Answer:
an = -5n +22
Step-by-step explanation:
We observe that the sequence has 17 as its first term and a common difference of 12-17 = -5. Then the general term is ...
an = a1 +d(n -1)
an = 17 -5(n -1)
This can be simplified to the desired form.
an = 17 -5n +5
an = -5n +22
The base of a triangle prism shown is an isosceles triangle having a height of H cm, and an area of 36cm squared
The perimeter of the front rectanglular face of the prism is 54cm
state the value of h on the diagram
Answers
Answer:
the value of h on the diagram is 9cm
Step-by-step explanation:
area = 1/2 * base * height
a = 1/2*b*h
36=1/2*8*h
36=4h
since the 1/2 will multiply the 8
36=4h
multiply both sides by 4
h=9cm.

Answers
Answer:
We can make the paint amount equal by making sure the parameters have the same unit
Step-by-step explanation:
Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
To solve the above question, we have the conversion rate:
We can make the paint amount equal by making sure the parameters have the same unit
Hence:
1 gallon (gal) = 3.785411784 kilogram (kg).
Billy had 5 gallons of paint.
1 gallon (gal) = 3.785411784 kilogram (kg).
5 gallons of paint = x
Cross Multiply
x = 5 × 3.785411784 kg
18.92705892 kilograms of paint
Approximately 18.93 Kilograms of paint
Therefore, Billy had 18.93 kg of paint and Bob had 4 kg of paint
A major storm has winds speeds that are at least 110 miles per hour.Write and solve an inequality that describes how much greater these wind speeds are than the slowest hurricane
Answers
Answer:
x ≥ 36 miles per hour
Step-by-step explanation:
The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.
Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:
x ≥ 110 miles per hour - 74 miles per hour
x ≥ 36 miles per hour
This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.

LLoyd used 1/4 of chocolate to make 2/3 gallons of chocolate pudding. If Lloyd's recipe is for 1 gallon of pudding, how many pounds of chocolate will he need to make 1/3 the recipe?
Answers
Answer:
1/8
Step-by-step explanation:
Llyod used 1/4 chocolates to make 2/3 gallons of chocolate pudding
= 1/4 ÷ 2/3
= 1/4 × 3/2

Answer:
(-2, -4) or x = -2 y = -4
Step-by-step explanation:
Solve with subsitution
y-3x=2
y=-2x-8
1. Substitute -2x - 8 in for the y in y - 3x = 2 (-2x - 8) - 3x = 2
2. Solve for x. Combine like terms. -5x - 8 = 2
3. Solve the one step equation. +8 +8
-5x = 10
-5 -5
x = -2
4. Substitute the -2 in for x in either equation. y = -2x - 8
y = -2(-2) - 8
y = 4 - 8
y = -4

[tex]2x^2-20x=x^{2} -19[/tex]
Answers
Answer:
x = 1, x = 19
Step-by-step explanation:
Given
2x² - 20x = x² - 19 ( subtract x² - 19 from both sides )
x² - 20x + 19 = 0 ← in standard form
(x - 1)(x - 19) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 19 = 0 ⇒ x = 19

Chris works at a jewelry store, and he earns 4% commission on all sales that he makes. If Chris's jewelry sales total $1,370, how much will he earn in commission?
Answers
Answer:
[tex]\boxed {\boxed {\sf \$54.80}}[/tex]
Step-by-step explanation:
Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.
[tex]commission= commission \ rate * sales[/tex]
His rate is 4% and his sales are $1,370
[tex]commission= 4\% * \$1370[/tex]
Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.
4/100= 0.04 4.0 --> 0.4 --> 0.04[tex]commission= 0.04* $1370[/tex]
[tex]commission = \$ 54.8[/tex]
