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

Find the circumference of a circle with radius, r = 16m. Give your answer in terms of π .
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.

Increase £101 by 16%
Give your answer rounded to 2 DP.
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

What are two numbers that have a product of - 40 and have a sum of 18?
Step-by-step explanation:
xy = -40 and x + y = 18
=> x(18 - x) = -40
=> 18x - x² = -40
=> x² - 18x - 40 = 0
=> (x - 20)(x + 2) = 0
=> x = 20 or x = -2.
The two numbers 20 and -2.
Answer:
let the numbers be x and y
[tex]xy = - 40 - - - (i) \\ x + y = 18 - - - (ii) \\ from \: (ii) \\ x = 18 - y \\ substitute \: for \: x \: in \: (i) \\ (18 - y)y = - 40 \\ 18y - {y}^{2} = - 40 \\ {y}^{2} - 18y - 40 = 0 \\ use \: the \: quadratic \: equation \: to \: get \: y \\ and \: y \: will \: give \: u \: x[/tex]
x = 20
hence y = 18-20
y = -2
or
x = -2
hence y = 18-(-2)
y = 20
The numbers are -2 and 20

Child admissions is 5.50 adult admission is 9.80 159 tickets where sold total sales 1136.80 how many where child admissions
Answer:
98
Step-by-step explanation:
Given that:
Total number of tickets sold = 159
Ticket price for child admissions = 5.50
Ticket price for adult admissions = 9.80
Total money spent = 1136.80
To find:
The number of child admissions.
Solution:
Let number of child admissions = [tex]x[/tex]
Let number of adult admissions = [tex]y[/tex]
As per question statement:
[tex]x+y = 159[/tex] ...... (1)
and
Money spent for child admissions = 5.50[tex]x[/tex]
Money spent for adult admissions = 9.80[tex]y[/tex]
[tex]5.50x+9.80y = 1136.80[/tex] ...... (2)
Using equation (1):
[tex]y = 159-x[/tex]
Putting in equation (2) from above:
[tex]5.50x+9.80(159-x) = 1136.80\\\Rightarrow 5.50x+1558.2-9.8x=1136.80\\\Rightarrow 4.3x = 421.4\\\Rightarrow x = \bold{98}[/tex]
Therefore, total number of child admissions is 98.
If y varies directly as x and y = 11 when x = 2.5, find y when x = 27.5.
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)

Given: SV || TU and SVX = UTX

Answer:
ΔSVX ≅ ΔUTX Given
SV // TU Given
SV ≅ TU Corresponding part of congruent triangle
VUTS parallelogram Definition of parallelogram.
Step-by-step explanation:
The given figure VUTS is a parallelogram.
What is Parallelogram?Parallelogram is a type of polygon with four sides, four angles and four vertices. It is a type of Quadrilateral.
Opposite sides are parallel, and the opposite sides and opposite angles are equal.
Given that,
SV ║TU
Also ΔSVX ≅ ΔUTX
Since both the triangles are congruent, corresponding sides are equal.
SV = UT
SX = UX
VX = TX
Consider two triangles ΔVUX and ΔSTX.
Already we have 2 corresponding sides of these triangles are equal from above.
So third side is also equal.
Since US is a transversal line that cuts the parallel lines VS and UT, ∠VUX = ∠TSX (alternate interior angles)
Similarly, VT is also a transversal line that cuts the parallel lines VS and UT,
∠UVX = ∠STX
So the two lines VU and ST are parallel.
Hence the figure is parallelogram since opposite sides are equal and parallel.

Kim drives 156 miles from rotherham to london she drives at an average speed of 60 miles per hour she leaves rotherham at 7:30 am does she arrive before 10:00 am?
Given :
Kim drives 156 miles from rother ham to London she drives at an average speed of 60 miles per hour she leaves rother ham at 7:30 am .
To Find :
Can she arrive before 10:00 am.
Solution :
Time taken to cover 156 miles with speed of 60 miles per hour.
[tex]t= \dfrac{Distance}{Time\ taken}\\\\t = \dfrac{156}{60}\ hour\\\\t = 2.6\ hours[/tex]
To arrive before 10:00 am she has only 2.5 left.

What is the value of a, if the graphs of 3y + x = 0 and 4y + ax + 3 = 0 are to meet at a right angle?
Answer:
a = -12
Step-by-step explanation:
For two lines to meet at a right angle, they are perpendicular to each other. Therefore the product of the slopes of the two lines is -1.
The slope of 3y + x = 0 will be -1/3 (rearrange the terms, 3y = -x and therefore y = -1/3 x).
The slope of 4y + ax + 3 = 0 will be -a/4. (4y = -ax - 3, therefore y = -a/4 x - 3/4)
Since the product of the slopes is -1, we can set up an equation now.
-1/3 * -a/4 = -1
a/12 = -1
a = -12
find a quadratic polynomial the sum and product of whose zeroes are -3 and 2 respectively
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]
