Can someone pls help me to solve 15 and 16 and answer 17 I will mark you the brainly pls I will really appreciate
Answer:
15) x = 20
16) y = 45°, z = 30°
17) all 4 corners = 90°, all 4 sides are equal length, diagonals are perpendicular, diagonals bisect the corner angles.
We can't do the extra credit because we do not have a relationship about the side lengths. We just have angle information.
Step-by-step explanation:
15) 2x + 8 = 3x - 12
x = 20
16) 2y = 90°
y = 45°
3z = 90°
z = 30°

Linda buys a package of 12 cartons of tomato soup for $30. If each carton holds
16 ounces of soup, what is the cost per quart?
A $1.25
B $2.50
C $5.00
D $7.50
Answer:
5.00
Step-by-step explanation:
1 quart is 32 ounces if you add 16+16=32
and 30 divided by 12 = 2.5
if one carton is 16 ounces and you add 2 cartons to make a quart which is 2.5+2.5=5.00

If 44% of the students in a certain collage are female and there are 2640 female students what is the total number of students in the total students
Answer:Total number of students=6000 students
Step-by-step explanation:
Number of female students =2640
Percentage of female students=44%
But
Percentage of female students x Total number of students =Number of female students
Therefore
Total number of students=Number of female students / Percentage of female students
Total number of students=2640/44% =6000 students

Answer:
B. 315 meters
Step-by-step explanation:
The length of the longer side of the lot on drawing = 6.3 cm
Given a scale of 1cm : 50 m
Let the length of the longer side be represented as x.
Therefore, the actual length of the longer side will be calculated as follows:
1:50 = 6.3:x
1/50 = 6.3/x
Cross multiply
x*1 = 50*6.3
x = 315
Actual length of the longer side of the lot = 315 meters
A sound wave is traveling at 6,420m/s and has a frequency of 600Hz. What is the wavelength?
Answer:
10.7 m
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 6,420 m/s
The frequency of the wave, f = 600 Hz
We need to find the wavelength of the wave. We can find it using the below relation as follows :
[tex]v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{6420}{600}\\\\\lambda=10.7\ m[/tex]
So, the wavelength of the sound wave is equal to 10.7 m.
N is between A and X. AN = 2x + 1, NX = 3x, and AX = 21. what is AN?
Answer:
AN = 9
Step-by-step explanation:
so we can imagine this in a line like:
A---------------N---------------X
Step 1 : solve for x
AX=21 (our total)
because we know that AN+NX together makes AX, we put that into an equation
AN + NX = AX
(2x+1) + (3x) = 21
2x + 1 + 3x = 21 <-- subtract 1 from both sides
2x + 3x = 20 <-- add 2x +3x
5x = 20 <-- divide 5 from both sides
x = 4
Step 2 : input x into AN
AN = 2x + 1 <-- input 4 for x
AN = 2(4) + 1 <-- simplify from there
AN = 9

What changes when the parent function [tex]f(x)=x^2[/tex] is stretched by a positive factor?
9514 1404 393
Answer:
vertical stretch: the function value (f) is multiplied by the stretch factorhorizontal stretch: the variable (x) is divided by the stretch factorStep-by-step explanation:
A stretch can be vertical, horizontal, or both.
Multiplying the function value by a factor greater than 1 will stretch the graph vertically.
Dividing the variable value by a factor greater than 1 will stretch the graph horizontally.

The graph is stretched by the factor according to how it is applied.
how many apples would be left?
Hello!
Lets tackle each section separately!
So Robin gives the first group [tex]\frac{1}{8}[/tex] of the apples.
To find how many apples that is in standard form, we divide 40 by 8.
40 ÷ 8 = 5.
So the first group ate 5 apples.
The second group ate 4 apples.
We do not have to calculate anything since it is already in standard form.
The third group ate 20% of the apples.
To find 20% of forty we can multiply 40 by 0.20, since 0.20 is the decimal equivalent of 20%.
40 × 0.20 = 8.
The last group of children ate 8 apples.
Now we add each groups apple intake together.
5 + 4 + 8 = 17.
Finally, we subtract 17 from 40.
40 - 17 = 23.
There were 23 apples left.

Write an inequality and find the minimum number of hours, to the nearest hour, ... additional $100 in tips waiting tables on Saturday He earned at least $160 in all
The inequality for the given situation is 7.55x+100≥160. Therefore, the minimum number of hours x ≥ 8.
Given that, Shnaggy earned $7.55 per hour plus an additional $100 in tips waiting tables on Saturday he earned at least $160 in all.
What is a inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Let the number of hours be x.
Now, 7.55x+100≥160
Subtract 100 on both the sides of inequality, that is
7.55x+100-100≥160-100
⇒ 7.55x≥60
Divide 7.55 on both the sides of inequality, that is
7.55x/7.55 ≥ 60/7.55
⇒ x ≥ 7.94
7.94≈8
The inequality for the given situation is 7.55x+100≥160. Therefore, the minimum number of hours x ≥ 8.
