Answer:
Area = 24 in²
Perimeter = 24in
Step-by-step explanation:
To find the area given the length of the 3 sides:
a= 8in
b= 6.4in + 3.6in= 10in
c= 6in
Add them together:
8in + 10in + 6in
= 24in²
To find the perimeter you do the same thing:
a= 8in
b= 10in
c= 6in
Add them together
=24in
DO <u>NOT</u> SQUARE THE ANSWER WHEN FINDING <u>PERIMETER</u>
Answer:
B
Step-by-step explanation:
Product refers to multiplication and B is the only one the uses multiplication with 8.
Slope=-4 or -4/1
Work:
(2, 5) (3, 1)
x1 y1. x2 y2
M= y2-y1/x2-x1
M= 1-5/3-2
M= -4/1
M=-4
Answer:
The frequency table is shown below
Step-by-step explanation:
(i) Half of the tuna sandwich were on white bread = 21
On brown bread, tuna = 42 - 21 = 21
(ii) 25% of the ham sandwiches sold were on brown bread.
= 25% (32) = 8
On white bread, 32 - 8 = 24
Frequency table:
Tuna Cheese Ham Total
Brown 21 11 8 40
White 21 15 24 60
Total 42 26 32 100
Answer:
first one is C
the second it is A
Step-by-step explanation:
the equation of a circle=(x-h)^2 + (y-k)^2 = r^2
h and k are the coordinate of the origin of a circle
to find the origin which is the midpoint of the diameter which has end points
(9,1) and (1,9)
h=9+1/2 = 10/2=5
k=9+1/2 = 10/2=5
(x-5)²+(x+5)²=r²
find r which is the half distance of the diameter
d of diameter : √(x2-x1)²+(y1-y2)²
d=√(9-1)²+(1-9)²
d=√8²+8²=8√2
radius=8√2/2=4√2
(x-5)²+(x+5)²=r²
(x-5)²+(x+5)²=(4√2)²
(x-5)²+(x+5)²=32
TR>TS the sides RS and TS are congruent opposite angles are equal.
