I have a rectangular garden. I usually grow
carrots in 2/5 of my garden but I want to
take 1/4 of the carrots section to grow
strawberries. After I make this change, how
much of my whole garden will be
strawberries?
Answers
Answer:
[tex]\frac{1}{10}[/tex]
Step-by-step explanation:
If you originally have [tex]\frac{2}{5}[/tex] of your garden reserved for carrots, are taking [tex]\frac{1}{4}[/tex] of the carrot space ( [tex]\frac{2}{5}[/tex] ) for strawberries, then the total amount of your garden left for strawberries will be [tex]\frac{2}{5}\cdot\frac{1}{4}[/tex]
[tex]\frac{2}{5}\cdot\frac{1}{4} = \frac{2}{20}[/tex]
[tex]\frac{2}{20}[/tex] simplifies down to [tex]\frac{1}{10}[/tex].

Find x. Assume that segments that appear tangent are tangent.
Answers
Answer:
27
Step-by-step explanation:
FE is tangent to the circle with center D at point E and DE is radius.
[tex] \therefore FE \perp DE \implies m\angle FED = 90\degree [/tex]
DE = x
DF = x + 18
FE = 36
By Pythagoras theorem:
[tex] DF^2 = DE^2 + FE^2 [/tex]
[tex] (x+18)^2 = x^2 + 36^2 [/tex]
[tex] x^2 + 36x + 324= x^2 + 1296[/tex]
[tex] 36x + 324= 1296[/tex]
[tex] 36x = 1296-324[/tex]
[tex] 36x = 972[/tex]
[tex] x = \frac{972}{36}[/tex]
[tex] x =27[/tex]
The value of x from the given figure, which is radius of a circle is 27 units.
From the given figure, FE=36 units, DE=x units and FD=x+18 units.
What is the angle formed with tangent and radius?Tangent and radius of a circle meet at 90°. If we draw a radius that meets the circumference at the same point, the angle between the radius and the tangent will always be exactly 90°.
Using Pythagoras theorem, we have
FD²=FE²+DE²
⇒ (x+18)²=36²+x²
⇒ x²+36x+324=1296+x²
⇒ 36x=1296-324
⇒ 36x=972
⇒ x=972/36
⇒ x=27 units
Hence, the value of x from the given figure, which is radius of a circle is 27 units.

Write the rule that transforms p(x) into q(x), where q(x)=2p(x+3)−6
Answers
Answer: - A horizontal shift of 3 units to the left.
- A vertical dilation of factor 2.
- A vertical shift of 6 units down.
Step-by-step explanation:
Here we have 3 transformations:
I will start giving general cases for each transformation:
Horizontal shift.
When we have a function f(x), an horizontal shift to the right of N units (N positive) is written as:
g(x) = f(x - N)
So in our case, we have a shift to the LEFT of 3 units.
Vertical dilation/contraction.
A vertical dilation/contraction of factor A, is written as:
g(x) = A*f(x)
if A > 1, this is a dilation, if A < 1, this is a contraction.
In the case of our problem, we have A = 2.
Vertical shift:
A vertical shift is written as:
g(x) = f(x) + N.
If N is positive, we have a shift of N units up, if N is negative, we have a shift of N units down.
in this case, N = -6.
Then the transformations are:
q(x) = 2*p(x -(-3)) - 6
- A horizontal shift of 3 units to the left.
- A vertical dilation of factor 2.
- A vertical shift of 6 units down.

Answers
Answer:
[tex] -\frac{1}{40} [/tex]
Step-by-step explanation:
To evaluate [tex] -\frac{3}{8} - (-\frac{7}{20}) [/tex], start by opening the bracket.
When opening the bracket, we would be multiplying negative sign by negative sign, which equal positive sign.
Thus,
[tex] -\frac{3}{8} + \frac{7}{20} [/tex]
Solve further by performing addition operation to make both fractions one
The common denominator of 8 and 20 is 40,
[tex] \frac{5(-3) +2(7)}{40} [/tex]
[tex] \frac{-15 + 14}{40} [/tex]
[tex] \frac{-1}{40} = -\frac{1}{40} [/tex]
The answer of given expression in simplest form is: [tex]\dfrac{-1}{40}\\[/tex]
The given expression is:
[tex]-\dfrac{3}{8} - (-\dfrac{7}{20})[/tex]
Multiplying negative sign with negative sign will result in positive sign of the latter term.
The simplification will be done as follows:
[tex]\\-\dfrac{3}{8} - (-\dfrac{7}{20})\\\\= -\dfrac{3}{8} + \dfrac{7}{20}\\\\=\dfrac{-3 \times 5 + 7 \times 2}{40}\\\\= -\dfrac{1}{40}\\[/tex]

A researcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol. She feeds one group of laboratory rats a daily diet of precisely 41.59 units of niacin and 17,995 units of retinol. She uses two types of commercial pellet foods. Food A contains 0.22 unit of niacin and 100 units of retinol per gram. Food B contains 0.23 unit of niacin and 65 units of retinol per gram. How many grams of each food does she feed this group of rats each day
Answers
Answer:
Food A = 165 grams
Food B = 23 grams
Step-by-step explanation:
Daily precise diet fed to the group:
Niacin = 41.59 units
Retinol = 17,995 units
Two food types :
Food A :
Niacin = 0.22 units per gram
Retinol = 100 units per gram
Food B:
Niacin = 0.23 units per gram
Retinol = 65 units per gram
Let:
a = gram of food A fed per day
b = gram of food B fed per day
Hence in 'a' grams of food A:
0.22a of Niacin + 100a of Retinol
In 'b' grams of food B:
0.23b of Niacin + 65b of retinol
Recall :
Total Niacin = 41.59 ; total Retinol = 17995
Then,
0.22a + 0.23b = 41.59 - - - (1)
100a + 65b = 17995 - - - (2)
From (2) ; 100a + 65b = 17995
100a = 17995 - 65b
a = 179.95 - 0.65b - - - (3)
Substitute (3) into (1)
0.22(179.95 - 0.65b) + 0.23b = 41.59
39.589 - 0.143b + 0.23b = 41.59
0.087b = 2.001
b = 2.001 / 0.087
b = 23
Put b = 23 in (3)
a = 179.95 - 0.65(23)
a = 179.95 - 14.95
a = 165

Answer:
The z-scores are [tex]Z_{\frac{\alpha }{2} } = 0643[/tex] and [tex]Z_{\frac{\alpha }{2} } = - 0643[/tex]
Step-by-step explanation:
From the question we are told that
The middle of the distribution area considered is 48%
Now the rest of the area under the standard normal distribution area is mathematically evaluated
[tex]\alpha = 100- 48[/tex]
[tex]\alpha = 52 \%[/tex]
[tex]\alpha = 0.52[/tex]
Now to obtain the area occupied by this proportion at the two tails we divide by 2 i.e
[tex]\frac{\alpha }{2} = \frac{0.52}{2} =0.26[/tex]
Now the z-score is obtained from the normal distribution table and the value is

Show that the curve x = 7 cos(t), y = 5 sin(t) cos(t) has two tangents at (0, 0) and find their equations.
y = __________ (smaller slope)
y = __________ (larger slope)
Answers
The equations of the two tangents are; Larger slope; y = (5/7)x Smaller slope; y = (-5/7)x
What is the slope?Slope tells how vertical a line is.
The more the slope is, the more the line is vertical. When slope is zero, the line is horizontal.
To find the slope, we take the ratio of how much the line's height increases as we go forward or backward on the horizontal axis.
This is because the more the height of the line to thee amount we walk or run on the horizontal axis, the more the slope is. Thats why we took difference of horizontal axis in denominator and difference of vertical axis on numerator.
The curve x = 7 cos(t), y = 5 sin(t) cos(t) has two tangents at (0, 0) and we need to find their equations.
We can write
cos(t) = x/7
so
y = 5(±√(1 -(x/7)^2)*x/7
Then
y' = (±5/7)*(√(1 -(x/7)^2) + x/(2√(1 -(x/7)^2)*(-2(x/7))
The limit as x → 0 is ±5/7
The equations of the two tangents are;
Larger slope; y = (5/7)x
Smaller slope; y = (-5/7)x

Using these regression results, what is the estimated repair cost on a car that has 74,000 miles on it?
Answers
Answer:
797.42
Step-by-step explanation:
Given the Output of a linear regression data using R;
From the result table;
Intercept = 72.807562
Gradient or slope = 0.009792
General form of a linear equation:
y = mx + c
Where y = response variable ; x = explanatory variable ; c = intercept and m = gradient / slope
Hence, the regression equation becomes :
y = 0.009792x + 72.807562
Using these regression results, what is the estimated repair cost on a car that has 74,000 miles on it?
x = 74,000
y = 0.009792(74000) + 72.807562
y = 724.608 + 72.807562
y = 797.42
Answer:
The estimated repair cost on a car that has 74,000 miles on it is $797.42.
Step-by-step explanation:
The statement: Im(formula = Repair.Costs ~ Miles.Driven, data = Dataset) implies that the variable "Repair.Costs" is the dependent variable and the variable "Miles.Driven" is the independent variable.
From the provided data the regression equation formed is:
[tex]\text{Repair.Costs}=72.807562+0.009792\cdot \text{Miles.Driven}[/tex]
Compute the estimated repair cost on a car that has 74,000 miles on it as follows:
[tex]\text{Repair.Costs}=72.807562+0.009792\cdot \text{Miles.Driven}[/tex]
[tex]=72.807562+0.009792\cdot 74000\\\\=72.807562+724.608\\\\=797.415562\\\\\approx 797.42[/tex]
Thus, the estimated repair cost on a car that has 74,000 miles on it is $797.42.

For a 7 1/2 hour day, Ed makes $90. How much does he make in 1 hour?
Answers
Answer:
he makes $12 an hour
Step-by-step explanation:
Ed makes $6 in one hour.
To find out how much Ed makes in one hour, we can divide the total amount he makes in a 7 1/2 hour day by the number of hours in a day.
First, let's convert 7 1/2 hours to a mixed fraction.
7 1/2 hours = 7 + 1/2 = 14/2 + 1/2 = 15/2 hours.
Now, we can calculate how much Ed makes per hour by dividing the total amount he makes ($90) by the number of hours (15/2):
Amount per hour = $90 ÷ (15/2) = $90 × (2/15) = $6.
Therefore, Ed makes $6 in one hour.

c² = a² + b²(5x+20)² = (5x +19)² + x²25x² + 200x + 400 = 25x² + 190x + 361 + x²x² - 10x - 39 = 0Solving the quadratic equation we get:
x= 13Then:
a= 13 cmb = 5*13 +19 = 84 cmc= 5*13 + 20 = 85 cmSixty percent of the cost of the dining set is the same as one half the cost of the dining set decreased by $180. What is the cost of the dining set?
Answers
Answer:
The cost of the dining set = $200
Step-by-step explanation:
Let
Cost of the dining set=x
Sixty percent of the cost of the dining set
= 60% of x
=60/100 * x
= 0.6x
One half the cost of the dining set decreased by $180.
=1 1/2 of x - 180
= 1.5 * x - 180
= 1.5x - 180
Sixty percent of the cost of the dining set is the same as one half the cost of the dining set decreased by $180
0.6x = 1.5x - 180
Collect like terms
0.6x - 1.5x = -180
-0.9x = -180
Divide both sides by -0.9
x= -180 / -0.9
=200
x= $200
Check:
0.6x
= 0.6(200)
=120
1.5x - 180
=1.5(200) - 180
= 300 - 180
=120
