A private school $860,000 in one year to pay all of its teachers and administrators. the school has a total of twenty-four teach

ehidna [41]

Hi there!

Let t be the number of teachers
Let a be the number of administrators

t+a=24
35,000t+40,000a=860,000
a=24-t
35,000t+40,000(24-t)=860,000
35,000t+960,000-40,000t=860,000
35,000t-40,000t=860,000-960,000
-5,000t=-100,000
t=-100,000/-5,000
t=20
a=24-t
a=24-20
a=4

Therefore there are 4 administrators and 20 teachers.

Hope this helps!

2) 23 and 24 are complementary angles. If m 23 = (x + 24)º and m 24 = (x )º, then

adoni [48]

Answer:

m<23 = 57° & m<24= 33°

Step-by-step explanation:

You have to create an equation that equals 90°.

(x+24)+x=90

2x+24=90

2x=66

x=33

m<23 = 33+24= 57° so m<23= 57°

m<24= 33°

Donte simplified the expression below. 4 (1 3 i) minus (8 minus 5 i). 4 3 i minus 8 5 i. negative 4 8 i. what mistake did donte

SCORPION-xisa [38]

Donte did a mistake that 'he did not apply the distributive property correctly for 4(1 3i)' option (A) is correct.

<h3>What is a complex number?</h3>

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have an expression:

= 4(1 + 3i) – (8 – 5i)

= 4 + 12i - 8 + 5i

He did not distribute the subtraction sign correctly for 8 – 5i.

= -4 + 17i

Thus, Donte did a mistake in that 'he did not apply the distributive property correctly for 4(1 3i)' option (A) is correct.

Given:

anygoal [31]

First off, remember PEMDAS. Then replace the variables with the values.
3(2x3)^2
First distribute the exponent to the value on the inside.
3(4x9)

Then multiply the 4 and 9.
3(36)

After that just distribute the 3.
3x36 = 108.

‼️‼️help please ASAP

Zanzabum

By the Triangle Angle-Sum Theorem, all the angles in a triangle have to add up to equal 180. Therefore, 180-35-88=57, second choice down.
