Answer:
Step-by-step explanation:
Since both the triangles are similar, their sides will be in proportion. As one side is getting doubled, by SSS test of similarity, all the other sides will get doubled as well.
As the perimeter of a triangle is sum of its sides, the doubling of all sides will result in doubling of the perimeter.
Hence, perimeter of 2nd triangle = 14 cm.
Given:
The bakers at Healthy Bakery can make 170 bagels in 2 hours.
To find:
How many bagels can they bake in 14 hours and the rate per hour.
Solution:
We have,
Number of bagels the bakers can bake in 2 hours = 170 bagels
Number of bagels the bakers can bake in 1 hours = 
bagels
= 85 bagels
Therefore, the average rate is 85 bagels per hour.
Number of bagels the bakers can bake in 14 hours = 
bagels
= 1190 bagels
Therefore, the bakers can bake 1190 bagels in 14 hours.
(-1/4)x + 2 = 8
Multiply all terms by 4.
(-1)x + 8 = 32
Simplify.
-x + 8 = 32
Subtract 8 from both sides.
-x = 24
Multiply both sides by -1.
x = -24.
<h3>The value of x is equal to -24.</h3>
-1/4(-24) + 2 = 8
Answer:
2.a)31°
b)135°
3.a)72°
Step-by-step explanation:
2a) Angles in a straight line add up to 180°
180-62=118°
since in an isosceles triangle base angles are equal 62÷2=31°
b)sum of interior angles=180(n-2)
180(8-2)=1080°
each angle is 1080÷8=135°
3.a) Exterior angle=360/n
=360÷5=72° each
