Can someone plz help me with the first one also it will be appreciated if u could show working out too!
Answer:
Angles in a quadrilateral add up to 360°.
[tex]90 + 3x + x + 20 + 2x + 10 = 360\\ 90 + 20 + 10 + 3x + x + 2x = 330\\ 120 + 6x = 360 \\ 6x = 360 - 120 \\ 6x = 240 \\ x = \frac{240}{6} \\ x = 40[/tex]
[tex]3x = 3 \times 40 = 120 \\ [/tex]
[tex]x + 20 = 40 + 20 = 60[/tex]
[tex]2x + 10 = 2 \times 40 + 10 = 80 + 10 = 90[/tex]
Difference between largest & smallest angles =
[tex]120 - 60 \\ = 60[/tex]
60 is the difference the largest & the smallest angle.

If 9/10 is multiplied by 8/9 , will the product be greater than either of the two factors?
Answer:
No, both of the numbers are less than one whole and when you multiply them (I got 4/5) 4/5 is less than both of the factors.
Answer:
No
Step-by-step explanation:
It will not be because when a number is numtiplied by one, it stays the same. However, both of these are numbers less than 1, so the product will be smaller
1. Alyssa is twice as old as Brittany, and Jazmin is 15 years older than Alyssa. If Jazmin is 45 years old, how old is Brittany?
Write two algebraic equations, let represent Alyssa’s age in years and represent Brittany’s age in years.
Tysm if u do this <3
Answer:
Brittany is 15 years old
Step-by-step explanation:
The way we get the answer is by getting the age of Alyssa 45-15=30 as, Jazmin is 15 years older than Alyssa and then we can see that Alyssa is twice as old as Brittany so we divide Alyssa's age by two. 30÷2=15 and we get Brittany's age which is 15 years old.
The quadratic function f(x) has one zero at x=-5 and a turning point at (3,10). What is the value of its other zero?
The quadratic function [tex]f(x)[/tex] has one zero at [tex]x=-5[/tex] and a turning point at [tex](3,10)[/tex]. The value of other zero is [tex]11[/tex].
What is Quadratic function?The Quadratic function [tex]f(x)[/tex] is a polynomial function with one or more variables in which the highest power of the variable is two. i.e. [tex]f(x) = ax^{2} + bx + c[/tex]
What are zeros?The zeros of a polynomial [tex]f(x)[/tex] are all the [tex]x[/tex]-values that make the polynomial equals to zero. i.e. [tex]f(x)=0[/tex]
What is turning point?A turning point is a point at which the derivative changes sign.
We have,
One zero is [tex](-5)[/tex],
Let other Zero be [tex]"a"[/tex],
Turning point at [tex](3,10)[/tex].
i.e. [tex]x=3[/tex] and [tex]y=10[/tex]
Since the difference between [tex]3[/tex] and [tex](-5)[/tex] is [tex]8[/tex].
So,
The difference between the other zero from [tex]3[/tex] should be the same as the difference between [tex]3[/tex] and [tex](-5)[/tex].
i.e.
[tex]a-3=8[/tex]
[tex]a=11[/tex]
Hence the value of its other zero is [tex]11.[/tex]

Leonard made the 3-d shape below for an art project. He wants to paint it blue.
How many square centimeters of paint does he need to paint the outside of every
side except for the bottom?
10 cm
6 cm
Answer:
90 [tex]cm^{2}[/tex] of blue paint
Step-by-step explanation:
From the given diagram, the sides have the same dimensions and the shape of a triangle.
Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height
Given that, the base of each side = 6 cm, and the height = 10 cm.
Then,
Area of each side of the shape = [tex]\frac{1}{2}[/tex] x 6 x 10
= 30 [tex]cm^{2}[/tex]
Since Leonard wish to paint only the 3 sides and not the bottom part of the shape, the amount of paint required can be determined as;
3 x area of each side = 3 x 30
= 90 [tex]cm^{2}[/tex]
Leonard would need 90 [tex]cm^{2}[/tex] of paint to paint the sides of the shape.

The length of a rectangle is one less than twice its width. The area is 66 square centimeters. Find the length and width.
Answer:
I. Length, L = 11 cm
II. Width, W = 6 cm
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Area of rectangle = 66 cm²
Translating the word problem into an algebraic expression, we have;
L = 2W - 1 .....equation 1
We know that the area of a rectangle is given by the formula;
A = L * W
Substituting
66 = L * W ....equation 2
Substituting eqn 1 into eqn 2, we have;
66 = (2W - 1) * W
66 = 2W² - W
2W² - W - 66 = 0
Note: the standard form of a quadratic equation is ax² + bx + c = 0
a = 2, b = -1 and c = -66
Solving the quadratic equation using the quadratic formula;
The quadratic equation formula is;
[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]
Substituting into the equation, we have;
[tex] x = \frac {-(-1) \; \pm \sqrt {1^{2} - 4*2*(-66)}}{2*2} [/tex]
[tex] x = \frac {1 \pm \sqrt {1 - (-528)}}{4} [/tex]
[tex] x = \frac {1 \pm \sqrt {1 + 528}}{4} [/tex]
[tex] x = \frac {1 \pm \sqrt {529}}{4} [/tex]
[tex] x = \frac {1 \pm 23}{4} [/tex]
[tex] x_{1} = \frac {1 + 23}{4} [/tex]
[tex] x_{1} = \frac {24}{4} [/tex]
x1 = 6
We do not need the negative value of x, so we proceed.
Therefore, Width, W = x1 = 6 cm
Next, we find the length L;
From eqn 1;
L = 2W - 1
L = 2(6) - 1
L = 12 - 1
L = 11 cm

Ben enters the water during a scuba dive. After 41 seconds of diving, his depth changes by - 29 feet. He wants to know his average change in depth each second. Write an expression for the average change in depth each second.
Answer:
-0.7073ft/sec
Step-by-step explanation:
Given the following
Distance covered by Ben = -29feet
Time taken = 41secs
Required
average change in depth each second(speed)
average change in depth each second = Distance/Time
average change in depth each second = -29/41
average change in depth each second = -0.7073ft/sec
Answer:
The answer is -29 divided by 41

Answer:
a) 1000+0.05x ≥2200
b) x=24000
Step-by-step explanation:
a) So we know that Nadia for certain gets paid $1000 each month. That is a concrete amount that doesn't change, so the variable (x) would be placed on the 5% she earns from sales. We don't know how much she sells each month because it varies, so that will be represented by the X. Her goal is to raise NO LESS than $2200, which means the amount she earns from sales has to be greater than or equal to $2200.
b) From here just solve the equation for X:

If you had a sealed bottle of water, how would the mass of
the water bottle change after a 5 day period?
A. mass would increase
B. mass would stay the same
C. mass would decrease
D. none of the above
Using the density concept, it is found that the mass would stay the same, and the correct option is given by B.
-----------------
Density is mass divided by volume, that is:[tex]d = \frac{m}{v}[/tex]
Using the equation, the mass will be given by:[tex]m = dv[/tex]
-----------------
The density of the water is constant, so it would stay the same after 5 days.The bottle will be sealed, thus the amount of water, that is, the volume, will also stay the same.Mass is multiplication of mass and volume, since both stay the same, mass also stays the same, and thus, the correct option is B.A similar problem is given at https://brainly.com/question/16909559
