Answer:
Luis will pay for three gloves and four bats = $ 270
Step-by-step explanation:
Let the bats be represented by b and gloves by g, then according to the given conditions
3b+ g= $135----equation 1
b+ 2g= $135------equation 2
Subtracting equation 2 from eq. 1 gives
3b+ g= $135----equation 1
<u>-b -2g= -$135------equation 2</u>
<u>2b -g = 0 --------- equation3</u>
2b-g= 0
or 2b= g------ equation4
This means price of 2 bats is equal to price of 1 glove.
Putting value of g in eq. 1 from eq. 4
3b+ 2b= $ 135
5b= $135
b= 135/5= 27
Price of 1 bat = $ 27 and price of 1 glove= 2*27= $54
Luis will pay for three gloves and four bats
= 54*3 + 4*27
= 162+ 108
= $ 270
Given two similar triangles
So, the corresponding angles are congruent, and the corresponding sides are proportional
As shown:
m∠ Y = 35, m∠ X = 90
So, m∠ W = 90 - 35 = 55
And the triangle XYW is similar to the triangle ECD
So,
Answer:
<u>a = 60° or π/3</u>
Step-by-step explanation:
<u>Given :-</u>
sin² a/2 - sin a/2 + 1/4
<u>To find :-</u>
a
<u>Solving :-</u>
sin² a/2 - sin a/2 + 1/4 = (sin a/2 - 1/2)² = 0
sin a/2 - 1/2 = 0
sin a/2 = 1/2
a/2 = 30°
<u>Solution :-</u>
<u>a = 60° or π/3</u>

Answer:
Square numbers
Step-by-step explanation:
if 1 is squared, you get 1.
if 2 is squared, you get 4.
if 3 is squared, you get 9.
if 4 is squared, you get 16.
And thus square numbers.
