Step-by-step explanation:
Mrs. Casiple is making a table cloth for her circular dining table 10 dm in radius. She wants the cloth to be hanging around the edge of the table by 4 dm. How big will the table cloth be? Use π=22/7
The area of the dining tablecloth would be 616 dm² which is a circular dining table 10 dm in radius.
What is the area of the circle?The area of the circle is equal to the product of the square of the radius of the circle and pi.
A = πr²
where 'r' is the radius of the circle
Mrs. Casiple is making a tablecloth for her circular dining table 10 dm in radius. She wants the cloth to be hanging around the edge of the table by 4 dm which is given in the question.
Here the radius of the dining table = 10 dm.
The extra length = 4 dm
Total radius = 10 dm + 4 dm = 14 dm
Area of dining table cloth = πr²
Area of dining table cloth = 22/7 × (14)²
Area of dining table cloth = 616 dm²
Therefore, the area of the dining tablecloth would be 616 dm²

If the expression [tex]\frac{3^a*\sqrt{6} }{9*\sqrt{54} }[/tex] is equal to 1, what is the value of a?
A. 1
B. 2
C.3
D.4
Answer:
[tex]C.3[/tex]
Step-by-step explanation:
[tex]We\ are\ given:\\\frac{3^a*\sqrt{6} }{9*\sqrt{54}}=1\\Hence,\\By\ using\ one\ of\ the\ Laws\ of\ Exponents:[\frac{x^a}{y^a}]=[\frac{x}{y}]^a\\Hence,\\\frac{3^a*\sqrt{6} }{9*\sqrt{54} }=1\\ \frac{3^a}{9}*\frac{\sqrt{6} }{\sqrt{54} } =1\\Hence,\\\frac{3^a}{9}*\sqrt{\frac{6}{54} }=1\\ \frac{3^a}{9}*\sqrt{\frac{1}{9} }=1\\\frac{3^a}{9}*\frac{1}{3}=1\\\\3^a=3*9\\3^a=27\\3^a=3^3\\As\ the\ bases(3)\ is\ equal,\ the\ exponents\ are\ equal\ too.\\Hence,\\a=3[/tex]
2. One angle of a triangle measures 10 degrees more than the second. The measure of the third angle is twice the sum of the measures of the first two angles. Find the measure of each angle. [Hint: the sum of the three angles in a triangle equals 180°.] PLEASE SHOW YOUR WORK I WILL MAKE BRAINLIST PLEASE!!!!!!!
Answer:
first angle = 25 degrees
Second angle = 35 degrees
Third side = 120/degrees
Step-by-step explanation:
Let the size of the second angle be x degrees.
One angle of a triangle measures 10 degrees more than the second. This means that the size of the first angle is ( x+ 10 )degrees.
The measure of the third angle is twice the sum of the measures of the first two angles. This means that The third angle = 2( first angle + second angle). So the size of each angle is
First angle (x + 10) degrees
Second angle = x degrees
Third angle = 2(x + 10 + x) = (4x + 20) degrees
Sum of angles in a triangle = 180 degrees. Therefore, x + 10 + x + 4x + 20 = 180 degrees 6x + 30 = 180
6x = 180 - 30 = 150
x = 150/6 = 25 degrees
First angle = x + 10 = 25 +10 = 35
Third angle = 4x + 20 = 4 × 25 + 20
= 100+ 20 = 120 degrees
Hope this helps
Answer:25(1st angle),35(2nd angle),120(3rd angle)
Step-by-step explanation: (/ stands for divide)
180/6=30 (sum of angles/total units=value of one unit, third angle is 4 units as it is twice the sum of first two angles)
30x4=120 (value of unitxnumber of units of 3rd angle=3rd angle)
30x2=60 (value of unitxfirst angle+second angle total units=value of 1st angle+2nd angle)
(60-10)/2=25(1st angle)
25+10=35(2nd angle)
CHECK: 35+25+120=180
hope you get it :)
