Answer:
Perimeter = 126cm
Area = 972cm^2
Step-by-step explanation:
6*4.5 = 27
8*4.5 = 36
Perimeter = 27*2+36*2= 126 cm
Area = 27*36 = 972 cm^2
Hope this helped!
Answer:
Perimeter = 126 cm, area = 972 cm2
Step-by-step explanation:
Rectangle perimeter:
P = 2(w + l)Rectangle area:
A = wlWhen scaled, the perimeter will change by same factor but the area by the square of same factor.
Applying to the given rectangle
Perimeter:
P = 2(6 + 8)(4.5) = 126 cmArea:
A = 6*8*4.5² = 972 cm²Correct choice is B

Answer:
42
Step-by-step explanation:
3/(3+x-6)=5/(5+x)
cross multiply
3(5+x)=5(3+x-6)
15+3x=15+5x-30
15+3x=5x-15
15+15=5x-3x
30=2x
x=15
That means KQ=15 and PK=15-6=9. Now we have to find PQ, which is the same as JM. We’ll call that length b.
5/15=6/b
cross multiply
5b=90
b=18

. In a group of 37 people waiting in line at the local java house, 18 wanted to order a cappuccino, 20 wanted to
order a latte, and 2 wanted neither of these drinks. How many wanted to order both a cappuccino and a latte?
Answer:
36
Step-by-step explanation:
Its 36 because normally someone would do 18+20=38 but you have to remeber in the problem it says 37! so 2 people didn't want anything, minus that and you get 36.

Answer:
0.5+8
Step-by-step explanation:
The slope intercept form is mx+b
Mx is the slope
b is the y intercept
The slope formula is y2-y1/x2-x1
2 points to find the slope:
(2,9) (4,10)
10-9=1
4-2=2
1/2=0.5
The y-intercept is the number that goes through the number line when x equals 0. The y intercept is 8.
What is the ratio in which the point P(3/4,5/12) decides the line segment joining points A(1/2,3/2) and B(2,-5)
Given:
The point [tex]P\left(\dfrac{3}{4},\dfrac{5}{12}\right)[/tex] divides the line segment joining points [tex]A\left(\dfrac{1}{2},\dfrac{3}{2}\right)[/tex] and [tex]B(2,-5)[/tex].
To find:
The ratio in which he point P divides the segment AB.
Solution:
Section formula: If a point divides a segment in m:n, then the coordinates of that point are,
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Let point P divides the segment AB in m:n. Then by using the section formula, we get
[tex]\left(\dfrac{3}{4},\dfrac{5}{12}\right)=\left(\dfrac{m(2)+n(\dfrac{1}{2})}{m+n},\dfrac{m(-5)+n(\dfrac{3}{2})}{m+n}\right)[/tex]
[tex]\left(\dfrac{3}{4},\dfrac{5}{12}\right)=\left(\dfrac{2m+\dfrac{n}{2}}{m+n},\dfrac{-5m+\dfrac{3n}{2}}{m+n}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{3}{4}=\dfrac{2m+\dfrac{n}{2}}{m+n}[/tex]
[tex]\dfrac{3}{4}(m+n)=\dfrac{4m+n}{2}[/tex]
Multiply both sides by 4.
[tex]3(m+n)=2(4m+n)[/tex]
[tex]3m+3n=8m+2n[/tex]
[tex]3n-2n=8m-3m[/tex]
[tex]n=5m[/tex]
It can be written as
[tex]\dfrac{1}{5}=\dfrac{m}{n}[/tex]
[tex]1:5=m:n[/tex]
Therefore, the point P divides the line segment AB in 1:5.

Use the triangle below to find cos V.
Answer:
[tex]cos\ V = \frac{2\sqrt{29}}{29}[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find cos V
In trigonometry:
[tex]cos\theta = \frac{Adjacent}{Hypotenuse}[/tex]
In this case:
[tex]cos V= \frac{TV}{UV}[/tex]
Where
[tex]TV = 6[/tex]
and
[tex]UV^2 = TV^2 + TU^2[/tex] -- Pythagoras
[tex]UV^2 = 6^2 + 15^2[/tex]
[tex]UV^2 = 261[/tex]
Take square roots
[tex]UV = \sqrt{261[/tex]
[tex]UV = \sqrt{9*29[/tex]
[tex]UV = \sqrt{9} *\sqrt{29[/tex]
[tex]UV = 3\sqrt{29[/tex]
So:
[tex]cos V= \frac{TV}{UV}[/tex]
[tex]cos\ V = \frac{6}{3\sqrt{29}}[/tex]
[tex]cos\ V = \frac{2}{\sqrt{29}}[/tex]
Rationalize:
[tex]cos\ V = \frac{2}{\sqrt{29}}*\frac{\sqrt{29}}{\sqrt{29}}[/tex]
[tex]cos\ V = \frac{2\sqrt{29}}{29}[/tex]
