Answer:
Step-by-step explanation:
4 - 0.4 = 3.6
3.6 - 0.4 = 3.2
2.8 - 0.4 = 2.4
2.4 - 0.4 = 2
2 - 0.4 = 1.6
so the next numbers in the pattern are: 2.4, 2 and 1.6
If f(x) = √ x + 3, then f' (1) =
Answer:
4
Step-by-step explanation:
Do you see f(x) (f of x)? if the (x) part is a number, plug that number in as x on the other side of the equal sign. If I plug 1 in, I get 4, because the square root of 1 is 1, and 1+3=4.

Find the perimeter of this semi-circle with diameter, d = 65cm. Give your answer rounded to 1 DP.
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;

(Level 4) In a bag of orange, red, and yellow, 60% are orange, and 10% are red. There
are 6 yellow marbles in the bag. If you increase the number of orange marbles by 50%,
how many orange marbles are in the bag?
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.

The height of two boys are in the ratio of 4:5 the shorter boy is 80 cm what is the height of the taller boy?
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.
What is ratio?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.
