Please teach me how to do this question..tq​

Answer:

Emilia bought 28 sweets

Step-by-step explanation:

now they have 65, but before they had 65-15+10 because earlier, zakiah had ten more sweets than now and Emilia had 15 less, so basically, if you wanna calculate number of sweets they had earlier, you have to make minus from plus and in reverse too.

65-15+10=60 and now just do that simply ratio

E:Z=7:8

E+Z=7x+8x

60=15x

4=x

7x=28=Emilia

8x=32=Zakiah

Accuracy test:

(28+15)+(32-10)=65

28 is 4•7 and 32 is 4•8

Who can help me please
lakkis [162]
The dimensions of the bottom of the drawer are:
20 cm × 40 cm

So the area is : 800 cm² (rectangular shaped)

The area formula of a circle is:
\pir²
The diameter of the plate is 20cm
so the radius is half the diameter which is 10cm
Apply the given to the formula:
\pi(10)²
100\pi
314.16 cm²

2 plates in the bottom drawer
Area of two plates:
2 × 314.16
628.32 cm²

Area of the non-covered space in the bottom drawer:
Area of drawer - area of two plates
800 - 628.32
171.68 cm²

Can someone help me find the slope , y-intercept ,and equation pls help it’s my finals
Likurg_2 [28]

Answer:

slope: -3

y-intercept: -5

equation: y = -3x - 5

Step-by-step explanation:

The formula for slope is:

(y2 - y1)/(x2 - x1)

Let's use these coordinates:

(-1, -2)

(0, -5)

x1 = -1

x2 = 0

y1 = -2

y2 = -5

Substitute into the formula:

(y2 - y1)/(x2 - x1)

(-5 + 2)/(0 + 1)

Solve:

(-5 + 2)/(0 + 1)

-3/1

= -3

slope = -3

The y-intercept is when the x coordinate is 0.

Looking at the table, we see the coordinate (0, -5).

The y-coordinate is -5.

This means that the y-intercept is -5

y-intercept = -5

Slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept

m = -3

b = -5

Substitute:

y = mx + b

y = -3x - 5
