Can someone please help with these two questions?
Answer:
For question 2, it is C) 3a.
For question 3, it is B) 3.
Step-by-step explanation:
For question 2, we are given that Mary's age is a and her mother's age is 3 times as old as Mary. The key word is "times" so this means that the expression can be written as 3a or 3 * a.
For question 3, the question asks for the greatest number that divides evenly into both 42 and 81. Using simple math, C and D automatically elliminates itself because one of the numbers divided gives a whole and the other gives a decimal. All is left is A and B. Obviously, a number divided by one will by itself so it stays even either way and the two numbers divided by 3 will give us two whole numbers and 3 is the greatest possible number so that concludes that it is B.
Find the median of the data set
3/8 3/4 9/16 7/12
Answer:
7.5
Step-by-step explanation:
To find the median you must align all the numbers least to greatest so the order goes like this. 3,3,4,7,8,9,12,16. Then you must find the number in the middle. since there is not a number in the middle you add 7 and 8 together and then divide by 2 which is 7.5
A grocery store received two shipments of watermelon. Each watermelon in a shipment was weighed, then a line plot was made of all of the weights in a shipment.
What statement about the two plots’ distributions is true?
The degree of overlap between the two distributions is high.
There is no overlap between the two distributions.
The degree of overlap between the two distributions is low.
The degree of overlap between the two distributions is moderate.
Two line plots with the same scale and interval, from fifteen to twenty-five, with tick marks every one unit. The plots are stacked vertically for comparison. Values appear as x marks above the line. Each plot has eighteen data values. Upper plot is labeled Shipment 1.
Lower plot is labeled Shipment 2. Under each plot is the label Weight, in pounds. Upper plot data values are one x mark above sixteen, one x mark above seventeen, one x mark above eighteen, one x mark above nineteen, two x marks above twenty, three x marks above twenty-one, four x marks above twenty-two, three x marks above twenty-three, three x marks above twenty-four, and one x mark above twenty-five. Lower plot data values are one x mark above sixteen, two x marks above seventeen, three x marks above eighteen, four x marks above nineteen, three x marks above twenty, three x marks above twenty-one, two x marks above twenty-two, zero x mark above twenty-three, and one x mark above twenty-four.

A circle has a circumference of
3.14
3.143, point, 14 units.
What is the diameter of the circle?
Answer:
Hope this helps you
The diameter is 1 unit
Step-by-step explanation:
The circumference is 3.14 units
C = pi * d
Using 3.14 for pi
3.14 = 3.14 d
Divide each side by 3.14
3.14/3.14 = 3.14 d/ 3.14
1 =d

wanda reads 180 pages in 2 3/4 h. How many pages can she read in 5 1/2 h?
Answer:
are there any options? if not then i think it's 360 ( sorry if i'm wrong)
Answer:
360
Step-by-step explanation:
We find Wanda's reading speed in pager per hour, which is 180/2 3/4 = 180/2.75 = 65.4545...
To find how many pages she reads in 5 1/2 hours, multiply 65.4545... by 5 1/2, or 5.5 to get 360. She reads 360 pages in 5 1/2 hours

Valerie shares some of the 12 candies from this box.she gives her friend 1 candy for every 3 candies she eats herself. How many candies does she give to her friend?
Answer:
3
Step-by-step explanation:
Every group of candies eaten is 4 candies because Valerie eats 3 and her friend eats 1. 1+3 = 4 . 12/4 = 3
Step-by-step explanation:
1 : 3 = 4 <-- simplified ratio
x : y = 12 <-- trying to find the real ratio
12 ÷ 4 = 3 <-- find the unit rate
1 × 3 = 3 <-- find how much the friend has
So, her friend got 3 candies
Kim deposited $1,422 into a savings account. After 5 years, she had a total of $1,635.30 in her account. What is the interest rate?
With step by step explanation = Brainliest
Answer:
don't know
Step-by-step explanation:
ok please mark mr brainlist
Answer:
3%
Step-by-step explanation:
Interest rat is calculated by using the equation A = P(1 + r)^n
A is the amount after interest. Here, it is 1635.30
P is the principal, or base, amount. Here, it is 1422
r is the rate at which there is interest. It is what we need to find out.
n is the amount of years interest is calculated for. Here, it is 5
Now that we have everything, we calculate:
1635.30 = 1422(1 + r)^5
Now we have to get r on one side of the equation by itself:
Divide both sides by 1422:
1635.30/1422 = (1 + r)^5
5√(1655.30/1422) = 1 + r
5√(1.16406469) - 1 = r
Now r is on one side of the equation.
The 5th root of 1.16406469 is 1.03084987
1.03084987 - 1 = 0.0308, so it is 3%
The 5√ is the 5th root of the numbers
Or it's 2.835 percent I don't know

a florist orders sunflowers every 6 days, starting from the sixth day of the year, and daisies every 4 days starting from the fourth day of the year. when is the first THREE TIMES she will order the flowers on the same day?
Answer: 12th day
Step-by-step explanation:
Given , A florist orders sunflowers every 6 days and daisies every 4 days.
When it started from same day, then the next day she orders both kinds of flowers on the same day will be LCM (6,4), where LCM = Least Common Multiple.
Prime factorization:
6 = 2 x 3
4 = 2 x 2
LCM(6,4) = 2 x 2 x 3 = 12
Hence, she will order both kinds of flowers every 12 days.
