Answer:
d
Step-by-step explanation:
A. Between 500 cm and 700 cmB. Between 550 cm and 650 cmC. Between 5.0 cm and 6.0 cmD. Between 5.5 cm and 6.4 cm A B C D
to round off to the nearest cm of 6. the value must be between 5.5 and 6.4
To round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

Answer:
a. x= 9
b. 70
c. 110
d. 70
e. 110
Step-by-step explanation:
a.
congruent angles have the same measure. 1 and 3 are congruent and 2 and 4 are congruent
2(12x+2)+2(7x+7)=360
divide both sides by 2
12x+2+7x+7=180
combine like terms
2+7=9
12x+7x=19x
19x+9=180
subtract both sides by 9
19x=171
divide both sides by 19
x=9
7x+7,
7*9+7
63+7 = 70
1 is 70, 3 is 70
12x+2, x=9
108+2 = 110
2 and 4 is 110
Answer:
Step-by-step explanation:
Angles 1 and 2 are supplementary (their sum is 180 degrees)
7x + 7 + 12x + 2 = 180
19x= 171
x = 9
m 1 = 7 * 9 + 7 = 70 degrees
m 2 = 12 * 9 + 2 = 108 + 2 = 110 degrees
m 3 = angle 1 and angle 3 are vertical, so they have the same measure: 70 degrees.
m 4 = angle 2 and angle 4 have the same measure: 110 degrees

Step-by-step explanation:
We are collecting bananas. Alf has 4 times as many as Jim, and Jim has three times as many as Sid. Altogether they have 192. How many does Sid exactly have?
Answer:
12 bananas
Step-by-step explanation:
We are collecting bananas.
Lets represent, the number of bananas collected by:
Alf = x
Jim = y
Sid = z
Jim has three times as many as Sid.
y = 3z
Alf has 4 times as many as Jim
x = 4y
x = 4 × 3z
x = 12z
Altogether they have 192.
x + y + z = 192..... Equation 1
We substitute
3z for y and 12z fox x in Equation 1
12z + 3z + z = 192
16z = 192
z = 192/16
z = 12
Therefore, since, the number of bananas Sid collected = z
Hence, Sid has 12 bananas exactly

Question-2:the square of x-5 given by
[tex] \displaystyle (x - 5) ^{2} [/tex]
use (a-b)²=a²-2ab+b² to simplify so we obtain:
[tex] \displaystyle {x}^{2} - 10x + 25[/tex]
hence
our answer is 2)
Question-3:to find:
[tex]f(x) - g(x)[/tex]
substitute the value of f(x) and g(x):
[tex] \rm \displaystyle{6x}^{2} + 8x - 5 - ( {2x}^{2} - 4x + 4)[/tex]
remove parentheses and change its sign:
[tex] \rm \displaystyle{6x}^{2} + 8x - 5 - {2x}^{2} + 4x - 4[/tex]
combine like terms:
[tex] \rm \displaystyle{6x}^{2} + 12x - 5 - {2x}^{2} - 4[/tex]
collect like terms:
[tex] \rm \displaystyle{4x}^{2} + 12x -9[/tex]

13.The property used in the product 30 × (-5 × 24) = (30 × -5) × 24 is
Answer:
Associative property of multiplication
Step-by-step explanation:
Associative property of multiplication is one of the properties used to solve mathematical questions
This is given by the formula
a × (b × c) = (a × b) × c
Therefore based on the above explanation, the property used in the product 30 × (-5 × 24) = (30 × -5) × 24 is called the Associative property of multiplication
Factorize: (a+b)^2 + 4 (a+b)+ 4
Stacy invited six friends to her 5th birthday party. How many ways can Stacy's mom arrange the
children around the table for cupcakes and ice cream?
(Answer with no decimals)
Answer:
120 ways
Step-by-step explanation:
Here, we are looking at arranging around a table
To do this, we sit down one of the children and arrange the remaining around the one that we have sat down
In scenario like this, the number of possible arrangement ways will be;
(n-1)! ways
where n is the number of children which is 6 in this case
So the possible number of ways will be;
(6-1)! = 5! = 120 ways

Answer:
f(x) = x³ - 3
Step-by-step explanation:
Given f(x) then the graph of f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < o then a shift down o c units
Here a shift down of 3 units, hence c = - 3, thus
f(x) = x³ - 3

En un triangulo rectangulo,la hipotenusa mide 10 cm y un cateto mide 8 ¿Cual es el valor del otro cateto ?
Respuesta:
6 cm
Explicación paso a paso:
Paso 1: Información provista
Longitud de la hipotenusa (h): 10 cm
Longitud del cateto 1 (c₁): 8 cm
Paso 2: Calcular la longitud del cateto 2 (c₂)
Tenemos un triángulo rectángulo, es decir, que uno de sus ángulos es 90°. Conociendo la hipotenusa y uno de los catetos, podemos determinar la longitud del otro cateto usando el Teorema de Pitágoras.
h² = c₁² + c₂²
c₂² = h² - c₁²
c₂ = √(h² - c₁²)
c₂ = √((10 cm)² - (8 cm)²) = 6 cm

Canada has a population of about 32 million. The population of the United States is 10 times larger. How many people live in the United States? Explain the number of zeros in your answer.
Answer:
People live in the U.S. = 320000000
Step-by-step explanation:
Below is the calculation of a number of people who live in the United States.
Since it is given that the population of the U.S is 10 times larger than Canada's population. So, multiply the Canadas population by 10 in order to get the U.S. population.
Canada population = 32 million or 32000000
Thus the U.S. population = 32000000 x 10 = 320000000

Answer:
4th option 0,5,10,15
Step-by-step explanation:
Let's check if the first choice is geometric.
2*3 = 6. is 6*3 = 18, yes! is 18*3 = 54. Yep! its geometric
the second option multiplies by -2, it is geometric
the third option multiplies by 1/5, it is geometric
The fourth option does not multiply by anything common, it is Not geometric
Answer:
0,5,10,15 is not the sequence of geometric.
Generally, to check whether a given sequence is geometric, one simply checks whether successive entries in the sequence all have the same ratio. The common ratio of a geometric series may be negative, resulting in an alternating sequence.

Elsa uses exactly 60 cubes of ice to build a rectangular ice prism. Each cube has side lengths of 1 unit. Enter the dimensions of the rectangular ice prism below assuming that none of the sides can have a length of 10 units. Your answer should be typed like this with the numbers going from smallest to largest: 1, 2, 3 *
Answer:
2, 5, 6
Step-by-step explanation:
The volume of a rectangular prism is given by [tex]V=l\cdot w\cdot h[/tex], where all variables to the right are dimensions of the prism.
Therefore, we're looking for three numbers that multiply to be 60.
Since the question stipulates that no side length may be 10, we have:
[tex]2\cdot 5\cdot 6=60[/tex]

Please help thank you!
Answer:
10
Step-by-step explanation:
just need number 5 !
Answer:
6.5
Step-by-step explanation:
Cos = Adjacent/Hypotenuse
For the angle with the measure of 70°
Adjacent = x
Hypotenuse = 19
Hence, cos 70 = x/19
multiply both sides by 19
cos(70) * 19 = 19cos(70)
x/19 * 19 = x
we're left with x = 19cos(70)
19cos(70) = 6.5 ( rounded to the nearest tenth )
x = 6.5

A shopkeeper allows 20 % discount on the marked price of an article and 10 % VAT is leavied on it . If a customer pays Rs 5000 for VAT them find the discount amount.
Answer:
Rs 12,500
Step-by-step explanation:
the price before VAT = 100/10 × Rs 5000 =
Rs 50,000
the price before discount = 50,000 / 80%
= 50,000/0.8 = 62,500
so the discount amount = 62,500-50,000
= Rs 12,500
