Answer:
she has 3 quarters
Step-by-step explanation:
let's call the amount of dimes D
let's call the amount of quarters Q
you know that she has 11 coins in total,
so D + Q = 11.
you also know that each dime is worth 10 cents.
and each quarter is worth 25 cents.
so 10d + 25q = 155
this is a system of equations. solve by substitution:
d = 11 - q
10d + 25q = 155
10(11 - q) + 25q = 155
110 - 10q + 25q = 155
15q + 110 = 155
15q = 45
q = 45/15
q = 3

A skier is on the top of a 350 meter tall mountain looking down at a tree. The direct path from the tree to the skier is 505 meters. What is the angle of depression from where the skier is standing to the base of the tree
Answer:
[tex]43.87^{\circ}[/tex]
Step-by-step explanation:
We are given that
Height of mountain=350 m
Distance from the tree to the skier=505 m
We have to find the angle of depression from where the skier is standing to the base of the tree.
In triangle ABC
[tex]\frac{AB}{AC}=sin\theta[/tex]
By using the formula
[tex]\frac{Perpendicular\;side}{Hypotenuse}=sin\theta[/tex]
[tex]\frac{350}{505}=sin\theta[/tex]
[tex]sin^{-1}(\frac{350}{505})=\theta[/tex]
[tex]\theta=43.87^{\circ}[/tex]
Hence, the angle of depression from where the skier is standing to the base of the tree=[tex]43.87^{\circ}[/tex]
TJ makes a salary of $400 a week. He also
makes a commission of 15% off of
everything he sells for the week. If his total
sales are $15,000, what is his total pay for
the week?
Answer:
Step-by-step explanation:
If TJ made 15,000 dollars in a week, with the 15% commission,
15,000*15/100=2,250 in commission
2250+400=2650 salary for that week

5x -7 + 2x = 4x + 5
Answer:
x = 4
Step-by-step explanation:
5x -7 + 2x = 4x + 5
Combine like terms
5x + 2x -7 = 4x + 5
7x - 7 = 4x + 5
Combine like terms again
-4x + 7x - 7 = 4x - 4x + 5
3x - 7 = 5
3x = 5 + 7
3x = 12
Divide by 3 both sides
3x/3 = 12/3
x = 4

HELP ASAP Name an angle supplementary to angle5
Answer:
Angle 1
Step-by-step explanation:
The angle supplementary to 5 is 1 because two angles are supplementary when they add up to 180 degrees.
So therefore, on the other/opposite side of angle 5 is angle 1.
The supplementary angle to ∠5 is D. ∠6 as the sum of this two angles is 180°.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know two angles are supplementary if the sum of their measure is 180°.
Now, From the given diagram we can conclude that a straight line is forming with ∠5 and ∠6, So the sum of these angles must be 180° hence supplementary.
Therefore, The angle supplementary to ∠5 is ∠6.

If 6x – 10y
9 is a true equation, what would be the value of -18x + 30y?
Answer:
The value of -18x + 30y is -27
Step-by-step explanation:
Algebraic Expressions
It's given that:
6x - 10y = 9
We are required to find the value of
-18x + 30y
The easiest way to solve the problem is to visualize that:
-18x = -3(6x)
30y = -3(-10y)
This means that the second expression is equal to the first expression multiplied by -3, thus:
-18x + 30y = -3(6x - 10y) = -3*9 = -27
The value of -18x + 30y is -27
