Answer:
x = 6
Step-by-step explanation:
Each side of the triangle = x cm
Each side of the square = (x - 1.5) cm
Given that the perimeter of both shapes are equal, thus, set the perimeter of the triangle equal to the perimeter of the square to solve for x.
Perimeter of triangle = 3(x) = 3x cm
Perimeter of square = 4(x - 1.5) = 4x - 6
Therefore:
Perimeter of triangle = perimeter of square
Substitute
3x = 4x - 6
Subtract 4x from each side
3x - 4x = -6
-x = -6
Divide both sides by -1
x = -6/-1
x = 6
A traffic fanatic wants to estimate the maximum number of cars that can safely travel on a particular road at a given speed. He assumes that each car is 17 feet long, travels at speed s, and follows the car in front of it at a safe distance for that speed. He finds that the number N of cars that can pass a given spot per minute is modeled by the function
N(s) 87s/19 + 19 (s/24)2|
At what speed can the greatest number of cars travel safely on that road?

Complete question :
Seven cards are drawn from an ordinary deck. In how mnat ways is it possible to draw (a) only 5s (b)only 8s, 9s, and 10s, (c) no 8s, 9s, and 10s (d) exactly 2 jacks or kings, (e) 5 spades and 2 hearts?
Answer:
0; 792 ; 100396 ; 30408224 ; 18643560 ;
Step-by-step explanation:
Number of cards in a deck = 52
Number of cards to be drawn = 7
Using combination:
nCr = n! ÷ (n-r)!r!
A.)
Number of 5's in a deck = 4
4C7 = 0
(B.)
only 8s, 9s, and 10s,
Number of 8, 9 and 10's = 4 *3 = 12
12C7 = 12! ÷ 5!7! = 792
(C)
no 8s, 9s, and 10s ;
Number of cards to select from = 52 - (3(4)) = 40C7 = 18643560
(D)
exactly 2 jacks or kings,
Number of jack or king in deck = 8 ; other 5 could be any of the rest : (52 - 8) = 44
8C2 * 44C5 = 28 * 1086008 = 30408224
(e) 5 spades and 2 hearts?
Number of spades = 13
Number of hearts = 13
13C5 * 13C2
1287 * 78 = 100396

The ratio 2/8 could represent which of the following?
A) 8 parts that are one fourth each
B) 4 parts that are one-half each
C) 2parts that are one eighth each
D) 2 parts that are one fourth each
Answer:
C) 2parts that are one eight each.
Step-by-step explanation:
The reason I chose C) as the correct answer is becasue I evaluated it with the steps below.
A) - 8 parts that are one fourth each.
This cannot be correct because it would surpase the 2/8ths (would be over).
B) - 4 parts that are one-half each.
This cannot be correct because it would surpass the 2/8ths (would be over).
C) - 2parts that are one eight each.
This can be correct because 2 parts have 1/8th. 1/8 + 1/8 = 2/8.
D) - 2parts that are one fourth each.
This cannot be correct because the denominator is not 8, it is 4 meaning it wouldn't fit into the format the question asked for (which was 2/8).
This makes the correct answer C).
I hope this helps you understand and helps you in your question.

Studies have suggusted that twins, in their early years, tend to have lower IQs and pick up language more slowly than non-twins. The slower intellectual growth may be caused by benign parental neglect. Suppose it is desired to estimate the mean attention time given
to twins per week by their parents. A sample of 26 sets of two-year-old twin boys was taken, and after one week the attention time
received was recorded. The mean was found to be 27.4 hours with a standard deviation of 11,2 hours. Use this information to contruc
a 98% confidence interval for the mean attention time given to all twin boys by their parents, assuming that the population is
approximately normally distributed, Round the endpoints to one decimal place.
Confidence interval:( , )
Answer:
Confidence interval: (21.9, 32.9).
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 26 - 1 = 25
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 25 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 2.485
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.485\frac{11.2}{\sqrt{26}} = 5.5[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 27.4 - 5.5 = 21.9 hours
The upper end of the interval is the sample mean added to M. So it is 27.4 + 5.5 = 32.9 hours
Confidence interval: (21.9, 32.9).
Write the word sentence as an equation. Then solve the equation.
A number k increased by 7 is 34.
An equation that represents this word sentence is
.
The solution is k=
.
Answer:
27
Step-by-step explanation:
Here's the complete question:
Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.
An increase in k simply means that there's an addition. This will be:
k + 7 = 34
k = 34 - 7
k = 27
Therefore, the value of k is 27
Step-by-step explanation:
Answer:
k = 34 - 7
k = 27
Step-by-step explanation:
increased by 7 = 34 which is means,
this number was 27
The solution is Equation: k = 34 - 7
Solution: k = 27

ILL GIVE BRAINLEST, find the value of x.
Answer:
x⁰ = 45⁰
Step-by-step explanation:
As it is given that the 2 sides of a triangle are equal, then it is an isosceles triangle.
Now, by applying the Triangle Sum Property,
x⁰ + 90⁰ + 45⁰ = 180⁰
x⁰ = 180⁰ - 135⁰
x⁰ = 45⁰
Hope it helps :)
Answer:
x = 45 degrees
Step-by-step explanation:
A triangle is always 180 degrees. One angle is already labeled 45 degrees, and we can tell this is a right triangle, so the other angle is 90 degrees. Add 45 + 90 to get 135. Then subtract 135 from 180 to get 45, which is the value of the missing angle.
Find the area of the semicircle. Round your answer to the nearest hundredth. PLSSSSSSS!!!!!!!!!!!
Answer:
1.57 ft²
Step-by-step explanation:
Diameter = 2ft
Radius = 1/2 (diameter) = 1 ft
Area of semicircle = 1/2( πr²)
Area = 1/2 (3.14)(1)²
Area = 1/2(3.14)
Area = 1.57 ft²

The volume of the cylinder in question is 427.26 inches.
The volume of the cylinder is 427.04 inches 2.
soup pot is 8.5 inches tall
radius of 4 inches.
Volume, is defined as the ratio of the mass of object to its density.
Volume of cylinder = 3.14r^2h
Volume of cylinder = 3.14 x 4 x 4 x 8.5
Volume = 427.04 inches 2

Step-by-step explanation:
Hilbert’s hotel has rooms numbered 1, 2, 3, 4, 5, . . . – one room for each positive integer. Guests are sometimes asked to move rooms, but never more than once a day. Guests are never asked to share a room with anyone else, and guests are never turned away. Guests often arrive to Hilbert’s hotel in one of his special buses. Each bus holds passengers numbered 1, 2, 3, 4, 5, . . . – one passenger for each positive integer. 1. Our story opens with Hilbert’s hotel empty. A bus full of guests arrive at Hilbert’s hotel. (a) How can Hilbert assign people to rooms?
Answer:
For every even numbered room an even numbered guest is assigned to it and for every odd numbered room an odd numbered guest is assigned to it
Step-by-step explanation:
Given that the Hotel is empty and every passenger stands for each positive integer and each number of room represents positive numbers as well
Hilbert can assign people to rooms by using a plot of first come first serve
i.e. For every even numbered room an even numbered guest is assigned to it and for every odd numbered room an odd numbered guest is assigned to it
Question 8 of 10 In the polynomial below, what number should replace the question mark to produce a difference of squares? X2 + ? x-25 А. 0 B. 25 C. 10 D. 5 SUBNET
Answer:
A) The number should be 0
Step-by-step explanation:
The differences of squares formula is x²-a²=(x+a)(x-a)
If we expand (x+a)(x-a), we see that it's x²-ax+ax-a² where -ax+ax=0 since the coefficients cancel out. Therefore, option A is correct.
