HELPPP MEEEEEEEEEE!!!

Answer:

x=4

Step-by-step explanation:

1. isolate the variable by subtracting 7 on both sides: 4x=23-7

2. simplify: 4x=16

3. divide both sides by 4: x=16/4

4. simplify: x=4

Answer:

x=4

Step-by-step explanation:

4x+7=23

Collect like terms

4x=23-7

4x=16

Divide both sides by the co-efficient of x

4x/4=16/4

x=4

Answer:

[tex]\boxed {\boxed {\sf 2 \ significant \ figures}}[/tex]

Step-by-step explanation:

According to the "rules" of significant figures, all the zeroes to the right of the final non-zero number are not significant, unless there is a decimal point.

We are given the measurement:

84,000 kg

If there was a decimal point (84,000.0 kg), then there would be 5 significant figures.

Since there isn't a decimal point, all 3 zeroes to the right of the number 4 aren't significant. The 8 and 4 are significant, so there are 2 significant figures.

Answer:

12 hours

Step-by-step explanation:

So, 7 times 3 is 21. This means he have to multiply 4 by 3 to get 12.

The part-to-part ratio to represent this ratio relationship is 1:0.75.

The ratio language to describe this ratio relationship shows that for every four squares, there are three triangles.

Based on the information given, it should be noted that the part-to-part ratio to represent this ratio relationship is 1:0.75.

This illustrates that for every one square, there is 0.75 triangle.

This was based on the fact that there are 3 triangles and 4 squares. This will be:

= 3/4 = 0.75

Therefore, the ratio language to describe this ratio relationship shows that for every four squares, there are three triangles.

Answer:

4/3, or 1 1/3

Step-by-step explanation:

For a whole number, 1 is always the denominator. It would look like 4/1 x 3/8. Then you would multiply both the numerators and denominators. That would get you 12/8. Simplify it, to get 4/3. If you want to simplify it even more, you would get 1 1/3.

Answer:

Step-by-step explanation:

this is a piecewise function

in this context, to find the cost of any package weight x you figure out which piece of the function it fits in.

examples:

x = .5

c(x) = 0.37 (because x is less than 1)

x = 1

c(x) = 0.60 (because x is equal to 1 but still less than 2)

x = 2.9

c(x) = 0.83 (because x is more than 2 but less than 3)

Answer:

The profit in 1960 (i.e. year 1) was 3280 dollars

Step-by-step explanation:

Given

[tex]P(t) = 2t^3 - 152t^2 + 3400t + 30[/tex]

Where

t = years since 1960 (the first year)

Required

Determine the profit in 1960

Since the first year is 1960, then [tex]t =1[/tex]

To get the profit, we simply substitute 1 for t in [tex]P(t) = 2t^3 - 152t^2 + 3400t + 30[/tex]

[tex]P(t) = 2t^3 - 152t^2 + 3400t + 30[/tex] becomes

[tex]P(1) = 2(1)^3 - 152(1)^2 + 3400(1) + 30[/tex]

[tex]P(1) = 2*1 - 152*1 + 3400*1 + 30[/tex]

[tex]P(1) = 2- 152 + 3400 + 30[/tex]

[tex]P(1) = 3280[/tex]

Hence, the profit in 1960 (i.e. year 1) was 3280 dollars

Answer:

[tex](fg)(x) = 75[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 3x^2 + 3[/tex]

[tex]g(x) = 3x - 1[/tex]

Required

Evaluate (fg)(x) for x = 2

In algebra functions

[tex](fg)(x) = f(x) * g(x)[/tex]

Substitute values for f(x) and g(x)

[tex](fg)(x) = (3x^2 + 3) * (3x - 1)[/tex]

Substitute 2 for x

[tex](fg)(x) = (3*2^2 + 3) * (3*2 - 1)[/tex]

[tex](fg)(x) = (3*4 + 3) * (6 - 1)[/tex]

[tex](fg)(x) = (12 + 3) * (5)[/tex]

[tex](fg)(x) = (15) * (5)[/tex]

[tex](fg)(x) = 15 * 5[/tex]

[tex](fg)(x) = 75[/tex]

Answer:

Variance = 3.9

Standard deviation = 1.975

p(x > 72) = 0.38482

Step-by-step explanation:

Given that :

Mean number (μ) of strokes per hole is approximately 3.9

For a poisson distribution :

σ² = μ

Hence,

Variance (σ²) = μ = 3.9

The standard deviation σ = √(σ²)

σ = √3.9 = 1.9748417

Poisson distribution relation :

p( x = x) = (λ^x * e^-λ) / x!

For an 18-hole round :

λ = 18 * 3.9 = 70.2

Using the poisson distribution calculator ; where λ = 70.2 ; x = 72

p(x > 72) = 0.38482

Answer:

There are 60 green paper clips.

Step-by-step explanation:

if 2/3 of the box = 120 clips, then you can determine that 1/3 is 60, since 1/3 is half of 2/3. If 1/3 is 60, Since you already know that 2/3 is 120 clips, you add 60 to get 180 total clips, and 60 of them are green.

Answer:

60 Green Paper Clips

Step-by-step explanation:

120/2 = 60 (which would be 1/3)

Answer:

Step-by-step explanation:

Let shakes be s and hamburgers be h. Then the total cost equation would be

2s + 3h = 17

The next equation in our system will be

3s + 4h = 24

You can solve this by either substitution or elimination. I'm going with substitution because it's easier in this platform to do so. I'm going to solve the second equation for h.

4h = 24 - 3s and

h = 6 - .75s

Now we will sub that into the first equation to get

2s + 3(6 - .75s) = 17 and

2s + 18 - 2.25s = 17 and

-.25s = -1 and

s = 4

That means that shakes cost $4 each. Now plug in 4 for s and solve for h:

h = 6 - .75(4) and

h = 6 - 3 so

h = 3 so hamburgers cost $3 each.

Answer:

Step-by-step explanation:

Answer:

204.2 units

Step-by-step explanation:

Area of semicircle: 1/2(πr^2)

r = 5

1/2(π(5)^2)

94.2477796

Area of Rectangle: w * l

l = 11

w = 5(2)

11 * 5(2) = 11 * 10 = 110

Total:

110 + 94.2 = 204.2 units

Answer:

Step-by-step explanation:

total area = rectangle + semicircle

                = (11 x 10) + (1/2 x π 5²)

                = 110 + 39.27

                = 149.3

Answer:

[tex] x = 17 [/tex]

Step-by-step explanation:

Since line m is parallel to line n, therefore:

[tex] (6x + 5) + (5x - 12) = 180 [/tex] (consecutive interior angles are supplementary)

Solve for x

[tex] 6x + 5 + 5x - 12 = 180 [/tex]

Add like terms

[tex] 11x - 7 = 180 [/tex]

Add 7 to both sides

[tex] 11x - 7 + 7 = 180 + 7 [/tex]

[tex] 11x = 187 [/tex]

Divide both sides by 11

[tex] \frac{11x}{11} = \frac{187}{11} [/tex]

[tex] x = 17 [/tex]

Answer:

21 cups of coffee

Step-by-step explanation:

So the coffee:tea is 3:2. We can put it as 3x+2x=35 as we know there are 35 drinks, do not know the exact number of coffee and tea, but know the ratio.

Now, x=7. So coffee is 3(7)=21 and tea is 2(7)=14.

Option (c) "[tex]r=\dfrac{q}{4c}-h[/tex]"

Step-by-step explanation:

The given equation is :

q = c4(h + r)

We need to solve it for r.

Dividing both sides of the given equation by 4c.

[tex]\dfrac{q}{4c}=\dfrac{4c}{4c}(h+r)\\\\(h+r)=\dfrac{q}{4c}[/tex]

Now, subtract h both sides of the equation.

[tex]h+r-h=\dfrac{q}{4c}-h\\\\r=\dfrac{q}{4c}-h[/tex]

Hence, this is the required solution.
