Answer:
68 is the perimeter.
Step-by-step explanation:
You can find the perimeter by adding up all of the sides. 13 + 11 + 3 + 7 = 34. To find the other sides of the shape you do 11 + 7 and 13 + 3. 11 + 7 = 18. 13 + 3 = 16. 18 + 16 = 34. 34 + 34 = 68.

Answer:
[tex]\huge\boxed{\sf 350\ g\ salami = 5.565}[/tex]
Step-by-step explanation:
From the question:
100 g salami = 1.59
Divide 100 to both sides
1 g salami = 1.59/100
1 g salami = 0.0159
Multiply both sides by 350
350 g salami = 0.0159 × 350
350 g salami = 5.565

Which is the equation in slope-intercept form for the line that passes through (−1, 5) and is parallel to 3x + 2y = 4? y=−32x+72 y=23x+72 y=−23x+72 y=32x−72
Which is the equation in slope-intercept form for the line that passes through (−2, 15) and is perpendicular to 2x + 3y = 4?
y=32x+18
y=32x−12
y=23x+18
y=−32x+18
Which best describes the relationship between the lines?
2x – y = −1
4x – 2y = 6
parallel
same line
neither
perpendicular
1. The equation in slope-intercept form is: y = -3/2x + 7/2
2. y = -3/2x - 18
3. Both lines have the same slope, they are therefore parallel.
What is the Equation in Slope-intercept Form for Parallel Lines?Two lines that are parallel will have the same slope (m), and is represented by the equation in slope-intercept form as, y = mx + b.
1. Rewrite 3x + 2y = 4 in slope-intercept form:
2y = -3x + 4
y = -3x/2 + 4/2
y = -3/2x + 2
The slope is -3/2. Therefore, the slope (m) of the line that passes through (-1, 5) would be -3/2.
Substitute m = -3/2, and (a, b) = (-1, 5) into y - b = m(x - a):
y - 5 = -3/2(x - (-1))
y - 5 = -3/2(x + 1)
Rewrite in slope-intercept form:
2(y - 5) = -3(x + 1)
2y - 10 = -3x - 3
2y = -3x - 3 + 10
2y = -3x + 7
y = -3x/2 + 7/2
y = -3/2x + 7/2
2. The slopes of perpendicular lines are negative reciprocal to each other.
Rewrite 2x + 3y = 4
3y = -2x + 4
y = -2/3x + 4/3
The slope of the ine that passes (-2, 15) would be -3/2.
Substitute (a, b) = (-2, 15), and m = -3/2 into y - b = m(x - a):
y - 15 = -3/2(x - (-2))
y - 15 = -3/2x - 3
y = -3/2x - 3 - 15
y = -3/2x - 18
Therefore, the equation in slope-intercept form of the line that passes through (-2, 15) is: y = -3/2x - 18.
3. Given the equations, 2x – y = −1 and 4x – 2y = 6:
Rewrite in slope-intercept form and find their slope
2x - y = -1
-y = -2x - 1
y = 2x + 1 (slope if 2)
4x - 2y = 6
-2y = -4x + 6
y = -4x/-2 + 6/-2
y = 2x - 3 (slope is 2)
Both lines are therefore, parallel.

[tex]\dfrac{5(3+\sqrt{5})\sqrt{3-\sqrt{5}}}{4}[/tex]
[tex]\textsf{or}\quad \dfrac{5\sqrt{3+\sqrt{5}}}{2}[/tex]
Step-by-step explanation:
[tex]\textsf{Given expression}:\dfrac{5}{\sqrt{3-\sqrt{5}}}[/tex]
Method 1
[tex]\textsf{Multiply by the conjugate}\quad \dfrac{\sqrt{3-\sqrt{5}}}{\sqrt{3-\sqrt{5}}}:[/tex]
[tex]\implies \dfrac{5}{\sqrt{3-\sqrt{5}}} \times \dfrac{\sqrt{3-\sqrt{5}}}{\sqrt{3-\sqrt{5}}}=\dfrac{5\sqrt{3-\sqrt{5}}}{(\sqrt{3-\sqrt{5}})(\sqrt{3-\sqrt{5}})}[/tex]
Simplify the denominator using the radical rule [tex]\sqrt{a} \sqrt{a} =a[/tex]:
[tex]\implies (\sqrt{3-\sqrt{5}})(\sqrt{3-\sqrt{5}})=3-\sqrt{5}[/tex]
Therefore:
[tex]\implies \dfrac{5\sqrt{3-\sqrt{5}}}{(\sqrt{3-\sqrt{5}})(\sqrt{3-\sqrt{5}})}= \dfrac{5\sqrt{3-\sqrt{5}}}{3-\sqrt{5}}[/tex]
[tex]\textsf{Multiply by the conjugate}\quad \dfrac{3+\sqrt{5}}{3+\sqrt{5}}:[/tex]
[tex]\implies \dfrac{5\sqrt{3-\sqrt{5}}}{3-\sqrt{5}} \times \dfrac{3+\sqrt{5}}{3+\sqrt{5}}=\dfrac{5\sqrt{3-\sqrt{5}}(3+\sqrt{5})}{(3-\sqrt{5})(3+\sqrt{5})}[/tex]
Simplify the denominator:
[tex]\implies (3-\sqrt{5})(3+\sqrt{5})=9+3\sqrt{5}-3\sqrt{5}-5=4[/tex]
Therefore:
[tex]\implies \dfrac{5(3+\sqrt{5})\sqrt{3-\sqrt{5}}}{4}[/tex]
Method 2
[tex]\textsf{Multiply by the conjugate}\quad \dfrac{\sqrt{3+\sqrt{5}}}{\sqrt{3+\sqrt{5}}}:[/tex]
[tex]\implies \dfrac{5}{\sqrt{3-\sqrt{5}}} \times \dfrac{\sqrt{3+\sqrt{5}}}{\sqrt{3+\sqrt{5}}}=\dfrac{5\sqrt{3+\sqrt{5}}}{(\sqrt{3-\sqrt{5}})(\sqrt{3+\sqrt{5}})}[/tex]
Simplify the denominator using the radical rule [tex]\sqrt{a} \sqrt{b} =\sqrt{ab}[/tex]:

we can say rationalize by multiplying √(a-b) in numerator and denominator both

Mariam sells tires for $90 each and a service plan for $50. One customer
pays $410 for some tires and the service plan. Which equation represents
how many tires, t, the customer purchased?
A 410 = 50 + 90t
B 410 = 90 + 50t
© 410 = 50t + 90
D 410 = 90(4t) + 50
Answer:
the answer is A
Step-by-step explanation:
410 is the total amount paid
so 50 dollars was a base fee for the service charge
and 90 was per tire. Because we dont know how many tires she bought 90 x number of tires(t) = 90t
so 410 dollars = 50 dollars(service fee) + 90 dollars ( multilied by number of tires "t")
A man invests $8 000 at 12% simple interest for 3 years. If he invests the same amount of money for the same time period at 12% compound interest, what is the difference between the two investments?
Answer:
$359.42
Step-by-step explanation:
The difference in the investment values can be computed by making use of the formulas for the account balance in each case.
compound interest: A = P(1 +r)^t . . . . interest at rate r compounded annually
simple interst: A = P(1 +rt) . . . . simple interest at rate r
__
The account earning simple interest will have a balance of ...
A = $8000(1 +0.12×3) = $10,880
The account earning compound interest will have a balance of ...
A = $8000(1 +0.12)^3 ≈ $11,239.42
The difference between the two investments is ...
$11,239.42 -10,880 = $359.42
