Answer:

The inequality is $8x+17\geq 137$

Step-by-step explanation:

Given : The isosceles triangle with base and side 4x+3, 2x+7.

And the perimeter is at least 137ft.

To write : An inequality for x

Solution : Let the base $b=4x+3$ and sides $s=2x+7$

The perimeter of Isosceles triangle is $P=2s+b$

where s=side and b=base

Now, we have given that perimeter is at least 137 ft.

Therefore, the inequality form is

$2(2x+7)+(4x+3)\geq 137$

$4x+14+4x+3\geq 137$

$8x+17\geq 137$

You have a 32-foot fence around a square garden. There are 4 equal sections. You paint 13 of one section of the fence.

Question:

You have a 32-foot fence around a square garden. There are 4 equal sections. You paint 1/3 of one section of the fence. What fraction of the fence did you paint?

Answer:

The fraction of the fence painted is $\frac{1}{12}$

Solution:

Given that:

You have a 32-foot fence around a square garden. There are 4 equal sections

Find the length of each section:

4 sections = 32 foot

$\text{ 1 section } = 32 \div 4 = 8 foot$

Find the length that is painted:

$\text{ Fence painted }= \frac{1}{3} \text{ of one section }\\\\\text{ Fence painted }= \frac{1}{3} \times 8 = \frac{8}{3} \text{ foot }$

Therefore $\frac{8}{3}$ foot of fence is painted

Find the fraction that that is painted:

Total length of fence = 32

$\text{ Fraction of the fence painted } = \frac{8}{3} \div 32 = \frac{8}{3} \times \frac{1}{32}\\\\\text{ Fraction of the fence painted } = \frac{1}{12}$

Therefore $\frac{1}{12}$ fraction of the fence is painted

If you answer a question put the number of the question in your answer. Thanks

Answer:

You'll find the answer below each.

Step-by-step explanation:

1-4 you can use this formula: $V=l*h*w$

$V=l*w*h\\V=(6ft)(4ft)(1ft)\\V=24ft^3$

$V=l*h*w\\V=(2yd)(\frac{1}{2}yd )(2yd)\\V=2yd^3$

$V=l*h*w\\V=(12\frac{1}{2}mm)(3mm)(4mm)\\V=150mm^3$

$V=l*h*w\\V=(2cm)(8.5cm)(2cm)\\V=34cm^3$

5-7 you need these 2 formulas: $A=\frac{bh}{2}$ and $V=Bh$ or you can use one formula which is: $V=\frac{bh}{2}*h$

Let me explain. The first formula is for finding the area of the base of the triangle and the second formula is for finding the volume of the prism using the area previously mentioned. The first h is with respect to the triangle and the second h is with respect to the prism.

$V=\frac{bh}{2}*h\\V=\frac{(8in)(6in)}{2}* 18in\\V=\frac{48in^2}{2}*18in\\ V=48in^2*9in\\V=432in^3$
