Simplify \(\frac{1\frac{7}{8} \times 2\frac{2}{5}}{6\frac{3}{4} \div \frac{3}{4}}\)
90o
4\(\frac{1}{2}\)
2
\(\frac{1}{2}\)
Correct answer is D
\(\frac{1\frac{7}{8} \times 2\frac{2}{5}}{6\frac{3}{4} \div \frac{3}{4}}\)
from numerator \(1 \frac{7}{8} \times 2 \frac{2}{5}\)
= \(\frac{15}{8} \times \frac{12}{5}\)
= \(\frac{3 \times 3}{2 \times 1} = \frac{9}{2}\)
from denominator \(6\frac{3}{4} \div \frac{3}{4}\)
= \(\frac{27}{4} \div \frac{3}{4}\)
= \(\frac{27}{4} \times \frac{4}{3}\)
= \(\frac{9 \times 1}{1 \times 1} = \frac{9}{1}\)
\(\frac{9}{2} \div \frac{9}{1} = \frac{9}{2} \times \frac{1}{9}\)
= \(\frac{1}{2}\)
In what number base is the addition 465 + 24 + 225 = 1050?
ten
nine
eight
seven
Correct answer is D
No explanation has been provided for this answer.
1
\(\frac{3}{2}\)
2
\(\frac{5}{2}\)
Correct answer is B
9(2 - x) = 3
32(2 - x) = 3
2(2 - x) = 1
4 - 2x = 1
-2x = 1 - 4
-2x = -3
x = \(\frac{-3}{-2}\)
x = \(\frac{3}{2}\)
Multiply 2.7 x 10-4 by 6.3 x 106 and leave your answers in standard form
1.7 x 103
1.70 x 103
1.701 x 103
17.01 x 103
Correct answer is C
2.7 x 10-4 x 6.3 x 106
= 2.7 x 6.3 x 10-4 x 106
= 17.01 x 10-4 + 6
= 17.01 x 102
= 1.701 x 101 x 102
= 1.701 x 101 + 2
= 1.701 x 103
The diagram is a polygon. Find the largest of its interior angles
300o
100o
120o
150o
Correct answer is D
Sum of interior angles = 3602
i.e 3x + 2x + 2x + x + 4x = 360o
12x = 360
x = \(\frac{360}{12}\)
x = 30o
x + c = 180
30o + c = 180
c = 180 - 30
c = 150o
