Tommy can exchange 8 euros for 11 dollars.At this rate, how many dollars can Tommy get with 12 euros?
Answer:
16.50 dollars
Step-by-step explanation:
We can use proportion
8 euros --- 11 dollars
12 euros --- x dollars
x = 12 * 11/8 = 16.5= 16.50 dollars
Answer:
16.5 dollars
Step-by-step explanation:
Let's make a proportion using the following setup.
dollars/euros=dollars/euros
Tommy can get 11 dollars for 8 euros. We don't know how many dollars he can get with 12 euros. Therefore, we can say that he can get x dollars with 12 euros.
11 dollars/8 euros=x dollars/12 euros
11/8=x/12
We want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
x is being divided by 12. The opposite of division is multiplication. Multiply both sides by 12.
12*(11/8)=(x/12)*12
12*11/8=x
12*1.375=x
16.5=x
Tommy can get $16.50 with 12 euros.

Answer:
D
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here { a, b ] = [ - 1, 2 ], thus
f(b) = 4 ← from (2, 4 )
f(a) = [tex]\frac{1}{2}[/tex] ← from (- 1, [tex]\frac{1}{2}[/tex] ) , thus
average rate of change = [tex]\frac{4-\frac{1}{2} }{2-(-1)}[/tex] = [tex]\frac{\frac{7}{2} }{3}[/tex] = [tex]\frac{7}{6}[/tex] → D

what is 6(1-10p)-7 jfghhdddcv
Answer:
-1 -60p
hope it helps
Step-by-step explanation:
6 (1-10p) -7
First solve 6(1-10p) using distributive property of subtraction
(6*1)-(6*10p) -7
= 6-60p -7
Add the constants of the equation
= (6-7) -60p
= -1 - 60p
Answer:
-60p-1
Step-by-step explanation:
Well in simplyfying it we can determine that 6*1 is 6 and 6*-10p is -60p
So then the answer is -60p-1.
Which ordered pair is the solution to the system of linear equations y = negative 7 x + 2 and y = 9 x minus 14?
Answer:
(1, -5) is the solution of the system
Step-by-step explanation:
y = negative 7 x + 2 should be written as y = -7x + 2, and
y = 9 x minus 14 as y = 9x - 14
Use elimination by substitution to solve this system. Equate the two equations together to eliminate y: y = 9x - 14 = -7x + 2.
Combining like terms, we get 9x - 14 = -7x + 2 => 16x = 16
Dividing both sides by 16 yields x = 1.
Substituting 1 for x in the first equation yields the corresponding y-value:
y = -7(1) + 2 = -5
Thus, the ordered pair (1, -5) is the solution of the system.

Blank
or
Blank
400 ml.
Answer:
The true mean volume of p
aint in each can is greater than or equals to 400ml
Step-by-step explanation:
The symbol of μ represents the mean of a data.
Mean can be defined as the average value of a set of data
Let consider the question.
We know that
μ ≥ 400ml
Where the sign ≥ means "greater than or equals to"
Which means that μ is greater than or equals to 400ml
So the solution is:
1st blank = greater than
2nd blank = equals to

The parent function f(x) = 5 ^ x has been venically compressed by a factor of one-half shifted to the three units and up two units choose the correct function
Answer:
See the explanation
Step-by-step explanation:
The given function is:
f(x) = 5ˣ
Transformation of a parent function is given by the formula:
g(x) = k · f(x + a) + b
Where
k represents vertical compression if |k| < 1 and k represents vertical stretch of |k| > 1
f(x) shifts left by a units if a>0 and f(x) shift right by a units if a<0
f(x) shift up by b units if b>0 and f(x) shifts down by b units if b<0
In the question it is given:
k = 1/2
Shifts right by 3 units ⇒ a = -3
Shift up by 2 units ⇒ b = 2
Substitute in the formula:
g(x) = (1/2) · f(x - 3) + 2
[tex]g(x) = \frac{1}{2}\cdot5^{x-3}+2[/tex]

In the diagram below, points A and B represent two lakes. How far apart are the lakes? 131.5 ft 456.3 ft 474.6 ft 633.9 ft
Answer:
I don't know the answer, but I just took a test and the answers ARE NOT 456.3 and ARE ALSO NOT 474.6
Step-by-step explanation:
The distance between the two lakes = 633.9 ft. So, we take the 4th option.
What is the law of cosines?By the law of cosines, a triangle with sides a, b, and c, and the angle opposite to c being γ,
c = √(a² + b² - 2.a.b.cos γ)
How do we solve the given question?To solve the question, we will use the law of cosines.
Let a = 560 ft., b = 350 ft., c = d (unknown distance).
γ = 160° - 75° = 85°.
We substitute the values in the formula to get,
d = √(560² + 350² - 2(560)(350)(cos 85°)
or, d = √(313600 + 122500 - 392000*0.0871)
or, d = √(436100 - 34165.05116)
or, d = √401934.948842
or, d = 633.983397
So, we take d = 633.9 ft., the 4th option.
∴ The distance between the two lakes = 633.9 ft.
