Answer:
SA = 225 cm²
Step-by-step explanation:
The given pyramid dimensions are;
The length of the rectangular base of the pyramid, l = 12 cm
The width of the base, w = 6 cm
The area of the rectangular base, Aₐ = 12 cm × 6 cm = 72 cm²
The height of one of the triangles forming the side of the pyramid, h₁ = 8 cm
The base length of the above triangle, b₁ = 12 cm
The area of the above triangle, A₁ = (1/2)×12 cm × 8 cm = 48 cm²
The height of the other of the triangles forming the other side of the pyramid, h₂ = 9.5 cm
The base length of the above triangle, b₂ = 6 cm
The area of the above triangle, A = (1/2) × 9.5 cm × 6 cm = 28.5 cm²
The surface area of the pyramid, SA = Aₐ + 2 × A₁ + 2 × A₂
Therefore;
SA = 72 cm² + 2 × 48 cm² + 2 × 28.5 cm² = 225 cm²
SA = 225 cm²

Step-by-step explanation:
Perpendicular : means two lines meet at 90°
1) angle B = 90° - 50°
= 40°
2) Angle D = 90° - 30°
= 70°
¿Qué es un binomio al cuadrado perfecto?
Un binomio al cuadrado es una suma algebraica que se suma por sí misma, es decir, si tenemos el binomio a + b, el cuadrado de ese binomio es (a + b) (a + b) y se expresa como (a + b)2. ... Se le llama cuadrado perfecto, porque el resultado de su raíz cuadrada siempre es un binomio.

Answer:
6 hours
Step-by-step explanation:
Research is 5%, Games is 25%, so the diffrence is 20%
20% of 30 hours = 30 x2/10 = 6 hours
Tremaine played 6 hours more video games than research.
Answer:
F
Step-by-step explanation:
We can use a proportions to solve this problem:
time of researches (in percentages 100% is used to indicate the total)
5 : 100 = x : 30
x = (5 * 30)/ 100 = 1.5
time of games
25 : 100 = x : 30
x = (25 * 30)/100 = 7.5
7.5 - 1.5 = 6 hours
A builder uses the ratio of 3 parts of cement to 12 parts of sand to make a mixture that holds bricks together . How many parts of cement does the builder use for each part of sand ?
Answer:
1/4 parts of cement
Step-by-step explanation:
Given :
3 parts of cement = 12 parts of sand
For each part of sand, let the part of cement used = x
Writing the relation in the form of cross multiplication :
3 = 12
x = 1
Cross multiply :
12x = 3
x = 3 / 12
x = 1/4
Hence, for each part of sand, 1/4 parts of cement is used.

Substitute 3x -4 for y in the equation 7x - 5y = 4.
Step-by-step explanation:
click the photo there is answer
Answer:
see explanation
Step-by-step explanation:
Substituting y = 3x - 4 into the equation gives
7x - 5(3x - 4) = 4 ← distribute and simplify left side
7x - 15x + 20 = 4
- 8x + 20 = 4 ( subtract 20 from both sides )
- 8x = - 16 ( divide both sides by - 8 )
x = 2
Substitute x = 2 into y = 3x - 4
y = 3(2) - 4 = 6 - 4 = 2
WHich of the following has the steepest slope?
a. y = -4x + 1
b. y = 2x + 3
c. y = x+6
d. y = -3x - 4
Answer: Choice A)
y = -4x+1
=======================================
Explanation:
The general format of a linear equation can be written as y = mx+b
m = slope
b = y intercept
The steepest slope is the value of m that is furthest away from zero. If m > 0, then we're looking for the largest value of m or value to the right of 0. If m < 0, then we're trying to get as left as possible.
Of the choices we have, choice A has the m value furthest from 0. If you want, you can make each slope positive and then compare to see which slope is largest.

Solve for r.
0.5(r +2.75) = 3
Answer:
r = 3.25
Step-by-step explanation:
Start by eliminating the decimal fraction 0.5: 2(0.5)(r + 2.75) = 2(3) = 6
Then we have r + 2.75 = 6.
Isolate r by subtracting 2.75 from both sides. This leaves us with
r = 6 - 2.75 = 3.25.
r = 3.25

find f(3) if f(x) = -4x + 1?
Answer:
f (3) equals -11
Step-by-step explanation:
f (x) = -4x + 1
For f(3), just substitute 3 in the place of x:-
f (3) = -4 x 3 + 1
f (3) = -12 + 1
f (3) = -11Answer:
-11
Step-by-step explanation:
where x is out -3 so it would look like
-4(3)+1
which is -11
you do -4 * 3 first which = -12 than add one you will get -11

The graph below shows the relationship between the number of tickets sold for a music concert and the amount of money collected from the sale of the tickets. (1 pt.)
Which equation represents the relationship between the tickets sold (t) and the money collected (c)?
Which equations have no real solution but have two complex solutions? A 3x>2-5=-8 b 2x>2=6x-5 c 12x=9x>2 +4 d -x>2 - 10x =34
Answer:
[tex]3x^2-5x=-8[/tex]
[tex]2x^2=6x-5[/tex]
[tex]-x^2-10x=34[/tex]
Step-by-step explanation:
The equations are:
[tex]3x^2-5x=-8[/tex]
[tex]2x^2=6x-5[/tex]
[tex]12x=9x^2+4[/tex]
[tex]-x^2-10x=34[/tex]
(a) [tex]3x^2-5x=-8[/tex]
Add 8 to both sides
[tex]3x^2 - 5x + 8 =0[/tex]
To do this, we simply calculate the discriminant (d) using:
[tex]d =b^2 - 4ac[/tex]
If [tex]d < 0[/tex]
Then it has complex roots
Where: [tex]a = 3; b = -5; c = 8[/tex]
[tex]d = (-5)^2 - 4 * 3 * 8[/tex]
[tex]d = 25 - 96[/tex]
[tex]d = -71[/tex]
[tex]-71 < 0[/tex] --- complex root
(b) [tex]2x^2=6x-5[/tex]
Equate to 0
[tex]2x^2 - 6x + 5 = 0[/tex]
[tex]d =b^2 - 4ac[/tex]
[tex]d = (-6)^2 - 4 * 2 * 5[/tex]
[tex]d = 36 - 40[/tex]
[tex]d =-4[/tex]
[tex]-4 < 0[/tex] --- complex root
(c) [tex]12x=9x^2+4[/tex]
Equate to 0
[tex]9x^2 - 12x + 4 = 0[/tex]
[tex]d =b^2 - 4ac[/tex]
[tex]d = (-12)^2 - 4 * 9 * 4[/tex]
[tex]d = 144 - 144[/tex]
[tex]d = 0[/tex] ---- real roots
(d) [tex]-x^2-10x=34[/tex]
Equate to 0
[tex]-x^2 - 10x - 34 = 0[/tex]
[tex]d =b^2 - 4ac[/tex]
[tex]d = (-10)^2 - 4 * (-1) * (-34)[/tex]
[tex]d = 100 - 136[/tex]
[tex]d = - 36[/tex]
[tex]-36 < 0[/tex] ---- complex root
The lengths of the sides of a triangle are in the extended ratio 5: 8.9. The perimeter of the triangle is 44 cm. What are the lengths of the sides?
The lengths of the sides of the triangle in cm are
Answer:
10cm, 16 cm, 18 cm
Step-by-step explanation:
We have to find the sum of proportion: sum of ratios =
a : b : c = 5:8:9
Sum of proportion = 5 + 8 + 9
= 22
Length of side a
5/22 × 44 = 10 cm
Length of side b
8/22 × 44 = 16 cm
Length of side a
9/22 × 44 = 18 cm
Therefore: lengths of the sides of the triangle in cm are
10cm, 16 cm, 18 cm

Alex and payton each have a favorite pancake recipe. Alexs recipe uses 7 1/2 cups of flour for 5 batches, paytons recipe uses 3/4s cup of flour more per batch than alexs recipe ises for batch. What expression can be used to determine the number of cups of flour used to make z batches of paytons pancake recipe
Answer:
9/4z cups
Step-by-step explanation:
Alex recipe uses 7 1/2 cups of flour for 5 batches
Cups of flour per batch = 7 1/2 cups ÷ 5 batches
= 15/2 ÷ 5
= 15/2 × 1/5
= (15*1)/(2*5)
= 15/10
Alex recipe per batch= 3/2 cups of flour per batch
paytons recipe uses 3/4 cup of flour more per batch than alexs recipe
Payton's recipe per batch = Alex recipe per batch + 3/4 cups
= 3/2 + 3/4
= (6+3)/4
= 9/4 cups of flour
Payton's recipe per batch = 9/4 cups of flour
What expression can be used to determine the number of cups of flour used to make z batches of paytons pancake recipe
Payton's recipe for z batches = Payton's recipe per batch * number of batches
= 9/4 cups * z batches
= 9/4z cups
Payton's recipe for z batches = 9/4z cups

Explanation:
There are 5 gold and 350 total. That forms the fraction 5/350 which fully reduces to 1/70 after you divide both parts by the GCF = 5
A = 5, B = 350
A/GCF = 5/5 = 1 in the numerator of the final answerB/GCF = 350/5 = 70 in the denominator of the final answerThe fraction 1/70 can be thought of like saying "There's 1 gold coins in 70 coins total" or "there's 1 gold coin for every 70 coins".
Then we could scale up like so
1 gold : 70 total2 gold : 140 total3 gold : 210 total4 gold : 280 total5 gold : 350 totalOn friday a local burger shop sold a combined total of 336 ham burgers and cheese burgers. The number of cheese burgers sold was two times the number of hamburgers sold. How many burgers were sold on friday?

Answer:
The remainder is 7
Step-by-step explanation:
What we have to do here is to set g(x) to zero and solve for x
The value of x is then substituted into the polynomial p(x)
we have this as follows;
x-1 = 0
x = 1
P(1) = 1^3 -6(1)^2 + 9(1) + 3
P(1) = 1 - 6 + 9 + 3
P(1) = 7
This value is the remainder
