Find The Area Of The Isosceles Triangle.13 Cm Is The Side Length 10 Cm Is The Base Length What Is The

Answers

Answer 1

Answer:

The hight length : h

The base length : a

Apply the Pythagorean theorem in the right triangle :

h² = 13² - (10/2) = 144

h  = √144 = 12 cm

S = (a x h)/ 2 = ( 10 x 12 )/2 = 60 cm²

What is the y intercept of the line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3)

Answers

So the y intercept is at +5 so you’d draw a line going through (-3, -3) and make it cross the y-intercept which is at (0, 5) and you should be good

The line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.

What is the equation of a line?

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

The given equation of a line is y=-3/4x+5 and the coordinate point is (-3, -3)

Here, slope of a line is -3/4.

The slope of a line perpendicular to given line is m1=-1/m2

Now, the slope of a line is -4/3

Substitute m= -4/3 and (x, y) =(-3, -3) in y=mx+c, we get

-3=-4/3 (-3)+c

c=-7

Substitute m= -4/3 and c=-7 in y=mx+c, we get

y=-4/3x-7

Therefore, the line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.

Can someone explain the process of getting to Angle A? I know the answer is 44.1 but I need to show my work so can someone show me the process of getting the answer and please explain! Thank you!!

Answers

Answer:

Step-by-step explanation:

First you have to calculate CB in order to use sin law to calculate ∠A

CB=[tex]\sqrt{18.4^{2} -13.2^{2} }[/tex]

CB=12.8(correct to nearest tenth)

After that, use sin law to calculate ∠A,

[tex]\frac{18.4}{sin90} =\frac{12.8}{sinA}[/tex]       or    [tex]\frac{sin90}{18.4} =\frac{sinA}{12.8}[/tex]

sinA=0.695...

A=44.079...

  =44.1(corrext to the nearest tenth)

Savannah is making a quilt with squares that have side lengths of 15/16 foot each. Are the side lengths of the squares closer to 1/2 foot or 1 foot long? ​

Answers

Answer:

1 foot long

Step-by-step explanation:

If this fraction is closer to one it will be close to 16/16. And since 8 is half of 16, any fraction that is around 8/16 is closer to 1/2. 15 is closer 16 so this fraction is closer to one.

The side lengths of the squares is closer to 1 foot when rounded to the nearest foot length

What is rounding up numbers?

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Non-zero digits are always significant

Zeros between non-zero digits are always significant

Leading zeros are never significant

Trailing zeros are only significant if the number contains a decimal point

Given data ,

Let the side lengths of the squares after rounding be represented as A

Now , the value of A is

The side lengths of the quilt with square shape be = 15/16 foot

Now , on rounding the value 15/16 , we get

A = 0.9375 feet

And , the value of A is much closer to 1 foot

Therefore , the value of A is 1 foot

Hence , the side lengths of the squares after rounding is 1 foot

If QRS = MNP, QR = 11, QS = 15, MP = 2x + 1, S = 84, R = 32, and M = (17y - 4),

find the values of x and y.

pls answer quick

Answers

Answer:

x = 7 and y = 4

Step-by-step explanation:

If QRS = MNP, then QR = MN, RS = NP and QS = MP

Given

QR = 11

QS = 15

MP = 2x + 1

Recall that QS = MP

15 = 2x+1

2x = 15-1

2x = 14

x = 14/2

x = 7

Similarly

<Q = <M

<Q + <R + <S = 180

<Q + 32 + 84 = 180

<Q + 116 = 180

<Q = 180 - 116

<Q = 64 degrees

Since <M = 17y - 4

64 = 17y - 4

17y = 64+4

17y = 68

y = 68/17

y = 4

Hence x = 7 and y = 4

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Jack is 1.78 m tall and Amy is 5 cm taller than Jack.

Therefore, The sum of the height of Jack and 5 cm more is the height of

Amy.

Therefore,

178 cm + 5 cm = 183 cm is the height of Amy. (1m = 100 cm)

So, 183 cm is equal to 1,83 meters.
