D. One square and four triangles

Step-by-step explanation:

Cece is finding the surface area of a square pyramid by finding the sum of the areas of its faces

Square pyramid has a square base.

each edge of the square base joins at the top of the vertex to make a pyramid

The sides of the pyramid is a triangle

the square has 4 sides, so four triangle on the sides of the pyramid

Hence one square and four triangles forms a square pyramid

Answer:

The answer is A). one square and three triangles

Answer:

Need the other part of the problem

Step-by-step explanation:

Maybe...2(4+6)=2(10)

1/2 Square equals to 1/4 equals to x over 5 2 Square

therefore 1/4 equals to x over 5 2 square

Equals to 1/4 equals to x over 5 * 4 you know that 2 square equals to 4

So now I'm going to solve for 1/4 equals to x of over 5 * 4 equals to 20

1/4 equals to x over 20

1/4 equals to 20 cross multiply

= 1\4 = x/20

= 4 * x = 20*1

4x = 20

divide both side by the coefficient of x

4x/4 = 20/4

x =5

Answer:

y = - x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

4x + 4y = - 32 ( subtract 4x from both sides )

4y = - 4x - 32 ( divide all terms by 4 )

y = - x - 8 ← in slope- intercept form

Answer:

x+y=-8

Step-by-step explanation:

-32=4x+4y

-4y=4x+32

y=(4x+32)/-4

y=-x-8

x+y=-8

Now comparing to slope intercept form

y=mx+c,we get

slope =1

y intercept =1

y=-8

Answer:

KL = 27

JK = 16

MK = 30

NL = 23

m∠JKL = 132°

m∠KLJ = 22°

m∠KMJ = 54°

m∠KJL = 26°

Step-by-step explanation:

The given parameters of the quadrilateral JKLM are;

JM = 27, ML = 16, JL = 46, NK = 15, KLM = 48, JKM = 78, MJL = 22

Taking the sides as parallel, we have that quadrilateral JKLM is a parallelogram

Therefore;

KL = JM = 27

JK = ML = 16

m∠KLJ = m∠MJL = 22°

MN = NK = 15

MK = MN + NK = 15 + 15 = 30

NL = JL/2 = 46/2 = 23

m∠KJM = m∠KLM = 48°

m∠KJL = m∠KLM - m∠MJL = 48° - 22° = 26°

m∠KML = m∠JKM = 78°

m∠MKL = 180° - m∠KML - m∠KLM = 180° - 78° - 48° = 54°

m∠MKL = 54°

m∠JKL = m∠JKM + m∠MKL = 78° + 54° = 132°

m∠KMJ = m∠MKL = 54°

Applying the properties of a parallelogram, the missing values are:

KL = 27; JK = 16; MK = 30; NL = 23

m∠JKL = 132°; m∠KLJ = 22°; m∠KMJ = 54°; m∠KJL = 26°

Applying the properties of a parallelogram, we will find the given measures as follows:

KL = JM  (congruent sides)

KL = 27

JK = ML (congruent sides)

JK = 16

MK = 2(NK)

Substitute

MK = 2(15)

MK = 30

NL = 1/2(JL)

NL = 1/2(46)

NL = 23

m∠JKL = 180 - m∠KLM (supplementary angles)

m∠JKL = 180 - 48

m∠JKL = 132°

m∠KLJ = m∠MJL (congruent angles)

m∠KLJ = 22°

m∠KMJ = m∠MKL (congruent angles)

m∠MKL = 180° - 78° - 48° = 54°

m∠KMJ = m∠MKL = 54°

m∠KMJ = 54°

m∠KJL = 48° - 22°

m∠KJL = 26°

Answer:

$6000

Step-by-step explanation:

accumulated amount = A = PI

A = $6900

Let P = x

6900 - I = x

I = (x)(0.05)(3yrs) = 0.15x

6900 - 0.15x = x

Add

6900 = 1.15x

Divide, solve for x

Answer:

4metres

Step-by-step explanation:

Given the height of the trail modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers

The horizontal distance occurs at the x intercept i.e at h(x) = 0

Substitute

0 = -0.1x^2 - 0.3x +2.8 ,

Multiply through by -10

0 = x^2 + 3x - 28

x^2 + 3x - 28 = 0

Factorize

x^2 + 7x - 4x - 28 = 0

x(x+7) - 4 (x+7) = 0

(x-4)(x+7) = 0

x-4 = 0 and x+7 = 0

x = 4 and -7

Since the danced cannot be negative, hence the horizontal distance of the trail is 4m

Answer: $48.06

Step-by-step explanation:

Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage. For example, if your product costs $50 to make and the selling price is $75, then the markup percentage would be 50%: ( $75 – $50) / $50 = . 50 x 100 = 50%.

Answer:

h(x) = - (x + 5)³

Step-by-step explanation:

From the graph attached,

Function 'h' is the transformed form of function 'g',

If function 'g' is shifted by k units to the left, the new function 'h' will be,

h(x) = g(x + k)

As shown in the graph,

Function 'g' has been shifted by 6 units to the left,

h(x) = g(x + 6)

h(x) = - [(x + 6) - 1]³

h(x) = - (x + 5)³

Step-by-step explanation:

Use the distributive property.

3(6 + x) = 24

18 + 3x = 24

3x = 6

x = 2

Answer:

x=2

Step-by-step explanation:

3(6+x)=24

Divide both sides by 3.

6+x=24/3

Divide 24 by 3 to get 8.

6+x=8

Subtract 6 from both sides.

x=8−6

Subtract 6 from 8 to get 2.

Answer:

Hi, let's turn the word problem into a set of equations:

Let's say that x = # of chickens, and y = # of pigs

If there are 13 animals altogether, that means that

x + y = 13

If there are 40 legs together, we know that chickens have 2 legs, while pigs have 4, so the total number of legs would be:

2x + 4y = 40

We now have two different equations, with the same two variables, so we can rearrange and substitute one equation into the other to solve. We can rearrange the first equation as:

x + y = 13

x = 13 - y

Let's plug this expression for "x" into the second equation:

2(13-y) + 4y = 40

Now we have an equation with only one variable, so we can use algebra to solve for y:

26 - 2y + 4y = 40

2y = 14

y = 7, there must be 7 pigs.

From the first equation that we rearranged,

x = 13 - y

Now that we know the numerical value of "y", we can plug that in:

x = 13 - 7

x = 6, there must be 6 chickens
