A box contains 3 pens, 2 markers, and 1 highlighter. Tara selects one item at random and does not return it to the box. She then selects a second item at random. What is the probability that Tara selects 1 pen and then 1 marker?
Answer:
1/5
Step-by-step explanation:
There are a total of 6 items in the beginning. In the first selection, there is a 3/6 chance that she selects a pen. Since she does not return it to the box, there are 5 items left. The possibility to select a marker is 2/5. Simply multiply the two fractions. You will get 1/5.

Answer:
30cm
Step-by-step explanation:
The perimeter of the triangle is the sum of all of its sides
Since the triangle is an isosceles triangle, then AC = BC
Since AC = 3cm + 9cm = 12cm, then;
AC = BC = 12cm
For AB;
AB = 3cm + 3cm
AB = 6cm
Perimeter of the polygon = AC+BC + AB
Perimeter of the polygon = 12cm + 12cm + 6cm
Perimeter of the polygon =30cm
which expression is equal to 24x^2-22x+5
Answer: (12x−5)(2x−1)
Step-by-step explanation: Hope this help :D
Answer:
24(x^2)-22x+5
=24(x^2)-(12+10)x+5
=24(x^2)-12x-10x+5
=12x(2x-1)-5(2x-1)
=(2x-1)(12x-5)

Given:
The recipe calls for [tex]\dfrac{3}{8}[/tex] cup of chili powder.
Karl only wants to use half as much so it won’t be so spicy.
To find:
How much chili powder should Karl use?
Solution:
We have,
Chill power for recipe = [tex]\dfrac{3}{8}[/tex] cup
Chill power used by Karl is half of chill power for recipe.
[tex]\text{Chill power used by Karl}=\dfrac{1}{2}\times \dfrac{3}{8}[/tex] cup[tex]\text{Chill power used by Karl}=\dfrac{3}{16}[/tex] cup
Therefore, [tex]\dfrac{3}{16}[/tex] cup of chili powder should Karl use.

The first laptop ever was sold was the Osborne 1. It came onto the market in 1981, and it had a mass of 11 kg. Suppose that since 1981 the mass of laptops has decreased at an average rate of 4.7% per year. What was the approximate weight of a laptop in 2019?
a. 6.43 kg
b. 8.10 kg
c. 4.62 kg
d. 1.76 kg
Answer: (d)- 1.76 kg
Step-by-step explanation:
Given
The first laptop mass was 11 kg
The rate of mass decreases by 4.7% per year
In 1982, it was
[tex]\Rightarrow 11-11\times 4.7\%=11-11\times 0.047\\\Rightarrow 11(1-0.047)\ kg[/tex]
In 1983, it was
[tex]\Rightarrow 11(1-0.047)-11(1-0.047)\times 0.047=11(1-0.047)^2[/tex]
In 2019 i.e. after 38 years, it is
[tex]\Rightarrow 11(1-0.047)^38=11\times 0.953^{38}=1.76\ kg[/tex]

if y varies inversely as x, and y =35 when x =14, find x when y =15.
Answer:
[tex]x = 32 \frac{2}{3} [/tex]
Step-by-step explanation:
[tex]y = \frac{k}{x} ,where \: k \: is \: a \: constant.[/tex]
Let's find the value of k first.
When y= 35, x= 14,
[tex]35 = \frac{k}{14} [/tex]
k= 14(35)
k= 490
Substitute the value of k into the equation:
[tex]y = \frac{490}{x} [/tex]
When y= 15,
[tex]15 = \frac{490}{x} [/tex]
15x= 490
x= 490 ÷15
[tex]x = 32 \frac{2}{3} [/tex]

15. Ethan planted sunflowers in different types of soil and measured their growth each week.
Plant 1 started at a height of 10 inches and grew 10 inches per week. Plant 2 started at a
height of 18 inches and grew 8 inches per week. Ethan wants to predict the number of weeks
it will take for the plants to reach the same height.
Ethan concludes that the plants will reach the same height after 50 weeks. Is Ethan correct?
Explain why or why not.
Answer:
He is not correct
Step-by-step explanation:
10 x 50 = 500
500 + 10 = 510
510 represents plant 1 height after 50 weeks
8 x 50 = 400
400 + 18 = 418
418 represents plant 2 after 50 weeks
they're not the same height
Answer: No he is not correct
Step-by-step explanation:
plant 1 will be taller than plant 2 at 50 weeks
do 50 times 10 = 500in
do 50 times 8 = 400in

The sides of a right triangle are used to construct three squares, as shown below. The number of square units, representing area, is shown in two of the squares. A represents the area of the largest square.
1. We know that the distance formula will be be d=√((x_2-x_1)²+(y_2-y_1)²), then we can do x2-x1=3. Y2-Y1=5. 3x3+5x5=34, the square root of 34 is around 5.83. The answer is F.

What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the area of the square A be = S
Let the triangle be represented as ΔABC
The base of the triangle BC = 5 units
The height of the triangle AB = 3 units
So , the hypotenuse of the triangle AC = Side of the square A
And , from the Pythagoras theorem
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Substituting the values in the equation , we get
AC² = AB² + BC²
AC² = 5² + 3²
AC² = 25 + 9
AC² = 34 units²
AC² = Area of the square A with side AC
Therefore , the value of S is 34 units²
Hence , The area of the square with the side having the hypotenuse of the triangle as the side is 34 units²
