the problem is the image (How is everyone day)
Answer:
casey has the faster rate
Step-by-step explanation:
first multiply jessicas race distance and time by 2
30 * 2
= 60
5 * 2
= 10
we did that so both jessicas time and caseys time was the same, making it easier to solve ( also by this point we already know who has the faster rate )
now we are going to divide both of their times and distances by 5
casey
10/5
= 2
45/5
= 9
jessica
10/5
= 2
60/5
12
the step is to divide their times/distances once again but this time by 2
casey
2/1
= 1
9/2
= 4.5
jessica
2/1
= 1
12/2
= 6
and our answer is 4.5 or casey !
4.5 > 6
hope this helps you! :)
Please help me with this !
Answer:
a. 4 (or maybe like 3.5)
b. 6
Step-by-step explanation:
a. Going from x = 0 to x = 8, it is obvious that y goes down 4 or 4.5 units during this stretch. This gives an approximate slope of -3/8. With this in mind, it can be easily calculated that going the remaining distance from x = 8 to x = 10, the value of y will be approximately 4 or so.
b. A dot literally is right next to (6, 6).
Sophia cut a piece of wood that measured 10.2inches but she was supposed to cut 16 inches what is the percent error
Answer: 35.80 %
Step-by-step explanation:
Given
Sophia mistakenly cut 10.2 inches
The actual cut should be 16 inches
[tex]\Rightarrow \% \text{error}=\dfrac{\text{Actual dimension-Faulty dimension}}{\text{Actual dimension}}\times 100\\\\\Rightarrow \% \text{error}=\dfrac{16-10.2}{16.2}\times 100=35.80\%[/tex]
Select all the expressions that are equivalent to
1/2(2).
Z+Z
Z/2
Z/Z
1/4 (z)+1/4 (z)
2(z)
Answer:
Step-by-step explanation:
An ellipse is defined as the locus of all points,the sum of whose from two given points is constant. Here z is a complex number whose distance from (1,0) and (−1,0) is constant. Hence the locus of z is an ellipse in the complex plane. Hence z will be all those points which lies on the ellipse with focus (−1,0) and (1,0).
What are the roots of the equation 2x2 - 6x + 3 = 0?
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
The given possible roots have the form that we'd get by using the quadratic formula, so let's start with that. Here the coefficients are {2, -6, 3}, and so the discriminant (b^2 - 4ac) is (-6)^2 - 4(2)(3), or 36 - 24 = 12.
Because the discriminant is positive we know immediately that there are two different real roots.
-(-6) ± √12 6 ± √12

A father left 280 acres of land to be divided among his sons Al and Bob in the ratio 4:3, respectively. How many acres should Al receive?
Answer:
160 acres
Step-by-step explanation:
Given data
Total Amount of land= 280 Acres
Ratio=4:3
Total part = 4+3= 7
Applying the part to all method
let AI receive x acres
Then
4/7= x/280
cross multiply
7x= 280*4
7x=1120
x= 1120/7
x= 160
Hence AI will receive 160 acres
