Step-by-step explanation:
Remark
The plan is to find the third side. It and the 9 foot side form a right angle. The base is given as 9 feet. The third sid will be the altitutude. The formula is Area = 1/2 * Base * third side.
Formulas
c^2 = b^2 + a^2
Area = 1/2 b * a
Givens
c = 13 feet
a = ?
b = 9 feet.
Answer: 42.2 square feet.
Solution
c^2 = b^2 + a^2
13^2 = 9^2 + a^2
169 = 81 + a^2 Subtract 81 from both sides.
169 - 81 =81 - 81 + a^2 Combine
88 = a^2 Take the square root of both sides
√a^2=√88
a = 9.381
Area = 1/2 * 9 * 9.381
Area = 42.21
Rounded to the nearest 1/10 Area = 42.2

4 The temperature in Stockton was 83°F. The temperature in New York was –5°F. How much hotter was the temperature in Stockton?
Answer:
It was 88°F hotter in Stockton.
If it was 0°F in New York, Stockton would have been greater by 83°F; as it is -5, add 5 to 83.
As the problem is subtraction, negative.
If the quantity is in negative, like -5, -7, -120; you have to add.

Answer:
140.4ft^2
Step-by-step explanation:
since all four sides are equilateral triangles, you only need to find one triangle and multiply by 4.
area of triangle = 0.5×base×height = 0.5×7.8ft×9ft =35.1ft^2
surface area of pyramid= 35.2ft^2 × 4 = 140.4ft^2

Answer:
there are three ( 3 ) possible outcomes that are 1,2 and 3
Typically, I would say 3. So there's always that. But it could also be 4 because your spinner could land on a line. So I would say either 3 or 4.

measures of the angles related when parallel lines are
cut by a transversal?
Answer:
When two parallel lines are cut by a transversal, four interior angles are formed on the inside of the parallel lines and four exterior angles are formed on the outside of the parallel lines. The angles inside a polygon are called interior angles of the polygon.

Step-by-step explanation:
Using the figure below, find m∠SRT.
Answer:
A. 35°
Step-by-step explanation:
Step 1: Derive an Equation
To answer this question, we will use what's called the Triangle Sum Theorem, which states that the sum of all of the interior angles of a triangle is 180°.
By this theorem, in ΔSRT (the triangle, not the angle), the sum of m∠TSR, m∠RTS, and m∠SRT is 180°. Putting this into a mathematical equation gives us the following:
m∠TSR + m∠RTS + m∠SRT = 180°
Now, from the picture, we can see that m∠TSR = 20° and m∠RTS = 125°. Substituting these values into our original equation gives us:
20° + 125° + m∠SRT = 180°
Step 2: Solve the Equation
Solving for m∠SRT, we get:
20° + 125° + m∠SRT = 180°
145° + m∠SRT = 180° (Simplify the LHS by combining like terms)
m∠SRT = 35° (Subtract 45° from both sides of the equation to isolate m∠SRT)

Simplify using the rules of exponents:
b^4 x (b^2) ^6
A) b^12
B) b^48
C) b^16
D) b^68
Answer:
C
Step-by-step explanation:
Whenever you see a variable with an exponent (in parentheses) with another exponent (outside of the parentheses), you need to multiply them together.
[tex]2 \times 6 = 12[/tex]
Now that we only have b^4 x b^12, you might think we need to multiply the exponents again, but that would be wrong.
The only case where you should be multiplying exponents would be in the case of the first step.
Instead, we need to add them.
[tex] { b}^{4 + 12 = 16} [/tex]
Now we know our answer is C.

Answer:
x = 37°
x = 40°
x = 260°
Step-by-step explanation:
To find angle x when two secants or tangents intersect outside the circle, simply subtract the smaller arc from the bigger arc and half the result.
Question 1
[tex]x=\dfrac12(128^{\circ}-54^{\circ})=37^{\circ}[/tex]
Question 2
To find the bigger arc, subtract the smaller arc from 360°
⇒ 360° - 140° = 220°
[tex]x=\dfrac12(220^{\circ}-140^{\circ})=40^{\circ}[/tex]
Question 3
The smaller arc can also be found by subtracting the external angle from 180°
Smaller arc = 180° - 80° = 100°
[tex]80^{\circ}=\dfrac12(x-100^{\circ})[/tex]
[tex]160^{\circ}=x-100^{\circ}[/tex]
[tex]x=260^{\circ}[/tex]
#1
2x=128-542x=74x=37°#2
Bigger Arc=360-140=220°
2x=(220-140)2x=80x=40°#3

julia and kelsey are both babysitters. julia charges a flat fee of $30 plus $5 per hour. and kelsey charges a flat fee of $10 plus $15 per hour. which system of equations represents the information given? let z represent the number of hours spent babysitting. let y represent the money earned. (answer choices are in the picture)
Answer:
I think it's the 2nd choice. Hopefully I got this correct :)
Step-by-step explanation:
I think you wrote that z will represent the number of hours spent babysitting but I think you meant x.
It's the 2nd choice because $30 is the flat rate for Julia and $10 is the flat rate for Kelsey. Julia has a rate of $5 per hour so that will be the number with the x. And Kelsey has a rate of $15 per hour so that will be the number with the x.
Julia: y = 5x + 30
Kelsey: y = 15x + 10.

There are 6 zeros, so add them to the 1.
The product of given numbers is 1,000,000.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.
We need to find the product of 1000×1000.
Now, 1000×1000
= 1,000,000
Therefore, the product of given numbers is 1,000,000.
