Write a fraction that is equivalent to 3/4 with a denominator of 20
Answer:
15/20
Step-by-step explanation:
1. Take the denominator of 3/4 and multiply it by 5 because that is what it takes to get 20 from 4.
4 x 5 = 20.
2. Multiply the numerator by 5 as well.
15/20
Answer:
3 / 4 = 15 / 20

Answer:
y=9
Step-by-step explanation:
they grow together by the same amount
Answer:
27/2...or 13.5 as a decimal
Step-by-step explanation:
the ratio of y and x is y/x or, 9/2 with 9 being the y and 2 being the x
the X changed to 3, so y/3 is the new ratio. Since we have another ratio, we can compare them to get the y
the equation : 9/2=y/3--2x=27--
x=27/2

Tom is buying topsoil for the flower bed shown below. One bag of topsoil covers 151515 square meters. How many bags of topsoil does Tom need to cover his flower bed?
Answer:
2 bags of topsoil.
Step-by-step explanation:
The attached figure shows a flower bed.
One bag of topsoil covers 15 square meters.
We need to find how many bags of topsoil does Tom need to cover his flower bed.
The area of the flower bed is :
[tex]A=\dfrac{1}{2}\times 12\times 5\\\\=30\ m^2[/tex]
Let he has to cover x bags of topsoil. So,
x = Area of flower bed/Area of 1 bag of top soil
x = 30/15
x = 2
Hence, he will need 2 bags of topsoil to cover his flower bed.

Which of the statements is true
a. v7 is an integer
C. V25 is a rational number
b. V16 is an irrational number
d. 190 is neither rational nor irrational number
Answer:
The only valid choice is c.
Step-by-step explanation:
Rational Numbers
Rational numbers have the form a/b, where a and b are integers and b is not zero.
In other words, rationals are all numbers that can be written as a fraction.
Examples are -3/7, 11/2, 5, 0
Note the last two numbers are integers, but they are also rationals because an integer can be expressed as a fraction with a denominator of 1.
Irrational numbers are the opposite, they cannot be expressed as a fraction.
a. [tex]\sqrt{7}[/tex] is not an integer since it's irrational. False
c. [tex]\sqrt{25}[/tex] = 5 or -5. It is a rational number because it's an integer. True
b. [tex]\sqrt{16}[/tex] = 4 or -4. It is not an irrational number because it's an integer. False
d. 190 is a rational number. False
The only valid choice is c.

In the diagram below, triangle ABC is drawn with altitude BD. If AD = 30 and AC = 36, determine the length of AB rounded to the nearest tenth.
9514 1404 393
Answer:
32.9
Step-by-step explanation:
The ratio of long side to hypotenuse is the same for all of the triangles in the figure.
AD/AB = AB/AC
AB^2 = AD·AC = 30·36
AB = 6√30 ≈ 32.863
To the nearest tenth, AB ≈ 32.9.

find an equation of the line that is perpendicular to the line y=5x+6 and passes through the point (-2,5)
workings pls
Answer:
[tex]5y=-x+23\\[/tex]
Step-by-step explanation:
Since the equation of the line is perpendicular to the line y = 5x +6
we can use the formula:
[tex]m_1m_2=-1\\[/tex]
where m1 is the slope of the line we have and,
m2 is the slope of the line we need
so here m1 is 5 as we compare it with the slope-intercept form our slope is:
[tex]y=5x+6\\y=mx+b[/tex]
our m1 is 5 but we need m2 so plugging in the value we get m2 to be:
[tex]m_1m_2=-1\\5m_2=-1\\m_2=-1/5\\[/tex]
and now we have our m2, now furthermore since the line passes through the point (-2 , 5) it means the point must lie on the line and satisfy it. We can use this point and the slope m2 and find out the equation by the point-slope form equation:
[tex]y-y_1=m(x-x_1)\\y-5=-\frac{1}{5}(x-(-2))\\\\5(y-5)=(-1)(x+2)\\5y-25=-x-2\\5y=-x-2+25\\5y=-x+23\\[/tex]
Which unit rate is equivalent to 13 miles per gallon? 1) 26 miles 2 galons 2) 2 gallons 26 miles 3) 39 miles 4 gallons 4) 4 gallons 4 39 miles please answer fast!
Answer:
1)
Step-by-step explanation:
We just need to find a rate where the ratio of miles to gallons is 13:1
This only works for 1) 26 miles 2 gallons since 26/2 = 13/1
Answer:
I think it would be the first one. 26 miles 2 gallons
Step-by-step explanation:
Every gallon would be 13 miles. If you multiply 13 by 2 and 1 gallon by 2, you'll get 26 miles 2 gallons.

Given: x + 2 <-5.
Choose the solution set.
OXIXER,<-7)
OXIXERX <-3)
OxIXER X<3)
OXIXER X<7)
Answer:
The solution set is {x : x ∈ R, x < -7} ⇒ A
Step-by-step explanation:
The solution set of the inequality x > a is {x : x ∈ R, x > a}The solution set of the inequality x < a is {x : x ∈ R, x < a}The solution set of the inequality x ≥ a is {x : x ∈ R, x ≥ a}The solution set of the inequality x ≤ a is {x : x ∈ R, x ≤ a}Let us solve the question
∵ x + 2 < -5
→ Subtract 2 from both sides of the inequality
∴ x + 2 - 2 < -5 - 2
∴ x + 0 < -7
∴ x < -7
→ By using the second rule above
∴ The solution set is {x : x ∈ R, x < -7}

From a point 300 feet above ground in a firetower, a ranger spots two fires in the George Washington National forest. The angle of depression made by the line of sight from the ranger to the first fire is 3oand the angle of depression made by the line of sight from the ranger tothe second fire is 2o. The angle formed by the two lines of sight is 0117. Find the approximate distance between the two fires.
Answer:
The answer is "[tex]\bold{17456.6 \ ft}[/tex]"
Step-by-step explanation:
Please find the complete question in the attached file.
[tex]\sin \theta = \frac{P}{h}\\\\\to BC =x\\\\\to BD =y\\\\[/tex]
The height of tower (AB) = 300 ft
Distance = CD
[tex]\Delta ABC \\\\\sin \theta = \frac{AB}{AC}\\\\\sin (2.5) = \frac{300}{AC}\\\\Ac= \frac{300}{\sin (2.5)}\\\\AC= 6877.68 \\\\\Delta ABD \\\\\sin \theta = \frac{AB}{AD}\\\\\sin (1.3) = \frac{300}{AD}\\\\AD= \frac{300}{\sin (1.3)}\\\\AC= 1322.33[/tex]
calculating CD :
[tex]CD^2 = AC^2 +AD^2 -2\cdot AC \cdot AD \cdot \cos(117^{\circ}) \\\\CD = \sqrt{(6877.68)^2 +(13223.23)^2 -2\cdot (6877.68) \cdot (13223.23) \cdot \cos(117^{\circ})}\\\\CD =\sqrt{47302482.1824 + 174853811.6329 - 82576463.207}\\\\CD= \sqrt{304732757.02}\\\\CD= 17456.6 \ ft[/tex]

Step-by-step explanation:
Each week Josie's mother pays her an allowance to mow and water their front yard. Her mother pays her twice as much to mow the yard as she does to water the yard. She gets a total of $45.00 each week. How much does Josie's mother pay her to mow the front yard? Write an equation and solve the equation.
Answer: $30
Step-by-step explanation:
Let the amount paid to water the yard be represented by x.
Since her mother pays her twice as much to mow the yard as she does to water the yard. Therefore, the amount to mow the yard would be 2x.
Therefore,
2x + x = $45
3x = $45
x = $15
The amount to mow the front yard would be:
= $15 × 2
= $30
