Answer:
3mph
Step-by-step explanation:
Depending how far you're traveling and how fast you traveled. When doing speed you typically do it by hours and the unit will be miles per hour (mph).
1. 1.5 mi=0.5 hr
2. Multiple 0.5 by 2 to get one hour, and do the same to the other side
2(1.5)=2(0.5)
3. 3mi=1hr
4. The answer is 3mph
Find the equation of the line that is perpendicualr to the line y=1/5x-4 and that contains the point (1,1).
‼️ASAP!!! BRAINLIEST!!‼️
PLS HELP!!! SHOW ALL WORK + STEPS!! Thx!
Answer:
Option A
Step-by-step explanation:
to be perpendicular, the product of two slopes should be -1
the slope of the first equation is 1/5, so the slope should be -5
(1/5) (-5)= -1
y= -5x +b
Substitute (1,1) to solve for b,
b= 6
Thus, the equation is y= -5x +6

u have to multiply both of the numbers
for each sequence,find the first 4 terms and the 10th term.
a)3n+4
b)4n-5
Answer:
i know a good trick on how to do this.
Step-by-step explanation:
The number 4 is apart of the sequence, but it has been taken away by 3.
3+4=7. Since it was taken away by 3, we have to add 7 by 3 to get 9. So on and so forth.
jose flies a kite 17 1/2 ft above the ground. he increases its elevation by 4 3/4 ft by letting out some string. then he reels in the string and changes its elevation by -15.8 ft. after jose reels in the string, what is the kite's elevation relative to the ground? show your work
Answer:
6.45 feet
Step-by-step explanation:
He starts 17 and 1/2 feet off the ground
Elevation relative to ground: 17 1/2
Then he increases the height by 4 and 3/4
Expression: 17 1/2 +4 3/4
Elevation relative to ground: 22 1/4
Next he decreases the elevation by 15.8 feet
Expression: 22.25-15.8
Elevation relative to ground: 6.45
The answer 6.45 feet from the ground

When Charlotte left her house this morning, her cell phone was 30% charged and it
then started to lose 2.5% charge for each hour thereafter. Write an equation for B, in
terms of t, representing the charge remaining in Charlotte's battery, as a percentage,
t hours after Charlotte left her house.
Answer:
B = 32.5 - 2.5tStep-by-step explanation:
Let the initial percentage to be 30%
If it started to loose 2.5% every hour where;
t represents the time after Charlotte left her house
The amount of percent remaining every hour will form an arithmetic sequence as shown;
30, (30-2.5), (30-5.0),...
30, 27.5, 25.0...
Using the nth term for calculating an arithmetic sequence
B = a + (t-1)d
a is the first term = 30
d is the common difference = 27.5-30 = 25-27.5 = -2.5
t is the time
Substitute the given values into the formula;
B = 30 + (t-1)(-2.5)
B = 30+(-2.5t+2.5)
B = 30-2.5t+2.5
B = 32.5 - 2.5t
Hence equation for B, in terms of t, representing the charge remaining in Charlotte's battery, as a percentage, t hours after Charlotte left her house is B = 32.5 - 2.5t

What are the four types of slope
Answer:
Negative, positive, 0, undefined
Step-by-step explanation:
A negative slope is when a line is going down from left to right. A positive slope is when a line is going up from left to right. A slope of 0 is a horizontal line and an undefined slope is a vertical line. Hope this helps!

Answer:
$6.00
Explanation:
10% of 200 is 20
20/30 = $.6666
Each parent gets $0.67 off.
$200/30 = $6.6666
$6.6666 ---> $6.67
6.67 - 0.67
= 6.00
Check:
6.00 * 30 = 180
200-180 = 20
Consider Brainliest! Hope I helped!
Answer:
Each parent pays an amount of £6.
Step-by-step explanation:
Cost of the hall = £200
Discount for parents = 10%
Cost of the hall for parents
= 200 - 10% of 200
= 200 - 10/100 × 200
= 200 - 10 × 2
= 200 - 20
= £180
If 30 parents share the cost equally,
Each parent has to pay
180/30
= 18/3
= 6
6. Consider the inequality 12<-3 (x + 4). Which value of x is part of the solution set of this inequality?
Answer:
-8
Step-by-step explanation:
12<-3 (x + 4)
1. distribute to the -3 to the x and 4 and should get
-3*x = -3x
-3*4 = -12
12< -3x - 12
2. now you get rid of the common factors which is -12 so add 12 to both sides and should get
-12+12=0
12+12=24
24< -3x
3. to get x by itself you will have to get rid of -3, so how to do that is divide -3 to both side and should get
-3x/-3= x
24/-3= -8
-8<x
The diagram shows a periscope used to see objects that are behind or under a barrier. What makes it possible to see an object when looking through a periscope? The periscope –
A. contains mirrors that reflect the object
B. magnifies small objects so they can be seen
C. absorbs the light rays passing through it
D. separates the light into different colors
Answer: A. contains mirrors that reflect the object
Step-by-step explanation:
A periscope contains mirrors in it that are on opposite sides and are arranged in a 45° angle to each other. It works by light striking the first mirror which cause its to reflect it at a 45° angle to the next mirror.
Depending on the length of the periscope, this continues until the last mirror reflects the incoming light to the eyes of the person using the periscope thereby allowing them to see objects hidden behind or under a barrier.

Adventureland plans on updating the Arcade with some new and improved games.
They plan on purchasing a new Air hockey table for $875.23, a pinball machine for
$622.19, and two arcade racing games for $942.49 each. What is the total cost for the
new games including an 8.75% sales tax? I will give brainiest
Answer: $3678.36
Step-by-step explanation:
New airball hockey table = $875.23
pinball machine = $622.19
2 arcade racing games = $942.49 each.= $942.49 × 2 = $1884.98
Total amount without sales tax will be:
= $875.23 + $622.19 + $1884.98
= $3382.4
Sales tax = 8.75% × $3382.4
= 0.0875 × $3382.4
= $295.96
Total cost = $3382.40 + $295.96
= $3678.36

What is the equation of this graphed line
Answer:
y=2x+2
Step-by-step explanation:
Use the method rise overrun from 0,2 to 2,6 it rises 4 and runs 2(moves positively on the x-axis). divide 4 by 2 and get 2.
then check the y-intercept( when x is 0 on y-axis) the y intercept is 2
then plug in y=slope(x)+b(intercept)
to get y=2x+2.
The Carey family took a trip in November. Mary is calculating the gas mileage in miles per gallon for her dad's truck. When he fills the tank, her dad records the miles on the truck as 15,345. Her dad pays $53.28 to fill up the empty gas tank of the truck. What is the size of the truck's tank in gallons if it cost $3.33 per gallon? Round your answer to the nearest whole number. Be sure to include the correct units in your final answer. *
Answer:
The size of the tank is 16 gallons
Step-by-step explanation:
Here, we want to calculate the size of the gas tank of the truck
we simply divide the total amount spent by the price per gallon

RootIndex 3 StartRoot StartFraction x cubed Over c y Superscript 4 Baseline EndFraction EndRoot = StartFraction x Over 4 y (RootIndex 3 StartRoot y EndRoot) EndFraction
Answer:
C. c = 64
Step-by-step explanation:
The question is incomplete. Here is the complete question.
What value of c makes the equation true? Assume x greater-than 0 and y greater-than 0
RootIndex 3 StartRoot StartFraction x cubed Over c y Superscript 4 Baseline EndFraction EndRoot = StartFraction x Over 4 y (RootIndex 3 StartRoot y EndRoot) EndFraction
c = 12
c = 16
c = 64
c = 81
Given the function;
[tex]\sqrt[3]{\dfrac{x^3}{cy^4} } = \dfrac{x}{4y\sqrt[3]{y} }[/tex]
We are to find the value of c from the expression.
Step 1: Take the cube of both sides;
[tex](\sqrt[3]{\dfrac{x^3}{cy^4} } )^3= (\dfrac{x}{4y\sqrt[3]{y} })^3\\\dfrac{x^3}{cy^4} = \dfrac{x^3}{(4y)^3(\sqrt[3]{y} )^3}\\\dfrac{x^3}{cy^4} = \dfrac{x^3}{(64y^3)(y)}\\\\\dfrac{x^3}{cy^4} = \dfrac{x^3}{64y^4}\\[/tex]
Step 2: compare the denominator of both sides of the equation;
[tex]\dfrac{x^3}{cy^4} = \dfrac{x^3}{64y^4}\\\\On \ comparing;\\\\cy^4 = 64y^4\\[/tex]
Step 3: Divide both sides by y₄
[tex]\dfrac{cy^4}{y^4} = \dfrac{64y^4}{y^4}\\c = 64\\[/tex]
Hence the value of c is 64. Option C is correct

A pitcher can hold 5.2 liters of water. How many 0.4 liter glasses of water can be poured from the pitcher? *
13 glasses can be poured
Hope I helped
Answer:
13
Step-by-step explanation:
number of glasses = total quantity of water / quantity of one cup
n = 5.2/0.4
n = 52/4 (multiply numerator and denominator with 10)
n = 13
therefore it can be poured into 13 cups
