Simplify the fraction. 11/55
Answer:
1/5
Step-by-step explanation:
That'll be one brainliest
Answer: 1/5
Step-by-step explanation:
You have to divide the numerator and the denominator by the GCF ( greatest common factor) of 11 and 55. 11 is the GCF of 11 and 55 so 11÷11=1 and 55÷11=5

A shape is made of 9 right triangles of equal size and three identical rectangles.
Each rectangle measures 7 mm wide by 3 mm high. The rectangles are each
7 mm wide by 3 mm high. What is the total area, in square millimeters,
of the shape?
Answer:
The area of the figure is 157.5 square millimeters.
Step-by-step explanation:
Since a shape is made of 9 right triangles of equal size and three identical rectangles, and each rectangle measures 7 mm wide by 3 mm high, while the rectangles are each 7 mm wide by 3 mm high, to determine what is the total area, in square millimeters, of the shape, the following calculations must be performed:
Area of a rectangle: base x height
Area of a triangle: (base x height) / 2
7x3 = 21 = Rectangle area
7x3 / 2 = 10.5 = Triangle area
21 x 3 + 10.5 x 9 = 157.5
Thus, the area of the figure is 157.5 square millimeters.
10. Multiply the following numbers using scientific notation. show the steps. (See Ex. 5)
(2 x 103)(3 x 104).
11. Divide the following numbers using scientific notation. Show the steps as they are done in the lesson. (See Ex. 6)
-42 x 102
14 x 103
Answer:
10) 6 × 10⁷
11) -3 × 10⁻¹
Step-by-step explanation:
Assuming that (2 x 103)(3 x 104) =
(2 × 10³)(3 × 10⁴) =
(2 × 10³) × (3 × 10⁴)
And the division of
(-42 x 102) and (14 x 103) =
(-4.2 × 10²) ÷ (1.4 × 10³)

Type the expression that results from the following series of steps:
Start with y, add 7, multiply by 3, then subtract 6.
Answer:
start with y
y
add 7
y+7
multiply by 3
3(y+7)
subtract 6
3(y+7)-6
therefore the answer is:
3y + 21 - 6
=
3y + 15 or 3(y+5)
What is the distance between the points? Round to the nearest tenth if necessary.(-4,-8) (2,2)
Answer: [tex]2\sqrt{34}[/tex] or, as a decimal, 11.7.
Step-by-Step Explanation:
1. Use the distance formula and substitute the values of the two ordered pairs.
[tex]\sqrt{(2-(-4))^{2}+(2-(-8))^{2}}[/tex]...
2. Multiply -1 by -4.
[tex]\sqrt{(2+4)^2+(2-(-8))^2\\}[/tex] ...
3. Add 2 and 4.
4. Raise 6 to the power of 2.
[tex]\sqrt{36+(2-(-8))^2}[/tex]...
5. Multiply -1 by -8.
6. Add 2 and 8.
7. Raise 10 to the power of 2.
[tex]\sqrt{36+100}[/tex] ...
8. Add 100 and 36.
9. Rewrite 136 as 2² · 34.
10. After factoring 4 out of 136 and rewriting as ... [tex]\sqrt{2^{2}(34)}[/tex], pull out terms from under the radical. It should look like this now: [tex]2\sqrt{34}[/tex]. That is your final answer!!
Hope that helps! Note: the unrounded decimal is 11.66190378.

Find the measures of the interior angles of the triangle
Answer:
m∡A = 59°
m∡B = 48°
m∡C = 73°
Step-by-step explanation:
'x' = measure ∡A
73 + x - 11 + x = 180
2x + 62 = 180
2x = 118
x = 59

Two forces of newtons and newtons act on a point. The resultant force is newtons. Find the angle between the two forces.
Question: Assume the complete question as, Two forces of 20 Newton’s and 30 Newton’s² act on a point. The resultant force is 40 Newton’s. Find the angle between the two forces
Answer:
75.5°
Step-by-step explanation:
From the question,
Using cosine rule,
R² = P²+Q²-2PQcosθ................... Equation 1
Where θ angle between the the two forces.
Given; R = 40 Newton, P = 20 Newton, Q = 30 Newton.
Substitute these values into 1
40² = 20²+30²-[2×20×30(cosθ)]
1600 = 400+900-(1200cosθ)
1600 = 1300-1200cosθ
1200cosθ = 1600-1300
1200cosθ = 300
cosθ = 300/1200
cosθ = 0.25
θ = cos⁻¹(0.25)
θ = 75.5°
Hence the angle between the forces is 75.5°
