Which equation is correct? o 39 x 3 = 30 x 3 + 9x 3
o 39 x 3 = 30 +9x3
o 39 x 3 = 300 × 3+9×3
39×3=30×3+9
39x3=30x3+9x3
117=90+27
117=117
39x3=30+9x3
117=30+27
117=57
39x3=300x3+9x3
117=900+27
117=927
39x3=30x3+9
117=90+9
117=99
So the first one is correct.

At Ivanna's auto shop, it takes her 15 minutes to do an oil change and 24 minutes to do a tire change. Let x be the number of oil changes she does. Let y be the
number of tire changes she does.
Using the values and variables given, write an inequality describing how many oil changes and tire changes Ivanna can do in at most 2 hours (120minutes)
Plzzz help
Answer:
15x + 24y <= 120
Step-by-step explanation:
It takes 15 minutes per oil change, 15x
It takes 24 minutes per tire change, 24y
In at most 120 minutes, so it must be less than or equal to the time available.
Find the lateral surface area of the net below.
-26cm
-20cm
zlom
20cm
Record your answer, be sure to use the correct place value.
9514 1404 393
Answer:
1040 cm²
Step-by-step explanation:
The lateral surface area of the pyramid is the area of the four triangular faces. Each one has an area of ...
A = 1/2bh
A = 1/2(20 cm)(26 cm) = 260 cm²
Then the area of the four faces is ...
4 × 260 cm² = 1040 cm² . . . . lateral surface area

Answer:
D. 137 [tex]m^{2}[/tex]
Step-by-step explanation:
First, get the area of the rectangle:
[tex]A_{Rectangle} =length *width[/tex]
[tex]A_{Rectangle}=(15)(11)=165[/tex]
Then, get the area of the triangle:
[tex]A_{Triangle} =\frac{height*base}{2}[/tex]
[tex]A_{Triangle}=\frac{8*7}{2} =28[/tex]
Now substract the area of the triangle from the rectangle:
165 - 28 = 137
∴ 137 [tex]m^{2}[/tex]

2. (3 marks) A marketing company conducted a box office study and they found the following. The probability that a husband watches the movie Toy Story is 0.4 while the probability that a wife watches the movie is 0.5. The probability that a husband watches the movie, given that his wife does, is 0.7. (a) What is the probability that a married couple watches the movie
Answer:
0.35 = 35% probability that a married couple watches the movie
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
The probability that a husband watches the movie, given that his wife does, is 0.7.
This means that [tex]P(B|A) = 0.7[/tex]
The probability that a wife watches the movie is 0.5.
This means that [tex]P(A) = 0.5[/tex]
What is the probability that a married couple watches the movie?
Both, so:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
[tex]P(A \cap B) = P(B|A)*P(A) = 0.7*0.5 = 0.35[/tex]
0.35 = 35% probability that a married couple watches the movie
