Answer:

Question 1: b) Find the total distance from A to B

Distance formula:

d=Square root of (x2-x1)^2+(y2-y1)^2+(z2-z1)^2

d=Square root of (6-4)^2+(12-8)^2+(10-2)^2

d= 9.165 = 9.17 units

Answer:

1 a

Use the midpoint formula:

m=x1+x2/2, y1+y2/2, z1+z2/2

m= 4+6/2 ,8+12/2, 2+10/2

m= (5 ,10, 6)

Answer:

8.4 kg

Step-by-step explanation:

First, find how much waste is created in a week:

Multiply 2 by 7, since they create 2 kg of waste each day:

2(7)

= 14 kg

Then, find 60% of this:

Multiply 14 by 0.6:

14(0.6)

= 8.4

So, the amount of compostable waste created by 1 person in a week is approximately 8.4 kg

The amount of compostable waste that could be generated by one individual in a week would be closest to 8.4kg.

Using this formula
Compostable waste amount=Kg of waste× Number of days in a week× Municipal solid waste percentage

Where:
Kg of waste=2kg

Number of days in a week=7 days

Municipal solid waste percentage=60% or 0.60

Let plug in the formula

Compostable waste amount=2kg×7 days×0.60

Compostable waste amount=8.4 kg

Inconclusion the amount of compostable waste that could be generated by one individual in a week would be closest to 8.4kg.

Answer:

19 floors

Step-by-step explanation:

Let us consider the ground floor as 0 and the floors above it as positive and the floors below the ground floor as negative.

So, the floor in which she parked is -4 and the floor where her office is at +15.

The number of floors she has to climb is the absolute value of the difference of the two floors.

The number of floors she has to go up is [tex]|-4-15|=19[/tex].

Answer:

At Irtaza's Deli

Step-by-step explanation:

For this you should find the unit price and whichever is less is where you should go.

(1) Irtaza Deli:

First I would round the 5.99 to 6 then we'll do 6 divided by 7.

[tex]\frac{6}{7}=.8571428571=.86[/tex]

(2) Brianna's Food Mart:

First I would round the 8.99 to 9 then we'll do 9 divided by 10.

[tex]\frac{9}{10}=.9[/tex]

Now let's compare:

So the first store sells oranges for $.86 and the second store sells them for $.90. I don't know about you but I would go to the first store they would be much more cheaper.

Dimensions:

Length = 13.256m

width = 9.256m

Step-by-step explanation:

Let the length of the sandbox be = l and its width be = w

The length of the sandbox is 4 ft more than the width.

This means that  [tex]l = 4 + w[/tex] ----- equation 1

For the next step, we will be assuming that the strip of grass is a perfect rectangle. The length of the grass strip will be equals to the length of the sandbox.

Area of the grass =  length X width = [tex](4 +w) \times 5= 5(4+w)[/tex]------ equation 2

The total area for the sandbox and the grass is 189 square feet.

This means that

[tex](w \times (4+w)) + 5(4+w)=189\\w^2+4w+20+5w=189\\w^2+9w-169=0\\w=9.256m[/tex]

(Kindly note that the positive value for the width was chosen as length cannot be negative).

Now that we have our width, we can put this into equation 1 to get the length.

[tex]l=9.256+4=13.256m[/tex]

Since they're not the same, they're not proportional.

Answer:

not proportional        

Step-by-step explanation:

First , let's find the speed of each person by dividing the distance traveled and the time.

Using B to represent Bob's speed and K to represent Kelly's speed , we have:

[tex]B=\frac{20}{4} = 5 mph\\K=\frac{14}{3}= 4.666 mph\\\\[/tex]

The speeds 5 and 4.666 are not multiples , so they are NOT proportional.

Answer:

6200 rupees

Step-by-step explanation:

Think the monthly income x

According to the question

The equation is

x×28%=1736

x×28/100=1736

x=1736÷28/100

x=1736×100/28

x=62×100

x=6200

So monthly income is 6200 rupees

Answer:

[tex]6200\ Rupees[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that,\\Percent\ of\ salary\ Marin\ spends\ for\ her\ loans=28 \% \\Amount\ of\ total\ payment\ on\ the\ loans= 1736\ rupees\\Hence,\\Let\ her\ monthly\ income\ be\ x\\Hence,\\The\ question\ also\ tells\ us\ that:\\28 \%\ of\ Marin's\ Monthly\ Income= Loan\ Payment\\Or,\\28 \%\ of\ x=1736\\Hence\ as\ 28 \%\ can\ also\ be\ represented\ as: \frac{28}{100},\\\frac{28}{100}*x=1736\\Hence\ by\ multiplying\ the\ LHS\ and\ RHS\ with\ \frac{100}{28},\\[/tex]

Answer:

m<R = 65

Step-by-step explanation:

m<R + m<S + m<T = 180° (sum of interior angles in a triangle)

(5x - 11) + (3x - 3) + (3x + 18) = 180°

Solve for x.

5x - 11 + 3x - 3 + 3x + 18 = 180

Add like terms

11x + 4 = 180

11x = 180 - 4

11x = 176

x = 16

m<R = (5x - 11)

Plug in the value of x

m<R = 5(13) - 11

m<R = 65

Answer:

30° ; 80°

Step-by-step explanation:

Given that :

One angle of a certain triangle = 70°

The other two angles are in the ratio 3 : 8

Recall :

Sum of angles in a triangle = 180°

Number of angles in a triangle = 3

Hence,

Sum of the other two angles + 70 = 180

Hence, sum of the other two angles = (180 - 70)°

Sum of other two angles = 110°

The angle is in the ratio 3:8

Hence,

(3 / (3 +8)) * 110

= 3/11 * 110

= 330 / 11

= 30°

(8 / (3 +8)) * 110

= 8/11 * 110

= 880 / 11

= 80°

Hence ; 30° ; 80°
