Answer:
The full mass is 500 kg.
Step-by-step explanation:
Let's break this down.
4% of the mass is 20 kg.
4% = 4/100 or 0.04
"of" = multiply
mass = our unknown value, x
is = equal sign
20 kg = our end result
Let's make an equation out of this.
4% of the mass is 20 kg.
0.04 • x = 20
Divide both sides by 0.04.
x = 500
The full mass is 500 kg.
Hope this helps!
Answer:
500 kg
Step-by-step explanation:
4% = 20 kg
→ Find 1% by dividing both sides by 4
1% = 5 kg
→ Find 100% by multiplying both sides by 100
100% = 500 kg
The Peak Library Book Club was doing a bake sale. Their goal was $550 for the entire week. The sale has lasted 4 days so far and each day they raised about $135.50. Will they make their goal by day 4? If not, how much do they need on day 5 to meet it?
Answer: See explanation
Step-by-step explanation:
Since their goal was $550 for the entire week and the sale has lasted 4 days already and each day they raised about $135.50, the amount raised for the 4 days will be:
= $135.50 × 4
= $542.00
No, they won't make their goal by the 4th day.
The amount needed on the 5th day will be:
= $550 - $542
= $8
They'll need $8 on the 5th day.

6 x [(16 + 29) / 9 -3]
Answer:
45
Step-by-step explanation:
6 × [45 / 9-3]
6×45/6
270/6
45
Answer:
45
Step-by-step explanation:
6 x (16 + 29) / 9 - 3)
16 + 29 = 45
9 - 3 = 6
45/6 = 7.5
6 x 7.5 = 45

We add the scale factor to each length of an image to get the scaled copy.
-True or False?
Answer:
false
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
original dimensions / scale of the drawing = dimensions of the scale drawing
To scale an image, divide the original length by the scale
for example the length of the image is 100 and the scale factor is 4
the length of the scale copy = 100/4 = 25

Help!!!!!!!!!!plz!!!!!!!!!!!!
Answer:
16
Step-by-step explanation:
By intersecting secants theorem:
[tex]9(2x - 17 + 9) = 8(8 + 10) \\ \\ 9(2x - 8) = 8 \times 18 \\ \\ 2x - 8 = \frac{144}{9} \\ \\ 2x - 8 = 16 \\ \\ 2x = 16 + 8 \\ \\ 2x = 24 \\ \\ x = \frac{24}{2} \\ \\ x = 12[/tex]
CE = 9 + (2x - 17)
CE = 9 + (2*12 - 17)
CE = 9 + (24 - 17)
CE = 33 - 17
CE =16

Beth says 20-5x3 is 45, pat says 20-5x3 is 5. who is right?
Answer:
Pat is right
Step-by-step explanation:
first multiply/divide then add/subtract,
Beth: 20 - 15 = 45 => 5 ≠ 45
Pat: 20 - 15 = 5 => 5 = 5
Answer:
Pat
Step-by-step explanation:
There is only one correct answer. To find it, you must follow the correct order of operations.
There is a subtraction and a multiplication. There are no parentheses.
The rule is that you must do the multiplication before the subtraction.
20 - 5 * 3 =
= 20 - 15
= 5
In order to get Beth's answer, you'd have to do the subtraction first. If there were parentheses like this: (20 - 5) * 3, then you'd do the subtraction first getting 15 * 3 which is 45, but the problem has no parentheses, so the correct answer is 5.
The correct answer is 5, and Pat is correct.

How do I solve this arithmetic sequence and find the next four terms?
Answer:
252
Step-by-step explanation:
t50 = t1 + (n - 1)(d)
= 7 + (50 - 1) (5)
= 7 + (49)(5)
= 7 + 245
= 252
Answer:
The 50ᵗʰ term of this sequence is 252
Step-by-step explanation:
Here,
First Term = a₁ = 7
Common Difference = (d) = 5
Now, For 50ᵗʰ term, n = 50
aₙ = a + (n - 1)d
a₅₀ = 7 + (50 - 1) × 5
a₅₀ = 7 + 49 × 5
a₅₀ = 7 + 245
a₅₀ = 252
Thus, The 50ᵗʰ term of this sequence is 252

What is the value of x in a 45-45-90 triangle and the hypotenuse is 4?
9514 1404 393
Answer:
x = 2√2 ≈ 2.83
Step-by-step explanation:
The side length of an isosceles right triangle is 1/√2 times the hypotenuse length. If x is the side length, then ...
x = 4/√2 = 4(√2)/2
x = 2√2 ≈ 2.83

1 What is the solution to the system of equations? (2 Points) x + y = 8 and - x + 3y = 4 O a. (-2, 10) O b. (10,-2) c. (3,5) O d. (53)
Answer:
(5 , 3)
Step-by-step explanation:
x + y = 8 ----------------(I)
-x + 3y = 4 ----------(II)
Add equation (I) and (II) and so x will be eliminated and we can find the value of y
(I) x + y = 8
(II) -x + 3y = 4
4y = 12 {Divide both sides by 4}
y = 12/4
y = 3
Plugin y = 3 inn equation (I)
x + 3 = 8 {Subtract 3 from both sides}
x = 8 -3
x = 5
