Write the equation of a line through the point (5,4) that is perpendicular to the line y=-5/3x-2
Answer:
y=3/5x+1 because when a line is perpendicular to another line the slope it the opposite meaning negative to positive or positive to negative
you also reverse the number/ fraction...for example, if the slope was 2 the slope in the other equation would be -1/2. if the slope in the first equation was 1/2 the second equation slope would be -2 since it is the opposite and flipped

Marion bought 14 packages of plastic frog and lizard fishing lures. She bought frog lures in
packages of 4 and lizard lures in packages of 6 for a total of 72 lures. How many of each lure did
Marion buy?
A. 6 lizards and 4 frogs
B. 4 lizards and 8 frogs
C. 48 lizards and 24 frogs
D. 24 lizards and 48 frogs
Answer:
C. 48 lizards and 24 frogs
Step-by-step explanation:
Let F = number of frog lures, and let L = number of lizard lures.
Marion bought 14 packages of plastic frog and lizard fishing lures.
She bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures.
F + L = 72
F/4 + L/6 = 14
12 * F/4 + 12 * L/6 = 12 * 14
3F + 2L = 168
(+) -3F - 3L = -216
------------------------------
-L = -48
L = 48
F + L = 72
F + 48 = 72
F = 24
Answer: C. 48 lizards and 24 frogs

A bakery sells cupcakes for $4.45. They have a special sale on St. Patrick's Day and all cupcakes are 42% off. How much would you pay for a cupcake? Show your work.
remember,show your work
want a brainlist and a thanks:
1-answer the question correctly
2-explain it correctly
3-make sure the explanation is understandable
Answer:
$2.58
Step-by-step explanation:
4.45*0.42 = 1.87
4.45 - 1.87 = 2.58
When you multiply things under 0, but still positive, you get the percentage,
for example 0.42 is 42 percent, 0.50 is 50%, and 0.15 is 15%. Which is why you multiply 0.42 by 4.45, you get 1.87.
4.45 minus 1.87 because,
You have 42% of 4.45, but you need to take 42% off.
What is the value of the numerical expression below? -\frac{2}{5}\ \div\left(\frac{8}{7}\times\frac{-7}{8}\right)\ \div-1− 5 2 ÷( 7 8 × 8 −7 ) ÷−1 Show your work. A. -1 B. -\frac{2}{5}− 5 2 C. \frac{2}{5} 5 2 D. 1
Given:
The expression is
[tex]-\dfrac{2}{5}\ \div\left(\dfrac{8}{7}\times\dfrac{-7}{8}\right)\ \div-1[/tex]
To find:
The numerical value of the given expression.
Solution:
We have,
[tex]-\dfrac{2}{5}\div\left(\dfrac{8}{7}\times\dfrac{-7}{8}\right)\ \div-1[/tex]
On simplification, we get
[tex]=-\dfrac{2}{5}\div\left(-1\right)\ \div-1[/tex]
[tex]=-\dfrac{2}{5}\div \dfrac{-1}{-1}[/tex]
[tex]=-\dfrac{2}{5}\div 1[/tex]
[tex]=-\dfrac{2}{5}[/tex] [tex][\because a\div 1=a][/tex]
Therefore, the numerical value of the given expression is [tex]-\dfrac{2}{5}[/tex] and the correct option is B.

What is the measure of arc CD?
A. 124
B. 62
C. 64
D. 60
Help plz!
Answer:
Option D
Step-by-step explanation:
By inscribed angle theorem,
" Measure of an inscribed angle by the arc measures half of the measure of the arc"
m(arc BCD) = 2m(∠BED)
And m(arc BCD) = m(arc BC) + m(arc CD)
m(arc BC) + m(arc CD) = 2m(∠BED)
64° + m(arc CD) = 2(62°)
m(arc CD) = 124 - 64
= 60°
Option D is the answer.

Answer:
y = -7
Step-by-step explanation:
5x+8y=29
5(17)+8y=29 (simplify by multiplying)
85+8y=29 (subtract 85 from both sides)
8y= -56 (divide both sides by 8y)
y = -7
cos B = O.05. what is the approximate measure of angle B
The value of the measure of angle B will be;
⇒ ∠ B = 87.13°
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The value is,
⇒ cos B = 0.05
Now,
Since, The value is,
⇒ cos B = 0.05
Taking cos inverse both side, we get;
⇒ cos⁻¹ cos B = cos⁻¹ 0.05
⇒ B = 87.13°
Thus, The value of angle B = 87.13°

Answer:
C 12.50b+22.50n≥800
Step-by-step explanation:
Tonya is staring a jewelry business. She is going to sell b bracelets for $12.50 each and n necklaces for $22.50. Tonya wants to make at least $800 a month.
When we use the word at least in Mathematics is means that it is equal to or more than $800.
It is represented by the symbol ≥
Number of bracelets = b
Number of necklaces = n
Therefore, the inequality below models this situation is given as:
$12.50 × b + $22.50 × n ≥ $800
= 12.50b + 22.50n ≥ 800
Option C is correct.

Marcus took her client out for dinner that costs $157.75 before taxes. If she paid $7.89 on the meal , calculate the tax rate
Answer:
5%
Step-by-step explanation:
A tax is a compulsory sum levied by the government or an agency of the government on goods and services. Taxes raises the price of products
Tax rate is the percentage a person pays as tax
tax rate = [tex]\frac{tax paid}{cost of the dinner}[/tex] × 100
[tex]\frac{7.89}{157.75}[/tex] × 100 = 5%
She paid a tax rate of 5% on the dinner

Mehvish buys 1/2 kg carrots, 3 kg potatoes, 2 kg onions and 1 1/2kg of chicken.
PRICE LIST
carrots: 50p per kg
potatoes: 64 per kg
onions: 42p per kg
Chicken: £6 per kg
She pays with a £20 note.
Work out the change that Mehvish should get.
Answer:
The amount of change will be £7.99
Step-by-step explanation:
Here, we want to calculate the amount of change that Mehvish should get
1/2 kg carrots at 50 p per kg will be;
1/2 * 50 = 25 p
3 kg potatoes at 64 p per kg will be
3 * 64 = p 192
2 kg onions at 42 p per kg
2 * 42 p = 84 p
1 1/2 kg chicken at £6 per kg will be:
since £1 is 100 p
1.5 * 6 = £9 (9 * 100 p = 900p)
since £1 is 100 p
£20 will be;
20 * 100 = 2,000 p
So let us make the subtraction as follows;
2,000- 900 - 84-192 - 25 = 799 p
In pounds, this is divided by 100
we have this as 799/100 = £7.99
