1. A limited-edition soccer ball costs $30, and the
sales tax is 6%. What is the total cost?
Answer:
$31.80
Step-by-step explanation:
The ball will cost 100% of its price plus 6% of its price for a total of 106%.
To use percentages as a factor and multiply, they must be divide by 100, making the multiplication factor version of 106% 1.06.
Multiply the cost of the ball by your multiplication factor:
30 x 1.06 = 31.8
Money is written to two decimal places, making your answer $31.80
Answer:
$31.80
Step-by-step explanation:
First, find how much the sales tax is
$30 × 6%
Convert the percentage into a decimal
30 × 0.06
1.8
$1.80
Add the sales tax to the original cost
$30 + $1.80
$31.80

X=5 and 3
Answer: a. x=3 or 5
Step-by-step explanation:
x^2-8x+15=0
When factoring this equation we need to find 2 numbers that multiply to get positive (15) and add to get negative (-8)
So -3 and -5 fit this description because -3+-5=-8 and -3*-5=15
(x-3)(x-5)=0
Solve for values of x to get x=3 and x=5
so X=3 or 5
A large emerald with a mass of 982.7 grams was recently discovered in a mine. If the density of the emerald is 2.76 grams over centimeters cubed, what is the volume? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.
Answer:
356.05 cm³
Step-by-step explanation:
We are looking for the volume. The formula is density = mass / volume.
If we plug in our numbers, our formula would be 2.76 = 982.7 / V.
Multiply both sides by V and your formula would be (V) 2.76 = 982.7.
Divide both sides by 2.76 and you would get V = 356.05.
The volume of the given large emerald is required.
The volume of the given large emerald that was discovered in the mine was 356.05 cm³. The calculations to find this value is shown below.
Densitym = Mass of object = 982.7 grams
[tex]\rho[/tex] = Density of the material the object is made of = 2.76 grams over centimeters cubed
The relation between mass, volume and density is given by
[tex]V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{982.7}{2.76}\\\Rightarrow V=356.05072\approx 356.05\ \text{cm}^3[/tex]

If triangle ABC is an equilateral triangle and the measure of angle A is
5x, what is the value of x?
Answer:
A not enough
Step-by-step explanation:
someone help please!!!!!
Answer:
x = 5
Step-by-step explanation:
They are alternate interior angles so you can set them equal:
-5+13x= 60
13x = 65
x = 5
60 + -5 + 13x = 120
13x + 55 = 120
13x = 65
x = 5

The length of a road on the map is 7 cm.
Work out the length, in kilometres, of the real road.
Answer:
2.1 Km
please look at the picture i sent ....
Based on the information given the length in kilometres of the road is 210,000.
Length in kilometres:Using this formula
Length in kilometres=Road map scale of map×Length of road map

Road map scale of map=30,000
Length of road map=7
Let p[lug in the formula
Length in kilometres=30,000×7
Length in kilometres=210,000 kilometres

Answer:
It is C.
Step-by-step explanation:
So,A triangle is equal to 180 and you would add up the numbers you already have which equal 145.180-145= 35° and thats why the last letter would be 35° in your answer and be correct which would be that m<F=35° is the same as ABC in the last letter. Since,<B is the second letter in ABC and so is <E in DEF and have the same degree that would be the same as well so I hope that helps:)
Answer:
c
Step-by-step explanation:
the angles in a triangle have to add up to 180°
65 + 80 = 145
180-145 = 35
the missing angle is 35°
choice c matches because it has 2 of the same angle measures, which means they all have to be the same

Use complete sentences to describe the steps involved in solving x2 − 64 = 0 two different ways.
Answer:
1. First, add 64 to bith sides, cancelling one out and taking it to the other side, then dividing by two, giving you x=32.
2. Subtract 2x and take it to the other sude of the equation. Then divide -2 by -64, giving you x=32, due to the negative cancelling (turning to a positive).

Find the measure of ZAOE in the diagram below.
90
100
120
130
========================================================
Explanation:
The three upper angles
AOBBOCCODall combine together to form a 180 degree straight angle. Let's add up the angle expressions and set the result equal to 180. That will help us solve for x.
(angle AOB) + (angle BOC) + (angle COD) = 180
(3x-28) + (90) + (66-x) = 180
2x+128 = 180
2x = 180-128 .... subtract 128 from both sides
2x = 52
x = 52/2 .... dividing both sides by 2
x = 26
Since x = 26, we can find the missing angles like so
angle AOB = 3x-28 = 3*26-28 = 50angle COD = 66-x = 66-26 = 40Note how:
(angle AOB) + (angle BOC) + (angle COD) = 50+90+40 = 180
to help confirm we have the correct x value.
--------------------------------------
Afterward, we need to find angle BOD which is the combination of angles BOC and COD
angle BOD = (angle BOC) + (angle COD)
angle BOD = 90 + 40
angle BOD = 130
Angles BOD and AOE are vertical angles. It might help to erase ray OC so you can see the two vertical angles better. Vertical angles are always congruent, which means angle AOE is 130 degrees as well.
