Answer:
21 quizzes
Step-by-step explanation:
3 quizzes per week 9÷3=3
7 weeks = 3×7 so 21 quizzes
Answer:
21 quizzes
Step-by-step explanation:
What we know:
- Hayley takes 9 quizzes in 3 weeks
What we want to find:
- The number of quizzes Hayley would've taken after 7 weeks
We need to first find the number of quizzes Hayley would take in 1 week and then multiply that number by 7. To find the number of quizzes per week, divide 9 by 3:
9÷3=3
Therefore, every week, Hayley takes 3 quizzes.
Now, we multiply 3 by 7:
3×7=21
Therefore, after attending 7 weeks of school, Hayley would've taken 21 quizzes in total.
I hope this helps!
find the product of (2y - 1) and (4y² + 2y + 1).
help.
Answer:
8y^3 - 1
I have made it in above picture
Answer:
8y³ - 1Step-by-step explanation:
(2y - 1) × (4y² + 2y + 1) =
= 2y×4y² - 1×4y² + 2y×2y - 1×2y + 2y×1 - 1×1 =
= 8y³ - 4y² + 4y² - 2y + 2y - 1 =
= 8y³ - 1

A regular heptagon has a side of approximately 6.0 yd and an apothem of approximately 6.2 yd.
Find the area of the heptagon.
Answer:
130.2 yd²
Step-by-step explanation:
Area of polygon using the length of the side, s, the apothem, a, and the number of sides, n.
A = san/2
A = (6.0 yd)(6.2 yd)(7)/2
A = 130.2 yd²

area of a circle with a diameter of 4cm
Answer:
A≈12.57cm²
Step-by-step explanation:
A=1
4πd2=1
4·π·42≈12.56637cm²
Answer:
area of a circle with a diameter of 4cm=π(d/2)²
=π(4/2)²=π2²=4π cm ² is your answer or 4×3.16=12.48 cm²

Solve for x by factoring: x^2-30x+200=0
Answer:
x=20,10
Step-by-step explanation:
La un supermarket sau vandut intro zi 32kg de banane si 86kg de portocale incasanduse 536 lei a doua zi sau vandut 96 kg de banane si 52kg de portocale incasanduse 784 lei cati lei costa un kg de banane dar de portocala
Answer:
the banana cost per kg is 6 and for orange it is 4
Step-by-step explanation:
The computation is shown below:
Let us assume the banana be x
And, the oranges be y
Now according to the question
There would be two equations
32x + 86y = 536.......(1)
96x + 52y = 784.........(2)
Now multiply by 3 in equation 1
96x + 258y = 1,608
96x + 52y = 784
258y - 52y = 1608 - 784
206y = 824
y = 4
And, the x would be
32x + 86(4) = 536
32x + 344 = 536
x = 6
Hence, the banana cost per kg is 6 and for orange it is 4
I don't understand this
Answer:
[tex]m = 3 \sqrt{12} [/tex]
[tex]n = 6[/tex]
Step-by-step explanation:
n=1/2 of 12 according to the rule:
right triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
so n=12/2=6
and now we will need Pythagorean theorem : the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
so
[tex] {m}^{2} + {n}^{2} = {12}^{2} [/tex]
now lets put numbers on formula
[tex] {m}^{2} + {6}^{2} = {12}^{2} [/tex]
from this formula m=
[tex]m = \sqrt{ {12}^{2} - {6}^{2} } = \sqrt{144 - 36} = \sqrt{108} = 3 \sqrt{12} [/tex]
Can somebody help me with this please
Answer:
Y = 2x + 4
Step-by-step explanation:
As the question said the slope is 2, so you put 2 with x.
The point you are given is (1,6), so you backtrack to X = 0, and since the slope is 2 you subtract 2 from 6. now you're at (0,4), giving you 4.
KE= 0.5 .m.v2 OR PE= m.g.h Kinetic and Potential Energy Practice Problems. Solve the following problems and show your work! 1. A car has a mass of 2,000 kg and is traveling at 28 meters per second. What is the car's kinetic energy? I
Answer:
784000J or 784KJ
Step-by-step explanation:
Kinetic energy (KE) can be represented with the formula
KE = 1/2(MV²)
where
M = Mass of object (Kg) =2000kg
V = velocity or speed of object in metre per second (m/s or ms^-1) = 28m/s
therefore
KE = 1/2(mv²) becomes
KE = (1/2) X 2000 X 28 X 28
KE = 784000Joules

a certain shade of blue is made by mixing 1.5 quarts of blue paint with 5 quarts of white paint. If you need a total of 16.25 gallons of this shade of blue paint, how much of each color should you mix
Answer:
3.75 of blue mixed with 12.5 of white is the correct answer
Step-by-step explanation:
We know the blue and white paints are a 1.5 : 5 ratio, and if we have a total of 16.25 by 1.5 by 5.
1.5 * 2.5 = 3.75
------------------------
5 * 2.5 = 12.5
SO blue is 3.75 and white is 12.5
Answer:
blue is 3.75 and white is 12.5

Find the value of x. in the below given diagram.
Answer:5,8
Step-by-step explanation:
x^2= 3^2 + 5^2
x^2= 9 + 25
x^2= 34
x = (square root)34
x= 5,8
Answer:
x = [tex]\sqrt{34}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 5² + 3² = 25 + 9 = 34 ( take the square root of both sides )
x = [tex]\sqrt{34}[/tex] ← exact value
x ≈ 5.83 ( to 2 dec. places )
solve for angle x and the length of line segments AO and BO
Answer:
Angle X is 140°.
All four angles = 360, so 90+90+40=220 and 360-220=140
(Still finding length)
