Emily looks at a picture. A car in this picture is 30cm long. the scale of the drawing is 1:14
Answer:
Step-by-step explanation:
30 cm:
1: 14
so 1*14 = 14
so 30*14=420
so if you are trying to figure out how long it is in real life it's supposed to be 420 something.
The length of the car in real life is 420 cm or 4.2 meters.
What is Multiplication?Multiplication is a method of finding the product of two or more numbers
If the scale of the drawing is 1:14, this means that every 1 unit on the drawing represents 14 units in real life.
Since the car in the drawing is 30cm long, we can use this to figure out its length in real life units. Let's call the real life length of the car "x".
Using the scale, we can set up the following proportion:
1 / 14 = 30 / x
To solve for x, we can cross-multiply
x = 14 × 30
x = 420
Therefore, the length of the car in real life is 420 cm or 4.2 meters.

2. How many more minutes will it take for the tank drain completely? Explain or show your reasoning.
3. How many minutes before Jaila arrived was the water tank completely full? Explain or show your reasoning.
Answer:
Look below
Step-by-step explanation:
1)= -2/3 per minute decrease by 2 gallons in 3 minutes
2) 5 gallons and lose 2/3 gallons per minute
2/3 gal/minute minutes) = 5 gallons
x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons
3) 10 gallons when full
That is 3 gallons more than the 7 gals there when Jada arrived.
(2/3)(x) = 3
x = 3(3/2) = 9/2 = 4 1/2 minutes
Full= 4 1/2 minutes before she arrived

Terrell wrote that 5 – 4.2 = 8. Which statement about his answer is true? CLEAR CHECK 8 is wrong because a number gets smaller, not larger, when you take 4.2 from it. 8 is right because 50 – 42 = 8. 8 is right because 4.2 + 8 = 5. 8 is wrong because you cannot subtract a decimal from a whole number.
Answer:
a) is wrong because a number gets smaller, not larger, when you take 4.2 from it
Step-by-step explanation:
Given
[tex]5 - 4.2 = 8[/tex]
Required
Determine which of the options is true
First, we need to solve for 5 - 4.2
[tex]5 - 4.2 = 0.8[/tex]
Compare this answer with Terell's answer (8)
We observe that: [tex]0.8 \neq 8[/tex]
This implies that; Terell is wrong
The two options that support the answer being wrong are (a) & (d)
Analyzing (a):
5 should get smaller when 4.2 is subtracted from it.
This isn't the case in Terell's solution.
Hence, (a) is true
Analyzing (d):
d is wrong because a decimal can be subtracted from a whole number
Hence, (a) answers the question

Find the equation of the line that is parallel to y = -7x + 2 and contains the point (-5,32)
Answer:
Y=-7x-3
Step-by-step explanation:
Answer:
y = - 7x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 7x + 2 ← is in slope- intercept form
with slope m = - 7
Parallel lines have equal slopes, thus
y = - 7x + c ← is the partial equation
To find c substitute (- 5, 32) into the partial equation
32 = 35 + c ⇒ c = 32 - 35 = - 3
y = - 7x - 3 ← equation of parallel line
What’s the value of x
Answer:
16
Step-by-step explanation:
This is due to the rule that all shapes exterior angles add to 360.
Therefore 360 = 46 + 3x +62 + 4x + 47 + (180-83)
360 = 248 + 7x
7x = 112
x= 16
