(-25)/(-5)
step 2
(-25)/(-5) divide the equation by 5
answer
=5
Answer: 5
Step-by-step explanation:
Multiplying or dividing a negative by a negative results in a positive.
[tex](-10)/(-2)=5[/tex]
Multiplying or dividing a negative by a positive results in a negative.
[tex](-10)/(2)=-5[/tex]
Multiplying or dividing a positive by a negative results in a negative.
[tex](10)/(-2)=-5[/tex]
Multiplying or dividing a positive by a positive results in a positive.
[tex](10)/(2)=5[/tex]
Thus, because -25 and -5 are both negatives, the answer must be positive.

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]
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!
Answers
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.

C. V25 is a rational number
b. V16 is an irrational number
d. 190 is neither rational nor irrational number
Answers
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.

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?
Answers
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.

Question 5. No they are not balanced.
Step-by-step explanation:
1.

56/9 = 6 2/9
2.
8 + 11.5 = 20.5
19.5 ≠ 20.5
3.
23.42 - 8 = 15.42
15.42 = 15.42

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

Answers
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}
