Answer: 1. 55 ft   2. 10 ft. 3.3 in.

Step-by-step explanation:

For question 9, you need to understand that the angle on the left is equal to the one on the right from the mirror priniciple. Now let's say the height of the dinosaur is x ft. We would get the equation 5.5/4 = x/40 and we get that x is 55, thus the height of the dinosaur is 55 ft

For question 10, we use the same similarity principle as we use in question 9 so given that the height of the light pole is h in. we get the equation

h/185 = 62/93

So, h is 123.33(I used a calculator, hope that's fine). Thus the height of the light pole would be 123.33 in. or 10 ft. 3.3 in.

Hope this helps!!!!

"For 75 g butter ≈ 27 fingers

Step-by-step explanation:

Using unitary method

For 20 fingers = 55 g butter

For 1 g butter = 20/55 fingers

=> For 1 g butter = 4/11 fingers (Simplified form)

Multiplying both sides by 75

=> for 75 g butter =

Answer:

6 $1 bills, 5 $5 bills

Step-by-step explanation:

Say the student has x $1 bills.

Then they have 11 - x $5 bills.

31 = 1 * x + (11 - x) * 5 = 55 - 4x

4x = 55 - 31 = 24

x = 6

So, they have 6 $1 bills and 11 - 6 = 5 $5 bills

Answer:

5, 5, 5, 5, 5, 1, 1, 1, 1, 1, 1. As you see those are eleven numbers/bills so your answer may be, The student has 5, 5$ bills and 6, 1$ bills. which makes up 31$.

Answer:

A to B = 2000 m/s

C to D = 30,000m/s

Step-by-step explanation:

A to B is 10secs and the distance is 200m so you multiply them and you get 2000m/s

C to D is 60secs and the distance is 500m so you multiply and you get 30,000m/s

Answer:

a to b is 20m/s I'm in k12 and I got the same question but I don't know for c to d yet

Answer:

There are 18 yellow marbles in the bag.

Step-by-step explanation:

Let total marble be x,

3/5 of x = 27

or, 3x = 135

so, x = 45

Total = 45

Now,

yellow marbles = 45 - 27 = 18

if 24 cards = $12, 1 card = $2 (24 / 12)

dozen = 12

if half of 24 is 12, and 24 cards cost $12, half of 12 is 6. same goes for the price. $12 / 2 = 6.

==================================================

Explanation:

Focus on the first row only. We won't worry about the other stocks.

Convert each of the percentages to decimal form

Then multiply those decimal values with their respective gains or losses.

Use a negative sign to indicate losses.

The last step is to add up each of the results to get the expected value.

-10+0.75+20.25 = 11

The result is positive, so it's a gain rather than a loss.

On average, we expect an $11 gain for stock ABC.

Answer:

Jack's fathers work is 1350 miles away from home

Step-by-step explanation:

Equation for trip 1:

Usual speed=x

Time=30 minutes

Formula for distance: d=st

d=30x

Equation for trip 2:

Speed= x-30

Time=90 minutes

d=90(x-30)

Now we solve for x using simultaneous equations:

30x=90(x-30)

x=45

Now to find d we sub in our new found value into one of the two equations (it doesn't matter which one)

d=30(45)

d=1350 miles

Answer:  46 degrees

Explanation:

Angle PRS = 98 degrees

The two smaller pieces add up to this larger angle, so,

(anglePRQ) + (angleQRS) = angle PRS

(3x-8) + (2x+6) = 98

5x-2 = 98

5x = 98+2

5x = 100

x = 100/5

x = 20

Then we can find each angle

Notice how 52+46 = 98 to confirm the answers.

Answer:

y = 11

Step-by-step explanation:

A horizontal line passes through every single x - value, but only 1 y - value.

A vertical line hits every y-value and only 1 x-value.

The only y-value given is 11, so the equation is y = 11

-Chetan K

Answer: c because the y intercept is the only correct one, not only that, if you plug in 4 as x in the equation, the y value would be -2 and that ordered pair fits on the line in the graph

Answer:

$90.18 dollars

Step-by-step explanation:

Given the following question:
Original cost = $83.50
Sales tax = 8%

In order to find the price paid for the chair, we find 8 percent of the original price. Then we add that number to the $83.50 for the chair and then we will have our answer.

[tex]\frac{8\times83.5}{100} =8\times83.5=668\div100=6.68[/tex]

Sales tax of the chair is $6.68.

[tex]83.50+6.68=90.18[/tex]

Total cost of the chair after an 8 percent sales tax is "$90.18 dollars."

Hope this helps.

Answer:

Step-by-step explanation:

when there are two subtraction signs it is basically a plus sign

so

___ + 99 = 3

then you can subtract 99 from both sides

___ = -96

your answer is -96

Answer:

x = 7.48

Step-by-step explanation:

You need to use the Pythagorean theorem to solve this problem.

leg^2 + leg^2 = hypotenuse^2

a^2 + b^2 = c^2

5^2 + x^2 = 9^2

25 + x^2 = 81

subtract 25 from both sides.

x^2 = 81 - 25

x^2 = 56

Square root both sides.

x = sqroot(56)

x = 7.48

Answer:

Tom should use a ladder that is smaller or at the the same height of the window frame. Here it says that he is using a ladder that is taller than the window frame, and this can be very uncomfortable for the person who is using the ladder, so it would be recommendable for Tom to use a smaller ladder, probably a ladder that is only a few inches smaller or taller than the window frame. Using a ladder that is like this should be safe to use.

The phrase "no more than" implies upper limit. The correct choice for food budget is: Option D. No more than $60 can be spent on food.

Suppose that you had initial amount as A.

Let you deduce B, C, and D from it.

The remaining amount is obtained by subtraction.

Thus,

Remaining amount  = A - (B + C + D) = A - B - C - D

For the given case, the budget left for food is the remaining amount after all the expenses are reduced from the income.

Income = $750

Expenses except food: $20 + $75 + $85 + $260 + $250 = $690

Thus, budget left is $750 - $690 = $60

This remaining budget is left. The person can spent either full of it on food or less than it, but cannot spend more than it as that person doesn't have more than $60 left.

Thus:

Food budget is no more than $60.

or

Food budget ≤ $60

Thus,

The correct choice for food budget is: Option D. No more than $60 can be spent on food.

The net salary after all deductions will be $66,129 and can be calculated by subtraction of gross salary from all deductions thus option (d) is correct.

To subtract in mathematics is to take something away from a group or a number of objects.

In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

The group's total number of items decreases or becomes lower when we subtract from it.

Gross income = $85,463

Deductions are,

Income will be $896

Exemptions is 2 x $3,650

Charitable donations is $2,145

Exemptions is 2 x $3,650 expenses is $3,473

Add all above the deduction to find out the total deduction,

$896 + $2,145 + $3,473 + 2 x $3,650 = $13,814

Thus, net income will be as by subtraction,

$85,463 - $13,814 = $66,129

Hence "The net salary after all deductions will be $66,129 and can be calculated by subtraction of gross salary from all deductions".
