Find the areas of these parallelograms, drawn on a centimetre grid.
b)
a)
Answer:
a-16cm
b-12cm if not iwill look again
Step-by-step explanation:
Area of the parallelograms are :(a) = 16 cm² and (b) = 12 cm² which is drawn on a centimeter grid.
What is Parallelogram?A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal. A parallelogram is a square and a rhombus is a square.
The formula to calculate the area of a parallelogram can thus be given as,
Area of parallelogram = b × h square units
where b is the length of the base and h is the height or altitude
For parallelogram (a),
length of the base = 4 cm
the height or altitude = 4 cm
Area of parallelogram (a) = b × h = 4 × 4
Area of parallelogram (a) = 16 cm²
For parallelogram (b),
length of the base = 2 cm
the height or altitude = 6 cm
Area of parallelogram (b) = b × h = 2 × 6
Area of parallelogram (b) = 12 cm²

You are taking a trip at the same time as another
family. Your family traveled 1.900 miles in 2 days,
their family traveled 2.700 miles in 3 days. Who is
traveling fastera
Answer:
My family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.
Step-by-step explanation:
Since I am taking a trip at the same time as another family, and my family traveled 1,900 miles in 2 days, while their family traveled 2,700 miles in 3 days, to determine who is traveling faster the following calculation must be performed:
1,900 / 2 = 950
2,700 / 3 = 900
Thus, my family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.

Evaluate using the functions f(x) = 3x–8 and g(x) = -x2+ 4x–11.
1 . f(10+10
2. g(-9)+7
3. -2xg(4)
4. f(-4)-g(7)
5. Given f(x)= 9 –2x, if f(x)= 19, find the value of x.
The value of f(10)+10 for the given function is 32.
The given functions are f(x) = 3x-8 and g(x) = -x²+ 4x-11.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
1) Put x=10 in the function f(x) = 3x-8, we get
f(10)=3(10)-8
= 22
So, f(10)+10
= 22+10=32
2) Put x=-9 in the function g(x) = -x²+ 4x-11, we get
g(-9)=-(-9)²+4(-9)-11
= -81-36-11
= -128
So, g(-9)+7
= -128+7
= -121
3) Put x=4 in the function g(x) = -x²+ 4x-11, we get
g(4) = -(4)²+4(4)-11
=-16+16-11
=-11
Now, -2xg(4) =-2x(-11)
=22x
4) Put x=-4 in the function f(x) = 3x-8, we get
(-4)=3(-4)-8
= -20
Put x=7 in the function g(x) = -x²+ 4x-11, we get
g(7)=-(7)²+4(7)-11
= -49+28-11
= -32
5. Given f(x)= 9 –2x, if f(x)= 19
Now, 9-2x=19
⇒ -2x=10
⇒ x=-5
Therefore, the value of f(10)+10 for the given function is 32.

Answer:
(x, y) = (3, 7)
Step-by-step explanation:
If you divide the second equation by 2, it becomes ...
-x +2y = 11
Adding this to the first equation gives you the value of y:
(x -y) +(-x +2y) = (-4) +(11)
y = 7 . . . . . . . . simplify
The first equation can be rearranged to give an expression for x:
x = y -4
x = 7 -4 = 3
Then the solution is seen to be (x, y) = (3, 7).

Amelia was showing off her basketball skills. She scored a total of 14 shots for a total of 32 points. How many 2 point and 3 point shots did she make?
Answer:
Step-by-step explanation:
x+y=14
y=14-x
2x+3y=32, using y=14-x we have
2x+3(14-x)=32
2x+42-3x=32
-x+42=32
-x=-10
x=10, and since y=14-x
y=14-10=4
So Amelia made 10 two-pointers and 4 three-pointers.
1. HEIGHT Eduardo is 6 feet tall and casts
a 12-foot shadow. At the same time,
Diane casts an 11-foot shadow. Ilow tall
is Diane?
Answer:
5.5
Step-by-step explanation:
6 feet =12
6 feet = 6x2
11 feet shadow 11/2
answer=5.5
The height of the diane when the height of euardo and diane cast should be given so it should be 5.5.
Calculation of the height:Since
HEIGHT Eduardo is 6 feet tall and casts a 12-foot shadow. At the same time, Diane casts an 11-foot shadow.
So,
6 feet tall = 12
Now for 11 foot it should be half like 5.5

We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
ΔABD is similar to ΔBCD.
This means,
The corresponding sides ratio is equal.
AB/BC = BD/CD = AD/BD
AB/m = BD/7 = 11/BD
Now,
BD/7 = 11/BD
BD² = 77
BD = √77
Now,
ΔBDC
BC² = CD² + BD²
m² = 7² + 77
m² = 49 + 77
m² = 126
m = √126
Thus,
The value of m in the figure is √126.
