Answer:

SSS - The two triangles share all 3 sides, proving they are congruent.

Step-by-step explanation:

Two sides of each triangle are marked in the diagram as equal. The third side, [tex]\overline{BD}[/tex] is shared between both sides, meaning that both triangles share all three sides. This is known as SSS (side-side-side) and is a proof of congruence.

Step-by-step explanation:

In triangle ABD In triangle CBD

AB. = BC. [Given]

AD. = CD. [Given]

BD. = BD. [Common side]

Therefore,

According to SSS Congruence condition

Triangle ABD is congruent to Triangle CBD

Answer: 36 and 22 A=396

Step-by-step explanation:

half of 1 diagonal is 18, so the whole diagonal is 36

the other diagonal half is 11 so the whole is 22

put 36 and 22 into the boxes

then solve

[tex]A=\frac{1}{2} (36*22)\\A=396[/tex]

Answer:

A = 99 in²

Step-by-step explanation:

Using the given formula with d₁ = 18 and d₂ = 11 , then

A = [tex]\frac{1}{2}[/tex] × 18 × 11 = 9 × 11 = 99 in²

Answer:

522 m^2

Step-by-step explanation:

I've circles the numbers that you actually need to solve this problem.

First, find the area of the bigger rectangle by multiplying the length and width.

24*21=504

Then find the area of the smaller rectangle the same way

3*6=18

then add them to get the total area

504+18=522

522 m^2

Answer:

Future population in 19 years = 3,254,580 people (Approx.)

Step-by-step explanation:

Given:

Current population of city = 900,000

Growth rate of population = 7%

Number of year = 19

Find:

Future population in 19 years

Computation:

A = P[1+r]ⁿ

Future population = Current population[1+g]ⁿ

Future population in 19 years = 900,000[1+7%]¹⁹

Future population in 19 years = 900,000[1+0.07]¹⁹

Future population in 19 years = 900,000[1.07]¹⁹

Future population in 19 years = 900,000[3.6162]

Future population in 19 years = 3,254,580

Future population in 19 years = 3,254,580 people (Approx.)

Answer:

B (5t + 15 ≤ 140) is correct

Step-by-step explanation:

Because since each table (t) seats 5 people, you'd represent that as 5t (5 seats per table).

Since there is one extra table that seats 15 people, you'd represent that as 15.

Lastly, those two last steps added together should have to be less than or equal to (≤) 140 (the amount of people allowed in the building).

Answer:

false

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

To calculate the area of a circle you need to multiply the radius by itself, then multiply that number by [tex]\pi[/tex].

In this case, our radius is 3, so we multiply 3 × 3 × [tex]\pi[/tex] (which can be estimated as 3.14)

3×3 is 9

9×3.14 is 28.26

28.26≠18.84

So, the correct answer is false. Hope this helps ^.^

Answer: (-2, 11/6)

Step-by-step explanation:

Answer:

5. 10 cm

6. 12 in

7. 5 mi

8. 13 cm

Step-by-step explanation:

5. 6² + 8² = x²

36 + 64 = x

36 + 64 = 100

√100 = 10

6. 15² - 9² = x²

225 - 81 = 144

√144 = 12

7. 3² + 4² = x²

9 + 16 = x

9 + 16 = 25

√25 = 5

8. 12² + 5² = x²

144 + 25 = x

144 + 25 = 169

√169 = 13

Step-by-step explanation:

if there are 40 students in all and the ratio is 3:5 that means there are 2 more girls than boys and 2 less boys than girls so that means there are 22 girls and 18 boys in the classroom.

Answer:

The test statistic for Norah's test is [tex]t = -2[/tex]

Step-by-step explanation:

Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml.

This means that at the null hypothesis we test if the sample mean is 500 ml, that is:

[tex]H_0: \mu = 500[/tex]

At the alternate hypothesis, we test if it is differente than 500 ml, that is:

[tex]H_a: \mu \neq 500[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

500 is tested at the null hypothesis:

This means that [tex]\mu = 500[/tex]

She takes a random sample of 16 bottles and finds a mean amount of 497ml, and a sample standard deviation of 6ml.

This means that [tex]n = 16, X = 497, s = 6[/tex]

Calculate the test statistic for Norah's test.

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{497 - 500}{\frac{6}{\sqrt{16}}}[/tex]

[tex]t = -2[/tex]

The test statistic for Norah's test is [tex]t = -2[/tex]

Answer:

look at the picture i sent......

Answer:

Equation:y = 1/2x .  or x = 2y

Constant = 2

Step-by-step explanation:

Input y = output x

the first input/output says that when inputed 2, the number 1 is outputted.

Similarly, when 5 is inputted, 2.5 is the output.

1/2 = 2.5/5

That means that y = 1/2 x

or x = 2y

Answer:

X (15, −8) → X ′(9, −3) → X ″(9, 3);

Y (13, 21) → Y ′(7, 26) → Y ″(7, −26);

Z (−17, 17) → Z ′(−23, 22) → Z ″(−23, −22)

Step-by-step explanation:

Use the translation vector <−6, 5>  to determine the rule for translation of the coordinates: (x, y)→ (x+(−6),y + 5).

Apply the rule to translate vertices X(15 ,−8), Y(13, 21) , and Z(−17, 17) .

X (15,−8) → (15 + (−6),−8 + 5) → X'(9, −3).

Y (13, 21) → (13+ (−6), 21 + 5) → Y' (7, 26).

Z (−17, 17) → (−17 + (−6), 17 + 5) → Z' (−23, 22).

To apply the reflection across x-axis use the rule for reflection: (x, y) → (x, −y).

Apply the reflection rule to the vertices of △X'Y'Z'.

X' (9, −3) → X'' (9, 3).

Y' (7, 26)→Y''(7, −26).

Z' (−23, 22) → Z'' (−23, −22).

Therefore,

X (15 ,−8) → X' (9, −3) → X'' (9, 3)

Y (13, 21) → Y' (7, 26) → Y'' (7, −26)

Z (−17, 17) → Z' (−23, 22) → Z'' (−23, −22)

represents the translation of △XYZ along vector <−6, 5>  and its reflection across the x-axis.

Step-by-step explanation:

Answer:

pumpkin because it got the most sold

Answer:

9

Step-by-step explanation:

Knowing that

pumpkin = 6

Total =

​chocolate cupcakes 2 + ​pistachio cupcakes ​ 1 + ​banana cupcakes ​ 5 +​pumpkin cupcakes ​ 6

Thus, 2 + 1 + 5 + 6 = 14

Cross multiply

[tex]\frac{6}{14}=\frac{x}{21}[/tex]

6 * 21 = 126

126/14 = 9

Hence, next 21 cupcakes sold that will be pumpkin cupcakes will 9 pumpkin cupcake

Answer:

D. Graph D

Step-by-step explanation:

I calculated it logically

The correct option is D)The p-value falls between 0.005 and 0.01.

What is p-value?

The P value denotes the probability that, when the null hypothesis is true, the statistical summary will be equal to or more extreme than the actual observed results for a specific statistical model.

The given that [tex]H_0[/tex]: μ = 1.6 and  [tex]H_a[/tex]: μ ≠ 1.6.  and n=28.

Degrees  of freedom = n-1 = 28-1 = 27 This is two tailed test,

P(t>2.79)=1-P(t<2.79)

=> 1-0.9952

=> 0.0048.

P-value = 2*P(t>2.79)=2*0.0048=0.0096.

Hence the correct option is D)The p-value falls between 0.005 and 0.01.
