Answer:
71.2
Step-by-step explanation:
PEMDAS is Parentheses, Exponent, Multiplication, Addition, Subtraction
This is just the order you do the operations.
First, Parentheses.
Second, Exponents,
Third, Multiplication or Division
Last, Addition or Subtraction
So, in 6 x (2.4 + 10.3) - 5
We first do parentheses which is
(2.4 + 10.3) = 12.7
Now we have,
6 x 12.7 - 5
The next thing is multiplication
6 x 12.7 = 76.2
Now we have,
76.2 - 5
Lastly subtract,
76.2 - 5 = 71.2
Find the length of h. Round to the nearest hundreth.
Answer:
h = 0.24
Step-by-step explanation:
Assuming this is a parallelogram...
Sine trig ratio
[tex]\sin(\theta)=\sf \dfrac{O}{H}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuseLet x be the angle in the top left of the parallelogram.
[tex]\implies \sin(x)=\dfrac{0.3}{0.5}=\dfrac35[/tex]
Opposite angles in a parallelogram are congruent.
Therefore, the angle in the bottom right of the parallelogram is also x.
[tex]\implies \sin(x)=\dfrac{h}{0.4}[/tex]
[tex]\textsf{As} \:\sin(x)=\dfrac35[/tex]
[tex]\implies \dfrac35=\dfrac{h}{0.4}[/tex]
[tex]\implies h=\dfrac35 \cdot 0.4=0.24[/tex]
Remember (3,4,5) Pythagorean triplet
Triangle containing y
Hypotenuse=0.5Base=0.4Triangle containing x
Base=0.4Perpendicular=0.3Now use ratio to find
0.5/0.3=0.4/h5/3=0.4/h5h=1.2h=1.2/5h=0.24Hello, I was just doing some practicing for adding integers. I did some problems on my own and I was wondering if I am on the right track.
Answer:
Yes
Step-by-step explanation:
Is Okay.
but when the answer is a positive answer ignore the + sign
but if negative show it
apart from that it's all okay
Another math thing I need help with
Answer:
Step-by-step explanation:
This quadratic equation is given in standard form, which is [tex]y= ax^2 +bx+c[/tex]. The x-value of the vertex of a quadratic equation can be found using the given formula. Therefore, we can plug the the numbers given into the formula as such: [tex]x=\frac{24}{2(6)}[/tex]. This can be simplified into 2. Now that we have the x-coordinate, we can plug that back into the equation to find the y-coordinate: [tex]y=6(2)^2-24(2)+30[/tex]. This simplifies to y = 6. Therefore, the vertex of the equation is located at (2,6).

the town of abridge currently has a population of 300,000 each year the population will reduce by 7% how many fewer people will live in abridge in 5 years compared with now give your answer to 3 sf
Answer:
91,300 to 3 s.f.
Step-by-step explanation:
The population is reduced by a percentage 100-7 = 93% ( or 0.93) per year.
So after 5 years thatwould be 300,000(0.93)^5
= 208707
that is 300,000 - 208,706
= 91293
= 91,300 to 3 s.f.
Melissa made a paperweight. The paperweight is a rectangular prism. She painted the outside surface of the paperweight.
Solve the following....
[tex]x+4=3(x-2)[/tex]
Answer:
x = 5
Step-by-step explanation:
x + 4 = 3(x - 2) ← distribute parenthesis by 3
x + 4 = 3x - 6 ( subtract 3x from both sides )
- 2x + 4 = - 6 ( subtract 4 from both sides )
- 2x = - 10 ( divide both sides by - 2 )
x = 5
Answer:
Solution of equation is 5Step-by-step explanation:
In the question we have given an equation that is x + 4 = 3 ( x - 2 ) . And we are asked to solve the question that means we have to find the value of x .
Solution : -
[tex] \longrightarrow \quad \: x + 4 = 3(x - 2)[/tex]
Step 1 : Solving parenthesis on right side :
[tex] \longrightarrow \quad \: x + 4 = 3x - 6[/tex]
Step 2 : Subtracting 4 on both sides :
[tex] \longrightarrow \quad \: x + \cancel{4} - \cancel{ 4 }= 3x - 6 - 4[/tex]
On further calculations we get :
[tex] \longrightarrow \quad \: x = 3x - 10[/tex]
Step 3 : Subtracting 3x on both sides :
[tex] \longrightarrow \quad \: x - 3x = \cancel{3x } - \cancel{3x}- 10[/tex]
On further calculations we get :
[tex]\longrightarrow \quad \: - 2x = - 10[/tex]
Step 4 : Dividing both sides by -2 :
[tex]\longrightarrow \quad \: \dfrac{ \cancel{ - 2}x}{ \cancel{ - 2} } = \cancel{\dfrac{ - 10}{ - 2} }[/tex]
On further calculations we get :
[tex]\longrightarrow \quad \: \red{\underline\red{\boxed{ \frak{ x = 5}}}}[/tex]
Therefore , value of x is 5 .Verifying : -
We are verifying our answer by substituting value of x in given equation. So ,
x + 4 = 3 ( x - 2 )5 + 4 = 3 ( 5 - 2 )9 = 3 ( 3 )9 = 9L.H.S = R.H.S Hence, Verified.Therefore, our answer is correct .
#Keep LearningGIVING BRAINLEST TO THE PERSON THAT CAN EXPLAIN HOW TO DO THIS THE BEST :)
Answer:
196 - 49[tex]\pi[/tex]
i hope this helped :)
Step-by-step explanation:
first of all the explaination is to first find the area of the square and then the circle after you have found that you should subtract them and you will get the area of the shaded region.
radius x 2 = the side of the square
7 x 2 = 14
area of square - 14 x 14 = 196 squared
formula of finding the area of the circle - [tex]\pi[/tex]r^2
area of circle - 3.14 x 7 x 7 = 49[tex]\pi[/tex]
so answer simpliefied is 196 - 49[tex]\pi[/tex]

Given the graph above, choose the coordinate point that is NOT a
solution.
(6.0)
(10,6)
(-8,6)
(0,0)
Answer: Choice C
(-8, 6)
===============================================
Reason:
This point is not in the shaded region. Points in the shaded region are solution points to make the inequality true. Points on the dashed boundary line do not count as solution points.
Answer:
-8,6
Step-by-step explanation:
all of the other answers are within the highlighted area of tha graph and thus are solutions but -8,6 is outside the highlighted area

Alejandro will deposit $1,750 in an account that earns 6.5% simple interest every year. His sister Anallency will deposit $1,675 in an account that earns 7.5% interest compounded annually. The deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Which sibling will have more money at the end of four years?
Answer: Anallency
Step-by-step explanation:
First, lets make two equations for both siblings, using the base: SI = P(1 + rt) and CI = P(1 + r/n)^nt
Alejandro = 1750(1 + 0.065[4]) = 1750 + 455 = $2,205
Anallency = 1675(1 + 0.075/1)^4 = $2236.91
After 4 years, Alejandro will have $2,205, and Anallency will have $2236.91
Since $2236.91 > 2,205, Anallency will have more money after 4 years.
Answer:
Anallency will have mor money.
Step-by-step explanation:
Simple Interest:
I = Prt
I = $1750 × 0.065 × 4
I = $455
Total after 4 years: $1750 + $455 = $2205
Compound Interest:
F = P(1 + r/n)^(nt)
F = $1675(1 + 0.075)^(4)
F = $2236.91
Answer: Anallency will have mor money.

and this = 5 million.
The roof of castle is in the Shape of a cone. It has a height of 12 feet and a diameter of 6 feet, how much air occupies the roof? (Use PE= 3. 14 )
can someone answer this is that I do not understand and I need it.
Answer:
y = 110 degree
x = 70 degree
z = 70 degree
Step-by-step explanation:
Vertical angles are always congruent.
so, the angle with the 110 degree is equal to the angle y.
now we have the measure of y.
as you can see angle y and angle z form a straight light wich means the sum of angle y and angle x is 180 degree
now, to get the measure of angle z,
180 - 110 = angle z
70 = angle z
now we have the measure of angle z
as angle z and angle x are vertical angle, they are congruent.
so angle x = 70
x = 70
z= 70
y = 110

-1.6, 5/2, -7/8, 0.9, -6/5 from least to greatest
Answer:
starting with least...
-1.6
-6/5
-7/8
9/10
5/2
...to greatest.
Step-by-step explanation:
start by putting the decimals into fractions:
-1.6 = -8/5
0.9 = 9/10
and then find a common denominator to compare them fairly.
the number that they all end up going into is 40, which will be your common demoninator.
-8/5 (aka -1.6) = -64/40
5/2 = 100/40
-7/8 = -35/40
9/10 (aka 0.9) = 36/40
-6/5 = -48/40

Given circle E with diameter CD and radius EA. AB is tangent to E at A. if AD = 15 and EC = 14, solve for AC.
Answer:
AC ≈ 23.6 units
Step-by-step explanation:
m∠CAD = 90°
CD = 2×14 = 28 , AD = 15
CD² = AD² + AC² ⇒ AC² = CD² - AD²
AC² = 28² - 15² = ( 28 - 15 )( 28 + 15 ) = 13 × 43 = 559
AC ≈ 23.6
