An isosceles triangle has base 56 mm and
perpendicular height 45 mm
45 mm .
Work out the perimeter of the large triangle.
THE BASE OF THE LARGE TRIANGLE IS 168 Give your answer in mm.
Your final line should say, perimeter = ... m
Answer:
Step-by-step explanation:
Draw the altitude from the vertex angle to the base. You have two congruent, right triangles. The hypotenuse of each triangle is
√[(56/2)²+45²] = √[28²+45²] = √2809 = 53 mm
perimeter of larger triangle = 2×53 + 56 = 162 mm

Answer:
The solution of the first image is: b = √48
The solution of the second image is: c = √125
Step-by-step explanation:
Here we have two triangle rectangles, first, we need to remember the Pythagorean theorem.
For a triangle rectangle with cathetus A and B, and a hypotenuse H, we have the relationship:
A^2 + B^2 = H^2
Where H is the side that is opposite to the right angle (the angle of 90°)
In the first image, we can see that the hypotenuse is equal to 8, and one cathetus is equal to 4.
We want to find the value of b, that is the other cathetus.
Then we have:
4^2 + b^2 = 8^2
b^2 = 8^2 - 4^2
b^2 = 48
b = √48
Second image:
in this case, c is the hypotenuse, a and b are the cathetus.
We know that:
a = 5, b = 10
Then we have the equation:
a^2 + b^2 = c^2
Now we can replace the above values:
5^2 + 10^2 = c^2
25 + 100 = c^2
125 = c^2
√125 = c

9 liters = 9000 cm^3
(50x40xH) = 9000
H = 4.5 cm
Derek’s limo company charges $5.00 to rent a limo, and an additional $12.00 per mile that the limo drives. Frank’s limo company charges $85.00 to rent the limo, but only $8.00 per mile. Write a LEGEND and a SYSTEM OF EQUATIONS that shows the cost of both limo companies. *
Answer:
110
Step-by-step explanation:
it cost 110 all together because if you add 17 and 93 that's what it is which was 110. I got 17 from when I add 5 + 12 and I added 85 + 8 that's how I got the answer

Answer:
Step-by-step explanation:
Problem One
Perimeter is in meters not square meters. The equation is
2*(6.8+x) + 2*12.5= 47 Remove the brackets. Combine like terms
13.6 + 2x + 25 = 47
38.6 + 2x = 47 Subtract 38.5 from both sides
2x = 47 - 38.6
2x = 8.4 Divide by 2
x = 4.2
Answer D
Problem 2
This problem is asking that you calculate the perimeter of a swimming pool.
The two semicircles on the ends make a whole circle.
The diameter of the semicircles is obtained from the difference of the two given lengths.
The rectangle has a length of 12. The length of the rectangle and the 2 semicircles is 16. The difference is 4. You could divide this by 2 to get the radius. I would just leave it as the diameter.
So the perimeter is pi*d + 2 * 12 [there are 2 lengths]
Perimeter = 4*pi + 24
Perimeter = 12.56 + 24
Perimeter = 36.56
Answer A
Problem 3
This is the circle inside the square.
The radius of the circle = 9
The diameter of the circle and the length of square's side = 2*9 = 18
The area of the square = s^2 where s = 18
The area of the square = 18^2 = 324
The area of the circle = pi * 9^2 = 3.24 * 81 = 251.34
The area of the Shaded area = 324 - 251.34 = 69.66
Answer C
Problem 4
b1 = 5
b2 = 11.5
h = 4.5
Formula
Area = (b1 + b2 ) * 4.5/2
Area = (5 + 11.5) * 4.5 /2
Area = 16.5 * 4.5 / 2
Area = 74.25/2
Area = 37.125
Answer D
please help me answer this question!!!!!
Answer:
h = 13ft
Step-by-step explanation:
We can assume that the triangles are similar, so:
5 ft is to 26 ft as 2.5 ft is to h ft.
Which can be set up like this:
[tex]\frac{5}{2.5}=\frac{26}{h}[/tex]
We can cross multiply:
5h = (2.5) (26)
5h = 65
h = 13ft

a bag contains 4 blue and 6 green marbles. two marbles are selected at a random from the bag. if the first marble is not replaced before the second marble is drawn
Answer:
4 ÷ 10
Step-by-step explanation:
The computation of P is shown below:
If we add two marbles i.e.
= 4 + 6
= 10 marbles
Now if we draw the second marble
P(blue) = Blue marbles ÷ total marbles
= 4 ÷ 10
In the other case
P( blue second given a green first) = 4 ÷ 10
A 4-foot tree was planted in 1984. The tree grows continuously by 22% each year from this point forward. Find the height of the tree after 8 years.
Answer:
the tree will be 11.04 feet tall
Step-by-step explanation:
4 x 0.22 (22%) = 0.88
every year it grows 0.88 foot.
0.88 x 8 = 7.04
4 + 7.04 = 11.04 feet tall
sorry if this is wrong!
The height of the tree after 8 years will be 11.04 feet.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a 4-foot tree was planted in 1984. The tree grows continuously by 22% each year from this point forward.
The height after 8 years will be calculated as:-
4 x 0.22 (22%) = 0.88
Every year it grows 0.88 feet.
0.88 x 8 = 7.04
4 + 7.04 = 11.04 feet tall

Robert is an avid runner who as a specific route he runs each morning. He leaves his house and runs 3
miles north before stopping for a 1 minute break. After his break he runs 4 miles east before taking a 2
minute break. Next he runs 5 miles southwest back to his home. What is his average speed if the route
without the breaks takes 57 minutes to complete?
Answer:
he's running 4/19 miles per minute or 12.6 miles per hour
Step-by-step explanation:
he is running 3 miles north, 4 miles east, and 5 miles southwest, a total of 12 miles
d = rt
12 = 57r
r = 12/57 or 4/19 (simplest form)
this is 4/19 miles per minute, multiply by 60 and it's about 12.6 miles per hour

[tex]3x^{2}[/tex] - 2[tex]x[/tex] - 5
(Multiply 3 from [tex]3x^{2}[/tex] with -5)
Product = -15
Sum = -2
