Answer:

we use the ASA when a triangle is conguerent by angle,side,angle.

SAS se when atriangle is conguerent by side,angle,side

sss when the triangle is conguerent by side,side,side

Answer:

ASA- The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

SAS- is a rule used to prove whether a given set of triangles are congruent. The SAS rule states that: If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, then the triangles are congruent.

SSS- If two triangles are congruent it means that all corresponding angle pairs and all corresponding sides are congruent. The SSS criterion for triangle congruence states that if two triangles have three pairs of congruent sides, then the triangles are congruent

Answer:

CSA of a cylinder = 144cm²

Step-by-step explanation:

Given the following data;

Base circumference = 36cm

Height = 4cm

To find the curved surface area (CSA) of the cylinder;

CSA of a cylinder = 2πr * h

But 2πr = 36cm

Substituting the values into the equation, we have;

CSA of a cylinder = 36 * 4

CSA of a cylinder = 144cm²

Answer:

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle. Your best bet when learning/visualizing word problems is to draw a picture, then learn how to visualize in your head over time.

[tex]3^2+x^2=12^2\\9+x^2=144\\x=\sqrt{135}[/tex]

The radical can be further simplified because 135 is the product of 9 and 15. 9 has a perfect root of 3.

[tex]x=3\sqrt{15}[/tex] meters or 11.62 meters

Step-by-step explanation:

step 1. properties of equality have an "=" in the equation.

step 2. properties of inequality have a <, <=, >=, or a >.

Step-by-step explanation:

step 1. x > -2 means numbers greater than -2 but not including -2.

step 2. you graph a single variable on a number line.

step 3. the graph would include an open circle above -2 (not equal to -2)

step 4. the line would go right of the open circle (greater than) and have an arrow at the end.

step 5. the answer is b.

Answer:

a) $53.34

b) 84,360.9 gallons

Step-by-step explanation:

let 'x' = cost of bill for 30,000 gallons

a) i set up a proportion as follows:

$1.33/748g = x/30,000

i cross-multiplied and got $53.34

b) i set up a proportion as follows:

let 'y' = how many gallons $150 can buy

$1.33/748g = 150/y

i cross-multiplied and got 84,360.9 gallons

Answer:

About 5043.58

Step-by-step explanation:

The standard form for an exponential decay after t time is:

[tex]\displaystyle f(t)=a(r)^{t/d}[/tex]

Where a is the initial value, r is the rate decay, t is the time that has passed, and d is the amount of time it takes for 1 cycle.

The initial value is 9800. So a = 9800.

The quantity cuts in half. So, r = 1/2.

And it cuts in half every 6 days. For this question, we will convert this to hours. 6 days = 144 hours. So, we can let d = 144, where t will be in hours.

Therefore, our function is:

[tex]\displaystyle f(t)=9800\Big(\frac{1}{2}\Big)^{t/144}[/tex]

Where t is the amount of time that has passed, in hours.

Then the quantity left after 138 hours will be:

[tex]\displaystyle f(138)=9800\Big(\frac{1}{2}\Big)^{138/144}\approx 5043.58[/tex]

50% off makes the new price half of the original, then another 50 % would be half off the discounted price, so they actually end up paying 25 % of the original price:

50 % x 50 % = 25 %

Answer:

she was charged for 50% of the 50% off

Step-by-step explanation:

Lets say the original price was 100$ The store discounted it by 50% so it is now 50$ but the coupon take 50% off of that 50 so it would be 25$

Answer:

[tex]Ratio = 2:3[/tex]

Step-by-step explanation:

Given

[tex]Cards = \{2,5,7,8,9,11\}[/tex]

Required

Ratio of odd numbers to total

First, list out the odd numbers

[tex]Odd = \{5,7,9,11\}[/tex]

The card has 4 odd numbers out of a total of 6.

So, the ratio is:

[tex]Ratio = Odd : Total[/tex]

[tex]Ratio = 4:6[/tex]

Divide by 2

[tex]Ratio = 2:3[/tex]

Hence, the ratio of odd to total is 2 to 3

The width is 3.

A rectangular prism is 3d. This means that there are three dimensions being multiplied by each other to obtain the overall volume. We can use the equation V = lwh to solve this equation, with V being volume, and the following, length, width, height. Substituting in the values (and changing the mixed numbers to improper fractions for simplicity):

1035/4 = (15/2)(23/2)(w)

w = (1035/4)(2/15)(2/23)

w = 3

Step-by-step explanation:

Answer:

3/1 or 3

Step-by-step explanation:

7 1/3  = 7x3 + 1/3 =21 + 1/3 =22/3

7x3/3 = 21/3

-------------------------------------------------

2 4/9 2x9 + 4/9 = 18 + 4 /9= 22/9

2x9/9 = 18/9

Divide: 22/3 : 22/9 =22/3 x9/22 =

22/3 x 9/22 = 198/66 66/66 x 3/1 = 3

Answer:

[tex]y = 1125x+30000[/tex] --- The equation

The median income in 2030 is $75000

Step-by-step explanation:

Given

Represent years since 1990 with x and the income with y.

So, we have:

[tex](x_1,y_1) = (0,30000)[/tex] --- In 1990

[tex](x_2,y_2) = (16,48000)[/tex] --- In 2006

Solving (a): Express as a function.

First, we calculate the slope

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

[tex]m = \frac{48000-30000}{16-0}[/tex]

[tex]m = \frac{18000}{16}[/tex]

[tex]m = 1125[/tex]

The equation is then calculated as:

[tex]y = m(x-x_1)+y_1[/tex]

This gives:

[tex]y = 1125(x-0)+30000[/tex]

Open bracket

[tex]y = 1125x-0+30000[/tex]

[tex]y = 1125x+30000[/tex]

Solving (b): Income in 2030.

In 2030, x = 40.

Substitute 40 for x in [tex]y = 1125x+30000[/tex]

[tex]y = 1125*40 +30000[/tex]

[tex]y = 45000 +30000[/tex]

[tex]y = 75000[/tex]

Solving (c): The significance of the slope.

In (a), the slope is calculated as 1125.

This implies that the yearly rate is $1125

Answer:

84

Step-by-step explanation:

Let the third term be x.

So, the numbers will be:

24, 36, x, 126

Since, all the four terms are in proportion.

Therefore,

[tex] \frac{24}{36} = \frac{x}{126} \\ \\ x = \frac{24 \times 126}{36} \\ \\ x = \frac{3,024}{36} \\ \\ x = 84[/tex]

Answer:

The mean is 8.4

Step-by-step explanation:

First you find the class centers.

3-6 = 4.5

7-10 = 8.5

11-14 = 12.5

15-18 = 16.5

The sum of all the scores = 4.5 * 7 + 8.5 * 10 + 12.5 * 6 + 16.5 + 2 = 210

The sum of the number of scores = 7 + 10 + 6 + 2 = 25

The mean = 210/25 = 42/5 = 8.4

Answer:

(c) [tex]h(3) = 1[/tex]

Step-by-step explanation:

Given

The attached graph

Required

Find h(3)

The formula to use in solving this is:

[tex]y = h(x)[/tex]

Substitute 3 for x

[tex]y = h(3)[/tex]

From the attached graph, the value od x = 3 points to the value of y = 1.

So, we have:

[tex]y = 1[/tex]
