Answer:

80/45 or 1 35/45 simplifed to to 1 7/9

Step-by-step explanation:

do 8/15 times 10/3

8 times 10 is 80

15 times 3 is 45

so 80/45 then make into mixed number

Answer:

$1\frac{7}{9}$

Step-by-step explanation:

$\frac{5}{15} *3 \frac{1}{3} \\$

Turn the second part into an improper fraction by multiplying the coefficient (the big 3) by the denominator of the fraction. You should get 3*3 = 9. Then add that number to the numerator of the fraction to get this:

$\frac{8}{15} * \frac{10}{3}$

Now, multiply directly across, so 8*10 over 15*3.

$\frac{8*10}{15*3}$ Now multiply out: $\frac{80}{45}$

You can simplify this into $\frac{16}{9}$

Now, see how many times the denominator goes into the numerator evenly (1 time) and subtract that from the numerator to get $1\frac{7}{9}$

How to solve this problem

Pavlova-9 [17]

For this one you can use 3/8 + 3/8 since 3+3 is equals to 6 and the 8 stays as it is.
I hope this helps.

What is the answer to this question

Lesechka [4]

Remark

There's a lot you don't know here. Are DE and GF parallel? Is B a right angle? You can't assume that it is. The safest way to proceed is to give x in terms of 58 and B. You might get an answer that gives you something like 32 but I don't think you can say that unless you are told somewhere that ABC is a right angle triangle with the right angle at B.

So what to do.

<BAC = 58o That's because <BAC = <IAK They vertically opposite.

<ABC + <BAC + <ACB = 180o All triangles have 180o

<ACB = 180 - 58 - <ABC Solve for an unknown angle of a triangle.

<ACB = 122 - <ABC

x = <ACB Vertically opposite angles.

x = 122 - <ABC Answer It's 32 if ABC is a right angle.

Use the line of best fit to predict the percentage sales increase when the

agasfer [191]

Answer:

107%

Step-by-step explanation:

because if we look at the x-axis, Discount (%)

and look at 35 which is between 30 and 40

and start going up we get near 100

107%

or?

we use the two points and with that we find the slope first

$\frac{y2-y1}{x2-x1}$

plug in (20,62) and (10,32)

$\frac{32-62}{10-20}$

equals

$\frac{-30}{-10}$

simplify to 3

then we use

y - y1 = m (x - x1)

y - 62 = 3 (x - 20)

y - 62 = 3x - 60

add 60 from both sides

y - 2 = 3x

add 2 to both sides

y=3x+2

then plug in 35

y= 3(35) + 2

which is

107

In the given diagram , TY is a tangent to the circle TVS . If <SVT = 48° and |VS| = |ST| . What is < VTY.

ycow [4]

Answer:

84°

Step-by-step explanation:

∠VTY is the tangent chord angle

Tangent chord angle is the half of the intercepted arc

∠TSV is the inscribed angle.

Inscribed angle is the half of the intercepted arc

Since both of the mentioned angles refer to same arc, they are of same value.

∠VTY = ∠TSV

ΔTVS is isosceles as VS = ST, therefore the opposite angles are same.

m∠T = m∠V = 48°

The measure of angle S

m∠S = 180° - 2*48° = 84°

The required angle

m∠VTY = 84°

To plot the point (5, -3) you would move up 5, then left 3. True False

frozen [14]

Hey there! :)

Answer:

False.

Step-by-step explanation:

In a point, the coordinates are in the format:

(x, y).

In this instance, x = 5 and y = -3. This means that to plot the point, you would need to:

Move right 5, down 3.
