Answer:
3.69 mm
Step-by-step explanation:
So it's a right triangle so you can use a^2+b^2=c^2
Plugging in what we know the equation becomes:
2.8^2+2.4^2=c^2 (C = x because x is the hypotenuse)
7.84+5.76=c^2
13.6=c^2
The square root of 3.68782 which rounds to 3.69
So x=3.69mm

Increase £101 by 16%
Give your answer rounded to 2 DP.
Answers
If we increase £101 by 16% then it would be £117.16
What is percent?"It is the number that can be expressed as a fraction of 100."
For given example,
we need to increase £101 by 16%
First we find the 16 percent of £101
16% of £101 = 101 × (16/100)
16% of £101 = 101 × 0.16
16% of £101 = £16.16
So, if we increase £101 by 16% then it would be,
£101 + £16.16 = £117.16
Therefore, if we increase £101 by 16% then it would be £117.16

Answer:
27.5
Step-by-step explanation:
y=consx
y=x
y=27.5
Answer:
121
Step-by-step explanation:
you can either set up a proportion or a table (i inserted a picture for both ways!) After setting up a table you would calculate how much it is to get from 2.5 to 27.5 (so you divide 27.5/2.5) to get 11. Then you move to the y side of the table where you would have to multiply 11×11 to get your answer (which is 121)

Find the circumference of a circle with radius, r = 16m. Give your answer in terms of π .
Answers
Answer:
[tex]32\pi[/tex] meters
Step-by-step explanation:
The formula for finding the circumference of a circle is [tex]C=2\pi r[/tex], where [tex]C[/tex] = circumference and [tex]r[/tex] = radius. In this case, we are solving for [tex]C[/tex] and we know that [tex]r=16[/tex], so after substituting [tex]r=16[/tex] into [tex]C=2\pi r[/tex], we get:
[tex]C=2\pi r[/tex]
[tex]C=2\pi *16[/tex] (Substitute [tex]r=16[/tex] into [tex]C=2\pi r[/tex])
[tex]C=32\pi[/tex] (Simplify RHS)
Hope this helps!
We have,
Radius of the circle = 16 m
We know,
Circumference = 2πr
∴ Circumference = 2π × 16 m = (32π) m.

Answer:
base area: 21 ft²volume 105 ft³Step-by-step explanation:
The area of a triangle is given by the formula ...
A = (1/2)bh
The base and height of a right triangle can be taken to be the leg lengths, since each is perpendicular to the other.
A = (1/2)(6 ft)(7 ft) = 21 ft² . . . . base area
__
The volume is the product of the base area and the height:
V = Bh
V = (21 ft²)(5 ft) = 105 ft³ . . . . volume
Nathan and Olivia are saving money for school supplies. Nathan saves $2 per week and already has $30 in his bank. Olivia saves $4 per week and has $15 in her bank. Write the system of equations for this situation.
Answers
Answer:
Nathan: 2x+30
Olivia: 4x+15
Step-by-step explanation:
x is the number of weeks
Nathans account is as follows
2x+30
(2 dollars a week plus the 30 dollars already there)
Olivia's account is as follows
4x+15
(4 dollars per week plus the 15 already in there)
The system of equation for the given situation should be considered
Nathan: 2x+30
Olivia: 4x+15
Calculation of the system of equation:here we assume x is the number of weeks
So for nathan, the equation is 2x+30
And, for Olivia's account is 4x+15

find a quadratic polynomial the sum and product of whose zeroes are -3 and 2 respectively
Answers
Answer:
[tex]P(x)=x^2+x-6[/tex]
Step-by-step explanation:
Quadratic Polynomial
Assume we have a polynomial factored as:
P(x)=a(x-m)(x-n)
Where m and n are the zeros of P(x).
Operating:
[tex]P(x)=a(x^2-(m+n)x+mn)[/tex]
Note the coefficient of x is the negative sum of the zeros and the independent term is the product of the zeros.
If we are given the zeros m=-3 and n=2, then:
[tex]P(x)=a(x^2-(-3+2)x+(-3)(2))[/tex]
[tex]P(x)=a(x^2+x-6)[/tex]
We can choose any value for a, for example, a=2:
[tex]P(x)=2x^2+2x-12[/tex]
For a=1:
[tex]P(x)=x^2+x-6[/tex]

The lines (m-2)x+y=2 and mx+2y=k intersect at (2,8). Find the values of m and k
Answers
Answer:
m = - 1, k = 14
Step-by-step explanation:
The coordinates of the point of intersection (2, 8 ) satisfy both equations.
Substitute x = 2, y = 8 into the equations and solve for m and k
(m - 2)x + y = 2
2(m - 2) + 8 = 2
2m - 4 + 8 = 2
2m + 4 = 2 ( subtract 4 from both sides )
2m = - 2 ( divide both sides by 2 )
m = - 1
and
mx + 2y = k
- 1(2) + 2(8) = k
- 2 + 16 = k
14 = k
Then m = - 1 and k = 14

what's the value of x?
Answers
Answer:
75
if your teacher says
that it is wrong then tell him/her to study once again
Answer:
x = 75
Step-by-step explanation:
The angle vertically opposite 50° is also 50° ( congruent )
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180° for x
x = 180° - (50 + 55)° = 180° - 105° = 75°
