Answer:

8700kg

Step-by-step explanation:

lorry + bricks = 11600kg

bricks = 3(mass of empty lorry)

lorry mass is x

there for bricks = 3x

x+3x = 11600

4x =11600

x= 2900kg

mass of bricks = 3(2900)

=8700kg

Answer:

x

Step-by-step explanation:

Answer:

36 ft

Step-by-step explanation:

6/x=7.5/45

270=7.5x

x=36

In this exercise we have to have knowledge of triangles, so we can use the theory of similar triangles to find the value of X, like:

[tex]36 ft[/tex]

To use similar triangle theory, we have to make a rule of 3, that is:

[tex]6/x=7.5/45\\270=7.5x\\x=36[/tex]

The correct statement is  BC equals to AC times CE all over CD.

We have, If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. this is known as the triangle proportionality theorem.

Given, DE and AB are parallel

So,   [tex]\frac{BC}{CE} =\frac{AC}{CD}[/tex]

[tex]BC = \frac{AC\times CE}{CD}[/tex]

Therefore in statement form we say that BC equals to AC times CE all over CD.

Answer:

0

Step-by-step explanation:

Answer:

The range is [0,37.5]

Step-by-step explanation:

We start by writing the equation that links x and y

From the question;

y = 7.5x

Now, she has enough material to make 5 only

When we talk of range, we are referring to the values on the y-axis

So the lowest y value is 0

and since the highest number of bracelets is 5;

The total cost of the 5 is 7.5(5) = 37.5

So the range is [0,37.5]

Answer:

5y = 4x-25

Step-by-step explanation:

Let f(x) be regarded as y

So we have two points

(5,-1) and (0,-5)

We start by finding the slope of the line connecting the two points

m = y2-y1/x2-x1

m = -5+1/0-5 = -4/-5 = 4/5

The general equation of a straight line is;

y = mx + b

where m

is slope and b is the y-intercept

we already have the slope as 4/5

So;

y = 4x/5 + b

To get b, substitute one of the points

Let us use (0,-5)

-5 = 4(0)/5 + b

so b = -5

The equation is;

y = 4x/5 - 5

Multiply through by 5

5y = 4x - 25

Answer:Hello! Here we have a cube, with a mass of 10g and a side length of 2.5cm.

First we want to determine the volume.

The volume of a cube, is equal to his cubic side length, where  L is the side length:

So  

So the volume of the cube is 15.625 cubic centimeters.

Now we want to calculate te density of the material, as you know:

This means that the density is 0.64 grams per cubic centimeter.

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

1. Determine the value: V=L^3

so, (1.7)^3= 4.913

2. Calculate the density: mass divided by volume

10 divided by 4.913= 2.0

I don't know if I'm correct but the answer is 6.

Step-by-step explanation:

I'm not 100% correct, but you set the other two angles to add to each other then set it equal to angle QRS and i got x=6.

Your equation should be like this: 3x + 17 + 2x +21 = 10x -1

than you solve form there

I;m not sure that this is the correct answer and maybe i'm wrong, but hope this helps

Answer:

59°

Step-by-step explanation:

According to the given description, [tex] \angle QRS[/tex] is the exterior angle of [tex] \triangle PQR[/tex]

So, by exterior angle property of a triangle, we have:

[tex] m\angle QRS=m\angle RPQ+m\angle PQR\\\\

(10x - 1)\degree = (3x +17)\degree+(2x +12)\degree\\\\

(10x - 1)\degree = (3x +17+2x +12)\degree\\\\

(10x - 1)\degree = (5x +29)\degree\\\\

(10x - 1)= (5x +29)\\\\

10x - 5x = 29 + 1\\\\

5x = 30\\\\

x = \frac{30}{5}\\\\

x = 6\\\\

\because m\angle QRS = (10x - 1)\degree \\\\

\therefore m\angle QRS = (10\times 6- 1)\degree \\\\

\therefore m\angle QRS = (60- 1)\degree \\\\

Answer:

2067 voters

Step-by-step explanation:

Suppose that three out of five voters support a candidate.

This means 3/5 votes support a candidate

Let the total number rod candidates be represented as x

If 1,240 voters support the candidate,

how many voters participated in the election in all?

Hence,

3/5 of x = 1240 voters.

3/5 × x = 1240

3x /5 = 1240

Cross Multiply

3x = 1240 × 5

x = 1240 × 5/3

x = 2066.6666667 voters

Approximately to the nearest whole number:

2067 voters

Answer:

The cashier is wrong

[tex]Amount = 64.99[/tex]

Step-by-step explanation:

Given

[tex]Jeans=34.95[/tex]

[tex]Shirt = 24.95[/tex]

[tex]Sales\ Tax = 8.5\%[/tex]

Solving (a): Is the Cashier's step correct?

The cashier is wrong at step 2 because instead of calculating the sales tax, the cashier add the sales tax percentage to the total cost.

Solving (b):

First, calculate the total cost by adding the cost of jeans and shirt respectively:

[tex]Total = 34.95 + 24.95[/tex]

[tex]Total = 59.90[/tex]

Next, multiply the sales tax percentage to the total cost to get the sales tax amount.

[tex]Sales\ Tax = 8.50\% * 59.90[/tex]

[tex]Sales\ Tax = 5.0915[/tex]

Add the sales tax to the total, this gives the total payable amount.

[tex]Amount = 59.90 + 5.0915[/tex]

[tex]Amount = 64.9915[/tex]

[tex]Amount = 64.99[/tex] approximated
