Answer:
3 million or 3 x 10^6
Step-by-step explanation:
You would round this up to three million because the digit before it is 5 or larger. Then, using the three million number, you move the decimal over 6 places to get a digit less than ten so it would become 3 times 10 to the power of 6

Deal Finder is sorting its production supply of long-sleeve shirts. They have 1,089 long-sleeve shirts. The first 266 are donated, and the rest are split up to be shipped to 3 stores. What fraction represents how many long-sleeve shirts each store will receive? Input your answer as a mixed number. Whats the anwser?
Answer:
274 1/3 long sleeve shirts
Step-by-step explanation:
Deal Finder is sorting its production supply of long-sleeve shirts. They have 1,089 long-sleeve shirts. The first 266 are donated
Hence,
1089 - 266
= 823 long sleeve shirts are left
The rest are split up to be shipped to 3 stores.
This is calculated as:
= 823 long sleeve shirts /3 stores
= 274 1/3 shirts
What fraction represents how many long-sleeve shirts each store will receive?
Each store will receive : 274 1/3 long sleeve shirts
the bottom of a ladder must be placed 10 feet from a building. The ladder is 26 feet. How far above the ground does the ladder touch the wall?
Answer:
The ladder touches the wall at 24 feet from the ground.
Step-by-step explanation:
The wall of the building, the ground, and the ladder form a right triangle, whose longer side is the length of the ladder.
In any right triangle, we can apply Pythagora's theorem to find any missing side length.
The ladder is 26 feet in length, the distance from the bottom of the ladder and the building is 10 feet. Calling H to the distance above the ground where the ladder touches the wall, then:
[tex]26^2=10^2+H^2[/tex]
Calculating:
[tex]676=100+H^2[/tex]
Solving:
[tex]H^2=676-100[/tex]
[tex]H^2=576[/tex]
[tex]H=\sqrt{576}[/tex]
H=24 feet
The ladder touches the wall at 24 feet from the ground.

Use a cofunction identity to rewrite cos(120° − (30° + a)).
Answer:
sina
Step-by-step explanation:
Using the cofunction identity
cos(90 - x) = sinx , then
cos(120 - (30 + a) )
= cos(120 - 30 - a)
= cos(90 - a)
= sina
An expression is defined as a set of numbers, variables, and mathematical operations. Using a cosine function identity cos(120° − (30° + a)) can be written as sin a.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The given cosine expression can be rewritten as,
cos(120° − (30° + a))
Opening the bracket, to simplify the angle,
= cos(120° − 30° − a)
= cos(90° − a)
Since the cosine and sine angles are complementary to each other, therefore, cos(90° − x) = sin(x), thus, we can write the expression as,
= sin a

Deon plots points to show the time it takes him to swim laps on two days. Is there a proportional relationship between the number of laps and minutes? Explain your answer.
Answer:
There's no proportional relationship between number of laps and minutes.
Step-by-step explanation:
The graph given above is a straight line graph, however, it does not cut across the point of origin (0, 0). As a result of this, it would be difficult to get a constant of proportionality, as you'd likely get different constant of proportionality between different points on the line. Thus, the ratio of y and x for each set of points may vary.
So therefore, the relationship between the x and y cannot be proportional.
We can conclude that the graph does not represent a proportional relationship between number of laps and minutes.

(b) Factorise fully.
10x²+6x
Answer:
2x(5x + 3)
Step-by-step explanation:
Factor out common factors. Note that both terms have x inside it. Therefore, you will factor out one x from each term.
Note the factors of both 10 & 6:
10: 1 , 2 , 5, 10
6: 1 , 2 , 3, 6
Note that the greatest factor shared is 2. Divide 2 and x out from both terms:
(10x² + 6x)/2x = 5x + 3
2x(5x + 3) is your answer.

On one play, a football team gained 9 yards. On the next play, the football team received a penalty
of -10 yards.
Answer:
If your asking what the sum of the yards is it would be -1
Step-by-step explanation:
First I would make a number line from -10 to positive 10. Then from zero add nine. Then subtract 10 from 9. Since 10 is bigger than nine it would be a negative number. Hope this helped.

Answer:
f(x) = −2/5x + 1
Step-by-step explanation:
when putting an equation in function notation first you must make sure the equation is in slope-intercept form and then you must rewrite the equation but instead of putting y you will replace it with f(x), or g(x), whichever one you are given directions to put it as.

Estimate √125 to the nearest integer.
Given:
The number is [tex]\sqrt{125}[/tex].
To find:
The estimate value of given number.
Solution:
We have,
[tex]\sqrt{125}=\sqrt{5\times 5\times 5}[/tex]
It can be written as
[tex]\sqrt{125}=5\sqrt{5}[/tex]
We know that, [tex]\sqrt{5}\approx 2.236[/tex]. So,
[tex]\sqrt{125}=5(2.236)[/tex]
[tex]\sqrt{125}=11.18[/tex]
Approx the value to the nearest integer.
[tex]\sqrt{125}\approx 11[/tex]
Therefore, the required integer is 11.
