Answer:
50.7%
Step-by-step explanation:
First you have to find the difference. (190-126=64) Then to find the percentage you have to divide A by B (64/126 which is about .507) Move the decimal I’ve twice (50.7) and there’s your answer!
<em>Answer:</em>
<em>(True)</em>
<em>Yes they form a liner pair.</em>
<em>Step-by-step explanation:</em>
<em>They form a because supplementary angles are two angles the sum of whose measures is 180º, so they can form a liner pair. Sometimes they may be be two separate angles. Linear pairs are adjacent angles who share a common ray and whose opposite rays form a straight line. </em>

Answer:
A is the answer probably.
plz mark as brainliest
I'd need to see a picture of the angles. All I can say is that complementary angles add up to 90 degrees and supplementary angles add up to 180 degrees, and I'm assuming the answer is one of those two
Answer:
- about 243.9 cm³
- 35828 4/7 cm² = 3 102/175 m²
Step-by-step explanation:
<h3>1.</h3>
The 8-cm diameter sphere has a radius of 4 cm. The volume of it is given by ...
V = 4/3πr³ = 4/3π(4 cm)³ = 256/3π cm³
The 8-cm cube has a volume of ...
V = s³
V = (8 cm)³ = 512 cm³
The volume of the empty space is the difference of these volumes:
space = 512 cm³ -256/3π cm³ = 256(6 -π)/3 cm³
space ≈ 243.9 cm³

<h3>2.</h3>
The area of a hemisphere is twice the area of a circle with the same radius. Then the area of the top and bottom of the birdbath will be 2+1 = 3 times the area of a circle with radius 30 cm.
top+bottom area = 3 × πr² = 3 × 22/7(30 cm)² = 8485 5/7 cm²
The lateral area of the cylinder is ...
LA = 2πrh
= 2(22/7)(30 cm)(145 cm) = 27342 6/7 cm²
Then the total surface area of the birdbath is ...
total area = top+bottom area + lateral area
total area = 8485 5/7 cm² +27342 6/7 cm² = 35828 4/7 cm²
= 3 102/175 m²
