What is .24 as a whole number?
what is 2(3+6) - 4......................
Answer:
14
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
You have to use PEMDAS, so first you do the parentheses, (3+6)=9. Then you multiply 2 times 9=18. The last step is to subtract 4, so 18-4=14
(hope this helps!)
You can use the blank to remove parentheses in the process of solving the equation -10(x + 5) = 40 its a vocab pls help me
-10(x + 5) = 40
-10x - 50 = 40
+50 +50
-10x = 90
/-10 /-10
x = -9
Hope this helped! :D
Can someone solve this pls

Distributive property means
Answer:
according to
Step-by-step explanation:
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Answer:
8.67 dollars per ft squared
Step-by-step explanation:
This is a fraction equal to
130 dollars ÷ 15 ft squared
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 15
130 dollars ÷ 15
15 ft squared ÷ 15
=
8.67 dollars
1 ft squared
=
8.67 dollars
ft squared
= 8.67 dollars per ft squared
Answer:
$8.67
Step-by-step explanation:
you have the the price for 15 square ft
and you are trying to get the price for 1 square ft
just divide the original price by 15
here's the equation format
130 = 15 x
solve for x

Help please explain pythagorean theorem
Answer:
In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:[1]
{\displaystyle a^{2}+b^{2}=c^{2},}a^{2}+b^{2}=c^{2},
where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides. The theorem, whose history is the subject of much debate, is named for the Greek thinker Pythagoras, born around 570 BC.
The theorem has been proven numerous times by many different methods—possibly the most for any mathematical theorem. The proofs are diverse, including both geometric proofs and algebraic proofs, with some dating back thousands of years.
The theorem can be generalized in various ways: to higher-dimensional spaces, to spaces that are not Euclidean, to objects that are not right triangles, and to objects that are not triangles at all but n-dimensional solids. The Pythagorean theorem has attracted interest outside mathematics as a symbol of mathematical abstruseness, mystique, or intellectual power; popular references in literature, plays, musicals, songs, stamps, and cartoons abound.-Wikipedia

The force, F (Newtons), between two objects is inversely proportional to the square of the distance, d (metres), between them.
The force is 0.006 Newtons when the distance between the objects is 4 metres.
Work out d (rounded to 2 DP) when F=0.045 Newtons.
Answer:
d = 1.46 m
Step-by-step explanation:
We'll begin by obtaining the relationship between the force (F) and the distance (d). This can be obtained as follow:
From the question given above,
F is inversely proportional to square of d. This can be written as:
F ∝ 1/d²
F = K/d²
Cross multiply
K = Fd²
But:
Force (F) = 0.006 N
Distance (d) = 4 m
Constant (K) =?
K = Fd²
K = 0.006 × 4²
K = 0.006 × 16
K = 0.096 Nm²
Therefore, the relationship between the force (F) and the distance (d) is:
F = K/d²
F = 0.096 / d²
Finally, we shall determine the distance when the force is 0.045 N. This can be obtained as follow:
Force (F) = 0.045 N
Constant (K) = 0.096 Nm²
Distance (d) =?
F = K/d²
0.045 = 0.096 / d²
Cross multiply
0.045 × d² = 0.096
Divide both side by 0.045
d² = 0.096 / 0.045
Take the square root of both side.
d = √(0.096 / 0.045)
d = 1.46 m.

Fancy Nails charges $28 for a pedicure plus $9 for each treatment. Lara's Nails charges $22 for
a pedicure plus $11 per treatment.
How many treatments need to be purchased for the cost at both places to be the same?
(Use the system of equations below) *
(1 Point)
y = 9x + 28 & y = 11x + 22
Answer:C.4
Step-by-step explanation:
Answer:
It's B.3
Step-by-step explanation:
Substitution. With the equation Y= 9x+28 and Y= 11x+22, you substitute the x-factor with '3'. Which will give you
Y= 9(3)+28 Y= 11(3)+22
Y= 27+28 Y= 33+22
Y= 55 Y= 55
I don’t know the answer to this question, I need help the question is in the picture!
Answer:
it is 112° .. as you will solve it like this (180-44=136) and each angle down there are equal so we will divide 136÷2 so each angle is 68° ,, finally to find x you can do it in two ways 1) (68+44) =112 or you can go with (180-68=112)
A specific type of financial instrument pays 15% simple interest (based on the purchase value) and lasts for 1.5 years. The instrument can be bought at any price. An investor purchases the instrument for P0, and has calculated that the total value of the investment (i.e. P0 plus interest earned) will be $4,000 at maturity.
Answer:
Correct answers:
$3265$
For this, we can use the formula
A=P0(1+rt).
We know that A=$4,000,r=15%=0.15 and t=1.5, so we can rearrange the formula for A to give
P0=A1+rt,
and substituting the known quantities gives
P0=$4,0001+0.15×1.5=$4,0001.225=$3,265.30..,
which is $3,265 to the nearest dollar.

• How can the product of two whole numbers (e.g., 48
and 19) help us find the product of two decimals with
the same digits (e.g., 0.048 and 1.9)? Write your
explanation in the text box.
Let's say we already did the work and found the result of 48*19. That result is 912.
When it comes to multiplying 0.048 and 1.9, we're going to need to do two things to transform those numbers into 48 and 19.
Move the decimal point of 0.048 exactly three spaces to the right. This is the same as multiplying by 1000. So 1000*0.048 = 48
Move the decimal point of 1.9 exactly one space to the right. This is the same as multiplying by 10. So 10*1.9 = 19
Overall, we've multiplied by 1000*10 = 10,000. This means 48*19 = 912 is 10,000 times larger compared to the result of 0.048*1.9
To fix this, we need to divide by 10,000 to get 912/(10,000) = 0.0912
Dividing by 10,000 is the same as moving the decimal point to the left four spaces. Note how 10,000 = 10^4.
I recommend using your calculator to see that 0.048*1.9 = 0.0912 which matches with the previous result we got.
