Answer:
Step-by-step explanation:
The jar contains 2 types of coins dimes and quarters
the total amount is equal to 36.25 dollars
the total number of coins is 250
let number of dimes be x and quarters be y
let us put the equation
0.10x + 0.25y = 36.25
for our convinience convert all money to cents i.e. = 3625 cents
now the equations are
10x + 25y = 3625
x + y = 250
we need to solve for y i.e. number of quaters
y = 250 - x
rewrite the equation substituting y in x place
10(250 - y) +25 y = 3625
2500 - 10y +25y = 3625
15y = 1125
y = 75
so the number of quarters = 75
cross checking :
number of dimes = 250 - 75 = 175
total = 10x175 + 25x75 = 1750 + 1875 = 3625 = $36.25

A) 5t - 6= 3 - 41
Me ajuda!!!! Por favor
Answer:
t= -32/5
Step-by-step explanation:
1. Simplify 3-41= -38 5t-6 = -38
2. Add 6 to both sides 5t= -38+6
3. Simplify -38+6=-32 5t= -32
4. Divide both sides by 5 and it should give you t = − 32/5
If you want to check your answer 1. 5t-6 = 3-41 let t = -32/5 5× -32/5 -6 = 3-41
2. Cancel 5 -32 -6 = 3-41
3. Simplify -32-6= -38 -38= 3-41
4. Simplify 3-41= -38
-38=-38 and that how you check your answer to see it was right.

Harold is moving a 5- foot tall refrigerator. He tilts it onto its rear edge forming an angle between the back of the refrigerator and the floor; the top edge of the tilted refrigerator is exactly 4 feet above the floor as shown in the following diagram.
What is the cosine of the angle the refrigerator makes with the floor?
A, 4/5
B, 5/4
C, 4/3
D, 3/4
E, 3/5
Please help I’ll give branliest
The cosine of the angle the refrigerator makes with the floor is option (E) 3/5 is the correct answer.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
Harold tilted the 5 foot fridge, so the slanting height = 5 feet
The tilted refrigerator makes the height 4 feet from the floor.
From the diagram,
The three sides of the triangle according to Pythagoras theorem are
Hypotenuse side, h = 5 feet
Opposite side, o = 4 feet
Let a be the adjacent side.
By Pythagoras theorem,
[tex]Hypotenuse^{2} = Opposite^{2}+Adjacent^{2}[/tex]
⇒ [tex]5^{2} =4^{2} +a^{2}[/tex]
⇒ [tex]a^{2} = 25-16[/tex]
⇒ [tex]a=\sqrt{9}[/tex]
⇒ [tex]a=3[/tex]
Thus the trigonometric ratio cosine of the angle is
[tex]cos \theta =\frac{Adjacent}{Hypotenuse}[/tex]
⇒ [tex]cos \theta =\frac{3}{5}[/tex]
Hence we can conclude that the cosine of the angle the refrigerator makes with the floor is option (E) 3/5 is the correct answer.

Two functions are shown below
f(x)=8x+10
g(x)=6x-4
What is f(4)-g(3)?
Answer:
c.28
Step-by-step explanation:
Given
f(x) = 8x + 10 and g(x) = 6x - 4
f(4) = 8*4 + 10
= 32 + 10
= 42
g(3) = 6 * 3 - 4
= 18 - 4
= 14
Now
f(4) - g(3)
= 42 - 14
=28

Admission to the fair is $15 each ride cost $3 micah spent a total of $36 he spent all of his money on rides and admission
Answer:
7
Step-by-step explanation:
Admission cost = $15
Cost per ride = $3
Total amount spent = $36
We can obtain the number of rides thus :
Let number of rides = x
Admission cost + (cost per ride * number of rides) = total amount spent
15 + 3x = 36
3x = 36 - 15
3x = 21
x = 21 / 3
x = 7
Number of rides = 7

Step-by-step explanation:
dn means the difference (meaning what do you add/subtract to get the next number)
T0 means the term before the first one you got.
Tn = dn + T0
Tn = 2n + 0
Therefore our equation will be
Tn = 2n

A sport store pays its wholesaler $40 for a baseball bat, and then sells it to a customer for $76. What is the markup rate?
Answer:
Markup 90%
Step-by-step explanation:
If $40 is 100% of the price
then
$76 is ..........x
Cross multiplication
40(x) = 76(100)
40x = 7600
Divide by 100
x = 190
190% = 100% + 90%
That means that the price is the whole price(100%) plus 90%
so the markup is 90%
ANOTHER WAY:
The difference in prices is $76-$40=$36. So, we need to find what percentage of 40 is 36.
We do this by dividing: 36/40=0.9, which is 90%. So, the markup is 90%.
