Answer:
156.6 meters squared
Step-by-step explanation:
There are 3 triangles for the sides. The area for a triangle is one half base times height. So we are doing one half of 9 times 9. This is 40.5. Since there are 3 of them we can just multiply 40.5 times 3 to get 121.5. And now to solve for the base triangle, it is one half of 9 times 7.8. We get 35.1. Now add together 121.5 and 35.1. We get 156.6. Now since this is surface area it is meters squared.

A) the arrow has nothing to do with numbers.
B) the arrow always points to the largest side.
the arrow always points to the smallest side
D) the opening of the arrow is always on the smallest side.
Answer:
C) the arrow always points to the smaller side
Step-by-step explanation:
if you struggle to remember think of it as a crocodile going for the highest amount of 'food', in this case the food is the number
Answer: C, the arrow always points to the smallest side.
Step-by-step explanation:
A way of remembering which way the '>' sign goes is to think of it as a crocodile mouth (the open bit) and the crocodile wants the most food (the biggest number).

A cardboard box in the shape of a rectangular prism has the dimensions shown. Write a polynomial in standard form to represent the volume of the box.
Answer:
[tex]Volume = x^3 +3x^2 -16x +12[/tex]
Step-by-step explanation:
Given [missing from the question].
The dimensions are:
Length =(x + 6), Width = (x - 2) and Height = (x -1)
Required
Represent the volume as a polynomial
Volume is calculated as:
[tex]Volume = Length * Width * Height[/tex]
So:
[tex]Volume = (x + 6) * (x - 2) * (x - 1)[/tex]
Expand
[tex]Volume = (x + 6) * (x^2 -2x -x +2)[/tex]
[tex]Volume = (x + 6) * (x^2 -3x +2)[/tex]
Expand
[tex]Volume = x^3 -3x^2 +2x +6x^2-18x +12[/tex]
Collect like terms
[tex]Volume = x^3 -3x^2+6x^2 +2x -18x +12[/tex]
[tex]Volume = x^3 +3x^2 -16x +12[/tex]
The ratio of the perimeters of two squares is 2:3. If the
area of the larger square is 324 square feet, what is the length, in feet, of the side of the smaller square?
Where the above ratio are given, the length of the side of the smaller square is approximately 14.7 feet.
How to compute the aboveThe area of a square is calculated by squaring the length of its side. Given that the area of the larger square is 324 square feet, we have:
(3/2)x² = 324
To solve for x, we can rearrange the equation and take the square root of both sides -
x² = (324 * 2) / 3
x² = 216
x ≈ √216
x ≈ 14.7
Hence , the length of the side of the smaller square is approximately 14.7 feet.

In a baseball card collection, 40% of the cards are worth more than $100. If 12 cards in the collection are worth more than $100, how many total baseball cards are in the collection?
Answer:
30
Step-by-step explanation:
Total number of cards = number of cards worth more than 100 divided by the rate of those cards among total cards = 12/40% = 30

SOLVE FOR X!!
(will mark brainliest)
Answer:
19
Step-by-step explanation:
Since it is a 90° angle we can say that 3x-15+2x+10 = 90.
3x-15+2x+10 = 90
5x-5=90
5x=95
x=19
By solving this we find that x is equal to 19.
Answer:
19
Step-by-step explanation:
3*19 = 57
57 - 15 = 42
2*19 = 38
38 + 10 = 48
48 + 42 = 90
(As this is a 90 degree angle)
Find the value of x in each diagram.
Answer:
4. 25 5. 80 6. 30
Step-by-step explanation:
All triangles add up to 180.
The triangle in #4 is right, so 90° + 65° = 155°
180° - 155° = 25°
x=25
#5.
50° + 50° = 100°
180° - 100° = 80°
x=80
In #4 the triangle is an equilateral, so all the angles will be equal. 2x + 2x + 2x = 180
6x = 180
x = 30
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
Two of the angle measures are given in each triangle so to find the third angle measurement we need to subtract the sum of two of the interior angles
4.
180 - (65 + 90) = x
180 - 155 = x
25 = x
5.
180 - (50+5) = x
180 - 100 = x
80 = x
For the 6th question all side lengths are equal so the angle measures also equal and 60 each
2x = 60
x = 30
SOLVE FOR X TO THE NEAREST TENTH
Answer:
x = 8.8
Step-by-step explanation:
First, you have to solve the side length for the smaller triangle.
[tex]c= \sqrt{ a^{2} +b^{2} }\\c= \sqrt{5^{2}+4^{2} } \\\\c=\sqrt{25+16} \\c=\sqrt{41} \\c= 6.4\\[/tex]
Now for the bigger square.
[tex]c= \sqrt{ a^{2} +b^{2} \\} \\c = \sqrt{6.4^{2} +6^{2} } \\c= \sqrt{40.96+36} \\c= \sqrt{ 76.96}\\c= 8.77\\[/tex]
Rounded to the nearest tenth = 8.8
