Answer:

Your correct, it's C and D

Step-by-step explanation:

A and E are right triangles, so that's not the answer. B and F are isosceles triangles so that's not the answer. C and D are 2 DIFFERENT obtuse triangles so that's why C and D are the answers.

Answer:

D) 81x²y¹⁰

Step-by-step explanation:

(9xy⁵)²

Because all of 9xy⁵ are in the parentheses, each component is raised to the 2nd degree.

(9)² = 81

(x)² = x²

(y⁵)² = y¹⁰ -- When you raise an exponent to another exponent, you multiply the exponents.

Now combine the components.

D) 81x²y¹⁰

Answer:

s(3)=11

Step-by-step explanation:

s(t)=t^3-8t+9

Plug in 3 for t

s(3)=(3)^3 - 8(3) + 9

s(3)=27 - 24 +9

s(3)=11

Answer:

14

Step-by-step explanation:

It says 'Evaluate (y - 9) + (3 + x), when y = 15 and x = 5​'.

So we'd put 15 in y's place. It'll look like this (15 - 9).

Then we'd put 5 in x's place. It'll look like this (3 + 5).

You subtract (15 - 9) which equals 6. And you'd add (3 +5) which equals 8. You add 6 + 8 together since those are your answer for the parentheses. Your final should be 14. Hopefully this helped!

Answer:

(-0.5,7.66)

Step-by-step explanation:

2x+6y=21

-2x+3y=24

so 3y=24+2x

reduce

y=(24+2x)/3

substitute for y

2x+6(24+2x/3)=21

2x+(72+12x)/3=21

2x+24+4x=21

6x=-3

x=-0.5

y=(24+-1)/3=7.66

Answer:

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of independent events:

Suppose we have two events, A and B, that are independent. The probability of both happening is given by:

[tex]P(A \cap B) = P(A) \times P(B)[/tex]

In this question:

Event A: Selecting a prime number.

Event B: Selecting a number less than or equal to 3

Probability of selecting a prime number:

Between 1 and 10, we have 4 prime numbers(2,3, 5 and 7), out of 10. So

[tex]P(A) = \frac{4}{10}[/tex]

Probability of selecting a number less than or equal to 3:

Three numbers(1,2,3) out of 10. So

[tex]P(B) = \frac{3}{10}[/tex]

Probability of both:

[tex]P(A \cap B) = P(A) \times P(B) = \frac{4}{10} \times \frac{3}{10} = \frac{12}{100} = 0.12[/tex]

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Answer:

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

Answer:

Dividing by fractions is just like multiplying fractions, except for one additional step. To divide any number by a fraction: First step: Find the reciprocal of the fraction. Second step: Multiply the number by the reciprocal of the fraction. Third step: Simplify the resulting fraction if possible.

Answer:

Explanation:

-12.4x + 8x > -0.4x - 5.2 - 2.7

Add similar elements: -12.4x + 8x = -4.4x

-4.4x > -0.4x - 5.2 - 2.7

Subtract -5.2 - 2.7: -7.9

-4.4x > -0.4x - 7.9

Multiply both sides by 10

-4.4x · 10 > -0.4x - 7.9 · 10

Refine

-44x > -4x - 79

Add 4x to both sides

-44x + 4x > -4x - 79 + 4x

Simplify

-40x > -79

Multiply both sides by -1 (Reverse the inequality)

-40x (-1) > -79 (-1)

Simplify

40x < 79

Divide both sides by 40

40x / 40 < 79 / 40

Simplify

x < ⁷⁹⁄₄₀

Turn the fraction into a decimal

Answer:

(2,4)

Step-by-step explanation:

Replace all occurrences of  y  with  3 x − 2  in each equation.

3x - 4 = x

y= 3x -2

Solve for  x  in the first equation.

x = 2

y = 3x - 2

Replace all occurrences of  x  with  2  in the equation.

y = 4

x= 2

The solution to the system is the complete set of ordered pairs that are valid solutions.

(2,4)

Answer:

29.9 °F

Step-by-step explanation:

The formular for mean is given as;

Mean = Sum of Terms / Number of terms

Number of terms = 6

Sum of terms = 35.5  + 30.8  + 27.3  + 32.1  + 23.8  + 29.9 = 179.4

Mean = 179.4 / 6 = 29.9

4,000 CM^2

first you multiply 8 by 5 to find out the square meters then you Multiply 100 because that's how many centimeters are in a meter and that equals 4,000.

Answer:

Side XY is 6 units

Step-by-step explanation:

The order of ∆ QRS will be the same as the order of ∆ XYZ and the corresponding order between the 2 are congruent.

Angle Q is congruent to angle X because they are listed first. Angle R is congruent to angle Y because they are listed second. Angle S is congruent to angle Z because they are listed third.

We can see that side QR is 6 units. The corresponding side on triangle XYZ is side XY.

These triangles are congruent under the SAS congruence criterion. We can prove it using the following steps :

Given :

In triangle 1 and 2 :

Since the SAS congruence criterion says that two triangles are congruent if two of their sides and one included angle is equal and since these 2 triangles fulfill all of those rules, we can conclude that these triangles are congruent under the SAS congruence criterion.
