Answer:

Answer for this question would be: A, 3.67

Answer:

A. 3.67

Step-by-step explanation:

1. Add the two vectors (2.5,1.8)+(-6,-.7)=(-3.5,1.1)

2. Find the magnitude using square root of a^2+b^2

sqrt(-3.5)^2+(1.1^2)=sqrt(12.25+1.21)=sqrt(13)=3.67

Answer:

x = 77.5

Step-by-step explanation:

Assuming that you meant:

0.4x+18 = -13

Subtract 18 on both sides:

0.4x = -31

Multiple by 5/2 on both sides

x = 77.5

Answer:

SA= 902.88 yd²

V = 1386.24 yd³

Step-by-step explanation:

Surface area

Since the bases are right triangles, you need to find the base of the triangle. Use Pythagorean theorem as you are given the hypotenuse and one leg.

19² = 15.2² + b²

361 = 231.04 + b²

Subtract 231.04 from both sides

b² = 129.96

Root that

b = 11.4

Now that you have the base, find the areas of the triangles and rectangles.

Triangles - (15.2*11.4)1/2 (2)

15.2*11.4 = 173.28

Rectangles - (15.2)(16) = 243.2

(16)(11.4) = 182.4

(16)(19) = 304

Add them all together and the SA equals 902.88 yd²

Volume

V = Bh

V = 1/2(15.2)(11.4)(16)

V = 1/2 (2772.48)

V = 1386.24 yd³

Out of 20 there are 5 cards which have flowers on them.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have total 20 thank-you cards.

Now, we choose four cards.

Out of 4 cards 2 with thank you then one with flowers that says thank you than on with a dragon fly

So, We choose pair of 4 cards 5 times.

Then, we get total cards with flower

= 1 x 5

The expanded form of 0.985 is  0.9 + 0.08 + 0.005.

Decimals are numbers that have two components, a whole number component and a fractional component, which are separated by a decimal point.

Example: 1.2 is the decimal number, where 1 is the whole part and 0.2 is the fractional part.

Given:

The decimal number 0.985.

To find the expanded form of 0.985:

First, convert the number to fractional form.

0.985 = 985/1000

          = 900/1000 + 80/1000 + 5/1000

          = 0.9 + 0.08 + 0.005

0.985 = 0.9 + 0.08 + 0.005

Therefore, 0.9 + 0.08 + 0.005 is the expanded form of 0.985.

Answer:

200°

Step-by-step explanation:

The angle subtended at the centre is equal to the measure of the intercepted arc, thus

arc MQ = 85° + 75° = 160°

The measure of the circle is 360°, thus

arc QRM = 360° - 160° = 200°

Answer:

[tex]\$180.55[/tex]

Step-by-step explanation:

step 1

Simple interest

we know that

The simple interest formula is equal to

[tex]A=P(1+rt)[/tex]

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=10\ years\\ P=\$2,250\\r=4\%=4/100=0.04[/tex]

substitute in the formula above

[tex]A=2,250(1+0.04*10)[/tex]

[tex]A=2,250(1.4)[/tex]

[tex]A=\$3,150[/tex]

step 2

Interest compounded annually

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=10\ years\\ P=\$2,250\\r=4\%=4/100=0.04\\n=1[/tex]

substitute in the formula above

[tex]A=2,250(1+\frac{0.04}{1})^{1*10}[/tex]  

[tex]A=2,250(1.04)^{10}[/tex]  

[tex]A=\$3,330.55[/tex]

Find the differences between the two final amounts

Answer:

$48

Step-by-step explanation:

To start off, we know that Avery put 20% of the $80 in her bank account. We can figure out how much 20% of 80 is by multiplying 80 by 20% and then subtracting that number from 80. Remember to switch 20% to its decimal form (20% -> .2).

Step 1) 80 x .2 = 16

Step 2) 80 - 16 = 64

Next, we have to figure out how much 1/4 of the remaining $64 would be. We just simply divide 64 by 4 to figure out how much Avery spent.

Step 3) 64 / 4 = 16

Lastly, since we know Avery spent 16 dollars, we can subtract the 16 from 64 to get our final answer.

Step 4) 64 - 16 = 48

Avery kept $44 of the $80 as cash after putting 20% into a bank account and spending 1/4 of it.

Avery received $80 in cash for mowing lawns. Let's calculate how much she kept after her transactions. First, she put 20% of the $80 into her bank account. Calculating 20% of $80 involves multiplying $80 by 0.20, resulting in $16. Next, Avery spent 1/4 of the $80, which equals $20, as $80 divided by 4 gives $20. To find the amount Avery kept as cash, we subtract the amounts she put in her bank and spent from the original $80.

$80 - $16 - $20 = $44

Therefore, Avery kept $44 of the $80 as cash.

3 up and 5 over from point to point

Answer:

3/5

Rise=3

Run=5

Step-by-step explanation:

For this question it makes it easy because they have provided you with Lines labeled Rise and Run. All you need to do now is Count the rise and run.

For Rise over run if you go up as a rise it's a positive number...But if you go down its a Negative number same with Run.... If it runs to the right its positive and if it runs to the left its negative.

For Rise it goes up...1,2,3 Spaces so Rise is 3

For run it moves to the Right 1,2,3,4,5 spaces so Run is 5

3/5 cant be reduce so it stays as a fraction.

Answer:

Step-by-step explanation:

let the width=x

length=4x

P=2(l+w)=2(4x+x)=10x

10x=40

x=40/10=4

width=4 in

length=4×4=16 in

area=16×4=64 square inches.

The required area of the given rectangle is given as 64 inch².

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

Here,
As mentioned in the question,
The length of a rectangle is four times the width.
l = 4w

Now,
The perimeter of the rectangle is 40 inches.
2 [l + w] = 40
2 [4w + w] = 40
5w = 20
w = 4 inches

Length,
l = 4(4) = 16 inches

Area of rectangle = l × w
                          = 16 × 4 = 64 inch²

Thus, the required area of the given rectangle is given as 64 inch².

Answer:

Slope is 5/7

Step-by-step explanation:

the slope of a line is given by;

m = (y-y1)/(x-x2)

Where;

y represents the coordinate of point 1 on the Y-axis

x represents the coordinate of point 1 on the X-axis

y1 represents the coordinate of point 2 on the Y-axis

x1 represents the coordinate of point 2 on the X-axis

Points on a line are written as the ordered pair (x, y)

We are given point 1 (2, -2) and it corresponds to (x, y)

Point 2 (9, 3) and it corresponds to (x1, y1)

Therefore the slope,

m = (-2-3)/(2-9)

m = -5/-7

m = 5/7

Therefore, the slope of the line through (2,−2) and (9, 3) is 5/7
