D. It takes them more time to deliver packages because 157.3 x 1.25 = 196.625
Step-by-step explanation:
In the question, it states that this week it took the delivery drivers 1.25 times longer to deliver packages than last week, meaning that it took more time to deliver the packages this week than last week. With this, we can eliminate choices A and C.
Because it took them 1.25 times longer, then we can multiply 157.3 by 1.25 to find the correct sum.
157.3 × 1.25 = 196.625
The only answer choice that matches this information completely is choice D, so that is the answer.

Chiletso just got a new cylindrical fish tank, which he plans to stock with a variety of african cichlids.
. the height of the cylindrical fish tank is 30 inshes.
. the length of the diameter of the base is 27.5 inches.
. one us gallon is equal to approximately 231 cubic inches.
. cichlids grow to approximately 6 inches.
. a good rule of thumb is to have about 3 inches of fish per 2 gallons of water.
calculate the maximum number of african cichlids chiletso can put in his tank.
The maximum number of African cichlids which can put by Chiletso in this cylindrical fish tank is 19.
What is of volume of cylinder?Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.
The volume of the cylinder can be given as,
V=(πd^2h)4
Here, (d) is the diameter of the base of the cylinder and (h) is the height of the cylinder.
The height of tank is 30 inches and the length of the diameter of the base is 27.5 inches. Thus, the volume of it is,
V=[π(27.5)²(30)] /4
V=17818.72 cubic inches.
One us gallon is equal to approximately 231 cubic inches. Thus, the volume in gallon is,
V=17818.72/231
V=77.12 gallons.
A good rule of thumb is to have about 3 inches of fish per 2 gallons of water. The number of 6 inches cichlids the can put in 77.12 gallons tank is,
V=(77.12 x 3)/(6 x 2)
V=19.28
Thus, the maximum number of African cichlids which can put by Chiletso in this cylindrical fish tank is 19.

A cube has a surface area of 181.5sq. In. What is the length of the sides
Answer:
Answer = 5.5
Step-by-step explanation:
The formula for finding the surface area of a cube is SA = 6(s^2) where s = sides. Since we know the surface area we plug it in for SA. So,
181.5 = 6*s^2
Now we divide 6 by both sides to get
30.25 = s^2
Now we have to find the square root of both sides to get
5.5 = s

The hcf of 182 and x is 26 and the l.c.m of 182 and x is 1092 determine the value of x
The value of x such that the hcf is 26 and the l.c.m is 1092 is 156
How to determine the value of x?The numbers are given as:
182 and x
The HCF and LCM are given as:
HCF = 26
LCM = 1092
As a general rule;
The product of LCM and HCF of x and y equals the product of x and y
So, we have:
182 * x = 26 * 1092
Divide both sides by 182
x = 156
Hence, the value of x is 156

D.
The graph of g is the graph of fshifted 2 units down.
Answer:
D. The graph of g is the graph of f shifted 2 units down.
Step-by-step explanation:
Transformations
f(x) - a : vertical shift of "a" units down
f(x) + a : vertical shift of "a" units up
f(x - a) : horizontal shift of "a" units to the right
f(x + a) : horizontal shift of "a" units to the left
If g(x) = f(x) - 2

Which mass is least 1500 mg, 13.2 kg, 30000 cg, 7428g
Answer:
1500 mg is the least mass
Step-by-step explanation:
Lets convert them all to the same mass unit,
1500 mg to grams: 1500 mg / 1000 = 1.5 grams
13.2 kg to grams: 13.2 kg x 1000 = 13,200 grams
30000 cg to grams: 30,000 cg / 100 = 300 grams
7428g no conversion needed!
1.5 grams, 13,200 grams, 300 grams, 7,428 grams

The sum of 1/2 and y is equal to 3/4. Enter the equation that represents the description
Answer:
1/2 + y = 3/4Step-by-step explanation:
The sum of 1/2 and y is equal to 3/4.
The equation to represent this is:
1/2 + y = 3/4A particular tree falls over in a bonsai forest and is considered to be an average tree (in the middle 20%). If the mean height is 10cm and the standard deviation is 2 between what heights must the tree be?
Using the normal distribution, it is found that the tree must have heights between 9.49 cm and 10.51 cm.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 10, \sigma = 2[/tex]
Considering the symmetry of the normal distribution, the middle 20% is between the 40th percentile(Z = -0.253) and the 60th percentile(Z = 0.253), hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.253 = \frac{X - 10}{2}[/tex]
X - 10 = -0.253 x 2
X = 9.49.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.253 = \frac{X - 10}{2}[/tex]
X - 10 = 0.253 x 2
X = 10.51.

Question, if 1 = 10, 2 = 12, 3 = 14, and 4 = 16, what would 5 equal?
Answer:
5=18
Step-by-step explanation:
they are counting by 2s 10,12,14,16,18
Hope this helps!
Answer:
18
Step-by-step explanation:
It seems like for this pattern, as the x-value(base value) increases, the corresponding y-value(value changing with the base value) increases by 2 given that the function starts with a y-intercept of 8. So at the value 0, the corresponding number would be 8. So in this case, by creating a function regrading this information we can solve for the corresoponding value of 5: y = 2x + 8
y = 2 * 5 + 8
y = 10 + 8
y = 18
5 = 18
Another way to approach this is just by following the pattern given to us in the description. We see that the pattern starts at 10, and increases by 2 for each increasing base value. Therefore, if 4 = 16, then 16 + 2 = 5, so 5 = 18.

Select all ordered paris that satisfy the function,
y = -3x + 9
A. (-2, 15)
B. (1, -6)
C. (3, 0)
D. (6, 1)
Answer:
(-2,15) (3,0)
Step-by-step explanation:
By substituting the x value in the coordinate (the first number in the bracket) and solving the equation, you must get the y value in the coordinate (second number in the bracket.
So that is to say:
A
y= -3x + 9
y = -3(-2) + 9
y = 6 + 9
y= 15
Also note that B is not one of them, because the y value you get when you substitute the x value in the equation is NOT NEGATIVE 6.

302.1 in a fraction form
Answer:
302 1/10 is our fraction form more known to be a mixed number.
Step-by-step explanation:
Fraction form from decimal is to keep our 302 and make .1 a fraction.
This is because we already have a base/whole number and just need a fraction to make this decimal an improper fraction. 0.1 is equivalent to 1/10 because in order to get to 0.1 you need to move the decimal point 1 digit to the right. You could also do 1 divided by 10.
302 1/10 is our fraction form more known to be a mixed number.
