Answer:
sum of ratio =3+2=5
David'share=£9900x3/5=£5940
Sum of ratio for part= 4+4+2=10
for himself=£5940x4/10=£2376
for wife=£5940x4/10=£2376
for son=£5940x2/10=£1188
his wife gets over son
£2376-£1188=£1188
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10.If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
2.16 • 10^-1
3, because if it only makes 10 cupcakes, you need to triple it (i.e. 10*3=30); (Assuming it was 1 cup oil) 3 cups vegetable oil; 3 cups flour; the difference is 2 teaspoons; (Assuming it was 1 teaspoon salt) the difference is 2 teaspoons; It would make sense to round the bananas because "medium-sized bananas" depends on your personal opinion, which means it's already rounded and further rounding wouldn't hurt as long as you're careful.
<span>multiplying and dividing is similar adding and subtracting. When the signs are different the answer is negative. When the signs are the same the answer is positive</span>
Answer:
B. No, the slope of the line perpendicular to the line 3x + 2y = –11 should be 2/3.
Step-by-step explanation:
The slope of a perpendicular line is the opposite of the reciprocal of the slope of the original. Simon correctly computed the original line's slope to be -3/2. He correctly computed the reciprocal of that to be -2/3, but failed to recognize that the slope of the perpendicular line is the opposite of this, 2/3.
Simon's work is correct otherwise.
