Answer:
85 ones70 fives15 tens2 fiftiesStep-by-step explanation:
Let a, b, c, d represent the numbers of $1, $5, $10, and $50 bills, respectively. The problem statement tells us ...
a +5b +10c +50d = 685 . . . . . total amount of cash
b = 10 +4c . . . . . . . . . . . . the number of fives is 10 more than 4 times tens
a = b+c . . . . . . . . . . . as many ones as fives and tens combined
d = 2 . . . . . . . . . . the register contained 2 fifty-dollar bills
__
Substituting for 'a', then for 'b', we have ...
(b+c) +5b +10c +50d = 685
6(10 +4c) +11c +50d = 685
60 +35c +50d = 685
Substituting d=2 and subtracting 160 gives ...
35c = 525
c = 15
b = 10 +4c = 10 +4(15) = 70
a = b+c = 70 +15 = 85
The register contained ...

determine the discount between the point(-4,2) and the line 4y=3×+6
Answer:
d = 14/5
Step-by-step explanation:
The point (-4,2) means that;
At x = -4, y = 2
Now general form of a linear equation is;
Ax + By + C = 0
We are given;
4y = 3x + 6
Rearranging to the form of a linear equation gives;
3x - 4y + 6 = 0
Thus, A = 3, B = -4 and C = 6
Thus, at point (-4,2), distance between them is;
d = (3(-4) - 4(2) + 6)/√(3² + (-4)²)
d = -14/5
We will take the absolute value.
Thus; d = 14/5

A bottle of water that is 80°F is placed in a cooler full of ice. The temperature of the water decreases by 0.5°F every minute. What is the temperature (in degrees F ) of the water after 512 minutes?
Answer:
I believe the answer is -176º
The temperature of the water after 512 minutes is T = -176°F
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The initial temperature of the water is 80°F, and it decreases by 0.5°F every minute. So, after "n" minutes, the temperature of the water will be:
T = 80 - 0.5n
To find the temperature of the water after 512 minutes, we can substitute n = 512 into the equation:
Temperature after 512 minutes = 80 - ( 0.5 x 512 )
Temperature after 512 minutes = 80 - 256
On simplifying the equation , we get
Temperature after 512 minutes = 80 - 256
Temperature after 512 minutes = -176°F
Hence , the temperature of the water after 512 minutes will be -176°F.

identify which function accurately models the race car's
average distance traveled at any given time during the race.
Line A passes through the points (-3,2) and (-23,54). Line B is parallel to line A and passes through the point (-8,0). Consider
the equation of line B in the form y= a (x + b), where a and b are rational numbers.
Answer:
Line A passes through (-3, 2) and (-23, 54)
slope of line A will be
[tex]m_{A} =\frac{y_{2}-yx_{1} }{x_{2}- x_{1} } = \frac{54-2}{-23+3} = \frac{52}{20}= \frac{13}{5}[/tex]
Equation of line A will be
[tex](y - y_{1}) = m_{A}(x-x_{1} )\\\\(y - 2) = \frac{13}{5}(x -(-3))\\\\(y - 2) = \frac{13}{5}(x +3))\\ \\\\5((y - 2) = 13(x +3))\\\\5y -10 = 13x + 39\\\\5y = 13x + 49[/tex]
Given line B is parallel to line A, So slope of A and B
[tex]m_{A} \cdot m_{B} = 1[/tex]
slope of line B will be
[tex]\frac{13}{5}\cdot m_{B} = 1\\\\m_{B} = \frac{5}{13}[/tex]
Also given line B passes (-8, 0), therefore the equation of line B
[tex](y-y_{B}) = m_{B}(x-x_{B} )\\\\(y - 0) = \frac{5}{13}(x + 8)\\\\y = \frac{5}{13}(x+8)\\\\[/tex]
Therefore,
[tex]a = \frac{5}{13} \ \ and \ b = 8[/tex]

Answer:
DBECA
Step-by-step explanation:
Recall:
Volume of rectangular prism = Length*Width*Height or
V = Base area * Height
✔️Volume of A:
Length = ½ m
Width = ¼ m
Height = ¼ m
Volume of A = L*W*H = ½*¼*¼
= ¹/32 m³
= 0.03125 m³
✔️Volume of B:
Base area = 32 m²
Height = 7.25 m
Volume of B = base area * height
= 32*7.25
= 232 m³
✔️Volume of C:
Length = ½ m
Width = ¼ m
Height = ½ m
Volume of A = L*W*H = ½*¼*½
= ¹/16 m³
= 0.0625 m³
✔️Volume of D:
Length = 8½ m = 8.5 m
Width = 3½ m = 3.5 m
Height = 9¼ m = 9.25
Volume of A = L*W*H = 8.5 * 3.5 * 9.25
= 275.1875 m³ ≈ 275.2 m³
✔️Volume of E:
Base area = 26⅓ m² ≈ 26.33 m²
Height = 5 m
Volume of E = 26.33 * 5
≈ 131.7 m³
Arrange from greatest to the least volume:
D (275.2) > B (232) > E (131.7) > C (0.0625) > A (0.03125)

Answer:
41.16 m³
Step-by-step explanation:
Step 1: Formula.
To find the volume of a triangular prism, multiply the base, length, and height by 1/2.
Step 2: Explain and solve.
[tex]formula: base*length*height*1/2[/tex]
[tex]base = 4.2[/tex]
[tex]length = 7[/tex]
[tex]height=2.8[/tex]
Now, we simply plug the numbers into the formula.
[tex]4.2*7*2.8*1/2 = 41.16m^3[/tex]
Step 3: Conclude.
I, therefore, believe the volume of this triangular prism is 41.16 m³.
Suppose we want to pick two numbers from 1 to 100 randomly . what is the probability that the sum of the two picked numers is divisible by 5
Answer:
1/5 or 0.2
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
Numbers that would be divisible by 5 are multiples of 5
they include = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100
there are 20 numbers
Probability the two numbers would be divisible by 5 = 20/100
To transform to the simplest form. divide both the numerator and the denominator by 20
1/5

Answer:
C. y=3x-6
Step-by-step explanation:
Indicate in standard form the equation of the line passing through the given points.
X(0,6). Y(5,6)
Answer:
y = 6
Step-by-step explanation:
Let the y-intercept form of the equation of the line is,
y = mx + b
Here, m = Slope of the line
b = y-intercept
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the passing through (0, 6) and (5, 6) will be,
m = [tex]\frac{6-6}{0-5}[/tex]
m = 0
Equation of the line with m = 0 will be,
y = 0 + b
y = b
Since, line passes through (0, 6),
By substituting the values in the equation,
b = 6
Therefore, standard equation of the line passing through (0, 6) and (5, 6) will be,
y = 6

A fair die is cast four times. Calculate
the probability of obtaining exactly two
6's.
Round to the nearest tenth of a
percent.
Answer:
0.1319 or 13.2%
Step-by-step explanation:
You can solve this using the binomial probability formula.
The fact that "obtaining at least two 6s" requires you to include cases where you would get three and four 6s as well.
Then, we can set the equation as follows:
P(X≥x) = ∑(k=x to n) C(n k) p^k q^(n-k)
n=4, x=2, k=2
when x=2 (4 2)(1/6)^2(5/6)^4-2 = 0.1157
when x=3 (4 3)(1/6)^3(5/6)^4-3 = 0.0154
when x=4 (4 4)(1/6)^4(5/6)^4-4 = 0.0008
Add them up, and you should get 0.1319 or 13.2% (rounded to the nearest tenth)

Solve for the marked angle.
Answer:
m∠KQR = 69°
Step-by-step explanation:
By the definition of intercepted arc and inscribed angle,
Intercepted arc measures the double of the inscribed angle.
m(arc KS + arc SR) = 2m∠KSR
132° + 90° = 2m∠KSR
m∠KSR = 111°
Since, quadrilateral KQRS is a cyclic quadrilateral,
m∠KSR + m∠KQR = 180°
111° + m∠KQR = 180°
m∠KQR = 180° - 111°
m∠KQR = 69°
m∠KQR = m∠Q = 69°
