Answer 1

Answer:

1 cm

Step-by-step explanation:

Sides of the picture added margin:

l = 8 + 2xw = 5 + 2xA(margin) = 30 cm²

Solution:

A(margin) = Total area - A(picture)(8 + 2x)(5 + 2x) - 5*8 = 304x² + 10x + 16x + 40 - 40 - 30 = 04x² + 26x - 30 = 02x² + 13x - 15 = 0x = (-13 + √(13² + 2*4*15))/4x = (-13 + 17)/4 x = 1 cm

Note. The other root is ignored as negative.

3x + y = 8
What is the answer

Answers

Depends on what you are asking
Y = Mx + c
Finding the equation of the line
Which is y = -3x + 8

Or for finding y
Y = 8-3x
Or if u wanna find x

You subtract y from both sides
3x = 8 - y
Dividing both sides by 3
3x/3 = 8/3 -y/3
Which leave 8 -y divided by 3

Answers

Answer:

V = 1250π/3 mm³

V = 1309 mm³

Step-by-step explanation:

The composite figure is made up of a cylinder with radius 5 mm and two hemispheres of radius 5 mm. The height of the cylinder is

20 mm - 5 mm - 5 mm = 10 mm

The two hemispheres make up a full sphere of radius 5 mm.

V = πr²h + (4/3)πr³

V = π(5 mm)²(10 mm) + (4/3)π(5 mm)³

V = [(25 mm²)(10 mm) + (4/3)(125 mm)³]π

V = [250 mm³ + 500/3 mm³]π

V = 1250π/3 mm³

V = 1309 mm³

[tex] \rm\displaystyle (x - 7{)}^{2} + (y + 3{)}^{2} = { 7 }[/tex]

Step-by-step explanation:

QUESTION-1:

we are given the center and the redious of a circle equation

remember that,

[tex] \rm\displaystyle E _{c} :(x - h {)}^{2} + (y - k {)}^{2} = {r}^{2} [/tex]

where (h,k) is the centre coordinate and r is redious of the circle

given that, h=-2 , k=-5 and r=1

Thus substitute:

[tex] \rm\displaystyle (x - ( - 2){)}^{2} + (y - ( - 5) {)}^{2} = {1}^{2} [/tex]

simplify:

[tex] \rm\displaystyle (x + 2{)}^{2} + (y + 5 {)}^{2} = {1}^{} [/tex]

QUESTION-2:

Likewise

[tex] \rm\displaystyle E _{c} :(x - h {)}^{2} + (y - k {)}^{2} = {r}^{2} [/tex]

given that,h=7,k=-3 and r=√7

substitute:

[tex] \rm\displaystyle (x - (7{))}^{2} + (y - ( - 3){)}^{2} = { \sqrt{7} ^{2} }[/tex]

simplify:

[tex] \rm\displaystyle (x - 7{)}^{2} + (y + 3{)}^{2} = { 7 }[/tex]

Answers

Answer:

If it is solving for e then e = -2

Step-by-step explanation:

First you have to add 7 to both sides of the equation. Next you simplify by adding the numbers. Then subtract 7e from both sides of the equation. After that you have to simplify again by combining like terms. Then divide both sides of the equation by the same term which is 2. Finally you have to cancel the terms that are in both the numerator and denominator divide the numbers and you would get -2

We have the given equation:

9e - 7 = 7e - 11

Our goal is to isolate the variable, e.

9e - 7 = 7e - 11

     +7          +7

____________

9e = 7e - 4

-7e  -7e

____________

2e = -4

The volume of Pyramid A is 704 cm3 and the volume of Pyramid B is 297 cm3. If the pyramids are similar and the surface area of Pyramid B is 153 cm2, what is the the surface area of Pyramid A?

Answers

Answer:

272 cm²

Step-by-step explanation:

Step 1

We have to find the scale factor

When given the volume of two solids, the formula for the scale factor is

V1/V2 = (Scale factor)³

The volume of Pyramid A is 704 cm³ and the volume of Pyramid B is 297 cm³

V1 = Pyramid A

V2 = Pyramid B

704/297 = (scale factor)³

We simplify the left hand side to simplest fraction

The greatest common factor of 704 and 297 = 11

704÷11/297÷11 = (scale factor)³

64/27 = (scale factor)³

We cube root both sides

cube root(scale factor)³ = cube root (64/27)

scale factor = (4/3)

Step 2

(Scale factor)² = S1/S2

S1 = Surface area of Pyramid A =?

S2 = Surface area of Pyramid B = 153 cm²

Hence,

(4/3)² = S1/153

16/9 = S1/153

Cross Multiply

S1 × 9 = 16 × 153

S1 = 16 × 153/9

S1 = 272 cm²

Therefore, the Surface Area of Pyramid A = 272 cm²

Grace has $15 in her bank account. She starts

and is saving $10 each week. What is the slope of the line that represents Grace's bank account?

Answers

Answer:

[tex]\frac{5}{1}[/tex] or 5

Step-by-step explanation:

Using the data provided we would create the following equation to calculate Grace's bank account using the variable x to represent the number of weeks.

f(x) = 5x + 15

The slope of a function in such a function would be the value of that is being multiplied by x. The numerator would be the numberof units it is rising in a graph while the denominator represents the number of units it is moving to the right. Since in this scenario, the number is a whole number (5) the denominator is automatically 1. Meaning that the slope is 5 units up for every 1 unit to the right.

Answers

Answer:

Variables : C , S

Equations : C + S = 11

                  3C + 4S = 35

Step-by-step explanation:

Chocolate cookies be = C

Sugar Cookies be = S

Total number of cookies : C + S = 11

Total Spent on the cookies : 3C + 4S = 35

[tex]C + S = 11\\C = 11 - S\\3C + 4S = 35\\3(11 - S ) + 4S = 35\\33 -3S +4S = 35\\-3S + 4S = 35 - 33\\S = 2\\\\C + S = 11\\C + 2 = 11\\C = 9[/tex]

3x+4y=35
x+y=11
x=choc cookies
y=sugar cookies
x+y=11 —> y=11-x
Substitute into other equation:
3x+4y=35
3x+4(11-x)=35
Solve for x
3x+44-4x=35
-x=-9
x=9
Then x+y=11
y=11-x=11-9=2
x=9, y=2
He bought 9 choc cookies and 2 sugar cookies.

At 351 feet tall, the Jefferson Davis Monument in Fairview, Kentucky, is the largest concrete obelisk in the world. Pedro is looking at the top of the monument at an angle of 75 degrees. How far away from the monument is he standing?

Answers

Answer:

The monument is standing at a distance of 834.322 feet

Step-by-step explanation:

Given

Height of the  Jefferson Davis Monument in Fairview = 351 feet

Pedro while looking at the top of the monument makes an angle with the horizontal surface =  75 degrees

As we know  tan θ = Perpendicular / Base

Substituting the given values in above equation, we get -

tan 75 = 351/Base

Base = 351/tan 75

Base = 834. 322 feet
