Step-by-step explanation:

It's hard to tell what you mean. I'm going to assume you mean that you want what is left to be 3/7 less.

1400 - 3/7 1400 = 1400 - 600 = 800

The value of R1400 when decreased by the ratio 7:3 is  R600.

Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained in another value.

R1400 X 3/7 = R600

Answer:

C

Step-by-step explanation:

first we want to find the missing angle at the top

to do that we subtract the given angles by 180

the square indicates that the angle is a right angle or that it equals 90

180-90-40=50

we know that the angle equal to 50 and x are supplementary angles so they will add up to equal 180 so to find x we subtract 50 from 180

180-50-130 so the answer is c

Answer:

For the regular tax in Pennsylvania, it would be 12 cents or $0.12. For Philadelphia, it would be 4 cents or $0.04. I got these two amounts by multiplying 2 times 6 or 2 percent, aka 0.06 and 0.02. If you added the two together, you would get, $0.16 or 16 cents. You would then add that to the two dollars and end up with $2.16 or two dollars and sixteen cents. I hope this helps.

Answer: A. X > 14

Step-by-step explanation:

1. 10x > 140. We need to eliminate that 10 so it is just X. So, we divide both numbers.

2. 10 / 10 = 1, so it just becomes x

3. Now, we divide the other side.

140 / 10 = 14

Answer:

n = -6

Step-by-step explanation:

n -12 = 3n

2n = -12

n = -6

Answer:

n=-6

Step-by-step explanation:

So first, you should subtract n from both sides to isolate the number -12. This will make the equation look like 2n=-12. Divide both sides by 2 because you want n to be by itself. This will give you the answer n=-6

Answer:

Diagonal of the rectangle = 13 units   c =13

side of rectangle = 12 units         a = 12

area of the rectangle = l× b

In rectangle all the corner angle is 90 degree. A diagonal of the rectangle forms two right angle.so we use Pythagoras theorem.

formula ; a²+b²=c²    a = 12 , c = 13

             12²+b² = 13²

            144 + b² = 169

            b² = 169 - 144

                =25

b   = 5 units

a  = 12 units

Step-by-step explanation:

Points: (7, -4) and ( -1, 2)

Slope:

m=(y2-y1)/(x2-x1)

m=(2+4)/(-1-7)

m=6/(-8)

m= -3/4

Slope-intercept:

Answer:

[tex]\boxed{x=73.74}[/tex]

[tex]\boxed{y=16.26}[/tex]

[tex]\boxed{z=25}[/tex]

Step-by-step explanation:

Hello there!

Algebra 1

The first thing we should find is the missing angle

Because this is a right triangle we can solve it using the Pythagorean Theorem

The Pythagorean theorem states that the sum of the two legs squared equal the hypotenuse squared

the formula... [tex]a^2+b^2=c^2[/tex] where a and b = legs and c = hypotenuse

we are given two legs so we plug in a and b and solve for c

[tex]7^2+24^2=c^2\\7^2=49\\24^2=576\\576+49=625\\625=c^2\\\sqrt{c^2} =c\\\sqrt{625} =25\\c=25[/tex]

so we can conclude that the missing side length ( or z) equals 25

now to solve for the angles

Trigonometry

We can solve for y using sin

sin = opposite side divided by the hypotenuse

the opposite of y is 7 and the hypotenuse is 25

so we set up an equation [tex]sin(y)=\frac{7}{25}[/tex]

now we solve for y

[tex]\frac{7}{28} =.28\\arcsin(y)=y\\arcsin(.28)=16.26020471[/tex]

then we round to the nearest hundredth

so we can conclude that angle labeled y = 16.26

basic geometry

Remember all of the angles in a triangle add up to equal 180 so we can find x by subtract the known angles from 180

180 - 90 - 16.26 = 73.74 so we can conclude that x = 73.74

this doesn't make sense

Answer:

an octagon has 8 sides

8 x 7 = 49 inches

Step-by-step explanation:

The misrepresentation lies in the fact that ; The graphs use different scales, making it appear that the prices at TechPlus are much lower than CompStar.

Taking a look at both graphs, it could be observed on the y - axis that the graphs do not follow the same scale.

For CompStar, the y-axis which shows the price of laptops and desktops starts it's labeling from $0 ; while TechPlus's labeling began from $600

This representation means that comparing the two graphs would give an erroneous inference as it would make the price of TechPlus appear lower than that of Complus.
