How do you find the height of a parallelogram without the area of it?
Answer:
See: https://brainly.in/question/12682555
Step-by-step explanation:
The link provided will take you to a differently worded explanation from another user.
You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:
c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.
Someone please help me asap! I need serious answers and please explain!!! Brainliest
Hey there!
The answer is "[tex]12 * 16 = 20^2[/tex], therefore the triangle is a [tex]right[/tex] [tex]triangle[/tex]"
This is known as the Pythagorean Theorem, meaning that [tex]a^2+b^2=c^2[/tex], with [tex]a[/tex] and [tex]b[/tex] being the length of the shorter of the three sides, and [tex]c[/tex] being the length of the hypotenuse, or the length of the longer of the three sides.

Matrix A has 2 rows and 3 columns whereas matrix B has3 rows and 2 column
Can AB be multiplied? Can BA be multiplied? Give the reason
Step-by-step explanation:
for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.
For AB
A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.
For BA
B has 2 columns and A has 2 rows it also matches so can be multiplied

The following exchange rate is given: £1 = 1.12 euros. Convert £9 into euros.
Answer:
10.08 Euro's
Step-by-step explanation:
Given that we know,
£1 = 1.12 Euro's.
To Simply convert it to Euro's you would multiply, 1.12 x 9 in order to find out what £9 is worth in Euro's.
Thus giving you,
10.08 Euro's
find the surface area of the cube below.
Answer:
150
Step-by-step explanation:
surface area =6a^2
= 6(5^2)
= 6×25
=150
Answer:
150 cm²
Step-by-step explanation:
So, firstly we must understand what does total surface area means (T.S.A)
We intuitively know that, it means,
Area of 6 EQUAL faces.
So,
Edge of the cube = 5 cm
Area of 1 face= 5 × 5= 25 cm²
Area of 6 faces= 25 × 6= 150 cm².
So, that means,
T.S.A= 150 Cm²

What is the distance points between the points 5,9 and 5,13?
Answer:
4 square units
Step-by-step explanation:
Hank's car travels 600 feet in 20 seconds. Andy's motorcycle travels 300 feet in 12 seconds. Which is faster, the car or the motorcycle? Explain your reasoning.
Answer:
the car travels faster
Step-by-step explanation:
Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2
600 divided by 2 = 300
Hank would have traveled 300 feet in 10 seconds
Andy traveled 300 feet at 12 seconds
Therefore Hanks car travels faster
Answer:
The car travels faster
Step-by-step explanation:
600 ft per 20 secs
How many feet in one sec?
600/20 = 30
Hank's car = 30 feet per second
300 feet in 12 sec
How many feet in one sec?
300/12 = 25
Andy's motorcycle = 25 feet per second

y = 3.5x + 4; A(...; 5), B(10; ...)
Answer:
y=3.5x+4; A(_,5) B(10,_)
Step-by-step explanation:
.Find point A: Substitute y value given, solve for x:
.
5=3.5x+4
1=3.5x
1/3.5=x

tan(A—B)=tanA—tanB/1+tanAtanB
Answer:
tan (A−B)=tan(A)−tan(B)/1+tan(A)tan(B)tan(A−B)=tan(A)−tan(B)/1+tan(A)tan(B)

Paul has a collection of nickels and
dimes that has
a total value of
& 12.50. He Has 150 coins in all. How
many dimes does paul have?
Answer:
#nickels = 50
#dimes = 100
Step-by-step explanation:
system of equations:
n + d = 150
.05n + .10d = 12.50
let n = '150 - d' and substitute this into the second equation
.05(150-d) + .10d = 12.5
7.5 - .05d + .10d = 12.5
.05d = 5
d = 5/.05
d = 100
n = 50

Ms Singh wants to buy a new television that costs £840
Each week, Ms Singh receives a wage of £300
She saves 40% of her wage each week.
Calculate how many weeks it will take Ms Singh to save enough money to
buy the television.
weeks
Some student
Cost of a television Ms. Singh wants to buy = £840
Ms. Singh's weekly wage = £300
Money she saves each week :
= 40% of her weekly wage
[tex] =\tt 40\% \: of \: 300[/tex]
[tex] = \tt \frac{40}{100} \times 300 [/tex]
[tex] =\tt \frac{40 \times 300}{100} [/tex]
[tex] =\tt \frac{12000}{100} [/tex]
[tex]\color{plum} = \tt£120[/tex]
Thus, Ms. Singh's weekly savings = £120
Number of weeks in which she will be able to buy a TV :
[tex] = \tt \frac{840}{120} [/tex]
[tex]\color{plum} =\tt 7 \: weeks[/tex]
Therefore, Ms. Singh will be able to buy a TV from her savings in 7 weeks.
Factorise x^2+11x+18
Answer:
(x + 9)(x + 2 )
Step-by-step explanation:
Sum =11
Product = 18
Factors = 9 , 2
When you multiply (9*2 = 18) and when you add (9 +2 = 11).
x² + 11x + 18 = x² + 9x + 2x + (9*2)
=x(x + 9) + 2(x + 9)
= (x + 9)(x + 2 )
Answer:
(x+9) (x+2)
Step-by-step explanation:
x^2+11x+18
x^2+9x+2x+18
x(x+9)+2(x+9)
(x+9) (x+2)

Answer:
X > 3/7Step-by-step explanation:
X > 3/7
We know that the student sleeps in at least 3 days, but we don't know what the exact number is, we use an inequality where X is greater than or equal to 3 out of the 7 days.
The radius of a circle is 12.8m. Find the circumference to the nearest tenth
Answer:
80.4
Step-by-step explanation:
The radius is 12.8m so to find circumference we have to multiply it by 2, 12.8x2 equals 25.6. Since we find our diameter we multiply 25.6 by pie or 3.14 and we 80.384 and round to the tenths place. Which is 80.4
