Answer:

Step-by-step explanation:

area=(16+10)/2 ×4+10×6

=13×4+60

=52+60

=112 in²

area=10×10+1/2×4×6

=100+12

=112 in²

Answer:

A = 112 in²

Step-by-step explanation:

First, find the area of the square, which is 10 in. by 10 in.

10 × 10 = 100 in²

Next, find the area of the triangle using the formula: 1/2(base × height)

The base is 10 in. - 6 in. = 4 in.

The height is 16 in. - 10 in. = 6 in.

A = (1/2)(4 × 6) = (1/2)(24) = 12 in²

Add the two areas.

100 in² + 12 in² = 112 in²

Need help!! please/Thank you

NARA [144]

Answer:

$50~in$

Step-by-step explanation:

$perimter=AB+AM+BM$

$AM=2EM=2(9in)=18in$

$BM=25E=2(7in)=14in$

∠m= $180-$ (∠A+∠B)= 180-(70+40)

∠m= 70⇒ AB= AM⇒AB=18

$perimeter=18+14+18=$

$50~in$

hope it helps...

The slope of a line that is perpendicular to a line whose slope is 3/8 is

Molodets [167]

Answer:

-8/3

Step-by-step explanation:

We know that lines that are perpendicular have slopes that multiply to -1

m1 * m2 = -1

We know one slope is 3/8 and are looking for the perpendicular slope m2

3/8 * m2 = -1

Multiply each side by 8/3 to find m2

3/8*8/3 *m2 = -1*8/3

m2 = -8/3

If 3a-2b= 8 and a+3b=7 what is the value of 4a+b?

Fittoniya [83]

Step 1: Find the value of one variable in terms of the other.

$a+3b=7\\a=7-3b$

Step 2: Substitute the value you just found for this variable in the other equation.

$3a-2b=8\\3(7-3b)-2b=8\\21-9b-2b=8\\21-11b=8\\21=8+11b\\13=11b\\\frac{13}{11}=b\\ b=1\frac{2}{11}$

Step 3: Use your new value for the second variable to find the first.

$a+3b=7\\a+3(1\frac{2}{11})=7\\a+3\frac{6}{11}=7\\\\a=3\frac{5}{11}$

Now that we know the values for a and b we can find the value of 4a+b.

$4a+b\\4(3\frac{5}{11})+1\frac{2}{11}\\12+\frac{20}{11}+1\frac{2}{11}\\\\12+1\frac{9}{11}+1\frac{2}{11}\\\\\boxed{15}$

Please help me.........

marishachu [46]

Answer:

126 square feet

Step-by-step explanation:

The formula for the area of a triangle is ...

A = (1/2)bh . . . . . where b is the base length and h is the height

Here, you have a triangular face that has a base of 6 ft and a height of 14 ft. Its area is ...

A = (1/2)(6 ft)(14 ft) = 42 ft^2

The lateral area of the pyramid consists of 3 such triangles, so the lateral area is ...

LA = 3·(42 ft^2) = 126 ft^2
