Answer:

50

Step-by-step explanation:

Wen: 30% of the total number of cards = 60 cards

Set this up as an equation

30/100 = 60/x

Cross multiply

30 × x = 100 × 60

30x = 6000

Divide both sides by 30 to isolate the variable

x = 200

There are 200 cards total

Gina: 25% of the total 200 cards

Set this up as an equation

25/100 = x/200

Cross multiply

25 × 200 = 100 × x

5000 = 100x

Divide both sides by 100 to isolate the variable

50 = x

Gina's share is 50 cards

Step-by-step explanation:

(6x+4)+(4x+26)+110°=180°{straight angle}

10x+140=180°

10x=180-140

x=40/4

x=10

(6x+4)=(6×10+4)=(60+4)=64°

(4x+26)=(4×10+26)=40+26=66°

hope it helps.

Answer:

6x+4+4x+26+110=180 straight line

10x=180-140

x=40/10=4

<A=4x+26=4×4+26=42

Answer:

5

Step-by-step explanation:

7^2 = (2(6)^1/2)^2 + BC^2 (Pyth. theorem)

BC = 5

Answer:

its supposed to be 6.08 but we can take of..08 so 6

Step-by-step explanation:

[tex]a + b = c \\ ( 2 \sqrt{6} ) {}^{2} + {b}^{2} = {7}^{2} \\ 2 \times 6 + {b}^{2} = 49 \\ {b}^{2} = 49 - 12 \\ {b }^{2} = 37 \\ \sqrt{b} {}^{2} = \sqrt{37} \\ b = 6.08 \: or \: 6[/tex]

Answer:

b=9

Step-by-step explanation:

1/3b=3

divide 1/3 on each side

b=9

Answer:

Answer below (dont flag people if they dont get it right, that's just messed up).

Step-by-step explanation:

The scale factor is 1.5

Answer:

Step-by-step explanation:

Prime factorization requires dividing by primes starting with smallest prime number

402/2=201

201/3=67, 67 is prime so we cannot go further so the prime factorization of 402 is

2X3X67

Answer:

The answer is "6".

Step-by-step explanation:

Please find the complete question in the attached file.

Given:

[tex]percenatge= 15 \%\\\\beads= 40[/tex]

[tex]\to \frac{15}{100} \times 40\\\\\to \frac{600}{100} \\\\\to 6[/tex]

step 1: plot your points.

step 2: find the rise over run

step 3: place the rise over run in decimal form. say its 5 to the side and 2 up 2/5 (if it was a negative rise such as 2 down it would be -2/5)

step 4= find where it crosses the y line such ex: 0,8 it would be 8 (if it were negative it would be 0,-8: -8)

then put in y intercept form: y=2/5x+8

Answer:

7.5

Step-by-step explanation:

Divide 3 by 2/5

3 divided by 2/5 = 7.5

Answer:

7.5

Step-by-step explanation:

when you do 2/5 it = 0.4 then you do 3/0.4 and you get 7.5

i need points yk, plz give brainliest

Answer:

adjacent angles

Step-by-step explanation:

they dont make a straight line so they arent supplementary. they arent complementary because they dont make a right angle

Answer:

Step-by-step explanation:

CA and CB are both opposite equal 90 degree angles so are equal so we can say

8x-12=4x

4x-12=0

4x=12

x=3, since CA=4x

CA=4(3)=12

Answer:

v= 25

Step-by-step explanation:

Try to isolate the variable by getting rid of the 5. Multiply both sides of the equation by 5 to cancel out the 5 on the left side. You are left with 7v= 35(5). Simplified it is 7v= 175. Then to get the v alone, you need to divide both sides by 7 to cancel out the 7 on the left side. You are left with v= 175/7.

This is v= 25

Answer:

[tex]\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a} \\\\or\\-\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a}[/tex]

Step-by-step explanation:

The quadratic formula for

[tex]ax^2+bx+c=0[/tex]

the solution is: (-b±√(b²-4ac))/(2a)

The solution is:

[tex]\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a} \\\\or\\-\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a}[/tex]

Answer:

15

Step-by-step explanation:

distance formula = square root of difference of y-values subtracted by difference of x-values

d = [tex]\sqrt{144+81}[/tex] = 15

Answer:

Step-by-step explanation:

d^2=dx^2+dy^2

d^2=(-3+12)^2+(15-3)^2

d^2=81+144

d^2=225

d=15

Answer:

You can use grid method.

That is easy.

Answer:

angle UTS +TSU =TUV

THEREFORE, 81 + 12X =24X+9

THEREFORE, 81 - 9 = 24X - 12X

THEREFORE, 72 = 12X

THEREFORE, 72/12 =X

THEREFORE, x = 6

THEREFORE, ANGLE TSU = 12 * X

= 12 *6

= 72

YOUR ANSWER IS

X=6

TSU=72

Answer: 2

Step-by-step explanation:

Let's substitute the number as x in the equation.

Triple means you multiply it by 3.

Then you add four, and get 10.

We can write that like this:

3x + 4 = 10

Then subtract 4 from both sides:

3x = 6

And then divide both sides by 3:

x = 2

So the number is 2.

Answer:

[tex]Average = 30[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4^{x - 1} + 2[/tex]

Required

Average [tex]rate\ of\ change[/tex] from 2 to 4

This is calculated using:

[tex]Average = \frac{f(b) - f(a)}{b - a}[/tex]

Where

[tex]a= 2[/tex]  and  [tex]b = 4[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{4 - 2}[/tex]

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

Calculate f(2) and f(4)

[tex]f(x) = 4^{x - 1} + 2[/tex]

[tex]f(2) = 4^{2-1} + 2[/tex]

[tex]f(2) = 4 + 2[/tex]

[tex]f(2) = 6[/tex]

[tex]f(4) = 4^{4-1} + 2[/tex]

[tex]f(4) = 4^3 + 2[/tex]

[tex]f(4) = 66[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

[tex]Average = \frac{66 - 6}{2}[/tex]

[tex]Average = \frac{60}{2}[/tex]

[tex]Average = 30[/tex]

Answer:

the percentage increase is 5.3%

Step-by-step explanation:

The computation of the percentage increase is shown below:

= (Current year - last year) ÷ (last year)

= (378 euros - 359 euros) ÷ (359 euros)

= 19  euros ÷ 359 euros

= 5.3%

hence, the percentage increase is 5.3%

Answer:

yes, it is a right triangle.

Step-by-step explanation:

you could use the pythagorean theory to check:

[tex]a^{2} + b^{2} = c^{2}[/tex]

(the hypotenuse is the longest side)

[tex]17.5^{2} + 6^{2} = 18.5^{2}[/tex]

[tex]306.25 + 36 = 342.25[/tex]

[tex]342.25 = 342.25[/tex]

Answer:

x=-5 & y=-2

Step-by-step explanation:

Step 1: Solve y=x+3 for y:

y=x+3

Step 2: Substitute x+3 for y  in 3x-4y =-7:

3x-4y=-7

3x-4(x+3)=-7

-x-12=-7 (Simplify both sides of the equation)

-x-12+12=-7+12 (Add 12 to both sides)

-x=5

-x/1=-5/-1 (Divide both sides by -1)

Step 3: Substitute -5  for x in y=x+3:

y=x+3

y=-5+3

y=-2 (Simplify both sides of the equation)

x=-5 and y=-2

Explanation:

We have to assume the triangle is a right triangle.

In a 30°-60°-90° right triangle the side lengths have the ratio ...

  short side : long side = 1 : √3

This lets you write the proportion ...

  x/15 = 1/√3

Multiplying by 15 gives ...

  x = 15/√3 . . . . . . matching choice D

__

There are other ways to get there. One of them is ...

  x = 15·tan(30°) = 15/√3
