What is the volume of a hemisphere with a diameter of 60.9 in, rounded to the
nearest tenth of a cubic inch?
The volume of the given hemisphere is 59131.7 inches³.
What is a hemisphere?
Hemisphere is the exact one-half of the sphere.
given, diameter of the hemisphere is = d = 60.9 inches
Therefore, radius = d/2 = 60.9/2 inches = 30.45 inches.
Hence, the volume = (2/3) × π × r³ = (2/3) × π × (30.45)³ inches³ = 59131.7 inches³.

Salma and Jared each threw 5 darts at the target shown. Salma scored 19 points by landing 2 darts in A and 3 in B. Jared scored 17 points by landing 1 dart in A and 4 in B. How many points are given for a dart landing in A?
Answer:
5
Step-by-step explanation:
this can be solved using simultaneous equation
2a + 3b = 19 equation 1
1a + 4b = 17 equation 2
Multiply equation 2 by 2
2a + 8b = 34 equation 3
Subtract equation 1 from 3
5b = 15
b = 3
Substitute for b in equation 1
2a + 3(3) = 19
2a = 9 = 19
2a = 10
a = 5
Answer:
Step-by-step explanation:
2a + 3b = 19 equation 1
1a + 4b = 17 equation 2

Subtract equation 1 from 3

Step-by-step explanation:
[-1, 0] times [0, -3, 5]
[0, -1] [0, 1, 2]
hopefully this makes sense.
The rotated triangle by 180° counterclockwise about the origin is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]
How to rotate the triangle?The coordinates of the triangle are given as:
[tex]\left[\begin{array}{ccc}0&-3&5\\0&1&2\end{array}\right][/tex]
The rotation is given as:
180° counterclockwise about the origin.
The rule of 180° counterclockwise about the origin is:
(x,y) ⇒ (-x,-y)
Using the above rule, we have:
[tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]
Hence, the rotated triangle is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

Answer:
DannyStep-by-step explanation:
Danny's speed is given:
15 mphAndrew's speed is found from the table.
Since its the direct relationship, we find it using one pair of values:
Speed = miles/times = 21.75/1.5 = 14.5 mphDanny is faster as 15 mph > 14.5 mph
Speed =Distance/Time
Here speed is equal to slope of box

The sum of the numbers 13 + 13 + 13 is 39.
What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Given expression is,
13 + 13 + 13
Here 13 is added to itself three times.
When 13 added to 13, we get 13 + 13 = 26
Again if we add the number 13 to 26, we get 13 + 26 = 39
13 + 13 + 13
= 26 + 13
= 39
This can also be written in the form of multiplication as 3 × 13, which is also equal to 39.
Hence the number 13 added to itself three times gives 39.

You and your friend each have a canvas of the same size. You divide your canvas into 5 sections and paint 3 of them. Your friend divides her canvas into 7 sections and paints 4 of them. Who paints more?
The person who paints more is given by the inequality equation 3/5 > 4/7
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the number of canvas be 35 ( LCM of 5 and 7 )
Now , when you divide 35 into 5 sections and paints 3 of them ,
The fraction A = 3/5
And , when your friend divide 35 into 7 sections and paints 4 of them
The fraction B = 4/7
And , the inequality equation is A > B
Substituting the values in the equation , we get
3/5 > 4/7
Hence , the one who paints more is you with 3/5 of the canvas

A function f(x) has x-intercepts of -3 and -5. What is the constant term in the function?
f(x) = x2 + 8x +
Answer:
15
Step-by-step explanation:
The x-intercepts -3 and -5 are also "roots" of the polynomial. The corresponding factors are (x + 3) and (x + 5). Multiply the constants together: 3*5 = 15. This is the desired constant term.
Note that your f(x) = x2 + 8x + should be written f(x) = x^2 + 8x + ... The " ^ " denotes exponentiation.
Check: Multiply (x + 3) and (x + 5) together and compare the result to the given polynomial with constant term 15:
f(x) = (x + 3)(x + 5) = x^2 + 3x + 5x + 15 = x^2 + 8x + 15. This matches!
