which ways more a cat that weighs 5.5 kg or a bag of flour that weighs 15 lb note 1 lb is about 45 kg
Answer:
the bag of flour
Step-by-step explanation:
if that cats weighs 5.5 kg and the bag of flower is 15 ib and 1 ib 45 ib so in 15 ib if we multiply 45 times 15 we get 675 and 675>5.5

Question in the image
Answer:
True, True, False, True
Step-by-step explanation:
Answer:
1. True
2. True
3. False
4. True
Step-by-step explanation:
A set of weights includes a 5 lb barbell and 4 pairs of weight plates. Each pair of
plates weighs 20 Ib. If x pairs of plates are added to the barbell, the total weight
of the barbell and plates in pounds can be represented by f(x) = 20x+ 5.
What is the range of the function for this situation?
A {0, 1, 2, 3, 4}
B {5, 25, 45, 65, 85}
C {0, 20, 40, 60, 80}
D {5, 45, 85, 125}
Answer:
The answer to this question would be B:
Based on the question, since the weight of the weight plates are 20 lbs, this would be represented by the 20x in the function. As well, the 5 lb barbell would be represented by the 5 in the function. The range of the function is determined by the amount of weight plates are added. So if I added one weight plate the equation would equal, f(x) = 20(1) + 5 = 25. This continues on the more and more weight plates you add.
Hope this reached you well :)
Step-by-step explanation:
20 = weight of the weight plates
x = amount of weight plates.
5 = weight of the barbell
f(x) = 20(0) + 5 = 5
f(x) = 20(1) + 5 = 25
f(x) = 20(2) + 5 = 45
f(x) = 20(3) + 5 = 65
f(x) = 20(4) + 5 = 85

Nike is having a sale on sweatpants. The regular price of sweatpants is $75. During the sale, all
sweatpants are 25% off the regular price. If you are using a credit card to pay, you receive an extra 15%
off of the sale price. Maria wants to buy a pair of sweatpants from the store. In order to calculate her
final price, Maria added the two discounts and took 40% off of the original price.
Maria's math work:
(1 -0.40) x 75 = $45
Is Maria’s math work correct? If not, what is the final price of the sweatpants for someone who is
paying with a credit card?
Answer:
I think it is wrong and the price is $55.
Suppose 40% of all college students have a computer at home and a sample of 64 is taken. What is the probability that more than 30 of those in the sample have a computer at home? 0.3686 0.1314 0.8686 0.6314 0.1343
Answer:
0.13093
Step-by-step explanation:
Give. That :
Population mean = 40% = 0.4
Sample size (n) = 64
Probability that more than 30 have computer at home
Mean = np = 64 * 0.4 = 25.6
Standard deviation = sqrt(n*p*(1-p)) = 3.919
P(x > 30)
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (30 - 25.6) / 3.919 = 1.1227353
p(Z < 1.122) = 0.13093 ( Z probability calculator)

A positive real number is 4 less than another. When 8 times the larger is added to the square of the smaller, the result is 96. Find the numbers.
Answer:
A positive real number is 4 less than another.
So, the other number is a - 4
When 8 times the larger is added to the square of the smaller, the result is 96.
As a is positive, there is only one solution which is.
=4\square root of (5)
If a different positive real number is 4 smaller than the first. The number 96 is obtained by adding 8 times the bigger to the square of the smaller. The lower number is 4·(√5 - 1), whereas the larger number is 4·√5.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
Suppose x represent the large number, the smaller number is obtained s,
= x - 4
From the given condition when 8 times the larger is added to the square of the smaller, the result is 96.
=8 × x + (x - 4)² = 96
=8x + x² - 8x + 16 = 96
=8x - 8x + x² + 16 = 96
=x² + 16 = 96
⇒x² = 96 - 16 = 80
⇒x = ±√(80)
⇒x= ±4·√5
Thus, if a different positive real number is 4 smaller than the first. The number 96 is obtained by adding 8 times the bigger to the square of the smaller. The lower number is 4·(√5 - 1), whereas the larger number is 4·√5.

Which is the Slope-Intercept form of an equation for the line containing the point (0,-3) with a slope of -1?
Answer:
y = -x - 3
Step-by-step explanation:
Slope(m) = -1
(0 , -3)
Equation: y - y1 = m(x -x1)
y - [-3] = -1(x - 0)
y + 3 = -1*x
y + 3 = -x
y = -x - 3

Using the discriminant, determine the number of real solutions.
-2x2+x-28 = 0
O A. no real solutions
O B. one real solution
O C. two real solutions
Answer:
A
Step-by-step explanation:
For a quadratic equation in standard form:
[tex]ax^2+bx+c=0[/tex]
The discriminant, symoblized as Δ, is given by:
[tex]\Delta=b^2-4ac[/tex]
If:
Δ>0 (positive), then our quadratic has two real roots. Δ<0 (negative), then our quadratic has no real roots. It does, however, have two imaginary (complex) roots. And if Δ=0 (zero), then our quadratic has exactly one real root.We have the equation:
[tex]-2x^2+x-28=0[/tex]
Thus:
[tex]a=-2, b=1, c=-28[/tex]
Substituting them for our discriminant:
[tex]\Delta=(1)^2-(4)(-2)(-28)[/tex]
Evaluate:
[tex]\Delta=1-224=-223<0[/tex]
Since our discriminant is negative, there is no real solutions.
Hence, our answer is A.
