The linear inequality represented by the graph is y ≤ 1/2x + 2

From the graph, we have the following highlights:

Next, we calculate the slope (m) using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

Using the points on the graph, we have:

[tex]m = \frac{4 -2}{4 -0}[/tex]

Evaluate

m = 1/2

The first highlight implies that the y-intercept is 2.

So, the linear inequality is:

y ≤ mx + c

This gives

y ≤ 1/2x + 2

Hence, the linear inequality represented by the graph is y ≤ 1/2x + 2

Answer:

The answer is 1
- One is the most frequent digit used for writing numbers between 1-1000
- its because 1 has 1 in it and 1000 also has one in it so it can't be other numbers from 1-9
- It can't be zero as zero is not repeated as much as 1
- so the answer is 1

Answer:

surface area of cuboid = 190 in²

surface area of triangular prism = 1240 yd²

surface area of cone = 791.28 ft²

Step-by-step explanation:

cuboid formula = 2( l x b + l x h + h x b )

solution:

S.A = 2(l x b + l x h + h x b)

S.A = 2(5 x 3 + 5 x 10 + 10 x 3)

S.A = 2(15 + 50 + 30)

S.A = 2( 95 )

S.A = 190 in²

triangular prism formula = 2(1/2 (b x h)) + 2(l x b) + l x b(this formula can only be used for this type of triangular prism)

solution:

S.A = 2(1/2 (b x h)) + 2(l x b) + l x b

S.A = 2(1/2 (15 x 16)) + 2(17 x 20) + 20 x 16

S.A = 240 + 680 + 320

S.A = 1240 yd²

cone formula = [tex]\pi[/tex]r(l + r) or [tex]\pi[/tex]rl + [tex]\pi[/tex]r²

solution:

S.A = [tex]\pi[/tex]r[l+r]

S.A = 3.14(9)[19 + 9]

S.A = 28.26 x 28

S.A = 791.28 ft²

Answer:

Andrew is 30 years old. Hunter is 65 years old.

Step-by-step explanation:

we can set up 2 equations:

h = 35 + a

h+5 = 2(a+5)

Solve for h in the second equation.

h + 5 = 2a + 10; h = 2a + 5

now set the 2 equations = to each other

2a + 5 = 35 + a

solve for a by combining like terms

a + 5 = 35

a = 30

so Andrew is 30 and Hunter is 35 + 30 = 65.

Sp in 5 years Andrew is 35 and Hunter is 70 (twice A's age)

Answer:

So that means that

h=35+a+5

because he already is 35

we add Andrew's Age

And we add 5 for 5 extra years

Therefore,

35+5=40.

40+a = 2a+10

Substract the a

40 = a+10

Subtract 10

30 = a

If Andrew's age is 30, going back to our first equation,

Hunter's Age = 65

Andrew's Age = 30

Answer:

30%

Step-by-step explanation:

To solve this, you must first find the areas of the circle and the pentagon within it.

Find the area of the circle:

The area of a circle is πr² and the circle in the diagram is shown to have a radius of 4cm, so to find its area, plug 4 into the equation

A = πr²  ⇒  A = π(4)²  ⇒  A = 16π

Find the area of the pentagon:

To find the area of a pentagon, you should first know that the shape is simply five triangles combined into one shape. (See Image)

With the formula for the area of a triangle in mind, it should be known that the pentagon's side acts as a base and the pentagon's apothem (dotted line) acts as a height for each triangle. According to the diagram, the base length is 4.7 and the height is 3.2. To find the area of any of the triangles, plug these values into the formula for the area of a triangle:

A = [tex]\frac{1}{2}[/tex]bh  ⇒  A = [tex]\frac{1}{2}[/tex](4.7)(3.2)    ⇒  A = 7.52 cm²

Since a pentagon is made of five of these, simply multiply the area you just found by 5 to find its area:

A = 7.52 * 5 = 37.6 cm²

Find the area of the white parts:

To find the area of the white parts, subtract the area of the pentagon from the area of the circle:

16π - 37.6 = 12.67 cm²

Now all that's left is to find the probability, all you have to do is

Divide the area of the white by the area of the circle:

12.67 / 16π = .25, which is .3 rounded to the nearest tenth.

That means that the probability that a randomly selected point within the circle falls in the white area is 30%

Hope this worked!

[tex]f(1) = 3^x-3 = 3^1-3=3-3=0[/tex]

To solve f(1), we simply plug 1 into all the x's position

             --> the exponent of 3 in this case

First of all find the total area and then subtract the area of circle from the area of rectangle, It will be easier that way...

Answer:

385 miles

Step-by-step explanation:

Let's start by finding the unit rate (how far she can drive in 1 hour):

[tex]\frac{165mi}{3hr}[/tex]

Divide both the numerator and the denominator by 3 hours (Please note that this is essentially dividing the fraction by 1, so we are only simplifying the fraction, not changing it):

[tex]55mi/hr[/tex]

Now, using a unit converter, we can find out far she can drive in 7 hours:

[tex]7hr(\frac{55mi}{1hr})=7*55mi=385mi[/tex]

She can drive 385 miles in 7 hours

Answer:

You want to set up an equation that will match the word problem. Let's call the amount of the first brand, F, and the amount of the second brand, S.

We want the total mixture to be 310mL so: F + S = 310

Also, you want the total mixture to contain 8% vinegar so: .06F + .11S = .08(310)

Now, we can solve the system of equations using substitution.

F + S = 310

.06F + .11S = .08(310)

F = 310 - S      [solve 1st equation for F]

.06(310 - S) + .11S = .08(310)     [substitute into 2nd equation]

18.6 -.06S +.11S = 24.8

.05S = 6.2

S = 124

F + 124 = 310     [substitute answer for S back into original equation]

F = 186

Answer: To make a 310mL mixture that contains 8% vinegar, use 186mL of the first brand and 124mL of the second brand.

Step-by-step explanation:

The answer is 33/5.

To multiply fractions, you multiply the numerators to get the numerator of the product and multiply the denominators to get the denominator of the product and then simplify the product. Also, you can make a whole number, which is 28 in this case, into a fraction by putting it over 1. So, that would be 28/1.

First, I multiplied the numerators:

4(11)(28)(9) = 11088

Next, multiply the denominators (and im assuming that last one is a 48, its a bit covered up by the mouse):

5(7)(1)(48) = 1680

So that's 11088/1680

Lastly, you simplify this to get 33/5 (I just used desmos scientific calculator for all of this)

Hope that helps :]

The perimeter and the area of the shape are 63 square yards and 46 yards, respectively.

The area of a triangle is equal to one half the product of its base and height. In the image, the base of the triangle is 18 yards and the height is 7 yards. Therefore, the area of the triangle is:

area = (1/2) * base * height

= (1/2) * 18 * 7

= 63 square yards

The perimeter of the shape is the sum of the lengths of all of its sides. In the image, the lengths of the sides are 6 yards, 18 yards, 7 yards, and 15 yards.

Therefore, the perimeter of the shape is:

perimeter = 6 + 18 + 7 + 15

= 46 yards

[8] The hypotenuses must be congruent, DE and IJ

     HL is hypotenuse-leg, or where the hypotenuse and one leg are congruent.

     Since we see a leg is congruent, to prove they are congruent with HL we will need to know that the hypotenuses are congruent.

[9] Another leg, AC and YX

     LL is leg-leg. Since we have one leg, we will need the other leg to prove the triangles are congruent by LL.

[10] A leg, DE and E? or FE and E?

     LA means leg-angle. The angles by point E are vertical angles, so they will be congruent. To finish prooving the congruence using LA we will also need a leg.
