Answer:
CB=18
And the measure of angle BDA is 21 degrees
Step-by-step explanation:
Answer: ∠BDA = 21; CB = 30
have:
sin ∠BDC = [tex]\frac{4x+6}{BD}[/tex]
sin ∠ADB = [tex]\frac{7x-12}{BD}[/tex]
because ∠BDC = ∠ADB => sin ∠BDC = sin ∠ADB
=> [tex]\frac{4x+6}{BD}=\frac{7x-12}{BD}[/tex]
=> 4x + 6 = 7x -12
<=> 3x = 18
<=> x = 6 => CB = 4.6 + 6 = 30

A factory makes Jars in batches of 160 and lids in batches of 216. The next puts the jars in a row, fills them and then attaches the lid. They want to make the largest row possible so the jars and lids are divided evenly by the rows. What is the largest row possible?
Answer:
8 is the largest row possible
Step-by-step explanation:
What this question is simply asking is to find the greatest common factor of 216 and 160
The greatest common factor of 216 and 160 is 8
So what this mean is that the largest row possible is 8

Chandler wants to raise 200$ to buy a new gaming system. He already has 80$ and plans to save 40$ a week. How many weeks will it take chandler to raise enough money to buy his gaming system?
Answer:
3 weeksStep-by-step explanation:
Step one:
given data
expected amount =$200
cash already at hand=$80
savings per week=$40
let the number of weeks be x
Step two:
the linear function for the situation is the same as the equation of a straight line
y=mx+c------1
200=4x+80
solve for x
200-80=40x
120=40x
divide both sides by 4
x=120/40
x= 3 weeks
Chandler will save for 3 weeks
here is a list of ingredients for making 12 rock cakes nihay wants to make 42 cakes does she have enough sugar to make 42rock cakes u must show your working
Step-by-step explanation:
So we know that for 12 rock cakes we need 225g flour and 75g sugar to get 42 rock cakes we need to multiply the number of ingredients by 3.5 (42/12 =3.5)
This gets us 787.5 g flour and 262.5 g sugar.
Show work:
[tex]42 \div 12 = 3.5[/tex]
[tex]225 \times 3.5 = 787.5[/tex]
[tex]75 \times 3.5 = 262.5 [/tex]
[tex]787.5 < 800[/tex]
[tex]262.5 < 300[/tex]
Nishat has enough flour and sugar to make 42 rock cakes.

Aubrey wants to save money to purchase a new bicycle that costs $275. If she saves $5 per week, how many weeks will it take Aubrey to have enough money to purchase the bicycle?
55 semanas, porque si tomas los $275 y los dividís en $5 te da 55,lo que serian las semanas
soy de Argentina,salu2 C':
Answer:
55
Step-by-step explanation:
Set up an equation first like this,
5x=275
you would set it up like this because she needs $275 and she saves her money for a _____ amount of weeks that's why I said x, we want to know the number of weeks. So you would divide 275 by 5 and you get 55. So she will need to save up for 55 weeks.
Sarah works ar a shoe store. She earns a base salary of $1,500 per month, plus a 25% commission on the amount of shoe sales she makes druing the month. If Sarah's goal is to earn $2,000 a month, what is the amount of shoe sales that she must make in a month?
Answer:
Step-by-step explanation:
goal is 2,000 and she already makes 1,500
2,000-1,500 gives you the amount she needs to earn from shoe sales
she needs to earn 500 dollars with a 25% commision
25% can also be written as 25/100
for every $100 she makes, she gets $25 but she needs $500
100:25
we need the second number in the ratio to equal $500
500 divided by 25 is 20
20 x 100 : 25 x 20
2000: 500
ANOTHER WAY: 500 is 1/4 of 2000 and 1/4 is 25% so you could multiply the amount she needed by 4 to get your answer
Which equation is equivalent to 4 - 6(3 - 2x) = 3(x - 4)?
a. 15x= -2 b. 5x=-10 c. 9x=2 d. 15x=2
Answer:
9x=2
Step-by-step explanation:
4 - 6(3 - 2x) = 3(x -4)
4 - 18 + 12x = 3x - 12
12x - 14 = 3x - 12
12x - 3x = 14 - 12
9x = 2

What is the volume of the square pyramid? Round to the nearest hundredth, if needed.
5 in.
9 in.
9 in
0405 in 3
135 in. 3
675 in 3
75 in. 3
Answer:
The answer is 135 in 3.
Step-by-step explanation:
To find the volume of a square pyramid, first you need to find the base and height. In this case,
a = 9
h = 5
Now we use the formula (1/3 a^2 h) To find the volume.
I will use )( To show numbers being multiplied, example: 3)(4 = 12
=1/3)(9 cm^2)(5 cm
=1/3)(81 cm)( 5 cm
= 135 in. 3

Answer:
A. 127º
Step-by-step explanation:
So we already know that the inside of a triangle is equal to 180º. We already have two of the angles so we can start by adding those together.
75 + 52 = 127
180 - 127 = 53
m∠A = 53º
Now, we also know that a straight line is equal to 180º so all we have to do now is subtract 53 from 180 to get the measure of ∠BAD
180 - 53 = 127

How to find vertex form with vertex: (3,6) and y intercept: 2
Answer:
f(x) = - ⁴/₉(x - 3)² + 6Step-by-step explanation:
The vertex form of the equation of the parabola with vertex (h, k) is:
f(x) = a(x - h)² + k
So for vertex (3, 6) it will be:
f(x) = a(x - 3)² + 6
y intercept: 2 means f(0) = 2
f(0) = a(0 - 3)² + 6
2 = a(-3)² + 6
2 -6 = 9a + 6 -6
-4 = 9a
a = ⁻⁴/₉
Therefore:
The vertex form of quardatic function with vertex: (3,6) and y intercept: 2 is
f(x) = - ⁴/₉(x - 3)² + 6
The vertex form of the parabola equation is f(x) = -4/9(x - 3)² + 6 if the vertex: (3,6) and y intercept: 2
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
(x - h)² = 4a(y - k)
(h, k) is the vertex of the parabola:
a = √[(c-h)² + (d-k²]
(c, d) is the focus of the parabola:
It is given that:
The vertex: (3,6) and y-intercept: 2
As we know,
The parabola equation:
f(x) = a(x - h)² + k
Here (h, k) is the vertex of the parabola and a is the leading coefficient.
f(x) = a(x - 3)² + 6
f(x) = 2 at x = 0
2 = a(0 - 3)² + 6
a = -4/9
f(x) = -4/9(x - 3)² + 6
Thus, the vertex form of the parabola equation is f(x) = -4/9(x - 3)² + 6 if the vertex: (3,6) and y intercept: 2
