The children in a school were asked how many cats and dogs
they have. The ratio of cats to dogs is 3 to 2. The children have
150 cats altogether. How many dogs do the children have?
Answer:
90 cats 60 dogs
Step-by-step explanation:
3x +2x = 150
5x = 150
x = 30
3(30) + 2(30) = 150
90 + 60 = 150
3/2 = 1.5
90/60=1.5

A sphere and a right cylinder have the same radius and volume. The cylinder has a height of 8 feet. Find the radius.
tyyy
9514 1404 393
Answer:
6 feet
Step-by-step explanation:
The volume of a cylinder is given by ...
V = πr^2·h
For a sphere, the volume is ...
V = 4/3πr^3
You want the volumes to be the same when h=8, so we have ...
πr^2·8 = 4/3πr^3
Dividing by πr^2, we have ...
8 = 4/3r
r = 3/4·8 = 6
The radius is 6 feet.

Write the quadratic equation in standard form.
Step-by-step explanation: If we want to put this in standard form, we first want to add 2x² to both sides of the equation to get 2x² + 5x - 17 = 0.
Notice that I have set up the left side of the equation in descending order of powers. In other words, first the x² term, then the x term, then the constant term.

Which expression is equivalent to (-18) - 36n?
Answer:
D
Step-by-step explanation:
-18 - 36n = -6(3 + 6n).
Use distributive property.
-6(3 + 6n)
-18 + (-36n)
-18 - 36n
-18 - 36n = -18 - 36n
Have a nice day!
Answer:
D. -6 (3 + 6n)
Step-by-step explanation:
When you distribute [tex]-6 (3 + 6n)[/tex], you get [tex]-18 + -36n.[/tex]
[tex]-18 + -36n = (-18) - 36n.[/tex]

Step-by-step explanation:
A line passes through the point (12,-4) and is perpendicular to the line with the
equation y = 6x + 3. What's the equation of the line?
A) y = 6x - 76
B) y= -1/64 - 2
C) y= -4/5x+ 2
D) y = -6x + 68
Answer:
y = -1/6x - 2
Step-by-step explanation:
y = -1/6x + b
-4 = -1/6(12) + b
-4 = -2 + b
-2 = b
PLEASE HELP ME W A MATH PROBLEM!!!
Answer:
A) 296
Step-by-step explanation:
we have to find the angle of angle 5 since we know angle 6. Angle 6 is 32 so we will subtract 32 from 180 since straight lines are 180 degree angles (even though it doesn't look like one). This will give us 148. Since angle 5 and 4 are alternate interior angles, they have the same angle measurements. 148 + 148 = 296. Thus, angle 5 + angle 4 = 296 degrees.
The weight, in pounds, of a newborn baby t months after birth can be modeled by the equation W=10+2t What is the slope of the equation and what is its interpretation in the context of the problem?
Answer:
m = 2
Step-by-step explanation:
W=10+2t has the form y = mx + b, the slope-intercept form. Comparing
y = b + mx to
w = 10 + 2t
we see that the slope, m, is 2. This signifies that the baby gains 2 pounds per month shortly after birth.

A student is standing 20 feet away from the base of a tree. he looks to the top of the tree from a 50 degree angle of elevation. His eyes are 5 feet above the ground. using cos 50°≈0.64, what is the height of the tree to the nearest foot?
A. 29 feet
B. 24 feet
C. 31 feet
D. 36 feet
Answer:
A. 29 feet
Step-by-step explanation:
Use cos to find the hypotenuse
cos = adj/hp
0.64 = 20/hyp
hyp = 20/0.64
hyp = 31.25
---------------------------
Use Pythagorean Theorem to find the height of tree above eyes
a² + b² = c²
a² + 20² = 31.25²
a² = 31.25² - 20²
a² = 576.5625
a = 24 (to the nearest foot)
-------------------------------
Finally add in the eye height
h = 24 + 5
h = 29 feet
Answer:
A. 29 feet

Ten cards numbered 1 through 10 are mixed together and then one card is drawn. Find the probability of each event. Write each answer as a fraction, percent, and decimal. P(less than 5) P(greater than 3) P(odd) P(even) P(not a multiple of 4) P(not 5, 6, 7, or 8) P(divisible by 3)
Answer:
2/5, 0.4, 40%
7/10, 0.7, 70%
1/2, 0.5, 50%
1/2, 0.5, 50%
4/5, 0.8, 80%
3/5, 0.6, 60%
3/10, 0.3 ; 30%
Step-by-step explanation:
Sample space = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
P(less Than 5) :
Required = (1, 2, 3, 4) = 4 observations
P(less than 5) = 4 / 10 = 2 / 5 = 0.4 = 40%
Greater than 3) = (4, 5,6,7,8,9,10) = 7 observations
P greater Than 3) = 7/10 = 0.7 = 70%
Odd = (1,3,5,7,9) = 5
P(odd) = 5 / 10 = 1/2 = 0.5 = 50%
(even) = (2,4,6,8,10) = 5
P(even) = 5 / 10 = 1/2 = 0.5 = 50%
Not a multiple of 4 = (1,2, 3,5,6,7,9,10) = 8
P(not A multiple of 4) = 8/10 = 4/5 = 0.8 = 80%
not 5, 6, 7, or 8 = (1,2,2,4,9,10).= 6
P(not 5, 6, 7, or 8) = 6 / 10 = 3/5 = 0.6 = 60%
Divisible by 3 = (3, 6, 9) = 3
P(divisible by 3). = 3/10 = 0.3 = 30%

Your classmate is unsure about how to use side lengths
to determine the type of triangle. How would you explain
this to your classmate?
Answer:
you look at the lengths some triagles have small parallel lines anè or two of them to determine if they are equal or different from one another
triangle is: if:
right c^2=a^2 +b^2
acute c^2<a^2 +b^2
obtuse c^2>a^2 +b^2
Write the equation in slope intercept form?
Answer:
A
Step-by-step explanation:
The linear equation in two variables is given to us is
→ y = 3( x -4) +6x
Slope Intercept Form :-
The slope intercept form of the equation is y = mx + c .→ y = 3x - 12 + 6x
→ y = 6x + 3x -12
→ y = 9x - 12
