the lenghts of two in an isosceles triangle are 8 cm and 4 cm then the perimeter of the triangle is ............cm
1. 16
2. 8
3. 20
4. 12
Step-by-step explanation:
sides are 4cm, 8cm, 8cm ----( because isosceles triangle have 2 sides equal )
so, perimeter = sum of all sides
= 4 + 8 + 8
= 20cm-------------------------------------FOLLOW MECAN SOMEONE PLEASE HELP ME WITH THESE 2.

What is the measure of angle LMN ?
Answer:
g = 9°
hence LMN = 135 + 18 = 153°
Step-by-step explanation:
straight line is 180°
180 - 18 = 162
162 = 18g
g = 9
Answer:
Step-by-step explanation:
So try to find the total angle so
15g+18+3g=180
18g=180-18
18g=162
g=9
angle LMN=15x9+18
=135+18
LMN=153 degrees
angle PMN=3x9
= 27 degrees
The figure shows four smaller squares in the corners of a large square. the smaller squares have sides of length 1cm, 2cm, 3cm and 4cm in anticlockwise order and the sides of the large square have length of 11cm.
What is the area of the shaded quadrilateral? (see attachment)
Answer:
B. 36 [tex]cm^{2}[/tex]
Step-by-step explanation:
The shaded quadrilateral has a shape of a trapezium.
Area of a trapezium = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the side length parallel to the base, b is the base and h is the height.
The height of the figure = 11 - (4 + 1)
= 11 - 5
= 6
The height of the figure is 6 cm.
The length of its base = 11 - (1 + 2)
= 11 - 3
= 8
The length of its base is 8 cm.
The length of the side parallel to base = 11 - (4 + 3)
= 11 - 7
= 4
The parallel side length to base is 4 cm.
Area of quadrilateral = [tex]\frac{1}{2}[/tex](a + b)h
= [tex]\frac{1}{2}[/tex](4 + 8)6
= 12 x 3
= 36
Area of quadrilateral = 36 [tex]cm^{2}[/tex]

Of the last 14 trains to pull into Brookfield Station, 10 were full. Considering this data, how many of the next 7 trains would you expect to be full?
Answer:
5
Step-by-step explanation:
Hello There!
This question has to do with proportionalities
The first thing we want to do is create a proportional relationship between the total amount of trains to the amount of trains that are full
It said that out 14 trains 10 were full
so the proportional relationship would be
10 to 14
now we want to find how many trains would be full out of 7
to do so we set up an equation using our formed proportion
let x = number of full trains
[tex]\frac{10}{14} =\frac{x}{7}[/tex]
now we solve for x
to solve for x we want to isolate the variable (x) and get rid of the 7
to do so we multiply each side by 7
[tex]\frac{x}{7} 7=x\\\frac{10}{14} 7=5[/tex]
we're left with x = 5
hence we can expect 5 trains to be full out of 7

Answer:
Mean: 8.27 minutes
Median: 8
Mode: 8
Range: 9
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
To find the median you would add up all of the numbers and divide by the number of numbers in the data set. The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median.
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
Hope this helps!!!

Can someone please help me with math
Answer:
B
Step-by-step explanation:
they want us to find the equation in slope intercept form
which is y= mx + b
where m = slope and b = y intercept
the slope is change in y over change in x
as y goes up 1 x goes up 1 so the slope is 1 or m=1
the y intercept is at point (0,1)
so the y intercept is 1
now we add it all together and get that the equation Is
y=x+1

how do i make a area model of 4.6 and 3
Answer:
Area model is one of a simple step to understand the given situation. So to make it simple, we need to decompose the number.
given number = 4.6 and 3
First we need to get the whole number and start multiplying:
Whole number of 4.6 => 4
whole number of 3 => 3
Now, let’s start multiplying the whole number
=> 4 x 3
=> 12
Then let’s multiply the remaining decimal:
=>.6 x 3
=> 1.8
Then add
=> 12 + 1.8
= 13.8
we know that
The area model for multiplication is a pictorial way of representing
multiplication. In the area model, the length and width of a rectangle
represent factors, and the area of the rectangle represents their product
So
in this problem
the factors are
l e n g t h 4.6 w i d e 3
decompose the number
4.6
4.6 = ( 4 + 0.6 ) A r e a o f r e c t an g l e = A r e a r e ct a n g l e 1 + A r e a re c t a n g l e 2 = ( 4 + 0.6 ) ∗ 3 = 4∗ 3 + 0.6 ∗ 3 = 12 + 1.8 = 13.8
see the attached figure to better understand the problem
therefore
the answer is
the product of
4.6
and
3
is equal to
13.8

An item is regularly priced at $60 . Lucy bought it on sale for 60% off the regular price. How much did Lucy pay?
Answer:
$24
60% of 60 is 36 so to subtract 60% from the total $60 you would do 60-36=24
Function f approximately represents the trajectory of an airplane in an air show, where x is the horizontal distance of the flight, in kilometers. What is the symmetry of the function?
Answer:
[tex](\frac{3}{2},102)[/tex]
Step-by-step explanation:
Given
[tex]f(x)=88x^2-264x+300[/tex] --- Missing from the question
Required
The symmetry
First, we express f(x) as: [tex]f(x) = a(x - h)^2 + k[/tex]
Where the symmetry is: (h, y) and x = h
Equate f(x) to 0
[tex]88x^2-264x+300 = 0[/tex]
Subtract 300 from both sides
[tex]88x^2-264x+300 - 300= 0 - 300[/tex]
[tex]88x^2 - 264x= - 300[/tex]
Factorize
[tex]88(x^2 - 3x) = -300[/tex]
On the left-hand side, the coefficient of x is -3.
Divide by 2 and add the square to both sides.
So, we have:
[tex]88(x^2 - 3x) + (\frac{3}{2})^2 = -300 + (\frac{3}{2})^2[/tex]
Multiply the new terms by 88 (to make it factorizable)
[tex]88(x^2 - 3x ) +88* (\frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
Factorize
[tex]88(x^2 - 3x + (\frac{3}{2})^2) = -300 + 88 * (\frac{3}{2})^2[/tex]
The quadratic expression in the bracket is a perfect square. This gives:
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * \frac{9}{4}[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 22 * 9[/tex]
[tex]88(x - \frac{3}{2})^2 = -102[/tex]
Add 102 to both sides
[tex]88(x - \frac{3}{2})^2 +102= -102 + 102[/tex]
[tex]88(x - \frac{3}{2})^2 +102= 0[/tex]
Equate to y
[tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
Recall that:
The symmetry is: (h, y)
By comparison with [tex]f(x) = a(x - h)^2 + k[/tex] and x = h
[tex]h = \frac{3}{2}[/tex]
So: [tex]x = \frac{3}{2}[/tex]
Substitute [tex]x = \frac{3}{2}[/tex] in [tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(\frac{3}{2} - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(0)^2 +102[/tex]
[tex]y = 0 +102[/tex]
[tex]y = 102[/tex]
So, the symmetry is: [tex](\frac{3}{2},102)[/tex]
