Answer:
53
Step-by-step explanation:
You need the perimeter, which is all sides added together
Answer:
53
Step-by-step explanation:
Perimeter= w+w+h+h
w=width
h=height
w=14.5
h=12
12+12=24
14.5+14.5=29
29+24=53
Given the function f(x)= -5x^{2} - x + 20, find f(3)
A line passes through (-2,5) and has slope 1/3. what is an equation of the line in point-slope form?
Answer:
y = 1 3 x + 13 3
Step-by-step explanation:
The equation of the line is
y = 1 3 x + 13 3
. To find other points on the line, simply plug in an x value, and solve for the corresponding y value.
Explanation:
To find other points on the line, we first have to find the equation for the line. We can easily use point-slope form:
y − y 1 = m ( x − x 1 )
y − 5 = 1 3 ( x 2 )
To put it in slope-intercept form, isolate y and simplify:
y= 1 3 ( x − 2 ) + 5
y = 1 3 x − 23 + 5
y = 1 3 x + 13 3
The Punnett square below shows the cross between two parents heterozygous for two traits. In horses, the allele for black color (B) is dominant over the allele for white color (b). Long hair (H) is
dominant over the short hair (h).
1. What are the genotype and phenotype of the offspring in block A, B, C, D, and E?
2. What is the probability of getting a black horse with short hair?
Genotype
Phenotype
A
B

See the attached table of genotypes.
A black horse with short hair has genotype Bxhh, where the x can be either B or b. According to the table, 3 of the 16 possible genotypes match this pattern, so the probability is 3/16.

what type of variation does the table represent?
Answer:
a
Step-by-step explanation:
its indirect cause the direct variation would be the y getting bigger with the x, but it's not. It's getting lower when the x is getting higher. hope this helps.

Henry has two same size rectangle divided into the same number of equal parts.one rectangle has 2/5 of the parts shaded,and the other has 1/2 of the parts shaded. Into how many parts could each rectangle be divided? show the work
Answer:
Ya
Step-by-step explanation:
Each rectangle can be divided into 10 parts.
What is fraction?A fraction is a part of a whole quantity.
In a fraction, the denominator represents the number of equal parts in a whole, and the numerator represents how many parts are being considered.
Given,
Same size rectangles are cut into same number of equal parts.
Shaded part on one rectangle = 2/5
Shaded part on other rectangle = 1/2
Denominator shows total parts of whole,
To get the same number of equal parts, we need to find
Least common multiple of the denominator
= 2 × 5 = 10
Hence, Into 10 parts, each rectangle should be divided.

A landscaping company placed two orders with a nursery. The first order was for 13 shrubs and 4 trees and totaled 487. The second order was for 6 scrubs and 2 trees,and totaled 232. The bills do not list the per-item price. What were the costs of one shrub of one tree?
Answer:
Cost of shrubs = 23
Cost of tree = 47
Step-by-step explanation:
Let
Cost of shrubs = x
Cost of tree = y
13x + 4y = 487 (1)
6x + 2y = 232 (2)
Multiply (2) by 2
12x + 4y = 464 (3)
13x + 4y = 487 (1)
Subtract (3) from (1)
13x - 12x = 487 - 464
x = 23
Substitute x = 23 into (2)
6x + 2y = 232 (2)
6(23) + 2y = 232
138 + 2y = 232
2y = 232 - 138
2y = 94
y = 94/2
= 47
y = 47

6x-1=-x+9
Answer:
x=10/7
Let's solve your equation step-by-step
6x−1=−x+9
Step 1: Add x to both sides
6x−1+x=−x+9+x
7x−1=9
Step 2: Add 1 to both sides
7x−1+1=9+1
7x=10
Step 3: Divide both sides by 7
7x/7=10/7
x=10/7
Answer:
x = 10 / 7
Step-by-step explanation:
6x - 1 = -x + 9
Add 1 to both sides of the equation.
6x - 1 = -x + 9
6x - 1 + 1 = -x + 9 + 1
Simplify
Add the numbers
6x - 1 + 1 = -x + 9 + 1
6x = -x + 9 + 1
Add the numbers
6x = -x + 9 + 1
6x = -x + 10
Add x to both sides of the equation.
6x = -x + 10
6x + x = -x + 10 + x
Simplify
Combine like terms
6x + x = -x + 10 + x
7x = -x + 10 + x
Combine like terms
7x = -x + 10 + x
7x = 10
Divide both sides of the equation by the same term
7x = 10
7x/7 = 10/7
Simplify
Cancel terms that are in both the numerator and denominator.
7x/7 = 10/7
x = 10/7
Solution
x = 10/7
I hope this helps have a great day!!!WILL MARK BRAINLIEST TO THE PERSON WITH THE BEST ANSWER!!! PLEASE ANSWER ALL QUESTIONS AND PLEASE SHOW FULL SOLUTIONS! PLEASE MAKE SURE YOU DID IT RIGHT. THANK YOU.
Answer:
1a) 67.2 kg
1b) 66.5 kg
1c) 64 kg, 68 kg
2a) Mean = 58.1m, Median = 55m, Mode = 49m
2b) The mode is not a good measure since all data except 49m appeared twice i.e. the data set is quite distributed. (sorry I am not very sure with this answer)
3a) Independent variable is time, Dependent variable is distance.
3b) See attachment.
3c) Linear
3d) 2.5s: 10m 6.25s: 25m 8s: 32m
3e) 3m: 0.75s 21m: 5.25s. 36m: 9s.
Step-by-step explanation:
1a) Mean = (74+71+68+84+54+60+64+68+65+64)/10 kg = 67.2 kg
1b) Sort the data in ascending order (in kg).
54 60 64 64 65 68 68 71 74 84
Median = (65+68)/2 kg = 66.5 kg
1c) Mode = 64 kg, 68 kg (both appeared twice)
2a) Mean = (45+52+47+55+62+80+71+60+84+57+46+50+48+61+49+63+54+49+72)/19 m = 58.1m (correct to 1 decimal place)
Arrange the data in ascending order (in m).
45 46 47 48 49 49 50 52 54 55 57 60 61 62 63 71 72 80 84
Median = 55m
Mode = 49m (appeared twice)
2b) See answer.
3a) Independent variable is the variable that is to be changed. Dependent variable is the variable that is to be measured.
3b) Just plot the graph.
3c) Distance = 4 x time
3d) 2.5 x 4 = 10m. 6.25 x 4 = 25m. 8 x 4 = 32m.
3e) 3/4=0.75s. 21/4=5.25s. 36/4=9s.
"what quadrant is...." PLEASE PLEASE HELP!!!! Thank you so so much!!! *will give brainliest*
Given:

To find:
The quadrant.
Solution:
We know that,
In I quadrant, all trigonometric ratios are positive.
In II quadrant, only [tex]\sin \theta, \text{cosec}\theta[/tex] are positive and others are negative.
In III quadrant, only [tex]\cot \theta, \tan\theta[/tex] are positive and others are negative.
In IV quadrant, only [tex]\cos \theta, \sec\theta[/tex] are positive and others are negative.
We have,
[tex]\tan \theta > 0[/tex] and [tex]\sec \theta <0[/tex].
Here, [tex]\tan \theta[/tex] is positive and [tex]\sec \theta[/tex] is negative. So, [tex]\theta [/tex] lies in the III quadrant.
Therefore, the correct option is C, i.e., III.

If "u" varies directly with "v", and u = 6 when v = -7, what is "u" when v =4?
Answer:
u = -24/7
Step-by-step explanation:
u = 6 = u
v -7 4
-7u = 24
u = -24/7
Answer:
u = - [tex]\frac{24}{7}[/tex]
Step-by-step explanation:
Given that u varies directly with v then the equation relating them is
u = kv ← k is the constant of variation
To find k use the condition u = 6 when v = - 7, then
6 = - 7k ( divide both sides by - 7 )
- [tex]\frac{6}{7}[/tex] = k
u = - [tex]\frac{6}{7}[/tex] v ← equation of variation
When v = 4 , then
u = - [tex]\frac{6}{7}[/tex] × 4 = - [tex]\frac{24}{7}[/tex]
Pedro drives the same route to work on Monday through Friday. His route includes one traffic light. According to the local traffic department, there is a 55% chance that the light will be red when he arrives at the intersection on a randomly selected workday. Suppose we choose 10 of Pedro's workdays at random and let Y = the number of times that the light is red.
Answer:
6 days
Step-by-step explanation:
Given
The proportion can be represented as:
[tex]p = 55\%[/tex]
And the number of days can be represented as:
[tex]n = 10[/tex]
Required
Determine the expected number of times, the light is red
To do this, we simply multiply the proportion by the number of days:
[tex]Y = n * p[/tex]
Substitute values for n and p
[tex]Y = 10 * 55\%[/tex]
Convert percentage to decimal
[tex]Y = 10 * 0.55[/tex]
[tex]Y = 5.5[/tex]
Approximate
[tex]Y = 6[/tex]
Hence, the expected number of days is 6 days
Show the different measuring instruments to be used in the economic/business system of the new civilization.
Answer:
The different measuring instruments to be used in the economic/business system of the new civilization is discussed below in detail.
Step-by-step explanation:
Economics is the research of how people allocate limited resources for generation, circulation, and consumption, both personally and collectively.
Two significant types of economics are microeconomics, which concentrates on the performance of individual customers and generators, and macroeconomics, which measures overall economies on a local, nationwide, or global scale.
Economics is especially concerned with performance in generation and exchange and practices models and opinions to assume how to generate incentives and procedures that will maximize productivity.
Economists formulate and announce numerous economic symbols, such as the Consumer Price Index (CPI). and gross domestic product (GDP).
Capitalism, communism, and socialism are examples of economic systems.
