Answer:
y = - 4
Step-by-step explanation:
x = - 1 is the equation of a vertical line parallel to the y- axis
The equation of a line perpendicular to it will therefore be a horizontal line parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (8, - 4 ) with y- coordinate - 4 , then
y = - 4 ← equation of perpendicular line
Divide 1 hour in the ratio 20%to 80%
Answer:
12min 48min
Step-by-step explanation:
1hr=60min
60x20%=12min
60x80%=48min
Answer:
1 : 4
Step-by-step explanation:
20% of 60 mins = 20/100*60 = 12 mins.

If z = -7, what is the value of (-8z) - z?
Answer:
63
Step-by-step explanation:
you will plug in -7 for both z's
(-8(-7) - (-7)
following PEMDAS you will do multiplication first
(-8(-7) = 56
now we have 56 - (-7)
since - and - make a positive it will be
56 + 7 = 63

258 cm PLZ GIVE ME BRAINLIEST
Step-by-step explanation:
Since the chord is given as 80cm, we know from the definition of a chord that it is equidistant to both sides of the circle. Therefore, half the chord is 40. The extension of the center to the chord is perpendicular to the chord(definition of a chord). Therefore, if we connect the center of the circle to the edge of the chord, it's a right triangle. Also the center of the chord is the radius of the circle. Pytharogean theorem: 40^2 + 9^2=r^2 : 1681=r^2: r=41. The radius is 41. Curcumference of circle: pi*2*r : pi*2*41 : pi*82= 258 cm.

How to solve using systems elimination
Answer: x=10; y=-1
Step-by-step explanation:
To solve this via elimination:
get rid of the y's like this:
4x+2y=38 + 2x-2y=22
6x=60
x=10
20-2y=22
y=-1

Rosa want to buy a new TV priced at 499.99 The TV is on sale for 15% off but the cashier informs her that if she applies for a store credit card she can have an additional 10% off. How much will Rosa pay after the discounts and 6% tax have been applied? Write and solve an equation to find the final price.
Answer:
$405,44
Step-by-step explanation:
Equation: 499.99 - (499.99 x 15/100) - 1/10[499.99-(499.99 x 15/100)] + 6/100{1/10[499.99-(499.99 x 15/100) = x
Steps: x = (15 x 499.99)/100 = $74.9985
499.99 - 74.9985 = $424,9915
x = (424,9915 x 10)/100 = $42,49915
424,9915 - 42,49915 = $382,49235
x = $22,949541
382,49235 + 22,949541 = $405,441891
That can be rewritten as $405,44.

Segment MN and Segment PQ intersect at R, as seen in the diagram at the right. Find x, m∠ MRQ, m∠ QRN, m∠ NRP, m∠ PRM.
A) x=10, m
B) x=20, m
C) x=15, m
D) x=18, m
The value of x which is included in terms of both the angles ∠PRM and ∠NRP is given by: Option D: x = 18
What are supplementary angles?Two angels whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
Here, we're specified that:
m∠PRM = measure of angle PRM = (7x -11)°m∠NRP = measure of angle NRP= (4x -7)°They are adjacent and line segments MR and RN are forming a straight line MN, so these angles are supplementary. That means:
(7x -11)° + (4x -7)° = 180°
Opening the brackets, and solving in terms of magnitude, we get:
[tex]7x - 11 + 4x -7 = 180\\11x - 18 = 180\\11x = 180+18 \\\\x = \dfrac{198}{11} = 18[/tex]
Thus, the value of x which is included in terms of both the angles ∠PRM and ∠NRP is given by: Option D: x = 18

You bought an item for $25 on Ebay and plan on marking it up 65%. What price will you sell your item for to the nearest dollar?
Answer:
$41.25
Step-by-step explanation:
The original price is $25. You want to sell it for 65% more. To find this amount, we need to find 65% of 25.
Let's make an equation.
65/100 • 25 = x
Multiply.
x = 16.25
Now we know how much you want to mark it up by.
Add this to your base of $25.
25 + 16.25
= 41.25
You want to sell it for $41.25.
Hope this helps!

A mortgage has an initial balance of $150,000 and is charged 5% yearly interest applied monthly. If a person makes a payment of $1000 each month, which of the following is closest to the mortgage balance after 3 months of payments?
(1) $145,165
(2)$147,520
(3)$148,160
(4)$148,870
A mortgage loan is termed as a loan that is used to purchase or maintain a home, land or other pieces of real estate.
The borrower agrees to repay the amount of loan to the lender over a period of time, usually in a series of regular installments divided into principal and interest. The property is used as security for the loan.
Calculation of the amount of mortgage is as follows:
[tex]\text{Interest}= \text{Mortgage amount} \times\frac{0.05}{12}\times3[/tex] = 1875
[tex]\text{Principal Pay }= 1000 \times3[/tex] = 3000
Total amount paid = Interest + principal pay = 1875 + 3000 = 4875
Initial balance = 150000
The remaining balance for the mortgage amount = initial balance - the total amount paid.
Amount of mortgage = $ 145125.
Therefore the closest to the mortgage balance after 3 months of payments is
(1) $145,165.

Answer:
4 bags will be required.
Step-by-step explanation:
Patio is in the shape of a parallelogram.
Formula for the area of a parallelogram is,
Area = [tex](\text{Base})(\text{Height})[/tex]
= 16.2 × 12
= 194.4 square feet
∵ 50 square feet area is covered by 1 bag of concrete mix.
∴ 1 square feet area will be covered by [tex]\frac{1}{50}[/tex] bag of concrete mix
∴ 194.4 square feet patio will require the concrete mix = [tex]\frac{194.4}{50}[/tex]
= 3.888
≈ 4 bags
Therefore, 4 bags of concrete mix will be required by Dave to add a new patio.

Answer: 55 Square inches
Step-by-step explanation:
You should find the area of the square and rectangle separately
To find the area you multiply length times width, so the area of the square is 4×4 which equals 16
Then you do the same to the rectangle, 13×3=39
To find the area of the whole figure you add the area of the two shapes together 16+39 which should give you 55

Répondre:
AI = 32,36 m
IE = 30,78 m
Explication étape par étape:
Utilisation de Pythagore:
Cosθ = adjacent / hypoténus
AI = hypoténus
θ = 72 °
Adjacent = 10 m
Cos 72 = 10 / AI
0,3090169 = 10 / AI
AI = 10 / 0,3090169
AI = 32,36 m
De la trigonométrie;
IE = opposé
Adjacent = 10m
Tanθ = opposé / adjacent
Tan 72 = IE / 10
IE = Tan 72 * 10
IE = 3,0776835 * 10
IE = 30,78 m
