Answer:
1/6
Step-by-step explanation:
P(8) = number of 8's / total = 1/3
Then keeping the card so we have 7 and 9
P(7) = number of 7's / total = 1/2
P(8, keep, 7) = 1/3 * 1/2 = 1/6
Simplest fraction form is "3/4"
Answer:
units²
Step-by-step explanation:
D and E lie on the x- axis and F is vertically below D
The triangle formed is right at D with legs of length 3 and 7
The area (A) of a right triangle is found using the formula
A = 
bh ( b is the base and h the perpendicular height )
here b = 3 and h = 7, hence
A = × 3 × 7 = units ²
Answer:
Step-by-step explanation:
Thanks to girls from relatives and earnings from an afterschool job, she has already saved $3700. If she's a seed in her goal of saving $150 per month, then if she saves for x months, the total amount that she would be have earned is
150x + 3700
1 year = 24 months
If she saves for 2 years, it means that the number of months for which she saved is 2 × 12 = 24 months. Therefore, the total amount
that she will have two years from now is
150 × 24 + 3700
= 3600 + 3700
= $7300
X=1.2
y=-10.7
-x+(-y)=-(1.2)+(-(-10.7)=-1.2+10.7=9.5
Answer: -x+(-y)=9.5
