Answer:

Step-by-step explanation:

okay if the fact you're asking this means you don't understand the question not the math.

The question is saying the some number has a value that if 7 is subtracted from, will equal 15. So basically, x-7=15. x=15+7. x=22

spayn [35]

Answer:

option-C

option-D

Step-by-step explanation:

we are given

He estimates that he can afford monthly payments of $265 for 10 years in order to support his loan

so, firstly we will find total amount

$A=265\times 12\times 10$

$A=31800$

now, we can verify each options

option-A:

r=6.6% =0.066

Amount is same

$A=31800$

now, we can use APR formula

$A=P(1+\frac{r}{n})^{nt}$

It is compounded monthly

so, n=12

we can plug it and then we can solve for P

$31800=P(1+\frac{0.066}{12})^{12\times 10}$

$P=16465.6215$

we can see that it is less than 24418.05

So, this is FALSE

option-B:

r=6.2% =0.062

Amount is same

$A=31800$

now, we can use APR formula

$A=P(1+\frac{r}{n})^{nt}$

It is compounded monthly

so, n=12

we can plug it and then we can solve for P

$31800=P(1+\frac{0.062}{12})^{12\times 10}$

$P=17133.96$

we can see that it is less than 24418.05

So, this is FALSE

option-C:

r=5.2% =0.052

Amount is same

$A=31800$

now, we can use APR formula

$A=P(1+\frac{r}{n})^{nt}$

It is compounded monthly

so, n=12

we can plug it and then we can solve for P

$31800=P(1+\frac{0.052}{12})^{12\times 10}$

$P=18927.00451$

we can see that it is less than 24418.05

So, this is TRUE

option-D:

r=5.8% =0.058

Amount is same

$A=31800$

now, we can use APR formula

$A=P(1+\frac{r}{n})^{nt}$

It is compounded monthly

so, n=12

we can plug it and then we can solve for P

$31800=P(1+\frac{0.058}{12})^{12\times 10}$

$P=17829.66$

we can see that it is less than 24418.05

So, this is TRUE

Which rectangles have the same areas but greater perimeters than the one shown below? Choose all that apply.

Firlakuza [10]

The rectangles have the same areas but greater perimeters are 12 ft by 3 ft, 9 ft by 4 ft and 18 ft by 2 ft.

Area is the amount of space occupied by a two dimensional shape or object.

A rectangle is shown with a length and height of 6 ft. Hence:

Area = (6 * 6) = 36 ft²

Perimeter = 2(6 + 6) = 24 ft

For 12 ft by 3 ft:

Area = (12 * 3) = 36 ft²

Perimeter = 2(12 + 3) = 30 ft

For 9 ft by 4 ft:

Area = (9 * 4) = 36 ft²

Perimeter = 2(9 + 4) = 26 ft

For 8 ft by 3 ft:

Area = (8 * 3) = 24 ft²

Perimeter = 2(8 + 3) = 24 ft

For 7 ft by 4 ft:

Area = (7 * 4) = 28 ft²

Perimeter = 2(7 + 4) = 26 ft

For 18 ft by 2 ft:

Area = (18 * 2) = 36 ft²

Perimeter = 2(18 + 2) = 40 ft

The rectangles have the same areas but greater perimeters are 12 ft by 3 ft, 9 ft by 4 ft and 18 ft by 2 ft.

8. In AABC, mC = 90° and sin A =

svet-max [94.6K]

Answer:

Step-by-step explanation:

The degrees of a triangle add up to 180.

Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.

Angle A is equal to sinA=1/2.

sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.

90-30=60.

That leaves you with 60 degrees for angle B.
