Duncan is running to raise awareness and money for cancer. He finds 2 people who have pledged to
donate money based on the distance he runs. His neighbor says he will donate $0.25 for every 40 feet
Duncan runs. His aunt also says that she will donate $12 for every mile he runs. If Duncan runs a total of
7 miles during the cancer awareness run, how much money will he have raised based on these two
donations?
Answer:
$1008
Step-by-step explanation:
12 x 7 = $84 his aunt gives him.
1 mile = 5,280 feet
5,280 x 7 = 36,960 feet he ran.
5,280 ÷ 40 = 132 for every mile he runs
132 x 7 = $924 from his neighbor.
924 + 84 = 1,008

D. h(x) = 5x² +12x +9
Step-by-step explanation:
The final constants are mostly different, so you can simplify your work by just figuring that one.
h(x) = g(x) -f(x)
h(0) = g(0) -f(0) = -7 -(-16) = +9 . . . . . matches choice D
__
If you want to figure the whole expression ...
h(x) = g(x) -f(x)
h(x) = 12x² +7x -7 -(7x² -5x -16)
h(x) = 12x² +7x -7 -7x² +5x +16
h(x) = (12 -7)x² +(7 +5)x +(-7 +16)
h(x) = 5x² +12x +9 . . . . . matches choice D

Someone HELLPPPPPPPPPPPPP
Answer:
I am pretty sure the answer is B.
Answer:
B
Step-by-step explanation:
These are confusing, so I understand why it's a little bit of a frustration lol.
The first thing to look for is where the point is placed. This is -1, so make sure it's not on a positive 1.
All of them are using open circles, so this is such an easier way to tell which one to use. If it did have a closed and open circle for the point, remember that the inequality symbols > and < will always have an open circle. (By open I mean it isn't filled in).
The next thing to look for is to look where the line should be going. I can see that you selected D, but you want x to be less than -1, not greater. If the inequality symbol is turned away it means the number/variable is less than whatever it's being compared to, if that makes sense.
It's almost so simple yet so confusing at the same time. Good luck :)

Area of a triangle is 1/2 x base x height.
Base is given as 14
Height is given as 10
Area = 1/2 x 14 x 10
Area = 70 square meters
Answer:
A = 70 m²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 14 and h = 10 , then
A = [tex]\frac{1}{2}[/tex] × 14 × 10 = 7 × 10 = 70 m²

Answer:
[tex]\Huge\boxed{x=71.9}[/tex]
Step-by-step explanation:
Hello There!
Once again we are going to use trigonometry to solve for x
Here are the Trigonometric Ratios
sin = opposite divided by hypotenuse
cos = adjacent divided by hypotenuse
tan = opposite divided by adjacent
we need to find x and we are given its opposite side length (58) and the adjacent side length (19)
this corresponds with tangent so once again we will be using tangent to solve for x
Looking at tangent we see that its equal to opposite divided by adjacent so we create an equation
[tex]tan(x)=\frac{58}{19}\\\frac{58}{19} =3.052631579[/tex]
now we have
[tex]tan(x)=3.052631579[/tex]
Once again we need to get rid of the tan
to do so we take the inverse of tan ( tan^-1) and apply it to each side
[tex]arcsin^-^1(tan(x))=x\\arcsin^-^1(3.052631579)=71.86191784[/tex]
finally we round to the nearest tenth
we're left with x = 71.9

4. Angie was given a gift card with a $75 balance. She only uses the gift card to purchase her daily cup of chai tea from her favorite café. A cup of tea is $2.85. The equation y = 75 - 2.85x represents the amount of money remaining on the gift card after x cups of tea. a. Identify and interpret the x- and y-intercepts. Round to the nearest tenth, if necessary. b. Predict how many cups of tea Angie has purchased when the gift card balance is about $35.
Answer:
Angie originally has $75 on her card.
She only uses the card for a daily cup of tea of $2.85
Then the equation:
y = $75 - $2.85*x
represents the balance on the card after x cps of tea.
a) The x-intercept is the pair (x, 0), meaning that y = 0, so this is the point at which the balance of the card is zero.
Here we need to solve:
0 = $75 - $2.85*x
$2.85*x = $75
x = $75/$2.85 = 26.3
Here we have a particular case because she can not buy 0.3 of a cup of tea, so the card will never reach a balance of $0.
The y-intercept is the pair (0, y) so we have x = 0, then: y = $75 - $2.85*0 = $75
This is the initial balance of the card.
b) Here we need to solve
y = $35 = $75 - $2.85*x
for x
$35 = $75 - $2.85*x
$35 + $2.85*x = $75
$2.85*x = $75 - $35 = $40
x = $40/$2.85 = 14.03
So after 14 cups of tea, the card's balance will be near $35.
The value of X is .... Each of the two angles in the diagram measures ....

If the diagonals of a quadrilateral are congruent, is the quadrilateral always a rectangle?
Answer:
Yes
Step-by-step explanation:
The only quadrilaterals with congruent diagonals are squares and rectangles and squares are technically rectangles so the answer is yes.
If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.
What is a quadrilateral?The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.
It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
If the diagonals of a quadrilateral are congruent. Then the quadrilateral can be a square or a rectangle.
If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

Step-by-step explanation:
angle HIJ=107°
angle IDJ=31°
now,
angle HIJ+angle JID=180°{ being straight angle}
107+angle JID=180°
angle JID=180°-107=73°
again,
angle JID+angleIDJ+angleDJI=180°{ sum of angle of triangle}
73°+31°+angleDJI=180°
angle DJI=180°-1104°=76°
hence,

- the amount of money hassan receive from selling fruits and vegetables is in the ratio .
fruit: vegetables =9:8
hassan receives total of $5765 from selling fruits and vegetables. how much did he receive from selling fruits and vegetables each.
-hassan sold oranges at $0.35 per kg .if he reduced the price for 40%. what is new price of oranges per kilograms.
- the sale price of oranges $0.35 was increased of 25% from the previous price ,calculate previous day price .
hlp plzzzzzzzzzzzzz
Answer:
950kg
Fruits = 3052.06
vegetables = 2712.94
$0.12
$0.44
Step-by-step explanation:
The first step is to determine the total tonnes of fruits and vegetables sold
7/12 x b = 2.28
b = 2.28 tonnes
Next we determine the tonnes of fruits sold
5/12 x 2.28 = 0.95 tonnes
Next we convert tonnes to kg
1 tonne = 1000kg
0.95 x 1000 = 950 kg
Money he received from selling fruits = 9/17 x $5765 = $3052.06
Money he received from selling vegetables = $5765 - $3052.06 = $2712.94
If price was reduced by 40%, price would be (100-40%) 60% of the original price
0.6 x 0.35 = $0.21
If price was increased by 25%, price would be (100 + 25) 125% of the original price
1.25 x 0.35 = $0.44
In this exercise we have to use the knowledge of finance and percentage to calculate the values of vegetables and fruits:
A)[tex]950\ kg[/tex]
B)Fruits: [tex]\$ 3052.06[/tex] and Vegetables: [tex]\$ 2712.94[/tex]
C)[tex]\$0.12[/tex]
D)[tex]\$0.44[/tex]
The first step is to determine the total tonnes of fruits and vegetables sold:
[tex](7/12)*( b )= 2.28\\b = 2.28\ tonnes[/tex]
Next we determine the tonnes of fruits sold:
[tex](5/12)*( 2.28) = 0.95 \ tonnes[/tex]
Next we convert tonnes to kg:
[tex]1 \ tonne = 1000 \ kg\\(0.95)*( 1000) = 950\ kg[/tex]
Money he received from selling fruits: [tex](9/17)*(5765) = \$3052.06[/tex] Money he received from selling vegetables: [tex]5765 - 3052.06 = \$2712.94[/tex]
If price was reduced by 40%, price would be 60% of the original price, so:
[tex](0.6)*(0.35) = \$0.21[/tex]
If price was increased by 25%, price would be 125% of the original price, will be:
[tex](1.25)*(0.35) = \$0.44[/tex]
