Answer:

9. SSS

10. ASA

11. NONE

12. NONE

Step-by-step explanation:

9. The figure shows two triangles with two corresponding sides indicated to be congruent to each other. The third side is shared by both triangles. Therefore, by the SSS Congruence Theorem, both triangles are congruent to each other. Three sides of one triangle is congruent to the corresponding sides of the other.

10. The figure shows that two angles of one ∆ is congruent to two corresponding angles of the other ∆. Also, the triangles share a common side. This side is an included side between the two given angles. Therefore, by ASA Congruence Theorem, both triangles are congruent to each other.

11. This figure shows the two triangles have 3 corresponding equal angles. This is not enough to prove they are congruent.

12. The two triangles has two corresponding congruent sides given. However, we don't have enough information to determine if they are congruent to each other.

Answer:

100 days

Step-by-step explanation:

If you have 60 customers that pay everday $50, 60 multiplied by $50 is $3,000 a day. You take your debt, 300,000 and divide that with the 3,000. Thus gives the answer 100 days.

Answer:

100 days

Step-by-step explanation:

First, you must take the 60 customers and multiply it by the $50 daily. That equals 3,000 dollars, so the restaurant is earning that much each day. In order to make 300,000 dollars, it would take 100 days. This is because 300,000/3,000 is 100. I hope this helps!:))

Answer:

Step-by-step explanation:

Answer:

$56

Step-by-step explanation:

The jacket is on sales for 30% off the original price = (0.3)

The original price (P) = $80

However, the expression "p - 0.3p" is to be used to find the sales price

The sale price = p - 0.3p

The sale price = $80 - 0.3($80)

The sale price = $80 - $24

The sale price = $56

Answer:

In the ocean, warmer water expands just like any other matter, and following the principle of density, it rises to the top of the ocean. The cooler water, which is more dense than the warm water, sinks to the bottom and takes up the space left by the rising warm water. The result is a convection current.

Step-by-step explanation:

Answer: А. On average, the number of students going to an office hour varies from the mean by about 2.2 students

Step-by-step explanation:

The standard deviation is a measure of spread, which gives how values deviate from the average or mean value of a particular distribution. Hence, the standard deviation is usually defined about the average value of a distribution.

Therefore, for a certain random variable representing the number of student who visits office hours, the standard deviation will be defined about the average or mean value of the random variable Q.

Thus, stated as ; number of students going to an office hour varies from the mean by 2.2 on average.

Answer:

188 weeks of data must be sampled.

Step-by-step explanation:

From the information given, we can deduce that:

The Margin of error is within = 200

The confidence interval = 95%

The level of significance = 1 - C.I

= 1 - 0.95

= 0.05

The standard deviation = 1400

The number of weeks the data must be sampled can be determined by using the formula for sample size which is:

[tex]n =( \dfrac{Z_{\alpha/2} \times \sigma}{E} )^2[/tex]

[tex]n =( \dfrac{Z_{0.05/2} \times 1400}{200} )^2[/tex]

[tex]n =( \dfrac{1.96 \times 1400}{200} )^2[/tex]

[tex]n =( \dfrac{2744}{200} )^2[/tex]

[tex]n =( 13.72)^2[/tex]

n = 188.24

n ≅ 188

Thus, 188 weeks of data must be sampled.

Answer:

Domain and Range in set notation

Domain: {x|x=4,0,-2}

Range: {x|x=-1,4,9,-9}

Step-by-step explanation:

We are given a relation G

G={(4,-1),(0,4),(-2,9),(-2,-9)}

We need to find domain and range of the relation G

Domain: The domain is the set of all first elements of ordered pairs (x-coordinates)

Range: The range is the set of all second elements of ordered pairs (y-coordinates).

So for the given relation G={(4,-1),(0,4),(-2,9),(-2,-9)}

Domain is: (4,0,-2)

Range is: (-1,4,9,-9)

So, Now writing Domain and Range in set notation

Domain: {x|x=4,0,-2}

Range: {x|x=-1,4,9,-9}

Answer:

1936 m2

Lot = 60 x 36 = 2160m^2

House = 28 x 8 = 224m^2

Area not covered by the house = 2160^2 - 224^2

= 1936m^2

Answer:

The constant of proportionality is 5

Step-by-step explanation:

Given

[tex]y = \$30[/tex] --- Cost

[tex]x = 6[/tex] --- Number of shirts

Required

Determine the constant of proportionality

The relationship between y and x is:

[tex]y =kx[/tex]

Where:

k = constant of proportionality

Substitute [tex]30\ for\ y[/tex] and [tex]6\ for\ x[/tex]

[tex]30 = k * 6[/tex]

[tex]30 = 6k[/tex]

Divide both sides by 6

[tex]\frac{30}{6} = \frac{6k}{6}[/tex]

[tex]\frac{30}{6} = k[/tex]

[tex]5 = k[/tex]

[tex]k = 5[/tex]

The constant of proportionality is 5

Answer:

the answer is A because anything with an exponent of 0 is = to 1

Answer:

y=1/3x

When x of the line is -3, y of the line must be -1.When x of the line is 6, y of the line must be 2. y=1/3x+b. b is what we want, the 1/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the two points (-3,-1) and (6,2).(-3,-1). y=mx+b or -1=1/3 × -3+b, or solving for b: b=-1-(1/3)(-3). b=0.b came out to be zero, so there is no "+b" term.

Answer:

C

Step-by-step explanation:

Answer:

C choice.

Step-by-step explanation:

We can either solve the equation or substitute x = 4 to find the true equation.

Solve The Equations

1. 4x=20

Our solution would be x = 5 as we move 4 to divide 20.

2. x/2=8

Our solution would be x = 16 as we move 2 to multiply 8.

3. x+8=3x

Our solution would be x = 4 which is the answer. We basically move x to subtract 3x as we get 8 = 2x.

Then we move 2 to divide 8 as we get x = 4.

[tex]x + 8 = 3x \\ 8 = 3x - x \\ 8 = 2x \\ \frac{8}{2} = x \\ x = 4[/tex]

4.

[tex]x = \frac{x + 5}{2} \\ 2x = x + 5 \\ 2x - x = 5 \\ x = 5[/tex]

We simply multiply the whole equation by 2 to get rid of the denominator.
