Step-by-step explanation:
A hobby shop sells small and large toy cars. A small toy car is $5.50, and a large toy car is $9. What is an equation that relates the cost, Cin dollars
with the number of small toy cars, S, and the number of large cars, L. purchased?
Answer:
C = 5.50S + 9L
.............
The equation that relates the cost, Cin dollars with the number of small toy cars, S, and the number of large cars, L is C = 5.50S + 9L.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A hobby shop sells small and large toy cars. A small toy car is $5.50, and a large toy car is $9.
Let S be the number of a small toy car and L be the number of a large toy car.
The equation can be made:
Total cost:
C = 5.50S + 9L
Thus, the equation that relates the cost, Cin dollars with the number of small toy cars, S, and the number of large cars, L is C = 5.50S + 9L.

Solve the equation: 25^2n+1=625
Answer:
The value of n is 1/2.
Step-by-step explanation:
[tex] {25}^{2n + 1} = 625[/tex]
[tex] log_{25}(625) = 2n + 1[/tex]
[tex]2 = 2n + 1[/tex]
[tex]2n = 1[/tex]
[tex]n = \frac{1}{2} [/tex]
The solution for the given equation is n=624/625.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 25²n+1=625.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 625n+1=625

what is the value of f
Answer:
f = 22
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
140° is an exterior angle of the triangle, thus
4f + 1 + 51 = 140, that is
4f + 52 = 140 ( subtract 52 from both sides )
4f = 88 ( divide both sides by 4 )
f = 22

HELP 66 hundreds÷10 Choose 1 answer: (Choice A) A 66 \text { thousands}66 thousands66, start text, space, t, h, o, u, s, a, n, d, s, end text (Choice B) B 66 \text { ones}66 ones66, start text, space, o, n, e, s, end text (Choice C) C 66 \text { tens}66 tens
Answer:
66 tens
Step-by-step explanation:
Required
Solve 66 hundreds / 10
First, we need to express 66 hundreds as a number.
1 hundred = 100
66 hundreds = 66 * 1 hundred
So:
66 hundreds = 66 * 100
66 hundreds = 6600
66 hundreds / 10 would then be calculated as:
66 hundreds / 10 = 6600/10
66 hundreds / 10 = 660
660 can be represented as:
66 hundreds / 10 = 66 * 10
or
66 hundreds / 10 = 66 tens

5) Arun had Rs 965.27 in the bank. He withdrew Rs 209.98. What amount of money is left in the bank?
Given that:
Arun's capital = Rs 965.27 in bank
and he made a withdrawal of Rs 209.98.
The amount left in bank = Rs 965.27 - Rs 209.98
The amount left in bank = Rs 755.29
6) Sachin's weight was 52.8 kg before he became ill. In the first week, he lost 2.9 kg but in the second week, he gained 0.72kg. What was his total weight at the end of the second week?
Initial weight = 52.8 kg
After he became ill:
During the first week, he lost 2.9 kg
He gained 0.72 kg in the second week.
His total weight after the second week = (52.8 - 2.9 + 0.72) kg
His total weight after the second week = 50.62 kg
7) The height of Akash is 1.26m and that of Arjun is 1.3m , who is taller and by how much?
Given that:
The height of Akash = 1.26 m; &
The height of Arjun = 1.3 m.
The Arjun is taller than Akash and he is taller by :
1.3 m - 1.26 m = 0.04 m
Arjun is taller than Akash and he is taller by 0.04 m

can you show your work for this 4m-5(3m+10)=126
Answer:
m=−16
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4m−5(3m+10)=126
4m+(−5)(3m)+(−5)(10)=126(Distribute)
4m+−15m+−50=126
(4m+−15m)+(−50)=126(Combine Like Terms)
−11m+−50=126
−11m−50=126
Step 2: Add 50 to both sides.
−11m−50+50=126+50
−11m=176
Step 3: Divide both sides by -11.
−11m /−11 = 176 /−11
m=−16

From A to B a private plane flies 2.8 hours at 110 mph on a bearing of 64 degrees . It turns at point B and continues another 1.7 hours at the same speed, but on a bearing of 154 degrees to point C. Round each answer to three decimal places. a. At the end of this time, how far is the plane from its starting point? b. On what bearing is the plane from its original location?
Answer:
a. 360.323 m
b. [tex]95.265^{o}[/tex]
Step-by-step explanation:
Distance covered from A to B = speed x time
= 110 x 2.8
= 308 m
Distance covered from B to C = speed x time
= 110 x 1.7
= 187 m
The sum of angles at B = [tex]64^{o}[/tex] + [tex]26^{o}[/tex]
= [tex]90^{o}[/tex]
a. The distance of the plane from it starting point to C can be determined by applying the cosine rule.
[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] - 2ac Cos B
Sot hat;
[tex]b^{2}[/tex] = [tex]187^{2}[/tex] + [tex]308^{2}[/tex] - 2(187 x 308) Cos [tex]90^{o}[/tex]
But, Cos [tex]90^{o}[/tex] = 0
So that,
[tex]b^{2}[/tex] = [tex]187^{2}[/tex] + [tex]308^{2}[/tex]
= 34969 + 94864
= 129833
b = [tex]\sqrt{129833}[/tex]
= 360.323
The distance from A to C is 360.323 m.
b. Applying the sine rule;
[tex]\frac{a}{SinA}[/tex] = [tex]\frac{b}{SinB}[/tex]
[tex]\frac{187}{SinA}[/tex] = [tex]\frac{360.323}{Sin90^{o} }[/tex]
[tex]\frac{187}{SinA}[/tex] = [tex]\frac{360.323}{1}[/tex]
Sin A = [tex]\frac{187}{360.323}[/tex]
= 0.5190
⇒ A = [tex]Sin^{-1}[/tex] 0.5190
= [tex]31.265^{o}[/tex]
The bearing of the plane from its original location = [tex]64^{o}[/tex] + [tex]31.265^{o}[/tex]
= [tex]95.265^{o}[/tex]
Using the Sine and Cosine rule on the triangle generated using the information given, the distance and bearing of the plane from its original location are :
360.32 mile 95.26°Using the Cosine Rule :
b² = a² + c² - 2abCosBb² = 187² + 308² - 2(187)(308)Cos(90°)
b² = 187² + 308² - 0
b² = 129833
b = √129833
b = 360.32 miles
B.)
Using the Sine rule :
a/sinA = b/SinB = c/SinC
187/sinA = 360.32/sin90
187/sinA = 360.32/1
sinA × 360.32 = 187
sinA = 187 / 360.32
sinA = 0.51898
A = Sin¯¹(0.51898)
A = 31.264
Hence, bearing of C from A = (64° + 31.264) = 95.26°
