The animal rescue has 3 cats for
every 8 dogs. If there are 20 more
dogs than cats, how many dogs are
there?
dogs
Answer:
32
Step-by-step explanation:
8-3=5
20÷5=4 sets
Hence, no. of dogs=4×8

Explain how you know that the sums of 12.6,3.1 and 5.4 is greater than 20
Answer:
2.6+3.1+5.4 =21.1
if you have 20
subtract 21.1-20
then you have 1.1
since the difference is 1.1 then we say
21.1>20
is -6.75 a whole number integer or rational number?
Answer:
I'm pretty sure it's rational.
Sorry if I'm wrong.
if 5(x-6)=8 then x=?
2(x - 3) - 4(x - 6) = 7x
2x - 6 - 4x + 24 = 7x
-2x + 18 = 7x
-2x - 7x = -18
-9x = -18
x = -18 ÷ (-9)
x = 2
5(x - 6) = 8
5x - 30 = 8
5x = 8 + 30
5x = 38
x = 38/5

The volume of a crate with length of x feet, width of 8 - x feet, and a height of x - 3 feet is given by V(x)=x(8−x)(x−3) find the maximum volume of the crate and the dimensions for this volume
1) Convert the following to decimals:
a) 25% b) 60% c) 72.1%
d) 7%
e) 9.5%
f).66%
25% = 25% : 100% = 0,25 ← the end
60% = 60% : 100% = 0,6 ← the end
72,1% = 72,1% : 100% = 0,721 ← the end
7% = 7% : 100% = 0,07 ← the end
9,5% = 9,5% : 100% = 0,095 ← the end
66% = 66% : 100% = 0,66

Find the length indicated? Need HELP!!! Will give a lot of point. Show work!!
Answer:
JH = 15
Step-by-step explanation:
KJ = 10
KI = 14
IH = 11
JH = ?
In order to find JH, we need to find JI, then add it to IH, which is 11. Here's the equation:
JH = JI + 11
In order to find JI, we need to subtract KJ from KI. Here's the equation:
14(KI) - 10(KJ) = JI
14 - 10 = 4
JI = 4
Now we plug in the numbers from our first equation:
JH = JI + 11
JH = 4 + 11
JH = 15
Answer:
JH= 15Step-by-step explanation:
Let KJ= 10, KI= 14, and IH= 11KI - KJ = J14 - 10 = 4J + IH = JH4 + 11 = 15[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]

Stanley analyzes the table of values for a polynomial function. He has determined through applying Descartes’ rule of sign that there is 1 negative real zero, and either 1 or 3 positive real zeros. He has also determined that the upper bound of the function is 3.
X , f(x)
-2, -105
-1, 0
0, 5
1, -2
2, 3
3, -20
4, -175
a. What is the degree of the polynomial function? How can you tell?
b. How many positive real zeros does the function have? How can you tell?
9514 1404 393
Answer:
a) 4
b) 3
Step-by-step explanation:
a. The total number of real and complex zeros is equal to the degree of the polynomial. That total is (1 negative real) + (3 positive real/complex) = 4 total zeros. The degree of the polynomial is 4.
The even degree is confirmed by the answer to part b, and by the end-behavior shown in the table, which has a tendency to -∞ for |x|→∞.
__
b. The intermediate value theorem tells you there will be zeros in the intervals (0, 1), (1, 2), and (2, 3) according to the values in the table. (The function changes sign in those intervals.) Thus there are 3 positive real zeros.
_____
Additional comment
Stanley cannot tell anything about Descartes' rule of signs by analyzing the table of function values. To use that rule, he must have terms of the polynomial. If he has those terms, he already knows the degree of the polynomial.

if angle 1 and angle 2 are vertical angles, angle 2 and angle 3 are complementary angles and the measure of angle 3 is 56 degrees find measure of angle 1
Answer:
34º
Step-by-step explanation: so basically you know a complementary angle is 2 angles that make a straight line and a vertical angle crosses which means 2 angles are congruent to each other so I drew a line that bisected the angle by drawing a line that cut through the right angle and i extended a line down from the right angle so now I have a vertical angle and a complementary so from here I labeled each angle <1 <2 <3 If I know angle 3 is 56º then I know 56 plus __ equals 90º I then subtracted 56 from 90 and I got 34 and since I am trying to figure out what angle 1 is I know that angle 1 and 2 are vertical angles therefore I know they are congruent to each other so <1 = 34º

Find cos(x) if [tex]\frac{sin^2x-1}{cosx} =-1[/tex].
A -1
B 2
C 1
D 0
(sin²(x) - 1)/cos(x) = -1
-cos²(x)/cos(x) = -1
-cos²(x) = -cos(x)
cos²(x) - cos(x) = 0
cos(x) (cos(x) - 1) = 0
Then it follows that cos(x) = 0 or cos(x) = 1. But if cos(x) = 0, then the original expression on the left side of the equation would be undefined. Then C is the only valid solution.
Find the length the length of AB.
Answer:
19 cm

I believed the answer is 19 cm because
AC = 7cm
CB= 12cm
AB= AC+CB
AB= AC+CBAB=7cm+12cm
AB=19cm

Which of the following is equal to the rational expression when x ≠ -1 or -7?
(X+1)(x-1)
——————
(X+7)(x+1)
A. x+1
——
x+7
B. x+7
———
x-1
C. x-1
——
x+7
9514 1404 393
Answer:
C. (x -1)/(x +7)
Step-by-step explanation:
The factor (x +1) in the numerator cancels the same factor in the denominator, leaving the ratio (x -1)/(x +7). This matches choice C.
_____
Additional comment
Even though (x+1)/(x+1) = 1 and can be removed from the expression, the fact that it is undefined at x=-1 means the reduced ratio (x-1)/(x+7) is only a valid representation of the original ratio when x≠-1. The factor (x+1) may be gone, but the domain restriction associated with it remains.

If the hypotenuse of a right triangle is 6 m and the one side is 4 m, what's the length of the other side?
Step-by-step explanation:
We can use the Pythagorean theorem to solve for side b:
[tex]c^2 = a^2 + b^2 \Rightarrow b^2 = c^2 - a^2[/tex]
or
[tex]b = \sqrt{c^2 - a^2} = \sqrt{(6\:\text{m})^2 - (4\:\text{m})^2}[/tex]
[tex]\:\:\:\:= 4.47\:\text{m}[/tex]
Answer: 2√5 or 4.47213595
Step-by-step explanation:
Use the Pythagorean Theorem: a^2 + b^2 = c^2
(a and b are the measures of the legs and c is the measure of the hypotenuse.)
Let's solve for a (the length of the other leg)
*I hope that m is not a variable and just an abbreviation for meters.
b = 4 m
c = 6 m
a^2 + 4^2 = 6^2
a^2 + 16 = 36
a^2 = √20
a = 2√5 = 4.47213595
