Answer:

$x = 3.6$

Step-by-step explanation:

To find the area of a rectangle, you multiply its length by its width. The formula is $lw = a$.

We already know the length, 5, and the area, 18, so we can plug it into the equation.

$5\cdot w=18$

We can simplify this equation by dividing both sides by 5.

$5\cdot w \div5 = 18\div5\\\\w = 3.6$

Which triangle is congruent to the triangle described?
A right triangle has a leg of length 4 and a hypotenuse of length √137.
(1 point)
O (2, 2), (2, -9), (6,2)
O (5,9), (-3,4), (1,4)
O (-8,-2), (-4,-2), (-8,8)
O (2.-10), (-8,-10), (-8,-4)

Answers

Option (a) is the correct one.

By SSS congruence rule the triangle having coordinates (2, 2), (2, -9), (6,2) is congruent to the given triangle as all three sides are equal of both the triangles.

Given, a right angled triangle having base 4 and hypotenuse √137.

Now, we have to find the triangle which is congruent to the given triangle.

So, the height of the given triangle be,

h² = √137² - 4²

h² = 137 - 16

h² = 121

h = √121

h = 11

Now, from the options we can say that,

the triangle having coordinates (2, 2), (2, -9), (6,2) is congruent to the given triangle as all three sides are equal of both the triangles.

Hence, by SSS congruence rule the triangle having coordinates (2, 2), (2, -9), (6,2) is congruent to the given triangle as all three sides are equal of both the triangles.

If a student spent $100 on materials, how much would they spend on books and lab manuals?

Answers

The student would spend $18 on books and lab manuals.

How much is spend on books and lab manuals?

An expenditure refers to the spending of money on something or the money that is spent on something.

Total Expenditure = Lab fee + Materials fee + Tuition + Books and lab manuals + Tools

Total Expenditure = 8% + 10% + 38% + 18% + 26%

Total Expenditure = 100%

We will calculate the amount spent on books and lab manuals. The amount spent on books and lab manuals is:

= (Books and lab manuals percentage / Total Expenditure percentage) * $100

= (18% / 100%) * $100

= 0.18 * $100

= $18.

Step-by-step explanation:

11- 1 obtuse angle because the other 2 need to be acute to connect 3 sides.

12- x=20 degrees because of the other 20 degree angle opposite to it. y=64 degrees because 180-(20+96)=64 (all angles in a triangle add to 180). z=116 degrees because supplementary angles add to 180 degrees and Y and Z are supplementary.

By considering these rules and properties of integers, the correct result of 6 was obtained.

When writing the response, I considered the following information:

The product or quotient of two integers with different signs is negative. This rule was used to determine that 2(-12) equals -24, not 24.

To subtract an integer, add its opposite. This rule was applied when subtracting -30 from -24, resulting in -24 - (-30) = -24 + 30.

To add integers with opposite signs, subtract the absolute values. The sum has the same sign as the integer with the greater absolute value.

This rule was used to calculate -24 + 30 = 6, where the absolute value of 30 is greater than the absolute value of -24.

By considering these rules and properties of integers, the correct result of 6 was obtained.

the ratio of dogs to cats is 5 to 3, if there are 14 more dogs than cats, how many animals are there altogether?

Answers

Answer:

Step-by-step explanation:

D/C=5/3, so 3D=5C. 14+C=D is the second equation, so now you can solve for each.

3D=5C, 14+C=D
D=(5/3)C
14+C=(5/3)C
14=(2/3)C
C=21

21+14=D=35

So there are 21 cats and 35 dogs, or 56 total animals.

Lin is paid $90 for 5 hours of work. She used the table to calculate how much she would be paid at this rate for 8 hours of work

Answer: $144

Step-by-step explanation: To find the price she gets paid for 1 hr we need to divide the money by the hours. So, 90 / 5 = 18.

So, now we know she gets paid 18 dollars an hour. So, we need to find out how much she earns in 8 hrs. So, we would simply multiply the 18 by the 8, to get $144.

A small data analysis class has five computer science majors among the twenty-three total students. four people are chosen at random to form a group. let x denote the number of computer scientists in this group.
a. Fin E(X)
b. Find Var(X)

Answers

The value of E(x) is 0.8695 and Var(x) is 0.5877

How to determine the value of E(x)

From the question, we have the following parameters that can be used in our computation:

n = 23

x = 4

k = 5

The value of E(x) is calculated as

E(x) = xk/N

Substitute the known values in the above equation, so, we have the following representation

E(x) = 4 * 5/23

E(x) = 0.8695

How to determine the value of Var(x)

This is calculated as

Var(x) = E(x) * (1 - k/n) * ([n - x]/[n - 1])

Substitute the known values in the above equation, so, we have the following representation

Var(x) = (4 * 5/23) * (1 - 5/23) * ([23 - 4]/[23 - 1])

Var(x) = 0.5877

Estuary provides refuge after dam removal for bull troutBull trout use a bewildering array of strategies to aid in their survival, from remaining in streams their whole lives, like rainbow trout, to spending part of their lives in the ocean before returning tostreams to spawn, just as salmon do.Bull trout are present in only one of two neighboring rivers in the Olympic peninsula, Washington state, and in this one (the Elwha River), where two large dams were removed. Dam removal resultedin massive outflow of sediments, reducing the clarity of the water and also building up a large delta and expanding the size of the estuary at the mouth of the Elwha River.Sampling for bull trout before, during, and after dam removal was used to detect whether bull trout changed their use of the Elwha River estuary or moved into the adjacent Salt Creek stream wherethey were formerly absent. Sampling revealed no movement into Salt Creek, but numbers of bull trout in the Elwha River estuary increased greatly during and immediately after dam removal,coinciding with large sediment outflow, before returning to their original low levels. Thus, bull trout appear to have used the enlarged estuary as a refuge from the effects of dam removal, thenreturning to the river when the river water cleared up from the sedimentOf additional interest is the long-term response of bull trout to the additional habitat opened up above the former dams.Lincoln, A.
