 6.71 ( to 3 significant figures )
