Answer: 3.33 miles per hour.
Step-by-step explanation: To find the speed of the second runner, we can assume their speed is x miles per hour. Using the fact that the first runner's speed is 4/5 of the second runner's speed, we can set up the equation x - 0.4x = 2 to solve for x.
Solving for x, we get x = 3.33 miles per hour.
Sophia's mom spent on party bags and ice cream for her birthday party.
Each ice cream costs 2 cents, and each party bag cost $1.50.
Write an equation that represents the relationship between the number of ice creams she bought, i, and the number of party bags she bought, b
Answer & Step-by-step explanation:
i = 2
b = 150
---------------------------------------------------------------------------------------------------------------
The equations:
i= b-148
or
b= i+148
or
b-i = 148
I am not really sure which equation you want, but I hope this helps!!!

Explain the law of Syllogism.
The law of syllogism, also called reasoning by transitivity, is a valid argument form of deductive reasoning that follows a set pattern. It is similar to the transitive property of equality, which reads: if a = b and b = c then, a = c. ... If they are true, then statement 3 must be the valid conclusion.Answer:

the graphs of f(x) and g(x)= f(x)+k are shown below. the value of k is ____
Answer:
The value of k is 2
Step-by-step explanation:
The rule of vertical translation
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k ⇒ add y-coordinate of every point by kIf the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k ⇒ subtract y-coordinate of every point by kFrom the graph
∵ Point (0, 0) ∈ f(x)
∵ Point (0, 2) ∈ g(x)
∵ Point (2, 4) ∈ f(x)
∵ Point (2, 6) ∈ g(x)
∴ Each y-coordinates of the points on f(x) added by 2 on g(x)
→ That means f(x) is translated up 2 units
∴ f(x) is translated up by 2 units
→ By using the first rule above
∴ g(x) = f(x) + 2
∵ g(x) = f(x) + k
∴ k = 2
∴ The value of k is 2
If you bought a stock last year for a price of $90, and it has gone down 13% since then, how much is the stock worth now, to the nearest cent?
Answer:
It is now $109.62. You would multiply .13 (13%) by 126 which would give you 16.38. You would then subtract 126-16.38 to get 109.62.
Hope this helps, have a great day, have a wonderful weekend and stay safe!
Also Happy Halloween! :) :D :3
Answer:
$78.30
Step-by-step explanation:
13% of 90 is 11.7, 90 - 11.7 = 78.3, therefore our answer is $78.30

Help ASAP!! Find The Measure Of The indicated Angle In The Diagram.
Answer:
136 :)
Step-by-step explanation:
112 + 24 = 135
180 - 136 = 44
180 - 44 = 136
Answer:
Step-by-step explanation:You know that all angles in a triangle add to 180 degrees. So you do:
112+24= 136
Then,
180-136= 44
44 is the angle ont the other side of the question mark. So we know that 44 and the unkown angle add to 180, So,
180-44= 136
So the unknown angle is 36.

What is the image point of (-6,9)(−6,9) after a translation left 4 units and down 1 unit?
Answer:
( -10,8)
Step-by-step explanation:
(-6,9)
Shifting 4 units left means subtract 4 from the x coordinate
(-6-4,9)
Shifting 1 unit down means subtract 1 from the y coordiant
(-6-4,9-1)
( -10,8)
Answer:
(-10, 8)
Step-by-step explanation:
A translation left 4 units and down 1 unit would be described algebraically as:
[tex](x,y)\rightarrow(x-4,y-1)[/tex]
Apply rule to (-6,9):
[tex](-6,9)\rightarrow(-6-4,9-1)\rightarrow(-10,8)[/tex]
The image after the translation should be (-10, 8).
Hope this helps.
The height h in feet of an object t seconds after it is dropped can be modeled by the quadratic equation h=-16t^2+h0, where h0 is the initial height of the object. Solve the equation h=-16t^2+255 for t, using the quadratic formula to determine the time it takes the rock to reach the canyon floor.
Answer:
The rock will take approximately 3.992 seconds to reach the canyon floor.
Step-by-step explanation:
For all [tex]a\cdot t^{2}+b\cdot t + c = 0[/tex], its roots are determined by the Quadratic Formula:
[tex]t = \frac{-b\pm\sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex]
In this case, it corresponds to instants when rock is either launched or hits the floor. If we know that [tex]a = -16[/tex], [tex]b = 0[/tex] and [tex]c = 255[/tex], the time it takes the rock to reach the canyon floor is:
[tex]t = \frac{-0\pm\sqrt{(0)^{2}-4\cdot (-16)\cdot (255)}}{2\cdot (-16)}[/tex]
[tex]t \approx 3.992\,s[/tex]
The rock will take approximately 3.992 seconds to reach the canyon floor.

Given f(x) = -3x – 1, solve for x when f(x) = -10
(Will mark brainliest)
Answer:
x=3
Step-by-step explanation:
f(x) = -3x – 1
Let f(x) = -10
-10 = -3x-1
Add 1 to each side
-10+1= -3x-1+1
-9 = -3x
Divide each side by -3
-9/-3 = -3x/-3
3 = x

A roller skating offers a special rate for birthday parties. On the same day, a party for 10 skates cost $107 and a party for 15 skaters cost $137.
A) write a linear equation in point-slope form.
B) Find the cost of 12 skaters.
Answer:
128
Step-by-step explanation:
137-107/15-10
M=7.4 or 7
Equation using (10,107)
Y-107=7(x-10)
Substitute 12 for x
Y-107=7(12-9)
Simplify the right side
Y-107 = 21
Solve for y
Y-107+107= 21+107
Y=128
A party For 12 skaters would cost $128

The number number line it is seven units apart.
The absolute value larger number smaller number would be 2 - (-5). So what you do with that is keep the 2 change the subtraction sign to plus sign and change the negative 5 to positive 5. So your answer would be 7.
And smaller number to larger number would be -5 - 2. And then you do the same steps as the last one. Keep the negative five, change the subtraction sign to addition sign and make the two negative. And that answer would be -7
2. For the number two problem you would plot the robins nest just below the top of the verticle line. the red squirrel den would be right next to the zero but a tad up. And the groundhog burrow would be below the zero mark and a little before the end of the verticle line.
Next, for groundhog burrow to red squirrel den you put the number 0.3-(-1.2)=1.5 Red squirrel den to Robin’s nest 3.6 – 0.3 = 3.3. And for the last one Groundhog burrow to Robin’s nest 3.6 – (-1.2) = 4.8.
3. you have to turn the 1 1/2 and 3/4 into 8ths. 1/2= 3*4 = 12 and for the denominator 2*4 = 8. So 12/8.
The next one is 3*2 which is 6 and 4*2=8
so now you have 12/8, 6/8, and 1/8
you have to add the points on the chart (i cant really help you on this part because i do not know how to upload picture) but you would make 24 and then you find where 12/8 would go and draw the hops but on mine the hop looks like how you would draw a rainbow but just one for the 12. Then do the same for the 6 and add 1 for the last one to make 19.
On mine I add the 12 + 6 + 1 = 19 so that is how i got mine. (sry if this a bad explination)
it should kinda look like this on the chart.
| | | | | | | | | | | | | | | | | | | | | | | | they should be spaced apart like this.
and for the last one i put cup 3 because it bigger than the amount of ingrident in the recipe. (im not sure if that one was the answer this is the only part we didnt get help on in class)
Step-by-step explanation:
Method B
(Step 1) | 19 - (-12) |
(Step 2) | 19 + 12|
(Step 3) | 31 | = 31
