By applying Pythagorean's theorem, the hypotenuse of this triangle is equal to: D. √32 inches..

Given the following data:

Adjacent side = 4 inches

Opposite side = 4 inches.

In order to calculate the hypotenuse of this triangle, we would apply Pythagorean theorem.

Mathematically, Pythagorean's theorem is given by this formula:

c² = a² + b²

Where:

Substituting the given parameters into the formula, we have;

c² = 4² + 4²

c² = 16 + 16

c² = 32

c = √32 inches.

Answer:

Sophie has to work 18 hours to buy the sneakers.

Step-by-step explanation:

Since Sophie earns $ 12.80 per hour babysitting, and she has to repay a loan to her parents in the amount of $ 100, and after repaying the loan, she wants to have at least enough money to buy herself a pair of sneakers costing $ 130.40, for write an inequality modeling the number of hours, X, Sophie needs to work to have enough money to buy the sneakers, the following mathematical reasoning must be carried out:

12.80X = 100 + 130.40

12.80X = 230.4

X = 230.4 / 12.8

X = 18

So Sophie has to work 18 hours to buy the sneakers.

Answer:

Maria's homework time is now 9 hours 12 minutes.

Step-by-step explanation:

Since Maria decides to increase her homework time by 15%.

Then,

15% of 8 hours = [tex]\frac{15}{100}[/tex] x 8 hours

                        = 0.15 x 8 hours

                        = 1.2 hours

(Note that: 1.2 hours = 1 hour 12 minutes)

15% of 8 hours = 1 hour 12 minutes

her new homework time = 8 hours + 1 hour 12 minutes

                              = 9 hours 12 minutes

Maria's homework time is now 9 hours 12 minutes.

Answer:

(a) At 1.5 seconds, the ball is 15ft high

Step-by-step explanation:

Given

[tex]Fence:= 20ft[/tex]

[tex]h(t) := -16t^2 + 30t + 6[/tex]

Required

Select the true statement

See attachment for options

Option (a): At 1.5 seconds, the ball is 15ft high

This implies that:

[tex]t = 1.5[/tex]

Substitute [tex]t = 1.5[/tex] in [tex]h(t) := -16t^2 + 30t + 6[/tex]

[tex]h(1.5) = -16 * 1.5^2 + 30 * 1.5 + 6[/tex]

[tex]h(1.5) = -16 * 2.25 + 45 + 6[/tex]

[tex]h(1.5) = -36 + 45 + 6[/tex]

[tex]h(1.5) = 15[/tex]

This statement is true.

Because: [tex]h(1.5) = 15[/tex] means that:

At 1.5 seconds, the ball is 15ft high

Other options will not be checked because only one option can be correct

Answer:

2 more people each day.

Step-by-step explanation:

We are given the following relation:

[tex]d = \frac{192}{n}[/tex]

In which d is the number of days that will take to run a marketing campaign with n people.

Alex’s company will take 32 days to run the campaign.

So the number of people in his campaign is given by:

[tex]32 = \frac{192}{n}[/tex]

[tex]32n = 192[/tex]

[tex]n = \frac{192}{32}[/tex]

[tex]n = 6[/tex]

Shay’s company will take 24 days to run the campaign.

So the number of people in her campaign is given by:

[tex]24 = \frac{192}{n}[/tex]

[tex]24n = 192[/tex]

[tex]n = \frac{192}{24}[/tex]

[tex]n = 8[/tex]

Shays company will have to use more people each day than alex’s company. how many more?

8 - 6 = 2

Answer:

Radius = 5.75

Circumference = 36.13

Step-by-step explanation:

Here we have the diameter, and the radius is half of the so 5.75. For the circumference, we can use the formula C=2πr

Answer:

The bolts with diameter less than 5.57 millimeters and with diameter greater than 5.85 millimeters should be rejected.

Step-by-step explanation:

We have been given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviation of 0.08 millimeters.

Let us find the sample score that corresponds to z-score of bottom 4%.

From normal distribution table we got z-score corresponding to bottom 4% is -1.75 and z-score corresponding to top 4% or data above 96% is 1.75.

Upon substituting these values in z-score formula we will get our sample scores (x) as:

Therefore, the bolts with diameters less than 5.57 millimeters should be rejected.

Now let us find sample score corresponding to z-score of 1.75 as upper limit.

Therefore, the bolts with diameters greater than 5.85 millimeters should be rejected

Answer:

6.30 millimeters and 6.50 millimeters.

Answer: Loss, 200 Rs

Step-by-step explanation:

Given

Sharad bought  a quintal of onion i.e. [tex]1000\ kg[/tex] for [tex]Rs.\ 2000[/tex]

So, the cost price of onion is

[tex]\Rightarrow \dfrac{2000}{100}=20\ \text{Rs per kg}[/tex]

He sells it at [tex]18\ \text{Rs. per kg}[/tex]

Here, the Selling price is less than the cost price

So, he incurs a loss of [tex]2\ \text{Rs per kg}[/tex]

For a quintal it is

[tex]\Rightarrow 2\times 100=200\ \text{Rs}[/tex]

[tex]\Rightarrow \text{Loss }\ \%=\dfrac{C.P.-S.P.}{C.P.}\times 100\\\\\Rightarrow \text{Loss }\ \%=\dfrac{20-18}{20}\times 100=10\%[/tex]

Answer: 49

Step-by-step explanation:

The missing constant term in the perfect square is 49.

x^2 + 14x + 49

We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square.

Answer:

either $180 or $90?

Step-by-step explanation:

first i think you divide 90 by 2, which gives you 45. multiply 45 by 3, which is 135, then multiply 45 by 1, which is just 45. add those together and you get 180. i'm not too sure what you're looking for in the question, but if you're looking for the difference between what he bought them for, it'd be $90. if youre looking for how much he got from those apples, it's $180. hope that helps :)

The amount of pizza left will be 6 / 35.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that John and his dad decide to order a pizza to eat while they are watching a World Cup Soccer game. John eats 2/5 of the pizza, and his dad eats 3/7 of the pizza.

The amount of pizza left will be calculated as below:-

Pizza left = 1 - ( 2/5) - (3/7)

Pizza left = ( 35 - 14 - 15 ) / 35

Pizza left = 6 / 35

Therefore, the amount of pizza left will be 6 / 35.
