Answer:

[tex]First \: you \: find \: the \: gradient \: of \: the \\ \: line \: using \: the \: formula[/tex]

[tex] \frac{ {y}{2} - y1}{x2 - x1} [/tex]

[tex] \frac{ 4 - 2}{ - 1 - - 4} = \frac{2}{3} = 0.66666666666[/tex]

[tex]Next, use \: the \: equation \: of \: a \: line \: \\ which \: is[/tex]

[tex](y - y1) = m(x - x1)where \: m \: is \: the \: gradient.[/tex]

[tex](y - 4) = 0.66666666666(x - - 1)[/tex]

[tex] = y - 4 = x + 0.66666666666[/tex]

[tex]Therefore,[/tex]

Answer:

1658.3

Step-by-step explanation:

the perimeter of a semi - circle is simply half the circumference of a circle.

that is ;

1 / 2 ( pi ( r² ) )

where;

pi = 3.14 ( this is a constant that should be known and also equals 22 / 7 )

r = radius ( or half a diameter )

in our question, we are given a diameter with no radius

this means that we will have to halve the diameter to give us our radius

that is;

d = 65cm

r = 65 / 2

r = 32.5

so, using our formula;

1 / 2 ( 3.14 ( 32.5² ) )

1 / 2 ( 3.14 ( 1056.26 ) )

1 / 2 ( 3316.65 )

1658.3125

rounded to 1 DP;

1658.3

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A gift shop sells souvenir magnets. The store is selling 3 magnets for $10. At this price. The cost to buy 8 magnets will be

Let x be the cost of 8 magnets.

We know that the ratio of the cost and the number of magnets will be constant. Then we have

x / 8 = 10 / 3

x = $26.67

At this price. The cost to buy 8 magnets will be $26.67.

Step-by-step explanation:

formula for volume of cone is 1/3πr^2h

The answer is 22 orange marbles. Let me explain. Since 60% are orange and 10% are red, the rest, 30% is yellow. So we learn that every 10% equals to 2 marbles. If you add 60% + 50% = 110%

90% = 18

And we have to add 4 more because 10%×2.

So the total comes to 18+4= 22.

Equation:

X+Y=203

X=70

Answer:

x - y = 70 and x + y = 203 are the required system of equations represents this situation.

Step-by-step explanation:

Given that factory has 203 workers  

Let "x" represent the number of males and let "y" represent the number of females  

There are 70 more males than females. Which means,  

Number of males = 70 + number of females  

x = 70 + y  

On rearranging we get,  

x - y = 70 ----> equation 1  

It is given that factory has 203 workers, which means number of males and females is equal to 203  

Number of males + number of females = total workers  

x + y = 70 ---- equation 2  

So equation 1 and equation 2 represents the system of equations for this situation

x - y = 70 and x + y = 203 are the required system of equations

Answer:

100cm

Step-by-step explanation:

The relationship between the ratio and the heights is 20. i.e 4 : 5 = 80 : 100

Hope this helps, please tag brainliest.

The height of the taller boy is 100cm.

Ratio, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.

Let the height of the taller boy be x cm and smaller boy be y cm.

According to the given question.

The ratio of height of the two boys is 4:5.

Since, it is obvious that 4:5 is the ratio of the height of smaller boy to the taller boy. Because k will be the ratio of proportionality then 4k will given the smaller value and 5k will give the larger value therefore, 4:5 represents the ratio of height of smaller boy to the taller boy.

[tex]\implies \frac{y}{x} =\frac{4}{5}[/tex]

Also, the height of the shorter boy is 80cm.

Therefore,

[tex]\frac{80}{x} = \frac{4}{5}[/tex]

[tex]\implies 80\times 5 = 4\times x[/tex]

[tex]\implies 400 = 4\times x[/tex]

[tex]\implies x = \frac{400}{4}[/tex]

[tex]\implies x = 100cm[/tex]

Hence, the height of the taller boy is 100cm.
