Step-by-step explanation:

If price  of a sweater was reduced from $20 to $12 then the percentage was the price of the sweater reduced is 40%.

percentage, a relative value indicating hundredth parts of any quantity.

Given that the price of a sweater was reduced from $20 to $12.

Original price is 20.

new price is 12.

We have to find the how much  percentage was the price of the sweater reduced.

To do this we have to find the difference between prices over the original price and multiply with 100.

Percentage = 20-12/20×100

=8/20×100

=40%

Hence, if price  of a sweater was reduced from $20 to $12 then the percentage was the price of the sweater reduced is 40%.

Answer: x = - 5/2 five is on top and 2 is bottom

Answer:

49 = 7 x 7

Step-by-step explanation:

if we factor out 49 into its prime factors, we will get

49 = 7 x 7

(this is the answer)

Alternatively, we can recall from our multiplication tables that 49 = 7² = 7 x 7 (which gives the same answer)

Answer:

7² or 7x7

Explanation:

The prime is any number that can only be divided by itself or by one. One is not a cousin. The only prime pair is 2, all the others are unpaireds.

7/7 = 1. 7/1 = 7

7x7 = 49 or

7² = 49.

Other examples;

9 = 3²

25 = 5²

Step-by-step explanation:

im just diffrent

The required ratio for the burger is 3;6:9 and the ratio for the hot dog is 5:10:15.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Let the missing ratio in Burger be x and the ratio in the Hot dogs be y,
Now,
According to the question,
3 / 5 = x / 10
x = 6
Now,
x / 10 = 9  / y
Substitute the value of x,
6 / 10 = 9 / y
y = 90 / 6
y = 15

Thus, the required ratio for the burger is 3;6:9 and the ratio for the hot dog is 5:10:15.

Answer:

-6 or negative six in words

OPPOSITE OF A NUMBER IS ALSO KNOWN AS INVERSE

Answer:

-6

Step-by-step explanation:

Answer:

Yes, because lines m1 and m2 have the same slope of -2

Step-by-step explanation:

For given two lines L1 and L2 with slope m1 and m2 respectively, the condition for the two lines to be parallel is for the two equations to have the same slope. If m1 = m2, the meaning is that the line L1 and L2 are parallel to each other no matter the equation of the lines in question.

The general equation of a line is y = mx+c where;

m is the slope and c is the intercept.

Even though we are not given the equation of both lines, the base line is that for two lines to be parallel to each other, they must have the same slope.

The correct option is therefore "Yes, because lines m1 and m2 have the same slope of -2"

g(x)= x2

Step-by-step explanation:

g(x)=x2 = f(x)=x2

The graph of g is a vertical stretch by a factor of 2 followed by a translation of 3 units down of the graph of [tex]\rm f(x) = (x-1)^2[/tex] then the function  [tex]\rm g(x) = 2(x+4)^2[/tex].

Given :

The following steps can be used to determine the rule for g:

Step 1 - Rewrite the given function f(x).

[tex]\rm f(x) = (x-1)^2[/tex]

Step 2 - Now, the graph is stretched vertically by a factor of 2.

[tex]= 2(x-1)^2[/tex]

Step 3 - Now, reflect the graph about the y-axis.

[tex]=2(-x-1)^2[/tex]

Step-by-step explanation:

Answer:

7.3%

Step-by-step explanation:

to get this percentage, we need to use the z-score calculation;

z-score = (x-mean)/SD

mean = 25.10 , SD = 0.2

For diameter 24.60

z-score = (24.6-25.10)/0.2 = -0.5/0.2 = -2.5

For diameter 25.40

z-score = (25.4-25.1)/0.2 = 1.5

So the proportion that will satisfy the specifications will be;

P(-2.5 < z < 1.5)

At this point, we use the standard normal table

P(-2.5 < z < 1.5) = P (z<1.5) - P (Z < -2.5)

From standard normal table;

P(Z < 1.5) = 0.9332

P(z < -2.5) = 0.0062

P(-2.5 < z < 1.5) = 0.9332 - 0.0062 = 0.927

So the proportion that meets specification = 92.7% ( same as 0.927)

Proportion failing to meet specification = 100- 92.7% = 7.3%

Answer: The percentage of ball bearings fail to satisfy the contract specifaction is 7.3 %.

Step-by-step explanation:

First we need to find the standard score of 24.60 and 25.40. Using Standard Score formula.

[tex]\frac{24.60 - 25.10}{.20} =-2.5\\\\\frac{25.4 - 25.10}{.20}=1.5[/tex]

now we need to find the percentages of these Z scores.

-2.5 = .0062 or 00.62%

1.5 = .9332 or 93.32%

now we subtract these two to get the in between percentage.

.9332 - .0062 = .927 or 92.7% is what doesnt fail to satifsy the contract spefications! But to find what does fail to satisfy we have to subtract it by 100% or 1.

1 - .927 = 0.073

Answer:

ik that angle one would be the same as 3 and 2 and 4 are also the same so if u find an answer for 2 or 4 they would be the same but is there like a total of the entire thing

Answer:

Angle 1 = 72 degrees

Angle 2 = 110 degrees

Angle 4 = 110 degrees

Step-by-step explanation:

Use angle rules.

Angle 2 + angle 3 = 180, because they supplementary angles.  Therefore, to find angle 2, you can do 180 - 72 = 110 degrees.

Angle 1 and angle 3 are vertical angles, meaning they are equal.  Thus, angle 1 = 72 degrees.

Angle 2 and 4 are vertical angles, meaning they are equal.  Thus, angle 4 = 110 degrees.
