Answer:
Number of nickels = 17
Number of dimes = 23
Step-by-step explanation:
Let
x = number of nickels
y = number of dimes
x + y = 40 (1)
0.05x + 0.10y = 3.15 (2)
From (1)
x = 40 - y
Substitute x = 40 - y into (2)
0.05x + 0.10y = 3.15 (2)
0.05(40 - y) + 0.10y = 3.15
2 - 0.05y + 0.10y = 3.15
- 0.05y + 0.10y = 3.15 - 2
0.05y = 1.15
y = 1.15/0.05
y = 23
Substitute y = 23 into (1)
x + y = 40 (1)
x + 23 = 40
x = 40 - 23
x = 17
Number of nickels = 17
Number of dimes = 23

What is a quadrilateral?Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral.
We are given that Quadrilateral ABCD is rotated 90° clockwise about the origin.
A(-5,5) B (1,5 ) C(4, 12) D (5, 1)
Consider the point be having coordinates (x,y).
If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
The coordinates of quadrilateral A'B'C'D are follows as;
A’(5,-5),B’(1,-5),C’(1,-2)
So, the correct option is A

The third side of a triangle can be any value in the range of -
1 ≤ a < 17.
What is a triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique planeGiven are two sides of a triangle as b = 7m and c = 10m.
The sum of two sides of a triangle is always greater than the third side. Mathematically -
a < {b + c}
a < {7 + 10}
a < 17
a ∈ [1, 16]
Therefore, the third side of a triangle can be any value in the range of -

priced p dollars after a markdown of 30%?
a.) s=0.3p
b.) s=0.7p
c.) p=0.35
d.) p=0.75
Answer:
0.70p
Step-by-step explanation:
"30% off" means paying only 70% of the original sales price (subtracting 30% from 100% yields 70%). Next, find the decimal equivalent of 70%:
It is 0.70. Finally, multiply the price p by 0.70: 0.70p (Answer b)

Mrs. Smith charges $30 per hour for tutoring
services plus a one time fee of $10 for supplies.
How many tutoring sessions can a student attend
if the parent will spend, at most, $2,500?
Answer:
62.5
Step-by-step explanation:
$30 per hour + one time fee of $10= 40$ in total.
[tex] \frac{2500}{40} = 62.5[/tex]
Answer:
83 hours of tutoring, I think.
Step-by-step explanation:
If there is a total of 2,500 dollars to spend, you have to subtract the 10 dollar fee from it first to get 2,490 dollars. Then, you divide that by 30 dollars to get the total amount of hours which is 83.
Marcus baked a loaf of banana bread for a party. He cut the loaf into equal size pieces. At the end of the party, there were 6 pieces left. If Marcus told you that 1 4 of the loaf was left, how can you find the number of pieces that were in the whole loaf? Complete the explanation. The denominator in 1 4 is , so I will draw circles to show the equal parts. Since pieces are 1 4 of the loaf, I will draw counters in each circle. By multiplying the number of equal parts by the number of counters in each equal part, I know that there were equal size pieces in the whole loaf.
Answer:
6*4 = 24
Step-by-step explanation:
Hopefully that helps, and you can write fractions as x/y.
Answer:

I know that probably looks like a jumbled mess huh .. the formula
In words it's basically saying.. get the distance between the two points and take half of that
S = (10, -1) where it takes the form of (x1,y1)
T = (2, -7 ) where it takes the form of (x2,y2)

43 lbs of bananas cost $86. How many
lbs of bananas can you get with $100 ?
will get brainliest
Answer:
$200
Step-by-step explanation:
Hey There!
So first we want to find the price of each pound of banana
To do this we divide the cost by amount of bananas bought
86/43=2
so each pound of bananas cost $2
now we just multiply 2 and 100
2x100=200
so 100 pounds of bananas would cost $200
hope this helps :)
Answer:
50
Step-by-step explanation:
Calculate how much 1lbs of bananas cost by dividing 86 by 43. getting you 2. That means each lbs of bananas is $2. Then divide $100 by $2 getting you 50 because you have $100. So you can get 50lbs of bananas with $100.

Step-by-step explanation:
The exterior of a triangle is the sum of two of its interior angles except the one adjacent to it. The angle x is evaluated as 135°.
What is a triangle?A triangle is a two dimensional shape bounded by three sides. The sum of the interior angles of a triangle is 180°. The longest side of a triangle is always less than the sum of other two sides.
Given that,
There is a triangle shown in the figure with following angles,
∠y = 102° and ∠Z = 57°.
Angle x is the exterior angle of the given triangle. Use the property of exterior angle to get,
∠x = ∠B + ∠Z
= (180° - y) + 57°
= (180° - 102°) + 57°
= 135°
Hence, the angle x has been worked out as ∠x = 135°.
