Weight of an grapefruit=weight of an orange+8% weight of an orange
weight of an apple=weight of an orange -10% weight of an orange
a.<span>By what percentage is the grapefruit heavier than the apple?
We should find the connection between grapefruit and an apple. We know the connection between the weight of a grapefruit and an orange, we know the connection between an orange and an apple, so this means we know the connection between a grapefruit and an apple.
</span>
weight of an grapefruit=weight of an <span>orange+8% weight of an orange
</span>weight of an orange=weight of an apple<span> +10% weight of an apple
</span>
-> weight of an grapefruit=weight of an apple+10% weight of an apple + 8%(weight of an apple+10% weight of an apple)= weight of an apple + 18% weight of an apple + 2% weight of an apple= <span>weight of an apple + 20% weight of an apple
</span><span>b.By what percentage is the apple lighter than the grapefruit?
</span>weight of an grapefruit=weight of an apple + 20% weight of an apple<span>
</span>
-> The apple ts 20% lighter than the grapefruit.
Answer:
Sí, 2 • 10 = 20. Luego factoriza 10, que también es divisible entre 2 (2 • 5 = 10). Ambos factores son primos, por lo que puedes detenerte. La factorización prima de 20 es 2 • 2 • 5, la cual puedes escribir usando la notación exponencial como 22 • 5.

C. (0,0) which is the origin
Answer:
4
Step-by-step explanation:
For WX to be perpendicular to YZ, then the product of their slope must be -1
For slope of WX
W(2-3) and X(-4.9),
Mwx = 9-(-3)/-4-2
Mwx = 12/-6
Mwx = -2
For slope of Y(5. y), and Z(-1, 1),
Myz = 1-y/-1-5
Myz = 1-y/-6
Since Mwx•Myz = -1
-2•(1-y/-6) = -1
1-y/3 = -1
1-y = -3
-y = -3-1
-y = -4
y = 4
Hence the value of y is 4
