Your friend finds the persent increase from 18 to 26. Is your friend
correct? Explain your reasoning.
26 - 18
0.31 = 31%
26

Answer:

3.62 grams

Step-by-step explanation:

Multiply  by .4525 to get the answer.

(For percentages you want to move the decimal to the very front. Ex. 2% = 0.02 and multiply by the number you have, in this case 8 grams.)

This should look like this: 0.4525*8=3.62

Answer:

x=4

32x+8= 4

Answer:

Step-by-step explanation:

Since the highest power is x^4, y increases without bound as x approaches positive or negative infinity. So the end behavior is positive infinity.

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

Answer:

4x-8

unless there is a value for x then that is all i can do

hope this helps:)

Answer: 10x - 8

Step-by-step explanation:

(7x - 3) -(5-3x)​

= (7x - 3) - 5 + 3x      Made them without ​parentheses. For -(5-3x), because there are - in front them, which means to multiply -1, so it become -5+3x.

= 7x - 3 - 5 + 3x

= 7x + 3x - 3 - 5

= 10x - 8

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.

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.

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 :)

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,

angleAJF=angleDJI{ vertically opposite angle}

x=76°

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

Answer:

  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

rs10,000

Step-by-step explanation:

Commission = percent commission x worth of the property

0.02 x 500,000 = rs10,000

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.

Answer:

y=0,. X=0.

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
