Answer:
B
Step-by-step explanation:
20 × 30 = 600
30 × 6 = 180
5 × 6 = 30
but 20 × 5 doesn't equal 10
Answer:
1.46 x 10⁶g
Step-by-step explanation:
Given parameters:
Weight of each bowling ball = 7.3 x 10³g
Number of balls in the bowling alley = 2.0 x 10²bowling balls
Unknown
The weight of the balls in the alley = ?
Solution:
To find the weight of the balls in the alley, multiply the mass of each balls with the total number of balls;
Weight of the balls = 7.3 x 10³ x 2.0 x 10²
Weight of the balls = (7.3 x 2.0) x 10³⁺²
Weight of the balls = 14.6 x 10⁵g
Therefore, the weight of the balls = 1.46 x 10⁶g
Answer: OPTION 3. -7
Step-by-step explanation:
Given
-52=-4x-5(-2x+2)
Distributive property (REMEMBER you need to change signs)
-52=-4x-5×(-2x)-5×2
-52=-4x+10x-10
Combine like terms (-4x and 10x)
-52=6x-10
Add 10 on both sides
-52+10=6x-10+10
-42=6x
Divide 6 on both sides
-42/6=6/6x
x=-7

Answer:
Step-by-step explanation:
From the figure attached,
In the given right triangles ΔADB and ΔCDB,
Statements Reasons
1). ∠BAD ≅ ∠BCD 1). Given
2). BD ≅ BD 2). Reflexive property
3). ΔADB ≅ ΔCDB 3). By LA theorem of congruence of right triangles
Therefore, there is sufficient information to prove the ΔADB and ΔCDB congruent.
Leg-angle theorem (L-A) will be used to prove the right triangles congruent.
The square root of 100 is 10
Hope this helps!
