The number of vegetable-bearing plants is 12/5.
How to find the number of vegetable-bearing plants?Lowes carries 3 types of plants.
1/10 of the plants are fruit bearing
1/2 of the plants are flower-bearing
The rest are vegetable-bearing plants.
Solution:
Let x be the no of vegetable-bearing plants.
The total number of plants = Number of plants that are fruit-bearing + Number of plants that are flower-bearing + Number of plants that are vegetable-bearing.
3 = 1/10+1/2+x
Taking L.C.M.,
3 = 1+5+10x/10
3 = 6+10x/10
30 = 6+10x
30-6 = 10x
24 = 10x
x = 12/5
Therefore, 12/5 of plants are vegetable-bearing.

Answer:
Step-by-step explanation:
Any buyer of a new sports car has to pick between 2 of 5 options for seat colors and 3 of 4 options for dashboard accessories. how many different combinations of colors and dashboard options are available to this buyer?
There are 40 different combinations of colors and dashboard options available to this buyer.
Combination is a counting technique where the order of the selected items from a collection does not matter. The formula in finding the number of combinations when ‘r’ items are chosen out of a total of ‘n’ objects.
nCr = n! / [r! (n - r)!]
If there are 2 of 5 options for seat colors, then using the formula, the number of combinations for the seat color is:
5C2 = 5! / [2! (5 - 2)!]
5C2 = 120 / 12
5C2 = 10
If there are 3 of 4 options for dashboard accessories, then using the formula, the number of combinations for the dashboard accessories is:
4C3 = 4! / [3! (4 - 3)!]
4C3 = 24 / 6
4C3 = 4
Multiplying the two results will give the total number of different combinations of colors and dashboard options available.

() A bookmark has an area of 160 square centimeters. Its perimeter is 56 centimeters.
What are the dimensions of the bookmark?
The dimensions of the bookmark is 14cm.
What is area and perimeter of square?The perimeter of a shape is the space surrounding it. Space inside a shape is measured by area. Learn how to compute the area and perimeter of various forms. The perimeter of a square is equal to four times the length of its side, and its area is equal to the square of that length. As a result, the square's perimeter will be as follows: perimeter = 4 x side = 4 area units. As a result, given a square's size, we can determine its perimeter.
Given data
Area = 160cm
Perimeter = 56
Area = side²
Perimeter = 4(a)
Putting values in perimeter

What is the probability that María Fernanda reaches in the bag and randomly selects 2 chocolate chip cookies from the bag?
Based on the number of cookies in the bag of cookies, if María Fernanda is to reach in and select 2 chocolate chip cookies, the probability of that happening is 6.46%
How to find the probability?The events that María Fernanda picks one chocolate chip cookie and then another, are both independent events.
To find the probability of independent events, the formula is:
= Independent event probability 1 x Independent probability 2
Find the total number of cookies:
= 7 chocolate chip cookies + 5 peanut butter cookies + 6 sugar cookies + 8 oatmeal cookies
= 26 cookies
The probability of two chocolate cookies being picked by María Fernanda is:
= Number of chocolate cookies / Number of total chips x Number of chocolate cookies left / Number of cookies left

For each event, write the sample space and tell how many outcomes there are. Roll a standard number cube. Then flip a quarter. How many outcomes are there?
The total number of outcomes is 12.
An outcome is a potential outcome of an experiment or trial in probability theory.
Each conceivable result of a specific experiment is distinct, and many results are incompatible (only one outcome will occur on each trial of the experiment). The components of a sample space are all the potential results of an experiment. There is a chance that outcomes will occur with probabilities between 0 and 1. (inclusively). In a discrete probability distribution whose sample space is finite, each result is assigned a certain probability. A continuous distribution, on the other hand, only allows non-zero probabilities to be assigned to ranges of events, with all individual outcomes having zero probability.When a number cube is rolled there are 6 distinct outcomes {1,2,3,4,5,6} = 6
Again when a quarter is flipped then there are two possible outcomes {heads , tails } = 2
The total number of outcomes = 6 × 2 = 12
Hence there are 12 distinct outcomes.

Phyllis invested $9,500 a portion earning a simple interest rate of 7 1/5% per year and the rest earning a rate of 7% per year. After 1 year the total interest earned on these investments was $677. How much money did she invest at each rate?
Using simple interest, it is found that the amounts invested are given as follows:
$2,350 at a rate of 7.2%.$6,650 at a rate of 7%.Simple InterestSimple interest is used when there is a single compounding per time period, usually measured in years.
The amount of money after t years in is modeled by:
A(t) = P(1 + rt)
In which:
P is the initial amount of the investment.r is the interest rate of the investment, as a decimal.The interest accrued over t years is:
I(t) = Prt.
For this problem, we have that:
She had two investments totaling $9500, hence P and 9500 - P.The rates are of [tex]r_1 = 0.072, r_2 = 0.07[/tex].From the interest earned, we have that:
[tex]I_1 + I_2 = 677[/tex]
In which:
[tex]I_1 = 0.072P[/tex][tex]I_2 = 0.07(9000 - P)[/tex]Replacing both these relations in the sum of interests, we have that:
0.072P + 0.07(9000 - P) = 677
0.002P = 677 - 0.07(9000)
P = (677 - 0.07(9000))/0.02
P = 2350.
Hence she invested $2,350 at a rate of 7.2% and $6,650 at a rate of 7%, as 9000 - 2350 = 6650.

What is meant by decibel?The decibel (dB) is 10 times the decimal logarithm of the ratio of two variables' values. Decibels are calculated using a logarithm, which allows very large or very small relationships to be represented with a conveniently small number. The decibel, abbreviated dB, is the scale's unit. Sound intensity as a reference ( = 10 ^{ -12 } Watts per square meter.) The decibel (dB) is a logarithmic unit of measurement for sound level. It is also widely used in electronics, communications, and signals. The dB is a logarithmic measure of a ratio. Power, sound pressure, voltage, or intensity are all examples of ratios.A noise or sound level of 85 decibels is equivalent to that of a food blender, heavy traffic while driving, a noisy restaurant, or a movie theater.

We have to find the following products of the equations.
The basic rule for multiplication between numbers with decimal points can be described through some examples first.
Decimal point is shifted leftwards up to the power of 10 which is divided with it. Also decimal point is shifted rightwards when multiplied with powers of 10.
Now we will find the product for each equation:
For 476 × 0.001, 0.001 = 1/1000
Therefore, 476 × 0.001 = 476 × 1/1000 = 0.476 [decimal point shifted left]
For 0.476 × 10¹ = 0.476 × 10 = 4.76 [decimal point shifted right]

1. First we expand the brackets
10x-20x=10x-8
2. we can simplify the equation to
-10x=10x-8
3. we want to find the value of x so we get all of the x on one side so we would -10x on both side
-20x=-8
4. to find the value of x we divide each side by -20 this gives us
x=[tex]\frac{8}{20}[/tex]
(it's not a negative as the negative cancel each other out as negative divided by negative gives us positive)
5. However we can simplify the fraction by dividing the top and bottom by 4 (this is because the highest common factor for both number is 4) this gives
