Emmet walks 0.4 miles on each trip to the park. How far will Emmet walk if he makes 4 trips to the park?
Miles
Emmet will walk 1. 6 miles if he makes 4 trips to the park
How to determine the valueFrom the information given, we have that;
Emmy walks 0. 4 miles per tripHe wants to walk 4 tripsIt is important to note that proportion is the mathematical comparison of two numbers or elements
If 0. 4 miles is equivalent to 1 trip
Then x miles is equivalent to 4 trips
cross multiply
x = 0 . 4 × 4
Multiply through
x = 1. 6 miles
Thus, Emmet will walk 1. 6 miles if he makes 4 trips to the park

√4x + 8= x+ 3
Answer:
X=-5
Step-by-step explanation:
√4x+8=x+3
Simplifies to:
2x+8=x+3
Let's solve your equation step-by-step.
2x+8=x+3
Step 1: Subtract x from both sides.
2x+8−x=x+3−x
x+8=3
Step 2: Subtract 8 from both sides.
x+8−8=3−8

Step 1: Define
v² = u² + 2as
v = 5
u = 2
s = 7
Step 2: Evaluate
Subtract u² on both sides: v² - u² = 2asDivide 2s on both sides: (v² - u²)/(2s) = aRewrite: a = (v² - u²)/(2s)Substitute: a = (5² - 2²)/(2 · 7)Exponents: a = (25 - 4)/(2 · 7)Multiply: a = (25 - 4)/14Subtract: a = 21/14Simplify: a = 3/2After a discount of 40%, the sale price of a ridepass at a fun park is $30 what was the orginal price
determine the slope of the lines.
line 1: y=9
line 2: x=-3
are the slopes parallel, perpendicular, or neither?
4r + 5y = 10
- 1 - 8 = 3y
Answer:
y = -3, r = 25/4
Step-by-step explanation:
4r+5y = 10
-1 - 8 = 3y <--- This can be simplified to:
-9 = 3y
-3 = y
Now we plug -3 into y in the first equation
4r + 5y = 10
4r + 5(-3) = 10
4r - 15 = 10
4r = 25
r = 25/4
Troy invests $540 in a savings account that earns a simple interest
rate of 2.3% annually. How much money will Troy have in
the account after four years assuming he does not deposit or
withdraw any money?
please help:)
wish i could help bro bro.
Answer/step-by-step explanation:
Well, we first need to find out what 2.3 of $540 is.
540 x 2.3 = 1,242.
Now, we need to find what the yearly interest rate is over the course of four years.
1,242 x 4 = $4,968.
Therefore, Trey will have earned $4,968 after four years.
To complete this problem, we need to add this to his original balance, or $540.
4,968 + 540 = 5,508
Therefore, Trey would make a total of $5,508 after four years.

420 presents in 15 hours at this rate how many presents does Santa deliver in 5 hours
Answer:
140 Presenrs
Step-by-step explanation:
If Santa delivers 420 presents in 15 hours and to get to 5 hours you need to divide 15 to 3, so what you do to one number you must do to the other, so therefore divide 420 by 3 to get 140 presents in 5 hours.

find the equation of a circle with a center at (-1, 5) and a point on the circle is (4, 4). ( x 1) 2 ( y - 5) 2
The equation of a circle is x² + y²+ 2x - 10y = 0 with a center at (-1, 5).
What is the equation of a circle?The equation of a circle with center (h,k) and radius r is :
r² = (x−h)² + (y−k)²
Given that a circle with a center at (-1, 5) and a point on the circle is (4, 4).
Since the circle passes through points (4, 4),
So the radius (r) of the circle is the distance between points (-1, 5) and (4, 4).
⇒ r² = (-1−4)² + (5−4)² = 25 + 1
⇒ r = √26
The center of the circle is given as (h,k) = (-1, 5)
So the equation of the circle is
⇒ r² = (x − h)² + (y − k)²
Substitute the values of r, h, and k in the above equation,
⇒ 26 = (x − (-1))² + (y −5)²
⇒ 26 = (x + 1)² + (y −5)²
⇒ 26 = x² + 2x +1 + y² - 10y + 25
⇒ x² + y²+ 2x - 10y = 0
Hence, the equation of a circle is x² + y²+ 2x - 10y = 0 with a center at (-1, 5).

Answer:
Line 1 and Line 2: Perpendicular
Line 1 and Line 3: Neither
Line 2 and Line 3: Neither
Step-by-step explanation:
We will write all lines in slope intercept form i.e [tex]y=mx+b[/tex]
where m is slope.
And check
a) If two lines are parallel they have same slope [tex]m_1=m_2[/tex]
b) If two lines are perpendicular they have opposite reciprocal slopes i.e [tex]m_1=-\frac{1}{m_2}[/tex]
Equation for Line 1: [tex]y=-\frac{4}{3}x-4[/tex]
Already in slope-intercept form
Slope for Line 1 m is: [tex]\mathbf{m_1=-\frac{4}{3}}[/tex]
Equation for Line 2: [tex]6x-8y=-6[/tex]
Converting into slope-intercept form:
[tex]6x-8y=-6\\-8y=-6x-6\\y=\frac{-6x-6}{-8}\\y=\frac{-6x}{-8}+\frac{-6}{-8} \\y=\frac{3x}{4}+\frac{3}{4}[/tex]
Slope for Line 2 m is: [tex]\mathbf{m_2=\frac{3}{4}}[/tex]
Equation for Line 3: [tex]-4y=3x+7[/tex]
Converting into slope-intercept form:
[tex]-4y=3x+7\\y=-\frac{3}{4} -\frac{7}{4}[/tex]
Slope for Line 3 m is: [tex]\mathbf{m_3=-\frac{3}{4}}[/tex]
Now, finding answers
Line 1 and Line 2
Checking their slopes: [tex]\mathbf{m_1=-\frac{4}{3}}[/tex], [tex]\mathbf{m_2=\frac{3}{4}}[/tex]
Both lines are perpendicular because they have opposite reciprocal slopes
Line 1 and Line 3
Checking their slopes: [tex]\mathbf{m_1=-\frac{4}{3}}[/tex], [tex]\mathbf{m_3=-\frac{3}{4}}[/tex]
Slopes are neither same, nor opposite reciprocal, so they are neither
Line 2 and Line 3
Checking their slopes: [tex]\mathbf{m_2=\frac{3}{4}}[/tex], [tex]\mathbf{m_3=-\frac{3}{4}}[/tex]
Slopes are neither same, nor opposite reciprocal, so they are neither
The answers are:
Line 1 and Line 2: Perpendicular
Line 1 and Line 3: Neither
Line 2 and Line 3: Neither
