Answer : The amount of margarine needed is 1 kg.
Step-by-step explanation :
First we have to convert volume of syrup from mL to L.
Conversion used:
1 L = 1000 mL
or, 1 mL = 0.001 L
So, 225 mL = 0.225 L
Now we have to calculate the amount of margarine needed.
As, 0.225 L of syrup needed 150 g of margarine
So, 1.8 L of syrup needed  of margarine
 of margarine
Amount of margarine needed = 1000 g = 1 kg     (1 kg = 1000 g)
Therefore, the amount of margarine needed is 1 kg.
 
        
             
        
        
        
Answer: FALSE.
Step-by-step explanation:
 Given the following equation provided in the exercise:
 
 You need to solve for the variable "x". 
 In order to solve for "x" you can folllow the steps shown below:
 1. You must apply the Addition property of equality and add 13 to both sides of the equation. Then:
 
 2. Finally you need to apply the Subtraction property of equality and subtract "x" from both sides of the equation. So you get:
 
 Therefore, as you can observe, the given equation has no solutions.
 
        
             
        
        
        
Answer:19. 17 degrees
20. 49 degrees
Step-by-step explanation:
Because of the postulate 50+?=67
So ?=17
And 20.
94+?=143
So
?=49
(Edit)I though you only meant 19 and 20
21. X=8
22. X=12
23.x=8
24.x=7

- Surface Area of a Sphere: SA = 4πr²
- Diameter: d = 2r
Step-by-step explanation:
<u>Step 1: Define</u>
SA = 23 in²
<u>Step 2: Find </u><em><u>r</u></em>
- Substitute [SAS]:                    23 in² = 4πr²
- Isolate <em>r </em>term:                         23 in²/(4π) = r²
- Isolate <em>r</em>:                                  √[23 in²/(4π)] = r
- Rewrite:                                   r = √[23 in²/(4π)]
- Evaluate:                                 r = 1.35288 in
<u>Step 3: Find </u><em><u>d</u></em>
- Substitute [D]:                    d = 2(1.35288 in)
- Multiply:                              d = 2.70576 in
- Round:                                d ≈ 3 in
