Stella bought 6 packages of balloons. Each package has 15 balloons in it.
Which TWO number sentences could be used to find the total number of balloons Stella bought?
Answers:
(6×10)+(6×5)
6×10+56
(3×10)+(6×5)
(15×3)+(15×3)
6+15
Answers
Answer:
"Choices A & D": (6 x 10) + (6 x 5). & (15 x 3) + (15 x 3) are the correct number sentences.
Step-by-step explanation:
1. How many balloons are there in total?The total amount of balloons can be found via cross-multiplication. To cross-multiply fractions, we multiply the numerator of the first fraction with the denominator of the second fraction and the numerator of the second fraction with the denominator of the first fraction.If one package has 15 balloons, how many balloons do 6 packages have?:[tex]\frac{1 package}{6 packages} = \frac{15 balloons}{X balloons}[/tex][tex]\frac{1 package xX balloons}{1 package} = \frac{6 packages x 15 balloons}{1 package}[/tex][tex]6 x 15 balloons = 90 balloons.[/tex]So now we know there are 90 balloons in 6 packages. 2. PEMDASPEMDAS states to complete the operations on numbers in the order that the letters appear.1. Parentheses, ie. (6 + 10) - (11 x 5).
2. Exponents, ie. [tex]a^{c}[/tex].
3. Division, ie. 11÷5.
4. Addition, ie. 12+1.
5. Subtraction, ie. 10-5.
3. Find the TWO NUMBER SENTENCES that can be evaluated to 90.Number Sentences:
a. (6 x 10) + (6 x 5).
According to PEMDAS. We multiply the numbers inside the parentheses first.ii. 6 x 10 = 60.
iii. 6 x 5 = 30.
iv. Then we add the products.
v. 60 + 30 = 90.
vi. So this choice IS CORRECT.
b. 6 x 10 + 5.
According to PEMDAS. We multiply first.ii. 6 x 10 = 60.
iii. Then we add the product to 5.
iv. 60 + 5 = 65.
v. 65 DOES NOT equal 90 so this is one of the incorrect number sentences.
c. (3 x 10) + (6 x 5).
According to PEMDAS. We multiply the numbers inside the parentheses first.ii. 3 x 10 = 30.
iii. 6 x 5 = 30.
iv. Then we add the products.
v. 30 + 30 = 60.
vi. 60 DOES NOT equal 90 so this is one of the incorrect number sentences.
d. (15 x 3) + (15 x 3).
According to PEMDAS. We multiply the numbers inside the parentheses first.ii. 15 x 3 = 45.
iii. 15 x 3 = 45.
iv. Then we add the products.
v. 45 + 45 = 90.
vi. So this choice IS CORRECT.
e. 6 + 15.
i. 6 + 15 = 21.
ii.21 DOES NOT equal 90 so this is one of the incorrect number sentences.
4. (6 x 10) + (6 x 5). & (15 x 3) + (15 x 3). These are the correct number sentences.Please let me know if this helped (photo also attached)!!!

Answers
The two cars lying on one side of the plane are 50 meters apart.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
let us assume that the height is 100 m. Let d represent the horizontal distance. For depression of 38°, Ф = 90 - 38 = 52°, hence:
tan(52°) = d / 100
d = 128 m
For depression of 52°, Ф = 90 - 52 = 38°, hence:
tan(38°) = d / 100
d = 78 m
Distance apart = 128 - 78 = 50 m.

There are no solutions for z³ = x³ + y³ for a right triangle
How to determine the true statement?The equation is given as:
z³ = x³ + y³
By Pythagoras theorem, we have:
z² = x² + y²
Multiply both sides by z
z³ = zx² + zy²
By comparing z³ = zx² + zy² and z³ = x³ + y³, we have:
x³ + y³ = zx² + zy²
Factor out z
x³ + y³ = z(x² + y²)
Make z the subject
z = (x³ + y³)/(x² + y²)

Answers
Answer:
center (2, 9); radius 6
Step-by-step explanation:
Standard equation of a circle:
(x - h)² + (y - k)² = r²
where the center is (h, k), and r is the radius.
You have
(x - 2)² + (y - 9)² = 36
(x - 2)² + (y - 9)² = 6²
Compare this last form to
(x - h)² + (y - k)² = r²
h = 2; k = 9; r = 9
Answer: center (2, 9); radius 6
Answer:
centre = (2, 9 ) , radius = 6

(x - 2)² + (y = 9)² = 36 ← is in standard form

What is the net force acting on the crate? 352 n to the left 176 n to the left 528 n to the right 440 n to the right
Answers
The net force acting on the crate is the sum of all the forces acting in the different directions on the crate, which is 176 N to the left.
What is net force?The net force is defined as the sum of all the forces acting on an object.
From the figure given that,
Upward force = 440 N
Downward force = - 440 N
Rightward force = 176 N
Leftward Force = - 352 N
The net vertical force acting on the crate = Upward force + Downward force
= 440 N + (-440 N)
= 0 N
The net horizontal force acting on the crate = Rightward force + Leftward force
=176 N + (- 352 N)
= - 176 N

Answer: B
Step-by-step explanation:
Using the distance formula, we get the height is [tex]4\sqrt{2}[/tex].
Similarly, we get the base is [tex]6\sqrt{2}[/tex].
So, the area is [tex]\frac{1}{2}(4\sqrt{2})(6\sqrt{2})=24[/tex]

Answers
Using it's concept, the probabilities are given as follows:
a) 0.5455 = 54.55%.
b) 0.5909 = 59.09%.
c) 0.4615 = 46.15%.
d) 0.5556 = 55.56%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Item a:
Out of 110 people, 60 prefer sprite, hence the probability is:
p = 60/110 = 0.5455 = 54.55%.
Item b:
Out of 110 people, 65 are between 21 and 40, hence the probability is:
p = 65/110 = 0.5909 = 59.09%.
Item c:
65 people are between 21 and 40, and of those, 30 drink lemonade, hence the probability is:
p = 30/65 = 0.4615 = 46.15%.
Item d:
45 people are under 21 years of age, and of those, 25 drink sprite, hence the probability is:
p = 25/45 = 0.5556 = 55.56%.
