Find the perimeter of the smaller figure given that the two figures are similar.
Answers
: s2 = one of the sides of the smaller figure
: p1 = perimeter of the larger figure
: p2 = perimeter of the smaller figure
s1/s2 = p1/p2. The ratio of the corresponding sides is the same as the perimeter of the figures.
p1 = 30 + 30 + 35 + 5 + 10 = 110
s1 = 30 and s2 = 18
p1 = 110 and p2 is ?
s1/s2 = p1/p2
30/18 = 110/?
Crisscross ==== 30*? = 18*110
30*? = 1980
Divide both side by 30 ==== 30*?/30 = 1980/30
? = 66

The measure of an angle is 2.8.what is the measure of its complementary angle
Answers
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer:
87.2°Step-by-step explanation:
When angles are complementary, it means that they both add up to 90°.
In this case, one of the angles measures 2.8°.
So, to find the other one, we subtract 2.8 from 90.
90 - 2.8 = 87.2
The measure of the complementary angle is 87.2°

Nancy bought an extra-large bag of 1,100 beads to make necklaces. When she got home, she found another bag with 700 beads in it. If she uses all of the beads and uses 50 beads per necklace, how many necklaces can she make? A. 22 B. 14 C. 36 D. 400
Answers
Answer: C
Step-by-step explanation:
Given
Nancy bought the bag with 1100 beads to make necklaces
She found another bag with 700 beads
So, the total number of beads is the sum of two i.e. 1800 beads
It takes 50 beads per necklace
The number of necklaces that can be formed is
[tex]\Rightarrow \dfrac{1800}{50}\\\\\Rightarrow 36\ \text{Necklaces}[/tex]

What is the sun of the interior angles in the figure shown?
- 210
- 510
- 720
- 1080
Answers
Answer:
720°
Step-by-step explanation:
(180° x 6) - 360° = 720°
checking:
(right side) 2 angles 90° = 180°
(left side) 0ne pair of supplementary angles = 180°
(center) One angle 180° + ?°
One angle 180° - ?°
Equals 2 angles 180°
Total = 720°

Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?
Answers
Answer: 15 units
Step-by-step explanation:
Given
The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]
The length of the line segment is given by the distance formula i.e.
[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]
Insert the values,
[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]
Therefore, the length of line segment TU is 15 units

The diagram shows the floor plan of the stage at a theatre. (i put image) The stage is made from a rectangle and a semicircle, the rectangle is 16 m long and 5.5 m wide. Work out the total area of the stage
give your answer correct to 2 decimal places
Answers
Answer:
188.53 m²
Step-by-step explanation:
Total area of the stage = area of the rectangle + area of the semicircle
Area of rectangle = Length * Width
Length = 16 m
Width = 5.5 m
Area of rectangle = 16*5.5 = 88 m²
Area of semicircle = ½(πr²)
r = ½(16) = 8 m
Area = ½(π*8²)
Area = 100.53 m²
Total area of the stage = 88 + 100.53 = 188.53 m²

60% white, 40% black
The first draw you have a 60% chance drawing a white marble, the second time you have a 55% chance since you already drew one in the first round. so i think it is 60.5%% chance drawing white on both rounds since I add 60+55=121. 121/200=60.5%

Answers
Answer:
5 1/10 c or 3 1/10 +2
When you simplify the expression, you combine like terms. 5 7/10 c and -2 3/5 c are like terms. You multiply two on the numerator and denominator to make it 6/10. You subtract 2 6/10c from 5 7/10c to make it 3 1/10. This next step is easy. 8 and -6 are like terms. So you subtract 6 from 8 to get two. The final step is optional. 3 1/10 + 2= 5 1/10
