Answer:
<h3>
1.50X+2.50Y=25</h3><h3>
&</h3><h3>
X+Y=6 are required systems</h3>
(Solution: X=16 and Y=-10)
<u>Explanation:</u>
》Total money that will be spent on flour and corn meal altogether(T)
=$25
》Since it is not mentioned that whether corn and flour are bought in same quantity or not, we will assume them of different quantity.
i.e.,Suppose
》<u>X pound </u>of <u>flour</u> is bought
&
》<u>Y pound </u>of <u>corn</u> is bought.
So,
》Cost of flour(F)=$1.50X
》Cost of corn(C)=$2.50Y
So total cost will be sum of cost of flour and corn altogether,
Writing it in equation(linear),
<u>F+C=T</u>
<h3>
<u>1.50X+2.50Y=25</u></h3>
Also,
Total pounds=6
ie,
<h3>
<u>X+Y=6</u></h3>
Answer:-12/5
Step-by-step explanation:
1 km = 1000 m
400 km = 400·1000 m = 400000 m
and
1 h = 3600 s
4 h = 4·3600 s = 14400 s
so the average speed:
Answer:
m∠CAO=8º
m∠SAC=82º
Step-by-step explanation:
We know that m∠OAS is 90º because it is a radius to a tangent. This will be useful later.
OA=OB because they are both radii. If we draw a line from A to B, this makes an isosceles triangle ABO with a vertex angle of 32 because of the central angle theorem. This means that m∠OAB and m∠OBA are both 74º.
Isosceles triangle CAB is also formed with the construction of AB. Using the inscribed angle theorem, we can find ACB, which is 16º. Solve for the other angles and you get 82º. To find m∠CAO, subtract m∠OAB from m∠CAB, and this returns 8.
To find m∠SAC, subtract m∠CAO from m∠OAS, which is 90º-8º, and you get 82º.
