After that he made $6.25 per hour for each hour he worked. Write the equation in
slope-intercept form that represents the equation.
Answer:
y=6.25x+10

Solving Linear Equations Unit Test 16 of 20Items Item 16 Gold has a density of 0.70 pounds per cubic inch and copper has a density of 8.96 grams per cubic centimeter. How much will 1 cubic foot of each metal weigh? 1 ft3 = 1728 in3, 1 ft3 = 28,316.8 cm3, and 1 lb=453.5 g. Use the equation rho=mV. (1 point) The gold will weigh 4063.4 pounds and the copper will weigh 12,096 pounds. The gold will weigh 559 pounds and the copper will weigh 1209.6 pounds. The gold will weigh 12,096 pounds and the copper will weigh 4063.4 pounds. The gold will weigh 1209.6 pounds and the copper will weigh 559 pounds.
Answer:
1 ft³ of gold will weigh 1209.6 pounds
1 ft³ of copper will weigh 559 pounds.
Step-by-step explanation:
We know the formula for:
Density = Mass/Volume
Hence, making mass the subject of the formula:
Mass = Density × Volume
From the question we are told:Volume of each metal = 1 ft³
1) Metal: Gold
Density of Gold = 0.70 pounds per cubic inch(lb/in³)
We convert the Volume of gold from ft³ to in³
The Volume of gold given in the question = 1 cubic foot = 1 ft³
1 cubic foot = 1728 cubic inches
Hence, the volume of Gold = 1728 in³
Mass of Gold = Density of Gold × Volume of Gold
Mass of Gold = 0.70Ib/in³ × 1728 in³
= 1209.6 lb(pounds)
2) Metal : Copper
Density of copper given in the question = 8.96 grams per cubic centimeter
Ib = pounds
We convert this density in g/cm³ to ib/in³
453.5g = 1 Ib
8.96g = a Ib
Cross Multiply
= 453.5g × a Ib =8.96g × 1 Ib
= a Ib = 8.96g × 1 Ib/453.5g
a Ib = 0.0197574421 Ib
Density of Copper = 0.0197574421 Ib/cm³
28,316.8 cm³ = 1 ft³
1 cm³ = b ft³
b ft³ = 1 cm³ × 1 ft³/28,316.8cm³
b ft³ = 0.0000353147 ft³
1 cm³ = 0.0000353147 ft³
We have to convert the density of Copper from Ib/cm³ to Ib/ft³
0.0197574421 Ib/cm³ = 0.0197574421 Ib/0.0000353147 ft³
559.46793026 Ib/ft³
Volume of copper = 1ft³
Mass = Density × Volume
Mass of copper = 559.46793026 Ib/ft³ × 1 ft³
= 559.46793026 Ib or pounds
≈ 559 pounds
Therefore , the weight of gold is 1209.6 pounds and the weight of copper will be 559 pounds.
Answer:
Gold
Density of Gold = 0.70 pounds per cubic inch
1 cubic foot = 1728 cubic inches
Hence, the volume of Gold = 1728 in³
Mass of Gold = Density of Gold × Volume of Gold
Mass of Gold = 0.70Ib/in³ × 1728 in³ = 1209.6 lb(pounds)
2) Metal : Copper
Density of copper given in the question = 8.96 grams per cubic centimeter
We convert this density in g/cm³ to ib/in³
453.5g × a Ib =8.96g × 1 Ib = 8.96g × 1 Ib/453.5g = 0.0197574421 Ib
Density of Copper = 0.0197574421 Ib/cm³
Volume of copper = 1ft³
Mass = Density × Volume
Mass of copper = 559.46793026 Ib/ft³ × 1 ft³ = 559.46793026 Ib or pounds
≈ 559 pounds
The weight of gold is 1209.6 pounds and the weight of copper will be 559 pounds.

Point (2, 4) is reflected across the x-axis. What are
the coordinates of its image?
Answer:
The coordinates of its image are (2, -4)
Step-by-step explanation:
Let us revise the rules of reflection across the axes
If the point (x, y) reflected across the x-axis, then its image is (x, -y), the rule of reflection is rx-axis (x, y) → (x, -y) If the point (x, y) reflected across the y-axis, then its image is (-x, y), the rule of reflection is ry-axis (x, y) → (-x, y)∵ The point (2, 4) is reflected across the x-axis
→ By using the first rule above rx-axis (x, y) → (x, -y)
∴ Change the sign of its y-coordinate
∴ Its image is (2, -4)
∴ The coordinates of its image are (2, -4)

O 3(3x+24y)
O 3xy(3x+247)
Plzz helpp
Answer:
3(x + 8y)
Step-by-step explanation:
3 is the highest term that can be factored out; there are no other numbers/variables in common.
Factor out 3 from 3x + 24y.
= 3(x+8y)
The factored form of the given expression is 3(x+8y).
What are factors?A factor is a number that divides into another number without a remainder. So, for example, 5 is a factor of 20 because 20/5 = 4. There is no remainder. You can also think of factors as the numbers that you multiply together in order to obtain a product.
Given is an expression 3x+24y, we need to find the factors of the given expression,
3x+24y
Since, 3 is the highest term that can be factored out; there are no other numbers/variables in common.
Factor out 3 from 3x + 24y.
= 3(x+8y)
Hence, the factored form of the given expression is 3(x+8y).

which is larger -17/24 or -11/12
Answer:
-17/24
Step-by-step explanation:
Because they are negative numbers, the smaller fraction (when disregarding the negative sign) is always a larger number. -11/12 could be changed to -22/24, and therefore since it is a larger number when disregarding the negative (22/24), it is a smaller number altogether.
-17/24 > -22/24

Lance has 3 time as many pencils as Nick, and they have 84 pencils together. How many pencils does each of them have?
Answer:
21 pencils for Nick and 63 pencils for Lance
Step-by-step explanation:
Lance is said to have 3 times the pencils Nick has.Let's keep the number of pencils Nick has as x.If Nick has x pencils that means Lance has 3x pencils. The total number of pencils present is 84.Now let's make an equation out of the information above:
3x + x = 84
Now solve for x.
3x + x = 84
4x = 84
x = 84/4
x = 21
So Nick has 21 pencils
Now for Lance:
3x
3 * (21) = 63
So Lance has 63 pencils
63 + 21 = 84 pencils

What are 2 numbers that add to 40 and subtract to 10
Answer:
25 and 15
Step-by-step explanation:
let the 2 numbers be x and y , x > y , then
x + y = 40 → (1)
x - y = 10 → (2)
add the 2 equations term by term to eliminate y
2x + 0 = 50
2x = 50 ( divide both sides by 2 )
x = 25
substitute x = 25 into (1)
25 + y = 40 ( subtract 25 from both sides )
y = 15
the 2 numbers are 25 and 15
3 times x plus 4 is greater than or equal to 4 times the sum of x and 1. (Hint: 4 times the sum means you should write a distributive property problem)
Given:
3 times x plus 4 is greater than or equal to 4 times the sum of x and 1.
To find:
The inequality for the given statement and solution of the inequality.
Solution:
4 times the sum means a distributive property problem.
Now,
3 times x : 3x
3 times x plus 4 : 3x+4
Greater than or equal to : ≥
4 times the sum of x and 1 : 4(x+1)
So, the inequality is
[tex]3x+4\geq 4(x+1)[/tex]
Using distributive property, we get
[tex]3x+4\geq 4x+4[/tex]
Isolate variable terms.
[tex]4-4\geq 4x+3x[/tex]
[tex]0\geq x[/tex]
It can be written as
[tex]x\leq 0[/tex]
Therefore, the required inequality is [tex]3x+4\geq 4(x+1)[/tex] and the solution is [tex]x\leq 0[/tex].
