4) Here both smaller and larger triangle is "isosceles" in nature.
So, sum would be 180 with two equal sides.
66 + BDE + BED = 180
2 BDE = 180 - 66
BDE = 114 / 2
BDE = 57

<span>In short, Every four angles would be equal to 57

</span>5) A) 7
It is because it must be smaller than the longest side which is equal to 8

6) D) Yes, Because ∠C is congruent to ∠BED

Hope this helps!

Four more than thrice a number is greater than forty

Svetlanka [38]

Answer:

The unknown number is greater than equal to 12

Step-by-step explanation:

If we need to solve the equation will be

let the number be x

4+3x $\geq$ 40

3x $\geq$ 40-4

3x $\geq$ 36

x $\geq$ 36/3

x $\geq$ 12

This means x is greater or equal to 12

I NEED to know the answer and steps to figure out, Mark wants to paint a mural. He has 1 1/3 gallons of yellow paint, 1 1/4 gall

emmasim [6.3K]

Well, Mark has

1 1/3 of yellow paint

1 1/4 of green paint and

7/8 of blue paint

now, bear in mind, the yellow is a bucket and 1/3 more, the green one is one bucket and 1/4 more and the blue is 7/8 which is almost 8/8, so is almost a bucketfull.

Then he's going to use 3/4 of each, so, we'd have to subtract 3/4 from each, and there'll be some left still in the paint bucket.

How many will he have left altogether? well, we simply add the leftovers.

$\bf 1\frac{1}{3}\implies \cfrac{1\cdot 3+1}{3}\implies \cfrac{4}{3}
\\\\\\
\cfrac{4}{3}-\stackrel{\downarrow }{\cfrac{3}{4}}\implies \cfrac{16-9}{12}\implies \boxed{\cfrac{7}{12}}\\\\
-------------------------------\\\\
1\frac{1}{4}\implies \cfrac{1\cdot 4+1}{4}\implies \cfrac{5}{4}
\\\\\\
\cfrac{5}{4}-\stackrel{\downarrow }{\cfrac{3}{4}}\implies \cfrac{5-3}{4}\implies \cfrac{2}{4}\implies \boxed{\cfrac{1}{2}}\\\\
-------------------------------\\\\$

$\bf \cfrac{7}{8}-\stackrel{\downarrow }{\cfrac{3}{4}}\implies \cfrac{7-6
}{8}\implies \boxed{\cfrac{1}{8}}\\\\
-------------------------------\\\\
\textit{so the leftovers are }\cfrac{7}{12}+\cfrac{1}{2}+\cfrac{1}{8}\implies \cfrac{14+12+3}{24}\implies \cfrac{29}{24}\implies 1\frac{5}{24}$

These questions are in Spanish, someone who knows Spanish, the topic is mathematics, please.

The interest that Marcos will get is 50000.

<h3>How to calculate the interest?</h3>

The following can be deduced from the information given:

Principal = 50000

Interest rate = 12.5%

Time = 8 years

The simple interest will be:

= (PRT/100)

= (50000 × 12.5 × 8)/100

= 50000

The amount that will be obtained after 8 years will be:

= Principal + Interest

= 50000 + 50000

= 10000
