Answer:
9 1/6
Step-by-step explanation:
Add the whole numbers: 5+8
Combine the fractions by making their denominator the same: 7/6
Add 6/6 = 1 so add to the whole numbers to make this a mixed fraction.
Answer:
9 1/6
Step-by-step explanation:
5 2/3 + 3 1/2 =
We need to get a common denominator of 6
5 2/3 *2/2 = 5 4/6
3 1/2 *3/3 = 3 3/6
5 4/6 + 3 3/6
8 7/6
8+ 6/6 + 1/6

Daisy walked two-fifths of a mile in one-fifth of an hour. Walking at the same pace, how far will Daisy walk in 1 hour?
Answer:
2 miles
Step-by-step explanation:
2/5 mile = 1/5 hour
x mile(s) = 1 hour
Cross multiplying.
x · 1/5 = 2/5 · 1
x/5 = 2/5
Multiplying both sides by 5.
x = 10/5
x = 2
Daisy will walk 2 miles in 1 hour.
Answer:
[tex]\Huge \boxed{\mathrm{2 \ miles}}[/tex]
Step-by-step explanation:
2/5 mile = 1/5 hour
x mile(s) = 1 hour
Cross multiplying.
x · 1/5 = 2/5 · 1
x/5 = 2/5
Multiplying both sides by 5.
x = 10/5
x = 2

In a recent year, 26.2% of all registered doctors were female. If there were 45,300 female registered doctors that year, what was the total number of registered doctors? Round your answer to the nearest whole number.
Answer:
798980 doctors
Step-by-step explanation:
In a recent year, 26.2% of all registered doctors were female. The total number of registered doctors is 172900.
What is the percentage?The percentage is a quantifiable way of comparing amounts with different totals. Because the percent is an equivalent fraction of the part with the whole, it is also a good way to get unknown amounts.
Percentages are basically fractions with a denominator of 100. We use the percent symbol (%) beside a number to indicate that it is a percentage. To calculate the percentage, divide the value by the total value and multiply the result by 100.
As given, 26.2% of all registered doctors are females.
Consider, the total number of registered doctors as x
26.2% of x are females
26.2% of x is 45,300
26.2 / 100 × x = 45,300
x = 45,300 × 100 / 26.2
x = 172900.76
Therefore, the total number of registered doctors is 172900.

Do the phrases 6 less a number y and 6 less than a number y mean the same thing? Explain. A. No, they do not both mean the same thing. 6 less a number y can be represented by the expression 6 - y. 6 less than a number y can be represented by the expression y - 6. B. Yes, they both mean the same thing. They can also both be represented by the expression y - 6.
Answer:
B. Yes, they both mean the same thing. They can also both be represented by the expression y - 6.
Step-by-step explanation:
Given
Phrase 1: 6 less a number y
Phrase 2: 6 less than a number y
Mathematically,
Phrase 1 can be represented as follows;
[tex]y - 6[/tex]
Mathematically,
Phrase 2 can be represented as follows;

calculate the max shear of cantilever balcony 2m wide 0.2m deep and 1.5m length.
Answer:
14.4 kN
Step-by-step explanation:
cantilever balcony 2m wide 0.2m deep and 1.5m length.
= 2 x 0.2 x 1.5
= 0.6 m³
weight of the balcony
= 0.6 x 24
= 14.4 kN.
therefore the max shear 14.4 kN and is acting at support.
5! The office needs cabinets. The price for the first type of cabinet is $10, it
needs 6 ft2 of floor space, and it has a storage volume of 8 ft. The price
for the second type of cabinet is $20, it needs 8 ft? of floor space, and it
has a storage volume of 12 ft. The company wants to spend no more
than $140 and the office can hold up to 72 ft2 of cabinets. How can the
storage volume be maximized?
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of 6 ft² to be purchased and y represent the number of 8ft² cabinet to e purchased.
x > 0 and y > 0
6 ft² cabinet cost $10 and 8 ft² cabinet cost $20, only $140 is available to spend, therefore the cost equation is:
10 x + 20 y ≤ 140
Also the office can hold only 72 ft², the space equation is:
6x + 8y ≤ 72
The volume equation is:
V = 8x + 12y
From the graph attached, we have to find the point with maximum volume by testing the point (12, 0), (0,7) , (8,3)
For (12, 0): V = 8(12) + 12(0) = 96 ft³
For (0, 7): V = 8(0) + 12(7) = 84 ft³
For (8, 3): V = 8(8) + 12(3) = 100 ft³
The (8,3) point has the maximum volume. That is 8 6 ft² cabinet and 3 8ft² cabinet
Geometry and Trigonometry
Answer:
a. 227 cm
b. 495 cm
Step-by-step explanation:
a. Radius of arc = sin(½θ) = 2.10/r
θ = (360-225)/2 = 67.5
Radius of arc = sin(67.5) = 2.10/r
r = 2.10/sin(67.5) = 2.273 m = 227 cm (nearest cm)
b. Length of arc = θ/360*2πr
Take π as 3.14
r = 210 cm
θ = 360 - 225 = 135°
Length of arc = [tex] \frac{135}{360}*2*3.14*210 = 495 cm [/tex] (to nearest cm)

If f is a differentiable function such that f′(x)≥6, find the largest value of ???? so that f(4)≥???? whenever f(2)=10. (Use decimal notation. Give your answer as exact number.)
Answer:
12
Step-by-step explanation:
If the slope of the function were exactly 6 on the interval between 2 and 4, then the increase on that interval from f(2) = 10 would be (4-2)·6 = 12. Since the slope is at least 6, the increase is at least 12, so ???? = 10+12 = 22.
The distance from Gillette, New Jersey, to Irvington, New Jersey, is 1 mile more than four times the distance from Irvington to Newark. If the total distance from Gillette to Newark is 2 miles less than six times the distance from Irvington to Newark, what is the distance from Irvington to Newark if all three cities are in a straight line?
Answer:
distance from Irvington to Newark
.= 3 Miles
Step-by-step explanation:
distance from Irvington to Newark.= X
distance from Gillette, New Jersey, to Irvington, New Jersey,= y
Y= 1+4x
total distance from Gillette to Newark
= z
Z= 6x-2
But total distance = x+y
Total distance= x+1+4x
Total distance= 1+5x
1 +5x= 6x-2
1+2= 6x-5x
3= x
distance from Irvington to Newark.= X
distance from Irvington to Newark
.= 3 Miles
distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+4x
distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+4(3)
distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+12
distance from Gillette, New Jersey, to Irvington, New Jersey,= 13 miles
Total distance= 1+5x
Total distance= 1+5(3)
Total distance= 16 miles

find the length of the hypotenuse !!
Answer:
17
Step-by-step explanation:
To find the hypotenuse, you would use the Pythagorean theorem.
[tex]A^{2} +B^{2} =C^{2}[/tex]
We can plug 8 and 15 into A and B\
[tex]8^{2} +15^{2} =C^{2}[/tex]
We can simplify this to
64+225=[tex]C^{2}[/tex]
289 = [tex]C^{2}[/tex]
To get C by itself not squared, we can do the square root of both sides.
[tex]\sqrt{289} =\sqrt{C^{2} }[/tex]
If we simplify, we get
17 = C or C = 17
Therefore the length of the hypotenuse is 17.

Solve the inequality for x. –2x + 3 < –13
Answer:
x > 8
Step-by-step explanation:
When you divide or multiply both sides of an inequality by a negative number, the equality is switched.
-2x + 3 < -13
(-2x + 3) - 3 < -13 - 3
-2x < -16
-2x/-2 < -16/-2
x > 8
Answer:
x > 8
Step-by-step explanation:
In order to solve the inequality for x, we must get x by itself on one side of the equation.
-2x + 3 < -13
3 is being added to -2x. The inverse of addition is subtraction. Subtract 3 from both sides of the equation.
-2x + (3-3) < (-13-3)
-2x < -13 -3
-2x < -16
x is being multiplied by -2. The inverse of multiplication is division. Divide both sides of the equation by -2.
-2x/-2 < -16/-2
When dividing or multiplying by a negative number, remember to flip the inequality sign.
-2x/-2 > -16/-2
x > -16/-2
x > 8
The solution to the inequality is x>8

Answer:
The slope of the line is -2.5.
Step-by-step explanation:
The formula to compute the slope of a straight line is:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The graph shows the gift card balance after buying 2 and 5 cups of medium coffee.
The two points provided are:
A = (1, 17.50)
B = (5, 7.50)
Compute the slope of the line as follows:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]=\frac{7.50-17.50}{5-1}\\\\=\frac{-10}{4}\\\\=-2.5[/tex]
Thus, the slope of the line is -2.5.

Step-by-step explanation:
The law of Sines applied to a Δ ABC is
[tex]\frac{a}{sinA}[/tex] = [tex]\frac{b}{sinB}[/tex] = [tex]\frac{c}{sinC}[/tex]
Using this in Δ HJL
[tex]\frac{z}{sinL}[/tex] = [tex]\frac{y}{sinH}[/tex] → (b)
Which may be expressed in reciprocal form as
[tex]\frac{sinL}{z}[/tex] = [tex]\frac{sinH}{y}[/tex] → (a)
Thus the law of Sines can be expressed as either (a) or (b)
