1 answer:
taurus [48]2 years ago
4 0

Answer:

3. 16.67

4. 25

Step-by-step explanation:

3. x+2÷8=14/6 (similar triangles have corresponding proportional sides)

x+2=(7×8)/3

x=56/3-6/3 (LCM)

x= 50/3

4. 27/72= (-4+4x)/64

3/2= (-1+x)/16

-1+x=24

x=24+1

4x + 8y=20<br> 3x+6y=15<br> solve this system of equations
laila [671]
4x=20-8y

x=5-2y now use this value of x in the second equation...

3(5-2y)+6y=15

15-6y+6y=15

15=15  This is true for any y or x value.

So there are infinitely many solutions as the two equations describe the same line.

What is the relationship between the degree measure of the angle formed by the straight edges of a section of a circle graph as
Butoxors [25]

Answer:

  degree measure = 360° × percent of data

Step-by-step explanation:

The ratio of the degree measure of a sector of a circle graph to 360° is the same as the ratio of the represented data to the whole amount of data.

The idea of a circle graph is that the area of the sector is proportional to the data being represented. That is, if the data represented is 10% of the whole, then the sector area is 10% of the whole. Sector area is proportional to the degree measure of its central angle, so the example sector would have a central angle of 10% of 360°, or 36°.

The ratio of the central angle of the sector to 360° is the same as the percentage of data that sector represents.

Find the x-intercept and the y-intercept of 2x + 6y =24
viktelen [127]

Answer:

x-intercept = 12, y-intercept = 4

Step-by-step explanation:

To find the x and y intercept, substitute 0 in for both values.

<u>Substitute 0 into x:</u>

2(0) + 6y = 24

6y = 24

<u>Divide each side by 6:</u>

y = 4

<u>Substitute 0 into y:</u>

2x + 6(0) = 24

2x = 24

<u>Divide each side by 2:</u>

x = 12

Mr Taylor brought back 180 Euros to the UK. The exchange rate was €1.2 to £1.
solong [7]
The answer is £150.

This could be calculated using proportion. If £1 is €1.2, how many £ is €180:
£1 : €1.2 = x : <span>€180
</span>x = £1 ÷ €1.2 × <span>€180</span>
x = £150
