As part of Kayla's exercise program, she either runs 6 miles/day or rides her bike 10 miles/day. Her new goal is to cover a mini

lawyer [4039]

To find out the number of days, we should create equations based on the values provided. The total distance Kayla aims to travel combines both her running distance and her biking distance.

200 miles = (6 miles/day)x + (10 miles/day)y

where x signifies the days she spent running and y represents the days bike riding.

If the minimum biking days are set to be 15, indicated by y = 15, we have:

200 miles = (6 miles/day)x + (10 miles/day)(15 days)

Solving for x gives:
200 = 6x + 150
50 = 6x
x = 8.3333 days

Total days = 15 days biking + 8.3333 days running = 23.3333 days, approximately making it 24 days.

Marc mows lawns for $25 each lawn, plus $5 for every hour he spends mowing. The equation for his total earnings per lawn is y =

tester [3938]

Answer:

The constant pay of $25 signifies the intercept

Step-by-step explanation:

To address this query, we first need to comprehend and relate it to the formula for a straight line.

i.e $y= mx+c$ this represents the line's equation

where m= slope

y= dependent variable

x= independent variable

c= intercept

Given

$y= 25+5h$

by comparing the two expressions, we can observe that

25 is equivalent to c, which denotes the intercept

Value of sec Square 26 degrees - cot square 64 degrees is

Leona [4187]

Answer:

The value equals 1

Step-by-step explanation:

Consider the expression

$sec^{2}(26\°)-cot^2(64\°)$

Recall that

$cot^2(64\°)=\frac{cos^2(64\°)}{sin^2(64\°)}$

$sec^{2}(26\°)=\frac{1}{cos^2(26\°)}$

For two complementary angles A and B (where A+B=90°),

the identity is

cos(A) = sin(B)

Here, 26° and 64° are complementary angles, so

$\frac{1}{cos^2(26\°)}=\frac{1}{sin^2(64\°)}$

Substituting values,

$\frac{1}{sin^2(64\°)}-\frac{cos^2(64\°)}{sin^2(64\°)}$

$\frac{1-cos^2(64\°)}{sin^2(64\°)}$

From this, we find

$1-cos^2(64\°)=sin^2(64\°)$

By substitution,

$\frac{sin^2(64\°)}{sin^2(64\°)}=1$

A tank contains 24 gallons of water when all of a sudden the water begins draining at a constant rate of 2 gallons per hour. Let

AnnZ [3900]

Response:

a) $V(t) = 24 - 2t$

b) From t increasing from 3 to 6, v changes from 18 gallons to 12 gallons.

Detailed explanation:

The relationship between the tank’s volume and time is given by:

$V(t) = V(0) - at$

Where V(0) indicates the starting volume and a denotes the hourly decrease.

a. Create a formula for v in terms of t.

The tank starts with 24 gallons of water, hence $V(0) = 24$

It drains steadily at 2 gallons each hour, therefore $a = 2$

Then

$V(t) = V(0) - at$

$V(t) = 24 - 2t$

b. When t progresses from 3 to 6, v changes from _________ to _________

$V(t) = 24 - 2t$

$V(3) = 24 - 2*3 = 18$

$V(6) = 24 - 2*6 = 12$

So as t progresses from 3 to 6, v shifts from 18 gallons to 12 gallons.
