Answer:
-72 y^4
Step-by-step explanation:
(8y^2)(-9y^2)
Multiply the coefficients
8*-9 = -72
Add the exponents since the bases are the same
y^2 * y^2 = y^(2+2) = y^4
(8y^2)(-9y^2) = -72 y^4

Answer:
90°
Step-by-step explanation:
step 1
Find the measure of angle b
we know that
(m∠b+90°)=124° ----> by vertical angles
so
m∠b=124°-90°
m∠b=34°
step 2
Find the measure of angle c
(m∠c+124°)=180° ----> by supplementary angles (form a linear pair)
m∠c=180°-124°
m∠c=56°
step 3
Find the measure of angle a
m∠a=m∠c ----> by vertical angles
so
m∠a=56°
step 4
Find the value of m∠ a + m∠b
m∠a=56°
m∠b=34°
m∠ a + m∠b=56°+34°
m∠ a + m∠b=90°
First find the percentage Pablo got on the spelling:
21/25 = 0.84
0.84 * 100 = 84 ( To convert into a percent)
Therefore Pablo scored less that 85%
