What does X equal in this 30-60-90 triangle?
Answer:
Well in a 30-60-90 triangle there are 2 rules
The short leg is “x” (for now)
The hypotenuse leg is twice the shorter leg (2x)
And the longer leg is x√3
Now using that information we can tell that the hypotnuse here is 19. It’s flipped over.
We know that x is the shorter leg here. So its half of the hypotnuse (19).
19/2 = 9.5
X= 9.5
Which graph represents a function?
Answer:
the third one (bottom left)
Step-by-step explanation:
all the others have at least one x value with multiple possible y values.
but for a function, there must be exactly 1 y value for each defined x value.
two nimbers have a product of 90 and a sum of 19. What are the two numbers?

Find the area of the rectangle.
The area of the rectangle is the length times the width.
Now let's convert all these fractions into improper fractions to make it easier to multiply
[tex]4\frac{3}{4} =\frac{19}{4} \\1\frac{1}{6} =\frac{7}{6}[/tex]
Now let's multiply them for the area = [tex]\frac{19}{4} *\frac{7}{6} =\frac{133}{24} =5\frac{13}{24}[/tex] square feet.

What type of transformation occurred if the quadratic parent function becomes y = 3x² + 9
Horizontal compression, vertical up
Vertical stretch, vertical up
Horizontal stretch, vertical down
Vertical compression, vertical down
Answer:
Horizontal compression, vertical up
Step-by-step explanation:
The 3 compresses the parent function
The 9 moves it up 9 Spaces
Answer:
Horizontal compression, vertical up . . . or ...Vertical stretch, vertical upStep-by-step explanation:
The transformation to the parent quadratic function can be described either of two ways. For a quadratic, a vertical stretch can also be accomplished by a horizontal compression.
The transformations of interest here are ...
g(x) = a·f(x) . . . . vertical stretch by a factor of 'a'
g(x) = f(a·x) . . . . horizontal compression by a factor of 'a'
g(x) = f(x) +a . . . . vertical translation by 'a' units
__
It is easy to see that the parent function f(x) = x^2 has had 9 added to it, so the function has been translated upward 9 units.
The transformation to 3x^2 can be accomplished either of two ways:
3x^2 = 3(x^2) . . . vertical stretch by a factor of 3
3x^2 = (x√3)^2 . . . . horizontal compression by a factor of √3
The attached graph shows either a horizontal compression or a vertical stretch will result in the same graph.
__
Additional comment
In the interest of using rational scale factors, we prefer the "vertical stretch, vertical up" description.

An angle measures 82º more than the measure of its complementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
Let one angle be x
Other angle =x + 82
Complementary angles add up to 90
x + x + 82 = 90
2x + 82 = 90
2x = 90 - 82
2x = 8
x = 8/2
x = 4
Other angle = x + 82
= 4 +82
= 86
The angles are: 4 , 86
An angle measures 82º more than the measure of its complementary angle. What is the measure of each angle?
❖ Explanation -:Given -:
An angle measures 82º more than the measure of its complementary angle.Need to find -:
Measure of each angleAssuming -:
An angle measures 82º more than the measure of its complementary angle.
Let us assume one angle as x
Then other angle = (x + 82)
Solution -:
First we will make an equation
We know,
Complementary angles add up to 90°
x + (x + 82°) = 90°
→ x + x + 82° = 90°
→ 2x + 82° = 90°
→ 2x = 90° - 82°
→ 2x = 8
→ x = [tex]\cancel{\dfrac{8}{2}}[/tex]
→ x = 4
Substituting the value of x = 4
One angle = x = 4°
Other angle = x + 82° = (4 + 82)° = 86°
Final Answer -:
The angles are 4 and 86.[tex] \rule{180pt}{2pt}[/tex]

60yd²Step-by-step explanation:
1. Find the Surface area of the Triangles
3x4x1/2=
12x1/2=
6
For both of the triangles =
6x2=12
So, the two triangle's surface area is 12 yd²
2. Find the surface area of the Base (rectangle)
4x4=16
So, the surface area of the base is 16yd²
3. Find the surface area of the back rectangle
3x4=12
So, the surface area of the back rectangle is 12yd²
4. Find the surface area of the top rectangle
4x5=20
So, the surface area of the top rectangle is 20yd²\
5. Add up all of the answers for Surface area.
12+16+12+20
12+16=28

Adrianna has $16 worth of quarters and dimes. If Adrianna has 21/2 times as many dimes as she does quarters, how many quarters does she have?
Answer:
32 quaters
Step-by-step explanation:
We have two unknowns, the number of quarters, Q and the number of dimes, D.
Since we have two unknowns, we need to come up with two equations using these unknowns
1st Equation) We know that 1 quarter = 0.25 dollars, 1 dime = 0.10 dollars and that Adriana has 16 dollars:
0.25 *Q + 0.10 * D = 16 dollars
2nd Equation) The problem also states that Adriana has two and half (2.5) times as many dimes than quarters:
D =2.5 * Q
Substitute Equation 2 into Equation 1 and solve for Q, the number of quarters
0.25 * Q + 0.10 * (2.5 * Q) = 16.00
(0.25 + 0.25) Q = 16
0.5 * Q = 16
Q = 16 / 0.5 = 32
Adriana has 32 quarters.
Adriana also she 2.5 * 32 dimes, which means she has 80 dimes
Check the results
0.25 * 32 + 0.10 *80 = 16.00
8.00 + 8.00 = 16.00
16.00 = 16.00

Ayudaaa help
Answer:
103 inches
Step-by-step explanation:
So, Since we know that 12 in = 1 foot
all we have to do is multiply 12 by 8. Think of it like: what will 8 sets of 12 blocks give us?
8 x 12 = 96
So, 8 feet is 96 inches.
Now, Just add the 7 inches into the 96 inches.
96+7 = 103 inches
and then you are done!

In a certain chemical, the ratio of zinc to copper is 3 to 19. A jar of the chemical contains 494 grams of copper. How many grams of zinc does it contain?
enter your response here
It contains grams of zinc.
Answer:
3216 grams of Zn
Step-by-step explanation:
It is not clear from the question if the ratio is based on the chemical formula, and is thus the ratio of atoms, or if it is based on mass (in g). I'll assume it is based on the numbers of Zn and Cu atoms.
Let's convert the mass of copper, 494 grams, to moles of copper (representative of the number of atoms). The molar mass of copper, Cu, is 63.55 grams/mole.
Moles Cu =(494 grams)/(63.55 grams/mole) = 7.77 moles Cu
If zinc (Zn) is in a ratio of 19/3, we would have:
(19 moles Zn/3 moles Cu)*(7.77 moles Cu) = 49.2 moles of Zn
The molar mass of zinc is 65.38 grams/mole
The mass of 49.2 moles of Zn is:
(49.2 moles Zn)(65.38 grams/mole) = 3216 grams of Zn

In Chicago, there is a 30% chance that Memorial Day will have a high temperature in
the 70s. What is the probability that next Memorial Day will not have a high
temperature in the 70s in Chicago?
Answer:

Javier and his two friends are going to the basketball game. Each student pays $2 for their ticket and buys 3 snacks (all snacks cost the same). If all together, they spend $17.25, how much does each snack cost?
Answer:
Each snack cost $3.75.
Step-by-step explanation:
Javier and his two friends paid 6 bucks for their tickets in total.
If all together they spent 17.25 at the game, we can deduct 6 dollars from 17.25 so we can just get the snack total.
17.25-6=11.25
Since there are three people, and they bought 3 snacks, we can divide:
11.25/3=3.75
Each snack cost $3.75
Answer:
3.75 is z answer hope dis helped
