An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7.
Which lengths make sense for possible values of b? Check all that apply.
–2 in.
0 in.
0.5 in.
2 in.
7.9 in.
Answer:
0.5 in, 2 in
Step-by-step explanation:
It cannot be a negative number, so -2 is out.If we use Pythagorean's theorem ([tex]a^2+b^2=c^2[/tex]), we know that only 0.5 and 2 are correct values of b.Identify the end behavior brain list for whoever gets it right
Answer:
Number 4, the last one
Step-by-step explanation:
The answer is the first choice.
For every odd-degree polynomial function,
When x approaches positive infinity, y approaches positive infinity.
When x approaches negative infinity, y approaches negative infinity.
As shown in the graph, substituting x into any numbers that are greater than 3 and you'll see how the graph heads toward y-value infinitely.

The perimeter of a rectangle is 52 feet. The length is 2 more than twice the width. What is the length of the rectangle?
Answer: The Length of the rectangle is 18 feet.
The width is 8 feet
Step-by-step explanation: Perimeter is 2w + 2L
Length here is 2w + 2 Substitute this value for L in the equation.
P = 2w + 2L
52 = 2w + 2(2w + 2) distribute and add
52 = 2w + 4w + 4
52 = 6w + 4 Subtract 4 from both sides, Then divide both sides by 6 to solve for w
48 = 6w
8 = w The width is 8 ft
Substitute into the original expression for Length
Length here is 2w + 2 : 2(8) + 2 16 + 2 = 18
The Length is 18 feet.
Check: in the original equation P = 2w + 2L
52 = 2(8) + 2(18)
52 = 16 + 36 TRUE!
Answer:
The length would be 18ft the width would be 8ft

Convert the equations form standard form to slope intercept form 8x-10y=20
Answer:
y=4/5x-2
Step-by-step explanation:
8x-10y=20
-10y=-8x+20 subtract 8x from both sides
x=4/5x-2 divide everything by -10

A tv has a screen that is 15 in long and has a 25 in long diagonal find the area of the tv screen?
Answer:
300 in²
Step-by-step explanation:
The TV screen is rectangular in shape.
Thus:
Length of the rectangular screen = 15 in.
Diagonal of the rectangular screen = 25 in.
To find the area of the rectangular screen, we need the length and the width of the screen.
Use pythagorean theorem to find the width as shown below:
[tex] a^2 + b^2 = c^2 [/tex], where:
a = width = ?
b = 15 in.
c = 25 in. (The hypotenuse/longest side)
Plug in the values into the equation
[tex] a^2 + 225 = 625 [/tex]
Subtract 225 from each side
[tex] a^2 = 400 [/tex]
Take the square root of both sides
[tex] a = 20 [/tex]
width of the screen = 20 in.
Thus,
Area of the screen = length × width
= 15 × 20
Area = 300 in²

A school is taking a group of students on a field trip to the aquarium. Including chaperones, 132 people will be going on the field trip. Found out it's 110 students. The ratio of shark bookmarks to seal bookmarks to the students is 3:2. How many students receive shark bookmarks?
Given:
Total people = 132
Total students = 110
The ratio of shark bookmarks to seal bookmarks to the students is 3:2.
To find:
The number of students who receive shark bookmarks.
Solution:
Let the total number of students who receive shark bookmarks be 3x and number of students who receive seal bookmarks be 2x.
Total number of students is 110. So,
[tex]3x+2x=110[/tex]
[tex]5x=110[/tex]
Divide both sides by 5.
[tex]x=22[/tex]
Now,
Number of students who receive shark bookmarks [tex]=3x[/tex]
[tex]=3(22)[/tex]
[tex]=66[/tex]
Therefore, 66 students receive shark bookmarks.

Andrew ate 2/3 of the desert. cassandra ate 5/16 of the desert. what portion of the desert did andrew and cassandra eat altogether?
Answer:
Concept: Fractions
A ate 2/3 and C ate 5/16Let us find a common denominator Let 48 be our common DHence 32/48+ 15/48 = 47/48Answer:
The portions added together make 47/48 of the dessert.
Step-by-step explanation:
To find the total amount that Andrew and Cassandra ate of the dessert, we have to add the two fractions together:
[tex]\frac{2}{3} + \frac{5}{16}[/tex]
[tex]\frac{32}{48} + \frac{15}{48}[/tex]
[tex]\frac{47}{48}[/tex]
Hence, Andrew and Cassandra almost ate up all of the dessert, clocking in at 47/48 of the dessert.
Hope this helped!

Increase 60kg by 33⅓ please help!
Answer:
2000 kg is the answer.
Step-by-step explanation:
We need to increase 60 kg by [tex]33\dfrac{1}{3}[/tex].
The given value is 60 kg. We can find it by finding [tex]33\dfrac{1}{3}[/tex] of 60 kg.
[tex]=60\times \dfrac{100}{3}\\\\=20\times 100\\\\=2000[/tex]
Hence, if we increase 60 kg by [tex]33\dfrac{1}{3}[/tex], we will get 2000 kg.
