Step-by-step explanation:

Answer:

Michael has 3 times more oranges than apples.

Step-by-step explanation:

Given that:

Number of apples = 06

Number of oranges = 18

Let,

x be the number of times.

Number of oranges = Number of times * Number of apples

18 = x * 6

18 = 6x

6x = 18

Dividing both sides by 6

[tex]\frac{6x}{6}=\frac{18}{6}\\x=3[/tex]

Hence,

Michael has 3 times more oranges than apples.

Answer:

21

Step-by-step explanation:

The units Lily walked are 21 units.

Distance is defined to be the magnitude or size of displacement between two positions.

Given that, Lily used a coordinate plane to graph the path she walked from her house to the library. She started at her house at point A(–6, –3), walked to a store at point B(5, –3), and then walked to the library at point C(5, 7).

We know that, the distance between the two points is given by =

D = [tex]\sqrt{(x_{2}-x_{1} )^2 +(y_{2} -y_{1})^2 }[/tex]

The given points are A (–6, –3), B (5, –3) and C (5, 7).

The distance between her house and the store (AB) =

[tex]\sqrt{(5+6)^2 +(-3+3)^2} \\= \sqrt{121} \\= 11[/tex]

Therefore, The distance between her house and the store (AB) = 11 units

Similarly,

The distance between the store and the library (BC) =

[tex]\sqrt{(5-5)^2+(7+3)^2} \\= \sqrt{100} \\= 10[/tex]

Therefore, The distance between the store and the library (BC) = 10 units

Therefore, the total distance = 10+11 = 21 units

Hence, She walked a total 21 units from point A to C.

Answer:

2t-6

Step-by-step explanation:

Answer: The correct option is the first one.

Step-by-step explanation:

Let's define how to interpret each symbol:

x < a  (x is strictly smaller than a, we graph this with an open circle at a, and an arrow to the left of a)

x > a (x is strictly larger than a, we graph this with an open circle at a, and an arrow to the right of a)

x ≥ a (x is larger than or equal to a, we graph this with a closed circle at a, and an arrow to the right of a)

x ≤ a (x is smaller than or equal to a, we graph this with a closed circle at a, and an arrow to the left of a)

In this case, we have the inequality:

x ≤ 15

Then to graph this we need a closed circle at 15, and an arrow to the left. The correct option is the first one.

So since they initially drank 50 gallons, half of that is 25 gallons. 50+25= 75, therefore they drank 75 gallons.

Jada has 12 library books and 1/3 of that is 4, because 12 divided by 3 is 4, so 12-4=8. That means Han checked out only 8 books.

Shape: Isosceles Right Triangle.

Isosceles Right Triangles always have two sides of equal length. In this case, the sides of equal length include 17 and 17. The third side (9) would refer to the base, so it would not count.

Also, if you turn the shape sideways, you can see that the unknown side would be 17.

Answer:

Diameter= 16 cm circumference is 50.24

Step-by-step explanation:

The diameter and the circumference of the circle should be 16 cm and 50.24 respectively.

Since the radius is 8 cm

So here the diameter be

= 2(radius)

= 2 (8)

= 16 cm

Now the circumference of the circle is

[tex]= 2\pi r\\\\= 2 \times 3.14 \times 8[/tex]

= 50.24

hence, The diameter and the circumference of the circle should be 16 cm and 50.24 respectively.

The multiplication of the given numbers is obtained as 0.43.

A number can be rounded to a certain place by looking at the number just after that place. If it is greater than or equal to 5, one is added otherwise it is kept as the same.

The given numbers are 1.34 and 0.32 respectively.

The multiplication of these numbers are given as follows,

1.34 × 0.32

= 0.4288

In order to round it to the nearest hundredth, look at the digit at the thousandth place.

Here, it is given as 8 which is greater than 5.

Thus, the required number is 0.43.

Hence, the required number obtained after the rounding to the nearest hundredth is given as 0.43.

Step-by-step explanation:

Becuase i just did it

The comparison situation is:

Bella save more per chore than Sweet T.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.  LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have,

Bella's amount: d= 3.5c + 11

Sweet T amount:

Rate of Change = (14-12)/ (2-1)= 2

So, d = 2c + 12

Thus, the initial saving of Bella is less than Sweet T and Bella save more per chore than Sweet T.

Answer:

A. $ 46

B. 12 people.

Step-by-step explanation:

From the question given above, we obtained the following:

C(x) = 6.5x + 20

Where:

C => total cost of bowling

x => number of people

A. Determination of the of bowling for 4 people.

Number of people (x) = 4

Total cost (C) of bowling =?

C(x) = 6.5x + 20

C(4) = 6.5(4) + 20

C(4) = 26 + 20

C(4) = $ 46

Thus, it will cost $ 46 for 4 people to bowl

B. Determination of the number of people that can bowl for $ 98.

Total cost (C) of bowling = $ 98

Number of people (x) =?

C(x) = 6.5x + 20

98 = 6.5x + 20

Collect like terms

98 – 20 = 6.5x

78 = 6.5x

Divide both side by 6.5

x = 78 / 6.5

x = 12

Thus, 12 people can bowl for $ 98.
