I Need Help I Dont Understand This

Answers

Answer 1

Answer:

Step-by-step explanation:

lets say "a" for the empty line,

for small triangle; y^2 = 2^2 + x^2

right triangle; we say a for empty line, a^2= 6^2 + x^2

and big triangle covering both triangles, 8^2 = y^2 + a^2

lets add left sides and right sides in each;

x^2 + 4 + x^2 + 36 + y^2 + a^2 = y^2 + a^2 + 64 and we can delete same things for both sides

y^2 and a^2 can be deleted and 4+36 - 64

2(x^2)=24

x^2= 12

and x will be √12

so, y^2 = x^2 + 2^2 which means y^2 = 12+4 y=16

Answer:

x < - 4/5

Step-by-step explanation:

Given the inequality:

4x +4< 9x +8

Collect like terms :

4x - 9x < 8 - 4

Divide both sides by - 5

-5x / - 5 < 4 / - 5

A computer’s random number generator produces random integers from 1 to 50. What is the probability that the first 3 integers generated are single-digit numbers?


0.0058

0.0080

0.5120

0.5514

Answers

Answer:

0.0058

Step-by-step explanation:

Probability is defined as the ratio of the possible outcome to the total outcome. The number of single-digit numbers between 1 and 50 is 9 ( from 1 to 9). As such, the probability of generating a single digit integer is

P(single) = 9/50

The probability that the first 3 integers generated are single-digit numbers

= 9/50 * 9/50 * 9/50

= 0.18 * 0.18 * 0.18

= 0.005832

This may be approximated to 0.0058

The question is incomplete. Here is the complete question.

m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.

If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.

A. 1

B. 154

C. 77

D. 26

Answer: B. m∠K = 154

Step-by-step explanation: Isosceles trapezoid is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.

Related to internal angles, angles of the base are equal and opposite angles are supplementary.

In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:

18x + 8 = 11x + 15

7x = 7

x = 1

Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:

m∠J = 18(1) + 8

m∠J = 26

m∠K + m∠J = 180

m∠K + 26 = 180

m∠K = 154

The angle m∠K is 154°

A family of 4 is buying cell phones. Each phone costs x dollars if the family buys the super plan which costs $89 for

each family member. The total cost for each family member to have a phone with the super plan is $1,952

Part A

Which equation represents this situation?

O4(2 + 89) = 1,952

O (x + 89) + 4 = 1,952

4x + 89 = 1,952

O 4x(89) = 1,952

Part B

What is the cost, in dollars, of each phone?

Each phone costs $

Ya

Answers

Answer: See explanation

Step-by-step explanation:.

From the question, the equation to illustrate the above question will be:

4(x + 89) = 1952

We can then solve further to get the value of x which will be:

4x + 356 = 1952

4x = 1952 - 356

4x = 1596

x = 1596/4

x = 399

Each phone cost $399

Find x if:
- B is between A & C;
-AB = x + 5;
-BC = 2(x-3); and
-AB ~= BC

Answers

Answer:

The value of x = 11

Step-by-step explanation:

Given

B is between A and C.AB = x+5BC = 2(x - 3)[tex]{\displaystyle {\overline {AB}[/tex] ≅ [tex]{\displaystyle {\overline {BC}[/tex]

Determining the value of x

As B is between A and C, so

[tex]{\displaystyle {\overline {AB}[/tex] ≅ [tex]{\displaystyle {\overline {BC}[/tex]

as

AB = x+5BC = 2(x - 3)

so

x + 5 = 2(x-3)

x+5 = 2x-6

2x-x = 5+6

x = 11

Therefore, the value of x = 11

What proportion represents the percent of
strike outs per at bats?

Answers

Answer:

p = 31.19%

Step-by-step explanation:

Proportions and Percentages

A proportion is calculated as a division between two numbers. The result can be given as a decimal or as a percentage.

If we want to calculate the percent of a number N with respect to another number M, the formula is:

[tex]\displaystyle p=\frac{N}{M}*100\%[/tex]

Eli had some performances when playing baseball. Struck out 25 times in 75 times at bat, 30 times in 100 at-bats, and 37 times in 120 at-bats.

The total struck outs were: N= 25+30+37=92 and the total at-bats were: 75+100+120=295. The proportion of strikeout ber at-bats is:

[tex]\displaystyle p=\frac{92}{295}*100\%[/tex]

p = 31.19%

Step-by-step explanation:

This is due to 2(2) = 4

The solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.

What is exponential function?

An exponential function is a mathematical function of the following form:

[tex]f(x) = a^{x}[/tex]. where x is a variable, and a is a constant called the base of the function.

Given exponential equation

[tex]324=4(3)^{2x}[/tex]

[tex]4(3)^{2x}=324[/tex]

[tex]3^{2x} =\frac{324}{4}[/tex]

[tex]3^{2x}=81[/tex]

[tex]3^{2x}=3^{4}[/tex]

When bases are equal, power should be equal.

2x = 4

x = 2

Hence, the solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.
