Answer:
Lauren's triangle is an isosceles triangle
Step-by-step explanation:
Given the sides of a triangle as 7mm, 9mm and 7mm.
From the given sees you will see that two of the sides are the same showing that the triangle is an isosceles triangle.
An isosceles triangle is a triangle that as two of its sides equal and since two of the sides are both 7mm, hence Lauren's triangle is an ISOSCELES TRIANGLE

Which sum or difference is modeled by the algebra tiles?
A. (x2 - 2x + 3) - (-x - 4x - 2) = 2x - 1
B. (x - 2x - 3) + (x2 - 4x + 2) = 2x - 1
C. (x2 - 2x-3) - (x + 4x + 2) = 2x - 1
D.(X2-2x-3) + (-x2 +4x+2)=2x-1
The sum or difference modeled by the algebra tiles shown in the image is: [tex](x^2 - 2x - 3) - (x + 4x + 2) = 2x - 1[/tex]. The correct option is C.
What is algebra?Algebra is a branch of mathematics that deals with symbols and the rules for manipulating those symbols.
The tiles on the left side of the equation represent the polynomial x^2 - 2x - 3, which can be factored as (x - 3)(x + 1).
The tiles on the right side of the equation represent the polynomial -x - 4x - 2, which can be simplified as -5x - 2.
Substituting these expressions into the original equation, we get:
(x - 3)(x + 1) - (-5x - 2) = 2x - 1
Expanding the left side and simplifying, we get:
[tex]x^2 - 2x - 3 + 5x + 2 = 2x - 1[/tex]
Simplifying further, we get:
[tex]x^2 + 3x - 2 = 2x - 1\\x^2 + x - 1 = 0[/tex]
This is a quadratic equation that can be factored as (x + 1)(x - 1) = 0, which has roots x = -1 and x = 1.
Therefore, the sum or difference modeled by the algebra tiles is C. [tex](x^2 - 2x - 3) - (x + 4x + 2) = 2x - 1.[/tex]

Can of soup has a radius of 3.4 centimeters. Can is 10.2 centimeters tall, what is the approximate area of the label that wrap around the can?
Answer:
218 cm²
Step-by-step explanation:
Can of soup has a radius of 3.4 centimeters. Can is 10.2 centimeters tall, what is the approximate area of the label that wraps around the can?
The formula to solve the above question is given as:
The curved or the lateral surface area of the cylinder = 2πrh
Where:
r = 3.4 cm
h = 10.2 cm
The curved or the lateral surface area of the cylinder = 2 × π × 3.4 cm × 10.2 cm
= 217.9 cm²
Therefore, the approximate area of the label that wraps around the can is
218 cm².
Grace earns $7 for each car she washes. She always saves $29 of her weekly earnings. This week, she wants to have at least $58 in spending money. How many cars must she wash? Enter and solve an inequality to represent this situation.
SOMEONE PLEASE HELP!!!!!!!!
In order to figure out how many cars she must wash, first you should figure out how much money total you need. This week, she needs $25 for her weekly earnings + $65 for spending money = $90. Then you divide the total amount of money, $90, by 7. The answer is 12.8, but because you can't wash 12.8 cars, the answer is 13.

For rhombus,
Diagonal of the rhombus, it bisects the angle of the rhombus.
So,
10x - 23 = 3x + 19
x = 37
Now,
∠RUT + ∠UTS = 180
[37 + 37] + ∠UTS = 180
∠UTS = 180 - 74
∠UTS = 106°
Thus, the requried measure of the angle m∠UTS is given as 106°.

. Neve is examining a tree limb. She notices that the smaller branches spiral away from the larger limb. The limb has 1 branch, then another single branch. After that, the branches spiral in the pattern {2, 3, 5, 8, …}. Can you model the tree growth with the Fibonacci sequence? Explain.
Answer:
[tex]a_1=2\\a_n=a_{n-1}+(n-1)\,,n>1[/tex]
Step-by-step explanation:
Given: The smaller branches spiral in the pattern [tex]\{2,3,5,8,...\}[/tex] from a larger limb.
To model: the tree growth with the Fibonacci sequence
Solution:
Take [tex]a_1=2[/tex]
Let [tex]a_n[/tex] denotes the [tex]n^{th}[/tex] term.
[tex]a_2=3=2+1=2+(2-1)=a_1+(2-1)\\a_3=5=3+2=3+(3-1)=a_2+(3-1)\\a_4=8=5+3=5+(4-1)=a_3+(4-1)[/tex]

what's equivalent to y-1=-5(x-4). A,y=-5x-19. B,y=-5x+19 C,y=-5x-21 D,y=-5+21
Answer:
it must be y=-5x+21
Step-by-step explanation:
lets type the equation in front of us and make it simple so we can deal with it
y-1=-5(x-4)
first thing you need to do is to remove those brackets by multiplying whats in the bracket by -5 like this
y-1=-5x+20 -5*x=-5,, -5*-4=20 (note: when you multiply negative with
negative result is positive)
then add each side by 1 so it will be
y=-5x+21
Niles and Bob sailed at the same time for the same length of time. Niles' sailboat traveled 30 miles at a speed of 6 mph, while Bob's motorboat traveled 70 miles at a speed of 14 mph. For how long were Niles and Bob traveling?
Answer: 5 hours
Step-by-step explanation:
As both of them sailed for the same time, take the speed and distance of either of them to find the time they traveled:
Niles' Time = Distance / speed
= 30 / 6
= 5 hours
Bob's time = 70 / 14
= 5 hours
A Speedboat increases in speed uniformly from 20m/s to 30m/s for 12.2 s. What is the acceleration of the speedboat?
Answer:
0.82 m/s^2
Step-by-step explanation:
Given data
initial velocity=20m/s
Final velocity= 30m/s
Time = 12.2s
Applying the formula
a= v-u/t
a= 30-20/12.2
a= 10/12.2
a= 0.819
a=0.82 m/s^2
