b+g=708
15b+10g=8640
Answer:
b=312
g=396
you can use substitution or elimination
Step-by-step explanation:
(b+g=708)10
(15b+10g=8640)1
(10b+10g=7080)-
(15b+10g=8640)
10b-15b=-1560
-5b=-1560
divide both sides by -5
b=312
then substitute
b+g=708
312+g=708
g=708-312
g=396
so b=312
g=396

 Find sin2x, cos2x, and tan2x if sinx=-15/17 and x terminates in quadrant III
Given:
[tex]\sin x=-\dfrac{15}{17}[/tex]
x lies in the III quadrant.
To find:
The values of [tex]\sin 2x, \cos 2x, \tan 2x [/tex].
Solution:
It is given that x lies in the III quadrant. It means only tan and cot are positive and others are negative.
We know that,
[tex]\sin^2 x+\cos^2 x=1[/tex]
[tex](-\dfrac{15}{17})^2+\cos^2 x=1[/tex]
[tex]\cos^2 x=1-\dfrac{225}{289}[/tex]
[tex]\cos x=\pm\sqrt{\dfrac{289-225}{289}}[/tex]
x lies in the III quadrant. So,
[tex]\cos x=-\sqrt{\dfrac{64}{289}}[/tex]
[tex]\cos x=-\dfrac{8}{17}[/tex]
Now,
[tex]\sin 2x=2\sin x\cos x[/tex]
[tex]\sin 2x=2\times (-\dfrac{15}{17})\times (-\dfrac{8}{17})[/tex]
[tex]\sin 2x=-\dfrac{240}{289}[/tex]
We know that,
[tex]\cos 2x=1-2\sin^2x[/tex]
[tex]\cos 2x=1-2(-\dfrac{15}{17})^2[/tex]
[tex]\cos 2x=1-2(\dfrac{225}{289})[/tex]
[tex]\cos 2x=\dfrac{289-450}{289}[/tex]
[tex]\cos 2x=-\dfrac{161}{289}[/tex]
Using the trigonometric ratios, we get
[tex]\tan 2x=\dfrac{\sin 2x}{\cos 2x}[/tex]
[tex]\tan 2x=\dfrac{-\dfrac{240}{289}}{-\dfrac{161}{289}}[/tex]
[tex]\tan 2x=\dfrac{240}{161}[/tex]
Hence, the required values are [tex]\sin 2x=-\dfrac{240}{289},\cos 2x=-\dfrac{161}{289},\tan 2x=\dfrac{240}{161}[/tex].

A computer store changed the price of a laptop. It was originally $900, but now it is $1,100.Find the percent of change
Answer:
The percent of change is 22.22%.
Step-by-step explanation:
You can calculate the percent of change by subtracting the original number from the final number and dividing that by the original number. Then, you have to multiply the result for 100:
percent of change=((1,100-900)/900)*100
percent of change=(200/900)*100
percent of change=22.22%
According to this, the answer is that the percent of change is 22.22%.

The sum of the speeds of two trains is 724.3 miles per hour. If the speed of the first train is 11.7 mph faster than that of the second train, find the speeds of each.
Answer:
A=368 miles
B= 356.3 miles
Step-by-step explanation:
Given data
Let the two trains be A and B
A+B=724.3----------1
A-B=11.7--------------2
From eqn 1
A= 724.3-B
put this in place of A in eqn 2
724.3-B-B= 11.7
724.3-2B= 11.7
724.3-11.7= 2B
712.6=2B
B= 712.6/2
B= 356.3 miles
Put B=356.3 in eqn 1
A+356.3=724.3----------1
A= 724.3-356.3
A=368 miles
A brick of lead weighs 6,328 grams and has the following dimensions: length of 20 cm, height
of 8 crn, and width of 35 mm. What is the approximate density of the lead? Round to the
nearest tenth
Answer:
11.3
Step-by-step explanation:
Volume: L * W * H
L = 20
W = 8
H = 35 mm = 35/10 = 3.5 cm
V = 20 * 8 * 3.5
V = 560 cm^3
Density = m/v
Density = 6328 / 560
Density = 11.3

P is a function that gives the cost, in dollars, of mailing a letter from the United States to
Mexico in 2018 based on the weight of the letter in ounces, w.
1. How much does it cost to send a letter
that weighs 1.5 ounces? 2 ounces?
2. Sketch a graph of the function on the
coordinate plane
postage (dollars)
Answer:
1: 1.5 would be 1.72 and 2 would also be 1.72.
2: Draw points at (0,1.15) (1, 1.72) (2, 2.29) (3, 2.86) Flatline Connections
Step-by-step explanation:
If Im reading it right you take 1.5 ounces and plug it into the function (it would be between 1 and 2) it would spit out 1.72 (which I'm assuming is the postage)
It will cost
(i) $1.72 if weight is 1.5 ounces,to send a letter.
(ii)$1.72 if weight is 2 ounces, to send a letter.
first, let us find a relation between postage(dollars) and weight(ounces)
this is an equation of a straight line passing through (0,1.5) and (2,0).
y=mx+c
[tex]P(w)=\frac{1.5-0}{0-2} x + c\\\\P(w)=-0.75x+c\\\\[/tex]
since it passes through (2,0) it will satisfy the equation
therefore, c =1.5
the equation will be: [tex]P(w)=-0.75w+1.5[/tex]
after we merge both the relations, we find a single relation between cost and weight
since the cost value is 1.72 in 1 <w [tex]\leq[/tex]2
if weight is 1.5 ounces it is clearly $1.72
if weight is 2 ounces it is clearly $1.72
therefore, it will cost
(i) $1.72 if weight is 1.5 ounces,to send a letter.
(ii)$1.72 if weight is 2 ounces, to send a letter.

The ratio of nonfiction books to fiction books on a shelf is 5:3. There are 12 fiction
books on the shelf. How many books are on the shelf?
Answer:

Step-by-step explanation:
the ratio is 5:3 the you divide the 12 fiction by 3 you get 4 so if the fiction is 4 then you times it by 5 and you get 20
The ratio of fiction books to nonfiction books on the shelf is 5:3, if there are 12 fiction books are on the shelf, then total number of books on the self, 32
What is the ratio?A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.
Given that,
The ratio of nonfiction books to fiction books on a shelf is 5:3

Which statements are true about the x-intercepts of quadratic functions?
All quadratic functions have exactly one x-intercept.
An x-intercept is located at the point on the function where the value of x is 0.
A quadratic function can have up to two x-intercepts.
An x-intercept of a quadratic function is also called a zero of the function.
If x = 0 is an x-intercept of a quadratic function, then (x + a) is a factor of the function.
Answer:
Step-by-step explanation:
The following statements are true:
1. A quadratic function can have up to two x-intercepts.
2. An x-intercept of a quadratic function is also called a zero of the function
Write the point-slope form of an equation of the line through the points (-2, -3) and (-7, 4).
A. y+2=−75(x+3)
B. y−4=−75(x−7)
C. y+3=−75(x+2)
D. y+7=−75(x−4)
Answer:
458435464546484845kdnh
Answer:
C. y+3=−7/5(x+2)
Step-by-step explanation:
Line is passing through the points (-2, -3) and (-7, 4).
Slope of line = (-3 - 4)/[-2-(-7)]= (-7)/(-2+7) = - 7/5
Equation of line in the point-slope form is given as with point (-2, -3).
y - (-3) = - 7/5[x - (-2)]
y + 3 = - 7/5(x +2)
timothy is planting a garden. Tulips cost $125 per bub. The total cost c of his gardening supplies is $1.25 per bub b plus $10 for a bag of mulch. What is the independent and dependent variables and the equation and solution!
Answer:
Independent variable = number of bub (b)
Dependent variable = total cost (c)
Equation: c = $1.25b + $10
Timothy would spend: $20
Step-by-step explanation:
Total cost = c
Number of bub = b
✔️Total cost, c, is dependent on the number of bub, b.
Therefore:
Independent variable = number of bub (b)
Dependent variable = total cost (c)
✔️Equation that describes this situation can be written as:
c = $1.25b + $10
✔️If Timorhy buys 8 bubs, he would spend the following:
Substitute b = 8 into c = $1.25b + $10, and solve for c.
c = $1.25(8) + $10
c = $10 + $10
c = $20

If f(x) = x2 and g(x) = 3x + 1, then g(f(2))= ?
Answer:
The value of g[f(2)] = 13
Step-by-step explanation:
Given functions:
f(x) = x²
g(x) = 3x + 1
Find:
The value of g[f(2)]
Computation:
f(x) = x²
By putting x = 2 in f(x)
f(x) = x²
f(2) = 2²
f(2) = 2 × 2
f(2) = 4
So the value of f(2) = 4
Value of f(2) putting in g(x)
g(x) = 3x + 1
g(x) = 3x + 1
g[f(2)] = 3[f(2)] + 1
We know that f(2) = 4
So,
g[f(2)] = 3[f(2)] + 1
g[f(2)] = 3[4] + 1
g[f(2)] = 12 + 1
g[f(2)] = 13
The value of g[f(2)] = 13
