Kindly find number line in attacked picture
Step-by-step explanation:
Price of cupcake per dozen = $15
Projected amount of sales > $120
In other to make such amount in sale, we need to obtain the number of dozens of cupcake :
Project amount of sales / price per dozen
> $120 / $15
> 8 dozens

Multiply the bottom equation by 3 then subtract the bottom equation from the top equation
Multiply the bottom equation by -3/2 then add the equations.
Multiply the top equation by-3. then add the equations
Answers
Answer:
Multiply the bottom equation by -3/2 then add the equations.
Multiply the top equation by-3. then add the equations
Step-by-step explanation:
Given the simultaneous equation
2x- 6y=6 ... 1
6x - 4y = 2 ... 2
To eliminate a variable, we have to make the coefficient of one of the variable to be the same.
Multiply equastion 1 by -3
-6x+18y= -18
6x - 4y = 2
Add the result:
-6x + 6x + 18y-4y = -18+2
18y-4y = -18+2
14y = -18
y = -9/7
Another way is to Multiply the bottom equation by -3/2 then add the equations.
Multiplying equation 2 by -3/2 will give;
6x(-3/2) - 4y(-3/2) = 2(-3/2)
-9x + 6y = -3
Add to equation 1;
2x- 6y=6
-9x + 2x + 0 = -3+6
-7x = 3
x = -3/7
Hence the correct two options are;
Multiply the bottom equation by -3/2 then add the equations.
Multiply the top equation by-3. then add the equations
Malcolm is feeling bags with rice he starts with a 5 1/4 pound container of rice and shells each bag with 5/8 pound of rice how many bags of rice can Malcolm fill
Answers
Answer:
8 2/5 bags of rice
Step-by-step explanation:
The above question is solved as;
5/8 pounds of rice = 1 bag of rice
5 1/4 pounds of rice = x bags of rice
Cross Multiply
5/8 pounds × x bags of rice = 5 1/4 pounds of rice × 1 bag of rice
x bags of rice = 5 1/4 pounds of rice × 1 bag of rice/ 5/8 pounds
x bags of rice = 5 1/4 ÷ 5/8
x bags of rice = 21/4 ÷ 5/8
x bags of rice = 21/4 × 8/5
x bags of rice = 42/5
x bags of rice = 8 2/5 bags of rice
Therefore, malcolm can fill 8 2/5 bags of rice.

Step-by-step explanation:
The measure of the external angle where the secants meet is half the difference of the arcs they subtend.
∠A = (DE - BC)/2
2×∠A = DE -BC
DE = BC + 2×∠A
DE = 38° +2(12°)

Step-by-step explanation:
First we will divide those who attended with the estimated number 0f those who should attend.
= 817/825
= 0.9903
We will then multiply the above result with 100
= 100 × 0.9903
= 99.0303
The next step is to deduct the above result from 100
= 100 - 99.0303

Cost of cashews cost $2 more than peanuts. Gabriel orders 4 cans of cashews and 3 cans of peanuts the total cost was $56. Write an equation for the cost of peanuts
Answers
Answer:
3x = 56 - (4x + 8)
Step-by-step explanation:
Let
Cost of peanut = x
Cost of Cashew = x + 2
Total Cost = Cost of Cashew + Cost of peanut
56 = (x+2) * 4 + x * 3
Cost of peanut: 3x = 56 - (4x + 8)
Total Cost = Cost of Cashew + Cost of peanut
56 = (x+2) * 4 + x * 3
56 = (4x + 8) + 3x
56 = 4x + 8 + 3x
56 = 7x + 8
56 - 8 = 7x
48 = 7x
x = 48/7
x = 6.86

The angle of depression from a helicopter to its landing space is 56°. If the helicopter is flying at 1000 ft, find the distance from the helicopter to the landing space
Answers
Answer:
[tex]1206.22\ \text{ft}[/tex]
Step-by-step explanation:
The height at which the helicopter is 1000 ft
Angle of depression is [tex]56^{\circ}[/tex]
[tex]\theta=90-56=34^{\circ}[/tex]
We have the relation
[tex]\cos\theta=\dfrac{\text{Adjacent side}}{\text{Hypotenuse}}\\\Rightarrow \cos34^{\circ}=\dfrac{1000}{x}\\\Rightarrow x=\dfrac{1000}{\cos 34^{\circ}}\\\Rightarrow x=1206.22\ \text{ft}[/tex]
The distance of the helicopter to the landing space is [tex]1206.22\ \text{ft}[/tex].
