in new Mexico the sales tax rate is 5.125% .the price tag on a baby crib gives the price as 320$ .what is the total cost for the crib including sales tax , in new mexico
Answer:
Total cost of the crib = $336.40
Step-by-step explanation:
Total Cost of the crib = Cost of the crib + (cost of the crib × Sale tax%)
Total Cost of the crib = $320 + ($320 × .05125) 5.125% = .05125 as a
decimal.
Total cost of the crib = $320 + $16.40
Total cost of the crib = $336.40

1. Isosceles triangles have two sides equal to each other. If the unequal side is 40 degrees and there are 180 degrees in a triangle, 180-40=140/2=70 degrees for the other two sides.
2. Same explanation as 1.
3. Equilateral triangles all have the same degrees. If 60 is the degree for one angle, it is the degree for the other two as well.
4. Same explanation as 1.
5. All side length of an equilateral triangle are the same. If the side length of one side is 10, the other two sides are 10 too.
6. Same explanation as 5, but with 6 as the side length.
7. It is an isosceles triangle and two sides are equal. Since one side is 12 and the other side is the second of the equal sides, the side length would be 12
8. Same explanation as 7, but with 9 as the side length.
9. 180-46=134-46(other side length)=88 (remaining side length)
10. 2x+2+2x+2+3x+1=7x+5. 7x+5=180. 180-5=175. 175/7=25. 3(25)+1=76.

The volume of a rectangular solid is 540 cubic feet.
The width is 3 feet more than the height, and the
length is 4 more feet than the height. Find the
dimensions of the solid.
Answer:
l = 32.57, w = 24.43, h = 8.14
Step-by-step explanation:
volume = l*w*h
l = 4x
w = 3x
h = x
540 = 4x * 3x * x
540 = 12x^3
[tex]\sqrt[3]{540}[/tex] = 8.14
l = 4x = 4(8.14) = 32.57
w = 3x = 3(8.14) = 24.43
h = x = 8.14
hope it helps :)

Answer:
y = 2x + 2
Step-by-step explanation:
y = mx + b
[] m is slope
[] b is y-intercept
The y-intercept is 2, so our b will be 2
Slope is rise over run, or change in y over change in x , which is 6/3 = 2, so our m will be 2

The time it will take them to finish the journey is 2.6 hours
What is speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered.
It is measured in meter/sec(SI unit). it can also be measured in other units.
Speed is expressed as;
speed = distance /time
distance = 37.7 miles
speed = 14.5 miles per hour
time = distance /speed
= 37.7/14.5
= 2.6 hours.
Therefore it will take them 2.6 hours to finish the journey.

- If the line y = mx + c passes through the point of intersection of the lines x - 2y = -1 and y = 2 and is perpendicular to the line y = 4x + 8 , then find the values of m and c.
Help!! Irrelevant / Random answers will be reported*
Answer:
[tex]m = - \frac{1}{4} [/tex]
[tex]c = 2 \frac{3}{4} [/tex]
Step-by-step explanation:
Let's start by finding the point of intersection of the lines x -2y= -1 and y= 2.
x -2y= -1 -----(1)
y= 2 -----(2)
Substitute (2) into (1):
x -2(2)= -1
x -4= -1
x= 4 -1
x= 3
Thus, the point of intersection is (3, 2).
y= 4x +8
Slope= 4
The product of the slopes of perpendicular lines is -1.
4m= -1
m= -¼
y= -¼x +c
Since the line passes through (3, 2), we can substitute this coordinates into the equation to find the value of c.
When x= 3, y= 2,
[tex]2 = - \frac{1}{4} (3) + c[/tex]
[tex]c = 2 + \frac{3}{4} [/tex]
[tex]c = 2 \frac{3}{4} [/tex]

4 3/5 = 4.6 (decimal form)
3 3/5 = 3.6 (decimal form)
4.6 + 3.6 + 4.5 = 12.7

Answer:
x=-14
Step-by-step explanation:
Write the problem,
2x-5(x+4)=-2(x+3)
Distribute "-5" and "-2,"
2x-5x-20=-2x-6
Simplify,
-3x-20=-2x-6
Add "3x" to each side,
-20=x-6
Add "6" to each side,
-14=x
Y-4x=4 standard form
y - 4x = 4
y - 4x - 4 = 0
or
y = 4 + 4x
