Answer.

....(
4) (answer with explanation)
Answer:
The cost of one cricket bat is $370, while the cost of one cricket ball is $185.
Step-by-step explanation:
Let's identify what we already know:
1) Mr. Lenny paid a TOTAL of $1480.00 for 4 cricket balls, and two cricket bats.
2) The cost of one cricket bat is twice as much as a cricket ball.
We can create an initial equation:
(4 times x) + (2 times y) = $1480.00
x is the price of one cricket ball, while y is the price of one cricket bat. Considering how the problem is set up, I know the 4 balls should add up to the same price as two bats.
So, the four balls should equal half of $1480, which is $740, and the two bats should also equal $740.
Calculate it out, and you'll find that one cricket bat equals $370, while one ball equals $185.
The question can be solved by representing the cost of a ball as x and bat as 2x, forming the equation 4x + 2(2x) = 1480. Solving this equation finds the cost of the individual cricket ball and bat.
Explanation:In this question, we know that the cost of one cricket bat is twice the cost of a cricket ball, and that Mr. Lenny bought 4 cricket balls and 2 cricket bats for $1480.00. To solve for the individual price of each item, we can use the method of substitution in algebra.
Let's represent the cost of a ball as x and a bat as 2x. This becomes an equation of 4x (cost of 4 balls) + 2(2x) (cost of 2 bats) = 1480.
Solving for x will give us the cost of one cricket ball, and multiplying the value of x by 2 will offer the cost of a single cricket bat.

Julia bought 12 bags of cucumber seeds. each bag contains 42 seeds. if she plant one half of the seeds how many seeds does she have left
Answer:
She will have 252 seeds left.
Step-by-step explanation:
12 x 42 = 504
504 ÷ 2 = 252
So, she will have planted 252 seeds and she will have 252 seeds left to plant.
Final answer:
Julia has 252 seeds left after planting half of the seeds.
Explanation:
To find out how many seeds Julia has left, we first need to determine the total number of seeds she has. Julia bought 12 bags of cucumber seeds, and each bag contains 42 seeds. So the total number of seeds she has is 12 bags × 42 seeds per bag = 504 seeds.
If Julia plants one-half of the seeds, she would be planting 504 seeds × 1/2 = 252 seeds.
To find out how many seeds she has left, we subtract the number of seeds she planted from the total number of seeds she initially had. 504 seeds - 252 seeds = 252 seeds left.
How to work out -31-4x=-5-5(1+5x)
Answer: x = 1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−31−4x=−5−5(1+5x)
−31+−4x=−5+(−5)(1)+(−5)(5x)(Distribute)
−31+−4x=−5+−5+−25x
−4x−31=(−25x)+(−5+−5)(Combine Like Terms)
−4x−31=−25x+−10
−4x−31=−25x−10
Step 2: Add 25x to both sides.
−4x−31+25x=−25x−10+25x
21x−31=−10
Step 3: Add 31 to both sides.
21x−31+31=−10+31
21x=21
Step 4: Divide both sides by 21.
21x/21 divided by 21/21

Answer:
[tex]32,24,18,\frac{27}{2} ,\frac{81}{8}[/tex]
Step-by-step explanation:
Let x, y , and z be the numbers.
Then the geometric sequence is [tex]32,x,y,z,\frac{81}{8}[/tex]
Recall that term of a geometric sequence are generally in the form:
[tex]a,ar,ar^2,ar^3,ar^4[/tex]
This implies that:
a=32 and [tex]ar^4=\frac{81}{8}[/tex]
Substitute a=32 and solve for r.
[tex]32r^3=\frac{81}{8}[/tex]
[tex]r^4=\frac{81}{256}[/tex]
Take the fourth root to get:
[tex]r=\sqrt[4]{\frac{81}{256} }[/tex]
[tex]r=\frac{3}{4}[/tex]
Therefore [tex]x=32*\frac{3}{4} =24[/tex]
[tex]y=24*\frac{3}{4} =18[/tex]
[tex]z=18*\frac{3}{4} =\frac{27}{2}[/tex]

If an intercepted arc measures 124°, what is the measure of its inscribed angle? the same, 124° twice the measure, 248° half the measure, 62°
Answer:
The correct option is C.) half the measure 62°
Step-by-step explanation:
i) Intercepted arc measures 124°
ii) The measure of the inscribed angle will be half of the intercepted arc
therefore inscribed angle = 124° / 2 = 62°
iii) Therefore the correct option is C.) half the measure 62°
The measure of an angle inscribed in a circle is half the measure of its intercepted arc. Therefore, if the intercepted arc is 124°, the inscribed angle would be 62°.
Explanation:This problem is related to the relationship between arcs and inscribed angles in circles. In geometry, there's a specific rule that states: the measure of an angle inscribed in a circle is half the measure of its intercepted arc.
Therefore, if the intercepted arc measures 124°, its inscribed angle would have half the measure, or 62°. If the inscribed angle were to have the same measure, it would imply that the arc measure was double the angle, which is not the case here.

The sides 5, 6, and 12 form a triangle. True or False
Answer:
False
Step-by-step explanation:
According to the The Triangle Inequality Theorem, the sum of any two sides of a triangle must be greater then the measure of the third side. So use this theorem to solve:
6+12=18 and 18>5
so far it is following the theorem but we need to make sure all of the sides follow it so lets continue.
6+5= 11 and 11<12
This does not follow the theorem, so the sides 5,6, and 12 cannot form a triangle.

The area of a rectangle is 54x^9y^8 square yards. If the length of the rectangle is 6x^3y^4 yards, which expression represents the width of the rectangle in yards?
60x^12y^12
9x^3y^2
9x^6y^4
48x^6y^4
Answer:
9 x⁶y⁴
Step-by-step explanation:
for a rectangle
area = length x width, (rearranging)
width = area / length
given area = 54x⁹y⁸ and length = 6x³y⁴
width = 54x⁹y⁸ / 6x³y⁴
= (54/6) ( x⁹y⁸ / x³y⁴)
= 9 ( x⁹y⁸ / x³y⁴)
= 9 ( x⁹⁻³y⁸⁻⁴ )
= 9 ( x⁶y⁴ )
= 9 x⁶y⁴
The expression represents the width of the rectangle in yards is 9 x⁶y⁴.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
For a rectangle
width = area / length
The given area = 54x⁹y⁸ and length = 6x³y⁴
width = 54x⁹y⁸ / 6x³y⁴
= (54/6) ( x⁹y⁸ / x³y⁴)
= 9 ( x⁹y⁸ / x³y⁴)
= 9 ( x⁹⁻³y⁸⁻⁴ )
= 9 ( x⁶y⁴ )
= 9 x⁶y⁴
Hence, the expression represents the width of the rectangle in yards is 9 x⁶y⁴.

The pet store has 20 mice: 11 are white, five are
grey, and four are brown. If the pet storeowner
randomly chooses a mouse for the window
display, what is the probability that the mouse
will be grey?
Answer:
The answer is: 5/20 or a 25% chance
The probability that the pet store owner randomly selects a grey mouse for the window display is 0.25 or 25%.
Explanation:The question asks for the probability of selecting a grey mouse from a pet store that has a total of 20 mice consisting of 11 white, 5 grey, and 4 brown mice. To find the probability, we use the ratio of the number of grey mice to the total number of mice.
The formula for probability is:
Probability (P) = Number of favorable outcomes / Total number of outcomes
We apply the formula as follows:
P(grey mouse) = Number of grey mice / Total number of mice = 5 / 20 = 0.25 or 25%
Therefore, the probability that the pet store owner selects a grey mouse for the window display is 25%.
