Answer
C. Yes, by SSS only
Step-by-step explanation:
Answer: y=4
Step-by-step explanation:
We have a khown angle wich is 30 degree .
Cos 30 = root square of 3 /2
So root sqaure of 3/2 = 4 root square 3 / x
X= 4 r.sq 3 / r.sq 3/2 = 8
So we just need to apply the pythagorian theorem
X^2= y^2+ 48
64 = y^2 +48
Y^2 = 16
Y=4
Answer:
a) Kylie has 8 marbles
b) 7 Cylinders
c) 17 carrots
d) 8 marbles belong to Shauntay
Step-by-step explanation:
5. Identify the type and subtype of each of the fol-
lowing problems.
a. Shawn has 15 marbles, which is 7 more marbles than Kyle has. How many marbles does Kyle have?
Shawn = 15 marbles
S = K + 7
15 = K + 7
K = 15 - 7
K = 8 marbles
Kylie has 8 marbles
b. Tiffany has 12 blocks, 5 of which are cubes and the rest cylinders. How many blocks are cylinders?
T = 12 blocks
Cubes = 5
Cylinders = the rest
12 blocks = Cubes + Cylinders
Cylinders = 12 - Cubes
Cylinders = 12 - 5
Cylinder = 7
c. Peter had some carrots. After he ate 3 of them, he had 14 carrots left. How many carrots did Peter have before?
Number of carrots Peter has before
= Number of carrots he ate + Number of carrots he has now
= 14 + 3
= 17 carrots
d. In a bag of 17 marbles, 9 marbles belong to Kelly and the rest belong to Shauntay. How many marbles belong to Shauntay?
Total number of Marbles = 17
Kelly = 9 marbles
Shauntay = ?
Total = Kelly + Shauntay
Shauntay = Total - Kelly's marbles
= ( 17 - 9) marbles
= 8 marbles
8 marbles belong to Shauntay
Answer:
The drawings are in the picture attached and the explanations are below.
Question 1.
Question 2:
- Equation: d = 10×8 lb - 8 lb
- Solution: d = 72 lb
Explanation:
<u>Question 1:</u>
- Statement 1: Mary was born, she weighet 8 lbs
- Statement 2: When she was 10 years old weighed 10 times as much
w = 10 × 8 lbs = 80 lbs
<u>Explanation of the drawing:</u>
<u />
Each cell represents 8 lbs, which was the weight when she was born. There are 10 cells, representing that the amount 8 lbs is repeated 10 times.
Then, the multiplication is represented an abbreviated sum:
- 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 = 10 × 8 = 80
<u>Question 2:</u>
- Statement: find the difference, d, between Mary's weight when she was 10 years old and when she was born.
d = 80 lbs - 8 lbs = 72 lbs
↑ ↑ ↑ ↑
difference 10 years old born solution
<u>Explanation of the drawing:</u>
- When you subtract one cell (8 lb) from ten cells (10 × 8 = 80 lb), you obtain nine cells ( 9 × 8 lb = 72 lb).
