Answer:

C

Step-by-step explanation:

To prove that two triangles are congruent using the SSS Congruence criterion, we must establish that all three sides of one triangle are equal to all the corresponding sides of the other.

Thus,

Side AD in ∆ADB is congruent to side AD in ∆ADC.

Side BD in ∆ADB is congruent to side CD in ∆ADC.

Side AB in ∆ADB is congruent to side AC in ∆ADC.

Therefore, based on the SSS congruence criterion, it is concluded that both triangles are congruent.

The statements necessary to prove that they are congruent by SSS is:

Answer:

12 miles

Step-by-step explanation:

Kyle's speed = 2 mph

Steve's speed = 2 mph

Time traveled = 3 hours

Distance apart after 3 hours

Distance moved by Kyle + Distance moved by Steve

Distance = Speed * time

Distance moved by Kyle = 2 * 3 = 6 miles

Distance moved by Steve = 2 * 3 = 6 miles

Total distance apart = 6 + 6 = 12 miles

Answer:

x = 81

Step-by-step explanation:

x = 180 - 99

x = 81

Answer:

a. 1.05

b. 0.95

Step-by-step explanation:

a. 5 percent increase

5% = 0.05

Because it is increasing, so we add 1

1 + 0.05 = 1.05

b. 12 percent decrease

12% = 0.12

Because it is decreasing, so subtract 1

1 - 0.05 = 0.95

So, the answer is

a. 1.05

b. 0.95

Given:

The expression is:

[tex]6x^2+3x+21[/tex]

To find:

The factor of the given expression by GCF.

Solution:

It is given that,

[tex]6x^2+3x+21[/tex]

The terms of the given expression are [tex]6x^2,3x,21[/tex]. The greatest common factor of these terms is 3.

[tex]6x^2+3x+21=3\times 2x^2+3\times x+3\times 7[/tex]

So, taking out the GCF, the given expression can be rewritten as:

[tex]6x^2+3x+21=3(2x^2+x+7)[/tex]

Therefore, the factor form of the given expression by GCF is [tex]3(2x^2+x+7)[/tex].

Step-by-step explanation:

Area of Triangle x 2 = 3 * 3

The reason I did not divide it by 2 is because of how the other triangle is bound to have the same area. Just leave it as it is because later you're going to reach the same answer.

3 * 3 = 9

Rectangle Area = 6 * 3 = 18

Answer: from left to right -3,-1,1,3,5

Step-by-step explanation:

Substitute the x value from the chart into the equation for each number.

If Ojemba is sitting on a sled on the side of a hill inclined at 60° and  weight of Ojemba and sled is 160 pounds , then magnitude of force needed for Mandisa to keep sled from sliding down the hill is 355.59 N   .

the inclination angle of the the side of the hill is = 60° ;

the compound mass of Ojemba and Sled is = 160 pounds ,

On conversion we get the mass in Kg is = 72.57 Kg .

the acceleration due to gravity is , [tex]g = 9.8 m/s^{2}[/tex] ;

The force required for Mandisa to keep sled from sliding down the hill can be calculated by the formula ;

[tex]F = mgSin\theta[/tex] , Substituting the values ,

we get ;

[tex]F = 72.57\times 9.8\times Sin(30\textdegree)[/tex]

[tex]F = 72.57\times 9.8\times \frac{1}{2}[/tex] ;

So , [tex]F = 355.59 N[/tex] .

The required magnitude of the force is 355.59 N .

Answer:

Consecutive odd numbers will be 11 and 13.

Step-by-step explanation:

Let the two consecutive odd integers are n and (n + 2).

From the given question,

Sum between twice the smallest and the biggest is 35.

Since, smallest number is 'n' and biggest is (n + 2)

Therefore equation will be,

2n + (n + 2) = 35

(2n + n) + 2 = 35

3n + 2 = 35

3n = 33

n = 11

And (n + 2) = 13

Consecutive odd numbers will be,

3 1/3 bombones

Explicación paso a paso:

Distribuir 21 bombones entre 5 niños;

21/5 = 4 resto 1

Por lo tanto, se le da 4 chocolates a cada niño y el 1 chocolate restante se divide en 5 partes iguales y se le da 1/5 a cada niño. Por lo tanto, cada niño recibe 4 1/5 chocolates.

Distribuir 10 bombones entre 3 niños;

10/3 = 3 resto 1

Por lo tanto, se le da 3 chocolates a cada niño y el 1 chocolate restante se divide en 3 partes iguales y se le da 1/3 a cada niño. Por lo tanto, cada niño recibe 3 1/3 chocolates.

The value of k⁻¹(8) in for k(x) = 4 ÷ 5x - 6 is 2/35.

First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.

We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.

Given, k(x) = 4 ÷ 5x - 6.

k(x) = (4/5x) - 6.

Let, y = k(x).

y =  (4/5x) - 6.

(4/5x) = y + 6.

1/x = 5(y + 6)/4.

x = 4/{5(y + 6)}.

y = 4/{5(x + 6)}.

k⁻¹(x) = 4/{5(x + 6)}.

k⁻¹(8) = 4/{5(8 + 6)}.

k⁻¹(8) = 4/{5(14)}.

k⁻¹(8) = 4/70.

k⁻¹(8) = 2/35.

Hi there!

We can find the values of x using right triangle trig.

Recall: SOHCAHTOA

sin = O/H (Opposite / Hypotenuse)

cos = A/H (Adjacent / Hypotenuse)

tan = O/A (Opposite / Adjacent)

Thus:

6. A = 14, H = 15

cos x = 14/15

cos⁻¹ (14/15) = x

x = 21.04° ≈ 21°

7. O = 19, A = 23

tan x = 19/23

tan⁻¹(19/23) = x

x = 39.56° ≈ 40°

8. A = 9, H = 17

cos x = 9/17

cos⁻¹(9/17) = x

x = 58.03 ≈ 58°

9. O = 43, H = 45

sin x = 43/45

sin⁻¹(43/45) = x

x = 72.85° ≈ 73°

the value of log2 log32 is 0.5899 and  the base of the logarithm is raised to the value that was equated earlier and this expression is equal to the logarithm.

logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.J

The logarithmic equation that has the same solution as x-4=2^3 is log2(x-4)=3.

Answer:

212

Step-by-step explanation:

The solutions can be read off of the diagonal entries in the reduced matrix.

To solve a 3 x 3 system of equations using matrices, first we need to create the augmented matrix for the system of equations. The augmented matrix contains the coefficients of the variables and the constants for each equation on each row. Then we can use row operations to reduce the augmented matrix to reduced row-echelon form. This can be done by adding or subtracting rows to each other, multiplying or dividing a row by a non-zero number, and swapping two rows. After reducing the matrix to row-echelon form, we can back-substitute the solutions to the system of equations. The solutions can be read off of the diagonal entries in the reduced matrix. For example, if the matrix is reduced to the form [a b c d e f g h i] then the solution to the system of equations is x = d/a, y = e/b, and z = f/c.
