The gas in Dads car holds 12 gallons. Athe gas tank in Moms truck holds 50% more than that. How much gas does the truck's tank hold? Explain why this situation can be represented by the equation. Make sure that you explain what t represents.
Answer:
18 gallons
Step-by-step explanation:
Step one:
given data
The gas in Dad's car holds 12 gallons
the gas tank in Moms truck holds 50% more than that in Dad's car
Hence 50% of 12 is
=50/100*12
=0.5*12
= 6 gallons
We are told that the gas tank in Moms truck holds 50% more than that in Dad's car
Therefore Mum's car will hold
=12+6
=18 gallons

mPSQ=
312
48
132
Answer:
312°
Step-by-step explanation:
PSQ = 360°- mPAQ
at mPAQ=mSAR
so PSQ =360°-48°=312°
Answer:
Answer:
312°
Step-by-step explanation:
In this it says to find the measure of PSQ
That means the arc starts at P goes through S and ends at Q.
In this case the only section of the circle that is not included is ∠PAQ
∠PAQ is 48° due to reflexive property
Now subtract 48 out of 360
360 - 48 = 312
312° is you answer
Hope this helps

Alisa, Mykia, and Martin decide to share the responsibility of walking their dog every day. There are 365 days in a year. How many days each year does Alisa need to walk the dog?
Answer: 121 2/3 days
Step-by-step explanation:
Number of days in a year = 365 days
Number of friends = 3 friends
The number of days each year that Alisa need to walk the dog will be:
= Number of days in a year / Number of friends.
= 365 / 3
= 121 2/3 days
= 121 days + (2/3 × 24hours)
= 121 days 16 hours
Note that 24 hours = 1 day

Answer:
58°
Step-by-step explanation:
A + B + C = 180 °
The smallest value of C is 91.
A + B = 89
A = 2B - 4
2B - 4 + B = 89
3B - 4 = 89
3B = 93
B = 31
A + 31 = 89
A = 58
Can someone help me? I dont really know how to do this?
Answer:
54
Step-by-step explanation:
x+2x+2x=5x
90/5=18
18*3=54
Answer:
The answer is 54.
Step-by-step explanation:
Ok buddy
‣Remember that a right angle equals 90 degrees.
‣The numbers lie on a right angle.
‣So watchya gonna do is combine the like terms.
[tex]x + 2x + 2x = 5x[/tex]
‣In an equation, that finna look like:
[tex]5x = 90[/tex]
‣Solve that equation
[tex] \frac{5x}{5} = \frac{90}{5} \\ \\ x = 18[/tex]
‣Therefore, the value of x is 18.
‣We trynna find 3x so plug it.
[tex]3x \\ 3(18) \\ 54[/tex]
‣That fr is the answer, 54.

In the diagram below of triangle EFG, H is a midpoint of EF and J is a midpoint
of FG. If mZHJF 10x + 36, and mZEGJ = 6x + 44, what is the measure
of ZHJF?
F
H
J
E
G
Answer:
m<HJF = [tex]56^{o}[/tex]
Step-by-step explanation:
From the given diagram, ΔFHJ is similar to ΔFEG. So that;
m<HJF = m<EGJ
⇒ 10x + 36 = 6x + 44
10x - 6x = -36 + 44
4x = 8
x = [tex]\frac{8}{4}[/tex]
x = 2
Substitute the value of x in the expression for m<HJF to have,
m<HJF = 10x + 36
= 10(2) + 36
= 20 + 36
m<HJF = [tex]56^{o}[/tex]
The measure of angle HJF is [tex]56^{o}[/tex].
