Answer:

x =11

Step-by-step explanation:

XWY + YXZ = XWZ

5x+5 + 2x+8 = 90

Combine like terms

7x+ 13 = 90

Subtract 13 from each side

7x= 90-13

7x = 77

Divide by 7

7x/7 = 77/7

x = 11

4. Square ABCD is shown. What is the length of diagonal AC? Round to the nearest tenth, if necessary.

Answers

Answer:

hey! You have to use the trigonometric formula because it's a rectangle triangle:

(a^2)+(b^2)=(c^2)

(11^2)+(11^2)=(c^2)

√(242)=√(c^2)

15.56=c

So basically, the answer is D!

The square ABCD has equal sides, and the length of the diagonal AC is 15.6 centimeters

How to determine the length of the diagonal?

The side length of the square is given as:

l = 11 cm

The length of the diagonal is calculated using:

Diagonal = l * √2

This gives

Diagonal = 11 * √2

Evaluate

Diagonal = 15.6

Hence, the length of the diagonal AC is 15.6 centimeters

Answers

Answer:

x = 3, y = 6, z = 4

Step-by-step explanation:

If lines s, t, and u are perpendicular bisectors of the sides of APGH and meet at J, then JG = JH = JF = HI

Given

JG - 2x+ 2

JH - 2y-4

JF-8 a

HI - 3z-3,

Hence 2x+2 = 2y-4 = 3z-3 = 8

This means that

2x+2 = 8

2x = 8-2

2x = 6

x = 3

Also, 2y-4 = 8

2y = 8+4

2y = 12

y = 6

And 3z-3 = 8

3z = 8+3

3z = 11

z = 11/3

z = 3.67 ≈ 4

Hence x = 3, y = 6,z = 4

Answers

Answer:

77 degrees.

Step-by-step explanation:

All triangles equal up to a measure of 180 degrees.

If one side is 26 degrees, and the other sides are congruent, meaning the same, then:

1. 180-26 = 154

2. 154/2 = 77

The measures of the other sides are 77 degrees.

Write a compound inequality that represents the Fahrenheit temperatures between 50 degrees Celsius and 70 degrees Celsius.

Answers

Answer:

122 ≤ F ≤ 158

Step-by-step explanation:

First we convert the Celsius temperature to Fahrenheit

Mathematically, the formula to use is as follows;

F = 9/5C + 32

So 50 will be;

F = 9/5(50) + 32 = 90 + 32 = 122

70 will be

F = 9/5(70) + 32 = 126 + 32 = 158

So the inequality will be;

122 ≤ F ≤ 158

a ratio of angel fish at a store is 5:4. the ratio of angel fish to goldfish is 4:3 . There are 60 clown fish at the pet store
how many angel fish are there?
how many goldfish are there

Answers

Answer:

an i oop

Step-by-step explanation:

Answer:

So if there are 60 clownfish and the ratio from clownfish to angelfish is 5:4, this is the equation you are looking at:

5:4 = 60:?

To find ? you have to do 60 divided by 5 which equals 12 and multiply it times 4 to see how many angelfish there will be if there are 60 clownfish.

12 x 4 = 48

So if there are 60 clownfish there will be 48 angelfish. The ratio is 60:48

For the next one, same thing if there are 48 angelfish, then you are looking at this equation:

4:3 = 48:?

Again, we solve like we did the last one.

48 divided by 4= 12

3 x 12= 36

So, if there are 48 angelfish there will be 36 goldfish. The ratio is 48:36

Determine if the sequence is arithmetic or geometric, and find the common difference or ratio.

x 1 2 3 4
f(x) 5 −5 −15 −25
Arithmetic, common difference = −10
Arithmetic, common difference = −1
Geometric, common ratio = −10
Geometric, common ratio = −1

Answers

Answer:

The correct option is;

Arithmetic, common difference = -10

Step-by-step explanation:

The x terms given of the sequence are;

x [tex]{}[/tex] 1 2 3 4

f(x) [tex]{}[/tex] 5 -5 -15 -25

For a geometric progression, a·r/a = a·r²/ar = ar³/ar² = (n + 1)/n = r

We check to obtain -5/5 ≠ -15/(-5), therefore, the system is not a geometric progression

For ab arithmetic progression, we have;

(n + 1)th term - nth term = (n + 2)th term - (n + 1)th term = d (The common difference

We check to obtain -5 - 5 10, -15 - (-5) = -15 + 5 = -10 similarly, we have; -25 - (-15) = -25 + 15 = -10

Therefore, the sequence is an arithmetic sequence, with common difference = -10.
