Answer: 1.23
Step-by-step explanation:
0.3*4.1=
Answer:
It is 1.23
Step-by-step explanation:
When multiplying decimals, multiply it as a whole number, and move the decimal to the left the amount of times it was in the problem.
i.e. .3 times 4.1
.3 has 1 number behind the decimal and 4.1 also has one number behind the answer. This means that you will move the decimal to the left twice in 123.0 to 1.23
Hey guys can one of you help me pls it’s only one small question
Answer: x=6
Step-by-step explanation:
-6x+8=4(5-x)
-6x+8=20-4x
12=2x
x=6
Answer:
-6
Step-by-step explanation:
-6x+8=20-4x
subtract 8 from both sides:
-6x+8-8=20-4x-8
simplifiy:
-6x=-4x+12
Add 4x to both sides:
-6x+4x=-4x+12+4x
simplifiy:
-2x=12
divied both sides by -4:
-2x/-2=12/-2
simplifiy:
x=-6

Find the formula for the area A and the perimeter P of the shape shown find the area and perimeter when R is 5 cm find R when A is 100cm2 find r when P is 50cm find the value of r that makes A = p numerically
Answer:
1)Area; A = ¼πr²
Perimeter; P = πr/2 + 2r
2)A = 19.63 cm²
P = 17.85 cm
3) r = 8.885 cm
4) r = 14 cm
Step-by-step explanation:
This is a quadrant of a circle. Thus;
Area of a circle is πr². A quadrant is a quarter of a circle. Thus;
Formula for Quadrant Area is; A = ¼πr²
A) Perimeter of a circle is 2πr. Thus, perimeter of a quadrant is a quarter of the full circle perimeter.
Formula for the quadrant perimeter in the image given is;
P = 2πr/4 + 2r
P = πr/2 + 2r
B) When r is 5 cm;
A = ¼π(5)²
A = 19.63 cm²
P = π(5)/2 + 2(5)
P = 17.85 cm
C) when A is 100cm²:
¼πr² = 100
r² = 100 × 4/π
r² = 78.9358
r = √78.9358
r = 8.885 cm
D) when P = 50 cm.
50 = πr/2 + 2r
50 = (½π + 2)r
r = 50/(½π + 2)
r = 14 cm
Hey guys ( or gals ) I have no idea what to do please help me.
Answer:
Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.
You would have to find a GCF (greatest common factor) and multiply it out of the radical.
ex.
[tex]\sqrt{6}[/tex] = 2 x 2 x 2
when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2
2[tex]\sqrt{2\\}[/tex]
so [tex]\sqrt{6}[/tex] would be closest to the positive 2 on the number line and 2 notches.
[tex]\sqrt{11}[/tex]
is an irrational number, so it might fall into 3.3 if turned into a decimal.

The local lighting company found that 2 out of every 10 lightbulbs was defective. If
there are a total of 120 bulbs in a box, how many can they predict will be defective?
Answer:
24
Step-by-step explanation:
2/10
120 ÷ 10 = 12
2 x 12 = 24
10 x 12 = 120
24/120
Answer:
24
Step-by-step explanation:
120 % 10 = 12
2 x 12 = 24
An architect draws a plan for a wheelchair ramp on the plan, the ramp is 2cm high and 24cm long what might the dimensions of the actual ramp be (use equivalent ratios)
Answer:
[tex]Height = 30cm[/tex]
[tex]Length = 360cm[/tex]
Step-by-step explanation:
Given
Scale Measurement
[tex]Height = 2cm[/tex]
[tex]Length = 24cm[/tex]
Required
Determine the possible actual measurement
First, calculate the equivalent ratio.
[tex]Ratio = \frac{Length}{Height}[/tex]
[tex]Ratio = \frac{24cm}{2cm}[/tex]
[tex]Ratio = 12[/tex]
To do this, we pick a scale factor.
Assume the scale factor is 15.
The actual measurement will be:
[tex]Height = 2cm * 15[/tex]
[tex]Height = 30cm[/tex]
[tex]Length = 24cm * 15[/tex]
[tex]Length = 360cm[/tex]
When the scale ratio is calculated, we have:
[tex]Ratio = \frac{Length}{Height}[/tex]
[tex]Ratio = \frac{360cm}{30cm}[/tex]
[tex]Ratio = 12[/tex]
Note that both have the same equivalent ratios of 12.
So, whatever the scale ratio you use, the equivalent ratio will be the same
Solve for x, using the exterior angle theorem.
Answer:
x=121 degrees
Step-by-step explanation:
The extetior angle theorem states that one exterior angle is equivalent to the sum of the opposite two interior angles. So, we can say that x is the sum of the opposite two interior angles, (53 and 68), and 53+68=121.

A scuba diver descends below the surface of a lake at a rate of 12 feet per minute. What integer represents the depth of the diver after 4 minutes?
Since this scuba diver descends below the surface of a lake at a rate of 12 feet per minute, an integer which represents the depth of the diver after four (4) minutes is 48 feet.
What is the rate of change?The rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.
Mathematically, the rate of change for the depth covered by this scuba can be calculated by using this formula;
Rate of change = Depth/time
Making depth the subject of formula, we have:
Depth = Rate of change × time
Substituting the given parameters into the formula, we have;
Depth = 12 × 4
Depth = 48 feet.

if the product of two number is 10 and the sum is 7 ,then the longest of the two number is
Answer:
5 units
Step-by-step explanation:
Step one:
Given data
Le the first number be x
and the second number be y
So
x*y= 10-----------------1
and
x+y= 7-----------------2
from eqn 1
x= 10/y
put x= 10/y in eqn 2
[tex]10/y+y= 7\\\\10/y= 7-y[/tex]
cross multiply we have
[tex]10=y(7-y)\\\\10=7y-y^2[/tex]
rearrange
[tex]y^2-7y+10=0[/tex]
the factors of the quadratic expression are
-5 and -2
[tex]y^2-5y-2y+10= 0\\\\y(y-5)-2(y-5) =0\\\\y-2=0\\\\y= 2\\\\y-5= 0\\\\y=5\\\\[/tex]

John's bank account had $1,320 at the end of November. In December, he bought $645 worth of
groceries and spent $225 on his mom's birthday present. Luckily, he earned $350 mowing lawns and $50
for good grades. How much money does John have at the end of December?
Answer:
850 but im not sure lol
Step-by-step explanation:
645 + 225 = 870
1,320 - 870 = 450
450 + 350 = 800
800 + 50 = 850
It’s an inequality I need the work for it ik the answer
Answer:
Solving the inequality [tex]1<\frac{a+7}{-2}[/tex] we get the value of a: [tex]\mathbf{a<-9}[/tex]
Step-by-step explanation:
We need to solve the inequality: [tex]1<\frac{a+7}{-2}[/tex]
We need to solve the inequality, to find the value of a.
Solving the inequality:
[tex]1<\frac{a+7}{-2}[/tex]
First step is Switching both sides (the inequality will be reversed)
[tex]\frac{a+7}{-2}>1[/tex]
The next step is to multiply both sides by -2 and reverse the inequality
[tex]\frac{a+7}{-2}*-2<1*-2\\a+7<-2[/tex]
Now, subtracting 7 on both sides
[tex]a+7-7<-2-7\\a<-9[/tex]
So, solving the inequality [tex]1<\frac{a+7}{-2}[/tex] we get the value of a: [tex]\mathbf{a<-9}[/tex]

z = 106
y = 74
Since angle 74 and angle y are the same sizes, you can know for a fact they are the same measurments. Next, you would do 74(2) and that would get you 148. 360 - 148 is 212. 212/2 is 106. TADAAAAA. That's the answer.
