Dale just bought 9 bags of 13 cookies each. He already had 6 cookies in a jar. How many cookies does Dale have now?
Answers
Answer:
123
Step-by-step explanation:
1 bag = 13 cookies
9 bags x 13 cookies = 117 cookies
117 cookies + 6 cookies that he already has = 123 cookies
Dale have 123 cookies in total.
Answer:
123 cookies.
Step-by-step explanation:
Multiply the amount of bags of cookies he bought, and the amount of cookies in each back to find out the amount of cookies he bought all together.
9 x 13 = 117
He already had six cookies saved. Add that the amount he had bought
117 + 6 = 123
Dale has 123 cookies in total.

for the given function the value of the x will be 9.
What is Linear function?A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.
Given a condition, Seven less than four times a number is 29
Let "x" be the number in the equation
Thus,
4*x - 7 = 29
4x = 36
x = 9
therefore, the value of x will be 9 for the given function.

work out the equation of the line which has a gradient of 2 and passes through the point (1,4).
Answers
Answer:
y = 2x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (1, 4) into the partial equation
4 = 2 + c ⇒ c = 4 - 2 = 2
y = 2x + 2 ← equation of line

Amount won = 590
X : ____ 590 ___ 0
P(X) : __ 1/50 __ 49/50
Expected payoff :

Answers
Answer:
514 m = width of the river to the nearest meter
Step-by-step explanation:
You must memorize the definitions of the trig functions and then these types of problems are easy.
You have a right triangle where the 100 m is the adjacent side to the 79° angle. You are looking for the side opposite the 79° angle. So, you need to use the tan function which is defined as opposite side/adjacent side
Let x = the length of the opposite side (width of river)
Tan 79 = x/100
100 tan 79 = x
x = 514 m = width of the river to the nearest meter
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The width of the river is 514.455 meters.
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
Base is the adjacent smaller side of the angle θ.
As it is given that you walk 100 meters to the right of the stake and measure a 79° angle between the stake and the boulder. Therefore, using the tangent angle the width of the river can be written as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\\rm tan(79^o) = \dfrac{\text{Width of the river}}{100\ meter}\\\\\\\text{Width of the river} = tan(79^o) \times 100 = 514.455\ meters[/tex]
Hence, the width of the river is 514.455 meters.

Answers
Answer:
36
Step-by-step explanation:
Give the vertices of a polygon as (7, −18) and (7, 18) .
Length of the side is calculated using the formula;
L = √(x2-x1)²+(y2-y1)²
L = √(7-7)²+(18-(-18))²
L = √0+(36)²
L = √(36)²
L = 36

You can slit it into two rectangles. On rectangle would have a area of 2x6 and another rectangle could have an area of 6x3. then you solve the area of the rectangles and add them for the total area. I have a picture of it:
Answer:
30 square feet
Step-by-step explanation:
1. Approach
Break up the given figure into two smaller rectangles. Calculate the area of those two rectangles, and then add up the results.
2. Rectangle 1
The is one extend the line with the measurement of (4ft), then one will get a rectangle with the dimensions of (6ft) and (3ft). Use the formula,
[tex]length * height = area[/tex]
Substitute;
6 * 3 = 18
3. Rectangle 2
The other rectangle that will result from this partitioning will have the dimensions (2ft) and (6ft). Again use the formula,
[tex]length * height = area[/tex]
Substitute,
2 * 6 = 12
3. Find the total area
Add up the area of these two smaller rectangles,
rectangle1 + rectangle2
= 18 + 12
= 30
