How do u do this pls someone help me I’ve failed math for 3 quarters straight
Answers
Answer:
1. 84in³
2. 180cm³
3. 600ft³
4. 360cm³
5. 312cm³
6. 15.6kg
7. 1.95kg
Step-by-step explanation:
1: V = Bh = (7x3)x4 = 84in³
2: V = Bh = 1/2(8x5) x 9
= 20 x 9
= 180cm³
3: V = Bh = 1/2(b1+b2) h x 5
= 1/2(20+10) 8 x 5
= 15 x 8 x 5
= 15 x 40
= 600ft³
4: V = Bh = 1/2 (4x9) x 20
= 18 x 20
= 360cm³
5: Total volume = Volume of rectangular prism + Volume of triangular block
= (8.5 x 4 x 9) + 1/2(1.5 x 2) x 4
= 306 + 6
= 312cm³
6: divide 312cm³ by 20kg/cm³ to get the approx. mass:
312/20 = 15.6kg
7: first find the volume of the friends Display:
= (4.25 x 2 x 4.5) + 1/2(0.75 x 1) x 2
= 38.25 + 0.75
= 39cm³
Now divide by 20 to find the approx. weight of the friends display:
39/20 = 1.95kg
Have a nice day! :)

Answer:
The total volume of water in the pool =-2 (x-11)(x+5) ft^3
Step-by-step explanation:
a) (2x^2 + 12x + 10) - (4x^2-100)
= 2x^2+12x+10-4x^2+100
= -2x^2+12x+110
b)
Lets simplify first by taking the GCF out:
= -2 (x^2-6x-55)
Now Just simplify by finding the product of a and c
I used -11 and 5 because when you multiply -11x5 you get -55, and when you do -11+5 you get -6.
= -2 (x-11)(x+5) ft^3
Answer:
Given expressions
Deep end: [tex]2x^2+12x+10[/tex]
Shallow end: [tex]4x^2-100[/tex]
a) Difference between the deep end and shallow end
⇒ difference = deep end - shallow end
[tex]=(2x^2+12x+10)-(4x^2-100)[/tex]
b) simplifying:
[tex]=2x^2+12x+10-4x^2+100[/tex]

The ordered pairs in the table lie in the graph of the linear function whose equation is
y = 3x + 2.
Which ordered pair does not lie on the graph of this function?
A. (10, 32)
B. (8, 13)
C. (–5, –13)
D. (–8, –22)
Answers
Answer:
b
Step-by-step explanation:
Hi ok heres how I got it:
If the equation is y=3x+2, we just need to plug in each x and y value and see which one doesn't work. Either that, or we can just locate it on the graph.
For example,
10,32
Plugging it in gives us:
32=3(10)+2.
This is correct, meaning that A is NOT the answer.
Continuing testing, and we will find that B is the incorrect pair.
13=3(8)+2 is NOT correct.
13=24 is not equal.
Also,
-13=3(-5)+2 CORRECT,
-22=3(-8)+2 CORRECT AS WELL
Answer:
The ordered pair does not lie on the graph of this function is B. (8, 13)
Step-by-step explanation:
=> y = 3x + 2...i)
By putting the value of x in equation i).. from the options
firstly, putting the value of x = 10
=> y = 3(10)+2
=> y = 32
so, its the ordered pair that lie on the graph
now , putting the value of x= 8
=> y = 3(8) +2
=> y = 24 +2
=> y = 26
its 26, so the ordered pair does not lie on the graph of this function is B. (8, 13)

Erica tiene *al menos* 50 libros,su mamá le regala un mueble para acomodar los libros,se coloca 11 libros en cada estantería le sobran 8 y si coloca 9 le sobran 4
Determine la cantidad de estantes y de libros que tiene erica
y de qué forma puede acomodarlo para que no sobre ninguno
Answers
Erica tiene 85 libros y 9 estanterias, para colocar todos los libros sin que le sobre ninguno, puede colocar 17 libros en 5 estanterias.
¿Cuantos libros tiene?
Primero sabemos que Erica tiene, al menos, 50 libros, entonces si definimos L como el numero de libros que tiene, tendremos:
L ≥ 50.
Si coloca 11 en cada estanteria, le sobran 8, entonces podemos escribir:
L = n*11 + 8 (donde n es un número entero).
Si coloca 9, le sobran 4, entonces:
L = k*9 + 4 (donde k es un número entero).
Entonces tenemos que:
n*11 + 8 = k*9 + 4
n*11 - k*9 + 8 - 4 = 0
n*11 - k*9 + 4 = 0
n = (k*9 - 4)/11
Lo que podemos hacer es evaluar k en distintos valors enteros de tal forma que la solucion de n tambien sea entera. Por ejemplo, si k = 2 tendremos:
n = (2*9 - 4)/11 = 14/11
Notar que en este caso n no es entero, asi que no sirve.
Seguimos, si k = 9 tendremos:
n = (9*9 - 4)/11 = 77/11 = 7
Ambos son enteros.
Entonces Erica tiene:
L = 9*9 + 4 = 85 libros en total.
Y el numero de estanterias sera el maximo entre n y k, que es k = 9, hay 9 estanterias.
Para colocarlos sin que le sobren, puede colocar 17 libros en cada estanteria. Asi con 5 estanterias colocara los 85 libros.

Work out the volume of the prism in cm^3 give your answer correct to 3 significant figures
Answers
Answer:
The volume of the prism is 243 cm³
Step-by-step explanation:
The volume of the prism is V = B × H, where
B is the area of its baseH is the height of the prism∵ The prism is a triangular prism
∴ Its base is a triangle
∵ The base of it is a right triangle
∴ Its area B = [tex]\frac{1}{2}[/tex] b h, where b and h are the legs of the right angle
→ We have one leg of the right angle and the hypotenuse, so we
must use the Pythagoras Theorem to find the other leg
∵ (5.4)² + h² = (7.8)²
∴ 29.16 + h² = 60.84
→ subtract 29.16 from oth sides
∴ h² = 31.68
→ Take √ for both sides
∴ h = 5.6284989 cm
→ Now find the area of the base
∵ B = [tex]\frac{1}{2}[/tex] (5.4)(5.6284989)
∴ B = 15.196947 cm²
→ Let us use the rule of the volume above
∵ V = B × H
∵ H = 16 cm
∴ V = 15.196947 × 16
∴ V = 243.151153 cm³
→ Round it to 3 significant figures
∴ V = 243 cm³
∴ The volume of the prism is 243 cm³
