The length of a rectangle is 7 centimeters greater than the width.
The perimeter is 54 centimeters. Find the length and width.
Answer:
length = 17cm, width = 10cm
Step-by-step explanation:
2L + 2w = 54
L = w + 7
Substitute:
2(w + 7) + 2w = 54
2w + 14 + 2w = 54
4w = 40
w = 10
L = 10 + 7 = 17

Step-by-step explanation:
PLEASE HELPP Find the value of x. Assume that segments that appear to be tangent are tangent. Round your answer to the nearest tenth.
The value of x assuming e that segments that appear to be tangent are tangent is 8
Circle geometryThe triangle inside the circle is right angles since the side length "x" is tangential to the circle.
To determine the value of "x", we will use the Pythagorean theorem as shown:
17^2 = x^2 + 15^2
289 = x^2 - 225
x^2 = 289 - 225
x^2 = 64
x = 8
Hence the value of x assuming e that segments that appear to be tangent are tangent is 8

The value of the cosine of an angle in Quadrant Il is given. cos theta= -2/5 What is sin theta? O- ✓29 5 V10 5 5 VI 21 5
Answer:
[tex]\frac{\sqrt{21} }{5}[/tex]
Step-by-step explanation:
Given
cosθ = - [tex]\frac{2}{5}[/tex]
Using the identity
sin²θ + cos²θ = 1 , then
sinθ = ± [tex]\sqrt{1-cos^20}[/tex]
= ± [tex]\sqrt{1-(-\frac{2}{5})^2 }[/tex]
= ± [tex]\sqrt{1-\frac{4}{25} }[/tex]
= ± [tex]\sqrt{\frac{21}{25} }[/tex]
= ± [tex]\frac{\sqrt{21} }{5}[/tex]
Since θ is in second quadrant the sinθ > 0 , thus
sinθ = [tex]\frac{\sqrt{21} }{5}[/tex]

Jerry wants to buy 4 Michelin tires. Each tire costs $213.99. Calculate his total price if the tax rate is 7.25%.
Answer:
$918.02
Step-by-step explanation:
As each tire costs $213.99, you will be multiplying that by 4:
$213.99*4 = $855.96
Now you will have to add the tax to the price. You will do the following:
$855.96*.0725 = 62.0571
You will round that to $62.06
$855.96+$62.06
The total would be $918.02
Write an equation in slope-intercept form of the line shown.
Answer:
y = 5/3x + 20/3
Step-by-step explanation:
Points on the graph: ( -4, 0) and (1, -5)
Slope:
m=(y2-y1)/(x2-x1)
m=(-5-0)/(1-4)
m=(-5)/(-3)
m=5/3
Slope-intercept:
y - y1 = m(x - x1)

These are the options for all three: 5/13, 12/5, 12/13, 5/12, 13/5, 13/12.
Answer:
sin x = 36/39 = 12/13cos x =15/39 = 5/13tan x = 36/15 = 12/5In this triangle,
Base ( B ) = 15 Hypothenuse ( H ) = 39 Perpendicular ( P ) = 36Find :-sin x = ?
cos x = ?
tan x = ?
Solution :-sin x = Perpendicular / Hypothenuse
= 36 / 39 = 12 /13
cos x = Base / Hypothenuse
= 15 / 39 = 5/13
tan x = Perpendicular / Base
= 36 /15 = 12 / 5

i need help to find m<k
Answer:
angle k = 72
Step-by-step explanation:
Hey There!
When triangles are similar all of the angles that correspond with each other are congruent ( have the same value)
ex. angle g and angle m are corresponding so they both equal 70
So to find angle K we have to find the value of angle F (because they are corresponding)
So we are given two angles
remember that all angles in a triangle will add up to equal 180
so we subtract the given angles from 180 to find the missing angle
180-38-70=72
so angle F = 72
like stated earlier angle F and angle K are corresponding so if angle F equals 72 then Angle K = 72

A clothing manufacturer uses the model a=f+4−−−−√−36−f−−−−−√ to estimate the amount of fabric to order from a mill. In the formula, a is the number of apparel items (in hundreds) and f is the number of units of fabric needed. If 4 apparel items will be manufactured, how many units of fabric should be ordered?
Questions:
A clothing manufacturer uses the model a = √(f + 4) - √(36 - f) to estimate the amount of fabric to order from a mill. In the formula, a is the number of apparel items (in hundreds) and f is the number of units of fabric needed. If 400 apparel items will be manufactured , how many units of fabric should be ordered?
Answer:
32 units of fabrics
Step-by-step explanation:
Given
[tex]a = \sqrt{f + 4} - \sqrt{36 - f}[/tex]
Required
Find f when a = 4
Substitute 4 for a
[tex]4 = \sqrt{f + 4} - \sqrt{36 - f}[/tex]
Rewrite as:
[tex]\sqrt{36 - f} + 4 = \sqrt{f + 4}[/tex]
Square both sides
[tex](\sqrt{36 - f} + 4)^2 = (\sqrt{f + 4})^2[/tex]
[tex](\sqrt{36 - f} + 4)^2 = f + 4[/tex]
[tex]36 - f + 8\sqrt{36 - f} + 16 = f + 4[/tex]
Collect Like Terms
[tex]8\sqrt{36 - f}= f +f+ 4 - 36 -16[/tex]
[tex]8\sqrt{36 - f}= 2f -48[/tex]
Divide through by 2
[tex]4\sqrt{36 - f}= f -24[/tex]
Square both sides
[tex]16(36-f) = (f - 24)^2[/tex]
[tex]16(36-f) = f^2 - 48f + 576[/tex]
[tex]576-16f = f^2 - 48f + 576[/tex]
[tex]-16f = f^2 - 48f[/tex]
Collect like terms
[tex]f^2 - 48f + 16f = 0[/tex]
[tex]f^2 -32f = 0[/tex]
Factorize
[tex]f(f - 32) = 0[/tex]
[tex]f = 0[/tex] or [tex]f = 32[/tex]
f can not be 0 because some units must be ordered.
So, f = 32
