Which expression represents the area of triangle ABC in square meters?
A. 1/2 x 14 x 57
B. 1/2 x 14 x 64
C. 1/2 x 24 x 40
D. 1/2 x 24 x 57
Answer:
A. 1/2 x 14 x 57
Step-by-step explanation:
The formula for the area of a triangle is base x height x 1/2
To calculate the base you would need to add the two numbers on the bottom of the triangle: 20 + 37 = 57
The photo shows that the height is 14 so it would be
1/2 x 14 x 57
Formula of area of triangle-1/2
The base is 20+37 =57
so the answer is 1/2*57*14

Hayden drives a taxi cab and receives $200 a day plue $0.25 for every mile he drives. He is saving up for a new laptop that costs about $1800. If Hayden drives an average of 300 miles per day, how many days will he have to drive to save enough money to buy the laptop?
Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.
Given:
Daily base pay = $200
Earnings per mile driven = $0.25
Cost of the laptop = $1800
Average miles driven per day = 300
The basic arithmetic operations have been used to solve this question
1. Calculating the total earnings per day.
Total earnings per day = Daily base pay + (Earnings per mile driven × Average miles driven per day)
Total earnings per day = $200 + ($0.25 × 300)
Total earnings per day = $200 + $75
Total earnings per day = $275
2. Determining the number of days required to save enough money for the laptop.
Number of days = Cost of the laptop ÷ Total earnings per day
Number of days = $1800 ÷ $275
Number of days ≈ 6.545 (rounded to the nearest whole number)
Therefore, Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.

Which Ratios are equivalent to 24:4? Choose ALL the equivalent ratios
Answer:
6:1 and 12:2. cuz if u multiply each, you will eventually get 24:4
Step-by-step explanation:
If the result of the two ratios are same, then they are said to be equivalent ratio.
The ratio which is equivalent to the given ratio are 6:1 and 12:2. Thus the option A and C is the correct option.
What is equivalent ratio?Equivalent ratio is the ratio which is same in the value as the original ratio but the numerator and denominator is different for both the ratios.
Given information-
The ratio given in the problem is,
[tex]24:4[/tex]
Let r is the ratio, then it can be written as,
[tex]r=\dfrac{24}{4}\\[/tex]
Simplify it,
[tex]r=\dfrac{6}{1}[/tex]
[tex]r=6:1[/tex]
Check all the options which is equivalent to the ratio 6:1.
A) The ratio given in the option A is[tex]6:1[/tex]
Which is equal tot he given ratio. Thus the option A is correct option.
B) The ratio given in the option B is[tex]8:4[/tex]
Let r is the ratio, then it can be written as,
[tex]r=\dfrac{8}{4}\\[/tex]
Simplify it,
[tex]r=\dfrac{2}{1}[/tex]
[tex]r=2:1[/tex]
Which is not equal to the given ratio. Thus the option B is incorrect option.
C)The ratio given in the option C is[tex]12:2[/tex]
Let r is the ratio, then it can be written as,
[tex]r=\dfrac{12}{2}\\[/tex]
Simplify it,
[tex]r=\dfrac{6}{1}[/tex]
[tex]r=6:1[/tex]
Which is equal to the given ratio. Thus the option C is correct option.
D) The ratio given in the option D is[tex]15:3[/tex]
Let r is the ratio, then it can be written as,
[tex]r=\dfrac{15}{3}\\[/tex]
Simplify it,
[tex]r=\dfrac{5}{1}[/tex]
[tex]r=5:1[/tex]
Which is not equal to the given ratio. Thus the option D incorrect option.
Hence the ratio which is equivalent to the given ratio are 6:1 and 12:2. Thus the option A and C is the correct option.
