If you increase your bicycle speed by 5.6 miles per hour, the speed will be 17.9 miles per hour. What is your bicycle speed now?
Answer:
12.3 mph
Step-by-step explanation:
17.9 - 5.6 = 12.3
Answer:
12.3 mph
Step-by-step explanation:
Let x be our speed now
We increase the speed by 5.6 mph
Our new speed is x+5.6
We are going 17.9 mph
x+5.6 = 17.9
Subtract 5.6 from each side
x+5.6 -5.6 = 17.9-5.6
x =12.3
three classes at a junior high school raised money to buy new computers
•ms moore’s class raised $249.00
•ms aguilars class raised $396.62 more than ms.moores class
•mr.barrys class raised $430.43 less than ms.augilars class
what is the total amount of money raised by all three classes
Answer:
$1109.81
Step-by-step explanation:
$249.00 +$369.62= $618.62(ms. aguilars class)
$618.92-$430.43= $188.19(mr. barry's class)
$249.00+$618.62+$188.19=$1109.81(complete answer of all 3 classes combined)
Answer:
The final amount is $1109.81
Step-by-step explanation:
In order to find the total amount, start with the know amount, which is Ms. Moore's class. Her class raised $249. Now we can use that to find the amount from Ms. Aguilar's class.
$249 + $396.62 = $645.62
Now we can use the amount from Ms. Aguilar's class to find the amount from Ms. Barry's class
$645.62 - $430.43 = $215.19
Now we can add the three amounts together to find the total amount.
$249 + $645.62 + $215.19 = $1109.81
250 female nurses to 100 male nurses what is the ratio of male nurses to female nurses
Answer:
2:5
it may be faster to google it
Answer:
Required ratio is 2:5.
Step-by-step explanation:
Given that number of female nurses = 250
Given that number of male nurses = 100
Now we need to find about what is the ratio of male nurses to female nurses.
So we just need to divide number of male nurses by the number of female nurses. That means divide 100 by 250. We get:
[tex]\frac{male}{female}=\frac{100}{250}[/tex]
[tex]\frac{male}{female}=\frac{10}{25}[/tex]
[tex]\frac{male}{female}=\frac{2}{5}[/tex]
Hence required ratio is 2:5.

Tim Tradesman pays $2,000 annually for $150,000 worth of life insurance. Answer the following questions. a. At the end of 10 years, how much will Tim have paid in premiums? b. At the end of 10 years, what will the cash value of his policy be? c. What will the ratio of cash value to premiums paid be (as a percent)?
____________________________________________________
Explanation for question A:
We are trying to found the amount of money he payed after 10 years.
He pays an annual (yearly) of $2,000, so we would just multiply 2,000 by 10, since we are trying to find the amount he point in 10 years, in which he pays $2,000 a year.
[tex]2000*10=20000[/tex]
Answer for Question A: Tim Tradesman paid $20,000 in premiums at the end of 10 years.
____________________________________________________
Explanation for question B:
In question B, we are trying to find the cash value of the policy at the end of 10 years.
To find the cash value at the end of 10 years, we would get the units of life insurance and multiply it by the cash value per unit
There would be 150 units of life insurance.
So we multiply:
[tex]150*89=13350[/tex]
Answer for Question B: The cash value of his policy will be $13,350 at the end of 10 years.
____________________________________________________
Explanation for question C:
In question C, we are trying to find the ratio of cash value to premiums paid.
Our cash value is 13,350 and we paid 20,000.
When you subtract 20,000 and 13,350, you would get 6,650.
[tex]20000-13350=6650[/tex]
Then when you add 20,000 and 13,350, you would get 33,350.
[tex]20000+13350=33350[/tex]
When you subtract 6,650 from 33,350, you would get 26,700
[tex]33350-6650=26700[/tex]
26,700 is 66.75% of 33,350.
Answer for Question c: The ratio as a percent for the cash value to premiums paid is 66.75%

the table shows the number of minutes of exercise for each person. compare and contrast the measures of variation for both weeks. please answer quickly and thank you!
To compare the measures of variation for both weeks, calculate the range and standard deviation. Week 1 has a larger range and standard deviation compared to Week 2.
Explanation:
To compare and contrast the measures of variation for both weeks, we need to calculate the range and standard deviation for each week. The range is the difference between the highest and lowest values, while the standard deviation measures the average amount by which each data point differs from the mean.
For Week 1, the range is 90 (90 - 30), and the standard deviation is 25.62. For Week 2, the range is 30 (60 - 30), and the standard deviation is 11.55.
Therefore, Week 1 has a larger range and standard deviation compared to Week 2.

When Elyse moved last weekend, the circular glass top for an end table broke. To replace it, she bought a circular glass top with a diameter of 20 inches.
What is the approximate area of the circular glass top Elyse bought?
Answer:
A = 314 inches^2
Step-by-step explanation:
We know the diameter of the glass. We need to find the radius
d = 2r
20 = 2r
Divide each side by 2
20/2 = 2r/2
10 =r
To find the area of the glass
A = pi r^2
A = pi * 10^2
A = pi*100
A = 100 *(3.14)
= 314 in^2
Select the representation that does not change the location of the given point. (4, 110°)
Question 6 options:
(4, 290)°
(-4, 200)°
(4, 470)°
(-4, 470)°
Answer:
(4,470°)
Step-by-step explanation:
The representation that does not change the location of (4, 110°) in polar coordinates are all points that are coterminal with the given point.
The only point among the given options that is coterminal with (4, 110°) is (4, 470)°
The two points have the same magnitude and 470°-360°=110°.
Since 110° is coterminal with 470° and the two points have the same magnitude with the same sign, the two points represent the same location in polar coordinates.
The correct choice is (4,470°)
In the polar coordinate system, the point (4, 470°) is the representation that does not change the location of the given point (4, 110°). We obtain this by adding 360° to the given angle.
Explanation:This question is based on the concept of polar coordinates. Polar coordinates represent a point in space by specifying its distance from a reference point, usually the origin, and the angle made with the positive x-axis. In polar coordinates, (r, θ), 'r' represents the distance and 'θ' is the angle.
Given point is (4, 110°). We can notice that by adding or subtracting multiples of 360° from the angle, we are not changing the location of the point. So, if we add 360° to the 110°, we will obtain 470°. Hence, the point that represents the same location is (4, 470°).
The point (-4, 200°) represents the point in the opposite direction and the points (4, 290°) and (-4, 470°) change the angle beyond or below what is allowable without changing the point's location.

Final answer:
To find f(-9) in the given function, substitute -9 for x and evaluate by following the transformation rules.
Explanation:
We can rewrite a given function as y = f{-2(x+1)}. To find f(-9), we substitute -9 for x in the function.
This gives us f(-9) = f{-2(-9+1)}. Calculating further results in f(-9) = f{-2(-8)}.
Therefore, to find f(-9), we evaluate the function at x = -8, and the value depends on the specific function provided.

What is the amplitude, period, and phase shift of f(x) = −4 sin(2x + π) − 5?
Amplitude = −4; period = 2π; phase shift: x = -pie/2
Amplitude = −4; period = π; phase shift: x = pie/2
Amplitude = 4; period = π; phase shift: x = -pie/2
Amplitude = 4; period = 2π; phase shift: x = pie/2
Answer:
Amplitude = 4; period = π; phase shift: x = -pie/2
Step-by-step explanation:
For a sine wave of the following type:
y = Asin(Bx + C) + D, we have that:
A represents the amplitude
C represents the phase shift
D represents the vertical shift
And the period is given by: [tex]\frac{2 \pi}{B}[/tex]
Therefore, considering: f(x) = −4 sin(2x + π) − 5, we know that sin(a + π) = -sin(a). Then:
f(x) = −4 sin(2x + π) − 5 = 4sin(2x)-5 = 4cos(2x - π/2) - 5
The amplitude equals 4
The period is T = π
The fase shift is: -π/2.
Therefore, the correct option is:
Amplitude = 4; period = π; phase shift: x = -pie/2

The measure of a vertex angle of an isosceles triangle is 120° and the length of a leg is 8 cm. Find the length of a diameter of the circle circumscribed about this triangle.
ANSWER
The length of a Diameter is 3.714
EXPLANATION
The circumscribed triangle is shown in the attachment.
We use the cosine ratio to find the altitude of the isosceles triangle.
[tex] \cos(60 \degree) = \frac{altitude}{hypotenuse} [/tex]
[tex] \cos(60 \degree) = \frac{altitude}{8} [/tex]
Altitude =8cos(60°)
Altitude=4cm
Let the upper half of the altitude be y cm.
Then the radius of the circle is (y-4)cm
The upper radius meets the tangent at right angles.
From the smaller right triangle,
[tex] \sin(60 \degree) = \frac{4 - y}{y} [/tex]
[tex] y\sin(60 \degree) = 4 - y[/tex]
[tex]y\sin(60 \degree) + y= 4 [/tex]
[tex](\sin(60 \degree) + 1)y= 4 [/tex]
[tex]y= \frac{4}{\sin(60 \degree) + 1} [/tex]
[tex]y = 16 - 8 \sqrt{3} [/tex]
y=1.857
The diameter is 2y
[tex]d = 32 - 16 \sqrt{3} [/tex]
=2(1.875)
The length of a Diameter is 3.714
Answer:
Diameter of the circle is 16 cm.
Step-by-step explanation:
Given : The measure of a vertex angle of an isosceles triangle is 120° and the length of a leg is 8 cm.
To find : The length of a diameter of the circle circumscribed about this triangle?
Solution :
We construct a circle in which an ABC isosceles triangle is formed.
Refer the attached figure below.
The measure of a vertex angle of an isosceles triangle is 120° .
The length of a leg is 8 cm, AC=8 cm
Vertex angle is divided by the line touching the center of the circle.
So, [tex]\angle A=60^\circ[/tex] and line AD=radius of the circle
Applying property of isosceles triangle,
Now, ∠DAC=∠ACD=∠CDA=60°
AC=DC=8 cm
The radius of the circle is 8 cm.
The diameter of the circle is twice the radius.
Therefore, The diameter of the circle is d=2(8)=16 cm.

Given: m∠MEJ=30°, m∠MFJ=50° , Find: Measurement of Arc KL & Measurement of Arc MJ
Answer:
Part a) The measurement of arc KL is [tex]20\°[/tex]
Part b) The measurement of arc MJ is [tex]80\°[/tex]
Step-by-step explanation:
Let
x--------> the measure of arc KL
y-------> the measure of arc MJ
we know that
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
[tex]m<MEJ=\frac{1}{2}(y-x)[/tex]
substitute the given value
[tex]30\°=\frac{1}{2}(y-x)[/tex]
[tex]60\°=(y-x)[/tex]
[tex]y=60\°+x[/tex] ------> equation A
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
[tex]m<MFJ=\frac{1}{2}(x+y)[/tex]
substitute the given value
[tex]50\°=\frac{1}{2}(x+y)[/tex]
[tex]100\°=(x+y)[/tex]
[tex]y=100\°-x[/tex] ------> equation B
Equate the equation A and B and solve for x
[tex]60\°+x=100\°-x[/tex]
[tex]2x=100\°-60\°[/tex]
[tex]x=20\°[/tex]
Find the value of y
[tex]y=100\°-20\°=80\°[/tex]
therefore
The measurement of arc KL is [tex]20\°[/tex]
The measurement of arc MJ is [tex]80\°[/tex]
