You are making gluten-free baked goods for a bake sale. One type of gluten-free flour costs $7 for a 3-pound bag. You can spend at most $28. Let n be the number of 3-pound bags of gluten-free flour you can buy. Write an inequality that represents the situation.
Answer:
Step-by-step explanation:
The answer to your question is 7n ≤ 28
Data
Cost of 1 bag = $7
The maximum amount of money spent = $28
n = number of 3-pound bags
Process
- We know that the amount spent must be at most = $28, so we use the symbol ≤.
- The money spend is the price of one bag times the number of bags bought.
- Then the inequality is
7n ≤ 28

Step-by-step explanation:
Volume = 0.5 * Base * Height * Length
You have to multiply by 0.5 because it is a Triangular prism
base(b) = 4.1
Height (h) = 7.2
Length (l) = 3.5
Plug in the numbers to the equation below and you get 51.66

A real estate agent believes that the value of houses in the neighborhood she works in has increased from last year. To test this claim, she selects random houses in this neighborhood and compares their estimated market value in the current year to their estimated market value in the previous year. Suppose that data were collected for a random sample of 8 houses, where each difference is calculated by subtracting the market value of the previous year from the market value of the current year. Assume that the values are normally distributed. The agent uses the alternative hypothesis Ha:μd>0. Using a test statistic of t≈7.496, which has 7 degrees of freedom, determine the range that contains the p-value.
Answer:
The range is [tex]-0.00007 < p-value < 0.00007[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 8
The null hypothesis is [tex]H_o : \mu_d = 0[/tex]
The alternative hypothesis is [tex]H_a : \mu_d > 0[/tex]
The test statistics is [tex]z \approx 7.496[/tex]
The degree of freedom is [tex]df = 7[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = P(Z > 7.496 )[/tex]
Generally from the t distribution table
(Reference -
danielsoper(dot)com(slash)statcalc(slash)calculator)
the value of [tex]P(Z > 7.496 )[/tex] at a degree of freedom 7 is
[tex]P(Z > 7.496 ) = t_{7.496 , 7 } =0.00007[/tex]
So the range that contains the p -value is
[tex]-0.00007 < p-value < 0.00007[/tex]

Solve for x. PLEASE HELP ME
can someone please help me
Answer: X=6 AB= 52
Step-by-step explanation:
7x + 10 = 9x -2 (because the sides are equal) & solve.
subtract the 7x on both sides.
10 = 2x -2
add 2 on both sides
12 = 2x
divide by 2
x = 6
Answer:
x = 4
AB = 52
Step-by-step explanation:
The dashes on the line segments AB and BD mean that they are equal in length.
⇒ 7x + 10 = 9x - 2
Add 2 to both sides:
⇒ 7x + 10 + 2 = 9x - 2 + 2
⇒ 7x + 12 = 9x
Subtract 7x from both sides:
⇒ 7x + 12 - 7x = 9x - 7x
⇒ 12 = 2x
Divide both sides by 2:
⇒ 12 ÷ 2 = 2x ÷ 2
⇒ 6 = x
⇒ x = 6
Substitute x=6 into the expression for AB to find the length of AB:
⇒ AB = 7(6) + 10
⇒ AB = 42 + 10
⇒ AB = 52

11) V = tr2h solve for r2
Answer:
[tex]r^{2}=\frac{V}{\pi h}[/tex]
Step-by-step explanation:
To solve an equation for one of its variables do that:
Underline the variableSeparate it one side and the other terms on the other sideMake its coefficient equal to 1Let us use these steps to solve our question
∵ V = πr²h
→ Underline r²
∴ V = πr²h
→ Take π and h to the other side by dividing both sides by πh
∵ [tex]\frac{V}{\pi h}=\frac{\pi r^{2}h}{\pi h}[/tex]
∴ [tex]\frac{V}{\pi h}=r^{2}[/tex]
→ The coefficient of r² is 1, so switch the two sides
∴ [tex]r^{2}=\frac{V}{\pi h}[/tex]

The height of the object after 1 sec is 284 feet
Equation of height of an objectGiven the equation of height of an object expressed as:
h(t) = -16t^2 + 300t
We are to find the height of the object after 1 sec. To do that, we will substitute t = 1 into the following expression
h(t) = -16t^2 + 300t
h(1) = -16(1)^2 + 300(1)
h(1) = -16 + 300
h(1) = 284ft
Hence the height of the object after 1 sec is 284 feet

Suppose y varies directly as x, and y=8 when x=2 find when x=21
x2 − 15x = −50 A) x = 3, x = 5 B) x = 5, x = 10 C) x = 3, x = −5 D) x = −5, x = −10
Answer:
x = 10 or x = 5 thus: B is the answer
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 15 x = -50
Add 225/4 to both sides:
x^2 - 15 x + 225/4 = 25/4
Write the left-hand side as a square:
(x - 15/2)^2 = 25/4
Take the square root of both sides:
x - 15/2 = 5/2 or x - 15/2 = -5/2
Add 15/2 to both sides:
x = 10 or x - 15/2 = -5/2
Add 15/2 to both sides:
Answer: x = 10 or x = 5

Find the slope of the line through each pair of points.
a)( -7 , 16 ) , ( 4 , - 4 ) b) ( -5 , -20 ) , ( -12 , - 10 )
Answer:
a) -20/11 b) -10/7
Step-by-step explanation:
a) m=(y2-y1)/(x2-x1)
m=(-4-16)/(4-(-7))
m=-20/(4+7)
m=-20/11
b) m=(y2-y1)/(x2-x1)
m=(-10-(-20))/(-12-(-5))
m=(-10+20)/(-12+5)
m=10/-7
m=-10/7
