Somebody help me with this one pls and if you did tysm

1. Ratio A is equivalent to Ratio B.

2. Ratio A is not equivalent to Ratio B.

3. Ratio A is equivalent to Ratio B.

Step-by-step explanation:

1. 8 questions out of 10 (or ) and 4 questions correct out of 5 (or ) are equivalent: Dividing the numerator of each fraction by its denominator will result in 0.8: 8/10 = 0.8, 4/5 = 0.8.

2. 15 prizes won in 40 attempts (or 15/40) and 3 prizes won in 10 attempts (3/10) are not equivalent:  15/40 = 0.375, vs  3/10 = 0.3

3. 3 cats for every 6 dogs (3/6) and 1 cat for every 2 dogs (1/2) are equivalent:  3/6 = 0.5. 1/2 = 0.5

Ratio A is equivalent to Ratio B.

Ratio A is not equivalent to Ratio B.

Ratio A is equivalent to Ratio B.

Step-by-step explanation:

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
