Answer:

a) 2.5^2+19\times2.5-16.75

Step-by-step explanation:

(2.5)² +(19× 2.5) - 16.75

= 6.25 + 47.5 - 16.75 = 37

Answer:

The left side

182

does not equal to the right side

450

, which means that the given statement is false.

False

Step-by-step explanation:

mark as brainliest!!

Answer= 268

Reason:-

Let The Missing Number be x

x+308-126=450

x+182= 450

x=450-182

x=268

Answer:

The greatest number of bags Lucia can make = 16

Each of the 16 bags will contain 4 stickers and 3 markers

Step-by-step explanation:

Markers = 48

Stickers = 64

What is the greatest number of bags Lucia can make?

Find the highest common factor of 48 and 64

48 = 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48

64 = 1, 2, 4, 8, 16, 32 and 64

The highest common factor of 48 and 64 is 16

The greatest number of bags Lucia can make = 16

Stickers = 64/16

= 4 stickers per bag

Markers = 48/16

= 3 markers per bag

Each of the 16 bags will contain 4 stickers and 3 markers

Answer:

yes

Step-by-step explanation:

I = 6750

P= 25000

r = 9% = 0.09

t=?

I= prt

6750 = 25000×0.09× t

t = 6750/25000"0.09 = 3

Answer - 3 years.

P = 8 + 10 + 8 + 10

P = 36

Answer:

Tangent

Step-by-step explanation:

Given

[tex]\angle C = 50[/tex]

See attachment for complete question

Required

Function to calculate BC

If AB is known, BC is calculated as:

[tex]\tan(C) = \frac{AB}{BC}[/tex]

Substitute d for AB and 50 for C

[tex]\tan(50) = \frac{d}{BC}[/tex]

Make BC the subject

[tex]BC = d * \tan(50)[/tex]

Hence, BC can be found using tangent

Answer:

Answer: m = 94 / 58 = 47 / 29 = 1.62069

Step-by-step explanation:

Answer:

47/29

Step-by-step explanation:

To find the slope between two points

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

   = ( 91- -3)/(81 - 23)

   = ( 91+3)/(81 - 23)

   = 94/58

   = 47/29

Answer:

Step-by-step explanation:

The standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex] where h and k are the coordinates of the center of the circle, and r is the radius squared. Our center is located at (-6, -4)  and from the center to the outer edge is 2 units, so the radius is 2-squaraed, which is 4. That makes the equation for this circle

[tex](x-(-6))^2+(y-(-4))^2=4[/tex] which simplifies to

[tex](x+6)^2+(y+4)^2=4[/tex]

Answer:

x < 6

Step-by-step explanation:

-3x > -18

Divide both sides by -3. (Remember to flip the > to <)

x < 6

Answer:

Numbner of plant in field = 2,020

Cost of planting trees = R.s 151,500

Step-by-step explanation:

GIven:

Side of square field = 45 m

Area of well = 5 square meter

1 plant = 1 squre meter

Cost per tree = R.s 75

Find:

Numbner of plant in field

Cost of planting trees

Computtaion:

Area of planting trees = Area of filed - Area of well

Area of planting trees = [45 x 45] - 5

Area of planting trees = 2,025 - 5

Area of planting trees = 2,020 squre field

Numbner of plant in field = Area of planting trees /  1 squre meter

Numbner of plant in field = 2,020

Cost of planting trees = 75 x Numbner of plant in field

Cost of planting trees = 75 x 2,020

Cost of planting trees = R.s 151,500

A = ( 4 , 3 ) ..**&**.. B = ( - 1 , 1 )

_____________________________

Slope = [ y(B) - y(A) ] ÷ [ x(B) - x(A) ]

Slope = [ 1 - 3 ] ÷ [ - 1 - 4 ]

Slope = [ - 2 ] ÷ [ - 5 ]

Slope = 2/5

______________________________

y - y(0) = Slope × ( x - x(0) )

y - y(A) = Slope × ( x - x(A) )

y - 3 = 2/5 × ( x - 4 )

y - 3 = 2/5 x - 8/5

y = 2/5 x - 8/5 + 3

y = 2/5 x - 8/5 + 15/5

y = 2/5 x + 7/5

Answer:

[tex]\cos(\theta_1) = \frac{\sqrt{111}}{20}[/tex]

Step-by-step explanation:

Given

[tex]\sin(\theta_1) = \frac{17}{20}[/tex]

[tex]Quadrant = 1[/tex]

Required

[tex]\cos(\theta_1)[/tex]

We know that:

[tex]\sin^2(\theta_1) + \cos^2(\theta_1) = 1[/tex]

This implies that:

[tex](\frac{17}{20})^2 + \cos^2(\theta_1) = 1[/tex]

Collect like terms

[tex]\cos^2(\theta_1) = 1 -(\frac{17}{20})^2[/tex]

[tex]\cos^2(\theta_1) = 1 -\frac{289}{400}[/tex]

Take LCM and solve

[tex]\cos^2(\theta_1) = \frac{400 -289}{400}[/tex]

[tex]\cos^2(\theta_1) = \frac{111}{400}[/tex]

Take square roots

[tex]\cos(\theta_1) = \frac{\sqrt{111}}{\sqrt{400}}[/tex]

[tex]\cos(\theta_1) = \frac{\sqrt{111}}{20}[/tex]

equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2,

so in first box - h

in second box - k

after equal to box = r²

Answer:

The answers that would be put into the question box's are: 3, 2, and 16:

(x - 3)^2 + (y - 2)^2 = 16 :)

Hope this helps

Step-by-step explanation:

what you typed in here must be wrong or incomplete.

what you typed is (with explicit multiplication symbols to make it clear)

10×x×2×y - 2

for x=-1 and y=-2

that shows then

10×-1 × 2×-2 - 2 = -10 × -4 - 2 = 40 - 2 = 38

but 38 is not in the answer options.

so, there must be something wrong with your problem description.

Answer:

- 3.21

Step-by-step explanation:

Answer:

radius = 19 ft

Step-by-step explanation:

volume of a cylinder: r²πh

12468.94 = r²π × 11

=> r² = 12468.94 ÷ 11π

=> r² = 361

=> r = 19

Answer:

r=19

Step-by-step explanation:

[tex]12468.94 = (3.14) {r}^{2} (11) \\ \frac{12468.94}{34.54} = \frac{34.54 {r}^{2} }{34.54} \\ \sqrt{361} = \sqrt{ {r}^{2} } \\ 19 = r[/tex]
